For55/85/15 models, the propane gas moves through the automatic control valve, burn rateadjustment valve and out the injector. For 170 models, the propane gas moves through thesolenoid 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 combustionchamber. This air is heated and provides a stream of clean, hot air.The ignition System: For 55/85/15 models the high voltage ignitor sends voltage to the sparkignitor. For 170 models direct spark ignitor sends voltage to the spark ignitor.
