back portion of the Wall Thimble to the
outside wall using (4) 8-penny nails or (4) #8,
1-1/2" wood screws in the holes provided
(Fig 24). Seal the flange of the Wall Thimble
around the wall by using a non-hardening
waterproof sealant. If your wall is more than
11-inches (275 mm) thick, you will need to
purchase a Wall Thimble Extension, allowing
installation in a wall up to 18-inches (450
mm) thick. Install the Extension by sliding
the two tubes over shields of the back
portion of the Wall Thimble. Do not install
the front portion of the Wall Thimble at this
time, but when it is installed, it will need to
extend into the room at least 2" (50 mm).
Make sure that when the Wall Thimble is fully
installed, that the Extension (if used) will
overlap both the front and back portions by
at least 1" (25 mm). If the Extension is not
used, then the front portion must overlap
the back portion by at least 1" (25 mm).
Secure the Wall Thimble Extension to the
back portion of the Wall Thimble with (2) 5/8"
sheet metal screws (Fig 24).
4. Install Tee Support: Install the Tee
Support on the outside wall. Position Tee
Support so that the Tee will be centered
inside the Wall Thimble (Figs 23, 24, & 25).
The Tee Support may be installed either
above the Tee or below the Tee, but the
Tee Support must be a maximum of one
(1) chimney section away from the Tee (Fig
25). Important: Verify that Tee Support is
level, and secure the leg brackets of the Tee
Support to the wall using (4) #8, 2-1/2" screws
for each side. Slide support base over leg
brackets to adjust for desired clearance to
wall (will adjust to allow 2" to 6" (50 mm to
150 mm) clearance to combustibles from
pipe), and secure by tightening bolts. Each
Tee Support can hold up to 25-ft of chimney.
If additional support is needed, another Tee
Support can be installed or you may install a
Tee Re-Support.
The Tee Re-Support can hold up to 25
additional feet of chimney and adjusts to
22
provide 2"-6" (50-150 mm) clearance from
combustibles. To install the Tee Re-Support,
mount the two triangular side brackets in
position using (4) #8 2-1/2" screws for each
bracket. Mount the band around the chimney
pipe. If the chimney is 7" or 8" in diameter,
add in the corresponding band section so the
band of the Tee Re-Support wraps completely
around the chimney. If the chimney is 6"
diameter, no additional band section is
needed. Slide the supporting bolts of the
Band through the slots of the Tee Re-Support
and adjust to provide the clearance
needed (Fig 23).
If additional clearance from the wall is
necessary, an Extended Wall Bracket can
be used. An Extended Wall Bracket acts as
a support to the chimney and can hold up
to 25-ft of chimney. Additional Extended
Wall Brackets can be used for additional
support if necessary. Mount the lower, long
side brackets to the wall using (4) #8, 2-1/2"
screws for each side. Mount the top, short
brackets to the wall also using (4) #8, 2-1/2"
screws for each side. Attach the supporting
arms of the Extended Wall Bracket using the
hardware provided. The unflanged end of
the arms faces downward (see Fig 26). Slide
the supporting bolts of the Band through the
slots of the Extended Wall Bracket and adjust
to provide the clearance needed.
5. Install Tee and Cleanout Chimney
Section: The Tee can be mounted directly
to the Tee Support or it be twist locked onto
a desired length of Chimney to be used as
the cleanout section. Use only one chimney
section (any length) to attach to bottom of
the Tee. Tighten support band around the
Tee or Chimney section, as appropriate, at the
proper height to insure that Tee is centered
through Wall Thimble (Fig 24). Use the 1/2"
(13 mm) sheet metal screws provided to
insure a tight connection between support
band and chimney section. Connect support
band to support base using the 1/2" (13 mm)
sheet metal screws provided (Fig 25). Twist
