THEORY OF OPERATION
The Fuel System: The hose / regulator assembly attaches to the Propane / L.P. gas supply. The Propane / L.P.
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.
