Gas Boiler manufacturer Said that a customer left a message saying that sometimes the burner malfunctions and they don't know what to do. Now I will give you a detailed explanation.
Connect the power supply, press Start, and the motor does not rotate: the air pressure is lack of locking; The solenoid valve is not tight, the connector leaks air, and it is locked through introspection; Open circuit of thermal relay; At least one of the conditional circuits is not valid (water level, pressure, temperature and whether the programmable controller can be powered on and started).
Method: Adjust the air pressure to the regular value; Clearing or repairing solenoid valve pipe joints; Press reset to check whether the components are damaged and the motor current; Check whether the water level, pressure and temperature can be limited.
After startup, the front purging is normal, but the ignition cannot be started: lack of electric and fire gas; The solenoid valve is not working (main valve, ignition valve); The solenoid valve is burnt out; Unstable air pressure; The air volume is too large.
Method: reflect on the line and repair it; Renewal; Adjust the air pressure to the regular value; Reduce air distribution and air valve opening
Ignition failure, normal air pressure, and electric failure: ignition transformer burned out; High voltage lines are damaged or scattered; If the clearance is too large or too small, the position of the ignition rod shall be of corresponding size; The electrode is broken or short circuited to the ground; The spacing is not appropriate.
Method: Renew; Re installation or replacement; Readjustment; Re installation or replacement; Adjust again.
Shut down 5s after ignition: air pressure is insufficient, pressure drop is too large, and air supply flow is too small; The air volume is too small, the extinguishment is not sufficient, and the smoke color is thick; The air volume is too large, presenting white gas.
Method: Adjust the air pressure again and clear the filter screen; Readjust
White smoke: the air volume is too small; The air humidity is too high; The exhaust gas temperature is low.
Method: Turn down the damper; Properly reduce the air volume and increase the air inlet temperature; Adopt measures to increase the exhaust gas temperature.
Chimney dripping: low ambient temperature; More small fires are extinguished; Fuel gas has high hydrogen content and high peroxide content, generating water; The chimney is long.
way: Gas Boiler factory home Reduce the air distribution; Reduce the height of chimney; Raise furnace temperature; When the exhaust gas temperature is low, the damper stops in the control mode, and the damper position switch signal does not reflect the sequence signal to check whether the damper wiring is loose or whether the switch fails.
