WARNING: Review and under-
stand 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.
1. Provide propane supply system (see
Propane Supply above).
2. Connect fuel gas connector fitting on
hose/regulator assembly to propane
tank(s). Turn counterclockwise into
threads on tank valve. Tighten firmly
using wrench.
IMPORTANT: Tighten
regulator with vent pointing down.
Pointing vent down protects regulator
from weather damage.
3. Connect hose to inlet connector.
Tighten firmly using a wrench.
IMPORTANT: Extra hose or piping
may be used if needed. Install extra
hose or piping between hose/regulator
assembly and propane tank. You must
use the regulator supplied with 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.
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 the Propane Installation Code CAN/
CGA B149.2. Your local library or fire de-
partment 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)
The chart below shows the number of 100
lb. (45 kg) pound tanks needed to run this
heater.
