some vent thru the middle like Jenn Air, some can have a vent in the rear that is motorized and raises and lowers when turned on, some have no vent they are vented overhead, you should try to find one that is just like your old one, use the old vent system. if you have to run new vent it will get expensive, if you have lots of extra tiles to replace the ones you break changing the unit you my get off easy. if no extra tiles find a unit the same size as the old one. if you know nothing about setting and cutting tile. HIRE A PRO!
