The smoke arrangement is responsible work, which is usually trusted by experienced specialists. The safety of the home of the house has depends on the quality of its implementation, as well as performance features Furnaces. Many owners are decided to fulfill this work independently. That's quite possible. But for this you will need to familiarize yourself with the basic rules for the arrangement of such a system. There are a number of nuances of holding how to make the flow of chimney through the roof, will be discussed in detail below.
Knot of the passage of the chimney through the roof Many are solved to equip themselves. This leads to different negative consequences. If the owners of the house do not know the subtleties of this process, they can refer to those skilled in the art. Their work requires additional costs. However, experienced builders will work well. Wanting to save, you need to learn all the nuances of this process.
If you bring the chimney through the roof incorrectly, moisture falls into the lesions. As a result, all materials from which the roof is made. IN carrier structures Mushrooms can appear and mold. They destroy overlaps and insulation materials. The microclimate in the house can be unhealthy. To extend the service life of the roof, you need to create sealed joints.
Wooden design elements need to be treated with antiseptics and antipirens. In some cases, the chimney can rest in a ram of the skate. It will require a deepening. On both sides, the timber is installed on the rack.
To create a swelling pass through the roof with your own hands, you need to mount a metal apron on the roof. It should be one of the edge to enter the surface of the chimney to the level of 30 cm, which protrudes over the level of the roof. The second edge is started under the roof material in the place where the cut was made. This option is suitable for those pipes that will take from the skate at a certain distance.
If the chimney goes close to the top bar, then the metal apron will need to be started under the ski element. On the pipe itself, the steel sheet must be started in the stroke. She is done in advance. It is fixed with the help of planks. Also, the entire system is thoroughly sealed with special insulating compositions.
If the width of the chimney from the side, which is located in parallel with the skate bruus, more than 80 cm, it will be necessary to make a flap. This situation occurs when the pipes from the furnace, fireplace, ventilation are combined in one pipe. To protect the joint between the pipe and the roof it is necessary to make a visor. It will divert water and snow to the sides. It is better to entrust this work to professionals, since in this case the master must have significant experience.
The flow of the chimney through the roof in the bath or in another structure can be sealed using a special adapter. It is used if chimney It has a round shape and made of ceramics or metal. The finished nodes to create a chimney pass on sale is a huge amount. Forms of similar products may be different. You can find nodes oval, round, square or rectangular configuration.
The choice of design variant depends on the material from which the roof coating and slinge system, as well as the diameter of the chimney, the angle of inclination of the skates. Also, the selection of the finished node affects the height of the attic space. Considate the material overlaps in the house.
Manufacturers produce passage structures that consist of 2 parts. These are metal rings and flanging. If such products are smelted from ferrous metals, the wall thickness should be from 1 to 3 mm. Rings consist of 2 contours. Each of them has isolation from basalt material. This eliminates the probability of fire in the presence of a heated tube.
The metal from which the transition unit is manufactured is covered by protective enamel. This avoids the development of corrosion. Enamel withstands the exposure to high temperatures (up to + 600ºС). Sometimes the penetration is made of stainless steel. The cost of such products will be an order of magnitude higher.
A knot of the passage of chimney through a soft roof or other materials can be universal. It is made of aluminum. The flange has a corrugation in the form of a cone made of silicone. There are several standard sizes of similar products. This allows you to choose a ready-made transitional unit for a pipe of the appropriate size. The top of the corrugations can be cut off so that the pipe can pass through her hole. At the same time, the flange is treated with a sealant. It is attached to the roof by self-draws. They are usually supplied complete.
If the roof is made of embossed materials that do not allow fixation using self-samples, you have to fix the system to the crate. For this apply long dowels. This, for example, may be required if the rollery is made of reinforced concrete. It should be noted that the type of roof material affects a large extent on the procedure for arranging the yield of the chimney.
From how the material is covered with roofing, the features of the recovery tube passage are dependent. Most often, the owners of the house are chosen to finish the rods ondulin, metal tile, professional flooring, etc. It is also often necessary to make the passage of chimney through a soft roof.
