INSTALLATION
Continued
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified
service person must connect
fireplace Insert to gas supply.
Follow all local codes.
CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and propane/LP supply.
WARNING: Never connect
natural gas fireplace insert to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.
Installation Items Needed
Before installing fireplace insert, 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) (not provided)
* A CSA design-certified equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certified equipment shutoff valve from your
dealer. See
Accessories, page 34.
For propane/LP units, 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 pres
-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 13, page 13. Pointing the vent
down protects it from freezing rain or sleet.
