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:
1. 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).

7. Set pump pressure to 25 PSI (+/- 6PSI).
We recommend pump pressure adjusting is not needed if red markings on pump body and pressure adjust-
ing screw are aligned with each other.
NOTE: Use only original equipment replacement parts. Use of alternate or third party components will void any warranty and
may cause unsafe operating conditions.
8. Stop heater (See OPERATION in this manual).
9. If accessory pressure gauge is being used, remove pressure gauge.
10.
Replace pressure gauge, and plug in end of filter cover.
NOTE: If heater does not ignite when heater is turned on, please turn AIR VENT SCREW counter clockwise to release air, then
turn OpERATION SWITCh back on.
NOTE: An accessory service fuel pressure gauge is available for accurate fuel pressure testing.

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.
