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 building codes for minimum clearance
from top of fireplace opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decorative
facing material meets fireplace surround must be com-
pletely sealed with a noncombustible material. (Figures
18 and 19)
NOTE:
No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).
with Vermont Castings Group chimney termination to find
correct size of roof hole.
There must be a 1
Z\x
” (38 mm) air space between outermost
portion of chimney sections and any adjacent combustible
surfaces. (Combustible surfaces include burnable materi-
als such as: ceiling members, joists, flooring, combustible
insulation and roof structures.)
WARNING: Do not pack required air spaces with in-
sulation or other materials.
Mark an outline of the roof hole around the center of the
point nail.
NOTE:
Hole dimensions given in the chimney
top installation instructions are
horizontal
dimensions;
therefore, the hole size must be marked on the roof ac-
cordingly.
Cover the opening of the installed chimney so debris can-
not get into the system.
Cut and frame the hole. It is good practice to use framing
lumber that is the same size as the rafters. Install the frame
securely because the chimney top and flashing anchored
to the frame must be able to withstand heavy winds.
Install Remainder of Chimney Sections
Since you have already preplanned the height of your
termination according to the
Ten Foot Rule
, continue to
install pipe to the predetermined height.
Check the chimney top installation instructions for details
on how high above the roof top the chimney sections (all
pipes) should extend.
Installing Top Housing
or Termination
Follow the installation instructions provided with the
Vermont Castings Group 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 construction
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 re-
quirements 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)
