Flat Surface Area
* Includes 1/8" required gap
between cooktop and vent trim.
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.

Ducting information
The downdraft cooktop ventilation is
ideal for island or peninsula installations.
The downdraft vent retracts when
not in use.
• Vents smoke and vapors
• Quiet, powerful 500-CFM performance
Note: Approved for use with all GE
electric and sealed burner gas cooktops,
not approved for standard burner
gas cooktops.
Installation information: Before installing, consult installation
instructions packed with product for current dimensional data.
Should not exceed 150 equivalent ft.
* Equivalent lengths of duct pieces are based on actual tests conducted by GE Evaluation Engineering and reflect
requirements for good venting performance with any downdraft cooktop, with a downdraft rated at 500-CFM.
