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 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.

WARNING

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 storage 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.
