Thank you for your question on the model AEN80 exhaust fan. The AEN80 can be installed in the ceiling and be vented horizontally using four inch, preferably rigid duct work, to the outside. You can install this product in the wall if it is mounted 8 foot or more above the floor and the walls are thick enough. The housing is 5-3/4 inches deep. If mounted in a wall, it may be difficult venting out of the same wall. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
