You must provide propane gas and
propane 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 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 tempera-
tures. 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.
