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 de- cide this amount:

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

2.The temperature of tank(s)

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

INSTALLATION

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 installation 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).

2.Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL fitting counterclockwise into threads on tank. Tighten firmly using wrench. IMPORTANT: Position regulator so that hose leaving the regulator is in a horizontal position (see Figure 6). This places the regulator vent in the proper position to protect it from the weather.

3.Connect hose to valve inlet (see Figure 7). Tighten firmly using a wrench.

IMPORTANT: Use extra hose or pip- ing if needed. Install extra hose or pip- ing between hose/regulator assembly and propane tank. You must use the regulator supplied with heater.

4.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on pro- pane tank will stop gas flow. You may hear a click from the excess-flow check valve closing. If this happens, reset the excess-flow check valve by closing pro- pane supply valve and open again slowly.

5.Check all connections for leaks. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak that must be corrected.

6.Close propane supply valve.
