required to connect the flexible vent assembly to the vertical termination by using three self-
penetrating screws.

2.  Review 

Figure 30

 and corresponding instructions for proper overlap, clamp and screw place-

ment.

3.  Three  each  self-penetrating  screws  are  drilled  opposite  one  another  and  below  the  gear 

clamp.

4.  Use only listed and approved terminations and accessories, installed per the installation instruc-

tions and 

Figure 29
