PROPANE SUPPLY
Propane / L.P. gas and Propane / L.P. 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 the Propane Installation Code CAN/CGA B149.2. Your
local library or fire department will have this booklet.
The amount of Propane / L.P. gas ready for use from
Propane / L.P. tanks varies. Two factors decide this amount:
1. The amount of Propane / L.P. gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100 pound (45
kg) tanks needed to run this heater. Do not operate this
product with any tanks smaller than 100 pounds.
Less gas is vaporized at lower temperatures. You may
need two or more 100 pound (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).
