FUNDAMENTALS 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.
