Securely fasten the vent pipe joints
according to the following procedure.
1. Insert the male end into the female
section. Push the units together and turn
them until the bead of the male end is
seated against the flared end of the
female
section. This creates the
necessary airtight seal. Align the seams
on the vent lengths and orient them
upward in all horizontal applications.
2. Tighten the locking band with a nut
driver until snug plus 1/4 turn.
Before proceeding, recheck all joints and
ensure that all male sections extend to the
top of the flared female end and all clamps
are tightened.
Figure 9 - Correct Vent Pipe Connection
Stop bead on male end must be pushed
