prominent warning device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by qualified personnel
in accordance with all applicable codes and standards, including fire-rated
construction codes and standards.
4. 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 manufacturer’s guidelines and safety
standards such as those published by the National Fire Protection
Association (NFPA), the American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE) and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and
other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Do not use this unit with any other solid-state speed control device.
8. To reduce the risk of fire, use only steel ductwork.
9. This unit must be grounded.
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 cooking flaming foods
(i.e. Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate
on fan or filters.
d) Use proper pan size. Always use cookware appropriate for the size of the
surface element.
TO REDUCETHE RISK OF INJURYTO PERSON(S) INTHE EVENT OF A RANGE
TOP GREASE FIRE, OBSERVE THE FOLLOWING*:
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn

5. Your hood motor has a thermal overload which will automatically shut off the
motor if it becomes overheated. The motor will restart when it will cool down. If
the motor continues to shut off and restart, have the hood serviced.
6. The bottom of the hood MUST NOT BE LESS than 24” and at a maximum of
30” above cooktop for best capture of cooking impurities.
7. Two installers are recommended because of the size of this hood.
8. To reduce risk of fire and to properly exhaust air, be sure to duct air outside. Do
not exhaust air into spaces within walls or ceilings or into attics, crawl spaces,
or garages.
9. Be careful when installing the decorative flue and hood, they may have sharp
edges.

excessive or unusual noise, replace the motor with the exact service motor.The impeller
should also be replaced.
Grease Filter
The grease filter should be cleaned frequently. Use a warm detergent solution. Grease
filter is dishwasher safe.
Clean all-metal filters in the dishwasher using a non-phosphate detergent.Discoloration of
the filter may occur if using phosphate detergents, or as a result of local water conditions -
but this will not affect filter performance.This discoloration is not covered by the warranty.
See “INSTALL FILTERS” section for removal and installation instructions.
Non-ducted Recirculation Filter
The non-ducted recirculation filter should be changed every 6 months. Replace more
often if your cooking style generates extra grease, such as frying and wok cooking. See
“INSTALL FILTERS” section for removal and installation instructions.
Stainless Steel Cleaning
DO:
• Regularly wash with clean cloth or rag
soaked with warm water and mild soap
or liquid dish detergent.
• Always clean in the direction of original
polish lines.
• Always rinse well with clear water (2 or
3 times) after cleaning. Wipe dry com-
pletely.
• You may also use a specialized house-
hold stainless steel cleaner.
DON’T:
• Use any steel or stainless steel wool or
any other scrapers to remove stubborn
dirt.
• Use any harsh or abrasive cleansers.
• Allow dirt to accumulate.
• Let plaster dust or any other construc-
tion residues reach the hood. During
construction/renovation, cover the range
hood to make sure no dust sticks to the
stainless steel surface.
Avoid:When choosing a detergent
• Any cleaners that contain bleach will attack stainless steel
• Any products containing:chloride, fluoride, iodide, bromide will deteriorate surfaces rapidly.
• Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc.,
are highly explosive and should never be used close to a range.

NOTE: To reduce the risk of fire, use
only metal ductwork.
1. Decide where the ductwork will run
between the hood and the outside.
2. A straight, short duct run will allow
the hood to perform most efficiently.
3. Long duct runs, elbows, and
transitions will reduce the
performance of the hood. Use as
few of them as possible. Larger
ducting may be required for best
performance with longer duct runs.
4. Install a roof or wall cap. Connect
round metal ductwork to cap and work back towards hood location. Use duct
tape to seal the joints between ductwork sections.
1. GROUNDING INSTRUCTIONS
This appliance must be grounded.
In the event of an electrical short
circuit, grounding reduces the risk
of electric shock by providing an
escape wire for the electric current.
This appliance is equipped with a
cord having a grounding wire with
a grounding plug. The plug must
be plugged into an outlet that is
properly installed and grounded.
2. Position the electrical outlet
within the space covered by the
decorative flue and where it will not
interfere with the round duct. Make
sure the outlet is no further than
11½” from where the cord exits from the hood and that the outlet does not
interfere with a mounting bracket fastening area or where the decorative flue
touches the wall.

POUR RÉDUIRE LES RISQUES D’INCENDIE CAUSÉS PAR DE LA GRAISSE SUR LE
PLAN DE CUISSON :
a) Ne laissez jamais les éléments de surface allumés à haute température. Les débordements
peuvent causer de la fumée et occasionner des écoulements de graisse inflammables.
L’huile doit être chauffée graduellement à basse ou à moyenne température.
b) Mettez toujours la hotte en MARCHE lors de la cuisson à feu vif ou lors de la cuisson
d’aliments à flamber ( crêpes Suzette, cerises jubilé, bœuf au poivre flambé).
c) Nettoyez souvent la hotte.Ne laissez pas la graisse s’accumuler sur le ventilateur ou les filtres.
d) Utilisez des casseroles de dimension appropriée. Utilisez toujours une batterie de cuisine
adaptée à la dimension de la surface chauffante.
