IMPORTANT SAFETY INSTRUCTIONS
WARNING
To reduce the risk of FIRE,
ELECTRIC SHOCK OR INJURY to persons, observe
the following:
A. Use this unit only in the manner
intended by the manufacturer. If
you have questions, contact the
manufacturer.
B. Before installing, servicing or clean-
ing the unit, switch power off at
service panel and lock service panel
to prevent power from being
switched on accidentally.
C Installation work and electrical wir-
ing must be done by qualified
person(s) in accordance with all
applicable codes & standards, including fire-rated construction.
D. Sufficient air is needed for proper
combustion and exhausting of gases
through the flue (chimney) of fuel
burning equipment to prevent
backdrafting. Follow the heating
equipment manufacturers guideline and safety standards such as
those published by the National
Fire Protection Association (NFPA),
and the American Society for Heat-
ing, Refrigeration and Air Conditioning Engineers (ASHRAE), and
the local code authorities.
E. Due to size and weight of this unit,
two installers are recommended.
F. When cutting or drilling into wall
or ceiling, do not damage electrical
wiring and other hidden utilities.
G. Ducted fans must always be vented
to the outdoors and upward. D o
not vent to the attic or crawl space.
H. To reduce the risk of fire, use only
metal duct work.
I. Install this hood in accordance
with all requirements specified
by the manufacturer of your
cooktop/range.
J. Flex duct is not recommended.
To reduce the risk of a
RANGE TOP GREASE
FIRE.
a) Never leave surface units unat-
tended at high settings. Boilovers cause smoking and greasy
spillovers that may ignite. Heat
oils slowly on low or medium
settings.
WARNING
b) Always turn the hood ON
when cooking at high heat or
when flambéing foods.
c) Clean ventilating fans fre-
quently. Grease should not
be allowed to accumulate on
fan or filter.
d) Use proper pan size. Always
use cookware appropriate for
the size of the surface element.
CAUTION
:
FOR VENTILATION USE
ONLY. Do not use to exhaust hazardous or explosive materials or vapor.
CAUTION:
Vent unit to the outside.

TYPICAL INSTALLATION
The Professional Island hood is designed to be installed on a rigid structural framing. Follow these
installation steps for proper hood performance. Typical installation of the Island Hood is shown in Figure 1.
10" Transition
To Be Connected to
Remote Ventilator
12" min.
NOTE: BECAUSE OF THE SIZE AND
WEIGHT OF THE ISLAND HOOD, IT IS
NECESSARY TO MAKE A 12" WIDE BY
HOOD LENGTH SOFFIT WITH RIGID
STRUCTURAL FRAMING IN AN 8-FOOT
HIGH KITCHEN CEILING.
Adjustable chimney structures are available.
STEP 1 SOFFIT FRAMING
a) Locate and mark the center line of the hood location.
b) Use 2 pieces of 2" x 6" x 6 feet wood spacers and
bolt these pieces onto the ceiling joist as shown in
Fig. 2.

30" to

Vertical Studs
Spacer
If the ceiling joists are spaced more than 16" apart
center to center, it is necessary to install additional
spacers so that when installing the vertical studs,
they will be 11" apart. See Fig. 3.
c) Using 1/4" diameter x 5" long lug screws, attach 2"
x 6" vertical studs onto the spacers so that their
inner edges are 23" apart. See Fig. 2
The length of these studs depends on the ceiling
height and the desired height of the hood from the
top of the cooktop. The bottom of the hood is
recommended to be within 30" to 36" over the range
cooking surface.
48" Hood - 46 3/4"
60" Hood - 58 3/4"

d) Construct the bottom wood framing with 2" x 4"s as
shown in Fig. 4. The center of the frame must have
an opening of 10" x 23" for the transition duct.
e) The overall length of the structural framing will
depend on the size of the island hood. Attach 2"
x 4" wood frame onto the ends of 2" x 6" so that
their outer edges are 47" apart for 48" hood, or 59"
apart for a 60" hood. See Figure 2.
NOTE: Because of the weight of the
hood, we are recommending that you
use metal joint straps to connect the
ends of wood framing per example of
Figure 4.
See Detail "A"
2" x 4" Frame
f) Using 2" x 6" wood, construct the bottom framing
for duct opening at the center bottom of the soffit. The
duct opening must be 8" x 23" as shown in Fig. 7.
STEP 2
INSTALL HOOD ASSEMBLY
a) Install the transition (provided) to the top of the
hood using #8 x 1/2" Philips head screws. Tape all
joints, with duct tape.
b) Locate and mark the centerlines of the hood soffit
framing and hood assembly. Align both center
lines and secure the hood assembly with 8 pieces
- 1/4" diameter x 1-1/2" long lug bolts with taps
and 2" x 2" x 1 1/2" angle brackets.
STEP 3
DUCTING INSTALLATION
a) Run 10" round duct work from the remote ventilator
Model #VTR1000Q or Model #VTR1400Q (purchase separately) to the transition (provided with
the hood). See Figure 1.
b) Seal all joints with duct tape. Use straight duct if
possible or, if necessary, the fewest elbows for
best performance.

NOTE: COLD WEATHER installations
should have an additional backdraft damper
installed to minimize backward cold air flow.
A nonmetallic thermal break can be installed
to minimize conduction of outside temperature as part of the ductwork. The damper
should be on the cold air side of the thermal
break. The break should be as close as
possible to where the ducting enters the
heated portion of the house.

entrance and lock out panel before
wiring this unit.
I WIRING TO THE REMOTE VENTILA-
TOR:
a) Run five wires #12 AWG MIN. (black white, blue, red,
and green) in 1/2" conduit from the remote ventilator
to the J-Box located in the hood assembly. See Fig,
6.
b) Strip approximately 3/8" at the end of the above
wires. Use spring type wire nuts supplied to connect
blue, red, black, white and green wires to corresponding color wires located inside the J-box. (Note:
Follow the wiring diagram supplied with ventilator.)
(Lost or missing wire nuts should only be replaced
with: Spring type wire nuts, rated for a minimum of
(2) # 18ga wires and maximum of (4) #14ga wires,
UL & CSA rated to 600V and 302 deg. F./150 deg. C).
See Care and Use Manual for instructions.

II WIRING TO THE POWER SUPPLY:
a) Power supply required for this model is 120V., 19
Amps., 60 Hz. Using flex conduit , run three (3) #12
AWG. maximum (black, white, and green) from the
service panel to the J-Box located in the hood. See
Fig. 6.
b)
Strip approximately 3/8" at the end of these three
wires. Use the provided wire nuts to connect the
black, white, and green wires to the corresponding
color wires located inside the J-box. (Note: follow
the wiring diagram.)
c) When using the power supply in a damp location or
outdoors, always install it in a GFCI protected branch
circuit.
