1. Reasons why the ignition rod of the gas boiler burner does not ignite:
1. There are carbon residues and oil stains in the gap between the ignition rods.
2. The ignition rod is broken. wet. Leakage.
3. The distance between the ignition rods is wrong, too long or short.
4. The insulating skin of the ignition rod is damaged, and it is short-circuited to the ground.
5. The ignition cable and transformer are faulty: the cable is disconnected, the connector is damaged, causing a short circuit during ignition; the transformer is disconnected or other faults occur.
There are five types of treatment measures: clearing, replacing, adjusting distance, changing wires, and changing transformers.
Second, the ignition rod of the gas boiler has a spark but cannot ignite the reason:
1. The ventilation gap of the cyclone disk is blocked by carbon deposits, and the ventilation is poor.
2. The oil nozzle is dirty, clogged or worn.
3. The damper setting angle is too small.
4. The distance between the tip of the ignition rod and the front edge of the oil nozzle is not appropriate (too protruding or retracted)
5. The solenoid valve of the first oil gun is blocked by debris (small fire oil gun).
6. The oil is too viscous to flow easily or the filter system is blocked or the oil valve is not opened, so that the oil pump does not absorb enough oil and the oil pressure is low.
7. The filter screen of the oil pump itself is blocked.
8. The oil contains more water (abnormal sound of boiling in the heater).
The treatment measures include: clearing; cleaning first, if it doesn’t work, replace it with a new one; reducing the test; adjusting the distance (preferably 3~4mm); dismantling and cleaning (clean the parts with diesel oil); check the pipeline and oil filter, heat preservation equipment ;Remove the peripheral screws of the oil pump, carefully remove the outer cover and take out the oil net inside, soak it with diesel oil; try it with new oil.
3. When the small fire of the gas boiler is normal and turns to a high fire, the reasons for extinguishing or flickering are unstable:
1. The air volume setting of the fire damper is too large.
2. The oil valve micro switch of the high fire (the outermost group of the damper) is not set properly (the air volume is set to be larger than the air volume of the damper of the high fire).
3. The viscosity of the oil is too high and it is not easy to atomize (heavy oil).
4. The distance between the cyclone disc and the oil nozzle is improper.
5. The oil nozzle of the large fire is worn or dirty.
6. The heating temperature of the reserve oil tank is too high, causing the steam to make the oil pumping difficult.
7. The oil in the oil-fired boiler contains water.
Treatment measures: gradually reduce the test; increase the heating temperature; adjust the distance (between 0 and 10mm); clean or replace; set it to about 50°C; change oil or drain water.
Fourth, the reasons for the increase in the noise of the gas boiler burner:
1. The stop valve in the oil circuit is closed or the oil intake is insufficient, and the oil filter is blocked.
2. The oil inlet temperature is low, the viscosity is too high or the oil inlet temperature of the pump is too high.
3. The oil pump is faulty.
4. The fan motor bearing is damaged.
5. The fan impeller is too dirty.
Treatment method: ① Check whether the valve in the oil pipeline is open, whether the oil filter is working normally, and clean the filter screen of the pump itself. ②Heating or lowering the oil temperature. ③Replace the oil pump. ④Replace the motor or bearing. ⑤Clean the fan impeller.
