NOTICE: Surface temperatures of adjacent walls and
mantels become hot during operation. Walls and
mantels above the firebox may become hot to the
touch. If installed properly, these temperatures meet
the requirement of the national product standard.
Follow all minimum clearances shown in this manual.
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP fireplace
directly to the propane/LP supply. This fireplace
requires an external regulator (not supplied). Install
the external regulator between the fireplace and pro-
pane/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 for propane/LP unit only (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by lo-
cal 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, pages 28 through 30.
For propane/LP units, the installer must supply an external regula-
tor. 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 pressure, heater regulator
damage could occur. Install external regulator with the vent point-
ing down as shown in Figure 17. Pointing the vent down protects it
from freezing rain or sleet.

Installing Gas Piping to Fireplace Location
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to
fireplace. If pipe is too small, undue loss of pressure
will occur.
