GAS PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply piping system by closing its individual manual
shut off valve during any pressure testing of the
gas supply piping system at test pressures equal
to or less than 1/2 psig. (3.45 kPa).
INSTALLATION INTO A SOLID FUEL
BURNING FIREPLACE OR FACTORY
BUILT FIREPLACE
The L234 Gas Inserts have been tested and ap-
proved to be vented into any masonry fireplace or
approved solid fuel burning factory built fireplace that
will allow the insert to physically fit into the firebox.
Refer to "Minimum Fireplace Dimensions" section
for minimum fireplace clearances.
If the factory built fireplace* height is too low for
your Insert, you may remove the smoke baffle
plate, damper, refractory (firebricks), glass doors,
screen rails, screen mesh and log grates from the
factory built fireplace as long as these items are
saved and are reinstalled in the event that the Insert
is removed. The fireplace flue damper can be fully
blocked open or removed for installation of the gas
fireplace insert.
Smoke shelves, shields and baffles may be removed
if attached by mechanical fasteners. If any part is
removed it must not weaken the structural integrity
of the factory built fireplace.
The fireplace and fireplace chimney must be clean
and in good working order and constructed of non-
combustible materials.
The surround panels should not seal ventilation
openings on the fireplace.
Chimney clean outs should fit properly.
NOTE: Any alterations made to the listed solid fuel
burning factory built fireplace may void the listing
of the fireplace.
Cutting any sheet metal part of the fireplace, in
which the gas fireplace insert is to be installed is
prohibited.
*Check with your local inspector before commencing
with this installation.
Installer must mechanically attach the supplied
label to the inside of the firebox of the fireplace into
which the gas fireplace insert is installed.
"WARNING: This fireplace has been converted
for use with a gas fireplace insert only and cannot
be used for burning wood or solid fuels unless all
original parts have been replaced, and the fireplace
re-approved by the authority having jurisdiction."

CAUTION:
Firebox floor removal is not covered under the
appliance safety standard (ANSI Z21.88, CSA

or bottom of the firebox in a proper workmanship
like manner. This access hole must be plugged
with non-combustible insulation after the gas
