NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
MAINTENANCE AND STORAGE
WARNING:
To prevent personal injury, unplug the heater from the
wall outlet before servicing.
For maximum efficiency and trouble-free service, make the following
periodic maintenance, cleaning and inspections.
ADJUSTING PUMP PRESSURE
Due to varying fuel viscosities and normal component wear the pump
pressure on this heater may need to be adjusted.
Pressure Adjustment Screw (located at the rear of the heater)
ADJUSTMENT PROCEDURE:
1. Fill fuel tank.
2. Start heater.
3. Locate the fuel pressure adjustment screw (ref. #46) in the exploded
parts drawing (pg.9). The pressure adjustment screw is located at
the rear of the heater, in the air filter housing cover (approx. 2" from
the left side and 1" from the top).
4. Using a flat bladed screw driver, turn the pump pressure adjustment
screw clockwise to increase pump pressure and/or counter-
clockwise to decrease pump pressure. Base pump pressures can
be found in the specifications chart on page 3 of the "Operating
Instructions and Owner's Manual".
5. For best results, the nose cone in the combustion chamber should
be cherry red with no dark spots and the flame should not extend
beyond the nose cone.
IMPROPER PRESSURE ADJUSTMENT
Problem:
Heater does not have a strong consistent flame.
Heater smokes and spits raw fuel.
Nose cone does not get cherry red.
Adjustment:
Pump pressure is too low.
Turn adjustment screw clockwise to increase pump
pressure.
Problem:
Flame extends beyond the end of the heater.
Adjustment:
Pump pressure is too high.
Turn adjustment screw counter clockwise to decrease
pump pressure

DAILY SCHEDULE
1. GENERAL. Make general visual inspection of heater for loose or
damaged parts. Check nuts and bolts to insure against looseness
caused by vibration or rough handling. Damaged parts should
be repaired or replaced before using heater again. Check heater
operation to be sure it is operating normally (See "Servicing" section
for description of normal operation).
2. FILTERS. Dirty air or fuel filters will cause an imbalance in the air-fuel
mixture. The best indication that this condition exists is an increase
in odors or difficulty getting your heater to ignite. This heater should
never be operated without the filters in place. If required, clean
filters as described under "500 Hours" and "Annual" Schedules.
500 HOUR SCHEDULE
1. AIR INTAKE FILTER. Remove and wash the filter element with a mild
detergent, dry thoroughly and replace. Do not oil the filter element.
If your heater is used where there is considerable dust or dirt, clean
as often as necessary (approximately every 50 hrs.).
2. REMOVE DUST. Clean heater twice a season (more often under
dusty conditions). Remove accumulated dust from the transformer,
burner, motor and fan blades with compressed air. Safety glasses
should be worn when using compressed air. Wipe area clean with
a clean dry cloth. Inspect area to ensure all foreign materials are
removed, especially around the burner and combustion area.
3. CAD CELL. Clean the glass portion of the cad cell with a soft dry
cloth.
4. NOZZLE. Accumulation of dirt from fuel and carbon from the
compressor vanes will eventually fill up the passages in the nozzle,
resulting in reduction of fuel and air flow. Pressure will gradually
increase giving improper fuel-air mixture and excess odor and
smoke. If this occurs, replace the fuel nozzle.
5. FUEL TANK. Clean twice a season (during frequently used periods,
clean twice a month). Drain and flush the fuel tank with clean fuel
oil.
ANNUAL SCHEDULE
1. AIR OUTPUT FILTER. Remove the air output filter and tap the
contaminated side gently on a solid object to remove contaminates.
Compressed air or liquids should not be used to clean this filter.
Reinstall cleaned filter in filter body in the same position as it was
when removed. If the filter appears extremely dirty, replace it with a
new filter of the same type. When replacing the filter cover, be sure
the gasket is firmly in place and the screws in the filter cover are
tight to prevent air leaks.
2. FUEL FILTER. Remove the fuel filter from fuel line and direct
compressed air through the filter in the opposite direction of fuel
flow. Safety glasses should be worn when using compressed air.
3. AIR AND FUEL LINES. If the air or fuel lines are removed during
cleaning, be sure all connections are tight before operating unit.
STORAGE
Store the heater in a dry location free from fumes or dust.
At the end of each heating season, clean the heater as described in the
MAINTENANCE section. Drain and flush the fuel tank with clean fuel.
The manufacturer recommends completely filling the tank with fuel for
extended storage to minimize condensation inside the tank.
SERVICING
WARNING:
A hazardous condition may result if a heater is used that
has been modified or is not functioning properly.
When the heater is working normally:
* The flame is contained within the heater.
* The flame is essentially yellow.
* There is no strong disagreeable odor, eye burning or other physical
discomfort.
* There is no smoke or soot internal or external to the heater.
* There are no unplanned or unexplained shutdowns of the heater.
