Operating Precautions
This is a kerosene, direct-red, forced air heater. It’s intended use is primarily
temporary heating of buildings under construction, alteration or repair.
Direct-Fired means that all of the combustion products enter the heated space.
Even though this heater operates very close to 100 percent combustion
efciency, it still produces small amounts of carbon monoxide. Carbon
monoxide (called CO) is toxic. CO can build up in a heated space and failure to
provide adequate ventilation could result in death. The symptoms of inadequate
ventilation are:
• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat
Be sure to follow advice about ventilation in the Safety Precautions section.
Forced Air means that a blower or fan pushes the air through the heater. Proper
combustion depends upon this air ow; therefore, the heater must not be
revised, modied or operated with parts removed or missing. Likewise, safety
systems must not be circumvented or modied in order to operate the heater.
When the heater is to be operated in the presence of other people the user is
responsible for properly acquainting those present with the safety precautions
and instructions, and of the hazards involved.

To prevent personal injury, unplug the heater from the wall outlet
before maintenance.
For maximum efciency and trouble-free service, make the following periodic
maintenance, cleaning and inspections.
WARNING:
Page 6
Due to varying fuel viscosities and normal component wear the pump pressure
on this heater may need to be adjusted. The heater should only be operated at
the manufacturer’s recommended burner setting.
Pressure Adjustment Screw (located at the rear of the heater)
ADJUSTMENT PROCEDURE:
1. Fill fuel tank.
2. Start heater.
3. Locate the fuel pressure.
The pressure adjustment
screw is located at the
rear of the heater, in the air
lter housing cover (slotted
adjustment screw approx. 10
o’clock position).
4. The plug directly under the adjustment screw can be used to install a pressure
gauge. It is not a second adjust screw.
5. Using a at 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 specications chart
on page 3 of the “Operating Instructions and Owners’ Manual”.
6. For best results, the nose con in the combustion chamber should be cherry red
with no dark spots and the ame should not extend beyond the nose cone.
IMPROPER PRESSURE ADJUSTMENT
Problem: Heater does not have a strong consistent ame.
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.

ADJUSTING 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 Maintenance 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 lters will cause an imbalance in the air-fuel mixture.
The best indication that this condition exists is an increase in odors or difculty
getting your heater to ignite. This heater should never be operated without the
lters in place. If required, clean lters as described under “500 Hours” and
“Annual Schedules”.
500 Hour Maintenance Schedule
1. AIR INTAKE FILTER. Remove and wash the lter element with a mild detergent,
dry thoroughly and replace. Do not oil the lter 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 ll up the passages in the nozzle, resulting in reduction of fuel
and air ow. 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 ush the fuel tank with clean fuel oil.

The parts lists and wiring diagram show the heater as it was constructed. Do not
use a heater which is different from that shown. Heater performance is effected
by air pressure setting. If there is any uncertainty about the air pressure setting,
have it checked.
A heater which is not working right must be repaired, but only by a trained,
experienced service person.
Wiring Diagram
Annual Maintenance Schedule
1. AIR OUTPUT FILTER. Remove the air output lter and tap the contaminated
side gently on a solid object to remove contaminates. Compressed air or liquids
should not be used to clean this lter. Reinstall cleaned lter in lter body in
the same position as it was when removed. If the lter appears extremely dirty,
replace it with a new lter of the same type. When replacing the lter cover, be
sure the gasket is rmly in place and the screws in the lter cover are tight to
prevent air leaks.
2. FUEL FILTER. Remove the fuel lter from fuel line and direct compressed air
through the lter in the opposite direction of fuel ow. 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 ush the fuel tank with clean fuel. The
manufacturer recommends completely lling the tank with fuel for extended
storage to minimize condensation inside the tank.
SERVICING
A hazardous condition may result if a heater is used that has been modied or is not
functioning properly.
When the heater is working normally:
* The ame is contained within the heater.
* The ame 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 shut downs of the heater.
Immediately shut down and do not use a heater that is not working normally. Do not
attempt to re-start and use the heater until it has been serviced by qualied service
personnel.
