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 (Optional Extra): This system causes the
heater to shut down if the flame goes out.

FUELS
Do not use heavy fuels such as 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 or PARAFFIN 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 (optional extra). Foreign matter may also require
you to clean fuel system often.
! WARNING
Use only kerosene or paraffin to avoid risk of fire or explo-
sion. Never use petrol, naphtha, paint thinners, alcohol or
other highly flammable fuels.
