F. Install Metal Roof Flashing
• See minimum vent heights for various pitched roofs
(Figure 10.11) 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 10.12.

CAULK
NOTICE:
Failure to properly caulk the roof flashing and
pipe seams could cause water entry.
• Caulk the gap between the roof flashing and the outside
diameter of the pipe.
• Caulk the perimeter of the flashing where it contacts the
roof surface. See Figure 10.12.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
G. Assemble and Install Storm Collar
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during instal-
lation. Sheet metal edges are sharp.
• Connect both halves of the storm collar with two screws
(see Figure 10.13).
• Wrap the storm collar around the exposed pipe section
closest to the roof and align brackets. Insert a bolt
(provided) through the brackets and tighten the nut to
complete the storm collar assembly. Make sure the collar
is tight against the pipe section.
• Slide the assembled storm collar down the pipe section
until it rests on the roof flashing (see Figure 10.14).
• Caulk around the top of the storm collar (see Figure 10.15).
