FIREPLACE INSERT IS TO BE INSTALLED, IS PROHIBITED.
1)
The refractory, glass doors, screen rails, screen mesh and log grates may be removed from the
fireplace before installing this gas fireplace insert.
2) Any smoke shelves, shields and baffles may be removed if attached by mechanical fasteners.
3) If necessary, remove the firebrick on the sides and back of the existing fireplace to obtain at least the
minimum opening requirements listed on page #2.
4) The fireplace flue damper can be fully blocked open or removed for installation of this gas fireplace
insert.
5) Trim panels or surrounds shall not seal ventilation openings in the fireplace.
6) Remove the existing chimney cap from the chimney.
7) Clean the chimney and inside of the fireplace to prevent creosote smell from entering the home.
8) Place 'THIS UNIT HAS BEEN MODIFIED' label in the bottom of the firebox so it will be visible if this
gas fireplace insert is removed.
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.
This fireplace insert 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
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 side or back, 2" from the bottom of the fireplace.
See Figure B-1 on page #5.
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.
A flexible connector should then be attached to the previously run gas line to the point where the manual
shut off valve and millivolt board flexible gas line will connect.
IMPORTANT: An accessible shut off valve (included with this fireplace insert) must be installed up stream from
the regulator.
IMPORTANT: DO NOT RUN THE GAS LINE IN A MANNER THAT WOULD OBSTRUCT THE OPERATION
OF THE FAN OR POSITION OF THE SPEED CONTROL.
