C. nstallation Work and Electri-
cal Wiring Must Be Done By
Qualified Person(s) n Accor-
dance With All Applicable Codes
& Standards, ncluding Fire-
rated Construction.
D. Sufficient air is needed for
proper combustion and ex-
hausting of gases through the
flue (chimney) of fuel burning
equipment to prevent back-
drafting. Follow the heating
equipment manufacturers
guideline and safety standards
such as those published by the
National Fire Protection Asso-
ciation (NFPA), the American

IMPORTANT SAFETY INSTRUCTIONS
WARNING- TOREDUCETHERISK
OF A RANGE TOP GREASE FIRE.
a) Never leave surface units
unattended at high settings.
Boilovers cause smoking and
greasy spillovers that may
ignite. Heat oils slowly on low
or medium settings.
b) Always turn hood ON when
cooking at high heat or when
flambeing food (i.e. Crepes
Suzette, Cherries Jubilee,
Peppercorn Beef Flambee).
c) Clean ventilating fans
frequently. 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.
WARNING - TO REDUCE THE
RISK OF INJURY TO PERSONS,
INTHEEVENT OF ARANGETOP
GREASE FIRE, OBSERVE THE
FOLLOWING:
a) SMOTHER FLAMES with a
close-fitting lid, cookie sheet,
or other metal tray, then turn
off the gas burner or the electric
element. BE CAREFUL TO
PREVENT BURNS. f the flames
do not go out immediately,
EVACUATE AND CALL THE F RE
DEPARTMENT.
b) NEVER P CK UP A FLAM NG PAN
- you may be burned.
c) DO NOT USE WATER, including
wet dishcloths or towels - a
violent steam explosion may
result.
d) Use an extinguisher ONLY if:
1)You know you have a class
ABC extinguisher, and you
already know how to operate it.
2)The fire is small and
contained in the area where it
started.
3)The fire department is being

BEFORE INSTALLING HOOD
1. For the most efficient air flow
exhaust, use a straight run or
as few elbows as possible.
CAUTION: Vent unit to
outside of building, only.
2. Almost two people are
necessary for installation.
3. The hood is fitted with Screws
and Drywall Anchors suitable
for most surfaces, consult a
Qualified nstaller, check if
they perfectly fit with your
cabinet/wall.
4. Do not use flex ducting.
5. COLD WEATHER installations
should have an additional
backdraft damper installed to
minimize backward cold air
flow and a nonmetallic
thermal break to minimize
conduction of outside tem-
peratures 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.
6. Remote blowers require a five
wire installation.
7. Make up air: Local building
codes may require the use of
Make-Up Air Systems when
using Ducted Ventilation
Systems greater than
specified CFM of air
movement.
The specified CFM varies
from locale to locale. Consult
your HVAC professional for
specific requirements in your
area.

TYPICALINSTALLATION
The hoods are designed for either
vertical or horizontal discharge as
shown in Figure A and B
respectively.
The height from the countertop
tothebottomofthehoodis30"to
36”.These hoods are not
recommended to be used over
indoor grills.
DUCTING
Provide a Round Duct having a
diameter of 8 (see Figure A and B
for location and Figure 1 for location
on wall or cabinet bottom).
nstall a 1/2 conduit from the
service panel long enough to reach
the hood once it is installed.
Power supply must be rated for 120V
60Hz, 15 amps (minimum).
Note - Horizontal Discharge:
The Transition for this discharge
direction is not supplied and
must be purchased separately.

Discharge Direction: The hood is
shipped ready for horizontal
discharge. To change to vertical
discharge move plate to the rear
side and ventilator (if supplied) to
the top side.
The plate and ventilator are held in
place by four nuts each, see also
Figures 3 and ,at page 9, Figure A
and Figure B.
Read also paragraph  ntegral
Ventilator nstallation at pages
14-15 for further informations.
Note: f an integral ventilator is
already supplied (HSB series hoods
only), remove it to allow installation
of hood to the wall/cabinet.
Assembly of the Transition:
The transition supplied with the
hood mounts to the top of the
hood, Figure 4.
1. Fold outwards all six Tabs (HS
and HSB series only).
2.Align mounting holes at base
of transition with mounting
holes on 1/2 flange located at
the top of the hood.
3.Fasten transition to hood using
6 (4 mm x 9.5 mm) screws
(included with hood).
4.Duct tape connection between
transition and hood.
5. Remove tape holding damper

