To install roof fl ashing see Figure 8.13.
For installation of vertical termination cap see minimum
vent heights for various pitched roofs (see Figure 8.13).
Caulk the gap between the roof fl ashing and the outside
diameter of the pipe. Also caulk the perimeter of fl ashing
that contacts roof surface as shown in Figure 8.15.
To attach the vertical termination cap, slide the inner col-
lar of the cap into the inner fl ue of the pipe section and
place the outer collar of the cap over the outer fl ue of the
pipe section.
Secure with three screws into the outer fl ue. Secure the cap
by driving the three self-tapping screws (supplied) through
the pilot holes in the outer collar of the cap into the outer
fl ue of the pipe (see Figure 8.14).
