Determine the flashing to be used with the roof open-
ing chart. Slide flashing over pipe until base is flat
against roof. Replace as many shingles as needed
to cover exposed area and flashing base. Secure in
position by nailing through shingles (see Figure 21).
DO NOT NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is re-
quired 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 leakage through the screw holes.
A roof coating must also be applied around the pe-
rimeter 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
22). 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 multiple
chase installation, be sure to provide adequate dis-
tance between terminations to prevent smoke spill-
age 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 24, page 17).
