Gas boiler ignition checks: 1. The boiler, fan, and boiler circulation pump should be in good working order. Safety accessories (such as pressure gauges, water level gauges, boiler explosion-proof doors, etc.) should be complete, flexible, and reliable. The hot water tank water level is higher than 2/3 of the tank height (but below the overflow port). The boiler water level is full. Keep the flue unobstructed and open the induced draft fan damper. Check if the natural gas supply system is working normally (whether the gas pressure is normal, whether the gas-liquid separator is drained), open the gas manual valve, and check for leaks. Gas boiler ignition start-up: 1. Start the boiler induced draft fan and ventilate for 20 minutes. Press the start button to start the burner nozzle. Step 1: Purge 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 run normally. (Automatic program) 3. During operation, regular checks should be carried out every half hour. The main checkpoints are: a. Whether the natural gas flow and pressure are stable. b. Whether the motor burner is running normally and whether there is noise in the motor. c. Is the furnace flame normal? d. Is the boiler hot water circulation pump working normally (manual test)? e. Is the boiler pressure normal (normal pressure, adjustment range: high fire shutdown, low fire startup)? f. Whether the induced draft fan is working normally and whether the motor is making abnormal sounds. 4. During normal operation, the burner does not require any operation, and all high and low fire switching will be automatically performed according to the set requirements. The burner has manual high fire and low fire switching buttons, which can manually control the heat as needed. (Start and stop 2# fire switch) Stopping the gas boiler: 1. The furnace is started and stopped regularly according to production requirements. Press the stop button to stop the burner and close the pipeline gas supply valve.
