Page 22
CAUTION • Never cook directly on the glass. Always use cookware. • Do not use the glass cooktop surface as a cutting board. • Do not slide metal or glass across the cooktop surface. Cookware with rough or uneven bottoms can mark or scratch the cooktop surface. •...
COOKING AREAS The cooking areas on your range are identified by permanent circles on the glass cooktop surface. For the most efficient cooking, fit the pan size to the element size. Pans should not extend more than 1/2" to 1" beyond the cooking area. When a control is turned on, a glow can be seen through the glass cooktop surface.
WARMING ZONE WARNING FOOD POISON HAZARD Bacteria may grow in food at temperatures below 140°F. • Always start with hot food. Do not use the warming zone to heat cold food. • Do not use the warming zone for more than 2 hours. The warming zone, located in the back center of the glass surface, will keep hot, cooked food at serving temperature.
USING THE COOKTOP ELEMENTS Turning on a Single Element 1. Select a single element, and find its control knob. 2. Push the control knob in and turn it in either direction to the desired setting. 3.

Page 27
Choosing Cookware The cookware material determines how evenly and quickly heat is transferred from the surface element to the pan bottom. Recommended • Aluminum - Excellent heat conductor. Some types of food will cause it to darken (anodized aluminum cookware resists staining and pitting).
OVEN BEFORE USING THE OVEN Read all instructions before using. CAUTION • Do not use any type of foil or oven liner to cover the oven bottom. These items can trap heat or melt, resulting in damage to the product and risk of shock, smoke or fire.
OVEN VENT Areas near the vent may become hot during operation and may cause burns. Avoid placing plastics near the vent as heat may distort or melt the plastic. Do not block the vents (air openings) of the range. They provide the air inlet and outlet that are necessary for the range to keep cool and operate properly with correct combustion.
Removing Racks 1. Pull the rack straight out until it stops. 2. Lift up the front of the rack and pull it out. Replacing Racks 1. Place the end of the rack on the support. 2. Tilt the front end up and push the rack in.
Some foods are more robust and may have acceptable results without preheating. These foods include large pieces of meat (whole roasts, hams, or poultry) where the total cooking time is much longer than the time required to preheat. These foods also include frozen potato products and frozen processed dinners that, by their nature and design, are more robust to baking variations.
PIZZA The Pizza mode uses heat from the upper and lower heating elements and adopts customized heating algorithm to optimize baking performance for pizza, which is also ideal for pastries and cakes with wet covering and little sugar and damp desserts in moulds, or dishes requiring more heat in the lower area.
BAKE The Bake mode uses heat from the lower heating element primarily and the upper heating element to achieve exceptional baking performance. This mode works best with food placed on a single rack. 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 The Broil mode uses intense heat from the upper heating element to sear foods. This mode works best for tender cuts of meat, fish, and thinly cut vegetables, and is 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.
CONVECT ROAST The Convection Roast mode uses heat from both upper and lower elements and hot air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Ideal for roasting meats and poultry. Heated air circulates around the food from all sides, sealing in juices and flavors.
CONVECT BAKE The Convection Bake mode uses heat from the lower heating element primarily and the upper heating element and hot air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Always preheat the oven first. Baking times may be slightly longer for multiple racks than what would be expected for a single rack.
PROOF The Proof mode uses heat from the oven lights and air movement from the convection fan to maintain a gently warm oven temperature at around 86°F (30°C) for rising yeast-leavened products before baking. Preheating is not required. Place dough centrally near the middle racks, and cover dough well to prevent drying out.
COOK TIME Set the oven to cook for a specific length of time up to 12 hours and the oven turns off automatically at the end of the cooking time. This feature can only be used with the Bake, Keep Warm, Convect Roast, Convect Bake modes, and may be set at any point during the oven cooking cycle.
DELAY Set the oven to turn on at a specific time of day within the next 12 hours. This feature can only be used with the Bake, Keep Warm, Convect Roast, Convect Bake, Proof, Self Clean, and Steam Clean modes. Cook Time can be set after Delay for a delayed timed cook.

4. Set the start time of day. (Press 0, 4, 3, and 0. Use the DELAY button to switch between AM and PM if needed.) 5. Press START/ENTER, and place the food in the oven. "DELAY START" is shown in the display, and the clock alternates between the current time of day and the time when the oven will turn on.
USING THE SABBATH MODE The Sabbath mode complies with Jewish Sabbath requirements, and is typically used on the Jewish Sabbath and Holidays. Some of these standards that will be noticed by the consumer include the disabling of tones, disabling of oven lights, and delays of about 30 seconds to one minute on display changes.

• Dark metal pans may be used. Note that food may brown faster when using dark metal bakeware. • The number of racks used is determined by the height of the food to be cooked. • Baked items, for the most part, cook extremely well in convection. Don’t try to convert recipes such as custards, quiches, pumpkin pie, or cheesecakes, which do not benefit from the convection-heating process.
