SAFETY INFORMATION

**** TO REDUCE THE RISK OF A FIRE, ELECTRICAL SHOCK, AND/OR INJURY OBSERVE THE FOLLOWING:

• Unit is intended for indoor residential use only. If you should have questions, contact the manufacturer at the address or telephone number listed in the warranty.

• In case the unit should need to be cleaned or repaired, 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.

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

• Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel-burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

• Because the unit is made of stainless steel, it may contain sharp edges. Be careful to avoid cuts and abrasions by wearing protective gloves during installation and cleaning.

• Before you begin to cut or drill into the wall, verify that there is no electrical
  wiring or any other hidden electrical components.

• Ducted fans must always be vented to the outdoors.

• The unit must be properly grounded and installed at the recommended height before beginning operation.

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

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.
**** TO REDUCE THE RISK OF FIRE, OR ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE.

• Regardless of heat level, never leave any surface materials unattended while operating an open flame.
• Always turn the hood ON when cooking at high heat or when flambéing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
• Depending on the amount of usage, clean ventilating fans and filters frequently. Grease should not be allowed to accumulate on the fan or filter. For instructions on how to clean, see the maintenance page.
• Never leave surface units unattended at high settings. Boil-overs may cause smoking and greasy spillovers may ignite as result. Heat oils slowly in low or medium settings.
• 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:

• 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 911.
• NEVER PICK UP A FLAMING PAN — Doing so may result in serious burns and possibly spread the fire.
• DO NOT USE WATER – Grease fire must be extinguished before further action may be taken. Using water will agitate the grease and may cause a violent steam explosion.
• Use a Fire 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 are able to safely control the fire with your back to an open exit. * Based on “Kitchen Fire safety Tips” published by NFPA.

**** PROP. 65 WARNING FOR CALIFORNIA RESIDENTS:

• This product may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
