FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the replace unit you
are installing. If you have conicting gas types,
do not install replace. See retailer where you
purchased the replace for proper replace
according to your gas type.
INSTALLING GAS pIpING TO
FIREpLACE LOCATION
WARNING: A qualified
service person must connect
replace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect replace di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the replace and propane/LP
supply.
WARNING: For natural
gas, never connect replace to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.
Installation Items Needed
Before installing replace, 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 exible gas line with gas connec-
tor (if allowed by local codes)
* An equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the equipment shutoff
valve from your retailer.
For propane/LP connection only, the installer
must supply an external regulator. The exter-
nal regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure
to between 11" and 14" of w.c. pressure. If
you do not reduce incoming gas pressure,
replace regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 18. 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" diameter or greater to allow
proper gas volume to replace.
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 replace (see
Figure 19, page 17).
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.
