We are installing a induction cooktop in the island with a popup vent behind it. Both are kitchenaid. In our current kitchen we have no venting and while the popup might not be the best solution it is sufficient for us. I would like the cooktop to be installed on top of a bank of drawers for pots and pans (realizing that the top drawer would be non functional). The blower on the vent can be reversed so the main part of it would be in dead space in the island. The installation instructions still show a 4.75 inch obstruction into the cabinet. Now I realize that the vent is placed fairly close to the cooktop, but I am assuming that 4.75'' wouldnt truly be 4.75'' once it was placed behind the cooktop. Does anyone know if it is possible to do this on top of a bank of drawers, or is there not enough space behind the drawers to accomplish this? I really would prefer to avoid pullouts for pots and pans if at all possible.

Thanks!!
