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 ignition con-
trol assembly provides power to the ignitor.
This ignites the fuel/air mixture in the com-
bustion chamber.
The Flame-Out Control System: This sys-
tem causes the heater to shut down if the
flame goes out.
