Installing Top Housing

Follow the installation instructions provided with the
MHSC chimney termination you have selected.
Installing Chimney in a Chase
Refer to Page 4, Figure 2 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and construc-
tion of chase may vary with type of building. These
instructions are not a substitute for local building codes.
You must check your local building codes to determine
specific requirements for your city or state. NOTE:
Other building materials may be required in addition to
firestop spacers.
Finishing
CAUTION: All joints between the finished wall and the
fireplace surround (top/sides) must be sealed with non-
combustible material to prevent cold air leakage into
the room. Only noncombustible material may be applied
to the facing of the fireplace surround. (Black painted
area) (Fig. 18)
Finish Wall
Finish the wall with material of your choice. Do not
install a combustible mantel shelf less than 12”
(305 mm) above the grille opening. Do not install a
mantel face plate less than 6” (159 mm) from top
of grille opening. (Fig. 20) If a combustible material is
used below a flat mantel shelf, consult your local build-
ing codes for minimum clearance from top of fireplace
opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or deco-
rative facing material meets fireplace surround must
be completely sealed with a noncombustible material.
(Figures 19 and 20)
NOTE: No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).
