PROPANE SUPPLY
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. 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 pound tanks needed to run
this heater.
Do not operate this product with any tank smaller than 100 pounds.
INSTALLATION
WARNING: Review and understand the warnings
in the
Safety Information section, page 2. They are
needed to safely operate this heater. Follow all local
codes when using this heater.
WARNING: Test all gas piping and connections
for leaks after installing or servicing. Never use an
open flame to check for a leak. Apply a mixture of
liquid soap and water to all joints. Bubbles forming
show a leak. Correct all leaks at once.

2.
Connect POL fitting on hose/regulator assembly to propane
tank(s). Turn POL fitting counterclockwise into threads on
tank. Tighten firmly using wrench. Tighten regulator with

Less gas is vaporized at lower temperatures. You may need two or
more 100 pound 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
°
