Expansion Joints Installation
Bellows Joint and Expansion Length in vertical runs
1.
A Bellows Joint or Expansion Length installed vertically should be installed directly below the highest support or one pipe length below,
between fixed points. See
Figure 36 - 37
2.
Always use Bellows Joints or Expansion Lengths between fixed points when expansion is over 1/4”. See
Table 6 and 7
for maximum run
between fixed points.
3.
Install proper guiding between fixed points when using Bellows Joints or Expansion Lengths, to allow chimney vertical movement due to
expansion.
Bellows Joint and Expansion Length in horizontal runs
1.
Same guidelines apply as for vertical run with respect to expansion estimate and proper support and guiding with the use of Bellows Joints
or Expansion Lengths. See
Figure 36 - 37
Adjustable Lengths
The Adjustable Lengths (A1 and A2) serves two major functions: 1) to make up
for odd lengths of pipe in short runs, and 2) to provide for joint sealing. This part
adjusts to a needed fixed exact length. Its internal joint must be sealed by
working sealant under the compression band, as well as between the flanges to
be secured by bolts. Observe all precautions for cleaning sealed surfaces and
use proper sealant as described in the
Sealant Application Chart
section (see
Table 4
). It can be used in horizontal or vertical runs and also between elbows.
This part does not serves as an expansion joint.
Installation :
1.
Install the Lower Liner Assembly into the lower pipe section. See
Chimney Joint Connection
Section for joint assembly instructions.
2.
Position the Compression Band and Flange around the Upper Liner
Section
Figure 34
3.
Insert the Upper Liner Section into the Lower Liner Assembly.
Position and install the upper part (Length, elbow, support, etc) that
will go above the adjustable length.
4.
Connect the Upper Liner Section to the upper pipe section. See
Chimney Joint Connection
Section for joint assembly instructions.
5.
Apply 2 beads of sealant all around the upper liner section. The first
one 1" above the bottom flange and the second right where the inner
liner meets the lower flange (see
Figure 35
)
6.
Slide the compression band in its place over the first bead of sealant.
Tighten the flanges with the supplied bolts. Use a star tightening
pattern of the bolts for better stability. Tighten the compression band
bolts. Do not remove the excess of sealant.
7.
Install Insulation Pad (if necessary) and cover with 2 Outer Casing
Half Shields screwed into each other. Outer Shields may be cut to
length if required.
