3. Connect hose to inlet connector.

Tighten firmly using a wrench.

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 the Propane Installation Code CAN/ CGA B149.2. Your local library or fire de- partment will have this booklet.

The amount of propane gas ready for use from propane tanks varies. Two factors de- cide this amount:

1.The amount of propane gas in tank(s)

2.The temperature of tank(s)

The chart below shows the number of 100 pound tanks needed to run this heater.

Less gas is vaporized at lower temperatures. You may need two or more 100 pound tanks or one larger tank in colder weather. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding air temperature rating for each heater is -20°F (-29°C).

WARNING: Review and un- derstand the warnings in the Safety Information section, page

2.They are needed to safely op- erate this heater. Follow all local codes when using this heater.

WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

1.Provide propane supply system (see Propane Supply above).

2.Connect fuel gas connector fitting on hose/regulator assembly to propane tank(s). Turn counterclockwise into threads on tank valve. Tighten firmly using wrench. IMPORTANT: Tighten regulator with vent pointing down. Pointing vent down protects regulator from weather damage.
