To ensure comfort and safety indoor with a furnace structure, it is necessary to competently make the passage of the chimney through the overlap. Contra fire safety Provided simple rules Pipe settings. All work can be performed with your own hands.

To withdraw the chimney through the ceiling, it is necessary to build a node that provides the required distance from the ceiling materials to the pipe. These rules are governed by a special document in which certain recommendations are indicated:

• The distance from the surface of a concrete or brick chimney to the crates or rafters should be at least 13 centimeters.
• If the chimney is ceramic and without isolation, then the distance should be as minimum 25 cm. And if there is a heat insulating layer - 13 cm.

During the installation of the beam, these rules must be taken into account. Their step should be about 60 cm. These recommendations are applicable to pipes with insulation layer.

The outlet should have a diameter 11.5-12 cm. If a sandwich with a thermal insulation layer is performed through the ceiling, the nozzle must have a diameter of about 32 cm. On each side must be observed the distance is not less than 13 cm. To calculate the distance between the installed beams, you need 13 x 2 + 32As a result, it turns out 58 cm., What corresponds to the recommended 60 cm.

You can also calculate the distance of the pipe without isolation. If the nozzle with the inner diameter in 11.5 cm.The distance to the ceiling material should be at least 25 cm. In this case, there should be a distance between the beams 25 x 2 + 11.5What is equal to 61.5 cm. Such a step is recommended for the construction of the ceiling.

• If the partition is protected from possible ignition, then chimney thickness 12 cm. The distance should be about 26 cm. If the nozzle has a thickness of 5 cm. The distance is 38 cm.
• If the partition is not protected from fire, then in the first case the distance can reach 32 cm., And in the case of the second option - up to 50 cm.

The document also states that it is necessary to adhere to a certain distance from the walls. Often the chimney pipe is installed near the wall of the wall, which over time can lead to a fire, as the temperature inside the chimney may be 500 degrees. Therefore, it is necessary to put the heat insulating layer on the surface of the wall, after which it is coated metallic sheet.

Types of nodes

The flue of the chimney through the wooden overlap must be protected from high temperature and secure the nozzle in a special position. For this, the cutting is intended, the second name is "a passage node".

It is recommended to use the device industrial production. It is a special metal box, it is attached to it on one side. galvanized plate. In the middle there is a hole to insert a sandwich. On the part of the room, a special plate is installed, which closes the hole in the ceiling and acts as decorative element. The plate is also a support for the heat-insulating layer, which is placed in the gap between the beam and the surface of the pipe.

Many experts argue that the cutting from a stainless steel is the best option, since the galvanized leaf under the action of high temperatures highlights harmful substances. Therefore, it is recommended to use a stainless steel in a residential room or bath.

The ceiling node is simple enough. If at the construction stage, it was not possible to remove the stove, then between the beams it is necessary to make a hole of a certain size so that you can spend the chimney. Then secure the heat insulator. To do this, you can use Ministerith, stone cotton or asbestos. Specialists are also recommended to fix metal stripes.

A special device should be put on a pipe in a straight area that passes through the overlap. Then you need to raise it on the required level and fix the heat insulating layer at the edges. After that, the node is attached using self-tapping screws.

Products can have a different configuration. In some cases, a metal cylinder may be needed, which is installed around the hole, and plate edges A little advocate for him. It should be noted that when installing such a device, the hole must also have square shape. With the help of the plate, the hole is closed. Also, the ceiling materials from high temperature should also be protected using the heat insulator.

The node can be without a cylinder, but it is installed around the perimeter special boards from minit or metal. The edges of the device must be closed the heat insulating layer. It is recommended to use minyrites, as it acts as a heat insulator.

Pass over overlapping

When the chimney is derived through the ceiling, some nuances must be taken into account:

• Metal pipe without heat insulator should leave the furnace. Its length should be more than one meter, because at the output too big temperature. Above you can use a sandwich.
• In places of pass through the ceiling, the pipe must have a protected shell. To do this, you can use the industrial sandwich or with your own hands to warm the walls.
• The joints are permissible only before the passage or after it. Therefore, you need to control all connections.
• The horizontal portion may have a maximum meter length.
• All chimney can have a maximum of three knees.
• It is prohibited to use a rigid fastening, since under the action of high temperature the dimensions of the chimney change.

Selection of heat insulator

When the device on the ceiling is fixed, you need to rise to the next floor or attic to fill the distance between beams and chimneys.

If the temperature does not exceed the pipe 600 degreesYou can use basalt cotton as an insulator. However, some experts do not recommend using this option. They explain this by the fact that during the manufacturer the resins are used as a binder, and they allocate harmful formaldehyde Under the action of high temperatures. In addition, the chimney is formed condensate, when wetting, watts deteriorates heat-shielding characteristics. Therefore, this option is not the best.

Fill the gap can be small clay. This light and natural material, which in the case of wetting quickly restores its characteristics.

Until recently, most often used sand. But in this case, there is one substantial minus: over time, the material wakes up through small slots, so the stove must be constantly cleaning and replenished again.

You can use clay. To do this, it must be diluted so that it acquires a pasty consistency.

Some specialists do not recommend to warm the knot at all and leave it blank. This avoids the flue of the chimney and its overheating. But this option is not the best, since wood over time is overcameand there is a risk of fire.

How to independently equip the passage of pipes through the roof in a private house or bath

In the process of building any home, it is necessary to take a moment when it is necessary to derive stove or ventilation pipes through the roof, without it. Some owners do not give much This process, however, errors made during the arrangement of the docking unit can lead to serious negative consequences. In this material I will tell you how to remove the pipes through the attic overlap and different types of roofs.

What can cause low-quality installation

In most cases, cooking and ventilation specialists are engaged exclusively by mounting their sector. Pipes of pipes through the wall, inter-storey overlap and roofing them do not concern. Hiring a professional people do not want and take out about the work themselves. As a result, after a short period of time, a whole memory of the problems can "fab up".

When you hire a specialist, it is better to immediately approve the moment of arrangement of transitions through structures.
It is sometimes easier to pay a little more experienced person than later to break her head over how it is all right and beautiful to make it yourself.

• Materials from which chimneys are made are rather strainable, they can easily withstand the temperature differences, but for constant contact with moisture, these materials are often not designed. For example, or an asbetic tube, having liketing moisture, starts simply to paint and after a couple of seasons it will look like her mouse tree;
• Again due to high humidity, this sector from the inside will intensively overgrow the soottherefore, to clean the chimney will have much more often;
• But this is not the worst. In most cases, the roof is now insulating basalt or glass. It is worth it to wet this insulation, firstly, it becomes useless, and secondly, it sits down and is no longer restored. It is pointless to dry cotton, it only needs to be changed;
• Do not forget that almost all roofs are made based on wooden carcass . Whatever you so impregnate wood, but if the designs are constantly in a wet environment, it is sooner or later, they will begin to rot. Water stone sharpens that already talk about the tree;

• There is another momentI will explain it for example. One of my familiar in the fall ended the construction of the house and since the weather has already started to deteriorate noticeably, the passage through the roof of the chimney, hoping, in the hope that it will fix everything in the spring.

Imagine what was his surprise when there was a chimney passage through the ceiling of which was decorated in a pompous and very expensive baroque style, covered with red wet spots and began to fall off the stucco. And all this happened because the joke of the roof was not hermetic enough.

After the furnace was flooded, the snow around the pipe was stretched, the water flowed across the pipe and completely spoiled luxurious interiorwhose cost was ten times higher than the services of the most expensive roofer.

In which place is better to bring pipes

Of course, when the house was built for a long time and you, only repair the roof, can no longer change anything. But at the design stage you have the opportunity to choose optimal place To output pipes.

Any Michael will tell you that the passage knot is best to mount in the skate. But here is a stick about two ends. On the one hand, snow or rain will never leak under the pipe, plus the chimney located above the skate provides optimal traction. On the other hand, you will have to be pretty tinted with the arrangement of the rafter system, because the rupture of the horizontal skate beam is quite complex.

