Figure 5 - Framing the Fireplace
WARNING!
Do not apply combustible finishing materials over any part of the black face of this fireplace or a structure fire
may result. The black metal fireplace front may only be covered with noncombustible materials such as ce-
ramic tile, brick, or stone. Do not cover or block any cooling air slots. Do not cover any portion of the opening
to the fireplace that would prevent the installation of an authorized glass door.

The MHR36 and MHC36 fireplaces will fit a framed opening of 39-5/8 in. wide x 33-5/8 in. tall. The finished cavity
depth must be no less than 19-3/4 in.

All required clearances to combustibles around the fireplace must be adhered to.
Chimney sections at any level
require a 2
in.
minimum air space clearance between the framing and chimney section.

A minimum 1 in. air clearance must be
maintained at the back and sides of the
fireplace assembly except at the nail-
ing flange where the clearance is 1/2 in.
Chimney sections at any level require a
2 in. minimum air space clearance be-
tween the framing and chimney section.

The top header may be positioned on the hemmed
seam across the top of the fireplace assembly.
