FLASHING INSTALLATION (V6F-8DM
OR V12F-8DM)
Determine the ashing to be used with the roof
opening chart. Slide ashing over pipe until base
is at against roof. Replace as many shingles as
needed to cover exposed area and ashing base.
Secure in position by nailing through shingles
(see Figure 13). DO NOT NAIL THROUGH
FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the ashing on a metal roof, it is
required that putty tape be used between the ashing
and the roof. The ashing must be secured to the roof
using #8 x 3/4" screws and then sealed with roof coat-
ing to prevent leakage through the screw holes. A roof
coating must also be applied around the perimeter of
the ashing 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 ashing (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.