Sandwich chimneys have won a special popularity today. They differ simplicity of installation, high-quality design, durability and safety during operation. The outer housing of such a pipe is made of metal sheet. It has a beautiful shine. Such pipes almost always have a round shape. Therefore, for passing through the roof of the sandwich chimney, the finished passing elements are most often chosen. They are two types. Most often acquire elastic transitional structures. If the owners do not like how the brilliant tube with a similar design is combined, they can prefer a metal transitional node.
Elastic adapters are made from an elastic polymer, which is resistant to elevated temperatures. The flange (lower element) of the design is made of flexible material. Therefore, it can be easily installed on both smooth roofing rates and on the surface covered with metal tile with high waves. The passage through the roof of the sandwich chimney is correctly performed using this design it will be the easiest. Flaband fixation is made by self-drawing or special studs.
The advantage of elastic adapters for sandwich chimneys and other varieties of pipes is their low cost. In this case, the installation does not cause difficulties. Make a mistake in this case will be much more complicated. Completed in the kit detailed instructions Installation.
The joints of the joints during the installation is smeared with special heat-resistant sealant. They processes the place where the pipe comes from, as well as the joint between the flange and the roof. When the sealant gets up, you will need to screw the adapter with bolts. To do this, you need to drill holes in the lower flange ring.
Creating a passage of chimney through the roof from flexible tile Performed according to a specific technique. First you need to drill a sufficient hole in the roof. Through it will be displayed pipe. Often the roof does not have powerful beams for fixing the system. In this case, you need to purchase a collection pass. It consists of two parts. This reduces the load on the overlap.
Two prefab parts are attached using self-samples first from the inside of the roof. Outside it is necessary to glue with a conventional silicone special rubber material for creating a seal.
Next need to be installed non-combustible insulation. To do this, acquire mineral wool in rolls. With basalt or fiberglass fill the space between the prefabricular design and the chimney tube. During installation, you need to monitor the mineral wool to cover the rubber seal.
Complete with the precast passage comes the roof cutting. Its fixation occurs with the help of self-tapping screws. This option is ideal when creating a pass through the roof of the chimney from the sandwich tube. The roof cutting allows you to protect the system from water penetration. There are many varieties of such structures. They differ in the method of execution, material and angle of inclination.
As a rule, the slope of such structures is from 15 to 55º. The choice depends on the angle of inclination of the roof. If the material of its finishes are soft rolled varieties of materials, metal cutters can be applied. It is also quite suitable in this method of installation of structures that have self-adhesive lanto for high-quality adjoining system to the roof.
The flow of chimney through the roof can be done independently and if the coating is made of tiles. In this case, the chimney in most cases is plated brick. In this case, it will be necessary to perform work with special diligence. In this case, a corrugated, as well as self-adhesive leaf lead or aluminum can be applied to finishing the chimney pipe.
The listed materials are sold in the form of rolls. On the one hand, they are covered with a special adhesive composition. back side This sheet is covered with foil from listed metals. This design allows you to protect the chimney from mechanical damage, as well as to prevent water leakage after the rain or snowfall inside the house.
Another popular option when finishing the roof is Ondulin. It has a lot of positive qualities. It is sometimes called euroshipheral. It does not contain asbestos. Therefore, it is calculated to the category of environmentally friendly materials. However, its disadvantage is insufficient heat resistance. The temperature limit that this material may be subject to 110 ° C. Therefore, it is very responsible for the creation of passage through the roof. Make it quite difficult. However, in the presence of certain knowledge, even a beginner master will be able to cope with this task.
It is also worth saying that Ontulin not only does not withstand high temperatures, but can ignite. Therefore, for your own security, you need to know how to make a passage in the roof with a similar finish. It will be necessary to cut the opening in the roof much wider than the diameter of the pipe. The probability of leakage is increasing because of this.
