SAFETY INFORMATION

Continued

Never attach duct work to front or rear of heater.

Use only original replacement parts. This heater must use de- sign-specific parts. Do not substitute or use generic parts. Im- proper replacement parts could cause serious or fatal injuries.

Do not adjust regulator below 7 psig or above 20 psig.

UNPACKING

1.Remove all packing items applied to heater for shipment. Keep plastic cover caps (attached to inlet connector and hose/regu- lator 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.

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 direct spark ignitor (DSI) 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.
