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.
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. Wipe area clean with a clean dry cloth. Inspect area to
insure 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.
4.
AIR PRESSURE SETTING. The air pressure has been properly

set at the factory. If the air pressure is out of adjustment, it
will most likely be caused by dirty air filters, a partially
plugged nozzle, an air leak in the system or improperly set
pressure. If adjustment becomes necessary, first determine
the proper pressure setting for your heater which is printed
on the serial label located on the fuel tank. With a full fuel
tank, remove the plug (part #33 from the exploded-view
drawing on page 9) from the air filter cover and attach a 0 -
15 PSI pressure guage. Start the heater and note the
pressure reading. If the pressure is low, slowly turn the
pressure adjusting screw in (Clockwise) until the correct
pressure is obtained. If the air pressure is high, turn the
adjusting screw out (counterclockwise) until the pressure is
correct. When correct pressure is reached, unplug the
heater, remove the gauge and replace the plug.
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
