THEORY OF OPERATION
THE FUEL SYSTEM
The motor turns the fuel pump. The
fuel pump pulls fuel from the fuel
tank. The fuel pump pushes fuel
through a filter and a solenoid valve
and out the burner head nozzle. A fine
mist of fuel is sprayed into the combustion chamber.

Air for Combustion
and Heating
THE AIR SYSTEM
The motor turns the fan. The fan
pushes air into and around the combustion chamber. This air is heated and
provides a stream of clean, hot air.
THE IGNITION SYSTEM
The electronic ignitor sends voltage to
the spark plug. The spark plug ignites
the fuel and air mixture.
THE FLAMEOUT CONTROL SYSTEM
This system causes the heater to shut
down if the flame goes out. It also
allows the fan to continue running
after normal shutdown of heater. This
cools the combustion chamber.

FUELS
Use only kerosene,
or No. 1 fuel oil to
avoid risk of fire or explosion. Never
use gasoline, naphtha, paint thinners,
alcohol, or other highly flammable
fuels.
Do not use heavy fuels such as No. 2
fuel oil or No. 2 Diesel. Using heavy
fuels will result in:
• clogged fuel filter and nozzle
• carbon buildup on spark plug
• the need of nontoxic anti-icer in
fuel during very cold weather
IMPORTANT: Use a KEROSENE ONLY
container. Be sure storage container is
clean. Foreign matter such as rust, dirt,
or water will cause the flameout
control to shut down heater. Foreign
matter may also require you to clean
fuel system often.
VENTILATION
Follow the mini-
mum fresh, outside
air ventilation requirements. If proper
fresh, outside air ventilation is not
provided, carbon monoxide poisoning
can occur. Provide proper fresh, outside
air ventilation before running heater.
FRESH AIR OPENING REQUIREMENTS
Square Feet
Heater Size Opening
350,000 Btu/Hr 10.5

Operation (Continued)
8. The motor will start when extension
cord is plugged into outlet. The
heater should ignite at once. If
heater does not ignite, restart
heater. To restart heater, wait 60
seconds, then push in flameout
control reset button. Flameout
control reset button is at rear of
heater near power cord (See Figure 6).
NOTE: If starting heater for first time,
you may need to prime the pump. If
equipped, slightly open the bleeder
valve of the pump to allow air to
escape. Quickly close the valve once
fuel is seen. Wipe up excess fuel. If
equipped with canister fuel filter,
remove the canister bottom and fill
with fuel. Reassemble filter. Wipe up
any excess fuel. You may also have to
do this after taking heater out of
storage.
TO STOP HEATER
Never unplug
heater while
heater is running. Heater must go
through purge cycle. The purge cycle
cools the combustion chamber. Damage
to heater can occur if combustion
chamber is not cooled. Do not restart
heater until purge cycle is complete.
1. Turn thermostat dial to lowest
temperature setting. This will cause
heater flame to go out. The motor
will continue to run during the
purge cycle. This allows the fan to
cool the combustion chamber. When
the purge cycle is finished, the motor
will stop. Do not unplug heater until
purge cycle is finished.
2. Unplug extension cord from outlet.
3. To temporarily stop heater, set
thermostat at a temperature lower
than air around heater. Heater will
cycle back on if air temperature
around heater matches thermostat
setting.
TO RESTART HEATER
OPERATION WITH PORTABLE
GENERATOR
Before operating
heater or any
appliance from a portable generator,
verify that generator has been properly
connected to earth ground. Improper
grounding or failure to ground generator can result in electrocution if a
ground fault occurs. Refer to owner’s
manual supplied by generator manufacturer for proper grounding procedures.
The operating voltage range of the
heater is 108 to 132 Volts (120 Volts +/10%). Prior to plugging heater into
generator the output voltage should
be verified (if generator is equipped
with the automatic idle feature, the
output voltage should be measured
with the generator running at full
speed). If the voltage does not
measure in this range the heater
should not be plugged into the
generator.
Refer to Operation on page 5 for
starting, stopping, and resetting heater
procedures.
