These precautions will reduce the risk of burns, electric shock, fire, and injury to persons. When using kitchen appliances, basic safety precautions must be followed, including those in the following pages.

General notes

Examine the appliance after unpacking it. In the event of transport damage, do not plug it in.

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 unit, switch power off at service panel and lock the 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.

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

• Installation work and electrical wiring must be done by qualified person(s) 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 guideline 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.
• When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
• Ducted fans must always be vented to the outdoors.

This appliance is not intended for operation with an external clock timer or a remote control.

Have an appropriate fire extinguisher available, nearby, highly visible and easily accessible near the appliance.

Fire Safety

To reduce risk of fire and to properly exhaust air, be sure to duct air outside. Do not vent exhaust air into spaces within walls, ceilings, attics, crawl spaces or garages.

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

Always have a working smoke detector near the kitchen.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

1. 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.
2. Always turn hood ON when cooking at high heat.
3. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
4. Use proper pan size. Always use cookware appropriate for the size of the surface element.

Do not flambé under the extractor hood or work with a naked flame. When switched on, the extractor hood draws flames into the filter. There is a risk of fire due to deposits on the grease filter!

For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

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

Do not run cord under carpeting. Do not cover cord with throw rugs, runners, or similar coverings. Do not route cord under furniture or appliances. Arrange cord away from traffic area and where it will not be tripped over.

In the event that personal clothing or hair catches fire, drop and roll immediately to extinguish flames.

Smother flames from food fires other than grease fires with baking soda. Never use water on cooking fires.

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.

Whenever possible, do not operate the ventilation system during a cooktop fire. However, do not reach through fire to turn it off.

RISK OF FIRE
When gas burners are in operation without any cookware placed on them, they can build up a lot of heat. A ventilation appliance installed above the cooker may become damaged or catch fire. Only operate the gas burners with cookware on them.

RISK OF FIRE
During simultaneous use of multiple gas burners, a great deal of heat is created. A ventilation device located above it can become damaged or catch fire. Never use two gas burners together at maximum heat for longer than 15 minutes. One large burner with over 17,000 BTU/hr (5 kW) (wok) is equal to the wattage of two gas burners.

RISK OF FIRE
Hot oil and fat catch fire fast. Never leave hot oil and fat unsupervised. Never extinguish a fire with water. Switch off the cooking position. Suffocate flames carefully with a lid, a fire blanket or similar.

RISK OF FIRE
Grease deposits in the grease filter can ignite.
Clean the grease filter at least every two months.
Never operate the appliance without the grease filter.

RISK OF FIRE
Grease deposits in the grease filter can catch fire. Never work with a naked flame near the appliance (e.g. flambéing). Install the unit near a heat-producing appliance for solid fuels (e.g. wood or coal) only if there is a closed, non-detachable cover. There must be no flying sparks.

Burn Prevention

RISK OF BURNS
The accessible parts get hot during operation. Never touch hot parts. Keep children away.

Be sure the entire appliance (including the grease filters and light bulbs, if applicable) has cooled and grease has solified before attempting to clean any part of the appliance.
Do not use steam cleaners to clean the appliance.

Safe use

Do not repair, replace or remove any part of the appliance unless specifically recommended in the manuals. Improper installation, service or maintenance can cause injury or property damage. Refer to this manual for guidance. All other servicing should be done by an authorized servicer.

RISK OF INJURY
Items placed on the appliance may fall down. Do not place any objects on the appliance.

Proper Installation and Maintenance

Have the installer show you the location of the circuit breaker or fuse. Mark it for easy reference. This appliance must be properly installed and grounded by a qualified technician. Connect only to properly grounded outlet. Refer to Installation Instructions for details.

This appliance is intended for normal family household use only. It is not approved for outdoor use. See the Statement of Limited Product Warranty. If you have any questions, contact the manufacturer.

Do not store or use corrosive chemicals, vapors, flammables or nonfood products in or near this appliance. It is specifically designed for use when heating or cooking food. The use of corrosive chemicals in heating or cleaning will damage the appliance and could result in injury.

Do not operate this appliance if it is not working properly, or if it has been damaged. Contact an authorized servicer.

Do not repair or replace any part of the appliance unless specifically recommended in this manual. Refer all servicing to a factory authorized service center.

Grease left on filters can remelt and move into the vent.

Turn power off at breaker before removing a damaged bulb. Do not touch the bulbs immediately after use. The bulbs will remain hot for several minutes.

Make sure the appliance and lights are cool and power to the appliance has been turned off before replacing the light bulb(s). Failure to do so could result in electrical shock or burns. The lenses (if equipped) must be in place when using the appliance. The lenses (if equipped) serve to protect the light bulb from breaking. The lenses (if equipped) are made of glass. Handle carefully to avoid breaking. Broken glass can cause an injury.

Hidden surfaces may have sharp edges. Use caution when reaching behind or under appliance.

When the hood is operated in exhaust-air mode simultaneously with a different burner which also makes use of the same chimney (such as gas, oil or coal-fired heaters, continuous-flow heaters, hot-water boilers) care must be taken to ensure that there is an adequate supply of fresh air which will be needed by the burner for combustion.

Safe operation is possible provided that the under pressure in the room where the burner is installed does not exceed 4 Pa (0.04 mbar).

This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the air-intake/exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc.

Avoid carbon monoxide poisoning – Provide adequate air intake so combustion gases are not drawn back into the room.
An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded.

Note: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as cooktops and ovens.
