G. Assemble Chimney Sections
Attach the fi rst chimney section or offset onto the top of the
fi replace (Figure 8.4). Sheet metal screws are required to
connect Chimney Section to Anchor Plate. Continue to add
additional sections of chimney as needed. Use a Wall Strap
every eight (8) feet of chimney height. For each additional
Chimney Section use (4) sheet metal screws provided, to
make a secure connection between the chimney sections
(Figure 8.5). Do not penetrate the inner liner of the chim-
ney.

H. Supplementary Support and Stabilizer
If additional support is needed, install one or more Sup-
plementary Supports which can each support 25-feet of
chimney (Figure 8.6). 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” clearance to combustibles from the chim-
ney pipe. A Stabilizer is available and may be required by
some fi replace manufacturers to keep the chimney verti-
cal and help maintain clearances to combustibles within a
chase. Clamp the Stabilizer to the pipe using the nut and
bolt provided, and secure lets to nearby framing using the
plumber’s tape or guy-wires ( Figure 8.7). Note: the Stabi-
lizer does not support the weight of the chimney, it is only
used to keep chimney centered within a chase.
Install supplementary
support if height exceeds
50 ft or if required by
fireplace manufacturer Each supplementary
support holds up to
25 ft. of chimney
Maintain 2 in. clearance
from chimney to framing
