FIRESTOP SPACERS (3600FS-8DM-1)
Firestop spacers are required at each point where chimney penetrates
a floor space. Their purpose is to establish and maintain required
clearance between chimney and combustible materials. When pipe
passes through a framed opening into a living space above, firestop
must be placed onto ceiling from below as shown in Figure 11.
They also provide complete separation from one floor space to an-
other or attic space as required by most codes. When double wall
pipe passes through a framed opening into an attic space, firestop
must be placed into an attic floor as shown in Figure 12.
If area above is a living space, install firestop
below framed hole.

If area above is an attic or insulated area, install
firestop above framed hole.

PENETRATING ROOF
To maintain a 1" clearance to pipe on a roof with a pitch, a rectangular
opening must be cut.
1. Determine center point where pipe will penetrate the roof.
2. Determine center point of roof. Pitch is the distance the roof
drops over a given span, usually 12". A 6/12 pitch means that
the roof drops 6" for each 12" measure horizontally down from
roof rafters.
3. Use roof opening chart (Figure 13) 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.

VENTING INSTALLATION Continued
FLASHING INSTALLATION (V6F-8DM OR V12F-8DM)
Determine flashing to be used with roof opening 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 14). DO NOT NAIL THROUGH
FLASHING CONE.
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 perimeter of flashing to provide a proper seal.
