THEORY OF OPERATION
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.
