Instruction

9. Supplementary Support and Stabilizer:
Install a Supplementary Support if total
chimney height is greater than 50-feet, or
if the replace manufacturer requires it. If
additional support is needed, install one or
more Supplementary Supports which can each
support 25-feet of chimney (Fig. 7). Clamp the
Supplementary Support band around the pipe
using the nut and bolt provided, and anchor
the support to nearby building framing. Always
maintain the 2-inch clearance to combustibles
from the chimney pipe. A Stabilizer is available
and may be required by some replace
manufacturers to keep the chimney vertical
and help maintain clearances to combustibles
within a chase. Clamp the Stabilizer to the pipe
using the nut and bolt provided, and secure
legs to nearby framing using plumber’s tape
or guy-wires (Fig. 8). Note: the Stabilizer does
not support the weight of the chimney, it is only
used to keep chimney centered within a chase.
10. Install Attic Insulation Shield: The Attic
Insulation Shield must be installed where the
chimney passes into an attic. Its purpose is
to prevent debris and insulation from getting
too close to the chimney. In attic areas where
this shield cannot t, or is not used you must
enclose the attic portion of the chimney in a
framed enclosure (always maintain 2-inch
air-space clearance to combustibles). If the
chimney is fully enclosed through the attic, an
Attic Insulation Shield is not required. Install
the Attic Insulation Shield as follows:
a. Remove any insulation or debris from attic
oor around the framed opening.
b. Assemble Chimney Sections until at least 18
inches of chimney extends above the Firestop.
c. Slip the Attic Insulation Shield over the
Chimney until the base sits squarely on the
framed opening (Fig. 9).
d. Secure the Attic Insulation Shield to the
top of the framed opening using at least two
