CONNECTING TO GAS SUPPLY

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.

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, fireplace regu-
lator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 20, page 13. Pointing the vent
down protects it from freezing rain or sleet.

WARNING: This appliance requires a 1/2" NPT

(National Pipe Thread) inlet connection to the pres-
sure regulator.
