The Fuel System: The air pump forces air through the air line. The air is then pushed through

the nozzle. This air causes fuel to be lifted 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 ignition assembly provides power to the spark ignitor.

This ignites the fuel/air mixture in the combustion chamber.

The Flame-Out Control System: This system causes the heater to shut down if the flame

goes out.
