oven exhaust fan
I'm replacing my exhaust fan for the oven so I can vent it outside. My oven isn't on a outside wall. I had planned on running a 3 by 10 vent straight up thru the cupaboard, us a right angle boot to a round duct and run that across the cupboards (8 feet) to the outside wall.
My question is what size would you want the round vent at? a 3*10 vent is 30 sq inches, to get the same in a round vent I would have to go to a 6 inch vent. Thats big, too big for me, I would perfer a 4 or 5 inch vent.
