used to penetrate through the wall must extend
at least 6” into the room (Fig.24 & 27). Use
high-temperature sealant (500ºF) to seal
between the Wall Thimble and the Chimney on
the outer wall.
7. Install Cover Plate and Finishing Collar:
After the Chimney Branch is secured in place
(penetrating at least 6” into the room), slide
the Cover Plate over the Branch and attach
it to the framing using (4) 1-1/4” long, round
head wood screws. Be sure that the Branch
is centered in the opening of the Cover Plate.
Twist lock the Finishing Collar on to the
female end of the Chimney Branch by twisting
clockwise.
8. Complete Chimney: Attach the Chimney
Sections as in Step 7 in the Ceiling Supported
Installation section. Secure the chimney to
the wall with Wall Straps at a minimum of 8’
intervals and maintain at least 2” of clearance
to combustible materials. The various support
components are adjustable in length from
the wall to better t your installation. Slip the
Wall Straps around the chimney, tighten the
bolts, adjust the clearance, and fasten the Wall
Straps to the wall with (4) #8, 1-1/2” long wood
screws. Once the chimney is at the minimum
height specied in Fig.1, attach the Chimney
Cap onto the top of the chimney by holding
it by the collar and twist locking it clockwise
onto the Chimney Pipe. If the chimney
penetrates an overhang, frame for at least 2”
of clearance, and install Flashing and Storm
Collar as described in Steps 9 & 10 for “Ceiling
Supported” Installations. Another option is
to cut away the overhang for a 2” clearance
(Fig.28). If the chimney extends more than 5’
above the top Wall Strap or Flashing, use an
Extended Roof Support Bracket.
9. Install Chase Top Flashing: It is
recommended that a Tee Supported Chimney be
enclosed in a chase. If a chase enclosure has
been constructed, you can either use a standard
at-roof ashing, or you can use a Chase Top
