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 6 to 10):
A.Frame the fireplace using 2" x 3" or heavier lumber.
B.WARNING: Combustible materials cannot be used in the space directly above the fireplace, except for the studs above the facade that support the facing and mantel. This area must remain empty for a height of 6'8" (2032 mm) 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 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.
D.WARNING: The fireplace must not be in contact with any insulation or loose filling material. Cover the insulation with gyproc panels around the fireplace.
