clearance (air space) of 1 inch
between the Pipe and construc-
tion materials. Straight lengths
of pipe are run up above the
roof. (see table 2) A Roof Flash-
ing is placed down over the
pipe, and adjusted so it fits
tightly against the roof, with the
Pipe Section held in a position
maintaining the 1 inch minimum
clearance from combustibles.
The Flashing is then nailed to
the roof. The roofing material
(shingles, asphalt paper, etc.)
should overlap the top edge (up-
hill side) of the Flashing. A
non-hardening sealant should be
used around the edges of the
flashing base where it meets the
roof, as shown in Figure 12.
Non-hardening sealant is placed
around the joint between the
Flashing and the vertical Pipe
Section and the Storm Collar is
then placed over this joint, to
make a watertight seal. Add
sufficient Pipe Sections to at-
tain the height specified in Table
2. To connect the Top to the
pipe, hold Top by its collar,
slide collar over locking lugs of
pipe, and twist-lock clockwise.
Tops of diameters greater than
16 inches do not twist-lock, but
are affixed with sheet metal
screws.
