THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the propane gas supply. This provides fuel

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 piezo ignitor lights the burner.
The Automatic Control System: This system causes the heater to shut down if the flame goes out.
