3.4.3 Framing, Facing, Mantel, and Combustible Shelf
The construction of the framing, facing, and mantel must be in accordance with the standards
and the following illustrations (figures 4 to 11):
A. Frame the fireplace using 2" × 3" or heavier lumber.
B.
WARNING:
Combustible framing material cannot be used in the space directly above the
fireplace, except for the studs above the facing that support the facing material and
mantel. This area must remain empty for
a height of 7
′
(2,15 m)
measured from the base
of the appliance.
C. Frame the fireplace with vertical studs at the sides of the fireplace running from floor to
ceiling (see figure 6). Position the studs back from the front edge of the fireplace, a space
the thickness of the facing material so that the facing can be installed flush with the
fireplace facing (within limitations of figure 11). Frame headers between the vertical studs
only as follows:
−
Place 2" × 3" or 2" × 4" headers, only along the upper part of the front, side and back
faces. Do not put wood or any combustible material within the area above the fireplace
except on the front facing.
−
Place headers only as required to support the facing and mantel.

WARNING: The fireplace must not be in contact with any insulation or loose filling
material. Cover the insulation with gyproc panels around the fireplace.