To prevent negative consequences, Apply a metallic or silicone passage through the roof for the chimney. Be sure to mount the roof cutting. Also in the design necessarily there is a metal apron. The corner of the cutting is chosen in accordance with the position of the roof rod. The ends of the cutting during installation are administered to the nearby sheets of Ondulin.
If you want to create a swell of the chimney through the roof from the corrugated floor, most often the owners of the house acquire a sandwich tube. This is the most reliable, easy-to-install option. Professor combined with such a design perfect. To install the chimney make marking on roofing.
Next, with the help of the Bulgarian, it will be necessary to cut a hole. You need to retreat a few centimeters deep into the outlined circuit. The hole in this case will slightly decrease. This circumstance is necessarily taken into account when calculating the design. At the same time you need to be very careful. In the material should not appear Zzbinin.
When the hole is created, you need to make small slots in the corners of the hole. Thanks to this action, the material that the outer side of the skate can be drove up. Further, creating the flow of the chimney through the roof from the corrugated floor, it will be necessary to cut holes through the overlaps. The hole should be similar to the earlier earlier.
After that, it will be possible to mount a metal box. It additionally protects the roof from overheating. The sandwich tube is carried out through this box. Next, the space between the chimney and the roof material is put in a layer mineral wool. You can also pour clairzit. After that, a silicone seal is put on the pipe. It must be carefully glued to the professional floor.
Listed manipulations allow you to create a hermetic node. Water will not leak through it into the house.
The flow of the chimney through the roof from the metal tile is created using the standard external cutting. The pipe in this case is often made of bricks. First above the roof skate, you need to equip the inner apron. It must be mounted before the roof is covered with metal tile. Inner apron will need to be stroke. This element of the design is made of galvanized steel. The sheet may have a coating or do without it.
To make the flow of chimney through the roof from the metal tile, it will be necessary to apply the steel profile to the pipe wall. It marks the top edge of the apron. The grinding machine is made in the markup line. It is washed with water to remove the construction dust.
Installing an internal apron begins with its lower part. In the right places, the steel profile is cut. This item must be installed on the place intended for it. Next is its trimming. The apron is installed at the prepared place. It is tightly pressed to the base. The upper part at the same time should accurately coincide with the earlier shoe.
Next, the system is fixed by self-drawing. They are screwed through the bottom of the inside of the apron. They must pass through the wooden elements of the roof design. In the same way, the side and upper parts of the apron are assembled. They should be a minimum of 15 cm.
Having created the flow of chimney through the roof, which was covered with metal tile, you need to seal the inner apron. For this, the edge that was inserted into the stroke is treated with heat-resistant sealant.
Under the bottom edge, the apron starts a tie. it flat sheetdesigned for water drain. He is sent to Undov or down to the cornice itself. You need to make a side on the edge of the tie. This can be done with the help of pliers.
When the inner apron is installed, you can mount the outer protective screen. It is installed on the same principle as the inner apron. Only the upper edge will not be able to sleep in the stroke. It must seal the joint. For this, a special composition is applied, which is not afraid of high heating.
Having considered the features of the arouse the passage of the chimney through the roof, you can create a high-quality system with your own hands. Through it will not be selected water after snow or rain. The chimney will perform the tasks assigned to it correctly, will not be quickly covered with soot inside. Operation of furnace heating will be safe and efficient.
To avoid fires and protect yourself and their loved ones, you need to properly make the passage of pipes through the ceiling in the bath and perform all the necessary activities to prevent ignition of overlapping due to contact with a hot tube.
So it is very important to mount hot tube So that it does not in contact with the tree. For this, additional protection is being implemented from fireproof materials.
Below we look at the foundations fire safety, Types of materials, Installation technology and basic errors with a pipe passage through the overlap and roof.
Before proceeding with work, you need to get acquainted with Snip 41-01-2003 "Heating, ventilation and air conditioning". In the data construction standards normalized device heating and ventilation systems.
The text in the text indicates the distance from the outer surfaces of the pipes to the elements of the overlap and roof.
