1. Remove all packing items applied to heater for shipment. Keep plastic cover caps

The Fuel System: The hose/regulator assembly attaches to the propane gas supply. The
propane gas moves through the thermoelectric valve and out the nozzle.
The Air System: The motor turns the fan. The fan pushes air into and around the com-
bustion chamber. This air is heated and provides a stream of clean, hot air.
The Ignition System: The piezo spark ignitor (Model 5070A) or Electronic Module
(Model 5075A) sends voltage to the electrode. The spark at the electrode ignites the fuel
air mixture.
The Safety Control System: This system causes the heater to shut down if the heater
overheats for any reason including loss of electric power. (The fan will continue to operate
if electric power is not lost.)
