Venting
Note:
The intake
damper positions
specified in this
chart were set in a
controlled testing
environment, and
serve as a general
guideline for
installations. Every
venting configuration
is different, and the
damper setting may
need slight
adjustment from this
chart.
Note:
The vent must
not exceed a total
length of 35 feet.
Any combination of
rise and run may be
used but must be
constrained to the
boundaries of this
chart. A Maximum of
three 90° elbows
may be used. Only
one (1) 90° elbow or
combination of other
elbows equalling 90°
can be used without
reducing horizontal
run. For each
additional 90° elbow,
or an equal
combination of
elbows, reduce
horizontal vent run
by 2 feet. Ensure
vent pipe is properly
supported.
