Assemble Minimum Installation (MI) Sections
MI sections are non-unitized so that they can be cut to a
certain length. Cut these sections to length from the non-
expanded end (see Figure 8.5).
They can then be attached by
fi
rst connecting the expanded
end of the MI inner
fl
ue with the inner pipe from the adjacent
pipe section and securing with three screws. The expanded
portion of the MI inner
fl
ue must overlap completely with the
unexpanded end of the adjacent pipe section.
The outer
fl
ue can then be inserted into the adjacent outer
fl
ue expanded end and attached to the next pipe section with
three screws. The other end of the MI pipe section can then
be attached by
fi
tting another pipe section to it and snapping
it together, as normal.
Assemble Slip Sections
The outer
fl
ue of the slip section should slide over the outer
fl
ue of the pipe section and into (inner
fl
ue) the last pipe sec-
tion (see Figure 8.6) .
Slide together to the desired length, making sure that a
1-1/2 in. outer
fl
ue overlap is maintained between the pipe
section and slip section.
The pipe and slip section need to be secured by driving two
screws through the overlapping portions of the outer
fl
ues
using the pilot holes (see Figure 8.7).
This will secure the slip section to the desired length and
prevent it from separating. The slip section can then be at-
tached to the next pipe section.
If the slip section is too long, the inner and outer
fl
ues of the
slip section can be cut to the desired length.
