FUEL FILTER
CLEAN TWICE PER HEATING SEASON OR AS NEEDED.
Fuel filter A on fuel cap
- Remove fuel cap.
- Take out fuel filter with clean
kerosene.
- Wash fuel filter with clean kerosene.
- Replace fuel filter on fuel tank.
- Replace fuel cap on fuel tank.
Fuel filter B on fuel line (See Figure 12)
- Remove fuel line A from fuel pump by using wrench.
- Take out fuel line from fuel tank by pulling out fuel filter gasket.
- Remove fuel filter assembly from fuel line
- Wash fuel filter in clean kerosene.
- Reassemble fuel filter in reverse order.
Use of diesel may require additional maintenance.
Improper
maintenance can lead to poor combustion and soot
production.
PUMP PRESSURE ADJUSTMENT
1. Remove right side panel.
(If not using an accessory fuel pressure gauge, please skip to #4)
2. Remove air vent screw.
3. Insert accessory fuel pressure gauge at outlet of air vent screw.
4. Adjust pump pressure by turning pressure adjusting screw. See
Figure 13.
5. Turn pressure adjusting screw clockwise to increase pressure.
6. Turn pressure adjusting screw counterclockwise to decrease
pressure.
7. Set pump pressure to 125 PSI (+/- 6PSI).
We recommend pump pressure adjusting is not needed
if red markings on pump body and pressure adjusting
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, page 7).
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. Service part# 70-071-0700.
AIR BLEED DIRECTIONS
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. 1 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). See Figure 14.
2 Start the ignition sequence by following the standard ignition
procedures outlined on page 6.
