Refer to the venting instructions included with your termi-
nation kit for more detailed instructions.
Caulk the gap between the roof fl ashing and the outside
diameter of the pipe. See Figure 8.5. Also caulk the pe-
rimeter of fl ashing that contacts roof surface. The storm
collar is then placed over this joint to make a water tight
seal. See Figure 6. Caulk around the joint between the
storm collar and the vertical pipe.
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.
