Theory of Operation

The Fuel System: The hose/regulator assembly attaches to the propane gas supply. For 55/85/125 models, the propane gas moves through the automatic control valve, burn rate adjustment valve and out the injector. For 170 models, the propane gas moves through the solenoid valve, burn rate adjustment valve and out the injector.

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: For 55/85/125 models the high voltage ignitor sends voltage to the spark ignitor. For 170 models direct spark ignitor sends voltage to the spark ignitor. The spark ignitor ignites the fuel and air mixture.

The Safety Control System: This system causes the heater to shut down if the fame goes out. The motor will continue to run, but no heat is produced.
