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.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down
until it is snug against open edge of flashing
(see Figure 14). Apply waterproof caulk around
perimeter of collar to provide a proper seal.

CHASE INSTALLATIONS
Instructions for chase installations are includ-
ed with the chase style termination chosen.
In a multiple chase installation, be sure to
provide adequate distance between termi-
nations to prevent smoke spillage from one
termination to another. Terminations must be
separated a minimum of 24" center to center
and stacked at a minimum vertical height dif-
ference of 18" (see Figure 16, page 10).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specifications.
