General Safety Information
(Continued)
Theory of Operation 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 flame-out control to
shut down heater. Foreign matter may also
require you to clean fuel system often.
The Fuel System: The air pump forces air
through the air line. The air is then pushed
through the burner head 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.
The Ignition System: The electronic
ignitor sends voltage to the spark plug.
The spark plug ignites the fuel and air
mixture.
The Flame-out Control System: This
system causes the heater to shut down if
the flame goes out.

• Use only in well-vented areas.
Provide at least three square feet of
fresh, outside air for each 100,000
Btu/Hr of rating. This heater pro-
duces carbon monoxide, which is
listed by the State of California as a
reproductive toxin under Proposi-
tion 65.
• Use only in places free of flammable
vapors or high dust content.
• Use only with the electrical voltage
and frequency specified on model
plate.
• Use only a three-prong, grounded
extension cord.
• Minimum heater clearances from
combustibles:
Outlet: 8 Ft. Sides: 4 Ft.
Top: 4 Ft. Rear: 4 Ft.
• Locate heater on a stable and level
surface while hot or running or a fire
may occur.
• When moving or storing heater, keep
heater in a level position or fuel
spillage may occur.
• Keep children and animals away
from heater.
• Unplug heater when not in use.
• When used with thermostat, heater
may start anytime.
• Never use heater in living or sleep-
ing areas.
• Never block air inlet (rear) or air
outlet (front) of heater.
• Never move, handle, refuel, or
service a hot, operating, or plugged-
in heater.
• Never attach duct work to front or
rear of heater.
