PROPANE/LP SUPPLY VENTILATION INSTALLATION

PROPANE/LP SUPPLY

Propane/LP gas and propane/LP tank(s) are to be furnished by the user.

Use this heater only with a propane/LP vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and the Propane Instal- lation Code CAN/CGA B149.2. Your local library or fire depart- ment will have these booklets.

The amount of propane/LP gas ready for use from propane/LP tanks varies. Two factors decide this amount:

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

2.The temperature of tank(s)

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

Do not operate this product with any tank smaller than 100 pounds.

Less gas is vaporized at lower temperatures. You may need a larger tank in colder weather. Your local propane/LP gas dealer will help you select the proper supply system. The minimum surrounding air temperature rating for each heater is -20°F.

VENTILATION

WARNING: Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ven- tilation before running heater.

Provide at least three square feet of fresh, outside air for each 100,000 Btu/Hr of rating. This heater requires a fresh air opening of at least 11.25 square feet. Provide extra fresh air if more heaters are being used.

INSTALLATION

WARNING: Review and understand the warnings in the Safety Information section, page 2. They are needed to safely operate this heater. Follow all local codes when using this heater.

WARNING: Test all gas piping 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/LP supply system (see Propane/LP Supply).

2.Connect POL fitting on hose/regulator assembly to propane/LP tank(s). Turn POL fitting counterclockwise into threads on tank. Tighten firmly using a wrench. IMPORTANT: Tighten regula- tor with black adjustment knob pointing down. Pointing adjust- ment knob down protects regulator from weather damage.

3.Connect hose to inlet connector. Tighten firmly using a wrench. IMPORTANT: Extra hose or piping may be used if needed. Install extra hose or piping between hose/regulator assembly and propane/LP tank. You must use the regulator supplied with the heater.

4.Open propane/LP supply valve on propane/LP tank(s) slowly. Note: If not opened slowly, excess-flow check valve on pro- pane/LP tank will stop gas flow. If this happens, you may hear a click inside the regulator assembly. To reset the excess flow check valve, close propane/LP supply valve and open again slowly.
