THEORY OF	The Fuel System: An air pump is located on one end of the motor shaft. The
	air pump forces air through the air line. The air is then pushed through the burner
OPERATION
	head nozzle. The moving air causes fuel to be lifted from the tank. The fuel and air
	mixture is sprayed into the combustion chamber in a fine mist.
	The Air System: The motor turns a fan which 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 causes the spark plug to ignite the
	fuel and air mixture.
	The Flame-Out Control System: This system causes the heater to shut down
	if the flame goes out.