The minimum distance from the chimney to rafters or carrier beams According to SNIP 41-03-01-2003, 140 - 250 mm should be 140 - 250 mm.

• Usually it is recommended to slightly move the chimney into any of the sides relative to the skate. At the same time, if the pipe is at a distance of one and a half meters from the skate, it must rise above it at a height of 50 cm;
• If the distance from the skate to passion assembly hesitates in the area of \u200b\u200b1.5 - 3m, then in height, the pipe can be done in a skate;
• When the roof is a single-sided or distance from the ski beam to the passage node more than 3m, it is allowed to install the top point of the pipe along the line under the angle of 10º relative to the horizon of the skate. So that you were easier to figure out, the scheme is presented below.

The most undesirable place for the installation of chimney and ventilation pipes is the location of them in Undova. For those who do not know, enodova called internal cornerwhich is formed by connecting two roof slopes. It does not threaten the usual classic designs, this location can occur on multi-level roofs with a complex configuration.

If you faced the case when your passage of chimney pipes through the roof is in "Undova", it is better to try to make an excess knee and transfer the pipe half meter to the side.

For the so-called sandwich designs, of which most chimneys under boilers are being made and bath stoves, it will be easy. Otherwise, water will constantly attack your connecting knot from three sides and sooner or later there will be a flow.

Independent installation of passages through the roof or ceiling

If earlier the roofs for the most part were covered with slate, now it all more often huses metal tile and other modern roofing materials. Plus, in addition to passing through the roof, you need to take care of the transition through the ceiling overlap.

Elastic transitional block as the easiest way out

The good half of modern chimneys and almost all ventilation conclusions are now made round. This is just under such designs and elastic adapters are produced.

Such an adapter is a multi-stage funnel with a square or round base. The main material is used as a heat-resistant, elastic polymer.

Each step on the funnel corresponds to one of the head diameters of the chimney. In order for the pipe tightly entering you only need to trim the adapter with scissors for the level you need.

Hermetic fixation of the soft polymer base (flange) to the roof itself is carried out by metal studs and bolts. Such a flange can take any form, so it is easily enveloped by a complex roofing terrain.

The price of such goods is quite acceptable, plus the installation instruction, in my opinion, is more than simple. As I said, you first need to crop the cone to the desired diameter. After that, it is necessary to smear the heat-resistant sealant the place of the adapter dock with the pipe and the lower, the contact part of the flange. Next, you can only fasten the flange with metal studs through the dried in advance of the holes to the lower flange ring.

Insulated sandwich chimneys are distinguished by their mirror glitter. If you do not like the elastic polymer adapter, then for such cases there are metal adapters made from the same stainless steel. From the polymer counterpart, they differ in large dimensions of the apron, a given angle of inclination of the roof and a clearly defined diameter of the chimney.

Metal adapter.

From the previous version, the installation of such adapters from a stainless steel is distinguished by the fact that for the sealed adapter and the pipe, except the heat-resistant sealant, the metallic clamp is additionally used.

Arrangement of passage through metal tile

I want to immediately note that the passage of pipes through metal tile competently do, not having experience is pretty hard, so having studied the instructions and viewing themed photos And the video in this article, you should think well, whether you are capable of such a work feat.

The connecting assembly consists of an internal main and outdoor decorative apron. Inner apron Casting roofers are usually made from tin or thin aluminum sheet. We have already mentioned about the round pipes, so then we will talk about the sealing of the joint of the roof with square or rectangular brick trumpets.

The inner apron is installed directly to the crate before laying the metal tile. The design consists of 4 parts, by the number of pipe planes. Each of these parts should go under the metal tile layer at least 250 - 300 mm. It comes to 150 - 250 mm on the pipe, again from the metal tile layer.

Before installing the elements of the apron around the perimeter of the pipe at one level parallel to the roof of the grinder is cut out the depth of 10 - 15 mm. In it we will insert the top cut of the apron.

Before inserting elements of the apron in the stroke, it is cleaned, washed with water, dried and filled with heat-resistant sealant. Only sealant needs to be filled right before installing the protective elements.

On the plates themselves on the top slice bend under 90º side to the depth of the short. Personally, I did easier, I immediately inserted sheets in the stroke and tapping the hammer bending them down parallel to the pipe.

We finish the installation of apron with fastening it to the pipe with special heat-resistant dowels and the propagate junctions between all four elements. But this is not all, and the so-called tie will be started at the bottom of the roof under the apron and attached. This is a sheet of the same tin or aluminum, the width of which should exceed the size of the pipe at least half the meter on each side.

He must descend on the substrate to the edge of the roof. The tie is a kind of insurance, if somewhere decorative lining will begin to leak, the water on the tie will be drained under metal tile. Resulting in roofing pie will remain dry.

When the inner apron and tie are finally fixed on the pipe and the roof crate, you can start laying the metal tile. At the end, a decorative apron is mounted. Each of the manufacturers of metal tiles produces their challenges and makes them under the color of the roof.

Such aprons, as a rule, are corrugated aluminum or lead sheet, on back side which is applied self-adhesive coating. From above, such apron is equipped with a decorative plank, which is fixed on the pipe with self-proof. But before fixing, it is advisable to additionally wash the jack with heat resistant.

The top plank of the decorative apron is fastened slightly above the boundaries of the lower main apron, after it is fixed, the apron itself is carefully cutting rubber hammerSo that the corrugated sheet is well docked and glued to the complex surface of the metal tile.

The arrangement of transitions with soft modern roofing materials is approximately also, with the only difference that there often costs without a tie setting.

The main mistake of amateurs is that they are often neglected by mounting the main lower apron and tie, the decorative top apron holds, of course, well, but thin, soft aluminum corrugation barrier is not particularly reliable and it can hardly damage enough, for example, falling from the tree a branch .

How to protect the wooden foundation from a hot chimney

How do you remember, according to the standards of SNiP 41-03-01-2003, the minimum distance from the chimney to any wooden structures Starts from 140 mm. The most "advanced" relations are considered to be sandwich elements, but also there the insulation has a maximum thickness of only 100 mm.

We conclude, all chimneys when passing through structures wooden roof Or the wooden inter-storey overlap must be protected.

The passage of the pipe through the ceiling of the bath is the brightest illustration of this topic, since the baths in our Great Power are usually made from wood. It is still worth adding that the temperature in bathing furnaces is often higher than in ordinary.

It is believed that in order for dry wood to be charring, she needs only 200ºС. And when the temperature reaches 300ºС, the real danger of self-ignition appears.
If we consider that the birch firewood gives the temperature to 500 ° C, and when using good coal or coke, the temperature can rise above 700ºС, the scale of the danger becomes clear.

When arranging such transitions, you can go in two ways to buy a special transitional block or do everything with your own hands.

Now the industry produces a variety of ceiling passage nodes (PPU). In expensive designs of this plan there is a special enhanced box, which goes along with insulation, filler and other fittings. But how much I came across, our person does not want to pay money for such amenities and in this, I agree with him.

The fact is that the design itself is not particularly difficult and here, as it is often with us, it is cheaper to buy everything separately. At first I will tell you how the classical instruction looks like such an arrangement, and then I will tell you how I did the pipe transition through the ceiling of the bath with my own hands:

• Almost anyone construction market Now you can find special metal boxes with already ready-cut for a certain diameter of the chimney by hole;
• In the horizontal plate of such a box, which is at the same time part of the ceiling, the fastening holes under the tape are made around the perimeter. But immediately the design on the "naked" wooden ceiling It is impossible to mount. Its edges need to be pre-crushed not a combustible heat insulator. Most often for these purposes, an asbestos canvas is used;
• The dimensions of the vertical walls of the box are selected similarly to this calculation so that the asbestos can be used between them and the passing hole;

• From the inside, the vertical walls of the box should be laid with a foil base with a thickness of 30 - 50 mm, it costs it is of course more than the usual, but such is the instruction;
• Absolutely clearly without the slightest clearance, pick holes in the box under the chimney is almost unrealistic, at least a small gap, but still it will be. Here it is supposed to smear with heat-resistant sealant;
• Further, the space between the foil basalt car and the chimney is filled with clay or the same cotton, only soft and without coating. For non-residential attic overlap This is enough, but if the bath is an attic type, and on the second floor there is a living room, then the box should be covered with a stove from mineritis (heat-resistant and safer asbestos analogue) or the same stainless steel plate.

