B. RUN THE GAS LINE
CAUTION: Installation of the gas line must only be done by a qualified person in accordance with
local building codes.
IMPORTANT: DO NOT RUN THE GAS LINE IN A MANNER THAT WOULD OBSTRUCT THE
OPERATION OF THE FAN OR FAN COMPONENTS.
This fireplace is equipped with a 3/8" flexible gas line connection 18" long.
CAUTION: The manual shut off valve and millivolt board flexible gas line must not extend outside the insert
unit cavity. See the WARNING label affixed to the flexible gas line for additional installation
instructions and warnings.
1. Run the gas line into the fireplace, preferably through the left or right gas line hole provided. A gas line
knock-out is also located in the outer bottom of the insert when running the gas line through the bottom.
See Figure B-1 on page #5.
NOTE: If installing this insert into minimum opening dimensions, the gas line may need to be run after the
insert is in place due to space limitations.
If installing this gas fireplace insert into a factory-built fireplace and the factory-built fireplace has no
access holes(s) provided, an access hole of 1 ½" or less may be drilled through the lower sides or
bottom of the firebox in a proper workmanship like manner. This access hole must be plugged with
non-combustible insulation after the gas supply line has been installed.
IMPORTANT: An accessible shut off valve (included with this insert) must be installed up stream from the
regulator.
