If you decide to install a wall-mounted gas boiler at home or in the country, remember that this process is very complicated, and the technology depends on the type and technical characteristics of the device. Gas boilers can be single-circuit (heating) and double-circuit (heating and hot water supply), atmospheric and turbocharged. Below we will tell you how to install a double-circuit wall-mounted gas boiler.
First, you need to remove the plugs installed by the manufacturer on the nozzles, then connect the boiler to the hot water pipes. For this, sealing gaskets are inserted into the connecting parts of the pipeline, which are tightly tightened with nuts..
If you have purchased a boiler with a natural exhaust of combustion products, then check the cleanliness of the chimney before installing the chimney. If the chimney is not clean enough, soot particles can subsequently obstruct the escape of combustion products, which is potentially very dangerous. The pipe connecting the chimney and the boiler must be resistant to high temperatures, wear and the effects of combustion products. The length of the connecting section between the boiler and the pipe should not be more than two pipe diameters, and the pipe itself should be inclined, and its length should not exceed 2500 mm. Wall-mounted gas boilers with forced exhaust of combustion products do not need a separate chimney, since combustion products are removed from the room into a coaxial chimney through the outer wall of the building or into a collective chimney.
There are several important points to consider when installing this type of equipment. The fan compartment must be free of foreign matter. The pipe for air intake and exhaust of combustion products must be located at a height of at least 2200 mm from the ground and protrude from the outer wall by at least 18 mm. Any equipment above the pipe should be at a distance of more than 25 cm, and it is recommended to seal up the space between the wall and the pipe so that rainwater does not get there..
Regardless of the model of the gas boiler chosen, notify the gas supplying organization about the future installation and arrange for a specialist to come who will conduct a test run of the equipment. Ideally ask a professional for help with installation.
When buying a boiler, check that all the necessary materials and instructions are available, check its serviceability, compare the data on the identification plate and packaging, specify the type of gas with which the boiler works.
The gas boiler is connected to a separate electrical wiring, which has a circuit breaker and a voltage stabilizer. There must be at least 800 mm between the floor and the boiler, at least 500 mm between the walls and the ceiling from the side and top.
Use a soap solution to check the tightness of the connections. Hissing and bubbling will indicate a gas leak..
