CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 45° male flare fitting
5/8"-18 UNF (Unified National
Fine Thread) inlet connec-
tion and the flexible gas line
provided.
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
IMPORTANT: For natural gas, check gas line
pressure before connecting fireplace to gas line.
Gas line pressure must be no greater than 14" of
water. If gas line pressure is higher, heater regula-
tor damage could occur.
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.
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" of
water. If you do not reduce incoming gas pressure,
fireplace regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 21, page 18. Pointing the vent
down protects it from freezing rain or sleet.
