Step 7.
Slip the Roof Flashing over the Pipe
Section(s) protruding through the roof. Use a non-
hardening sealant between the Roof Flashing and
the roofing to prevent water leakage. Secure the
base of the Roof Flashing to the roof with roofing
nails. Ensure the roofing material overlaps the top
edge of the Roof Flashing (Fig. 18). Verify that you
have at least the minimum clearance to combus -
tibles at the roof line and in the attic.
Step 8.
Continue to add Pipe Sections until the
height of the system (before adding the Cap)
meets the minimum building code requirements
as described in (Table 3 and Fig. 17). Note that
for steep roof pitches, the vent height must be
increased. In high wind conditions, nearby trees,
adjoining roof lines, steep pitched roofs, and other
similar factors can result in poor draft, or down
drafting. In these cases, increasing the vent height
or switching to the High Wind Termination Cap
may help to solve the problem.
Step 9.
Slip the Storm Collar over the Pipe Sec -
tion, and push it down to the top of the Roof Flash -
ing (Fig. 18). Use non-hardening sealant between
the Storm Collar and the Pipe Section.
Step 10.
Holding the bottom of the Termination
Cap only, twist lock the cap onto the last Pipe Sec -
tion protruding above the roof line.
Notes:
(1) For multi-story vertical installations, a Ceiling
Firestop is required at the second floor, and any
subsequent floors (Fig. 19). Refer to Table 1, page
8. Cut and frame a square opening for installation
of the Ceiling Firestop.
(2) If Vent passes through any occupied areas
above the first floor, including closets and stor -
age spaces, it must be enclosed. The enclosure
may be framed and sheet rocked with standard
construction materials, but required 1" clearance
to combustibles must be maintained. Do not fill
required air spaces with insulation.
(3) If venting system passes through an attic
space the Attic Insulation Shield or a chase en -
closure must be installed to prevent contact be -
tween Pipe Sections and the insulation or other
debris. For the Attic Insulation Shield, nail the base
to floor of attic and adjust shield for appropriate
insulation level, then attach the collar at the top of
assembly (Fig. 19).
