The first time I saw this range, I immediately fell in love. My mind just started to conjure up images of it in my kitchen for some reason. But I do have a few questions. What does that tiny gap below the steel frame at the top back side do? Is it a vent? Does it suck heat or steam from the stovetop like the base of my OTR? I'm anxious to know because it seems like all components of this range have a purpose. I'm just fascinated by this machine.
