Ten precautions for gas boiler installation

Gas boiler installation has many details that need attention, summarized in the installation of ten precautions:

1, in order to ensure the safety of use, the majority of users must choose a gas boiler installation qualification of professional installation company for installation.

2, gas boiler shall not be installed in the bedroom or the bedroom directly connected to the room, shall not be installed in the basement of the air is not clear.

3, gas boiler power supply using 220V / HZ AC power, must be connected to a reliable grounding wire to ensure the safety of use.

4, gas piping and gas burner links must be gas special tubing, links out of the non-use of hemp wire, must use raw material tape.

5, after the installation of gas piping, open the gas valve, with soap solution to check the connection section for leaks, such as leaks, close the valve to repair or replace the seals, and then check the gas boiler until there is no leakage.

6, boiler installation must be put flat or reasonable design, try to do short, less, thick, that is, try to shorten the pipeline, reduce the number of bends, pipe diameter should be thick. In addition, the main diameter of the water outlet and return should be the same as the gas boiler outlet and return pipe diameter.

7, the natural cycle of the main water pipe slope and the slope of the return pipe are 3-5%, there should be no wave, to prevent gas blockage in the pipeline, the piping system should be placed in the pipeline system at a high place, and shall not be added to the valve.

8, the system is installed at the low point of the sewage valve, the bottom of the water tank should be higher than the high point of the water supply pipe, the ventilation of the atmosphere shall not be replaced by automatic exhaust valve, shall not be installed valves, shall not be blocked.

9, gas boiler system piping is long, many bends, no slope, the heating effect is not good should be installed circulating pumps, pumps should be installed in the water supply pipeline, according to the heating area to choose the size of the pump.

10, the flue pipe must be installed to extend outdoors, the slope should be downward sloping 5 °, to prevent condensate channel flow, resulting in corrosion of the furnace, the flue pipe can not be placed around the combustible substances.
