FLASHING INSTALLATION (V6F-10DM
OR V12F-10DM)
Determine the flashing to be used with the
roof opening chart. Slide flashing over pipe
until base is flat against roof. Replace as
many shingles as needed to cover exposed
area and flashing base. Secure in position by
nailing through shingles (see Figure 15). DO
NOT NAIL THROUGH FLASHING CONE.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down
until it is snug against the open edge of the
flashing (see Figure 16). Apply waterproof
caulk around the perimeter of the collar to
provide a proper seal.

Installing Flashing on a Metal Roof
When installing the flashing on a metal roof,
it is required that putty tape be used between
the flashing and the roof. The flashing must be
secured to the roof using #8 x 3/4" screws and
then sealed with roof coating to prevent leak-
age through the screw holes. A roof coating
must also be applied around the perimeter of
the flashing to provide a proper seal.
