E. Vertical Termination Requirements
Install and Seal Metal Roof Flashing
• See minimum vent heights for various pitched roofs
(Section 4, Figure 4.1) to determine the length of pipe
to extend through the roof.
• Slide the roof flashing over the pipe sections extending
through the roof as shown in Figure 7.9.
• Use an elastomeric or silicone sealant with a minimum of
150 ºF temperature rating to seal the metal roof flashing.
Note: When installing a silicone or EPDM pipe flashing boot
on a metal roof, it is recommended to put a bead of 100%
silicone sealant where the boot contacts the vent pipe to
prevent the entry of water. Follow the manufacturer's recom-
mendations when installing the boot.
NOTICE: Failure to properly seal the roof flashing and pipe
seams could permit entry of water.
• Seal the gap between the roof flashing and the outside
diameter of the pipe.
• Seal the perimeter of the flashing where it contacts the
roof surface. See Figure 7.9.
• Seal the exposed pipe section seams that are located
above the roof.

• Slide the assembled storm collar down the pipe section
until it rests on the roof flashing. See Figure 7.10.
• Tighten nut and make sure the collar is tight against the
pipe section.
• Seal around the top of the storm collar. See Figure 7.11.
Install Vertical Termination Cap
• Attach the vertical termination cap by sliding the inner
collar of the cap into the inner flue of the pipe section
while placing the outer collar of the cap over the outer
flue of the pipe section.
• Secure the cap by driving three self-tapping screws
(supplied) through the pilot holes in the outer collar of
the cap into the outer flue of the pipe. See Figure 7.11.
