Range hood knockouts

civ_IV_fanJune 27, 2013

I'm looking at buying a used range hood. Trouble is, the last owner had a rear-duct installation and I have a top-duct installation. So the rear 3 1/4" x 10" knockout is punched out. Would it be a big deal to merely cover this with something or will it screw up the air flow in some way that I'm not thinking of?

Thank you for reporting this comment. Undo

I don't think it should be a problem as the wall is going to cover the knockout?

I would post a shout out thread to KAS in the Appliance Forum. He is the ventilation expert on the AF.
