Step
Ductwork
• Use the shortest and straightest duct route
possible. For satisfactory performance, duct
run should not exceed 100 feet equivalent
length for any duct configuration.
• Refer to “Duct Fittings” chart to compute the
maximum permissible length for duct runs
to the outdoors.
• This vent hood must use 6” round duct. The
6” round duct can transition to 3-1/4” x 10”
or 3-1/4” x 12”.
• Install the house ductwork to run horizon-
tally between ceiling joists or straight up
through the roof.
Finish the Ceiling
Finish the ceiling surface. Be sure to mark
location of the ceiling joists 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.
• The cross framing must be level in all direc-
tions. 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.

a 5/32” bit and drill approximately 1-1/2”
deep.
• Cut the 6-1/4" dia. duct opening and
approx. 1" dia. wire access hole.
Install upper support frame
• Secure the upper support frame to the
ceiling joists and/or cross framing with
the 4 screws provided. For maximum
rigidity and strength, the screws must be
driven into the center of the joists and/or
cross framing.
• Check to be sure the support frame is
level, vertically and horizontally.
Install lower support frame
• Insert lower support frame (from required
accessory ZX858, ZX859 or ZX8510) into the
upper support frame and loosely secure with
8 screws and washers (4 on front and 4 on
back sides).
• Adjust the lower support frame up or down
to the desired height above the countertop.
Tighten screws.
