In order for the operation of gas heating equipment to be completely safe, it is necessary to organize the effective removal of all combustion products and the mandatory supply of fresh air to the working area of the boiler. In high-rise buildings, it is common to install floor-standing or wall-mounted boilers equipped with coaxial pipes http://www.teplodar.in.ua/dymohody/. They make it possible to solve all these problems, with the use of the most minimal costs for re-equipment of the premises in which the boilers are installed.
The composition of the coaxial chimney
The smoke exhaust system of gas boilers consists of the following components:
1. Coaxial pipe;
2. Revision device, installed for cleaning the chimney;
3. Condensate collector, it is created when smoke passes through the system;
4. Pipe extension, the length of the coaxial pipe should not be more than 3 meters;
5. If two devices are used, then installation of a tee is mandatory;
6. Elbows, used when connecting the pipe to the boiler, as well as for joining pipe sections;
7. Protective device that prevents the wind from blowing out the flame;
8. If the installation is carried out horizontally, then it is necessary to install an electric fan, which will contribute to the extraction of smoke.
Advantages of coaxial chimneys
These chimneys have unique operational characteristics and without problems create safe operating conditions for gas boilers and equipment in general.
These products are produced by a large number of companies.
The advantages of these chimneys include:
• The presence of a dual-circuit system capable of heating incoming air, which significantly reduces all costs and increases the efficiency of gas equipment. This indicator increases the air flow to the amount required for combustion.
• When installing a coaxial pipe, there are no problems. In order to install it, only one hole with a diameter of 200-250 mm is required.
• The outer surface does not heat up to high temperatures, this is a very important indicator in houses with wooden construction.
• Such pipes are sold in different sizes, which allows you to choose a pipe of the required diameter and for boilers of different power. For example, a 60/100 coaxial pipe can be installed on a boiler with a capacity of about 30 kW.
Installation Rules
The installation of these pipes is directly related to the gas equipment, for this reason the installation should be done by professionals.
When installing these pipes, certain technical requirements must be met:
• Laying of coaxial pipes can be done in different planes: inclined, horizontal and vertical. If a horizontal installation is performed, then there must be a slope of 3 degrees in the direction of the condensate collector. In addition, such a system must have a fan that will provide traction.
• Vertical installation of coaxial pipes is carried out if it is impossible to leave the necessary distance to windows, gas pipelines or other objects. Installation of coaxial pipes, thus, entails additional financial investments.
• The minimum height from the ground to the exit of the chimney, especially if the installation is carried out on the first floor, should be at least 1,5 meters. And above the level of the furnace, the chimney should be located at a height of 1 meter to 1,5 meters.
• When installing the pipe, additional elbows may be used, but no more than two.
• The distance between the window and the chimney should be 0,6 meters, and the distance to the gas lines is equal to half the diameter of the chimney.
When installing chimneys, there are a large number of requirements that only a chimney installation master knows about. And there are even more subtleties when installing condensate collectors and inspection devices. Therefore, for safe installation and further operation, you should contact professionals.
