CAUTION: Use only new,
black iron or steel pipe. Inter
-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" or greater diameter to allow
proper gas volume to fireplace.
If pipe is too small, undue loss
of volume will occur.
Installation must include an equipment shutoff
valve, union and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up.
NPT tap must be upstream from heater (see
Figure 8, page 13).
IMPORTANT:
Install equipment shutoff valve
in an accessible location. Equipment shutoff
valve is for turning on or shutting off gas to
the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged fireplace valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
4. Attach flexible gas line to fireplace gas
regulator. See
Connecting to Gas Supply.
5. Check all gas connections for leaks. See
Checking Gas Connections,
page 14.
CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 45° male flare fitting
5/8"-18 UNF (Unified National
Fine Thread) inlet connection and
the flexible gas line provided.
WARNING: A qualified service
person must connect fireplace
to gas supply. Follow all local
codes.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
IMPORTANT:
For natural gas, check gas line
pressure before connecting fireplace to gas
line. Gas line pressure must be no greater
than 14" of water. If gas line pressure is higher,
heater regulator damage could occur.
CAUTION: Never connect
propane/LP fireplace directly
to propane/LP supply. This
fireplace requires an external
regulator (not supplied). Install
external regulator between fire
-
place and propane/LP supply.
For propane/LP units, installer must supply
an external regulator. External regulator will
reduce incoming gas pressure. You must
reduce incoming gas pressure to between
11" and 14" of water. If you do not reduce
incoming gas pressure, fireplace regulator
damage could occur. Install external regulator
with vent pointing down as shown in Figure 7.
Pointing the vent down protects it from freez
-
ing rain or sleet.
