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.
For propane/LP units, 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 regula-
tor with the vent pointing down as shown in
Figure 21. Pointing the vent down protects it
from freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" or greater diameter to allow
proper gas volume to fireplace.
If pipe is too small, undue loss
of volume will occur.

Extension Cord
Use extension cord if needed. The cord must
have a three-prong, grounding plug and a
three-hole receptacle. Make sure cord is in good
shape. It must be heavy enough to carry the
current needed. An undersized cord will cause
a drop in line voltage. This will result in loss of
power and overheating. Use a No. 16 AWG cord
for lengths less than 50 feet.
CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 45° male flare fitting
5/8"-18 UNF (Unified National Fine
Thread) inlet connection and the
flexible gas line provided.
WARNING: A qualified
service person must connect
fireplace to gas supply. Follow
all local codes.
