THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the propane gas supply. The propane gas moves through the automatic control valve and out the nozzle.
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 spark transformer and ignitor lights the main burner.
The Safety Control System: This system causes the heater to shut down if the flame goes out.
Note: Some parts are located differently on some models.
