Installation Instructions
Range Hood
1
WARNING:
TO REDUCE THE RISK 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 Flambe’).
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 IN THE EVENT OF
A RANGE TOP GREASE FIRE,
OBSERVE THE FOLLOWING:
a) SMOTHER FLAMES with a
close-fitting lid, cookie sheet,
or metal tray, then turn off
the burner. BE CAREFUL
TO PREVENT BURNS. If
the flames do not go out
immediately, EVACUATE
AND CALL THE FIRE
DEPARTMENT.
b) NEVER PICK UP A FLAMING
PAN - You may be burned.
c) DO NOT USE WATER,
including wet dishcloths
or towels - a violent steam
explosion will 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 called.
4) You can fight the fire with
your back to an exit.
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 servicing or cleaning
unit, switch power off at
service panel and lock
the service disconnecting
means to prevent power
from being switched on
accidentally. When the service
disconnecting means cannot
be locked, securely fasten a
prominent warning device,
such as a tag, to the service
panel.
CAUTION:
For General Ventilating Use Only.
Do Not Use To Exhaust Hazardous
Or Explosive Materials And
Vapors.

General Instructions
Carefully read the following important
information regarding installation safety and
maintenance. Keep this information booklet
accessible for further consultations.
The appliance has been designed for use in the
ducting version (air exhaust to the outside).
Installation Instructions
WARNINGS:
TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE
FOLLOWING:
1. Installation work and
electrical wiring must be
done by qualified person(s)
in accordance with all
applicable codes and
standards, including fire-rated
construction.
2. Sufficient air is needed
for proper combustion
and exhausting of gases
through the flue (chimney)
of fuel burning equipment
to prevent back drafting.
Follow the heating equipment
manufacturer’s guideline
and safety standards such
as those published by the
National Fire Protection
Association (NFPA), and
the American Society for
Heating, Refrigeration and
Air Conditioning Engineers
(ASHRAE), and the local code
authorities.
3. When cutting or drilling into
wall or ceiling, do not damage
electrical wiring and other
hidden utilities.
4. Ducted fans must always be
vented to the outdoors.
5. This unit must be grounded.
WARNING:
TO REDUCE THE RISK OF FIRE,
USE ONLY METAL DUCTWORK.
WARNINGS:
UNDER CERTAIN
CIRCUMSTANCES DOMESTIC
APPLIANCES MAY BE
DANGEROUS.
1. Do not check filters with hood
working.
2. Do not touch the lamps
after a prolonged use of the
appliance.
3. No food must be cooked
flambè underneath the hood.
4. The use of an unprotected
flame is dangerous for the
filters and could cause fires.
5. Watch constantly the fried
food in order to avoid the
cooking oil flares up.
6. Before performing any
mainteinance operation,
disconnect the hood from the
electrical service.
NOTE:
The manufacturers will not accept
any responsibility for eventual
damages, because of failure to
observe the above instructions.
NOTES:
1. Minimum hood clearances are
zero inches (0”) to the rear,
sides and top of the hood.
2. 26” (660mm) Min. distance
from electric cooktop surface
to bottom of hood.
3. 30” (762mm) Min. distance
from gas cooktop surface to
bottom of hood.

Cabinetry Planning
WARNING:
Failure to provide proper
minimum clearance may result in
a fire or safety hazard.
WARNINGS:
1. CAUTION: To reduce the
risk of fire and to properly
exhaust air, be sure to duct air
outside. Do not vent exhaust
air into spaces within walls or
ceilings, or into attics, crawl
spaces or garages.
2. Tape all duct joints securely
to prevent combustion by-
products, smoke or odors
from entering the home. This
will also improve the efficiency
of the system.
3. Do not exhaust more than one
vent into a single duct run.
4. Only use ductwork
constructed of materials
deemed acceptable by state,
municipal and local codes.
Duct Planning
NOTES:
1. Best performance is achieved
by using round duct instead of
rectangular, especially when
elbows are required.
2. If multiple elbows are
needed, ensure that there is
a minimum of 24” of straight
duct between any two elbows.
3. Avoid “S” or “back to back”
configurations caused by
adjacent elbows.
4. Thermal breaks, such as a
short section of non-metallic
duct, should be used in areas
of extreme cold.
5. A back-draft damper at the
duct outlet may also be
required.
6. Do not use flexible metal duct.
7. Do not use ductwork that is
smaller in cross-sectional area
than the recommended size
duct.
8. Do not rely on duct tape alone
to seal duct joints. Use sheet
metal screws as require to
support the duct weight.
9. The vent hood and cooking
appliance(s) must be
removable if service is
required.
10. Be certain that the ductwork
does not interfere with floor
joists or wall studs.
11. It is important to keep as few
turns in the duct run, and
to keep the run as short as
possible.
