Framing construction

The frame, on the sides and back of the fireplace, must be made of 2"x 3" (5 cm x 8 cm) or
larger. 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.
Do not use combustible materials for the frame directly above the fireplace, except for
studs above the siding that support the finishing material and mantel. This area should
remain empty to a height of 80" (2.03 m) measured from the base of the fireplace.
Build the fireplace frame using vertical studs placed on the sides of the fireplace, from the
floor to the ceiling. The studs must be set back from the front edge of the fireplace by a space
equivalent to the thickness of the finishing material, so that it is flush with the finish of the
fireplace. Headers between studs should be installed as follows:
− The headers must be 2" x 3" (5 cm x 8 cm) or a maximum dimension equivalent to the depth of
the top standoff. Do not put wood or other material in the area above the fireplace, except for the
cripple studs needed to install the finishing material.
− Install only the cripple studs needed to support the finishing material and mantle.
Do not fill the required empty space inside the enclosure with insulation or any other
material.
The fireplace must not be in contact with any insulation or loose filling material. Inside the chase,
around the fireplace, insulation should be covered with drywall panels or any other finishing
material except where non-combustible material is required.
