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 Burner Control System:

This system causes the heater to shut down if

the flame goes out.
