used to support each elbow (Figure 10). Do
not allow the elbows to support the weight of
the vent pipe.
3. 90° Elbows. Figure 20. The installer
should apply pressure to the section at the
points indicated by the arrows. This will
prevent the adjacent sections of the elbow
from turning, as the next pipe or fitting is twist-
locked on. This is important, because once
these sections start rotating, the elbow does
no longer have a 90° angle.
4. 45° Offsets with 90° Elbows. Figure 21
shows a 90° adjustable Elbow being utilized
to accomplish a 45° offset. This Elbow is
completely adjustable from 0° to 90°. please
note that the centers of the upper sections
tend to displace by a slight amount, as they
are rotated. again, screws (not longer than
1/4”) may be used to secure the joint. Wall
Straps should also be utilized to enhance the
stability of the vent system.
