Causes and solutions of gas burner failures of boiler

Causes and solutions of gas burner failures

Fault phenomenon

Causes

Suggested solutions

1. Turn on the power and press Start,
Motor does not rotate.

(1)Lockout due to insufficient air pressure

(1) Adjust the air pressure to the specified value

(2) The solenoid valve is not tight and the joints are leaking gas, check lock

(2) Clean or repair the solenoid valve pipeline
Connector

(3) Thermal relay open circuit

(3) Press reset to check whether the components are damaged bad as well as motor current.

(4) There is at least one conditional loop that is not established (water level, pressure, temperature and
and whether the program controller is powered on and started)

(4) Check water level, pressure and temperature
Whether it exceeds the limit

2. The front purge is normal after startup.
But can't light a fire

(1) Insufficient electric fire gas volume

(1) Check the line and repair it

(2) The solenoid valve does not work (main valve, point

(2) Renewal

(3) The solenoid valve is burned out

(3) Adjust the air pressure to the specified value

(4) Air pressure is unstable

(4) Reduce air distribution and reduce damper opening

(5)The air volume is too large

3. Can’t ignite, the air pressure is normal,
There is electricity, but no ignition

(1) The ignition transformer is burned out

(1) Renewal

(2) The high-voltage line is damaged or fallen off

(2) Reinstall or replace

(3) The gap is too large or too small, and the ignition rod position relative size

(3)Re-adjustment

(4) The electrode is broken or short-circuited to the ground

(4) Reinstall or replace

(5) The spacing is inappropriate

(5)Readjust

4. Turn off the flame after five seconds.

(1) The air pressure is insufficient and the pressure drop is too large. Air flow is too small.

(1) Readjust the air pressure and clean the filter

(2) The air volume is too small and combustion is insufficient. The smoke is thicker

(2)Re-adjustment

(3) The air volume is too large and white gas appears

(3)Re-adjustment
