Air For Combustion Air For Heating

THEORY OF

OPERATION

The Fuel System: The hose/regulator assembly attaches to the propane gas

supply. The propane gas moves through the solenoid 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 burner control sends voltage to the ignitor. The

ignitor ignites the fuel and air mixture.

The Safety Control System: This system causes the heater to shut down if the

flame goes out. The motor will continue to run, but no heat is produced.
