Theory of Operation
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 ignition control assembly provides
power to the ignitor. This ignites the
fuel/air mixture in the combustion
chamber.
THE FLAME-OUT CONTROL SYSTEM
This system causes the heater to shut
down if the flame goes out.
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 build-up on spark plug
• the need of non-toxic 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.
• Heaters used in the vicinity of
tarpaulins, canvas, or similar
enclosure materials shall be located
a safe distance from such materials.
The recommended minimum safe
distance is 10 feet. It is further
recommended that these enclosure
materials be of a fire retardant
nature. These enclosure materials
shall be securely fastened to
prevent them from igniting or from
upsetting the heater due to wind
action.
• 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.
• This heater is equipped with a
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.
