17. To attach the vent connections at the replace, be sure the 7”
diameter adapter collar has been installed per step 3. Apply a
bead of silicone sealant to the 4” diameter ex connector, then
slide the ex pipe adapter collar into the replace ue collar
and secure by installing a minimum of two (2) screws through
the ue collar and into the adapter. See Figure 39.
18. Apply sealant to the 7” diameter adapter collar, slide outer
ex vent over the collar, then secure with a 7” diameter band
clamp. See Figure 39.
19. Once the lower connections are made and the ex pipe is
secured with support bands as required (3 feet minimum be-
tween supports) then the roof ashing can be installed. See
Figure 40.
20. Install the roof ashing, and seal using common constructions
practices.
21. An additional storm collar band is provided in kit that may be
used as an attic insulation shield. The collar can be installed
around the ex pipe (or hard pipe) just above the restop
thimble. This collar will act as a shield to prevent blown insu-
lation from entering the thimble.
22. To complete the vent installation, install the vent termination
cap to the top of the hard vent pipe assembly. Mate up the
ue and outer telescopes with the hard pipe assembly, then
secure by installing a minimum of two (2) sheet metal screws
into the overlapped anges of the cap and pipe.
23. Figure 41 shows a completed installation with components
identied and other installation information such as heights
and clearance to combustibles.
