PENETRATING ROOF
To maintain a 2" clearance to the pipe on a roof with a pitch, a rect-
angular 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 14) 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-10DM OR V12F-10DM)
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 nailing through shingles (see Figure 15). DO NOT NAIL
THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is required that putty
tape be used between the flashing and the 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 the screw holes. A roof coating
must also be applied around the perimeter of the flashing to provide
a proper seal.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down until it is snug against
the open edge of the flashing (see Figure 16). Apply waterproof caulk
around the perimeter of the collar to provide a proper seal.
