Analysis of gas burner failure to ignite

  1. Analysis of the reasons why the gas burner cannot ignite:

1. There are carbon slag and oil stains in the gap between the ignition rods.

2. The ignition rod is broken, damp, and leaking.

3. The distance between the ignition rods is incorrect, too long or short.

4. The insulation skin of the ignition rod is damaged and short-circuited to the ground.

2. The ignition cable and transformer of the gas burner are faulty:

The cable is broken, the connector is damaged, causing a short circuit during ignition; the transformer is broken or other faults occur. 3. There are five treatment measures:

Cleaning, replacing, adjusting the distance, changing the line, and changing the transformer.

The reason why the gas boiler ignition rod has sparks but cannot ignite:

1. The ventilation gap of the cyclone disk of the gas burner is blocked by carbon deposits and the ventilation is poor.

2. The oil nozzle is unclean, blocked or worn.

3. The air door setting angle is too small.

4. The distance between the tip of the ignition rod and the front edge of the oil nozzle is inappropriate (too protruding or retracted).

5. The solenoid valve of the oil gun is blocked by debris (low-fire oil gun).

6. The oil is too viscous and difficult to flow or the filter system is blocked or the oil valve is not open, so that the oil pump does not absorb enough oil and the oil pressure is low.

7. The filter of the gas burner oil pump itself is blocked.

8. The oil contains a lot of water (boiling noise in the heater).

V. Treatment measures are:

1. Cleaning: clean first, if it doesn’t work, replace it with a new one;

2. Adjust the test: adjust the distance (3~4mm is better);

Remove and clean (clean the parts with diesel); check the pipeline and oil filter, insulation equipment;

Remove the outer screws of the oil pump, carefully remove the outer cover and take out the oil net inside, soak it with diesel; replace the new oil.
