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

Figure 13 - Flashing Installation
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
Figure 14). Apply waterproof caulk around the
perimeter of the collar to provide a proper seal.

Instructions for chase installations are included
with the chase style termination chosen. In a
multiple chase installation, be sure to provide
adequate distance between terminations to prevent
smoke spillage from one termination to another.
We suggest that terminations be separated at least
24" center to center and stacked at a vertical height
difference of 18" (see Figure 16, page 10).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specications.
