If your heater fails to ignite, having air trapped in the fuel pump may be the cause. Air in the fuel pump will
cause ignition failure and is often accompanied by a loud "grinding" or vibrating sound being made by the
fuel pump. This heater is designed to easily remove any air in the fuel pump by simply following the Air
Bleeding Procedure below:
. Fill fuel tank with kerosene or No.  fuel oil. Turn the Air Vent Screw 3 full turns counterclockwise from the
factory closed / fully clockwise position. (This will allow air to escape during operation).
2. Start the ignition sequence by following the standard ignition procedures.
3. Allow the heater to attempt ignition for 3-5 seconds, during which time you may hear a loud "grinding" or
vibration sound.
4. If your heater has not ignited, re-start the ignition sequence. Once the heater has ignited, turn the Air Vent
Screw clockwise until fully hand tightened.
Any air trapped in the fuel pump will have been purged.
5. Your heater is now ready for operation.
6. Re-fill your heater with fuel before it runs out. This will prevent the fuel lines and fuel pump from drawing
in air and having to go through the air bleeding procedure again.
