INSTALLATION
Continued
IMPORTANT:
For natural gas, check gas line
pressure before connecting fireplace to gas line.
Gas line pressure must be no greater than 14 inches
of water. If gas line pressure is higher, heater regu-
lator damage could occur.
CAUTION: Never connect pro-
pane/LP fireplace directly to the
propane/LP supply. This fireplace
requires an external regulator (not
supplied). Install the external regu-
lator between the fireplace and
propane/LP supply.
For propane/LP units, the installer must supply an
external regulator. The external regulator will re-
duce incoming gas pressure. You must reduce in-
coming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pres-
sure, fireplace regulator damage could occur. In-
stall external regulator with the vent pointing down
as shown in Figure 21. Pointing the vent down
protects it from freezing rain or sleet.
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 diame-
ter 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 Figures 22).
IMPORTANT:
Install equipment shutoff valve in an
accessible location. The equipment shutoff valve is
for turning on or shutting off the gas to the appliance.
Check your building codes for any special require-
ments for locating equipment shutoff valve to fire-
places.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from go-
ing into pipe. Excess sealant in pipe could result
in clogged fireplace valves.

Sediment Trap
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 22, page 18. Lo-
cate sediment trap where it is within reach for
cleaning. Install in piping system between fuel sup-
ply and heater. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace controls. If sediment trap is
not installed or is installed wrong, fireplace may
not run properly.
