Gas heating equipment of a private house requires an elaborate and assembled exhaust system of smoke and gas. Today, the chimney is not just a shiny pipe. Take it cooler! This is an entire structure, depending on the efficiency of the boiler and ensuring the safety of the heating system. Without exaggeration, we can say that a good boiler requires a good chimney and a pipe.

Rules for installing hoods and chimneys
There is no doubt that the assembled pipe for extracting the boiler, designed to divert combustion products (gas and smoke), is a constructive element of a complex system.
Having an idea of the main elements and the device of the chimney, you can be sure that the normal operation of the heating system will be ensured. The attention should be sharpened on the coordination of installation of elements of a drawing of a copper.
In addition, a good draft of the hood or chimney is the key to the effective use of combustion energy, and the convenience of the condensate collector design is the disposal of unnecessary problems. Therefore, the fitting densities of the mounting parts of the elements pay special attention.
Before starting installation and installation of the boiler pipe, it is recommended to select and justify the chimney variant.
Chimney hood options for gas boiler
There are several options for the device chimneys.
Recall that these are the following types:
- chimney brick
- stainless steel construction
- ceramic chimney
- presentable coaxial chimney.
Brick chimney is a complex and time-consuming construction of high cost. But over time, the hood for a boiler in a private house in the form of a brick pipe has lost its attractiveness and relevance to developers.
The design variant of a chimney made of stainless pipe, made in the form of a sandwich system, is of great interest, therefore more demanded and available for self-assembly. Selection of pipes for gas boilers from stainless steel provides a rich product lineup.
The ceramic chimney has not yet found its mass admirers.
However, this type of chimney can provide fire safety at an affordable price.
Presentability of the appearance of the coaxial chimney gives the impression that we are dealing with a solid "one-tube", which provides good performance indicators for heating gas systems.
Installation of any chimney design requires compliance with regulatory requirements SNiP 2.04.05-91and DBN В.2.5-20-200, ensuring the correct conduct of connections according to the typical drawing scheme of the boiler.
Gas boiler drawing device
The practical scheme and the drawing device of a gas boiler assumes the presence of the following elements:
- adapter connecting the gas boiler and the chimney pipe
- branch pipe
- telescopic pipes of different diameters
- wall fasteners (bracket and clamp)
- t-piece with revision to remove accumulated condensate
- taps and tips.
The installation procedure for a gas boiler of a wall or floor version is based on basic connection diagrams using standard 1/2 "and 3/4" nozzles. If you want to make a connection yourself, using the basic connection scheme.
How to connect a wall hood pipe
The basic scheme of connection and installation of the hood of a gas wall boiler consists of the following stages:
- mounting the boiler and fixing it to the brackets
- connection of the heating circuit
- connection to the HWS network
- connection to the gas main.
Gas boilers of wall and floor versions are equipped with a standard arrangement of nozzles (input and output), which allows to connect all the circuits: the main working, water supply and gas supply. The nozzle in the center is intended for connection to the gas main, on the left and on the right are the branch pipes for connecting the HPW.
To connect the flue duct (exhaust) to the main gas pipeline, a stainless steel corrugated hose is used.
Principles and types of installation of gas chimneys
Depending on the type of chimney passage, the exhaust pipe is provided with various seals, fittings and lining. The principle of installing the chimney exhaust is to create a trunk for laying the pipe, its installation and fixation, as well as sealing the place of docking with the wall or roof.
There are several types of installation of gas chimneys:
- horizontal passage through the wall
- vertical passage through the roof, roof and wall.
Designing the type of installation dictates the selection of equipment sets.
Structurally, the exhaust hood for extraction consists of elements:
- extension chimney in the inlet and outlet parts
- an intake chimney
- adapter for connection
- yoke of connecting
- of the knee.
All actions for the connection of corrugated pipes and hoses are made by installing inside the gasket and tightening the union nuts. The subsequent sealing of joints with thread sealers will ensure the reliability of the chimney.
The rules for laying the flue hood are shown in this video.
chimney coaxial horizontal passage
Installation of a coaxial chimney horizontal passage does not require special devices, it is enough to use the instructions and the delivery kit from the manufacturer. In most cases, the chimney and pipes are installed together with a heating boiler.
Kits of horizontal chimney passage through the wall, for example, coaxial Vaillant Series Turbo TEC (Pro / Plus) are designed for the collection and removal of combustion products outside the premises where the boiler is located.
The chimney kit includes:
- decorative cuffs for the design of the passage area
- extension section (length up to 800 mm) of pipe
- clamp connecting
- tap 90 °.
For turbocharged gas heating boilers, for example Protherm, there is a coaxial set of horizontal passage through the wall, consisting of:
- knee with flange
- plastic sockets (internal and external)
- exhaust pipe equipped with a grate
- air intake pipes
- connecting cuffs
- gaskets for flanges.
Stages of mounting the hood horizontal chimney:
Marking the hole on the wall, where it is planned to install a gas boiler
Punching hole for pipe mounting
Installing the connection element from the boiler to the chimney
Pipe laying
Fastening of joints and turns of pipes
Fastening the pipeline to the wall.
Vertical coaxial chimney is no less common option.
The installation kit of the vertical draft hood includes:
- section of pipe length more than 800 mm
- console with yoke
- flanges for roofing
- torch-head
- condensate collector
- cleaning device
The difficulty of installing the pipes of a vertical chimney will be the mandatory organization of penetration through the roof.
