ASSEMBLY
The ends of each inner pipe are made of flanges (1/2"). All the
joints between sections are a flange-to-flange connection of
the inner pipe.
SPECIAL FEATURE
All sections have an unattached "Alignment Sleeve".
The alignment sleeve facilitates centering of adjacent sections
and provides 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

STEP 3:
Join the two flanged ends of the duct section together and
rotate slightly to ensure complete coverage of the sealant on
flanges.
Figure 14: Joint Assembly step 3
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 ducts
NOTE: light tapping with a hammer all around the
band while tightening bolts helps align and pull
flanges together.

STEP 5:
Install the supplied AES insulation strips between sections to
ensure that all gaps are filled. Be sure that insulation is tightly
packed and completely fills the void between flue and closure
band when assembled
