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.
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 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.
