inner flex pipe from the Vertical termination kit over the flex
adapter ensuring that the inner flex pipe overlaps the collar by at
least 1.4" (35 mm). Fasten with 3 screws.

If an offset is necessary in the attic or floor joists
it is important to support the vent pipe every 3 ft.
(0.91 m) to avoid excessive stress and sagging of
the vent pipe. Wall straps are provided (3 in total)
for this purpose.
All round/plumbers strapping may also be used if
further supports are required.
