D. Installing Roof Flashing and
Vertical Termination Cap
To install roof
À
ashing see Figure 8.16.
For installation of vertical termination cap see minimum vent
heights for various pitched roofs (see Figure 8.16) .
Caulk the gap between the roof
À
ashing and the outside
diameter of the pipe. Also caulk the perimeter of
À
ashing
that contacts roof surface as shown in Figure 8.18
To attach the vertical termination cap, slide the inner col-
lar of the cap into the inner
À
ue of the pipe section and
place the outer collar of the cap over the outer
À
ue of the
pipe section.
Secure with three screws into the outer
À
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
À
ue of the pipe (see Figure 8.17).
