DETERMINE HOOD, DUCTWORK AND WIRING LOCATIONS
• Measure desired distance from the bottom of the
hood to the cooking surface, 24” min. to 36” max.
Refer to the previous page if the accessory duct cover
will be used.
• Use a level to draw a horizontal line indicating the
bottom of the hood.
• Use a level to draw the cooktop centerline location.
• Measure 15-3/8” up from the horizontal line for the
bottom of the hood. Draw another horizontal line.
• Measure 18” up from the line for the bottom of the
hood, draw another horizontal line to indicate the top
of the hood.
FOR VERTICAL (Straight Up) DUCTING:
• If venting out the ceiling, extend the centerline
forward on the ceiling.
– Measure 6-7/8” from drywall to mark centerline for a
7½” dia. duct hole on the ceiling.
– If drywall is not present, add drywall thickness to the
6-7/8” dimension.
Venting through a soffit or upper cabinet.
• Follow the same procedure for ceiling ducting to cut
the 7½” dia. hole through the top of the cabinet or
soffit.
• See Step 4, page 5 for details to cut opening for duct
transition.

FOR DUCTING THROUGH REAR WALL:
• Measure the supplied duct transition with any straight
run length of duct used, plus 90° elbow height. Draw a
horizontal line on the wall intersecting the centerline.

House Wiring Location:
• The junction box is fastened to the back of the hood
on the right side. See illustrations for hood knockout
locations.
Note: The junction box can be relocated to the inside
top of the hood.
House wiring may enter the junction box from the rear
or the top of the hood at the right side.
To route house wiring through the ceiling or soffit;
– Cut a hole approximately 1” dia., 5-7/8” forward on
the ceiling, 11-1/8” to the right of the centerline for
30” models or, 14-1/8” to the right of the centerline
for 36” models.
To route house wiring through the wall,
– Cut a hole approximately 1” dia., 10-1/16” down from
the top of the hood, 11-1/8” to the right of the
centerline for 30” models or, 14-1/8” to the right of
the centerline for 36” models.
• Remove top or rear knockout depending on your
installation.
