FLASHING INSTALLATION (V6F-8DM
OR V12F-8DM)
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 nail
-
ing through shingles (see Figure 13). DO NOT
NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing flashing on a metal roof, it is
required that putty tape be used between the
flashing and roof. The flashing must be secured
to the roof using #8 x 3/4" screws and then
sealed with roof coating to prevent leakage
through screw holes. A roof coating must also be
applied around perimeter of flashing to provide
a proper seal.

Storm Collar Installation (SC1 or SC2)
Place storm collar over pipe and slide down
until it is snug against the open edge of the
flashing (see Figure 14). Use SC1 for all round
terminations and SC2 for all terminations with
slip sections. Apply waterproof caulk around the
perimeter of the collar to provide a proper seal.
