THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the
propane gas supply. This provides fuel to the heater.
The Ignition System: The piezo ignitor lights the burner fuel
supply.
The Automatic Control System: This system causes the heater
to shut down if the flame goes out.
UNPACKING
1. Remove all packing items applied to heater for shipment. Keep
plastic cover caps (attached to valve inlet 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.
PROPANE SUPPLY
Propane gas and propane tank(s) are to be furnished by the user.
Use this heater only with a propane vapor withdrawal supply
system. See Chapter 5 of the Standard for Storage and Handling of
Liquefied Petroleum Gas, ANSI/NFPA 58 and/or CAN/CGA B149.2.
Your local library or fire department will have this booklet.
The amount of propane gas ready for use from propane tanks varies.
Two factors decide this amount.
1. The amount of liquid propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the minimum number of 45 kg (100 lb) tanks
needed to run the heater. Connect tanks together with a manifold.

dealer will help you select the proper supply system.
