ashing over the pipe sections extending
through the roof as shown in Figure 10.15.

NOTICE:
Failure to properly caulk the roof
fl
ashing could
cause water entry.
• 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 10.15.

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.
• 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
fl
ashing (see Figure 10.16).
• Tighten nut and make sure the collar is tight against the
pipe section.
• Caulk around the top of the storm collar. See Figure 10.17.
