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 di-
rectly 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 al-
ternative 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,
Figure 31 - External Regulator with Vent
Pointing Down (Propane/LP Only)
Propane/LP
Supply Tank
External
Regulator
with Vent
Pointing
Down
fireplace regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 31. 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.
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 32, page 21).
IMPORTANT: Install main gas valve (equip-
ment 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
32. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping sys-
tem 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 controls. If sedi-
ment trap/drip leg is not installedor is installed
wrong, fireplace may not run properly.
