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 horizontally down from roof rafters.
3. Use roof opening chart (Figure 15, page 12) to determine correct
opening length and flashing required.
4. Remove shingles around opening measured. Cut out this section.
5. Add next sections of pipe until end penetrates roof line. Check
to see that proper clearances are maintained. Extend chimney by
adding sections of double wall pipe until pipe is minimum of 30"
above highest point of roof cutout. Termination and chimney must
extend a minimum of 36" above highest point where it passes
through roof.
