Rear Vent Configuration with Vertical Termination
The termination must fall
within the shaded area shown
in the chart. Use the
indicated restrictor and
diffuser positions.
Up to four elbows (45° or 90°)
may be used.
Only one horizontal elbow
may be used.
This is considered a horizontal
elbow (it does not matter
whether it turns right or left).
It may be a 90° or 45° elbow.
