Air Out
The Fuel System:
The air pump forces air
through the air line. The air is then pushed
through the nozzle. This air causes fuel to
lift from the tank. A fine mist of fuel is
sprayed into the combustion chamber.
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.

WARNING: Review and un-
derstand the warnings in the
Safety Information section, page
2. They are needed to safely op-
erate this heater. Follow all local
codes when using this heater.
TO START HEATER
1.
Follow all ventilation and safety in-
formation.
2.
Fill fuel tank with kerosene or No. 1
fuel oil.
3.
Attach fuel cap.
4.
Turn thermostat knob clockwise to the
HIGH position.
5.
Plug power cord of heater into three-
prong, grounded extension cord. Exten-
sion cord must be at least six feet long.
Extension Cord Wire Size
Requirements
• 6 to 10 feet long, use 18 AWG rated
cord
• 11 to 100 feet long, use 16 AWG
rated cord
• 101 to 200 feet long, use 14 AWG
rated cord
6.
Plug extension cord into standard 120
volt/60 hertz, three-hole, grounded out-
let.
Note
:
Ignitor will preheat for five
seconds then heater will start.
7.
Adjust thermostat knob to the de-
sired setting.
Note:
A cold heater may affect the thermo-
stat setting. This thermostat is a general-
heating control. It is not intended for precise
temperature control. Adjust thermostat un-
til heater cycles at the desired setting.
Do not use heavy fuels such as No. 2 fuel oil
or No. 2 Diesel. Using heavy fuels will
result in a clogged fuel filter and/or nozzle.
IMPORTANT:
Use a KEROSENE ONLY
storage container. Be sure storage con-
tainer is clean. Foreign matter such as
rust, dirt, or water will cause the ignition
control assembly to shut down the heater.
Foreign matter may also require you to
clean fuel system often.
Provide at least a three-square-foot opening
of fresh, outside air for each 100,000 Btu/Hr
rating. Provide extra fresh air if more heat-
ers are being used.
Example:
A 165,000 Btu/Hr heater requires
one of the following:
• a two-car garage door (16 feet wide open-
ing) raised 4 inches
• a single-car garage door (9 feet wide
opening) raised 7 inches
• two 30 inch wide windows raised
twelve inches
WARNING: 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.
FUELS
VENTILATION
WARNING: Follow the mini-
mum fresh, outside air ventila-
tion requirements. If proper fresh,
outside air ventilation is not pro-
vided, carbon monoxide poison-
ing can occur. Provide proper
fresh, outside air ventilation be-
fore running heater.
The Ignition System:
The ignition control
assembly provides power to the ignitor.
This ignites the fuel/air mixture in the com-
bustion chamber.
The Flame-Out Control System:
This sys-
tem causes the heater to shut down if the
flame goes out.