Now, as I promised, I will tell you about my own experience of arranging such a transition. The bath was done for a long time, and then these comfortable devices Simply was not. The design sandwich at that time was worth a fabulous money, therefore an overhexic cast iron tube was installed as a chimney.

The square opening in the wooden floors was cut out with the calculation so that in all directions between the chimney and the wood it was at least 250 mm. At the vertical walls of the niche, I immediately naked asbestos canvas.

A three-million meter sheet of stainless steel was late below. I wanted to last a ten-minute meter asbetic slab, but I was afraid that it would burst at the temperature, although the neighbor was kept and standing so far.

The pipe in the box I wrapped asbestos canvas and walked the clearance on top of it. And on top, all this farm fell asleep with an average diameter clay. On the second floor of the bath, I decided to make a rest room, but I didn't find the second of the same sheet of stainless steel at that time.

Then I mixed up a cement-limestrine based on clay sand and flooded with a thirty millionth-reinforced knitting scial. Only the screed was not close to cast iron trumpet, and through the laying of asbestos canvas, otherwise, at temperature fluctuations, it would be simply cracked.

Output

As you can see, you can make the passage through the roof of the chimney with your own hands. But still, if you decide to spend money on a high-quality coating of metal tile or other similar materials, I recommend first to carefully examine the available methods. If you have any questions, write them in the comment, I will try to answer.

How to remove the pipe in the bath through the ceiling? With this question, many owners of houses and baths equipped with furnaces are facing. When installing the chimney in the bath, an important point is the passage of pipe through the ceiling. If the structure is made of wood, then the correct chimney becomes the primary task to ensure fire safety. Only thorough compliance with all established norms guarantees a long and uninterrupted service of your property.

Before making a pipe in a bath through the ceiling, we recommend reading the following recommendations.

Safety regulations

By installing the chimney in the bath through the ceiling, it is necessary to be guided by the recommendations. Sanitary norms and Rules 41 - 01 - 2003. According to claim 6.6.22, it is necessary to ensure a distance of 130 mm in the case of a passage through the ceiling for the chimney of a brick pipe, providing wood protection. But considering that in most cases metal pipes apply in the baths, then you need to focus on the following norms:

• It is necessary to comply with the distance greater than 380 mm to easily flammable items protected by insulation;
• The minimum distance to easily flammable items without insulation should be more than 500 mm.

In this case, these distances need to be ensured to contact the pipeline with a tree.

Ideally, these distances would not close anything at all, but this option will contribute to the high heat loss, which is economically unprofitable. Therefore, the specified volume is closed by non-flammable materials.

The maximum length of the pipe passing through the ceiling in the bath should not be more than 1000 mm. The chimney can not gain a roof on the roof in a hard way, because when the temperature changes, the pipe can be somewhat vary in size, which can lead to the deformation of the overlap.

In the bath, pipes are often used, called Sandwich. They represent two pipes of different diameters, one of which is inside another. The space between them is filled with a layer of insulation. Not many know that the outer part of this design has almost the same temperature as interior chimney.

Need to know! The main purpose of such a device is to ensure normal thrust, and not at all the improvement of fire protection properties.

Often the hosts, in order to accelerate the battery, allow overheating oven. If the temperature of the outer part of the pipe exceeds the allowable values \u200b\u200bof 400 ºС, then it threatens the failure of the external part of the sandwich, which will lead to a threat of a fire. Therefore, in no case cannot be allowed to reduce the distance between the pipe and the surrounding objects.

The distance to combustible structures in the case of using pipes from brick or concrete should be at least 13 cm. For ceramic pipes that are not equipped with insulation, the corresponding distance will be greater than 25 cm, for pipes with insulation - 13 cm.

It is advisable to lay these parameters even at the design stage of the bath, since the step when installing the ceiling beams is usually not large. If it equals 60 cm, it will be possible to use only insulated pipes.

The diameter of the output part of the pipe often occurs 11.5 - 12 cm. If a 50 cm thick insulation is used in a sandwich, we obtain the outer portion diameter of 31.5 - 32 cm. We add a distance recommended for insulated constructions at 13 cm on each side, we get width 57, 5 cm. That is, such a design fits perfectly into the existing distance between the beams 60 cm.

Now let's see how much the distance between the beams should be when using a non-warmed chimney. If the inner diameter is 11.5 mm, then add to it necessary according to safety rules the distance from all sides of 25 cm, we get 61.5 cm. The resulting result does not fit into the existing distance between the beams. Moreover, the diameter of the pipe can be even more, and then the incompression of the size of the chimney and the beam step becomes even more noticeable.

Tip! In the instructions for furnaces, manufacturers usually indicate the distance, the minimum necessary for the passage of the chimney through the overlap of different materials. Building chimney, use these values.

Fireproof

So, what isolation material is better to use for heat shields, building the flow of chimney through the ceiling with their own hands?

• Mineral wool. Keeps its properties up to 300 º C. Higher temperature (up to 1000 ºС) is able to withstand the hard minevat PJ - 175. The disadvantage is the allocation of formaldehyde, which can harm health. It is also not sufficiently resistant to water;
• Ceramzit. Well tolerate wetting. The disadvantage is the need to facilitate additional containers for its placement;
• Basalt cardboard. Environmentally safe. 5 mm thick sheet can withstand temperatures up to 900 ºС;
• Asbestos. It copes perfectly with flame retardant, but it distinguishes harmful substances. Therefore, in the case of its use for the chimney, it is necessary to isolate the room from it using metal sheets;
• Minrit. It is able to withstand heating to 600 ºС, not destroying from water and being absolutely eco-friendly material.

Some experts still use sand or clay for thermal insulation, but this method is gradually moving into the past.

It is possible to reduce the likelihood of ignition using several other ways.

• Building on the chimney of a water shirt. This will require a remote tank. Will also be required cold water. But the resulting hot water will be able to be used in the shower or for heating. But the temperatures are significantly reduced above the water shirt, which will reduce the likelihood of pipe root;
• You can arrange a water tank over the stove, thereby protecting the chimney from excessive heating. But with this method, we will have to constantly ensure that water in the tank does not boil and pour cold water on time;
• Stop stones on the pipe. It will take a support for the redistribution of their mass.

Using all these methods, it is possible to achieve a decrease in temperature in the installed passage, which will significantly increase fire safety.

To increase fire safety in the bath, you can use materials such as glass jammed sheets and fire-resistant plasterboard sheets. They are used, covering them the overlaps and holes in them, through which the chimney passes. Only sheets of class premium, marked "NG" are suitable as flame retardants. If there is no such marking, it is impossible to use such products to protect against fire.

Construction of transition through overlapping

Consider how to make chimney in the bath through the ceiling. This can be done in two ways.

• Use finished cutting;
• Mount the passage knot with your own hands.

Application of finished cutting

In order to fully protect the elements of the roof from the effects of high temperatures arising from the passage of the combustion products, and at the same time fasten the pipe in the required position, the so-called ceiling cutting is used.

To build the passage of chimney through the overlap, it is necessary to purchase a passing ceiling knot for the chimney in the construction store. It is a box made of mineritis or metal connected to a stainless steel plate. In the center of the design there is a hole in which the sandwich is placed. Such a device performs, among other things, a decorative function. The plate attached to it closes the ceiling hole, giving it a more aesthetic look. In addition, the insulation is based on this plate, which is filled with a place between elements of overlapping and pipe.

