fuels.
Never use heater where gasoline, paint thinner, or other highly ammable vapors are present.
Follow all local ordinances and codes when using heater.
Use only in well-vented areas. Provide at least a 2800 square cm opening of
fresh, outside air for each 100,000 BTU/Hr of rating.
Use only in places free of ammable vapors or high dust content.
Use only with the electrical voltage and frequency specied on model plate.
Use only a three-wire, grounded (earthed) extension cord.
Minimum heater clearances from combustibles:
Outlet: 250 cm Sides, Top, and Rear: 125 cm
Locate heater on a stable and level surface while hot or running or a re may occur.

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 ne 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 ame goes out.

WARNING
Use only kerosene or No. 1 fuel oil to avoid risk of re or explosion. Never use gasoline, naphtha, paint thinners, alcohol or other highly ammable fuels.
Do not use heavy fuels such as No. 2 fuel oil or No. 2 Diesel. Using heavy fuels will result in:
clogged fuel lter and nozzle
carbon build up on spark plug
use 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.

VENTILATION
!
WARNING
Follow the minimum 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.
Provide a fresh air opening of at least 2800 square cm for each 100,000 BTU/Hr rating. Provide extra fresh air if more heaters are being used.
OPERATION
Example:
a two-car garage door raised 15.24 cm
a single-car garage door raised 22.86 cm
two, 76.20 cm windows raised 30.48 cm
