FIRESTOP SPACERS (3600FS-8DM-1)
Firestop spacers are required at each point where the chimney penetrates a
floor space. Their purpose is to establish and maintain the required clearance
between the chimney and the combustible materials. When the pipe passes
through a framed opening into a living space above, the firestop must be
placed onto the ceiling from below as shown in Figure 17.

as needed to cover exposed area and flashing base. Secure in position
by nailing through shingles (see Figure 18). DO NOT NAIL THROUGH

Installing Flashing on a Metal Roof
When installing flashing on a metal roof, it is required that putty tape be
used between flashing and roof. Flashing must be secured to roof using
#8 x 3/4" screws and then sealed with roof coating to prevent leakage
through screw holes. A roof coating must also be applied around the
perimeter of flashing to provide a proper seal.
