(15.2 cm) round vent
should be used.
The total length of the vent system including straight vent,
elbow(s), transitions and wall or roof caps must not exceed the
equivalent of 140 ft (42.7 m) for either type of vent. See
“Recommended Standard Fittings” section for equivalent lengths.
For best performance, use no more than three 90° elbows.
To calculate the length of the system you need, add the equivalent
length for each vent piece used in the system. See the following
examples:

" x 10" (8.3 x 25.4 cm) vent system = 73 ft (22.2 m) total
6" (15.2 cm) vent system = 73 ft (22.2 m) total
If the existing vent is round, a rectangular to round transition piece
must be used. In addition, a rectangular 3" (7.6 cm) extension vent
between the damper assembly and rectangular to round transition
piece must be installed to keep the damper from sticking.
