6.3.7.1 Framing
The construction of the framing, facing, and mantel must be in accordance with the standards and the
following instructions:
Frame the sides and back of the fireplace using 2" × 3" (5 cm x 8 cm) or heavier lumber. However, the front
studs as well as headers on top of the fireplace must be of a depth no more than the depth of the top
standoffs.
Frame the fireplace with vertical studs at the sides of the fireplace running from floor to ceiling. 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

Place the front facing headers in 2" × 3" or of a depth no more than the depth of the top standoffs.
Do not put wood or any material within the area above the fireplace.
