Common faults and solutions of gas boiler burners

　　1. Connect the gas boiler to the power supply, press start, the motor does not rotate

　　cause of issue:

　　(1) Insufficient air lock;

　　(2) Insufficient solenoid valve, air leakage at the joint, check the lock;

　　(3) The thermal relay is open;

　　(4) At least one condition loop has not been established (water level, pressure, temperature and whether the program controller has been powered on).

　　Solution:

　　(1) Adjust the air pressure to the specified value.

　　(2) Clean or repair solenoid valve pipe joints;

　　(3) Press the reset button to check whether the component is damaged and the motor current;

　　(4) Check whether the water level, pressure, and temperature exceed the limits.

　　2. It is normal to start purging, but it will not catch fire

　　cause of issue:

　　(1) Insufficient electric fire gas;

　　(2) The solenoid valve does not work (main valve, ignition valve);

　　(3) The solenoid valve is burned out;

　　(4) The air pressure is unstable;

　　(5) Excessive air volume.

　　Investigation measures:

　　(1) Check the wiring and repair it;

　　(2) Replace with a new one;

　　(3) Adjust the air pressure to the specified value;

　　(4) Reduce air distribution and reduce the opening of the damper

　　3. No ignition, normal air pressure, no ignition when energized

　　cause of issue:

　　(1) The ignition transformer is burned out;

　　(2) The high-voltage line is damaged or dropped;

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

　　(4) The electrode is damaged or the ground is short-circuited;

　　(5) The distance is inappropriate.

　　Remedial measures:

　　(1) Renewal;

　　(2) Reinstall or replace;

　　(3) Readjust;

　　(4) Reinstall or replace;

　　(5) Readjust.

　　Turn off after 4, 5S

　　cause of issue:

　　(1) The air pressure is insufficient, the pressure drop is too large, and the air supply flow is low;

　　(2) The air volume is too small, the combustion is insufficient, and the smoke is thick;

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

　　Solution:

　　(1) Re-adjust the air pressure and clean the filter;

　　(2) Readjust;

　　(3) Readjust.
