Gas Control
Flexible Gas
Hose (if allowed
by local codes)
WARNING: This appliance requires a 3/8" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: A qualifi ed ser vice per son must con nect
appliance to gas sup ply. Follow all local codes.
CAUTION: Never connect propane/LP fi replace
directly to the propane/LP supply. This unit re quires
an external regulator (not supplied). Install the external
regu la tor be tween the unit and propane/LP supply.
WARNING: Never connect natural gas fi replace to
pri vate (non-utility) gas wells. This gas is com mon ly
known as wellhead gas.
Installation Items Needed
Before installing appliance, 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 fl exible gas line with gas con nec tor (if allowed by lo cal
codes) (provided)
* A CSA design-certifi ed equipment shutoff valve with 1/8" NPT
tap is an ac cept able alternative to test gauge con nec tion. Pur chase
the optional CSA design-certifi ed equipment shutoff valve from
your dealer. See Accessories, page 22.
For propane/LP units, the installer must supply an external reg u -
la tor. The external reg u la tor will reduce incoming gas pressure. You
must reduce in com ing gas pressure to between 11 and 14 inches of
water. If you do not reduce in com ing gas pressure, regulator dam-
age could occur. Install external reg u la tor with the vent point ing
down as shown in Figure 8 page 9. Pointing the vent down protects
it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe.
In ter nal ly-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
di am e ter or greater to allow prop er gas vol ume to
appliance. If pipe is too small, undue loss of volume
will occur.
