3.4.3 Framing, Facing and Mantel
The construction of the framing, facing, and mantel must be in accordance with the
standards and the following illustrations (figures 7 to 11):
1. Frame the fireplace using 2" x 3" or heavier lumber.
2. WARNING: Combustible materials cannot be used in the space directly above the
fireplace (except for framing on the front facing). This area must remain empty for a
height of 6'8" (2032 mm) measured from the base of the appliance.
3. Frame the fireplace with vertical studs at the sides of the fireplace running from floor
to ceiling (see figure 8). If combustible facing is to be used, 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. Frame headers between the
vertical studs only as follows:
- Place 2" x 3" or 2" x 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.
4. The fireplace cannot be in contact with the house insulation material. Cover the
insulation with Gyproc panels or other rigid materials around the fireplace.
