Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is
required that putty tape be used between the flash-
ing 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 leakage 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 the open edge of the flashing (see
Figure 14). Apply waterproof caulk around the
perimeter of the collar to provide a proper seal.

CHASE INSTALLATIONS
Instructions for chase installations are included
with the chase style termination chosen. In a mul-
tiple chase installation, be sure to provide adequate
distance between terminations to prevent smoke
spillage from one termination to another. Termi-
nations be separated a minimum of 24" center to
center and stacked at a minimum vertical height
difference of 18" (see Figure 16).

If a decorative shroud is to be installed,