They are two species:

With insulation, looking like two plates in combination with an insulated pipe;

Without insulation, which represents a box made of metal to be filling insulating materials Pred and a hole intended for installation of pipes.

Cutting are found different shapes. Sometimes they look like a metal cylinder, in which case the plate significantly exceeds it in size. If such a device is used, and the ceiling hole has square formAll the same, you must comply with all the listed parameters required to provide fire safety design. At the same time, it is necessary to strengthen the protection of wooden structures of the bath with metal strips.

Installation of a finished adapter

• Cut hole in the ceiling, taking into account dimensions cutting;
• If necessary, carry out insulation;
• Set the passage knot of the chimney into the overlap;
• Take the pipe to the ceiling, while its length should be 100-150 mm less than height;
• Attach the pipe area located on top of the roof;
• Conduct the sealing of all the joints that arose in the exercise of the flock tube through the wooden overlap.

Installing an adapter performed by hand

You can carry out a chimney through the ceiling in the bath and without factory nodes.

Consider how to make a ceiling-through a node with your own hands. This will require:

Material selected for thermal insulation of the passage of the pipe through the ceiling of the bath;

Metal plates.

The tube in the bath through the ceiling and the roof is set, following the recommendations described below.

• Cut in the overlap hole exceeding the size of the pipe by 13-18 mm;
• One edge of the pipe is displayed in the hole;
• From the inside of the room on the ceiling is superimposed;
• The heap of the flue of the chimney through the ceiling is carried out. Optimal is the manufacture of thermal insulation of the ceiling of the passage node from Minister.
• The space remaining between the ceiling and plate must also be filled with a layer of insulation.
• The plate is fastened with the help of screws.

Thinking on how to install a pipe in a bath through the ceiling, be sure to pay attention to such an important factor as the choice of a suitable place to pass overlap for the chimney.

It can be installed either directly at the skate, while ensuring good traction and the absence of precipitation; Either next to the skate.

Attention! Never install the chimney in the place where the roofs are connected.

The chimney set by their own hands will require a slightly longer than purchased in the store, but will help save money so necessary during construction.

By installing the cutting in the ceiling - the roofing overlap, the masters often face such complexity as the need to make chimney in the bath through the ceiling is strictly vertically, after placing it in the center of the passage. To do this, you can recommend using a plumb. It is raised upstairs and lowered into the center of the chimney. This point is celebrated on the ceiling and used as an appropriate mark before making the passage of pipes through the ceiling of the bath.

Rules for passing through the overlap

Before spending the chimney through the wooden overlap, you must read the rules for installing the ceiling passage node for the chimney with their own hands.

• On the outlet of the furnace, only a metal tube with thick walls without heat insulation is installed. This is due to the fact that in this place temperature reaches such values \u200b\u200bthat are not able to withstand mineral materials.
• The tube in the bath through the ceiling and the roof is carried out surrounded by the insulation material.

• In the places of the pipe in the bath through the ceiling, the presence of joints are allowed when crossing overlaps. They are possible either lower or above them;
• The horizontal portion should not exceed 1m;
• The maximum number of knees when the chimney is ave in the bath through the ceiling - three;
• The passage of the pipe through the ceiling in the bath is not allowed to fasten the hard way.

Isolation of jigs

Building a cutting pipe on the ceiling of the bath, use sealants that ensure the strength of the joints and withstand high temperatures.

The clamps used in the design must be made of the same material as the chimney itself.

Careful processing of the passage of the pipe through the roof is very important. Otherwise, the following consequences are possible:

The penetration of moisture inside the chimney can lead to gradual destruction of the structure, the consequence of the penetration of smoke between the roof and overlapping, and, consequently, will increase the risk of fire;

The liquid accumulating inside the chimney can lead to the formation of fungus and rust;

Violation of tightness can lead to an increase in heat loss;

Water entering the roof can lead to rotation of the rafter design.

For additional protection against water from entering, special "aprons" are used. They are different: made of metal and thanks to this harsh adjacent to the roof; embedded in advance in the sheet used to cover the roof; Flexible, made of plastic materials - rubber or silicone. The size of these aprons must be chosen, given the diameter of the chimney pipe.

Therefore, the sealing of all joints is final, but at the same time an extremely important point of the dedication of the chimney.

The chimney withdrawal: Requirements, how to make chimney in a bath and bring out a ceiling

Despite enough simple technology Bath construction, in the process of performing work, has to solve a number of sufficiently complex issues. One of them is the withdrawal of a chimney pipe through the ceiling outward. This operation needs to be given special attentionSince the safety and service life of the structure depends on the execution.

If you make miscalculations at this stage, it will be impossible to comply with the fire safety requirements. So it is better to do everything to the maximum than to subside. This is unlikely to have any doubts about someone. Therefore, each private developer rules must comply withconcerning the competent making of the flow of chimney through the ceiling in the bath.

About distances to combustible structures

For correct I. safe work Bath pipe must be output through a specially created alert node in the ceiling. Thanks to this device, a safe distance from the outer surface of the pipe to the ceiling overlap materials will be withstanding. it the requirement is enshrined by SNiP 2.04.05-91. In accordance with it, you need to do the following:

The distance between the combustible rafters and the crate and the outer surface of brick and concrete pipes should be at least 130 mm;

• Between the overlap and the surface of the ceramic pipe without isolation, a distance of at least 250 mm should be withstanding, and between the pipe with thermal insulation - 130 mm.

It is based on these meanings that it is necessary to install the blocking beams with their own hands. They should be installed at a distance of about 60 cm. But such a step can be withstanding only in the case of using pipes with insulation.

Attention should be done and cross section of the outlet furnacewhich is usually 115-120 mm. Sometimes there is a thermal insulating sandwich with a thickness of 100 mm using a passage. In this case, it is allowed to increase the cross section to 315-320 mm. On both parties should be a step of at least 130 mm. Taking into account the observance of the above-described requirement, we obtain the adjacent beams will be located apart from each other at a distance of 575 mm (130 mm * 2 + 315 mm). It just allows you to observe the recommended step 60 cm.

It is still necessary to determine the minimum pitch for the pipe without heat insulation. With the internal cross section of the chimney, 115 mm safe will be considered a distance in which the outer edge of the pipe is removed from combustible materials by 250 mm. Installation of beams must be made in increments of 516 mm (250 mm * 2 + 115 mm).

Although deviations are small, but still in the specified interval does not fit. The calculated scheme is designed for chimney Medium sizes. But in some baths, pipes are used and with a large cross section. Be that as it may, if you have not yet proceeded to the ceiling device, be sure to take into account the distance when placing the beams.

If you contact Appendix 16, then there you can find recommendations for the dispatch (distance from external surface Pipes to combustible materials):

For partitions equipped with a protective coating:

• For pipes with a thickness of 120 mm - 200-260 mm;
• for pipes with a thickness of 65 mm - 380 mm.

For partitions that do not have special protection:

• For pipes with a thickness of 120 mm - 260-320 mm;
• For pipes with a thickness of 65 mm - 320-500 mm.

All these distances clearly show what should be recommended indentation from the walls. They are given due to the fact that in many buildings the chimney pipe is satisfied with the immediate vicinity of the walls. At the same time, the wall material also needs to protect against fire. The reason for this is simple: flue gases emerging from the furnace may have a temperature of 500 ° C. In the absence of wooden walls Special protection after some time they are glowing, and later they can flash. Considering these risks, it is necessary to fasten the thermal insulating layer on the wall surface, and fill the sheet of polished stainless steel on top of it.

