First, the gas boiler burner ignition rod does not ignite
the reason:
1 The ignition rod gap is filled with carbon residue and oily.
2 The ignition rod is broken. Moist. Leakage.
3 The distance between the ignition rods is incorrect, too long or short.
4 The insulation of the ignition rod is damaged and short-circuited to the ground.
5 Ignition cable and transformer failure: 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: clear, replace, adjust distance, change line, and change transformer.
Second, the gas boiler ignition rod has sparks but does not catch fire.
the reason:
1 The ventilation gap of the cyclone is blocked by carbon deposits and the ventilation is poor.
2 The oil nozzle is dirty, clogged or worn.
3 The throttle setting angle is too small.
4 The tip of the ignition rod is not properly spaced from the leading edge of the oil nozzle (too protruding or retracted)
5 *The oil gun solenoid valve is blocked by debris (small fire oil gun).
6 The oil is too sticky and the flow is not easy or the filter system is blocked or the oil valve is not open, so that the oil pump is insufficient to suck oil and the oil pressure is low.
7 The filter of the oil pump itself is blocked.
8 The oil contains more water (the heater is boiling outside).
The treatment measures are: clear; first clean, if not change; small test; adjust distance (3~4mm is better); remove cleaning (clean parts with diesel); check pipeline and oil filter, heat preservation equipment Remove the peripheral screw of the oil pump, carefully remove the outer cover and take out the oil net inside, dip with diesel oil; try new oil.
Third, when the small fire of the gas boiler is normal and turns to a big fire, it is extinguished or flickering is unstable.
the reason:
1 The damper air volume of the big fire is set too large.
2 The oil valve micro switch of the big fire (the group outside the damper Zui) is not set properly (set to be larger than the damper of the big fire).
3 Oil viscosity is too high to be atomized (heavy oil).
4 The air ventilator is not properly spaced from the nipple.
5 The large oil nozzle is worn or dirty.
6 The heating temperature of the reserve tank is too high, causing the steam to make the oil pump misfeed.
7 The oil in the oil boiler contains water.
Treatment measures: gradually reduce the test; increase the heating temperature; adjust the distance (between 0 and 10 mm); clean or replace; set about 50 °C; change oil or drain.
Fourth, gas boiler burner noise increase
the reason:
1 The shut-off valve in the oil circuit is closed or the oil intake is insufficient, and the oil filter is blocked.
2 The inlet temperature is low, the viscosity is too high or the pump inlet temperature is too high.
3 The oil pump has failed.
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 works normally, and clean the filter net of the pump itself. 2 oil heating or lowering oil temperature. 3 Replace the oil pump. 4 Replace the motor or bearing. 5 Clean the fan impeller.
