SECTION C - PIPE & FITTING JOINT ASSEMBLY
The ends of each inner pipe are made of flanges. All the joints between sections are a flange-
to-flange connection of the inner pipe.
CAUTION: SHARP SHEET METAL, RISK OF CUTS WITH SLEEVES AND SECTIONS.
SPECIAL FEATURE
All sections have an unattached alignment sleeve (See figure 5).
Figure 5 - Feature of the alignment part
The alignment sleeve facilitates centering of adjacent sections and provides a backing for the
sealant applied to the flange keeping the sealant in the intended location. Typically, it is inserted
in the downstream end but may be removed. Although not required, it aids in easier assembly,
better sealing and adds strength to the section joint.

JOINT ASSEMBLY
STEP 1
Fill the channel of the inner V-Band (BSI) with the right Sealant, depending on flue gas
temperature (refer to SEALANT USAGE section for proper sealant selection) and install
below flange of first pipe section.
NOTE:
Sealant is supplied by Security and individual tubes are marked
S-2000 or S-650. See TABLE 6 for number of tubes per joint.
CAUTION: THE USE OF ANY OTHER SEALANT IS NOT RECOMMENDED, MAY VOID
CERTIFICATION AND MAY IMPAIR THE SEALING EFFECTIVENESS.
STEP 2
Apply a continuous bead of S-2000 or S-650 sealant 1/4" wide to one of the flanges
to be joined.
STEP 3
Join the two flanged ends of
the duct section together and
rotate slightly to ensure complete
coverage of sealant on flanges.
STEP 4
Install the V-Band around the
flanges making sure the flanges
are located within the V-Clamp.
NOTE: Do not locate V-Band
hardware at the bottom side of
horizontal duct joints.
NOTE: Light tapping with a
hammer all around the band
while tightening bolts helps align
and pull flanges together.
STEP 5 (DIS PRO ONLY)
Install the supplied insulation
strips between the sections to
ensure that all air gaps are filled.
Be sure that insulation is tightly
packed and completely fills the
void between flue and closure
band when assembled
