GENERAL


SURFACE COOKING UNITS

• If the top burner flame goes out,gas is still flowing to the burner until the knob is turned to the “OFF” position.Do not leave the burners “ON” unattended.

• Use Proper Pan Size – This appliance is equipped with one or more surface units of different sizes. Select utensils having flat bottoms large enough to cover the surface unit heating element. The use of undersized utensils will expose a portion of the heating element to direct contact and may result in ignition of clothing. Proper relationship of utensil to burner will also improve efficiency.

• Never Leave Surface Units Unattended at High Heat

Settings – Boil overs may cause smoking and greasy spillovers may ignite.

• Make Sure Reflector Pans or Drip Bowls Are in Place –

Absence of these pans or bowls during cooking may subject wiring or components underneath to damage.

• Protective Liners – Do not use aluminum foil to line surface unit drip bowls or oven bottoms, except as suggested in the manual. Improper installation of these liners may result in a risk of electric shock, or fire.

• Glazed Cooking Utensils – Only certain types of glass, glass/ceramic, ceramic, earthenware, or other glazed utensils are suitable for range-top service without breaking due to the sudden change in temperature.

• Utensil Handles Should Be Turned Inward and Not Extend

Over Adjacent Surface Units – To reduce the risk of burns, ignition of flammable materials, and spillage due to unintentional contact with the utensil, the handle of a utensil should be positioned so that it is turned inward, and does not extend over adjacent surface units.

• Be sure you know which knobs operate each burner.

Make sure you turned on the correct burner.

• To prevent burns, always be sure that the controls for all burners are at the “OFF” position and all grates are cool before attempting to remove them.

SELF-CLEAN OVENS

• 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.

• 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 oven.

• Clean in the self-clean cycle only parts listed in this

manual. Before self-cleaning the oven, remove the broiler pan and any utensils from the oven.

• Never keep pet birds in the kitchen – the health of birds is extremely sensitive to the fumes released during an oven selfclean cycle. Fumes may be harmful or fatal to birds. Move birds to well-ventilated room.

• Important Instruction – In the event the self-clean mode “F” code goes on, or three long beeps sound, oven is malfunctioning in the self-clean mode. Turn off or disconnect appliance from power supply and have serviced by a qualified technician.

VENTILATING HOODS:

• Clean Ventilating Hoods Frequently – Grease should not be allowed to accumulate on hood or filter.

• When flaming foods under the hood, turn the fan on.

OVEN

• Use Care When Opening Door – Let hot air or steam escape before you remove or replace food in the oven

• Do Not Heat Unopened Food Containers – Build-up of pressure may cause container to burst and result in injury.

• Keep Oven Vent Ducts Unobstructed – the oven vent is located above the center burner. This area could become hot during oven use. Never block this vent and never place plastic or heat-sensitive items on vent.

• Placement of Oven Racks – Always place oven racks in desired location while oven is cool. If rack must be moved while oven is hot, do not let potholder contact hot heating element in oven.

• Do Not allow aluminum foil or meat probe to contact heating elements.

Bake burner operates during bake mode. Bake can be used to cook foods which are normally baked.

Oven must be preheated.

Upper Oven

Convection Bake / Roast Mode(For the Lower oven only)

Convection bake should be used for cooking casseroles and roasting meats. Oven should be preheated for best results when using convection bake. The convection cooking modes automatically reduce the oven temperature by 25 °F (14 °C).

The display shows the changed temperature.

• This feature is called auto conversion.

• The range comes with this feature enabled.

• The oven fan runs while convection baking.

If the door is left open for longer than 30 seconds during baking, the fan stops.

Broil Mode(For the Upper oven only)

Broil burner operates during broil mode. Broil can be used to cook foods which are normally broiled.

Preheating is not required when using broil. All foods should be turned at least once except fish, which does not need to be turned.

1. TO TURN ON THE SURFACE BURNER

1. Be sure all the surface burners are placed in their respective positions.

2. Push the control knob in and turn it to the

“LITE” positions.

3. You can hear a little CLICKING noise - the sound of the electric spark igniting the burners.

4. To control the flame size, turn the knob. If the knob stays at “LITE”, it will continue to click.

NOTE:

• When turning a burner to LITE, all the burners spark. Do not attempt to disassemble or clean around any burner while another burner is on. An electric shock may result, which could cause you to knock over hot cookware.

• The medium (left rear) and the large (left front) burners are the primary burners for most cooking. These generalpurpose burners can be turned down from “HI” to “LO” suit a wide range of cooking needs.

• The extra large burner (right front) is the maximum output burner. Like the other four burners, it can be turned down from “HI” to “LO” for a wide range of cooking applications.

