For propane/LP connection only, the installer must supply an
external regulator. The 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 the vent pointing down as shown in Figure 30. Pointing the
vent down protects it from freezing rain or sleet.
CAUtION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diameter
or greater 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 fireplace (see Figure 31).
IMPORTANT:
Install main gas valve (equipment shutoff valve)
in an accessible location. The main gas valve is for turning on or
shutting off the 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.
We recommend that you install a sediment trap/drip leg in supply
line as shown in Figure 31. Locate sediment trap/drip leg where it
is within reach for cleaning. Install in piping system between fuel
supply and fireplace. Locate sediment trap/drip leg where trapped
matter is not likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into fireplace gas con
-
trols. If sediment trap/drip leg is not installed or is installed wrong,
fireplace may not run properly.

CONNECtING FIREPLACE tO GAS SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not provided)
1. Open lower louver door panel by gently pulling forward.
2. Route flexible gas line (provided by installer) from equipment
shutoff valve to fireplace. Route flexible gas supply line through
one of the access holes on side of fireplace.
3. Attach flexible gas line from gas supply to control valve (see
Figure 32).
4. Check all gas connections for leaks. See
