Coaxial chimney: pipe and installation requirements, installation of a gas boiler, maximum length of the section

Coaxial chimney has a compact size and a small price In a wooden house, a self-contained heating system consisting of many elements was most often used. Their composition may vary depending on which coolant is chosen or how it will be heated. It should be noted that irrespective of the material used for the furnace, the boiler must have a smoke exhaust system or, in other words, a chimney. The design can have different configurations, features and even technical characteristics, however among many the most claimed is a coaxial chimney.

Advantages of coaxial pipe

Coaxial pipe for haovogo boiler - it's not just the product, and design has many advantages, due to which it has become so popular. High efficiency is ensured by perfectly heated incoming air.

Compact dimensions are typical, as it does not require the installation of 2 large pipes, but only one.

Coaxial chimney has a long service life and excellent appearance

No additional ventilation is required for the pipe. Environmental friendliness is extremely important for a person, as it is often possible to meet heavy and cheap materials that are capable of releasing toxic substances when heated.

Advantages:

1. Optimal cost of the product.
2. There is a possibility to solve the problem with the formation of condensate in the chimney, as it simply will not be.
3. Fuel consumption is reduced when it comes to a bath.
4. The chimney receives cold air, which prevents the chimney from overheating when the boiler is functioning.

This device, like a vertical smoke outlet of a coaxial type, is used for a heating system in which a gas boiler is installed, with a closed combustion chamber. The device for direct heating can be in the form of a gas boiler, convector or radiator. Installation of a double-circuit coaxial chimney must be carried out as correctly as possible so that the principle of operation is not violated. Each circuit is responsible for its specific task. The first is required for the withdrawal of combustion products from the cavity of the furnace in the boiler. The second one is intended for air inflow into the cavity of the furnace, which ensures effective combustion.

To ensure that there is excellent traction and uniform combustion of gas, a coaxial chimney should be installed in a boiler with a closed combustion chamber, the length of which does not exceed 2 m according to the rules. Otherwise, turbulence can form on the pipe, preventing the combustion products from escapingFirebox.

Coaxial type chimney: installation requirements

In order to install a heating boiler in which the combustion chamber is closed, an independent heating system must be installed, it can be used for individual construction, as well as in an apartment building or industrial premises. If a decision is made to install a coaxial chimney, it will be necessary to comply with certain rules and requirements, so that the device is carried out as correctly as possible and without oversights.

It is easy to install a coaxial chimney, therefore even a person without experience will cope with this

Requirements:

1. The maximum length of the coaxial chimney must be 2 m, but it is not uncommon to extend the distance if Ferolli is installed during installation. In this case, coaxial chimneys are used, the length of which is 4-5 m.
2. The pipe must be removed only using a horizontal method through a wall near which a gas boiler is installed. The length of this output section is 90-100 cm.
3. If there is a need to install a forced-type pull rod, then you should choose a fan, in which case you do not need to install the vertical part of the system.
4. The exhaust or outlet is located at a height of 2 m from the ground level, but the boiler must be not less than 1.5 m.
5. The place where the chimney outlet will be laid should be next to the wall, at a distance of 50 cm fromwindow.

It is not advisable to install a coaxial chimney under the window aperture, but if there is no other option, then there should be a distance of 1 m. To eliminate condensation, installation of a coaxial chimney and a slight slope of the pipe is required.

Co-axial boiler functions

A coaxial boiler, like everyone else, works to heat the room, but why is it called that?Coaxial boilers got their name due to installation of coaxial chimneys.

This chimney performs the following functions:

• Combustion products are output;
• The chimney design is very simple;
• The special feature is the installation of a pipe in the pipe.

Externally coaxial boiler is no different from other types

The internal cavity is responsible for the smoke output. Also air is supplied to the combustion device or, in other words, air mass is taken. Due to air, the boiler operates through the cavity of the outer pipe.

Stages of installation of a coaxial chimney

The chimney for a coaxial boiler must be installed, conforming to such provisions as the norms of SNIP, carefully thought out, qualitative and work properly. Coaxial chimney differs from the vertical and traditional device in that it is not difficult to install it, and it will not require a number of special skills or training, be sure to follow the instructions so that the installation technology is not broken. Only in this way can you be sure that the product is working properly and the penetration of smoke inside the room is categorically excluded.

Steps:

1. The connection in the first stage is to prepare the location for the future location of the boiler. Floor boilers should be installed on the footrests, and wall mounted on the surface of the outer wall.
2. The outlet openings on the chimney must be marked on the surface of the same wall near which the boiler will be installed, but only at a height of 1.5 m. The diameter of the location where the chimney is planned should be slightly larger than the pipe itself.
3. Requires the installation of a special connection element, through which the boiler and chimney will be installed. Each turn and joint of the pipe is fixed with a special fixing clamp.

It is strictly forbidden to install coaxial chimneys using adhesive tape or sealant. The hole in the wall space must be laid with a special incombustible heater.

For a coaxial chimney a small hole in the wall is needed

If the boiler is forced ventilation, then only the part of the chimney that is horizontal must be installed.

If it is necessary to make a turn in the pipe, you can use a special swivel knee, with a maximum of 2 knees per chimney. Installation of the pipeline on the wall surface is carried out with the help of brackets and so that they are necessarily present at each joint. At the end of the coaxial chimney it is undesirable to mount additional elements such as an umbrella, a deflector and others.

Maximum length of coaxial chimney for a gas boiler and the value of a chimney pipe

Depending on the model of the coaxial boiler, the length of the chimney is chosen, but an extension is possible, if this is permissible according to technical specifications. On average, the length can be 3 m. The coaxial type chimney has certain advantages, due to which its popularity increases almost every day.

Advantages are:

• Ease and speed of installation;
• Possibilities to use the product for any heating equipment;
• Excellent traction, provided that the installation is carried out correctly and strictly according to the technology;
• Opportunities to use a device for an apartment building.

Do not push the chimney far beyond the wall

Unfortunately, there are disadvantages of such products, but against the background of many advantages, they sometimes go to the background. To conduct the installation, it is necessary to coordinate the actions with sanitary and epidemiological surveillance. When the chimney is operating, a toxic condensate is released, which is prohibited from pouring into the ground, and is a direct pollution of the environment. Disposal of this condensate should be carried out in a separate location. If you install a design of such a two-channel type in a house with many apartments, then there may be outrage on the part of the inhabitants. If there is no appropriate permission from the organization, it will be required not only to remove the installation, but also to pay a fine. No matter how condensate is insulated, it will be too large, and a minimal disruption of the installation technology will lead to a number of problems.

What is a coaxial chimney( video)

Coaxial chimney is an excellent option for installation on pipes of flue gas discharge to a gas boiler, as compared to other facilities, it has a mass of positive sides and a long service life. The most important thing is to purchase high-quality equipment and properly perform the installation. Examples
