NOTE:
 Galvanized pipe is desirable above the roofline
due to its higher corrosion resistance. Continue
to add pipe sections throughout the flashing
until the height of the vent cap meets the mini-
mum height requirements specified in Fig. 5. or
local codes.
 For steep roof pitches, the vertical height must
be increased. A poor draft, or down drafting
can result in high wind conditions, trees or
neighbor's roof lines. In these cases, increas-
ing the height may solve a drafting problem.
REMEMBER to check that you are within the
maximum vertical height restrictions, and are
placing the appropriate vent restrictors as out-
lined in the venting chart within this manual.
 Any storage spaces or closets which the vent
must pass through must be enclosed.
