Superior TM-4500 Installation Instructions Manual page 9

For Canada Only
When installing the chimney system through
an open attic space, the attic shield assembly-
firestop spacer must be used ( Figure 25 ). This
installation procedure is Warnock Hersey Inc.
listed only for use in Canada.

Step 4. Note: Chimney sections are constructed
with a unique locking tab design which ensures
an immediate, tight assembly between sec-
tions. Plan your chimney requirements care-
fully before assembly as chimney is difficult to
disassemble after installation. If disassembled,
the tabs might become damaged. Be certain
tabs are properly formed to ensure locking tabs
engage properly.
The TF10 chimney system is two-piece chim-
ney, which snaps together from the fireplace
up. Start with the inner flue section. With the
lanced end up, snap-lock it into the matching
collar on top of the fireplace. At all subsequent
joints, the upper flue section fits into the pre-
ceding flue section. Each piece snaps together
by means of locking tabs (9 locking tabs per
joint). Check each piece by pulling up slightly
from the top to ensure proper engagement
before installing succeeding sections. If the
flue has been installed correctly, it will not
separate when you test it. Also, the inner flue
joint where each section is joined should be
tight and flat without gaps ( Figure 26 ).

Outer pipe section installs in just the opposite
way; the lanced end goes down and each new
section goes OVER the outside of the previous
section installed ( Figure 27 ).

Note: Assemble one component of chimney at
a time (inner section first, then outer section
last) before proceeding with the next complete
section.
Continue to assemble the chimney up through
framed opening. Assemble just enough to pene-
trate the roof flashing openings ( Figure 28 ).
Always maintain 2" (51 mm) minimum air space
to combustible materials and always check
each chimney joint (inner and outer) to ensure
proper engagement. Check vertical alignment
of chimney so that it projects from the roof in
true vertical position.

Superior chimney sections should not be
screwed together and it is not required for
additional reinforcement.
Step 5. The height of vertical chimney pipe
supported only by the fireplace must not ex-
ceed 30' (9.1 m) Chimney heights above 30'
(9.1 m) must be supported by a Model TF10-S4
stabilizer installed at 30' (9.1 m) intervals.
Note: The Model TF10-S4 adds 3" (76 mm) net
effective height to the total chimney system.
Install the Model TF10-S4 stabilizer by fitting
inner section into inner section of preceding
flue pipe and locking outer stabilizer section
into place over the outer chimney pipe. Position
stabilizer in framed opening retaining proper
clearance. Nail straps securely (under tension
in "shear") on framing use 8d nails.

Attach next chimney section directly to stabi-
lizer using same techniques as described in
Step 4.
Note: Do not apply excessive pressure to any
subsequent chimney sections following the
stabilizer when installing. Ensure each subse-
quent chimney section is securely attached by
testing as noted in Step 4.
Step 6. Select proper Superior roof flashing
based on pitch of roof. Use chart below for
selection:
Roof Pitch
Flat to 6/12
6/12 to 12/12
Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. Slide flashing all the
way down until the flashing base rests flat on
the roof. Again, check the vertical position of
the chimney and the 2" (51 mm) minimum air
space to combustibles.
Step 7. Secure flashing by nailing along the
perimeter into roof using 8d nails. If shingled
roof, slide upper end and sides of roof flashing
under shingles (trim if necessary), seal the top
and both sides of the flashing to the roof with
roof caulking. Cover nail heads with roof caulk-
ing ( Figure 30 ).