The distance from the roof elements to pipes must be additionally protected by materials that are not ignited.
Therefore, when creating a pass through the ceiling, the bath should be provided with a sufficient distance from the hot surface of the pipe to the overlap designs.
It is worth paying attention to the fact that during construction, many prefer metal pipes. Therefore, it is necessary to familiarize themselves with the annex K mentioned above, in which the minimum distances from the parts of the furnace and pipes are indicated:
|
Wall thickness oven, mm |
Departure |
Distance from the outer surface of the furnace or the chimney (pipes) to the wall or partition, mm |

Notes: 1 For walls with the limit of fire resistance Rei 60 or more and the limit of the flame propagation 0 cm The distance from the outer surface of the furnace or the smoke channel (pipes) to the wall of the partition is not normalized. 2 In the buildings of children's institutions, hostels and public catering enterprises, the fire resistance limit of the wall (partition) within the descendation should be ensured at least Rei 60. 3 The protection of the ceiling in accordance with 6.6.20, gender, walls and partitions - in accordance with 6.6.23, should be performed at a distance, at least 150 mm exceeding the oven dimensions. |

As you can see, the indent must be 500 mm to wood without thermal insulation and 380 mm to flammable materials with additional protection from fire.
In addition to the rules set out in SNiP 41-01-2003, you should carefully read the instructions for chimney from the manufacturer. The documentation contains information about the deposits taking into account the materials used.
During the heating of the furnace, the temperature reaches a critical mark, so wood can ignite from direct contact with the hot tube, which will lead to sad consequences.
To avoid a fire, you need to create an insulating layer of any non-flammable material. Excellent suitable for this:
If you want to carry out the initial cladding of the ends of the ceiling and have already spent exactly all the measurements and made indents, then you can also use weakly important materials, including:
Note! Savings on materials can lead to a fire and emergency, so in no case use standard mineral wool.
If you want to create an additional layer of chimney thermal insulation, then prefer basalt wad. It is not deformed and does not lose quality even at a temperature of 1000 degrees Celsius.
To protect the box with a pipe pass through the ceiling, basalt cardboard should be laid. To save, but not losing in quality, you can float the clay box.
Recove the ceiling from an elevated temperature on the box mounting section will help the metal sheet with sides with clay content (uniform distribution with a thickness of up to 2.5 cm).
Despite the existing solutions of pipes of the pipe through overlapping and roof, many today prefer to use safer pipes like "sandwich". The main difference between the sandwich from the ordinary pipe is a double tube with an additional layer for protection against elevated temperatures.
They are made of black or stainless steel and lead to a significant reduction in thermal radiation, the source of which is a gas feeding pipe.
It is worth noting that despite double wall, the external casing "Sandwich" also has pretty high temperature. Therefore, to ensure fire safety it is better to progress and apply recommended indents from combustible materials and thermal insulation materials to protect against the heating of the overlap at the point of passage of the pipe.
Inside the pipe during the caring of volatile compounds, the temperature can be very high. Therefore, during operation, it is impossible to violate the norms of the chimney device and the recommendations of the flue pipe producers on the device of the nodes through the overlap and the roof of the bath.
You can see the video device of the chimney from sandwich pipes below:
You need to adhere to two rules - mount the pipe exactly vertically and ensure reliable thermal insulation of overlapping using modern mineral heat-insulating materials. Therefore, you need to follow the following plan:
The following factors should be taken into account when applying a node.
After that, make a cut, but provide a minimum indent from all sides (decorative elements will hide it). Make a pass of the desired size You can with the help of an electric ·
If you have made a passage with your own hands, you can decorate it with galvanized iron or stainless steel. An additional plus of stainless and galvanized steel is that it is a good thermal screen.
Applying the ceiling and passing unit with a standard design from the manufacturer, stick the sizes that are listed in the instructions. If you create a pass from scratch, then thoroughly measure all distances required for the device of the passing box.
To calculate the distances, you can use the following formula: the inner diameter of the pipe is summed with two distances.
