INSTALLING GAS PIPING TO FIREPLACE
LOCATION
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.
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 local
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 ex-
ternal 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.
