clearances and dimensions as specified in
Table 1.
6. Cut Roof Opening: Determine and cut an
opening in the roof directly above the opening
below, and at least 4-inches larger than the
chimney’s outside diameter to provide at least
a 2-inch clearance all around the chimney. The
chimney must be centered within this opening
and maintain the minimum 2-inch clearance to
combustibles.
7. Install Firestop: A Firestop is required
on each floor penetration in multistory
installations. Building Codes require a Firestop
at every floor/ceiling level, including where
the chimney penetrates into the attic. Figure
3 shows a typical 2-story installation with an
attic. note: a Firestop is not installed where
the chimney penetrates through the roof. The
Firestop is installed on the underside of the
ceiling/floor framing (Fig 4). Use a minimum
of either (1) 8 penny nail or (1) 1-1/4” wood
screws per corner.
8. Assemble Chimney Sections: Lower the
female end of the first Chimney Section onto
Anchor plate (Fig. 5). 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 (Fig. 6). Do not penetrate the inner
liner of the chimney.
9. Supplementary Support and Stabilizer:
Install a Supplementary Support if total
chimney height is greater than 50-feet, or
if the fireplace 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” clearance to combustibles
from the chimney pipe. A Stabilizer is available
and may be required by some fireplace
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
