• This appliance is not intended for storage.

READ AND SAVE THESE INSTRUCTIONS

• Do Not Use Water on Grease Fires – Smother fire or flame or use dry chemical or foam-type extinguisher.

• Use Only Dry Potholders – Moist or damp potholders on hot surfaces may result in burns from steam. Do not let the potholder touch hot heating elements. Do not use a towel or other bulky cloth.

• Never Leave Surface Units Unattended at High Heat Settings – Boilover causes smoking and greasy spillovers that may ignite.

• Glazed Cooking Utensils – Only certain types of glass, glass/ceramic, ceramic, earthenware, or other glazed utensils are suitable for rangetop service without breaking due to sudden changes 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.

• Disconnect power before servicing.

• Proper Installation – The appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.1-02. In Canada, the appliance must be electrically grounded in accordance with the Canadian
  Electrical Code. Be sure your appliance is properly installed and grounded by a qualified technician.

• Injuries may result from the misuse of appliance doors or drawers such as stepping, leaning, or sitting on the doors or drawers.

• Maintenance – Keep the range area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

• Do not let cooking grease or other flammable materials accumulate in or near the range. Grease in the oven or on the cooktop may ignite.

• Top burner flame size should be adjusted so it does not extend beyond the edge of the cooking utensil. This instruction is based on safety considerations.

• Do not use replacement parts that have not been recommended by the manufacturer (e.g. parts made at home using a 3D printer).

• Clean Cooktop With Caution – If a wet sponge or cloth is used to wipe spills on a hot cooking area, be careful to avoid steam burn. Some cleaners can produce noxious fumes if applied to a hot surface.

• Use Care When Opening Door – Let hot air or steam escape before removing or replacing food.

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

• Keep Oven Vent Ducts Unobstructed.

• Never broil with the door open. Open-door broiling is not permitted due to overheating of control knobs.

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

• Care must be taken to prevent aluminum foil and meat probes from contacting heating elements.

• DO NOT TOUCH HEATING ELEMENTS OR INTERIOR SURFACES OF OVEN – Heating elements may be hot even though they are dark in color. The interior surfaces of an oven become hot enough to cause burns. During and after use, do not touch, or let clothing or other flammable materials contact heating elements or interior surfaces of the oven until they have had sufficient time to cool. Other surfaces of the appliance may become hot enough to cause burns – among these surfaces are cooktop, burners, grates, oven vent openings and surfaces near these openings, oven doors,  windows of oven doors, and crevices around the oven doors.

• Top burner flame size should be adjusted so it does not extend beyond the edge of the cooking utensil.

COOKTOP USE

Read the instructions before installing or using this appliance.

• This appliance shall be installed in accordance with the regulations in force and only used in a well-ventilated space.

• The use of gas-cooking appliances results in the production of heat and
  moisture in the room in which it is installed. Ensure that the kitchen is well-ventilated: keep natural ventilation holes open or install a mechanical
  ventilation device (mechanical extractor hood).

• Prolonged intensive use of the appliance may call for additional ventilation, for example, the opening of a window, or more effective ventilation, for example, increasing the level of mechanical ventilation where present.

IGNITION AND OPERATION OF THE BURNERS
To ignite a burner, push down on the burner knob and rotate it counterclockwise until the knob indicator is aligned with the ignite icon. Release the knob and adjust the flame intensity by further rotating the knob counterclockwise from MAX (maximum) to MIN (minimum).
NOTE: For models with a flame failure safety device – Once the flame is lit, hold the knob depressed for about 3-4 seconds until the device keeps the burner automatically lit. If the burner fails to ignite, wait one minute for the gas to dissipate before attempting to reignite.
To turn off the burner, rotate the knob clockwise until the indicator on the knob is aligned with OFF.

POWER FAILURE
In case of prolonged power failure, the surface burners can be lit manually. Hold a lit match near a burner and turn the knob counterclockwise until the indicator is aligned with MAX. After the burner is lit, turn the knob to the desired setting.
In the case of unintentional flame extinguishing, the safety valve intervenes by shutting off the gas to the burners.
The electric igniter must not be actuated for longer than 15 seconds. Should the burner not light, or should the burner be unintentionally turned off, immediately close the burner, and wait at least 1 minute before repeating. Once ignited, adjust the flame as desired.
For lower gas consumption and a better result, use saucepans with a diameter matching the diameter of the burner, to avoid the flame coming up around the sides of the saucepan. See the Container Table. Use only flat-bottomed pans. As soon as the liquid starts to boil, turn the flame down to a level sufficient to maintain boiling.
COOKWARE
MATCH PAN DIAMETER TO FLAME SIZE
The flame should be the same size as the bottom of the pan or smaller. Do not use small pans with high flame settings as the flames can lick up the sides of the pan. Oversized pans that span two burners are placed front to rear, not side to side.
USE BALANCED PANS
Pans must sit level on the cooktop grate without rocking. Center the pan over the burner.
USE A LID THAT FITS PROPERLY
A well-fitting lid helps shorten the cooking time. Flat, heavy bottom pans provide even heat and stability.
CONTAINER TABLE

OVEN USE

WARNING

NEVER cover any slots, holes, or passages in the oven bottom or cover an entire rack with materials such as aluminum foil. Doing so blocks airflow through the oven and may cause carbon monoxide poisoning. Aluminum foil linings may also trap heat, causing a fire hazard. Reset all controls to the OFF position after using a programmable timing operation. No attempt should be made to operate the appliance during power failure. An air curtain or other overhead range hood, which operates by blowing a downward airflow onto a range shall not be used in conjunction with a gas range.

