Installation with gas cooktops

Dimension "BT" is thickness of
the backsplash. Provide 1/2"
(13 mm) clearance between the
vent cutout 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.
