Installing the Firestop Spacer
CAUTION:
Firestop spacers must be used whenever the
chimney penetrates a ceiling/floor area.

Assembling Chimney
Sections
WARNING!
Carefully follow the instructions for assembly
of the pipe and other parts needed to install this
fireplace system. Failure to do so may result in
a fire, especially if combustibles are too close
to the fireplace or chimney and air spaces are
blocked, preventing the free movement of
cooling air.
4. Assembling Chimney Sections
Attach either a straight chimney section or an offset
to the top of the fireplace (depending on your
installation requirement). Chimney sections are
locked together by pushing downward until the top
section meets the stop bead on the lower section.
The inner flue is placed to the inside of the flue section
below it. The outer casing is placed outside the outer
casing of the chimney section below it. See Figure 8.
5. Installing Firestop Spacers
Mark and cut out an opening in the ceiling for the
firestop spacer being utilized (14½” x 14½” for an
FS338, 14½” x 18 3 /
8
” for an FS339 and 14½” x 23”
for an FS340). Frame the opening with the same
dimension lumber used in the ceiling joists.
Install the firestop spacer.
These firestop spacers are designed to provide the
minimum 2” air space required around the chimney.
In all situations, the firestop spacers are to be
nailed to the ceiling joists from the bottom or
fireplace side, EXCEPT when the space above is an
insulated ceiling or attic space. In this situation, the
firestop spacer must be nailed from the top side to
prevent loose insulation from falling into the
required 2” air space around the chimney. See
Figure 9.
