Glass Doors
If glass doors are to be installed on these
fi replaces, refer to specifi c installation instruc-
tions packed with the glass doors. Use only
the doors that are listed for use with these
fi replaces. Use of other non-listed glass door
on these fi replaces may constitute a potential
fi re hazard and is not recommended.
If you’re installing a gas line, connect it before
the fi replace is framed and enclosed in the
fi nished wall. The gas knockout is determined
by the indentation located at the bottom and
slightly off center in the side refractories. THE
KNOCKOUT IS ALWAYS REMOVED FROM
INSIDE THE FIREPLACE. DO NOT REMOVE
THE KNOCKOUT UNLESS YOU ARE INSTALL-
ING A GAS LINE. If removal is attempted from
the outer wrapper, side refractory damage
may occur. With a medium-sized hammer,
lightly tap the surface of the indentation. The
refractory material is very thin in this area
and is easily removed. Once a small hole has
been made, continue tapping until you have
reached suffi cient diameter for the gas line to
fi t through. The entire knockout does not have
to be removed. Remove insulation in the gas
line channel.
IMPORTANT: REPACK INSULATION MATE-
RIAL IN SQUARE HOLE AROUND GAS LINE,
INTERIOR AND EXTERIOR OF FIREPLACE,
TO SEAL.

fi replace opening.
These fi replaces have been marked with a
maximum rating of 26,000 BTU to assure
that homeowners do not exceed the allowable
limits for all allowed installations of mantels.
That limit may be increased to 40,000 BTU,
provided that the mantel installed complies
with the 18-inch limitation and a copy of these
instructions are available.
