UNPACKING
THEORY OF OPERATION
1.Remove all packing items applied to heater for shipment. Keep plastic cover caps (attached to inlet connector and hose/regulator assembly) for storage.
2.Remove all items from carton.
3.Check all items for shipping damage. If heater is damaged, promptly inform dealer where you bought heater.
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 direct spark ignitor (DSI) sends voltage to the spark plug/ignitor. The spark plug/ignitor ignites the fuel and air mixture.
The Safety Control System: This system causes the heater to shut down if the flame goes out.
