Many questions and problems arise at the moment when it is necessary to make a passage chimney through the wall.
Collapse
When designing this stage work should take into account a large number of factors, including:
- Wall structure;
- Materials used;
- Pipe exit location;
- Diameter of the chimney opening.
Diagram of the pipe exit from the furnace through the wall
Before you figure out how to remove the chimney through a wooden or concrete wall, you should carefully study the pipe outlet diagram from the furnace.
Below is a diagram of the output of a double-walled chimney through the wall:
Options for venting the chimney through the wall
What chimneys can be routed through the wall?
As building material usually black steel or alloy is used stainless steel, since this metal is most protected from destructive effects hazardous factors and smoke components.
DO NOT USE plastic or PVC pipes. The pipe will not be able to withstand the load, and may also be damaged during installation or exposure to environmental factors.
Calculations and installation rules
Installation rules imply careful consideration of all stages of future work:
- You should make sure that the pipe itself will not come into contact with any flammable materials, which, under the influence of high temperatures, may begin to smolder and release toxic fumes.
- When installing the system directly externally, it is necessary to remember the deflection angles, which will act as active guides for smoke removal. The chimney pipe should not be located parallel to the wall of the house, since in this case smoke stasis will occur - it simply will not be removed from the system.
- Special tees must be installed in the lower and side parts of the pipe, which will be used as a place to install mechanisms for condensate drainage. If this step is not completed, then moisture when lighting a fireplace or stove will simply enter the firebox and extinguish the flame. All this will significantly complicate the kindling process!
- The upper part of the pipe should rise above the edge of the roof to ensure that smoke and soot are blown away in an area of more rarefied air. Typically, such zones are formed at a distance of 15-25 cm from the roof sheet.
How to install a chimney?
The chimney installation process is divided into several main stages, which consist of:
- Preparatory work;
- Installation of fastening elements;
- The actual installation of the chimney.
General stages of work:
- Passage through concrete/brick wall. Concrete and brick walls represent the most convenient material that does not require additional processing. It is recommended to additionally putty the place where the hole was created in order to eliminate the possibility of rapid degradation of the wall of the room.
Passage through a wooden wall
When working with wooden surfaces should be carefully protected from overheating. Hot air passes through the pipe, which can cause materials to unintentionally ignite.
Ceramic mixtures that are heat-resistant are often used as insulating materials. insulating materials and even glass wool. You should not skimp on thermal insulation, as the consequences can be very sad!

Final work and system check
After completing all stages of work, you should carefully test the chimney to ensure that the manipulations were performed correctly. Before starting a test fire, you should place your hand in the firebox and make sure that there is air draft. In order to increase skin sensitivity, you can pre-moisten them in water.
If you feel a breath of air, you can light the flame. With a properly installed chimney, there will be no clouds of smoke or smoke in the room. bad smell. Modern systems Smoke and fume vents are designed to eliminate minor installation errors, so the system is more likely to function properly.
Advantages and Disadvantages
The main advantages of this method:
- less construction work,
- fewer building materials required,
- no need to deform several walls and surfaces of the house.
Despite the large number of positive aspects of this layout, it is worth remembering a large number of disadvantages:
- One of the main ones is the presence of a certain number of bends, which significantly slow down the speed of air flow, which negatively affects the draft in the furnace. Lack of traction can result in a decrease in combustion intensity, the formation of a mass of ash and incomplete combustion of the fuel.
- As a result of long-term operation of the furnace, sediment appears on the pipe, which must be cleaned. If a pipe is installed without bends, the process is simplified - not only chemical methods, but also mechanical, which consists of using a weighted weight. A stove with a chimney through the wall cannot be cleaned in this way. If there is a long-term lack of maintenance, it may even be necessary to dismantle the system to replace the chimney.
You need to weigh the pros and cons in advance to decide which option suits you best.
Conclusion
There is nothing complicated or problematic about bringing the pipe from the stove through the wall with your own hands. Understanding how a chimney works and carefully following the instructions will help you do all the work properly. Be sure that the result will not disappoint you!

The chimney is the most important component of the home heating system, ensuring the removal of combustion gases generated during the disposal of fuel put into the stove. In addition, with its help it is possible to avoid getting inside the room carbon monoxide and other elements hazardous to human health contained in the waste.
As a rule, the order in which these elements are arranged heating system laid during the design of the future structure and involves their internal or external installation.
