PROPANE SUPPLY
Propane gas and propane tank(s) are to be fur-
nished 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 propane gas in tank(s)
2. The temperature of tank(s)
This heater is designed to operate with a minimum
20 lb (9 kg) propane tank. You may need two or
more tanks or one larger tank in colder weather.
Use a 100 lb (45 kg) 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
minimum surrounding air temperature rating for
each heater is -20° F (-29° C).
