opening is 3-1/4" x 10" (8.3 cmx 25 cm).
Vent system can terminate either through
the roof or wall. To vent through a wall,
a 90° elbow is needed.
The vent system length should not
exceed the lengths shown in the chart
below,

Note: Flexible vent is Not
recommended.
If it is used, each foot of flexible vent
used is equivalent to two feet
(61 cm) of straight metal vent when
calculating the vent system length,
(Example: A flexible elbow equals two
standard elbows,)
