A:
Yes, this unit can be outside vented from the top or the
rear of the case. You remove one of 2 covers if you
want to vent outside.
You must cut a 3"x10" hole in the wall (rear vent)
or cabinet (top vent) to vent this way. You can then
convert to a 3" or 4" round vent hose if desired.
The default vent is out the top front of unit into the
kitchen. No modification necessary.
