¹⁄₄
" x 10" (8.3 x 25.4 cm) rectangular or 6" (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 lengths of
each vent piece used in the system. See the following examples:
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.
