NOTE: THE CHIMNEY MUST EXTEND AT LEAST 3” (75 MM) INTO
THE LIVING SPACE WHERE THE STOVE PIPE
CONNECTOR WILL BE ATTACHED
TO THE CHIMNEY BRANCH.
From outside the building, slide the assembly (Chimney Length installed
on the Tee branch) through the Wall Thimble ensuring the male coupling
on the Tee is facing upward. Insert and twist lock the Adaptor Ring in
the female coupler of the Insulated Tee (bottom of Tee). Place the
assembled Wall Support against the wall (support plate facing up) directly
below the Tee. Slide the Wall Support up to the Tee ensuring that the stub
of the Adaptor Ring (Figure 17) is inserted into the opening of the
Support Plate.
Lock securely into the Tee branch by twisting clockwise. A Locking
Band must then be installed to secure the connection. Make sure the
nut and bolt are facing down to prevent any water from collecting in the
Locking Band. The Tee branch extension must protrude a minimum of
3" into the room.
NOTE: Ensure that you have set aside the Tee Plug, if not, do so
now as you will require it later.
Prior to securing ensure that the Insulated Tee assembly is plumb, level
and sitting flush on the Support Plate. Secure to the wall through the
pre-punched holes located on each side of the Wall Support Brackets
using eight (8) #14 x 1/2" hex head lag screws or #10 x 2" wood screws.
Make sure they go into solid bracing. If the support is properly
positioned, these lag bolts will go into wall studs placed on 16” centers.
For concrete block or poured foundation use suitable fasteners.
Install an appropriate Insulated Chimney Length such as a one foot (or
longer if required-not to exceed 24 inch) Length of Insulated Chimney
to the horizontal branch of the Insulated Tee.

The Adjustable Wall support (AWS) will support up to 38 feet (11.5m)
of chimney, all of which must be above the support with the exception
of the 1 foot cleanout section and/or the Insulated Tee Plug, which is
installed below the support (Figure 15).
Install the interior inner half (with round plate and tabs) of the wall thimble
into the inside wall opening, ensuring that the shield slides over the
shield of the exterior outer half (see Figure 16). Once in place and flush
against the wall, install the black finishing trim plate (round black plate)
onto the finished inside wall surface and fasten in place with appropriate
fasteners through the four pre-punched holes.
NOTE: When the combustible wall thickness exceeds the telescoping
range of the Wall Thimble, it is permissible to field fabricate a metal sleeve
extension. The sleeve extension must be of a galvanized sheet metal of
minimum 26 gauge. It must also overlap a minimum of one inch (1") over
each of the thimble sleeves and be secured with a minimum of 3 rivets
or screws.

Assemble the Wall Support (Figure 17) by attaching the 2 side brackets
to the support plate with the supplied hardware. Ensure that the female
coupler attached to the underside of the support plate is facing down.
For an adjustment of the support plate, align the fixed holes on the
support plate with the elongated holes on the side brackets.
For a non combustible wall, cut a hole 3/16" greater than the outside
diameter of the chimney.
NOTE:
To reduce cold air infiltration into the dwelling you
can install the optional Universal Shielding Insulation (JUSI)
into the Wall Thimble. See separate installation instructions
packaged with the JUSI.

A Wall Thimble will be required when passing through a combustible wall
and will accomodate a wall thickness up to 8-3/4" (see Figure 16). After
