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,

THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the
propane gas supply. The propane gas moves through the automatic
control 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 spark transformer and ignitor lights the
main burner.
The Safety Control System: This system causes the heater to shut
down if the flame goes out.
Note:
Some parts are located differently on some models.
