ISLAND HOOD DUCT WORK INSTALLATION
1. Cut a 10” diameter opening in
the ceiling to accommodate the
duct work necessary for proper
ventilation.
2. Transfer the overall dimensions
of the hood top plate onto the
finished ceiling/unfinished
surface. The top plate width
and overall width will vary
with the size of the hood.
3. Construct the frame using
unistrut or wood 2x4’s. Due to
the weight of the hood,
structural support is necessary.
(See Figure 3)
4. Locate and mark the center of
the hood. Attach two wood
2x4’s across the top of the
ceiling joists. (See Figure 3)
5. Drill four 3/8” holes in the
2x4’s to match the pattern on
the top of the hood. (See
Figure 3)
6. Remove hood baffle filters
prior to installation of hood.
(See Figure 12)
WARNING: Framing must be
structurally tied together and
attached to the ceiling joists to
provide enough strength to
support the weight of the hood
and the internal blower, if
applicable.
WARNING: Island hoods are
very heavy. A minimum of three
installers are required to lift the
hood to the ceiling.
WARNING: When making any
electrical connections, make sure
electrical power is turned off at
the power source (or circuit
breaker) before proceeding.
7. Connect 10” round duct-work to
the hood transition using sheet
metal screws and/or duct tape.
8. Complete all electrical
connections. (See Wiring
Diagram, pg 22)
9. Align hood and tighten all nuts
until hood surface is flush with
ceiling. Install #10 x 2” screws
through remaining hood
mounting holes near top edge of
hood surface. This additional
support is necessary.
10. If installing an in-hood or in-line
fan, DO NOT re-install baffle
filters until blower installation is
complete. (See in-hood fan
installation instructions)
