WARNING
This fireplace has been converted for use with
gas only and cannot be used for burning wood
or solid fuels unless all original parts have been
replaced and the fireplace has been re-approved
by the authority having jurisdiction.
Cutting any sheet metal parts of the
fireplace, in which the gas fireplace insert
is to be installed, is prohibited.
If the factory-built fireplace has no gas
access hole(s) provided, an access hole
of 1
¹⁄₂
" (37.5mm) 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

installations into solid fuel Masonry or Factory Built
Noncombustible fireplaces that have been installed
in accordance with the National, Provincial, State
and local building codes.
2. Measure for minimum fireplace opening requirement
on Page 4 of this installation manual. (If firebrick
[refractory] is removed from a factory built
fireplace in order to gain minimum gas fireplace
insert opening requirements, a minimum of 1/4"
(6.4mm) air space is required between the gas
insert fireplace's outer casing and the inner wall
of the factory built fireplace).
3. To assure top performance, safety and efficiency, all
inserts must be installed with an approved 4"
diameter flue liner, with exception of RHE25, which
should be installed with an approved 3" liner,as per
CSA-B.149 or National Fuel Code ANSI Z223.
WARNING
Some factory built fireplaces have air passages
on face of fireplace for zero clearance capabili-
ties. All trim kits are designed so as to allow
airflow to these passages. Under no circum-
stances should these passages be blocked.
