Precautions for gas boiler installation

After purchasing a gas boiler, users also face the issues of transportation and installation. Ensuring the proper installation and operation of the boiler is a key concern for many users. Based on years of boiler installation experience, Zhongjie Special Installation has summarized the following precautions, hoping to help more users understand the correct operation methods when installing gas boilers.

 



 

1. The gas boiler must not be installed in a bedroom or room directly connected to a bedroom, nor in an air-tight basement.

2. To ensure safety and stability, users need to choose a professional installation company with gas boiler installation qualifications for installation.

3. The gas boiler power supply 220V needs to be connected to a reliable grounding wire to ensure safe use.

4. The connection between the gas pipe and the gas burner requires a gas-specific pipe.

5. After the gas pipe is installed, open the gas valve and use soapy water to check the connections for leaks. If there is a leak, close the valve, repair or replace the seals, and then check the gas boiler until there is no leakage.

6. Boiler installation must be level or reasonably planned, as short, few, and thick as possible, i.e., shorten the pipeline as much as possible, reduce bends, and use thicker pipes. In addition, the diameter of the return water main pipe should be the same as the diameter of the gas boiler outlet and return water outlet.

7. The slope of the natural circulation water main pipe and return pipe is 3-5%. The exhaust pipe should be placed at the system height and no valves should be installed.

8. The drain valve is installed at the lowest point of the system, and the bottom of the water tank should be higher than the water supply pipe. The active air vent valve must not be replaced with a vent, and the valve must not be installed or blocked.

9. When installing the flue pipe, it must extend outdoors, the slope should be inclined downwards by 5° to avoid condensation, causing corrosion of the furnace body, and no combustible materials can be placed around the flue pipe.
