Seal flashing to exterior of building using hightemp caulk. Attach to building using holes provided on the top of the left and right sides of outdoor flashing (see Figure 5.15).

Í Apply housewrap or building paper

For placement of combustible housewrap or building paper and non-combustible sheathing for the outside wall see Figures 5.16 and 5.17.

Special care should be taken when choosing building materials for weather proofing (i.e. building wraps, seal- ant tapes, liquid sealants, rubberized flashings, etc.). All sealant materials or building wraps installed within 6 inch- es of the top and sides of the fireplace surround must be approved to a minimum temperature of 225° F continuous exposure. Consult the material’s manufacturer to ensure product compliance.

*NOTE: All finishing materials on top of exterior sheathing must be non-combustible for a minimum of 12 inches above and on both sides of the exterior face of the appliance. This non-combustible finishing material can be up to a maximum of 6 inches thick (6 inches maximum horizontal overhang) to allow for brick and stone alcoves (see Figure 8.5).

** NOTE: Combustible house wrap or building paper	Í
MUST NOT extend over the outside of non-combustible
sheathing, and MAY extend over the flashing behind non-
combustible sheathing. Use high temp silicone or sealant
recommended by the manufacturer of the housewrap to
seal between combustible sheathing house wrap and non-
combustible sheathing. The sealant material used within
6 inches of the top and sides of the fireplace surround
must be approved to a minimum temperature of 225° F
continuous exposure.

Once the appliance is in place use enough high tempera- ture silicone sealant or manufacturer specified sealant (approved to a minimum of 225° F) to make a water tight seal between outdoor surround and exterior sheathing.

Face the perimeter of the appliance with non-combustible sheathing over shroud flanges and flashing. See Figure 5.18 for non-combustible zone.