Types of passing units through the ceiling

During the outlet device for chimney pipe with your own hands materials "Pie" are exposed Cleansing, which also begin to experience the heat. They must be protected, and in addition to this, correctly fasten the pipe in the correct position. It is for this purpose that the ceiling cutting is used, which is also called a passage node.

The easiest way to solve the problem of the decomposition of chimney through the ceiling is to purchase a passing unit of industrial manufacture. It looks like a box made of metal or minorite, having a stainless or galvanized steel plate fixed on one side. In the center of this node there is a hole where the sandwich is inserted. Plate that will be attached from the side of the room will help close hole in the ceiling, speaking here in the role of a decorative element. It also performs the function of the support for the heat insulator, which is used to seal the space between the pipe and the beams of the overlap.

All experts agree on the choice suitable material For the manufacture of penetrations in the bath. It should be only a stainless steel. This is explained by the fact that the prevailing in paired temperature as a result of exposure cause material to highlight harmful substances. In case of use of stainless steel, such a hazard for health is excluded.

Make a passage knot with your own hands is quite simple. If the ceiling design is already present in the bath, but completed without taking into account the passage of the pipe, then in the site selected for the node put a square hole The cross section is 12 cm less than a decorative panel. On the beams and boards are laid by a layer of insulation. If possible, you can additionally secure the minitite, basalt or asbestos-cement cardboard bands. Also suitable and a string of isolation from stone wool. Sometimes it may be necessary to make a pickup of the insulation with metal strips.

As for the features of the installation in the bath tube on the furnace with their own hands, the device must be put on a straight plot that will be held on crossing overlap. From the artist is required only raise a node of passage on the height. Under the edges of the device that will be on the same level with the ceiling boards, you need to put the insulation band, and then the finish fastening is performed using self-tapping screws. Very often, factory passage knots are already perforated under the self-tapping screw, so they will not need to be prepared before installation.

Passing units for chimney in the bath can have a different shape. In some cases, a metal cylinder is embedded around the perimeter for chimney. In this case, the edges of the decorative plate will go beyond the cylinder for a sufficiently large distance. If you plan to use a passing unit of a similar shape, then the opening is still needed give a square shape. It is permissible here and the round form, but then you will have to withstand the distance between its edge and the pipe 130 mm in the presence of insulation on the pipe or 250 mm in its absence.

In the process of implementing this option, you should pay attention to the following: The plate area should be sufficient so that it can close the entire hole. When using a node of such a form, it is necessary to protect the tree not only insulation, but also with metal stripes.

Sometimes there can be used in the bath without a cylinder around the pipe, but at the same time they may be at the perimeter of outdoor sides. Most often they are made of metal, although products from Minister are found. When using a node with metal sides, it is necessary to climb the edges of the hole in the ceiling by insulation, for example, basalt cardboard. If the sides are made of Minister, then this operation does not have to do, since the material has good thermal insulating properties.

Rules of passage through the ceiling

Engage in preparation for the device hole for the output of the chimney in the bath, you it is necessary to comply with a number of rules:

In the place where the pipe comes out of the bath, it is allowed to install only the metal pipe of a sufficient wall thickness without insulation. It should have a height of at least 1 m. Due to the critical temperatures created at the output, even the stainless steel in combination with a mineral wool insulation will not be able to cope with such a thermal effect. On more high levels The design of the chimney is allowed to use sandwich pipes.

• To bring the chimney in the bath with their own hands through a hole in the ceiling, a pipe is used in a protective sheath. As the latter, a factory sandwich can act, but if desired, you can perform insulation thin Wall Pipe yourself.
• Special attention is paid to the crossing sections, where there should be no joints before either. When calculating the height of sections, proceed from you to have the possibility of visual control of the state of all connections.
• For the horizontal section, the length of the length should be no more than 1 m.
• The entire length of the chimney design in the bath is allowed to use no more than 3 knees.
• It is forbidden to make a rigid fastening of the pipe to the overlap. In the case of temperature drops, it will begin to deform, which will lead to its displacement.

What heat insulator use?

Having completed the installation of the passage node on the ceiling with their own hands, work continue in the attic or the second floor where it is necessary to close the space between outdoor wall Pipes and beams insulation.

Basalt Vata.

Basalt wool is suitable for the heat insulator. Before buying, be sure to make sure that it can withstand the temperature of more than 600 ° C.

There is an opinion that this is a non-optimal option for such work. This is explained by the following. This insulation is manufactured using a binder resin, which, exposed to high temperatures, begin to allocate formaldehyde. In addition, on the pipe sometimes begins to flow condensate. As a result of the interaction of mineral wool with moisture, the first deprived of its heat shielding properties. As moisture evaporates, the property is restored only partially. So consider the ideal option Basalt cotton can not.

In addition to the insulation in the passage space in the bath, it is necessary to put the grainsite of medium and small grain. It is known to builders as natural material, characterized by a sufficiently low weight. His main plus is that even after wetting he restores its properties. But after contact with moisture, its thermal conducting characteristics increase slightly, although they are already very low even in comparison with mineral wool.

At one time, instead of a ceramisite, sand was used as a sealer. In principle, he arranged to everyone with the exception of one point: due to fine-grained, he constantly wakes up through the gaps. As a result, the owner has to follow the amount of sand and, if necessary, replenish it. However, it is unlikely that anyone will be nice to collect sand from the stove.

Among the natural insulation, you can choose clay. Before use, it is mixed with water to a pasty state, and then the mixture close up the entire gap. Sometimes clamzit is used as a filler.

According to some owners, use the insulator of the passage node in the bath is not very correct. It is believed that nothing will happen if the space is not filled. This will help prevent overheating and burning This part of the design of the chimney, and thanks to the ventilation created in this place, the pipe section will be faster. Perhaps everything is so, however, it must be borne in mind that the hot tube radiates heat, which will begin to dry the nearby tree. And then the ignition can occur at a lower temperature of + 50 ° C.

Conclusion

The withdrawal of the chimney through the ceiling overlap with their own hands is the necessary operation in the construction of the bath. However, here you need to be very attentive due to a possible fire hazardous situation. In the process of operation of the furnace, a plot located near the ceiling overlap, will heat up to high temperatures And maybe at a certain point call fire, if you do not take measures to protect. To do this, step by step perform a special alteration called the passing unit. But it is necessary to withstand the recommended distances to accommodate this device relative to the overlap materials.

We carry out the right installation of the chimney in the bath: pass through the ceiling and roof

Today we will talk about a purely bath subject. By building the long-awaited steam room and buying a stove for her, many are asked as a question. How to install a pipe in a bath through the ceiling to do everything quickly and safely?

From practice I know what the illiterate installation of the chimney can lead to. Some migrant workers (I don't want to say anything bad about them, many work fine and responsibly performing the task) to speed up the work process violate elementary requirements. In this case, the fire is frequent phenomenon. I can remember two similar incidents in our small town. They occurred precisely because of poor thermal insulation between the pipe and the ceiling overlap.

Something neither started, let's go to the case. First of all, we will pay the attention of fire safety baths, as well as all the intricacies of this work ...

We carry out the chimney through the ceiling

The first thing to be done is to determine the exact location where the oven will be installed. Although, this issue must be solved at the stage of planning and designing all premises. What should take into account?

First, the chimney passing through the ceiling should not be near the beams and rafters. Otherwise, the question may arise: how to remove them (which is extremely problematic) or how to protect them from fire. In order not to warm your head on this, think over this nuance in advance.

Secondly, the furnace should be located in a convenient place for you. The correct location of the woodcutter, some kind of furnace accessories, open doors etc. Do not give you inconvenience. It should also be taken into account where the hot water tank will be located and whether it will be in general (you can have an electric or gas boiler).

Well, the place was determined, the furnace was installed. Now we prepare or buy the chimney itself and all the "Priesges" that will be required. Here I mean sandwich tubes and additional elements, in detail of which you can read in another article. Chimney for the bath of this type is the most practical and demanded today. This option will be considered further ...

