Inspection before igniting the gas boiler: 1. The boiler, fan, and boiler circulating water pump should be in good working condition. Safety accessories (such as pressure gauges, water level gauges, boiler explosion-proof doors, etc.) should be complete, flexible, and reliable. The water level in the hot water tank should be above 2/3 of the tank height (but below the overflow outlet). The boiler water level should be full. Keep the flue unobstructed and open the induced draft fan damper. Check whether the natural gas supply system can work normally (whether the gas pressure is normal, whether the gas-liquid separator is empty), open the gas manual valve, and ensure there are no leaks. Ignition start of the gas boiler: 1. Start the boiler induced draft fan and ventilate for 20 minutes. Press the start button to start the burner nozzle. First step: blow the furnace for 5 minutes. After 5 minutes, it will automatically ignite. Observe whether the ignition is successful. After success, run at low fire for one minute, then automatically switch to high fire, and then start the induced draft fan to operate normally. (Automatic program) 3. During operation, regular checks should be made every half hour, mainly checking the following points: a. Is the natural gas flow and pressure stable? b. Is the motor burner operating normally, and is there any noise in the motor? c. Is the furnace flame normal? d. Is the boiler hot water circulating pump normal (manual test)? e. Is the boiler pressure normal (normal pressure, adjustment range: high stop, low start)? f. Is the induced draft fan normal, and does the motor make any abnormal sounds? 4. During normal operation, the burner does not require any operation, and all fire size conversions will be automatically performed according to the settings. The burner has the function of manually switching to high fire and low fire, allowing for manual control of heat as needed. (Start-stop 2# fire protection switch) Stopping the gas boiler: 1. The furnace should be started and stopped regularly according to production requirements. Press the stop button to stop the burner and close the pipeline gas supply valve.
