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 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 metal ductwork.
9. This unit must be grounded.
10. When installing, servicing or cleaning the unit, it is recommended to 
wear safety glasses and gloves.
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 expenses.
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.: 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 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.
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". 
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 on a ducted 
installation, be sure to duct air outside — Do not exhaust air into 
spaces within walls or ceiling or into attics, crawl spaces or garage.
8. Because of the high exhausting capacity of this hood, 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 WPP1 series 
models should only be installed with their own built-in blowers.
10. As an alternative, this product may be installed with the UL-approved 
range hood cord kit HCK44, following instructions packed with the 
cord kit.
11. Please read specification label on product for further information and 
requirements.
