INSTALLATION
Take measurements
1. Refer to the cooktop installation instructions for
dimensions of cooktop, countertop cut-out, and
cabinet requirements. However, it is recommended
that oversized cabinets be used for easier installation.
Custom island designs need to account for deeper
cabinets, especially when mounting the blower behind
the downdraft. You must also plan for an access door.
Pay special attention to the areas of potential interference
highlighted below. A countertop with (A) a raised lip and/or
(B) a backsplash may not allow enough ß at countertop for a
proper installation. Note that a minimum of 2-7/8" (73 mm)
of ß at countertop is required behind cooktop (C) and that a
minimum of 2-7/8" (73 mm) is necessary between the back
edge of the cooktop and the inside of cabinet back (D).

Installation with electric and induction cooktops
Dimension "BT" is thickness of
the backsplash that provides
1/2" (13 mm) clearance
between the vent and the
backsplash. Any backsplash
with a curved radius where it
meets the counter will require
additional clearance. Thicker
backsplashes may be used
by increasing the counter and
cabinet depths.
Set the cooktop into the
coutertop opening so that
the back edge of the cooktop
overlaps the leading edge of
the downdraft.
