PENETRATING ROOF
To maintain a 1" 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 the
distance the roof drops over a given span,
usually 12". A 6/12 pitch means that the
roof drops 6" for each 12" one measure
horizontally down from the roof rafters.
3. Use roof opening chart (Figure 12, page
10) to determine the correct opening
length and flashing required.
4. Remove the shingles around opening
measured. Cut out this section.
5. Add next sections of pipe until end pen-
etrates roof line. Check to see that the
proper clearances are maintained. Extend
chimney by adding sections of double wall
pipe until pipe is minimum of 30" above the
highest point of the roof cutout. Termination
and chimney must extend a minimum of
36" above the highest point where it passes
through the roof.

FLASHING INSTALLATION (V6F-8DM
OR V12F-8DM)
Determine the flashing to be used with the 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 nail-
ing 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 the
flashing and roof. The flashing must be secured
to the 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.

Storm Collar Installation (SC1 or SC2)
Place storm collar over pipe and slide down
until it is snug against the open edge of the
flashing (see Figure 14). Use SC1 for all round
terminations and SC2 for all terminations with
slip sections. Apply waterproof caulk around the
perimeter of the collar to provide a proper seal.
