PROPANE SUPPLY
You must provide propane gas and tank(s).
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 100-pound tanks
needed to run the heater. Connect tanks together with a manifold. Do
not operate this product with any tank smaller than 100 pounds.

Less gas is vaporized at lower temperatures. Two or more 100-pound
tanks or one larger tank may be needed in colder weather. Your local
propane gas dealer will help you select the proper supply system.

• Turn off propane supply to heater when not in use.

sign-specific parts. Do not substitute or use generic parts. Im-
proper replacement parts could cause serious or fatal injuries.