Note! It is much more preferable to calculate all the necessary sizes even at the stage of development of the Bani project. In the drawings, at the same time, it is necessary to note the optimal distance between the beams of overlapping and determine the exact size of the space required to mount the pipe.
If the passage of the pipe through the ceiling of the bath was not thought out at the stage of the project, then it is necessary to determine the location of the pipe and the passage node over the furnace.
Today, you can buy a ready-made alert, which is a metal structure installed in the balloting of the bath.
In terms of design and fastening strength, the factory design is much better self-made. In stores you will find any configuration of nodes for the passage of the pipe through the ceiling, which are a box of a rectangular or round cross section, securely bonded with a metal sheet that performs a protective and decoring function.
In the design of the factory ceiling passage node (PPU) there is already a cutout for the pipe, so that choose the node is needed, taking into account the diameter of the pipe.
To perform installation, follow the following sequence of actions:
1. It is performed by opening at the place of installation of the passage node and from the galvanized profile the frame of the ceiling assembly is collected:
2. Listov heat insulating material (asbetic sheet or basalt cardboard) carefully close the ceiling end at the location of the passage:
3. In places where the metal sheets of the passage assembly are in contact with combustible materials, also laid leaf insulation.
4. The design is installed in the passage hole in the ceiling and one knee of the sandwich is inserted into it, fixing in a metal structure, wrapping it asbestos cord.
5. In the upper part of the attic, the box is filling the box with refractory mineral wool, claying or other material recommended for use by the manufacturer.
6. After that, the attic part of the passage node can be closed with decorative metal elements.
If there was no store in your city, where you can buy a finished node of the overlap passage, it can be made independently. To perform work, you will need the following materials:
The first stage is the creation of a tin box. You can bend the sheet using a conventional board, with the edges of the edges followed by rivets.
In the buildings S. chimney heating, such as a private house, the bath and others, the structure of the smoke tube is required and the organization of its output is out. Camping Pipes through the roof, it is necessary to comply with certain norms to ensure safety and maintain the protective properties of the roof.
The chimney is designed to derive fuel combustion products (coal, gas, firewood, peat) and furnace traction. The way the pipe output through the roof is determined at the design stage. The main condition at the same time is to ensure the fire safety of the roof, especially on its junction with the pipe, as well as the protection of the joint from the atmospheric moisture and the accumulation of condensate. The height of the pipe is appointed by the standards of SNIP and depends on the distance on which it is from the ridge of the roof:
The height of the chimney pipe is determined by the standards of SNiP and depends on the distance to the ridge of the roof
The smaller the distance from the pipe to the skate, the greater the pipe height should be.
This element can be located in different places of the roof. One of the preferred options is considered to be the passage of the smoke pipe right through the horse. This method is characterized by the easiest installation and avoids the accumulation of snow over the pipe wall. The disadvantage of this location is to reduce the strength of the rafter system, in which the ski beam or is missing, or is cut and fixed by two supports on the sides of the pipe output, which is not always possible to implement.
The withdrawal of the chimney through the horse is different simple installationbut may interfere with the strength of the rafter system
Most often, the pipe is located near the skate. So the chimney is least exposed to the action of cold, and consequently, cluster inside the condensate. The disadvantage of this location will be the fact that the closer to the skate will be the pipe, the height should be more, and therefore the construction will require additional funds.
The withdrawal of chimney at a short distance from the skate is the most common and convenient option.
It is not recommended to carry out the chimney through Undova, since snow can accumulate in these places, which will lead to impaired waterproofing and leakage. In addition, at the junction of the skates it is difficult to organize a box of chimney. It is not necessary to place the chimney and at the bottom of the skate - it may be damaged by the snow from the roof.
The material from which the pipe is made also affects the organization of the system of its output. Usually pipes are made of metal, asbestos cement or refractory brick, but sometimes ceramic. Methods for their waterproofing will be different. In addition, each type of fuel has a certain combustion temperature, and this also needs to be taken into account when building a chimney.
