INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified
service person must connect
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.
WARNING: For natural
gas, never connect heater to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.

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 connec-
tor (if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alter-
native 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 ex-
ternal 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. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" inside diameter or greater to
allow proper gas volume to fire-
place. If pipe is too small, undue
loss of volume will occur.