When installing a chimney in an already constructed building, due to the complexity of its wiring through the roof, the channel outlet is provided through a hole in the wall. With this embodiment, the chimney itself will be located entirely or partially outside the building.
In this situation, it is necessary to have a clear idea of how to bring the chimney out through the wall in an already inhabited room.
Requirements for output channels and their types
Before installing a chimney, it is necessary to take into account a number of points regarding the permissibility of installation in a particular room. When wiring it through a wall, the following prerequisites must be met:
- Such a chimney is not allowed to be installed next to utility lines.
- Wiring through the wall should be done in an area where there are no joints between individual pipe blanks.
- The prepared hole must be protected with a protective casing, under which a heat-insulating gasket is placed in the gaps.
- The outlet pipe in the area where the chimney passes through the wall is rigidly fixed using special fasteners located at intervals of at least 60 cm.
- Horizontal sections when connecting to the wall should not exceed one meter in length.
According to their design, chimneys intended for outlet through the wall are divided into single-circuit and double-circuit systems.
A single-circuit design of the smoke exhaust channel is allowed when the chimney is placed externally in buildings made of non-combustible material (brick and concrete). Its main advantages are the relative ease of installation and low cost. The features of this method of arranging a chimney include the use of standard steel and stainless steel pipes.
When installing a double-circuit drain system, not one, but two pipe blanks inserted into another are used. Before the pipes are taken out from the furnace through the wall, a layer of insulating material is placed between them. This option for arranging a chimney passing through a wall has an increased degree of thermal protection and is recommended for use in wooden buildings.
Note
Constructions based on modern sandwich pipes, distinguished by their attractive appearance, relatively low weight and long service life, are becoming increasingly widespread in private construction.
It is clear that installing a chimney through a wall in wooden house involves its partial or complete laying with outside residential building. Let's look at the positive and negative aspects of this method of arranging the output channel.
Advantages of external installation of chimneys
The external method of wiring the outlet pipe has the following obvious advantages:
- Removing the main part of the drainage channel from the house allows you to increase the useful living space premises.
- The installation of a combustion product exhaust system can be carried out upon completion of the main construction activities.
- External gasket chimney removal will not require you to spend a lot of time and effort.
Easily removable disadvantages of this approach include:
- The need for mandatory insulation of chimney pipes.
- Possibility of significant heat loss with low quality thermal insulation.
- Difficulty of combination design chimney with architectural style buildings.
Despite all these difficulties, when deciding whether How make a chimney through the wall; preference is usually given to its external placement (full or partial).
Assembling the chimney and its outlet through the wall
Before we start installation work should be prepared complete set parts included in the structure being built. It should consist of the following standard components:
- a set of pipes and connecting elements (tees, in particular) necessary for branching the chimney and leading it out;
- so-called “elbows”, through which it is possible to form a bend in the pipe outlet at the desired angle (its value is usually indicated in the name of this workpiece);
- fastening support console, through which the structure is fixed to the walls (with a set of special clamps);
- a special inspection (inspection) tee, simultaneously used to clean the channel from soot;
- a moisture (condensate) collector built into the chimney.
If necessary, additional viewing windows and control valves are introduced into the structure.
Before installing a chimney through a wall, you should make sure that the angle of its connection to the wall is exactly 90 degrees (a pre-prepared angle can be used for these purposes). At the same time, you will need to take the dimensions of all the blanks and apply markings at the point where the pipe exits through the wall, specifying the location and diameter of the hole for it.
All further operations are carried out in the following sequence:
- First, in a wooden wall, in accordance with the markings, a round hole, corresponding to the diameter of the selected pipe blank (with a small margin for insulation).
- Then it is laid through it horizontal section outlet coming directly from the heating device.
- A layer of thermal insulation, optimally suited for the given conditions, is mounted on top of the outlet workpiece, and the hole itself is inside closed with a special protective casing.
The passage of a sandwich pipe through a wall is also subject to mandatory thermal insulation.
- The vertical part of the outlet channel is attached to the outside of the laid horizontal pipe at an angle of 90 degrees, the tees of which are fixed with support brackets, and the joints are secured with clamps.
- A condensation tank is mounted on the bottom side of the tee, and the main outlet channel is fixed on the wall using the same clamps and brackets, located at a distance of no more than 60 cm from one another.
Experts also advise organizing the insulation of the pipes being laid from the outer surface of the building walls (using basalt mineral insulation, For example). This technique is usually used when laying chimneys in buildings made of wood materials.
