THEORY OF OPERATION
The Fuel System: The motor turns the fuel pump. The fuel pump pulls fuel from the fuel tank. The fuel pump
pushes fuel through a filter and a solenoid valve and out the burner head nozzle. 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 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. It also allows
the fan to continue running after normal shutdown of heater. This cools the combustion chamber.
