WARNING

TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel and lock service panel 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.

3. Installation work and electrical wiring must be done by a qualified person(s) 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), and 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 separate 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

hat 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 ventil D. Use proper pan size. Always use cookware appropriate for the size of the surface element.

ating fans frequently. Grease should not be allowed to accumulate on fan or filter.

WARNING

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE 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 off the burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.

2. NEVER PICK UP A FLAMING PAN - You may be burned.

3. DO NOT USE WATER, including wet dishcloths or towels - violent steam explosion will result.

4. Use an extinguisher ONLY if:

A. You know you have a Class ABC extinguisher and you already know how to operate

it. B. The fire is small and contained in the area where it started. C. The fire department is being called. D. You can fight the fire with your back to an exit. * Based on “Kitchen Fire Safety Tips” published by NFPA.

CAUTION

1. For indoor use only.

2. To reduce 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.

3. Take care when using cleaning agents or detergents.

4. Avoid using food products that produce flames under the Range Hood.

5. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

6. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

7. Your hood motor has a thermal overload which will automatically shut off the motor if it becomes overheated. The motor will restart when it cools down. If the motor continues to shut off and restart, have the hood serviced.

8. For best capture of cooking impurities, the bottom of the hood should be a minimum of 24" and a maximum of 30" above the cooking surface. See page 9 for mounting restrictions.

9. Two installers are recommended because of the large size and weight of this hood.

10. This product is equipped with a thermostat which may start blower automatically. To reduce the risk of injury and to prevent power from being switched on accidentally, switch power off at service panel and lock or tag service panel.

11. Use with approved cord-connection kit only.

12. Please read specification label on product for further information and requirements.

MAINTENANCE

Proper maintenance of the Range Hood will assure proper performance of the unit.

Grease Filter

Grease filter should be cleaned when the light switch flashes or remains lit when the blower is off (i.e. 30 hours of operation). Use a warm detergent solution to clean filters. Filters are dishwasher safe. See page 12 for filter removal and installation instructions.

Hood Cleaning

Stainless steel is one of the easiest materials to keep clean. Occasional care will help preserve its fine appearance.

Cleaning tips:

Hot water with soap or detergent is all that is usually needed.

•

Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth to

•

avoid water marks. For discolorations or deposits that persist, use a non-scratching household

•

cleanser or stainless steel polishing powder with a little water and a soft cloth. For stubborn cases, use a plastic scouring pad or soft bristle brush together with

•

cleanser and water. Rub lightly in direction of polishing lines or "grain" of the stainless finish. Avoid using too much pressure which may mark the surface.

DO NOT allow deposits to remain for long periods of time.

•

DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere

•

to the surface causing rust. DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds to

•

remain in contact with stainless steel for extended periods. Many of these compounds contain chemicals which may be harmful. Rinse with water after exposure and wipe dry with a clean cloth.

Painted surfaces should be cleaned with warm water and mild detergent only.

EXTERIOR BLOWER SELECTION

CAUTION: To reduce the risk of fire and electric shock, install this rangehood only with EB6, EB9, EB12 or EB15 Exterior Blowers. The exterior ventilator must be UL listed for Canadian and U.S. use, and evaluated for use with solid state speed control, rated 120V, 60 Hz, 6.0 A max.

INSTALL THE DUCTWORK

NOTE: To reduce the risk of fire, use only metal ductwork.

1. Choose the location where the exterior blower will be mounted. See illustra-

tions below for mounting location suggestions and restrictions.

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 long duct runs.

4. After the exterior blower has been installed, connect round metal ductwork and

work back towards the hood location. Use duct tape to seal joints between ductwork sections.

5. An 8” round to 10” round transition (Model 414) is required. For best air

performance, install the adapter as close to the range hood as possible.
