• The cross framing must be level in all directions.
Check with a spirit level and adjust if necessary.
IMPORTANT:
The ceiling structure must be capable of supporting
the weight of the hood (approximately 100 pounds) and any
inadvertent user contact loads. It is recommended that the hood
support frame be supported by a minimum of 2 x 4 cross framing.
Finish the Ceiling
Once the ceiling is finished, mark the location of the
ceiling joist and cross framing.
• Check to be sure that ceiling is level, use shims if
necessary.
• Arrange cross framing in the ceiling to suit the
existing structure. See examples.
– Secure each 2 x 4 block with at least four (4), #10
wood screws, 3″ long (minimum size screws, not
supplied). Use 8 wood screws total for the two
supports.
• The cross framing must be accurately aligned to
assure correct positioning of the hood.

MOUNT TEMPLATE
• Align the template with the marks on the ceiling
and tape in place.
– Be sure the template is oriented correctly, with the
front of the hood.
• Use a plumb to be sure the mounting holes will
provide parallel alignment with the countertop
below.
• Center punch all hole
locations.
• Drill pilot holes in the 4 screw
locations. Use a 5/32″ bit and
drill approximately 1-1/2″
deep.
• Cut wire access hole
approximately 1″ dia.