In conclusion, we note that users often ask the following question: how to remove the pipe from the bathhouse through the wall and are there any special requirements for this procedure?
The answer to this question is quite simple. In a bathhouse, the chimney outlet is arranged in exactly the same way, however, in this case, increased requirements are placed on its insulation, namely:
- the hole for the outlet channel is protected with special non-flammable materials (fire-retardant fabric, for example);
- In addition, this section of the wall is covered with metal sheets that protect wood material from excessive overheating and fire.
All other steps for laying a chimney in a bathhouse are similar to the operations already described earlier.
When designing wooden house It is important to consider how it will be heated. There are no problems when connecting to a centralized heating system. But if you decide to design a more economical autonomous method of heating rooms (boiler, stove), then you need to think about how to remove combustion products from the room. The main problem here is how to install a chimney through a wall in a private wooden house. To prevent unpleasant consequences, you must follow the recommendations for fire safety when designing and installing with your own hands.
Methods for making chimneys
Installation of the system by which combustion products are removed can be made from the following materials:
- brick;
- ceramics;
- metal.
A chimney in a wooden house made of brick is a solution that is now practically not used. The use is justified, for example, in the restoration process, when it is necessary to recreate the original appearance of a house that is of historical value.
Ceramic products are a more modern solution. It is a structure made of special chimney bricks, insulation and internal ceramic pipe. Their installation makes it possible to ensure the smoothness of the internal walls and reduce the deposition of soot on inner surface pipes.
A metal chimney is a composite pipe consisting of two shells with insulation laid between them. Each type of structure has its own installation and design requirements. Therefore, without a detailed consideration of each individually, it is difficult to understand the technology of the device through the wall.
Ceramic chimneys
When manufacturing an internal chimney, the following requirements are imposed on it:
Ceramic pipe installation - minimum distance from the chimney to load-bearing beams, if laying of asbestos sheets in two layers between the pipe and the ceiling is provided - 250 mm, without laying asbestos - 380 mm.
- if there is asbestos insulation, the distance from the pipe to wooden wall is taken to be 250 mm or more; if insulation is not provided, the distance is taken to be at least 380 mm.
- when using mineral wool for insulation, the distance from the pipe to the rafters is taken to be at least 130 mm;
- when using flammable materials - 260 mm;
- for roofing coverings in places of contact with the pipe, resistant to high temperatures materials (steel, ceramic tiles, slate). If materials such as bitumen are used flexible tiles, it is necessary to prevent its contact with the pipe. The distance from the bitumen coating to the chimney in plan should be at least 50 cm.
All the requirements described above are relevant for the manufacture of an internal chimney, but sometimes it is better to choose an external outlet. It avoids complications and increases the safety of the structure, since combustion products cannot enter the room.
Combustion products are immediately removed to the outside This installation is only suitable if the boiler is located directly on an external wall. The design will not allow for an extended horizontal section. The advantages of use include the attractive appearance of the building. This one is best option will do for boilers running on liquid and gaseous fuel. The disadvantage of the design will be advanced education condensate, which leads to the deposition of substances on the walls that destroy the pipe.
The external chimney is made in the same way as the internal one, but insulation of its walls in contact with cold air should be provided. The thickness of the thermal insulation is up to 10 cm and is assigned depending on climatic features terrain. It is important that in most cases the pipe will still pass through roofing, so it is worth following the recommendations for internal conclusions. A hole is provided in the lower part for inspection and cleaning, and a drip is installed. You will have to do it under a brick pipe separate foundation or a support projection under the house.
It is worth considering the following masonry requirements:
- providing dressing;
- production of ceramic solid bricks using lime (cement-lime) mortar inside the house;
- after exiting through the roof, the masonry is carried out using cement mortar;
- the thickness of the seams should not exceed 10 mm;
- Plastering the inner surface of the pipe is prohibited.
Metal chimneys
Here, during installation, in addition to taking into account the distance to secure the wall or ceiling, different thicknesses of the inner wall are taken to heating devices, from which combustion products are removed:
Smoke removal system through a sandwich pipe - boilers using gas, diesel fuel, pellets – 0.5 mm;
- fireplaces and stoves – 0.8 mm;
- coal boilers -1.0 mm.
The wall is made of stainless steel. An additional advantage of such a chimney is that it comes complete with elements to allow the chimney to pass through a wooden ceiling, roof or wall.