In order to accurately place the ceiling overlap, take the usual plumb (I think it is not necessary to explain what it is) raise to the ceiling. At the same time, the cargo of the plumb must be in the middle of the chimney the furnace channel. We celebrate on the ceiling, the place that the "smart device" showed us. This is the center where the bath tube will be held.

Next, we take the ceiling by the passage box, which is included in the category "The necessary Prosges" and place the hole in its size in the ceiling. This hole can be made by 1-2 centimeters more. There is nothing terrible in it, since it will close everything constructive feature The box itself, and on the side of the attic, the remaining slots can be closed with the same stone cotton.

Next, cut the hole in the ceiling of the desired size. It all depends on what tool you have. The best option, of course - chainsaw. Quickly and efficiently. Just before check the absence of nails, screws and others metal objects In the cutting area of \u200b\u200ba wooden ceiling. Any insulation must also be absent, especially flax or jute. The work of the chain saw for these materials is unacceptable, you can spoil the tire (there is already a sad experience). Go ahead…

The main points of exit through the roof

Now the next stage: it is necessary to "sleep" the roof and roof. An employed, but necessary. Nope again from marking. If you compare with the ceiling, then there are already marked differently. The roof, as a rule, has a slope. And the more this angle of the slope, the greater the area of \u200b\u200bthe hole carved under the chimney.

With lateral vertical marking, everything is simple: retreat from the sandwich pipe 10-15 centimeters and cut down wooden doom. With horizontal top and especially lower markup more complicated. Here it is necessary to take into account the slope of the roof and be climbing with the bottom board of the root. Make sure that it is not too close to the chimney.

The roof itself will have to cut in the form of an oval. Again, the greater the angle of the roof, the more stretched the hole will turn out. To close the cutting hole from the street, use special rubber seals. In common, they are called "flash drives". They are called - roofing seals. Very comfortable and practical thing.

By the way, at the expense of "flash drives". Always buy it with the desired slope, under the corner of your roof. Often managers in retail chains offer a direct version of the sealer flash. In practice, it can be highly supplied only on a horizontal surface. Consider this moment.

Iron Pipe Chimney

Quite often, especially in rural areas, an iron chimney for a bath is used. That is, the usual iron pipe with a diameter of 100-110 mm is used. The option is not quite the best, but has the right to exist. Here it is already ceiling the passage node (PPU) is performed differently. The distance from the metal pipe to wooden structures should be 40-50 centimeters.

The chimney itself in the area of \u200b\u200bthe ceiling passage and in the attic is wedgered by leaf asbestos. It is pre-wetted by water so that it does not crack when the bends. From above, such an wrapped pipe can be cooled with wire. She will not allow asbestos to "slip" down.

From the side of the steam, the hole made is closed with a sheet of stainless steel or ordinary thin metal. But under this sheet it is also necessary to put asbestos or paronite. The goal is to reduce heat exchange between this metal and finishing finish, for example, clapboard. From above on a metal sheet, clamzit is falling asleep or the basalt insulation is stacked.

In order to close the roof, the flash seal for this pipe is no longer suitable. Rubber simply will not withstand high temperatures. They come as follows: The carved hole is closed with a metal sheet, and the gaps between the pipe close the rope asbestos, which is abundantly wetted in a thick cement solution (just wrapped around the pipe). As they say: cheap and angry.

• Before Use the ceiling through the passage box, even if you use a sandwich. It is filled with clay, foam glass or mineral wool. Do not fall asleep the ground-cutting space of the earth, the more sand. Sand has a property to heat hard and long keep warm.
• The most optimal height of the chimney is 4.5-5 meters. Try to stick to these parameters.
• The top edge of the pipe should rise above the skate at least 50 centimeters. But, and if the roof is flat, then the height should already be at least meter. With a high height of the chimney, special deficing is mounted.
• In the steam room, if the pipe passes near the wall or partition, then a protective screen is installed on the wall. It can be in the form of a stainless steel or basalt cardboard.
• When installing "flash drives", it is recommended to use a special thermo and weather-resistant sealant. He perfectly copes with the task assigned to him. By the way, during the assembly of the chimney sandwich, the same thermoegertic is often used, and sometimes crimping clamps.
• If combustible roofing material is used, then the presence of a sparker is required. It can be done independently, applying a spent air "KAMAZ" filter.
• Try to avoid the joints of the pipe sandwich in the ceiling pass. In this place the smoke channel must be solid.

How to install a pipe in a bath through the ceiling

We carry out the correct installation of the chimney in the bath. How to safely go through the ceiling and roof. Some people of the cooking.

How to spend the pipe in the bath through the ceiling and roof

The construction of the chimney channel to the furnace provides for the need to conduct it through the ceiling overlap and output to the roof. The pipe for the bath through the roof should be held in full compliance with the rules of fire safety. Otherwise, the possibility of the occurrence of fires is enhanced, which will cause harm to human health.

Roof chimney

Safety regulations

The passage of pipes through the ceiling of the bath is regulated by SNiP 41-01-2003. This document says that:

• the passage of the bath tube in the ceiling should be located at a minimum distance of 350 mm from easily flammable structures and 250 mm from difficultly flammable elements;
• ideal is considered to be not closed (air). However, such a design will lose a large number of heat;
• the specified distance is filled with non-flammable materials;
• the hole must be closed with metal sheets (more often used stainless steel, which does not spoil appearance premises);
• the pipe in the bath through the ceiling and the roof should not have junctions. This factor must be taken into account when constructing the chimney;
• the maximum length of the pipeline passing through the ceiling or roof should not exceed 1 m;
• chimney should not be attached to overlapping or roof hard.

Selection of thermal insulation material

The thermal insulator can be the following materials:

• basalt or mineral wool. The insulation is able to withstand heating to 600ºС. The main disadvantages are: allocating formaldehyde, since the material includes resins and instability of protective qualities during wetting, which is possible in the case of condensation;

• ceramzit. Material has excellent properties. When wetting, the ceramzite quickly restores its functions. However, to arrange the overlap will have to additionally put the containers in which the material will be located;

Ceramizite of the middle fraction

• minrit. The material consists of cement, cellulose and mineral fillers. Mineritis tiles can withstand temperatures up to 600ºС. When heated does not highlight harmful substancesand when water gets into water does not lose its properties;

• asbestos. Is a good insulating material, but with severe heating allocates substances harmful to humans;
• sand or clay. Materials were used as thermal insulators earlier before the appearance modern insulation. However, some experts prefer to use natural materials than artificial.

Isolation of joints of pipes

To make tightness joints apply:

• high-strength sealants capable of withstanding large drops temperatures;
• special clamps made from the same material as chimney.

Ceiling overlap

How to remove a pipe from the bath through the ceiling? You can:

• purchase ready-made cuts;
• make the transition yourself.

Ceiling crossing with finished cutting

The finished shelf knot is designed to facilitate the work on the arrangement of the ceiling transition. You can purchase this element of chimney in any specialized store.

Ready passes are two types:

Passing unit C. finished insulation comprises:

Ready Ceiling knot with insulation

The adapter without insulation is metal boxes that are required to fill with insulating materials, and holes for pipes.

Node for arrangement of passage through the ceiling not having

How to install a pipe in a bath through the ceiling using the finished cutting? The whole process consists of the following steps:

1. to do a hole in the ceiling of the required size (depends on the requirements of fire safety and cutting dimensions);
2. in the right places, the cutting is insulated by the previously selected material;
3. the finished node is installed in the ceiling pass;
4. the tube is supplied to the ceiling in the bath. The length of the pipe must be less than a height of 10 - 15 cm;
5. the following section of the pipe is connected in the attic.
6. the joints of the pipes are sealed.

The process of installing the finished cutting

Arrangement of the ceiling transition with your own hands

For self-making node, the transition will be required:

• metal plates;
• insulation;
• chimney pipe.

