Vertical Termination Requirements - Majestic QUARTZ Series Installation Manual

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 7.12.
• 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. Climate regions with
frequent temperatures below - 50 °F (-45.6 °C) should use a
silicone flashing 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 7.12.
• Seal the exposed pipe section seams that are located
above the roof.
