K. 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 10.21).
•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 10.22).
•Caulk around the top of the storm collar (see Figure 10.23).

L. Install Vertical Termination Cap
•Locate and mark the flue center point on the underside of the roof, and drive a nail through the center point.
•Make the outline of the roof hole around the center point nail.
•The size of the roof hole framing dimensions depend on the pitch of the roof. There MUST BE a 1 in. (25 mm) clearance from the vertical flue pipe to combustible ma- terials.
•Mark the roof hole accordingly.
•Cover the opening of the installed flue pipes.
•Cut and frame the roof hole.
•Use framing lumber the same size as the roof rafters and install the frame securely. Flashing anchored to the frame must withstand heavy winds.
•Continue to install concentric flue sections up through the roof hole and up past the roof line until you reach the appropriate distance above the roof.
•Attach the vertical termination cap by sliding the inner collar of the cap into the inner flue of the pipe section while placing the outer collar of the cap over the outer flue of the pipe section.
•Secure the cap by driving three