The tube in the bath through the ceiling is installed according to the following scheme:

1. the ceiling is done by a hole, the diameter of which is more diameter of the furnace pipe used by 130 - 180 mm;

Additional strengthening ceiling beams

1. the chimney is displayed in the attic. In this case, the pipe connection must be higher or below the ceiling;
2. from the inside of the bath on the ceiling is installed metallic plate;

Mounting Metal Plate

1. all distance from the plate to the attic floor is isolated.

The pipe in the bath through the wall is paired in the same way.

The withdrawal of the smoke canal on the roof

Before bringing the pipe in the bath through the roof, you need to take care of two factors of the operation:

• select output location;
• purchase the necessary items.

Location for output

The pipe output through the roof of the bath can be made:

• on the ridge of the roof. This arrangement of the chimney is considered the most optimal, as snow and other precipitates do not accumulate in this place and good traction is ensured. However, in practice, this is not always feasible;

Skate

The rules for the arrangement of the chimney canal on the roof of the bath

Necessary elements

Installing the pipe into the bath through the roof is impossible without the following items:

• cutting, similar to the passage through the ceiling overlap;
• insulating material (compliance with safety rules);
• special apron protecting chimney from precipitation.

The cutting can be applied both ready-made and equipped independently.

Aprons can be:

• metal, providing a rigid adjustment of the structure to the roof surface;

Metal apron

Sheet with built-in apron

Pipe output instructions

How to remove the pipe in the bath through the roof? For this you need:

• do in the selected roof hole suitable size (slightly more disgraced pipe);
• around the hole hold strengthening work on the beams of overlapping;
• from the inner part of the roof, set the cut, as when moving through the ceiling;
• remove the pipe of the desired size;
• in the outer part of the roof, install apron.

The scheme of the arrangement of passage through the roof

Thus, knowing the rules of fire safety and instructions for the arrangement of the main nodes, the chimney for the bath can be mounted independently. To do this, you must purchase all the materials and the basic elements of the system. Before the first flooding oven requires time to dry out the sealants used (approximately 1 day) and checking the tightness of all shots of the chimney channel.

How the pipe for a bath through the roof

The output of the pipe in the bath through the ceiling is easier to implement using the finished passing unit, which can be purchased in the store. Pipe passage is carried out with the mandatory use of insulating materials.

Traditionally, metal furnaces are installed in the Russian bath for the normal operation of which it is necessary to properly plan and install the ceiling by the passage assembly for the functioning of the chimney. The principle of the device will depend on the degree of readiness of the ceiling, as well as from where it is necessary to remove the pipe - into the attic or attic, through the roof or on the second floor. For the level of compliance with the norms in relation to fire safety when the pipe is passed through the ceiling overlaps and the roof is responsible for the fiber of the chimney in the room of the bath.

How to equip a bantle room in the room or sauna

To equip the passage of the pipe through the ceiling in the bath is necessary to install the normally functioning and most importantly safe chimney system. It is impossible to skip this stage, since only in a specially equipped passage hole will be possible to install the pipe-transition from the pipe in the design of the furnace.

Hole B. stone wall Must be located strictly opposite the nozzle. Only in this case it will be possible to exclude the formation of the distillaces during the installation of the transition nozzle. For first, it is necessary to equip the hole correctly, the ceiling cutting is performed in compliance with the work algorithm described below.

You can enhance the hole using overhead plates with through holes. It is correct that the pipe is directed in a vertical position.

As for the plates, they can be made with their own hands from the finished iron sheet of the desired thickness.

CONSTRUCTION OF THE ROUND PIPE THROUGH THE CEILING BATTY WITH PPU of Different Type

The most convenient option in order to perform a chimney device of a wooden bath - the finished factory PPU for the chimney, taking into account the diameter of the pipe. Before mounting the node, the preparation of surfaces in contact with the wood trim, as well as the inside of the surface of the box, needing, requiring the correct thermal insulation.

When it is necessary to perform the installation of the factory type PPU, before starting work from all parties, with the exception of the facial insulating the insulator. The optimal solution is practical and environmentally friendly basalt wool with increased resistance to high temperatures. As part of such heat insulator binders, withstanding temperatures up to 1000 degrees. An additional advantage will be insulated with a foil cotton pipe to improve design safety during operation.

As soon as the diethrough the flue, the chimney will be correctly and securely, proceed to the preparation of the installation site:

1. To do this, mark the markup on the surface of the ceiling - at the location of the smoke tube.
2. The contours of the hole must be a bit leaving the parameters of the front panel of the node in order not to have arisen with fixation to the trim with self-drawing.
3. Over the contours, the hole is cut, the edges are isolated with the same insulator, which was used to protect the passage node.
4. To increase the level of security, the sheets are additionally used, but solid metal.
5. In the prepared hole, the ceiling-flow unit for the bath is mounted, while it is initially planted for convenience, after which the design is already fixed in a complete assembly.

The finished passage with the pipe is fixed with self-draws using pre-prepared holes.

Preparation and installation of ceiling penetration

Making sure that installing the pipe managed in the correct vertical position, go to the final operation. The voids formed in the passage node are tightly filled with material for thermal insulation - all the same basalt cotton wool ( the best wayWhen you need to arrange a reliable fireproof node PPU), or use clay.

As an option, it is worth considering and sand to fill emptiness, but with understanding that in relation thermal insulation properties It is noticeably inferior to basalt cotton and clamzit. In addition, as the grades are used, they will gradually turn down through the slots, penetrating into the oven and clogging it from the inside.

The subsequent algorithm of action will depend on the output of the chimney. Several ways of implementation are possible: installation of the pipe through the roof or chimney in the bath, on the second floor or the place of the attic. The main difference between the ways in the principle of finishing finish. So, if the chimney's withdrawal was initially performed on an attic or a roof, then the device for passing the above actions can be considered completed.

If you need to hold a pipe through the ceiling in the attic or on the second floor, you will need to take care of the aesthetic component - disguise the pipe with a protective metal screen fixed on the floor with the help of screws. Only after that it makes sense to move to the next stage - the output of the pipe through the base of the ceiling of the second floor, and then the roofs through the attic or the attic room.

CONSTRUCTION OF PIPE CONTACT without using factory pamp

You can remove the chimney outside and without a special passage design. In this case, the insulation of the edges of the holes with a material that is immune to high temperatures will be mandatory. If you follow the recommendations regarding the observance of fire standards, the distance from the pipe to ignited materials should not be less than 36 cm.

Making PPU with your own hands: Process features

It is important not to forget that the installation of the chimney should not resist the movement of the pipe, which in the bath under the influence of high temperatures will expand, requiring additional space.

From the side of the ceiling, the pipe is necessarily protected by non-combustible material, and from the second floor or the attic is filled with heat insulator, resistant to high temperatures. Most affordable option - Ceramzit. It is better for it with fireproof only basalt wool with a melting point of up to 1000 degrees and an additional foil layer.

Features of the passage for a brick chimney

Among the materials that have a long time to maintain a temperature, supporting a comfortable microclimate indoor, the brick rightly occupies one of the leading positions. When you need to properly equip the pipe for brick ovenThe main thing is what it is worth focusing - this is a special penetration device for thickening the chimney wall in the contact area with the ceiling.

If it is not possible to make a penetration possible, then a hole with a diameter is prepared in the surface of the ceiling base, slightly larger than the diameter of the chimney pipe, following the previously described algorithm for the device of penetration of a circular furnace through the ceiling:

• arrange protection for the edge of metal strips or minitis;
• conduct entrance from the dwelling by a metal sheet;
• fill emptiness in the attic area or the second floor with thermal insulation, resistant to high temperatures material;
• masked cutting on the side of the attic or the second floor with a metal sheet.

With this scheme of the passage device, you can be confident that the brick tube is reliably isolated and kept the aesthetic component.

