Installation with gas 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.
