If the gas burner doesn't catch fire, what should I do?

1. The burner has no gas: check the gas ventilation.

2. The solenoid valve or manual ball valve is not open: check whether the solenoid valve or manual ball valve is open.

3. Igniter does not produce spark: check whether the power supply is energized orwhether the igniter is damaged.

4. Incorrect position of spark or scattered spark: check whether the ceramic sleeve is broken,or adjust the distance between ignition electrode or ignition column.

5. The gas pressure is too high: adjust the pipeline pressure (5KPa is appropriate).

6. Intermittent spark or intermittent ignition: check the grounding of igniter