Subtleties of the organization of a brick chimney through the roof

The main requirements for the aisle of the brick chimney through the roof - tightness and fire safety. To achieve efficiency on the second point in the contact zone of the chimney with flammable materials, it is important to track the temperature level, not allowing the thermometer to rise above 50 degrees Celsius. In case of brick structures This task is solved simply - by increasing the thickness of the walls with the device of special penetration and taking the inclination of the roof.

Making the passage of the brick tube through the roof of the bathroom, on each side it is strengthened by a special box.

An important point is compliance with the requirements for the distance between wooden elements and a pipe, it should not be more than 25 cm. If it is not possible to achieve the desired distance, the additional elements are mounted, thus minimizing damage to the waterproofing and thermal insulating layer upon subsequent output of the pipe on the roof.

During the chimney mounting it is placed in a separate box. Membranes and films inside it is cleaned carefully. In the corners, the film is cut at an angle, and the edges bend and fasten the brackets to the elements of the rafter system. To improve the sealing of the edge and cuts strengthen the adhesive tape. Not only the reliability and durability of the design will depend on the blesshood of work at this stage, but also the safety of the entire premises.

Another option should be considered in the case when the temperature of the pipe in the roof zone does not exceed 50 degrees. Only then can the edges of the diaper fix on the pipe with adhesive tapes and sealants, making special emphasis on the quality of sealing. Space between brick tube and rafters are layered resistant to moisture and high temperatures heat insulating materials, Including the basalt batted with a foil surface described above.

In conclusion, it remains to note that the principle of the device of the passage assembly through the ceiling to the second floor, the attic or through the roof is slightly different and depends on the material of the manufacture, diameter. The main condition for safe operation The stoves in the room of the bath will be the device for reliable thermal insulation of the passage at the base with resistant to high temperatures and open fire materials and compliance with the rules in relation to its tightness when the pipe is output.

Forumhouse users know well that high-quality installation of a metal chimney directly affects the safety of accommodation in the cottage. We have already written about. It's time to tell about the features of the installation of the steel chimney.

1. What is a sandwich chimney

Despite big choice Materials for mounting smoke systems, reliable steel sandwich chimneys have become the most widespread in private housekeeping.

The chimney of the type "Sandwich" is two pipes of different diameters inserted into each other, and all the free space between them is a place to fill the non-combustible insulation - mineral wool.

Mineral wool simultaneously plays the role of insulation and insulator.

Sandwich chimneys have the following main advantages:

• High speed mounting and low cost compared to brick chimns;
• The low weight of the smoke removal system;
• Smooth inner walls of chimney provide good traction and help reduce the formation of soot;
• The use of acid resistant varieties of stainless steel guarantees long term Chimney services.

The temperature of the exhausting smoke directly depends on the type of heating boiler and the type of fuel used. The higher the temperature of the outgoing flue gases, the stronger the pipe is heated and, accordingly, all constructive elementsThrough which it passes. Understand the dependence of the temperature of the smoke from the type of boiler and the type of fuel used will help the following table.

It should be remembered that the non-protected tree begins to be charred at a temperature of 200 ° C. Well dried wood can challenge from the open flame source at a temperature of 270-290 ° C. And if the wooden surface is subjected to constant heating more than 24 hours in a row, it may be self-splashing already At a temperature of 170 ° C. Therefore, when installing a sandwich chimney, it is important to comply with all fire safety measures. And any error made at this stage can lead to sad consequences - fire and loss of property.

Urban:

- My friends burned down two houses due to incorrectly mounted chimney sandwich. Moreover, in both cases, the fire occurred in the place where the yield of chimney is located through a wooden ceiling.

According to statistics, up to 80% of fires occur precisely due to incorrectly mounted chimneys. Therefore, when choosing and installing the chimney, it is necessary to adhere to SNiP 41-01-2003 "Heating, ventilation and air conditioning".

2. Chimney: distance to the slab of the overlap and the correct penetration

As practice shows, the greatest number of questions appears when calculating the distances from the chimney to the wooden floors.

VadimProro:

- Built a house, with a distance between rafters at 60 cm. And then it turned out that according to the existing standards, my chimney does not fit into this distance.

And again to the aid we come down:

vova230:

- According to the norms, when the penetration of wooden floors, it is necessary to withstand the distance of 38 cm from the inner tube of the sandwich to the combustible structures. All this space should be filled with a non-aggravated material. If the standard pass does not provide this distance, then the sizes of the furnace pass should be further increased.

If the chimney is paired through the protected wooden structures, then the distance can be reduced to 25 cm.

Protection of wooden structures - lag, ends of rafters, dohes - ensured due to the galvanized sheet with an asbestos-bearing cloth with a thickness of at least 5mm.

The galvanized performs the following functions:

• Prevents the spread of fire in the overlap;
• Ensures uniform heat dissipation;
• Screen and reflects the thermal radiation coming from the pipe.

In case of penetration inter overlap A single-tube steel chimney distance to any non-protected wooden structures should be at least 50 cm!

Also, the parameters of the chimney should be calculated in such a way that the chimney pipe passes through the entire overlap - without junctions with other elements. The chimney itself is installed through the duct-cutting pipe, which is a metal box.

Specialist from the portal site Alexey Teleginfrom Moscow recommends:

- According to the standards, the thickness of the cutting (box of metal) should exceed the thickness of the overlap by 7 cm.

Sealing overlaps at the point of passage metal pipes From the stove basalt-fibrous cardboard

Installation of PPU chimokhod

The process of installing the cutting in the wooden floors can be divided into a number of consecutive steps:

1. Cut the hole in the overlap of at least 700x700 mm.

2. If necessary, remove or enhance the beams of overlaps.

3. The perimeter of the carved outfit is sewn by non-splashable materials, superisole, etc.

4. For tightness under Superisole, we put a sheet of basaltokarton.

5. We make the carrying frame from the galvanized profile, which is used when installing HCL.

6. The sizes of the frame are calculated under the nodes of the attachment of the PPU (ceiling and passing unit).

7. We close the opening sheets of minit or superizole with a hole under the passage of the inside of the PPU.

8. Fix the PPU.

9. Install the sandwich tube.

10. He insulate the lower part of the PPU and the space around it the non-combustible insulation, this will avoid the freezing and education of the Inea and condensate.

The smoke removal system is better to lay and calculate even at the design stage of the house!

It is also important to pay attention to how the pipes are connected to each other. There are two ways - "by smoke" and "on condensate".

• The docking "on the smoke" - the tube of the lower knee of the sandwich enters inside the pipe of the top knee of the sandwich. In this case, the flue gases will be easily moving up through the walls of the pipe;
• Docking "According to condensate" - the inner tube of the sandwich: the top is inserted into the lower, the outer tube of the sandwich: the bottom is inserted into the upper one. With this installation, the pipe passes condensate, it is unhindered flowing down and does not flow over the outer part of the chimney, which can lead to fire.

Kotlaski:

- The condensate pipe is usually installed on modern gas boilers, because They have a low temperature of outgoing smoke.

W. metal stoves, cast-iron bourgeoque smoke temperature - about 300 ° C, which is released when burning firewood, begins to condense at a temperature of less than 100 ° C. At the time of the extracts of the couple, falling on the cold walls of the chimney, is deposited in the form of droplets of water, which are rolled along the smooth walls of the chimney down into the condensate collector.

Condensate collector is installed on the street. Sandwich chimney is better to collect "on condensate".

3. Features of the penetration through the roof

The penetration through the roof is made according to the same principles as the penetration through the overlaps. Let's find out whether it is properly that when there is a rafter, the distance to protected wooden structures can be reduced to size 150 mm.

Alexey Telegin:

- It is assumed that the chimney when the penetration is cooled through the roof, and the space around it is well ventilated, so you can reduce the gap to the protected rafters. In my opinion, this can be fair for the cold roof, and with the insulated, it is necessary to apply norms and distances as between interleaved floors.
