General Safety Information

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 produces carbon monoxide,
which is listed by the State of
California as a reproductive toxin
under Proposition 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.