Depending on the shape of the chimney pipe, the output hole can be square, round, oval or rectangular. To protect the root coating from the action of elevated temperatures and protect it from fire, a box is arranged around the chimney. This happens as follows:
The space of the box should not fill in fiberglass - it can ignite under the action of high temperatures
It is necessary to take into account that the construction of the box can disrupt the ventilation of the underground space, so you can install additional ventilation systems.
Equipping the passage of the chimney pipe, it is necessary to pay attention to the protection against atmospheric precipitation, which will be flushed along the pipe and roof. To moistureize the connection of the pipe and roof, a protective apron is arranged around the chimney. This technology is similar to roofs with different coating.
Metal tile - popular roofing material, which is thin steel, aluminum or copper sheets covered with a protective layer.
If the pipe is made of brick and has a square or a rectangle in cross section, it is possible to use materials included with the coating in a metal troop roof. As brick chimneys There may be non-standard sizes, in front of the output, part of the coating sheets is removed or the hole of the larger area is cut.
For the waterproofing of the joint, special elastic tapes with adhesive layer applied to one of the sides are used. One edge of the tape is glued to the base of the pipe, the other - on the roofing makeup. From above, the edge is fixed with a metal bar, which is attached to heat-resistant dowels to the pipe wall. All joints are wicked by sealant.
To reduce the likelihood of water pushing along the wall of the chimney, can be made under the plank - the stroke
An apron for a square or rectangular tube can be done with their own hands. It is made of a smooth metal sheet of the same color as the main coating. The top edge of the apron is refilled under the row of metal tiles, located above, so that the water flowing from above does not fall under it. If the pipe is located close to the skate, the edge of the apron can be fed under the horse or marit to the other side. To protect the passing hole from precipitation under the apron, a tie is installed.
The withdrawal of the chimney is better to organize before laying a metal tap.
When the chimney of the round section or the sandwich tubes, the roofing penetrations are most often used through metal troops, connected to the cap through which the pipe is performed. In the coating, a neat round hole in the size of the chimney is cut, a universal glass or master flush is worn onto the pipe, the joints are sealed.
For junction sealing round pipe and roofs use special peaks
The profiled sheet is one of the most common roofing materials. But it may occur in it, if it is incorrect to equip the yield of the chimney. Chimney with this form of coating is better to have vertically. The hole in the roof cuts through the grinder, while it is necessary to ensure that the cutting edge of the professional flooring is without jar.
If you need to organize a passage for a rectangular or square pipe, apron can be made of galvanized sheet.
Upper Plank Promotion to the Pipe Floats Sealant
When withdrawing the pipe of the circular cross section through a coating of a corrugated floor, a roll bituminous waterproofing or foil bituminous tape. It is put on the chimney roofingwhich passes on the cut and condenses the heat-resistant sealant. If the passage is made of rubber, it can melt from heating the pipe, so it is necessary to secure the clamp with a heat-resistant gasket.
If you use a roofing passage from heat-resistant rubber, you can avoid her melting
Ondulin is also called "erectifier". The peculiarity of such a coating is that it is flammable, and does not have great strength. Therefore, for the passage of the chimney pipe, you will need to make a hole in the roof. big size and fill it with fire-resistant material that will prevent moisture intake.
To water the chimney and roofing joint, set the metal roof cutting with apron, the edges of which are supplied under the sheets of Ondulin or use the elastic tape "Ondoflesh". Such a coating requires an additional ventilation device.
In the roof of Ondulin, it will take to make a hole for the withdrawal of a pipe of a larger diameter and fill it with fire-resistant material.
The soft roof is also a flammable material, so there is a gap of 13-25 mm between the coating and chimney. The waterproofing of the pipe is carried out in the same way as with other coatings, only instead of the elastic ribbon use an electrical carpet or coating the coating itself - bitumen tile or only.
