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 23 and 24 . 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.

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

Note: For Canadian installations, all chimney
installed outside the building must be constructed
with galvalume (outer sections only) effective
January 1, 1992. The appropriate model desig-
nations are located in the back of this manual.
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
carefully before assembly as chimney is diffi-
cult to disassemble after installation. If disas-

certain tabs are properly formed to ensure
locking tabs engage properly.
The Security FTF8 chimney system is a two

place. At all subsequent joints, the upper
flue section fits into the preceding flue sec-
tion. 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 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 pen-
etrate the roof flashing openings ( Figure 28 ).
Always maintain 2" minimum air space to com-
bustible materials and always check each chim-
ney joint (inner and outer) to ensure proper
engagement. Check vertical alignment of chim-
ney so that it projects from the roof in true
vertical position.
