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
ADAPTER/DAMPER
HOOD
range and of 30” from a gas range.
