Safety Practices for Servicer

Safe and satisfactory operation of gas ranges depends upon its design and proper installation. However, there is one more area of safety to be considered:

Servicing

Listed below are some general precautions and safety practices which should be followed in order to protect the service technician and consumer during service and after service has been completed.

1. Gas smell—Extinguish any and all open flames and open windows.

2. Turn gas off—Service range with gas turned off unless testing requires it.

3. Checking for gas leaks—Never check for leaks with any kind of open flame. Soap and water solution should be used for this purpose. Apply solution to suspected area and watch for air bubbles which indicates a leak. Correct leaks by tightening fittings, screws, connections, applying approved compound, or installing new parts.

4. Using lights—Use a hand flashlight when servicing ranges or checking for gas leaks. Electric switches should not be operated where leaks are suspected. This will avoid creating arcing or sparks which could ignite the gas. If electric lights are already turned on, they should not be turned off.

5. Do not smoke—Never smoke while servicing gas ranges, especially when working on piping that contains or has contained gas.

6. Check range when service is completed—After servicing, make visual checks on electrical connection, and check for gas leaks. Inform consumer of the condition of range before leaving.

7. Adhere to all local regulations and codes when performing service.

Receiving Oven

• Installer needs to show consumer location of the range

gas shut-off valve and how to shut it off.

• Authorized servicer must install the range, in

accordance with the Installation Instructions. Adjustments and service should be performed only by authorized servicer.

• Plug range into a 120–volt grounded outlet only. Do

not remove round grounding prong from the plug. If in doubt about grounding of the home electrical system, it is consumers responsibility and obligation to have an ungrounded outlet replaced with a properly grounded three-prong outlet in accordance with the National Electrical Code. Do not use an extension cord with this appliance.

• Insure all packing materials are removed from the

range before operating it, to prevent fire or smoke damage should the packing material ignite.

• Ensure range is correctly adjusted by a qualified

service technician or installer for the type of gas (Natural or LP). Some ranges can be converted for use with Natural or LP gas.

• With prolonged use of a range, high floor

temperatures could result. Many floor coverings will not be able to withstand this kind of use. Never install range over vinyl tile or linoleum that cannot withstand high temperatures. Never install range directly over carpeting.

Important Safety Information

Extension Cords

Do not use an extension cord with this product.

Using the Oven

• Do not leave children alone or unattended where a range is hot or in operation. They could be seriously burned.

• Do not allow anyone to climb, stand or hang on the door. They could damage the range and cause severe personal injury.

• Wear proper apparel. Loose fitting or hanging garments should never be worn when using oven. Flammable material could ignite if brought in contact with flame or hot oven surfaces which may cause severe burns.

• Never use range for warming or heating a room. This may cause burns, injuries, or a fire.

• Do not use water on grease fires.

• Do not let grease or other flammable materials collect in or around range.

• Do not repair or replace any part of range unless it is recommended in this manual.

• Use only dry potholders. Moist or damp potholders used on hot surfaces may result in a burn from steam. Do not let a potholder touch the flame. Do not use a towel or a bulky cloth as a potholder.

• Never leave range unattended while cooking. Boilovers can cause smoking and may ignite.

• Only certain types of glass/ceramic, earthenware, or other glazed utensils are suitable for oven use. Unsuitable utensils may break due to sudden temperature change.

• Use care when opening oven door. Let hot air or steam escape before removing or replacing food.

• Do not heat unopened food containers in oven. Build-up of pressure may cause a container to burst and result in injury.

• Keep range vent ducts unobstructed.

• Place oven racks in desired location while oven is cool. If a rack must be moved while oven is hot, use a dry potholder.

• Do not use aluminum foil to line oven bottom or racks. Aluminum foil can cause a fire will seriously affect baking results, and damage to porcelain surface's.

• Do not touch interior surfaces of oven during or immediately after use. Do not let clothing or other flammable materials come in contact with bake or broil burners.

• Other areas of the oven can become hot enough to

cause burns, such as vent openings, window, oven door and oven racks.

• To avoid steam burns, do not use a wet sponge or cloth to wipe up spills on hot cooking area.

• Do not store combustible or flammable materials, such as, gasoline or other flammable vapors and liquids near or in oven.

• Do not clean oven door gasket located on back of the door. Gasket is necessary to seal the oven and can be damaged as a result of rubbing or being moved.

• Do not drape towels or any materials on oven door handles. These items may ignite causing a fire.

OVENS

1. Use Care When Opening Door—Let hot air or steam

escape before removing or replacing food.

2. Do Not Heat Unopened Food Containers—Buildup of

pressure may cause container to burst and result in injury.

3. Keep Oven Vent Ducts Unobstructed.

4. Placement of Oven Racks—Always place oven racks

in desired location while oven is cool. If rack is removed while oven is hot, do not let potholder contact hot heating element in oven.

SELF-CLEANING OVENS

1. Do Not Clean Door Gasket—The door gasket is

essential for a good seal. Care should be taken not to rub, damage, or move the gasket.

2. Do Not Use Oven Cleaners—No commercial oven

cleaner or oven liner protective coating of any kind should be used in or around any part of the liner.

3. Clean Only Parts Listed in Manual.

4. Before Self-Cleaning the Oven—Remove broiler pan,

oven racks, and other utensils.

5. Remove all items from range top and backguard.

GLASS/CERAMIC COOKING SURFACES

1. Do Not Cook on Broken Cooktop—If cooktop should

break, cleaning solutions and spillovers may penetrate the broken cooktop and create a risk of electrical shock. Contact a qualified technician

immediately.

2. Clean Cooktop With Caution—If a wet sponge or

cloth is used to wipe spills on a hot cooking area, be careful to avoid a steam burn. Some cleaners can produce fumes if applied to a hot surface.

VENTILATION HOODS

1. Clean Ventilation Hoods Frequently—Grease should not be allowed to accumulate on hood or filter.

2. When flaming foods under hood, turn fan off. The fan, if operating, may spread the flame.

Due to the nature of cooking, fires can occur as a result of over cooking or excessive grease. Though a fire is

unlikely, if one occurs, proceed as follows:

Surface Element Fire

1. Smother the fire with a nonflammable lid or baking soda, or use a Class ABC or BC extinguisher. Not water. Not salt. Not flour.

2. As soon as it is safe to do so, turn the surface controls to “OFF”.

Oven Fires

1. If you see smoke from your oven, do not open oven door.

2. Turn oven control to “OFF”.

3. As an added precaution, turn off power at main circuit breaker or fuse box.

4. Turn on vent to remove smoke.

5. Allow food or grease to burn itself out in oven. Do not open oven door.

6. If smoke and fire persist, call fire department.

7. If there is any damage to components, call an authorized servicer.

Precautions

• Do not cook food directly on range top surface, always

use cookware.

• Do not mix household cleaning products. Chemical

mixtures may interact with objectionable or even hazardous results.

• Do not put plastic items on warm cooking areas. They

may stick and melt.

• Do not slide rough objects across range top surface.

Scratching or metal marking can result.

• Do not use cookware with rough bottoms. They may

scratch smoothtop surface. Glass and ceramic cookware should not be used.

• Do not use damp sponge or dishcloth to clean range

top. A film of soil-laden detergent water may collect on range top. If this should happen, Amana Cleaning Conditioning Cream removes this type of stain.

• Do not leave fat heating unless you remain nearby. Fat

can ignite if overheated by spilling onto hot surfaces.

• Do not allow pots to boil dry as this can cause damage

to cooking surface and pan.

• Do not use range top surface as a cutting board.

• Do not use range for storage or as a display counter.
