DESC: Ultimate styling complements virtually every cooktop style. It mounts behind most built-in cooktops in island, peninsula and wall mount installations. The unit mounts flush with the cooktop when not in operation, and is activated by light pressure on the cover which automatically raises a motor driven air intake chimney 7" above the cooktop. The elevated chimney enables smoke and vapor to be captured at the top of most cooking vessels. A touch on the top of the chimney retracts it to its down position.
