Vent Considerations
Twist-lock procedure:
Four indentations, located on the female ends
of pipes and fittings, are designed to slide straight onto the male ends
of adjacent pipes and fittings by orienting the four pipe indentations so
they match and slide into the four entry slots on the male ends (see
Figure 14). Push the pipe sections completely together, then twist-lock
one section clockwise approximately one-quarter turn until the two sec-
tions are fully locked. The female locking lugs will not be visible from
the outside on the pipe or fittings. They may be located by examining
the inside of the female ends.

Wall straps are available for this purpose.
Pipe Sealing:
required at only the first pipe joint attaching the pipe to the flue collar on
the fireplace. If Simpson Dura-Vent GS pipe is used, then the pipe must
be sealed as follows: seal both the inner and outer pipes with a high
temperature silicone sealant rated for at least 600º F (commonly known
as "RTV"). Run a 1/8" (3 mm) bead of silicone around the outside of the
male end of the outer sleeve. Run a 1/8" (3 mm) bead of silicone about
1/4" (6 mm) from the end of the male inner pipe, which is found in the
pipe to be attached above. Twist-lock the pipes or fittings together.
