IMPORTANT SAFETY INSTRUCTIONS

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

• Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.

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

• Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.

• Do not operate any fan with a damaged cord or plug. Discard fan or return to an authorized service facility for examination and/or repair.

• Ducted fans must always be vented to the outdoors.
  CAUTION: For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
  CAUTION: To reduce the 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.

• 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 guideline 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.

• When cutting or drilling into the wall or ceiling; do not damage electrical wiring and other hidden utilities.
  WARNING: TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

• 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.

• Always turn the hood ON when cooking at high heat or when flambéing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).

• Clean ventilating fans frequently. Grease should not be allowed to accumulate on the fan or filter.

• Use proper pan sizes. Always use cookware appropriate for the size of the surface element.
  WARNING: TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:*

• 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.

• NEVER PICK UP A FLAMING PAN – you may be burned.

• DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result

• Use an extinguisher ONLY if:
  – You know you have a class  ABC extinguisher, and you already know how to operate it.
  – The fire is small and contained in the area where it started.
  – The fire department is being called.
  – You can fight the fire with your back to an exit.

• Based on “Kitchen Fire Safety Tips” published by NFPA.

Cabinet Clearances

Given dimensions are minimum clearances.
Insert Range Hood

IMPORTANT:

• 25.6″ (65.0 cm) minimum and 29.5″ (75.0 cm) suggested maximum clearances between cooking surface and bottom of the range hood or the cabinet.
• For ducted wall venting installations using a 90° elbow, 12″ (30.5 cm) minimum overhead cabinet clearance below the wall venting opening is required.

Venting Requirements

(Ducted installations only)

• Duct system must terminate to the outdoors, except for ductless (recirculating) installations.
• Do not terminate the duct system in an attic or other enclosed area.
• Do not use 4″ (10.2 cm) laundry-type wall cap.
• Use metal duct only. A rigid metal duct is recommended. Plastic or metal foil duct is not recommended.
• The length of duct system and number of elbows should be kept to a minimum to provide efficient performance.

For the most efficient and quiet operation:

• Use rigid metal duct.
• Use no more than three 90° elbows.
• Make sure there is a minimum of 24″ (61.0 cm) of straight duct between the elbows if more than 1 elbow is used.
