H. 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 10.16).
• 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 10.17).
• Caulk around the top of the storm collar (see Figure 10.18).
Figure 10.16 Assembling the Storm Collar
Figure 10.17 Assembling the Storm Collar Around the Pipe
NOTICE: Failure to properly caulk the roof flashing and
pipe seams may permit entry of water.
• 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 10.15.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
