THEORY OF OPERATION
The Fuel System: The air pump forces air through the air line. The air is then pushed through the nozzle. This air
causes fuel to be lifted 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 ignition control assembly provides power to the ignitor. This ignites the fuel / air mixture
in the combustion chamber.
The Flame-Out Control System: This system causes the space heater to shut down if the flame goes out.