• The extra large burner can be also turned down to “LO” for a low simmer setting almost like the small burner.

Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures

2. ALL units in the first few days of use should be checked for mis-wiring or loose connections

1. All/tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per-volt DC, or greater.

2. Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.

3. Resistance checks must be made with the power cord unplugged from the outlet, and with the wiring harness or connectors disconnected.

WARNING

• Turn off the electrical supply and gas supply going to the range.

• Replace all panels and parts before operating

• Reconnect all grounding devices after servicing

Fan noise

Fan and burner operating in the oven at normal bake

Burners are not lighting properly after cleaning the cooktop surface.

When lighting just one burner, clicking noise is heard from all the burners.

My range is still dirty after running the

EasyClean® cycle. What else should

I do?

I tried scrubbing my oven after running EasyClean®, but some soils still remain. What can I do?

Soils on my oven walls are not coming off. How can I get my walls clean?

Will EasyClean® get all of the soils and stains out completely?

Are there any tricks to getting some of the stubborn soils out?

Is it safe for water to spill into the oven bottom vents during cleaning?


• A convection fan may automatically turn on and off.

- This is normal.

It is normal for the fan to run while preheating during a regular bake cycle.

The fan motor may run periodically during a regular bake cycle. This is to ensure even baking results.

The bake burner turns off if the door is left open during baking.

If the door is left open for longer than 30 seconds during baking, the bake burner turns off. The bake burner turns back on automatically once the door is closed.

Make sure that the burner heads and caps are completely dry and properly positioned.

This is normal. Electric spark igniters from the burners cause the clicking noise. All the spark igniters on the cooktop will activate when igniting just one burner.

The EasyClean® cycle only helps to loosen light soils in your oven range to assist in hand-cleaning of your oven. It does not automatically remove all soils after the cycle. Some scrubbing of your oven range is required after running the EasyClean® cycle.

EasyClean® feature works best when the soils are fully soaked and submerged in water before running the cycle. If soils are not sufficiently soaked in water, it can negatively affect cleaning performance. Repeat the EasyClean® process using sufficient water. Sugar-based and certain grease soils are especially hard to clean. If some stubborn soils remain, use the Self Clean feature to thoroughly clean your oven.

Soils on the side and rear walls of your oven range may be more difficult to fully soak with water. Repeat the EasyClean® process with more than the 1/4 cup (2 oz) spray recommended.

It depends on the soil type. Sugar-based and certain grease stains are especially hard to clean. Also, if stains are not sufficiently soaked in water, then this can also negatively affect cleaning performance. If stubborn or built-up stains remain, use the Self Clean feature. Refer to the Self Clean section of your owner's manual.

Scraping the soils with a plastic scraper before and during handcleaning cleaning is recommended. Fully saturating soils with water is also recommended. However, certain types of soils are harder to clean than others. For these stubborn soils, the

Self Clean cycle is recommended. Consult the Self Clean section of your owner's manual for details.

Some water spillage into the oven bottom vents (gas range) is okay.

However, it is recommended to try avoid spilling too much water into the vents.

8-5



IIs it safe for my broil burner or heater element to get wet during

EasyClean®?

Do I need to use all 11/4 cup (10 oz) of water for EasyClean®?

I see smoke coming out of my oven range’s cooktop vents during

EasyClean®. Is this normal?

How often should I use EasyClean®?

What is required for EasyClean®?

Can I run the EasyClean® cycle on both of my ovens at once?


Yes. The broiler burner or heater element may get a little wet during cleaning.

However, direct spray onto the broil burner and heater elements is not necessary because these are self-cleaning during regular use.

Yes. It is highly recommended that 1cup (8 oz) of water be sprayed or poured on the bottom and additional 1/4 cup (2 oz) of water be sprayed on walls and other soiled areas to fully saturate the soils for better cleaning performance.

This is normal. This is not smoke. It is actually water vapor (steam) from the water in the oven cavity. As the oven heats briefly during

EasyClean®, the water in the cavity evaporates and escapes through the oven vents.

EasyClean® can be performed as often as you wish. EasyClean® works best when your oven is LIGHTLY soiled from such things as

LIGHT grease splatter and small drops of cheese. Please refer to the

EasyClean® section in your owner's manual for more information.

A spray bottle filled with 1 1/4 cup of water, a plastic scraper, a nonscratch scrubbing pad and a towel. You should not use abrasive scrubbers such as heavyduty scouring pads or steel wool.

Yes. You can run the EasyClean® cycle on both ovens at the same time. Some oven surfaces will be hot after the cycle completes running. Avoid leaning or resting on the oven door glass while cleaning the oven cavities. You can not run the Self Clean cycle on both ovens at the same time.
