⑤ White smoke at the startup time, black smoke,
or too much carbon deposition.Unplug the oil inlet
pipe, and start the heater to let it dry running till
the heater reporting fault. Repeat such operations
for 3-4 times.When no smoke out of the exhaust
pipe, connect the oil inlet pipe to start the heater to
see if the ignition is successful.
E2
Flame off (already
repeated 3 times)
① There are bubbles in the oil line and the oil
supply is discontinuous.
② Insufficient oil output of the fuel pump: Small
volume of fuel pump is used. Replace the
corresponding type of fuel pump.
③ Poor air intake and exhaust (generally, it will
cause carbon deposititions) Check the air intake
and exhaust to make the air duct smooth; It is
recommended to clean up the carbon carbon
deposition.
E3
Undervoltage or
overvoltage
① Confirm if the voltage of the power supply
matches the voltage of the heater.
② Poor power cord installation.
③ Access to additional non-compliant power cord.
④ Power converter can not provide enough
current.
⑤ Power converter output voltage is instable.
E4
Premature ignition
identification
The last illegal shutdown caused the heater to
ignite in advance with the residual fuel. Restart the
heater
E5
Open circuit or short
circuit of Temperature
sensor
① Small installation space caused overheat of the
heater.
② The temperature sensor of the circuit board is
damaged. Replace the circuit board
E6
Open circuit or short
circuit of fuel pump
① Poor contact betwen the wire harness and
socket of the pump. Reconnect them. ② Fuel pump
failure: Replace the fuel pump.
③ Control circuit board failure (rarely): Replace the
circuit board.
E7
Motor
① Motor fan blade is stuck: Reinstall the case of
the heater; it's damaged due to shipping.
② Defective motor: Replace the Motor.
③ Motor stall starts and stops for 3 times
continuously: Check if the Hall sensor on the circuit
board is bent or damaged.
④ Poor contact between the wire harness of motor
and the socket of control circuit board. Reconnect
them.
