When installing the ashing on a metal roof, it is
required that putty tape be used between the ash-
ing and the roof. The ashing 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 ashing to provide a
proper seal.

Place storm collar over pipe and slide down until
it is snug against the open edge of the ashing (see

with the chase style termination chosen. In a mul-
tiple chase installation, be sure to provide adequate

nations be separated a minimum of 24" center to
center and stacked at a minimum vertical height
difference of 18" (see Figure 16).
Note: If a decorative shroud is to be installed,