1. After the hood installation height
has been determined draw a
horizontal line at a distance
above the cooktop equal to the
desired hood installation height
plus 7- 1/2”.
2. Find the centerline of the
cooktop. Draw a vertical line
along this centerline up to
the horizontal line drawn in
step 1 and draw a vertica
line right and left at a
distance of 12-5/8” to
determine the mounting
location of the mounting
hooks shipped with the hood.
3. Fit two mounting hooks on
the wall to hang the hood
through the provided slots (2
wall anchors+2 hooks + 2
screws 5x45).
4. Run 8 Duct, long enough to
reach the transition once the
hood has been installed plus 1
1/2 inch to connect
ductwork.
Fix Duct to transition with
screws and seal with tape.
5. f mounted, remove the
grease filter.
6. Remove 1 of 2 knockouts and
install 1/2 conduit connector
in j-box.
7. Hang the hood and adjust its
position through the screws
on the hooks.
8. Fix the hood to 4 additional
point,2 on upper side, 2 on
lower side (use 4 wall anchors
+ 4 washers + 4 screws 5x35.

Wall Mount Installation -
HST series Hood only
(see Figure 6-7-8)
1. Hood nstallation Height
After the hood installation height
has been determined draw a
horizontal line at a distance
above the cooktop equal to the
desired hood installation height
plus 16 1/2. This line is the
mounting location of the wooden
bracket shipped with the hood.
2. Find the centerline of the
cooktop. Draw a vertical line
along this centerline up to the
horizontal line drawn in step 1.
3. The HST series hoods are
mounted to the wall using a
wooden bracket shipped with
the hood. Remove the bracket
from the hood by removing two
shipping screws. Mark the
centerline of the bracket.
4. Find studs behind the drywall
by tapping the wall or using a
stud finder. Locate one stud on
either side of the cooktop
centerline to use for mounting
the wooden bracket as shown
in Figure 6.
5. Align the top of the wood bracket
along the horizontal line drawn
in step 1. Align the centerlines
of the bracket and cooktop.
6. Drill a 3 deep 1/8 tap hole
through the wooden bracket,
drywall, and into the stud.
7. Use 2-4 (6mm x 80 mm) screws
to attach the bracket to the wall
as shown in Figure 7. For
support of longer hoods, use
Figure 6

three or four studs as available.
Countersink the heads to pre-
vent interference with the
hood.
8. On the wood bracket mark the
locations used to hang the hood
according to Figure 7.
9. Drill a 1/8 tap hole through
the wooden bracket and drywall.
These screws do not need to go
into the studs.
10.Screw 2 (4.2mm x 18 mm)
screws into the wood bracket
leaving 1/4 of the screw ex-
posed for hanging the hood.
11.Discharge Direction: Horizon-
tal discharge requires a wall
cutout, as shown in Figure 1 of
this manual, to provide clear-
ance for the transition. The
location of the cutout is deter-
mined by the hood installation
height.
For Vertical discharge,please
refer to step 4, Page 10.
12.Hang the hood using slots I in
Figure 8. Make sure the wood
bracket fits into the recess on
the back of the hood.
13.Tighten the screws in slots I.
Use slots I to level the hood.
14.From inside the hood drive 4 or
6 screws depending on model
(4.2 mm x 18 mm) through holes
J into wooden bracket.
15.Drill a 3/8 tap hole through
the center of the holes K into
the wall. nsert two wall plugs
into drilled holes. Tighten hood
to wall anchors by installing 2
screws with washers.

1. Find the centerline of the
cabinet bottom. Draw a line
along this centerline from rear
to front of the cabinet.
2. Draw two lines, one at a K
distance from the wall, the other
one at a Z distance from the
previous line.
Mark 4 points , two along each
line at a distance of half W from
the center line, to determine
the screw locations.
3. Fit 4 screws on cabinet bottom

leave a space of about 1/2 from
cabinet bottom surface and
head screws.
4. Run 8 Duct, long enough to
reach the transition once the
hood has been installed plus 1
1/2 inch for connect
ductwork.
Fix Duct to transition with
screws and seal with tape.
5. f mounted, remove the
grease filter.
6. Remove 1 of 2 knockouts and
install 1/2 conduit connector
in j-box.
7. Hang the hood on screws
through side slots provided on
hood top.
Tighten the four screws.
f possible fix the hood on the wall at
4 additional point (2 on upper side,
2 on lower side).
