V+H ≤ 40 ft. (For longer vent runs,
a power vent is required).
H ≤ 20 ft.

centre of vent elbows. Elbows are
considered as 90º.
Two 45º elbows = One 90º elbow.

A 6’ minimum vertical rise
is considered the minimum
practical dimension for the
specific appliance enclo-
sure and a minimal build-
ing structure. However, a
greater minimum vertical
rise may be needed to suit
the specific application
constraints or local codes
and / or regulatory require-
ments.
