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 Flame-Out Control System: This system causes the heater to shut down if the flame goes out.
