CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection
to the pressure regulator.
WARNING: A qualified ser-
vice person must connect heater
to gas supply. Follow all local
codes.
CAUTION: Never connect pro-
pane/LP fireplace directly to the
propane/LP supply. This fireplace
requires an external regulator
(not supplied). Install the external
regulator between the fireplace
and propane/LP supply.
WARNING: Never connect
natural gas fireplace 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 *
• ground joint union
• sediment trap
• tee joint
• pipe wrench
• test gauge connection *
* 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 35.
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 19. Pointing the vent down
protects it from freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. In-
ternally-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
heater. If pipe is too small, undue
loss of volume will occur.
