36" and 30" cooktop/downdraft system counter installation
JVB98SH/94SH, JVB67H/37H
Note: The countertop must be at least 26" deep with a flat surface area
of 23-1/2" or more, front to back. In addition, other clearances to the
front edge must be considered.
Note: JP950S, JP940S, JP930S, JP910S, JGP940S require 23-5/8" flat
surface area.
Note: See specific cutout illustrations with your cooktop model to
determine requirements.
Note: A countertop with a raised or a rolled front edge may not allow
enough flat area for installation.

It is recommended that gas and/or electrical
service for cooktop and downdraft should not be
placed on the back wall because it may interfere
with the downdraft plenum.
