Fuel
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.
Exhaust gases are ducted out of the heater through a vent pipe. The user must
supply the vent pipe.
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.
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.
