PRODUCT
IDENTIFICATION
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 the
Propane
Installation Code 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 number of 100 lb. (45
kg) pound tanks needed to run this heater.
Average Temperature
Number Of Tanks
At Tank
(100 lb/45 kg)
Above 20° F (-6.7° C)
2
20° F (-6.7° C) to 0° F (-18° C)
3
Below 0° F (-18° C)
Use larger tank
Less gas is vaporized at lower temperatures. You
may need two or more 100 lb. (45 kg) tanks or one
larger tank in colder weather. 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).
Smaller tanks can be used for limited run times
but it is recommended to use larger tanks for
optimum performance.
