G. Assemble and Install Storm Collar
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during
installation. Sheet metal edges are sharp.
• Connect both halves of the storm collar with two screws
(see Figure 8.13).
• 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 fl ashing (see Figure 8.14).
• Caulk around the top of the storm collar (see Figure 8.15).

NOTICE: Failure to properly caulk the roof fl ashing and
pipe seams may permit entry of water.
• Caulk the gap between the roof fl ashing and the outside
diameter of the pipe.
• Caulk the perimeter of the fl ashing where it contacts the
roof surface. See Figure 8.12.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
