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.
