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