Installation through a wall fence eliminates the need to go through the ceiling and roof. This method increases the safety of the system, since the pipe is located outside and combustion products cannot enter the room. Ready-made parts are used to pass the metal pipe through the wall. At the same time, it is important to remember that a horizontal section appears and it is necessary to provide a sliding seal that will not damage the chimney during shrinkage of wooden structures.
Installation via outer wall metal pipes- the simplest option for making a chimney with your own hands. This method allows you to change the direction of the pipes without difficulty. The work is carried out in the following order:
- Marking the laying route, determining the exit point through the wall fence. Making a hole according to the dimensions of the chimney.
- Fixing the inside of the pipe, passing through a hole in the wall, insulation.
- Changing the direction of the chimney at an angle of 90 degrees using a special tee with a cleaning valve, which provides the possibility of inspection and cleaning. The device is installed at some distance from the wall.
- Increase the height of the pipe. If direction changes are required, additional tees are required. The chimney is fixed to the wall using special fasteners located every 2 meters.
Pipe thermal insulation
To bring the pipe outside with your own hands, it is necessary to provide for its insulation. The situation here is similar to insulating a chimney when passing through cold attic and after the output to the roof has been carried out. Installation of thermal insulation can be carried out using various materials.
Thermal insulation using mineral wool Mineral wool is easy to install and does not burn. There are special elements on the market for pipe insulation that will greatly facilitate the work. If you want to save money, it is better to choose glass wool in mats (rolls). Characterized by high efficiency. You can choose a material that is suitable in thickness and density.
Basalt pressed cardboard is a durable material that can withstand up to 2000 heating and cooling cycles. Basalt fiber does not burn. Positive aspects will also be low cost and able to withstand high temperatures.
Asbestos fabric is common in our country to meet fire regulations, but is not used in Western countries due to its carcinogen content. When used in external chimneys, human contact with asbestos is minimal, so the material does not pose a danger.
Installation of insulation for brick pipes is carried out in the same way as thermal insulation of external walls. For metal chimneys there are two options. The first is the simplest - buying sandwich type pipes. The design already includes insulation and consists of an outer and inner pipe. The second option is to make an outer casing from stainless steel and lay it between it and the chimney effective insulation. The easiest way in this case is to use mineral wool. The thickness of the thermal insulation is taken to be no more than 10 cm.
Installation of an external chimney is especially important when installing a boiler in an already used house, since it allows you not to affect the ceilings and roof.
One of the most important issues here there is sufficient insulation of the pipe.
There are times when it is not possible to remove the chimney pipe in the usual way - through the roof, and then you have to install a chimney through the wall. In order for the chimney to function as efficiently as possible, it is necessary to select the most suitable suitable pipes under the boiler, perform a high-quality installation of the chimney, and, if necessary, insulate it.
Brick chimneys, which were once very popular, are losing their relevance and are increasingly used today. These products are easy to install and inexpensive. Their surface is smooth; these pipes do not need to be insulated.
Advantages and disadvantages of a chimney through the wall
By venting the chimney through the wall you will get the following advantages:
- the chimney pipe almost completely protrudes onto the street, rather than passing through the entire house;
- You can install the product both at the construction stage and after the house has been built, for example, during the installation of a heating system;
- there is no need to make holes in the ceilings when the boiler is located on the ground floor of a building several floors high;
- the integrity of the roof is maintained;
- When assembling and installing a chimney through a wall, there will not be any particular difficulties.
Chimney through a wall in a wooden house
Despite the large number of advantages, the design also has disadvantages and they must be taken into account:
- A prerequisite for installing a chimney through a wall is.
- Inside or outside the house, you will need to allocate a fairly large horizontal area for such a chimney.
- According to experts, the external gas exhaust pipe has low productivity.
- It is unlikely that the product will fit the design of the room, so you will have to get confused here.
Installation of a chimney through the wall
Installation
Before proceeding directly to installation, it is necessary to carry out a number of preparatory activities, including calculating the boiler power, determining the optimal diameter of the pipes, as well as the thickness of the heat-insulating layer.
It is very important that the diameter of the inner pipe is not less than the diameter of the pipe on the boiler. The boiler is selected based on the criterion of the heated volume, and only after that the components for the chimney are selected for it.
If the diameter of the pipe is larger than the diameter of the pipe, then an adapter must be placed in the middle of them.
When installing pipes of a certain diameter, it is necessary to take into account the power indicators of the heating device. So, for boilers with a power of up to 3.5 kW, the diameter of the pipes should be 8 cm, for equipment with a power of 3.5 to 5.2 kW, pipes with a diameter of 9-11 cm are needed, for products with a power of 5.2 kW - The diameter of the pipes must be greater than 11 cm.
