and seal with a non-hardening sealant, as shown in Figure 17. Seal all nail

heads.

5. Height. Add sufficient Pipe Sections of B-Vent until the system

terminates 1-1/2" to 3" above the collar of the Flashing as shown in Figure 16.

6. Top Cone. Slip the Top Cone over the Flashing, so the vertical straps

on the Flashing coincide with the slots at the base of the Cone. Slip the straps

up through the slots as shown in

Figure 18. Adjust the Top Cone to

a generally vertical position.

Holding the Top Cone in position,

bend the straps down as shown.

sealed nail heads, etc.

concerning Adjustable Elbows, both 90° and 45°/60°.

2. Connections. In addition to twist locking the elbows, the connection may

be further secured by using sheet metal screws at the joint where the male and

female parts overlap, provided that the screws do not penetrate the inner liner

as shown in Figure 19. One screw per joint is normally sufficient. Use #8 Pan

Head sheet metal screws which are no longer

than 1/4 inch. Liberal use of Wall Straps for

additional support is recommended. Do not

allow the weight of the offsetting pipe to bear

down on lower elbow.

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
