WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC 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 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.

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) 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 outdoors.

7. Do not use this unit with any solid-state speed control device.

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

9. This unit must be grounded.

10. All tempered glass can experience spontaneous breakage. If

broken, tempered glass falls out of its opening in interlocking
clumps. Tempered glass can, on occasion, break into large
shards rather than the classic tiny piece pattern.

11. When applicable, local regulations comprise more

restrictive installation and/or certification requirements,
the aforementioned requirements prevail on those of this
document and the installer agrees to conform to these at his
own expense.

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 power hood ON when cooking at high heat or

when flambeing food (i.e.: Crêpes Suzette, Cherries Jubilee,
Peppercorn Beef Flambé).

c) Clean ventilating fans frequently. Grease should not be allowed

to accumulate on fan, filters or in exhaust ducts.

d) Use proper pan size. Always use cookware appropriate for the

size of the surface element.

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 —

This could cause a violent steam explosion.

4. Use an extinguisher ONLY if:
A. You own a Class ABC extinguisher and you know how to

operate it.

B. The fire is small and contained in the area where it started.
C. The fire department has been 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. For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

3. To avoid motor bearing damage and noisy and/or unbalanced

impellers, keep drywall spray, construction dust, etc. off power
unit.

4. Your hood motor has a thermal overload which will automatically

shut off the motor if it overheats. The motor will restart when it
cools down. If the motor continues to shut off and restart, have
the hood serviced.

5. The minimum hood distance above cooktop must not be

less than 24” (30” over a gas range). A maximum of 30”
above cooktop is recommended for best capture of cooking
impurities.

6. Two installers are recommended because of the large size and

weight of this unit.

7. To reduce the risk of fire and to properly exhaust air, be sure to

duct air outside — Do not exhaust air into spaces within walls
or ceiling or into attics, crawl space or garage.

8. Because of the high exhausting capacity of this hood, you

should make sure enough air is entering the house. Open a
window close to or in the kitchen.

9. To reduce the risk of fire and electrical shock, the Best WCB3I

Series models should only be installed with its own built-in
blower.

10. Please read specification label on product for further

information and requirements.

1. INSTALL DUCTWORK

Plan where and how the ductwork will be installed.
The ducting from this fan to the outside of the building has a strong effect on the airflow,

noise and energy use of the fan. Use the shortest, straightest duct routing possible for
best performance, and avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated airflow. Refer to the table below to help you
plan the most efficient installation.

DECORATIVE

Install wall or roof cap and ensure there is no leak in house insulation. Connect metal
ductwork to cap and work back towards the hood location. Use 2” metal foil duct tape to
seal the joints.

We recommend to install the hood at a minimum distance of 24” from an electric

prominent warning device, such as a tag, to the service panel.

HYBRID FILTERS

Hybrid filters should be cleaned monthly. Remove hybrid filters by pushing them towards the back of the hood and flipping them downward.
Use a warm detergent solution to clean the filters. Let them dry and reinstall them. Hybrid filters are dishwasher safe. Clean all-metal filters
in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergent or as a result of local
water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty.

STAINLESS STEEL

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 completely.

• You may also use a specialized household stainless steel
cleaner

GLASS PANEL

Hot water with mild soap or glass cleaner is all that is usually needed.
When using mild soap, rinse with clear water. Wipe dry with a clean, soft cloth to avoid water marks.

Avoid when choosing a detergent:

- Any cleaners that contain bleach. They will attack stainless steel.

- Any products containing: chloride, fluoride, iodide, bromide. They will deteriorate surfaces rapidly.

- Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc. They are highly explosive and should never

be used close to a range.

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 construction residues reach the
hood. During construction/renovation, cover the hood to make
sure no dust sticks to stainless steel surfaces.

12

20. OPERATION

!

Always turn your hood on before you begin cooking to establish an airflow in the kitchen. Let the blower run for a few minutes to clear the
air after you turn off the range.

CAUTION

REPLACEMENT PARTS AND REPAIRS

In order to ensure your unit remains in good working condition, you must use Broan-NuTone genuine replacement parts only. Broan-NuTone genuine
replacement parts are specially designed for each unit and are manufactured to comply with all the applicable certification standards and maintain a high

23. WARRANTY

FIVE-YEAR LIMITED WARRANTY FOR BEST® PRODUCTS

Warranty Period and Exclusions: Broan-NuTone, LLC (the “Company”) warrants to the consumer purchaser of its product (“you”) that the product (the

“Product”) will be free from material defects in the materials or its workmanship for a period of five (5) years from the date of original purchase (or such
longer period as may be required by applicable law) or a period of two (2) years from the date of service for any labor provided on the Product.
The limited warranty period for any replacement parts provided by the Company and for any Products repaired or replaced under this limited warranty shall
be the remainder of the original warranty period (or such longer period as may be required by applicable law).

