Cause of issue: Flame temperature is lower than the minimum ignition temperature

Solution:

  • Check whether there is fuel inside the tank. If not, please refueling.
  • Check whether the fuel tube is blocked and whether the connection is intact, if not, please repair or replace it.
  • Check whether the fuel is condensed. If so, please replace the fuel suitable for the environment
  • Check whether the exhaust pipe is blocked. If so, please clean it up.

Please check whether there is sufficient fuel in the tank. If not, please add fuel.

  • If the air intake is blocked, and whether there will be white smoke coming out.
  • If there is much black smoke coming out, the air-let is blocked during heating. Please clean it regularly.
  • If you find it troublesome to clean the air intake regularly, you can just take it off.

Please check whether there is fuel leakage of the fuel tank, and the black rubber fuel hose is aging.

Please check whether the fuel pipe is blocked, and each pipe/hose connection is well. If so please clean or change a new one.

  • Please check whether the fuel filter leaks. (Put it into the water. Bubbling means it’s broken.)
    Check whether the fuel is condensed. If so, please replace the fuel suitable for the environment
  • Please check whether there is Impurity in the fuel, which makes the fuel pump blocked. If so, please clean the fuel pump and change the fuel.
  • Newly received heater, check whether there is air tubing. Disconnect the fuel pipe with heater, and let the fuel pump automatically pump oil.

When the fuel is full and coming out from pipe, connect the fuel pipe into the heater

Error code E07: 

Cause of issue: Power supply voltage is too high

Solution:

Use the multimeter to check the voltage power. If it’s lower than DC 20V, please charge the battery or use a new one; if it’s higher than DC 30V, please use a new battery.

  • Use the multimeter to check the power voltage:
  • 24V: If the voltage is higher than DC 30v;
  • 12V: If the voltage is higher than DC 15v
  • Please change a new power.
  • Or maybe you bought a heater with wrong model.