When waterproofing the joint and soft roof Instead of elastic ribbon, the coating can be used
To bring out smoky pipe through finished roofThe following are necessary:
After installing the flange, the required form can be given to the hammer
The output of the chimney pipe through the roof is a responsible business, in which it is necessary to observe the compliance with the installation technology so that the danger of leaks and the destruction of the pipe does not arise. Work on the removal of the pipe includes many nuances taking into account roofing, material and shape of a pipe, waterproofing methods. Therefore, it should be studied in advance all stages of work and consult with a specialist.
According to experts, the most optimal option An smoking device is considered near the skate. Due to this, it will be possible to ensure the minimum accumulation of snow around the chimney pipe and completely eliminate the leakage in the adjustment zone.
In addition, the height of the chimney in this case is small, which leads to a decrease in the effect on the design of the device of negative external factors. According to construction regulations, the height of the chimney over the roof depends on the height of the smoke-sinking pipe.
It is not recommended to organize the passage of chimney pipe through the roof in such places:
For the correct and qualitative conclusion of the chimney, it is necessary to comply with the basic requirements of SNiP. Of course, some parts of the document could be outdated, however, according to its provisions, inspecting services will check you.
In which cases is required to pass the chimney through the roof? This may be required when erecting a new home or roof reconstruction. In addition, the rocking of the chimney through the roof is an indispensable part of the installation autonomous System Heating.
When erecting a new house you will know the type of roof used. It is possible that it will have to organize a complex conclusion when it is necessary to carry out a chimney through the roof covered with metal tiles or usually tiles. To date, it is easier to ensure the flow of the chimney through the sandwich-roof.
If we are talking about the usual reconstruction, then there is already a chimney and the place allotted for it. Of course, during the construction of a new house, it is much easier to arrange a chimney, as it is possible to see the kind of roof and place, where it is better to remove the chimney.
Deciding to bring the chimney to the roof with their own hands, remember that this is a very responsible business. The most important task is to create a good thrust. Otherwise, the efficiency of the chimney will fully depend on atmospheric phenomena: sometimes the furnace will work without problems, and sometimes smoke will go to the room itself, and not in the pipe.
But the most dangerous thing is that the error can cause fire.
In order to provide a device for a long period of use, the chimney should differ in good thermal insulation.
Such chimney will be less dependent on changes in air temperature, and most likely will not be subject to condensate.
If the roof is flat, then enough pipes with a height of 500 mm. If your home has a skating roof, then the length of the pipe will depend on the distance to the skate:
Inside the room, the chimney must be placed along the walls or partitions. The fixtures of the device must be performed in such a way that its horizontal sites do not exceed 1 m. In addition, the chimney should not be in contact with the electrical wiring and pipelines. Correct installation It starts from the boiler so that each pipe is included in the previous one. The joints are best bonded with a clamp. Ensuring the tightness of the joints is one of the most important tasks. For sealing, it is necessary to use a sealant that does not lose its properties even at a very high temperature.
Chimney pipes are made of different materials: refractory brick, metal or asbestos-cement pipe. The presence of a specific material requires a special construct of passage through the roof and different system Insulation. Also, the effect on the choice of design is the type of fuel in the fireplace or oven. The fact is that every type of fuel is distinguished by its combustion temperature, so first it is necessary to choose a fuel correctly.
If firewood or coal are used in the furnaces, it is forbidden to apply metal chimneys. To ensure better waterproofing, it is recommended to make chimneys of a square or rectangular shape.
Around the chimney is installed its own solo system. Warming materials should be chosen depending on the type of mineral wool. If the flow of the chimney is provided on the operated roof, it will be necessary to cut the waterproofing. To ensure maximum reliability, the place of attachment of the films must be subjected to additional sealing, mount the sealing tape.
That's all, now you know how to set the chimney through the roof. The passage is made, the pipe is bred on the roof, now it is necessary to take care that the roofing material fits tightly to the surface and missed water. For this purpose, a special design is applied - internal apron. Installing such apron involves the use of internal adjoining planks. Typically, the planks can buy along with other components.