THIS WARRANTY DOES NOT EXTEND TO FLUORESCENT LAMP STARTERS, TUBES AND BULBS, FUSES, FILTERS, DUCTS, ROOF CAPS, WALL CAPS
AND OTHER ACCESSORIES FOR DUCTING. This warranty does not cover (a) normal maintenance and service, (b) normal wear and tear, (c) any Products or

parts which have been subject to misuse, abuse, abnormal usage, negligence, accident, improper or insufficient maintenance, storage or repair (other than
repair by the Company), (d) damage caused by faulty installation, or installation or use contrary to recommendations or instructions, (f) damage caused by
exposure to salt air, (g) damage in transit, (h) natural wear of finish, (i) Products in commercial or nonresidential use, (j) damage caused by fire, flood or
other act of God, or (k) Products with altered, defaced or removed serial numbers. This warranty covers only Products sold to consumers in North America.
This warranty supersedes all prior warranties and, subject to applicable law, is not transferable from the original consumer purchaser.
No Other Warranties: This Limited Warranty contains the Company’s sole obligation and your sole remedy for defective Products. The foregoing warranties
are exclusive and in lieu of any other warranties and conditions, express or implied. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE

COMPANY DISCLAIMS AND EXCLUDES ALL OTHER EXPRESS WARRANTIES AND CONDITIONS, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES
AND CONDITIONS IMPLIED BY LAW, INCLUDING WITHOUT LIMITATION THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

To the extent that applicable law prohibits the exclusion of implied warranties or conditions, the duration of any applicable implied warranty or condition
is limited to the period specified for the express warranty above. Some jurisdictions (which may include the Province of Quebec or specific US states) do
not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. Any oral or written description of the Product is
for the sole purpose of identifying it and shall not be construed as an express warranty.
Whenever possible, each provision of this Limited Warranty shall be interpreted in such manner as to be effective and valid under applicable law, but if any
provision is held to be prohibited or invalid, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the other remaining provisions of the Limited Warranty.
Remedy: During the applicable limited warranty period, the Company will, at its option, provide replacement parts for, or repair or replace, without charge,
any Product or part thereof, to the extent the Company finds it to be covered by and in breach of this limited warranty under normal use and service. The
Company will ship the repaired or replaced Product or replacement parts to you at no charge. You are responsible for all costs for removal, reinstallation
and shipping, insurance or other freight charges incurred in the shipment of the Product or part to the Company. If you must send the Product or part
to the Company, as instructed by the Company, you must properly pack the Product or part—the Company is not responsible for damage in transit. The
Company reserves the right to utilize reconditioned, refurbished, repaired or remanufactured Products or parts in the warranty repair or replacement
process. Such Products and parts will be comparable in function and performance to an original Product or part and warranted for the remainder of the
original warranty period (or such longer period as may be required by applicable law).
Company reserves the right, in its sole discretion, to refund the money actually paid by you for the Product. If the Product or component is no longer
available, replacement may be made with a similar product of equal or greater value, at Company’s sole discretion. This is your sole and exclusive remedy
for breach of this limited warranty.

Exclusion of Damages: THE COMPANY’S OBLIGATION TO PROVIDE REPLACEMENT PARTS, OR REPAIR OR REPLACE, AT THE COMPANY’S OPTION,
SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY UNDER THIS LIMITED WARRANTY AND THE COMPANY’S SOLE AND EXCLUSIVE OBLIGATION. THE
COMPANY SHALL NOT BE LIABLE FOR INCIDENTAL, INDIRECT, CONSEQUENTIAL OR SPECIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH
THE PRODUCT, ITS USE OR PERFORMANCE.

Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply
to you. This warranty gives you specific legal rights, and you may also have other rights, which vary from jurisdiction to jurisdiction. The disclaimers,
exclusions, and limitations of liability under this warranty will not apply to the extent prohibited by applicable law.
This warranty covers only replacement or repair of defective Products or parts thereof at the Company’s main facility and does not include the cost of field
service travel and living expenses.
Any assistance the Company provides to or procures for you outside the terms, limitations or exclusions of this limited warranty will not constitute a waiver
of such terms, limitations or exclusions, nor will such assistance extend or revive the warranty. The Company will not reimburse you for any expenses
incurred by you in repairing or replacing any defective Product, except for those incurred with the Company’s prior written permission.
How to Obtain Warranty Service: To qualify for warranty service, you must (a) notify the Company at the address or telephone number stated below within
seven (7) days of discovering the covered defect, (b) give the model number and part identification and (c) describe the nature of any defect in the Product
or part. At the time of requesting warranty service, you must present evidence of the original purchase date. If you cannot provide a copy of the original
written limited warranty, then the terms of the Company’s most current written limited warranty for your particular product will control.