It is also necessary to take into account the thickness thermal insulation layer. When working temperature conditions 250°С, same as gas boiler, the basalt layer must be at least 3 cm.
For wood and liquid fuel boilers with operating temperature 400°C – already 5 cm.
Installation of a chimney
There are two ways to exit the chimney through the wall:
- The pipes inside the room must be raised a short distance from the ceiling, where they are brought outside.
- From the boiler nozzle, pipes lead immediately through the wall in a horizontal position. The advantage of this method is that fewer bends are formed, and this has a positive effect on the performance of the chimney.
Assembling a sandwich pipe when installing the vertical part of a chimney can be done in two variations - “smoke” or “condensate”.
Assembling a chimney “for smoke” and “for condensate”
When installing a pipe along the smoke, gas and combustion products move upward, but here you will have to deal with such a negative aspect as the formation of condensate that accumulates in the pipe. This method has gained popularity in cases where the chimney is assembled through the roof. Here, almost the entire pipe is located in the house, and not much condensate is formed.
Condensate installation is an installation method in which the pipe with its expanded end is directed upward.
With this assembly, the condensate simply flows through the pipe into the glass. The disadvantage of this method is that smoke can leak out if the areas at the joints are poorly sealed.
Condensate collection is used when a chimney passes through a wall: in this case, the condensate is directed into a glass, and the smoke comes out of the joints on the street. This will not affect the well-being and health of the residents of the house.
Basic installation rules
In order for the functioning of the chimney to be as efficient as possible, during the installation process it is necessary to follow a number of rules and recommendations on which not only the performance of the installation will depend, but also safety.
Basic requirements for installing a chimney through a wall:
- It is important that the pipe rises above the ridge by at least 50 cm, and preferably 100 cm. The traction force depends on this. The traction force directly depends on this.
- The total length of the vertical part of the pipe should ideally be 5-10 meters; if the pipe is located at a greater distance, the draft will be too strong and the fuel will burn out very quickly. If the pipe length is not enough, then the draft, on the contrary, will be weak, and, accordingly, the operation of the heating device will not be very efficient.
- To prevent the heat insulator from melting, the first segment of the chimney must consist of a single-circuit pipe. It is necessary to make a joint with a sandwich pipe, while maintaining a distance sufficient to ensure that the fastener does not overheat during operation.
- The boiler must be placed on a metal sheet. Insulating the wall from the boiler is done in the same way. For wooden houses, according to SNiP, it is necessary that the boiler and chimney be located at a distance of at least 45 cm from building elements that can catch fire, and 25 cm from parts made of low-flammable materials. To ensure that the outlet hole for the pipe is not too large, the wood must be sheathed with metal, in which case the outlet hole may be 25 cm rather than 45 cm.
- A metal box must be placed in the finished hole through which the pipe is passed, without any connections, because if necessary, access to them will be very difficult. The cavities in the wall must be filled with heat-insulating material that is not afraid of burning.
- Next, you need to sew up the pipe hole from the outside and inside. A metal sheet is used for this.
- Then, using brackets, you need to fix the support platform for the chimney outside the building, and a tee should be placed on the outlet section of the pipe. The bottom of the pipe is removable, it has the shape of a glass and condensate, which is formed during the combustion of fuel, gets into it. Often the glass is equipped with a tap and a drainage hose. Condensation is a toxic substance, so it is better to drain it away from home.
- The chimney at the top is also secured using brackets, which are located one from the other at a distance of no more than a meter. To protect against precipitation, a cap is placed on top of the pipe.
- To properly seal the joints, they must be coated with heat-resistant sealant, after which the joint area must be tightened with a clamp.
Insulation of external chimney
As already noted, the most best option chimney is the use of a sandwich pipe, which is not only easy to install, it also does not require additional insulation.
If it is used for smoke removal, then you need to install it in a box, where the distance between the walls of the box and the pipe is filled with a basalt heat insulator. You can also use foil or other non-flammable material as insulation, but the top of the pipe must be covered with a dense layer of heat-insulating non-flammable material.
To summarize all of the above, it is worth saying that installing a chimney through a wall is quite simple. If you strictly follow the installation technology, this procedure will not take much time and effort, and the heating device will delight you with its operating efficiency and good traction.
