Figure 6.13. Vent Termination Diagram.
A maximum of two 90°
or four 45° elbows may
be used. Whenever
possible, use 45° elbows
instead of 90° elbows as
these offer less restriction
to the flow of flue gases
and intake air.
Reduce the overall
horizontal run by 5 feet
for each additional 45°
and 90° elbow.
When two or more
elbows are used in a
horizontal run, a less
restricted setting may
be more effective
than that indicated by
the termination zone
diagram.
Colinear Venting: Zone
A is reccommended for
all Co-linear vent runs.
