The floor heating is natural and comfortable, and the radiator dissipates heat evenly and rapidly. In recent years, the floor heating and radiator are all powerful in the heating field and hot in the world. As the core equipment of the floor heating and radiator system, the gas-fired boiler has also become the focus of the majority of consumers.

Today, let's talk about the knowledge of gas boiler installation. There are many details needing attention in the installation of gas-fired boiler. Ten precautions for the installation of gas-fired boiler are summarized:

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

2. The gas-fired boiler shall not be installed in the bedroom or the room directly connected with the bedroom, or in the basement with poor air.

3. 220V / Hz AC power is used for gas-fired boiler, and reliable grounding conductor must be connected to ensure safe use.

4. The connection between the gas pipeline and the gas burner must be made of special gas pipes. Hemp wire shall not be used for the connection, and raw material belt must be used.

5. After the gas pipeline is installed, open the gas valve, use soap liquid to check whether there is air leakage at the connecting part. If there is air leakage, close the valve for maintenance or replace the seal, and then check the gas boiler until there is no leakage.

6. The boiler installation must be leveled or reasonably designed, and try to be short, few and thick, that is, try to shorten the pipeline, reduce bends and have a thick pipe diameter. The diameter of the main outlet and return water pipe shall be the same as that of the outlet and return water outlet of the gas-fired boiler.

7. The gradient of natural circulation water supply main pipeline and return pipeline shall be 3-5%, and there shall be no waves to prevent air blockage in the pipeline. The exhaust pipe in the pipeline system shall be placed at the highest point of the system, and valves shall not be installed.

8. A blowdown valve shall be installed at the lowest part of the system, and the bottom of the make-up water tank shall be higher than the highest point of the water supply pipe. The air outlet shall not be replaced by an automatic exhaust valve, and no valve shall be installed or blocked.

9. The gas-fired boiler system has long pipelines, many bends and no slope, and the heating effect is not good. The circulating pump should be installed. The water pump should be installed on the water supply pipeline, and the size of the water pump should be selected according to the heating area.

10. When installing the smoke pipe, it must extend out of the room, and the slope should be inclined downward by 5 °, so as to prevent the flow of condensation water channel and cause the corrosion of furnace body. Combustible substances cannot be placed around the smoke pipe.

The above is the general knowledge and precautions for the installation of gas-fired boilers. The floor heating and radiator system should not only install gas-fired boilers, but also install pipes, water collectors, end heat dissipation devices, etc. it is very complex, and users must choose a professional installation company.
