Today, we'll be discussing gas boiler burner faults and their troubleshooting methods. Let's take a look.
I. Gas Boiler Burner Ignition Electrode Fails to Ignite
Reasons:
1. Carbon deposits or oil stains between the ignition electrodes.
2. Cracked, damp, or leaking ignition electrodes.
3. Incorrect distance between the ignition electrodes (too long or too short).
4. Damaged insulation on the ignition electrode, causing a short circuit to ground.
5. Faulty ignition cable and transformer: broken cable, damaged connectors causing a short circuit during ignition; broken transformer or other malfunctions.
Troubleshooting measures include: cleaning, replacement, adjusting the distance, replacing the cable, and replacing the transformer.
II. Gas Boiler Ignition Electrode Sparks but Fails to Ignite
Reasons:
1. The cyclone disc ventilation gap is blocked by carbon deposits, resulting in poor ventilation.
2. The oil nozzle is dirty, blocked, or worn.
3. The damper setting angle is too small.
4. The distance between the ignition electrode tip and the leading edge of the oil nozzle is inappropriate (too protruding or recessed).
5. The first oil gun solenoid valve is blocked by debris (small flame oil gun).
6. The oil is too viscous and does not flow easily, or the filtration system is blocked, or the oil valve is not open, resulting in insufficient oil suction by the oil pump and low oil pressure.
7. The oil pump's own filter screen is blocked.
8. The oil contains too much water (boiling noise in the heater).
Troubleshooting measures include: cleaning; cleaning first, and replacing if necessary; adjusting the damper setting; adjusting the distance (3-4mm is ideal); disassembling and cleaning (cleaning the parts with diesel fuel); checking the pipeline and oil filter, and insulation equipment; removing the screws around the oil pump, carefully removing the outer cover and taking out the internal oil screen, and cleaning it with diesel fuel; trying with new oil.
