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
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. It is recommended you use a
100 lb (45 kg) tank for longer operation. See
chart below. 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 0° F (-18° C).