Sandwich pipes are becoming increasingly popular products used in the construction of chimneys. This is due to their at an affordable price, long term operation, as well as attractive appearance. A big plus is the possibility self-installation similar chimney despite some nuances. For an amateur builder, the whole process can take no more than 2-3 days, provided that the work is carried out according to a ready-made drawing.
You should remember several basic points that must be observed when installing a chimney:
Having familiarized yourself with the above rules, you can install sandwich chimneys through the wall in accordance with all established standards. A design that performs its functions can ensure efficient and safe operation.
“By condensation” or “by smoke”
As you know, a sandwich pipe has one side wider, the other slightly narrower. The modules are connected due to the difference in their diameters. Turning the wide end up (see figure) means “condensate” assembly, which involves liquid droplets flowing down.
Insufficiently tight sealing of joints can lead to smoke leakage through microcracks, which is a disadvantage of this method. This type of installation of a sandwich chimney through a wall is used quite often, since it requires condensate to drain down. The leakage of smoke into the street in this situation is not at all critical.
When turning the narrower edge upward, another element is put on it with a wide part. Such an assembly is called “by smoke” (see figure). With this installation method, condensation can leak through a poorly processed joint. In this case, the smoke passes through unhindered. This type of assembly is used when the pipe is located indoors and is discharged through the roof.
The unpresentable appearance of condensate flowing down a cylindrical product compensates for the safety that is ensured by complete removal flue gases into the surrounding space. In addition, high-quality sealing of all joints does not allow condensation to leak out.
For a more reliable connection of the modules in the sandwich system, a heat-resistant sealant is used, then everything is tightened with a clamp.
Brick or concrete wall
Exiting a chimney pipe through a structure with walls made of brick or concrete is not a difficult task, especially since such materials are not flammable substances. Correct pipe output involves the following stages of work:
When erecting a brick chimney, the distance between the structure and the wall is reduced to a minimum, thereby giving it greater stability. This requires correct calculation external and internal parameters. The slightest error can lead to overheating of the walls or other serious consequences. The lower part of the structure is usually equipped with a compartment for collecting condensate. When connecting a brick channel and a heating device, pipes made of stainless steel are used.
Wood wall
Installing a chimney through a wooden vertical enclosing structure is similar to the method described above, but requires certain precautions:
Installing a deflector will completely relieve you of problems associated with poor traction. Such equipment looks like a special umbrella, which is mounted on the top of the pipe. The function of the deflector is to increase the pressure drop. Some models are able to independently turn in the wind and pull the entire flow of smoke in their direction.
This method of pipe assembly is relevant for both a bathhouse and a garage. Before installing a chimney through a wall, all calculations must be carefully completed. In addition, you should not skimp on quality materials, since the life of you and your loved ones depends on the strength of the structure.
Advantages and disadvantages of pipe outlet through the wall
A chimney located in a horizontal plane has many pros and cons. The positive points include the following:
- Competent execution of a wooden house project allows you to fit the chimney into its overall design.
- Saving space in the room, since the external location of the channel preserves the internal volume of the house.
- Easy to assemble and install, unlike traditional technology installation through the upper structure of the building. Exiting the pipe through the wall prevents damage to the integrity of the floors between the floors of the building and/or its roof.
Among the negative points, the following are noted:
- The need to insulate the external walls of the chimney.
- The external location of the channel requires the installation of a horizontal section underneath it.
- According to experts, the external gas exhaust pipe has low efficiency.
- Certain difficulties arise when combining the design of the structure with the exterior of the structure.
Safety regulations
The likelihood of a significant increase in pressure in the channel involves closing the joints with specially designed couplings. Joints on steel pipes It is advisable to seal with heat-resistant sealants. Complete insulation of the chimney promotes proper draft.
Sandwich panels with good thermal insulation characteristics, do not exclude the possibility of overheating, and possibly ignition of those located near chimney materials. To prevent this situation, it is recommended to increase the layer of thermal insulation at the joints of the structure.
If you follow the main safety rules, installing a chimney will not be difficult. In addition, it is necessary to ensure high-quality maintenance of the canal, including its regular cleaning. This will become a kind of prevention of accidents during operation of the furnace.
Conclusion
Chimney location in load-bearing wall is the simplest and budget option. Absence of work related to violation of the integrity of the roof and interfloor ceilings, speeds up the channel installation process.
It is important to choose the right design parameters and qualitatively connect all the elements, since even small flaws made during the assembly of the system can make its operation ineffective, and in some situations even dangerous.
