(Fig 20)
. Depending on the thickness
of your wall, you will need to adjust the shield
extension to insure that you have a continuous
shield throughout the wall penetration.
Adjustments can be made by sliding the
extension in or out of the back portion of the
shield. Verify that the shield extension reaches
the front cover plate when the cover plate is
in position. Do not install cover plate at this
time. When the shield extension is in position,
secure it to the back portion of the shield using
(4) sheet metal screws
(Fig 20)

4. Install Tee Support:
Install the Tee
Support on the outside wall. Position Tee
Support so that the chimney Tee will be
centered inside the Wall Thimble
(Figs 19 &

. Important: Verify that Tee Support is level,
then secure Tee Support to outside wall using
(3) 1/4”x 2” long lag screws for the support
base, and (8) #8, 2-1/2” wood screws for the
brackets (2 screws per bracket). Be sure to
keep the Tee Support level.
5. Install Chimney Tee and Branch:
Attach the Chimney Branch to the Tee. The
Chimney Branch is 12” or 18” Chimney Section
(depending on your wall thickness) positioned
horizontally used to pass through the wall.
Important:
The Chimney section used to
penetrate through the wall must extend at
least 6” into the room. Secure the Chimney
Branch to the Tee by using the (6) sheet metal
screws provided. It is very improtant that a
good connection is made between the Branch
and the Tee.

Install the Tee Cap
in the bottom of the Tee, on the underside of
the Tee Support Bracket. Be sure that the Tee
Cap is securely inserted into the bottom of the
chimney pipe. Secure the Tee Cap in place by
attaching the Tee Cap Retainer Bar using the
two (2) bolts included
