FIREPLACE INSTALLATION

INSTALLING GAS PIPING TO FIREPLACE
LOCATION
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by lo-
cal codes)
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap
is an acceptable alternative to test gauge connection. Purchase the
CSA design-certified equipment shutoff valve from your retailer.
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 inches 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.
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
CAUTION: For propane/LP units, never connect
fireplace directly to the propane/LP supply. This
heater requires an external regulator (not supplied).
Install the external regulator between the fireplace
and propane/LP supply.

FIREPLACE INSTALLATION
Installing Gas Piping to Fireplace Location
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 threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged fireplace valves.
CAUTION: 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.

* The CSA design-certified equipment shutoff valve may be sup-

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" diam-
eter or greater to allow proper gas volume to fireplace.
If pipe is too small, undue loss of pressure will occur.
