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 10.10.

•Caulk the overlap seam of any exposed pipe sections that are located above the roof line.

E. 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 10.11).

•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 10.12).

•Caulk around the top of the storm collar (see Figure 10.13).
