1, switch on the power, press start, motor does not turntoyBoiler Burner

 toyBoiler Burner

(1) air pressure is not enough to lock (2) the solenoid valve is not strict, the joint leakage, check the lock (3) thermal relay open (4) condition loop at least one is not valid (water level, pressure, temperature and whether the program controller is energized to start)toyBoiler Burner

 toyBoiler Burner

(1) adjust the air pressure to the specified value (2) clean or repair the solenoid valve pipe joint (3) check whether the component is damaged and the motor current (4) check whether the water level, pressure and temperature exceed the limittoyBoiler Burner

 toyBoiler Burner

2. After starting, the front purge is normal, but the ignition cannot be startedtoyBoiler Burner

 toyBoiler Burner

(1) electric fire air quantity is insufficient (2) the solenoid valve does not work (main valve, ignition valve) (3) the solenoid valve burns out (4) the pressure is unstable (5) the air volume is too largetoyBoiler Burner

 toyBoiler Burner

(1) check the circuit and repair it (2) replace it (3) adjust the air pressure to the specified value (4) reduce the air distribution and reduce the valve openingtoyBoiler Burner

 toyBoiler Burner

3, the point is not on fire, normal pressure, electricity is not to firetoyBoiler Burner

 toyBoiler Burner

(1) the ignition transformer is burned out (2) the high voltage wire is damaged or falls off (3) the gap is too large or too small, the relative size of the ignition rod position (4) the electrode is broken or short circuit with the ground (5) the spacing is not appropriatetoyBoiler Burner

 toyBoiler Burner

(1) replace with a new one (2) re-install or replace with a new one (3) re-adjust (4) re-install or replace with a new one (5) re-adjusttoyBoiler Burner

 toyBoiler Burner

5. After ignition, the fire will be extinguishedtoyBoiler Burner

 toyBoiler Burner

(1) air pressure is insufficient, pressure drop is too large, gas supply flow is too small (2) air volume is too small, combustion is not sufficient, smoke is thicker (3) air volume is too large, white gas appearstoyBoiler Burner

 toyBoiler Burner

(1) readjust the air pressure, clean the filter (2) readjust (30 readjusttoyBoiler Burner

 toyBoiler Burner

5. White smoketoyBoiler Burner

 toyBoiler Burner

(1) the air volume is too small (2) the air humidity is too high (3) the exhaust temperature is lowtoyBoiler Burner

 toyBoiler Burner

(1) reduce the damper (2) appropriately reduce the air volume, increase the inlet temperature (3) take measures to increase the exhaust temperaturetoyBoiler Burner

 toyBoiler Burner

The chimney drips watertoyBoiler Burner

 toyBoiler Burner

(1) the ambient temperature is lower (2) the combustion process of small fire is more (3) the gas contains more hydrogen, and the amount of oxygen to generate water (4) the chimney is longer (5) the temperature of smoke discharge is lowertoyBoiler Burner

 toyBoiler Burner

(1) reduce the air distribution volume (2) reduce the chimney height (3) increase the furnace temperaturetoyBoiler Burner

7. The burner motor does not worktoyBoiler Burner

 toyBoiler Burner

(1) no voltage (2) fuse damage (3) motor failure (4) control circuit interruption (5) gas transmission interruption (6) control failure (7) contactor not working (8) thermal relay damagetoyBoiler Burner

 toyBoiler Burner

(1) connect the circuit (2) replace (3) repair (4) find the disconnect point, contact or disconnect the regulator or monitor (5) open the ball valve, in the case of insufficient gas quantity for a long time, notify the gas management agency (6) replace (7) manual reset check (8) replace the thermal relaytoyBoiler Burner

 toyBoiler Burner

(1) air pressure switch failure (2) pressure switch pollution, pipe block (3) electromagnetic valve is not sealedtoyBoiler Burner

 toyBoiler Burner

(1) replacement (2) cleaning (3) exclude the case of not sealingtoyBoiler Burner

 toyBoiler Burner

9. The burner motor runs, but stops in the pre-purge state after 10 secondstoyBoiler Burner

 toyBoiler Burner

(1) pressure switch contact is not connected to the operating position (air pressure is too low) (2) the blower is contaminated, thermal follow-up action (3) the rotation direction of the burner motor is wrongtoyBoiler Burner

 toyBoiler Burner

(1) correct adjustment of the pressure switch, if necessary, to replace (2) cleaningtoyBoiler Burner

10. The burner motor runs, and the voltage is applied to the terminal post 16 of the controller. There is no ignitiontoyBoiler Burner

 toyBoiler Burner

(1) the ignition electrode is too far away (2) it is contaminated (3) the ignition electrode or circuit grounding (4) the ignition transformer failstoyBoiler Burner

 toyBoiler Burner

(1) adjust electrode spacing (2) clean (3) remove grounding, replace damaged electrode or cable (4) replace ignition transformertoyBoiler Burner
