Installation Instructions Model TLC All-Fuel Chimney - 5" to 8"
18. Fasten the wall band securely around the chimney
with the supplied nut and bolt. Check for clearances
and plumb as you fasten the wall bands to the wall.
Use a level against the chimney sections at each
support stage to keep the assembly plumb.
19. If the chimney penetrates an eave or overhang (soffit)
cut an opening with 2" clearance all around. To find
the exact spot where the chimney will pass through
the eaves, drop a plumb line from the underside of
the eaves to the outer edge of the leveled chimney.
Mark 5 or 6 points to give an outline of the hole.
Remember that the hole will need 2" clearance to the
chimney surface. Install an attic insulation shield if
space permits on the underside of the overhang. If it
is not possible, the overhang area can be enclosed
and a rafter radiation shield installed at the roof level
and a finishing plate on the underside of the soffit. If
the attic is open to the overhang, close off the access
with suitable building materials, ensuring that a 2"
airspace clearance is maintained. From above, install
the roof flashing and storm collar by following the roof
flashing section in these instructions. If the overhang
is not deep enough to allow the chimney to be fully
installed within the overhang, it will be necessary to
cut into it. DO NOT INSTALL AN OFFSET TO
CLEAR THE OVERHANG! Ensure that a 2" airspace
clearance all around the chimney is respected.
Framing and flashing the sides of the opening will be
required. Install a wall band at this level.
Note: Interior chimneys installed with a wall support
must use firestop joist shield in place of wall
bands if extending through floor/ceiling
penetrations and an attic insulation shield when
passing through an unoccupied attic space.
Adjustable Intermediate Wall Support Installation
If the total chimney height exceeds the wall support
limitations, an adjustable intermediate wall support must be
installed. Use of an adjustable intermediate wall support will
support an additional 38 feet of chimney. Slide the
assembled Intermediate wall support over the protruding
length of chimney. Fasten the Intermediate wall support to
the wall, using four ¼" by 2" wood screws through the
prepunched slots in each bracket. Install the draw band
around the protruding chimney length securely against the
support plate. Install four stainless steel sheet metal screws
firmly into the outer casing of the chimney through the
prepunched holes in the draw band. Cover the heads of the
screws with a nonhardening, waterproof caulking.
Cathedral Ceiling Support Installation
To complete a proper cathedral ceiling support installation,
the following parts are required.
• Cathedral Ceiling Support
: For sloped or angled
ceiling. Also acts as a firestop.
• Roof Flashing Assembly: Required when the chimney
penetrates a roof.
• Suit
able Lengths of Chimney
: The chimney diameter
should be sized to suit the appliance.
• Rain Cap
: Deluxe model.
The Model TLC cathedral ceiling support will support a
total of 38 feet of chimney, of which 15 feet of chimney
can be suspended below the support. All chimney joints
must be secured with locking bands.
After framing in your opening to the dimensions specified
in the Framing Details section, slide the cathedral
support box into joist opening. Once the box is at the
desired level, ensure the box is level, and nail the box to
the framing using four 2" spiral nails or #8 x 1½" wood
screws per side. The excess material sticking above the
roof can either be trimmed off before attaching the box to
the framing, or, after it is installed, the corners can be cut
and the excess material folded down onto the roof deck.
Install the support band on the chimney length at the
desired position by tightening the draw band bolt and by
screwing four stainless steel sheet metal screws through
the draw band and into the outer casing. Lower the
chimney length down through the opening in the bottom of
the support so that the support band makes contact with
the bottom of the support box (Figure 21).
Note: The male coupler of each chimney length must be up.
