maximum performance. Minimum clearance of 1" (2.5 cm) is
required to sidewalls and 3A" (1.9 cm) to rear wall.
NOTES: After making the countertop cutout, some installations
may require notching down the base cabinet side walls to clear
the cooktop base. To avoid this modification, use a base cabinet
with sidewalls wider than the cutout.
Where possible, a 6" (15.2 cm) clearance is recommended for
motor blower service. A minimum clearance of 1" (2.5 cm) is
recommended to the sidewalls and a 3/4"(1.9 cm) clearance is
recommended to the rear wall.
A minimum clearance of 2" (5.1 cm) is recommended
between the motor/blower and cabinet for proper cooling.
A minimum clearance of 61/4 '' (15.9 cm) is recommended for
removal of the grease container(s). Installed dimension for the
grease containers is 51/2"(14.0 cm).
For grills installed near a sidewall, a minimum clearance of
6" (15.2 cm) is recommended between the cooktop and
sidewall for maximum performance.

K. Wall exhaust option
Do not terminate the vent system in an attic or other enclosed
area.
• Use a Jenn-AiP vent cap.
• Vent system must terminate to the outside.
• Use only a 6" (15.2 cm) round metal vent. Rigid metal vent is
recommended. For best performance, do not use plastic or
metal foil vent.
Before making cutouts, make sure there is proper clearance
within the wall or floor for the exhaust vent.
Do not cut a joist or stud unless absolutely necessary. If a
joist or stud must be cut, then a supporting frame must be
constructed.
The size of the vent should be uniform.
The vent system must have a damper. If roof or wall cap has a
damper, do not use damper supplied with the range hood.
