NOTICE: The installation of a firestop thimble (FST30
or 38FST) is recommended when negotiating a joist
and to prevent intrusion from insulation.

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 the 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 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.

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 13). 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.
