THEORY OF
OPERATION

FUELS

6
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 Burner Control System: This system causes the heater to shut down if
the flame goes out.

System
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
• 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 burner control to
shut down heater. Foreign matter may also require you to clean fuel system often.