OVEN CONTROLS
The Thermostat knob and Cooking-mode knobs are used together to select Oven Modes.

THERMOSTAT KNOB
Push in on the Thermostat knob, and then turn the knob to any baking temperature or broil to automatically ignite the bake burner or the broil burner.
Bake
THERMOSTAT RANGE: 140°F (60°C) TO MAX 500°F (260°C) The Bake mode uses heat from the lower element to cook food. When using this mode to prepare baked goods such as cakes, cookies, and pastries, always preheat the oven first and place food centrally near the middle racks.
Broil
THERMOSTAT RANGE: Broil
The Broil mode uses intense heat from the upper element to sear foods. Ideal for toasting, melting cheese, browning, and searing surface. Food should be placed near the upper racks, and should not be cooked for too long on each side of the food. It is not necessary to preheat when using this mode.
NOTE: Except for timed cooking, the oven will remain on until the Thermostat knob is returned to the OFF position.

COOKING-MODE KNOB

Light
The Light mode turns on oven light inside the oven.
Conv Fan (Convection Fan)
The Convection Fan mode uses air movement from the fan to enhance cooking evenness across multiple racks. Cooking times may be slightly longer for multiple racks than what would be expected for a single rack.

TIPS AND TECHNIQUES

Bake
Baking is cooking with heated air. Both upper and lower elements in the oven are used to heat the air but no fan is used to circulate the heat.
Follow the recipe or convenience food directions for baking temperature, time, and rack position. Baking time will vary with the temperature of the ingredients and the size, shape, and finish of the baking utensil.
General Guidelines

• For best results, bake food on a single rack with at least 1″ – 1½” (2.5 – 3 cm) space between utensils and oven walls.
• Use one rack when selecting the bake mode.
• Check for doneness at the minimum time.
• Use metal bakeware (with or without a non-stick finish), heatproof glass, glass-ceramic, pottery or other utensils suitable for the oven.
• When using heatproof glass, reduce the temperature by 25°F (15°C) from recommended temperature.
• Use baking sheets with or without sides or jelly roll pans.
• Dark metal pans or nonstick coatings will cook faster with more browning. Insulated bakeware will slightly lengthen the cooking time for most foods.
• Do not use aluminum foil or disposable aluminum trays to line any part of the oven. Foil is an excellent heat insulator and heat will be trapped beneath it. This will alter the cooking performance and can damage the finish of the oven.
• Avoid using the opened door as a shelf to place pans.
• See Troubleshooting for tips to Solving Baking and Roasting Problems.

RANGE CARE

CLEANING
IMPORTANT: Before cleaning, make sure all controls are off and the oven and cooktop are cool. Always follow label instructions on cleaning products. Soap, water, and a soft cloth or sponge are suggested first unless otherwise noted. Do not use abrasive cleaning products.

EXTERIOR PORCELAIN ENAMEL SURFACES

• Food spills containing acids, such as vinegar and tomato, should be cleaned as soon as the entire appliance is cool. These spills may affect the finish.

Cleaning Method:

• Glass cleaner, mild liquid cleaner, or nonabrasive scrubbing pad: Gently clean around the model and serial number plate because scrubbing may remove numbers.

EXTERIOR STAINLESS STEEL
NOTE: Do not use soap-filled scouring pads, abrasive cleaners, Cooktop Polishing Cream, steel-wool pads, gritty washcloths, or some paper towels. Damage may occur, even with one-time or limited use.

• Rub in direction of the grain to avoid damage.

Cleaning Methods:

• Liquid detergent or all-purpose cleaner: Rinse well with clean water and dry with soft, lint-free cloth.
• Stainless Steel Cleaner and Polish. Vinegar for hard water spots.

OVEN DOOR EXTERIOR
Cleaning Method:

• Glass cleaner and paper towels or nonabrasive plastic scrubbing pad: Apply glass cleaner to soft cloth or sponge, not directly on the panel.

PORCELAIN-COATED GRATES AND CAPS

• Clean as soon as the cooktop, grates, and caps are cool.
• Food spills containing acids, such as vinegar and tomato, should be cleaned as soon as the cooktop grates and caps are cool. These spills may affect the finish.
• To avoid chipping, do not bang grates and caps against each other or hard surfaces such as cast iron cookware.
• Do not reassemble caps on burners while wet.

Cleaning Method:

• Nonabrasive plastic scrubbing pad and mildly abrasive cleanser.

BURNER SPREADER
Cleaning Method:

• Wash the burner spreader frequently with boiling water and detergent to remove any deposits which could block the flame outlet.
