Propane Supply).
2.
Connect POL fitting on hose/regulator
assembly to propane tank(s). Turn POL
fitting counterclockwise into threads on
tank. Tighten firmly using wrench.
IMPORTANT:
Position regulator so
that hose leaving the regulator is in a
horizontal position (see Figure 6). This
places the regulator vent in the proper
position to protect it from the weather.
3.

IMPORTANT:
Use extra hose or pip-
ing if needed. Install extra hose or pip-
ing between hose/regulator assembly
and propane tank. You must use the
regulator supplied with heater.
4.
Open propane supply valve on propane
tank(s) slowly. Note: If not opened
slowly, excess-flow check valve on pro-
pane tank will stop gas flow. You may
hear a click from the excess-flow check
valve closing. If this happens, reset the
excess-flow check valve by closing pro-
pane supply valve and open again slowly.
5.
Check all connections for leaks. Apply
mixture of liquid soap and water to gas
joints. Bubbles forming show a leak
that must be corrected.

Correct all leaks at once.
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
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 de-
cide 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-pound propane tank. You may
need two or more tanks or one larger tank in
colder weather. Use a 100-pound tank for
longer operation or in very cold weather.
Less gas is vaporized at lower temperatures.
Your local propane gas dealer will help you
select the proper supply system. The mini-
mum surrounding air temperature rating for
each heater is -20
