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.
