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 electronic ignitor sends voltage to the spark plug.
The spark plug ignites the fuel and air mixture.
The Burner Control System:
This system causes the heater to shut down if
the flame goes out.
