THEORY OF OPERATION

PROPANE SUPPLY

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.
This heater will operate with a 20-pound (9,07 kg) propane tank.
However, you can only operate it in the LOW position during mildly
cool weather. At higher heat settings or during colder weather, you
must use larger tanks.
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 (45 kg)
tanks needed to run the heater. Connect tanks together with a
manifold.
Average Temperature ( F[ C]) Number
At Tank Location
60 (15,6 )
40 (4,4 )
32 (0 )
20 (-6.7 )
10 (-12,2 )
0 (-17,8)
Less gas is vaporized at lower temperatures. Your local propane gas
dealer will help you select the proper supply system.
