Offset Through Floor/Ceiling - Superior CUSTOM SERIES CR-3835L Installation Instructions Manual

CHIMNEY 30 OFFSET THROUGH FLOOR
OR CEILING
It may be necessary to assemble the chimney at
30 when passing through the floor or ceiling
area. Use the F8FS30-2 firestop spacer as shown
in Figures 22 and 23 . Support the chimney at
floor or ceiling penetration with a FTF8 stabi-
lizer if distance of chimney below ceiling is 10'
or more. Maintain 2" minimum air space to
combustibles from chimney sections.

Step 4. Note: Chimney sections are constructed
with a unique locking tab design, which en-
sures an immediate, tight assembly between
sections. 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.
Security's FTF8 and FTF10 chimney systems
are two piece chimneys, which snap 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 preceding 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 the next section.
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 24 ).

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 25 ).

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 26 ).
** Note: 1" (25 mm) when installed with FTF10
in the U.S. only.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Always maintain 2" (51 mm) minimum air space
to combustible materials and always check
each chimney joint (inner and outer) to ensure
proper engagement ( See **Note ). Check verti-
cal alignment of chimney so that it projects
from the roof in true vertical position.
Figure 26
Security's chimney sections do not need to be
screwed together. Additional reinforcement is
not necessary except in certain offset condi-
tions (refer to page 14, Figure 37 ).
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 F8-S4 or
Model F10-S4 stabilizer installed at 30' (9.1 m)
intervals.
Note: The Model F8-S4 and Model F10-S4 add
3" (76 mm) net effective height to the total
chimney system.

fitting inner section down into respective sec-
tion of proceeding flue pipe and locking outer
stabilizer section into place over the outer
chimney pipe. Position for proper clearance
through framed opening and nail straps se-
curely (under tension in "shear") into place on
framing. Use 8d nails. Attach successive
lengths of chimney pipe directly to stabilizer
using same techniques as described in Step 4
( Figure 27 ).
