CAUTION!
Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during instal-
lation. Sheet metal edges are sharp.
• Slide the storm collar onto the exposed pipe section
and align brackets.
• Insert a bolt (provided) through the brackets and install
nut. Do not completely tighten.
• Slide the assembled storm collar down the pipe section
until it rests on the roof flashing. See Figure 7.12.
• Tighten nut and make sure the collar is tight against the
pipe section.
• Seal around the top of the storm collar. See Figure 7.13.
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 7.11.
•
Use an elastomeric or silicone sealant with a minimum of
150 ºF temperature rating to seal the metal roof flashing.
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 7.11.
• Seal the exposed pipe section seams that are located
above the roof.
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.
