* NOTE: All fi nishing 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 fi nishing 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
MUST NOT extend over the outside of non-combustible
sheathing, and MAY extend over the fl ashing behind
non-combustible sheathing. Use high temp caulk to seal
between combustible sheathing house wrap and non-
combustible sheathing.
Once the appliance is in place use enough silicone caulk
to make a water tight seal between outdoor surround and
exterior sheathing.
Face the perimeter of the appliance with non-combustible
sheathing over shroud fl anges and fl ashing. See Figure
5.17 for non-combustible zone.
