FIRESTOP SPACERS (FS-10,
1100EFS-10DM FOR 36" MODELS)
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 13.
They also provide complete separation from
one floor space to another or attic space as
required by most codes. When the double wall
pipe passes through a framed opening into an
attic space, the firestop must be placed into an
attic floor as shown in Figure 14.

PENETRATING ROOF
To maintain a 1" (36" Models) or 2" (42/50"
Models) clearance to the pipe on a roof with a
pitch, a rectangular opening must be cut.
1. Determine center point through which pipe
will penetrate roof.
2. Determine center point of roof. Pitch is
distance the roof drops over a given span,
usually 12". A 6/12 pitch means that roof
drops 6" for each 12" measured horizon-
tally down from roof rafters.
3. Use roof opening chart (Figure 15, page
11) to determine correct opening length
and flashing required.
4. Remove shingles around opening mea-
sured. Cut out this section.
