Pipes for gas columns: exhaust and exhaust pipes for gas columns

In the installation work associated with the installation of the gas column, much attention should be paid to removing the combustion products formedat work of such equipment. This is important not only for the safety of people who use a heater, but also for the economical and efficient operation of the device.

When choosing the exhaust gas removal option from the column, it is necessary to take into account:

• The place where the column will stand.
• Model of the device.
• Required chimney height.
• The required diameter of the exhaust pipes.
• Column power.
• Climatic conditions in which the equipment will operate.

At present, the exhaust system for a gas column can be mounted using:

1. Corrugated pipes made of multi-layer thin aluminum. Such pipes are flexible and can change their length.
2. Steel pipe. To protect them from corrosion, such pipes are treated with heat-resistant enamel. When installing in a private house, this type of pipes should be insulated.
3. Double-circuit pipes. They are a "pipe in a pipe" construction, while between the outer and inner pipe there is a thermal insulation( mineral wool).In such a pipe, condensation does not form.
4. Coaxial tube. In their design, the inner pipe removes the exhaust gas from the column to the street, and between the walls of the outer and inner tubes air from the street is fed to the burner. Columns with this type of exhaust system are called turbines, since the venting of gases in them is carried out with the help of a fan.

Work should be started from the column by connecting its outlet pipe to the vent hole in the wall. Further, the chimney is mounted on the outer wall of the building or inside the house. The pipe sections are fixed with brackets. Once the vertical part of the chimney is installed, mount the headlining and leave the inspection window. In conclusion, check the thrust.

The problems with the exhaust gases are associated with:

• Incorrect installation of the chimney.
• Poor-quality materials.
• Insufficient thermal insulation of the structure.
• Leaks of connections.

In the next video you can see what errors are more often allowed when choosing chimneys and how to choose them correctly.

Typically, for the operation of a column with an open combustion chamber in a city apartment, there is enough natural ventilation in the room, which is provided by the presence of a window in the room and not a clogged ventilation shaft. At the same time, many column owners are thinking about the additional installation of hoods in order to increase safety and increase traction. In fact, if the draft is sufficient, there is no need for such actions. On the contrary, installing the hood above the column can lead to such problems:

• If there is insufficient air flow into the room( for example, if the window is closed), the hood will take air from the ventilation shaft of the bathroom, which will lead to an unpleasant smell in the kitchen.
• If the ventilation duct is one and there is already a hood in the room above the stove, the additional installation of the hood will create a return draft, which is dangerous for the health of the occupants.
