OPERATION COOKTOP BEFORE USING THE COOKTOP Read all instructions before using. WARNING • Make sure all burners are in their correct locations and fully assembled before attempting to operate any burner. • Never leave the surface burners on unattended. Boilovers may cause smoke and greasy spillovers that may ignite. • Do not use aluminum foil to line or cover the cooktop, grates, or any other part of the cooktop. Doing so may result in carbon monoxide poisoning, overheating of the cooktop surfaces, or fire.
IMPORTANT: • The use of a gas-cooking appliance 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 opening of a window, or more effective ventilation, for example increasing the level of mechanical ventilation where present.
Selecting a Flame Size Watch the flame, not the control knob, as you reduce heat. Match the flame size on a gas burner to the cookware being used for fastest heating. NOTE: • Never let the flames extend up the sides of the cookware. Flames larger than the bottom of the cookware will not heat faster and may be hazardous. In Case of Power Failure In case of a power failure, you can light the gas surface burners on your range with a match.
USING THE PROPER COOKWARE Aluminum Medium-weight cookware is recommended because it heats quickly and evenly. Most foods brown evenly in an aluminum skillet. Use saucepans with tight fitting lids when cooking with minimum amounts of water. Cast-Iron If heated slowly, most skillets will give satisfactory results. Stainless Steel This metal alone has poor heating properties and is usually combined with copper, aluminum or other metals for improved heat distribution.
NOTE: • The flame should not extend beyond the bottom edge of the cookware. Oversized cookware that spans two burners should be placed front to rear, not side to side. • Use balanced cookware that sits level on the cooktop grate without rocking. Center the cookware over the burner. • Use a lid that fits properly. A well-fitting lid helps shorten the cooking time. • Match the size of the cookware to the amount of food being cooked to save energy when heating.
OVEN BEFORE USING THE OVEN Read the instructions for each feature and cooking mode in this manual carefully before using the oven. 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. Damage from improper use of these items is not covered by the product warranty. • Foil may be used to catch spills by placing a sheet on a lower rack, several inches below the food.
WARNING FOOD POISONING HAZARD • Do not let food sit in oven more than one hour before or after cooking. Doing so can result in food poisoning or sickness. • Foods that can easily spoil such as milk, eggs, fish, meat or poultry, should be chilled in the refrigerator first. Even when chilled, they should not stand in the oven for more than 1 hour before cooking begins, and should be removed promptly when finished cooking.
OVEN DOOR Oven burners and, if in operation, convection fan will temporarily shut off any time door is opened, and will resume when door is closed within 3 minutes. NOTE: • Do not leave the door open any longer than necessary. If the door is left open too long for over 3 minutes, the cooking mode will be automatically cancelled.
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. Rack Positions For best cooking results, adjust rack so food is placed at the center of the oven. For most foods this will be rack position #3 or #4. For larger foods like roasts and turkey, move the rack position down to #2 or #1 to keep the food centered in the oven.
PREHEATING Preheating is generally desirable, although not absolutely necessary in all circumstances. • For oven modes that utilizes preheat, the control will automatically enter preheat mode and show "100°F" after START/OK is pressed to turn on the oven. - When the oven temperature reaches 100°F, the display will show the current oven temperature, and will continue to show the oven temperature increasing until the set temperature is reached.
COOKING MODES The various baking modes (Bake, Conv Bake, Conv Roast, and Pizza) have a 10-hour time limit, after which the control will automatically end the baking mode. Broil and Warm modes have a 3-hour time limit. If desired, these modes can be restarted after the time limit expires.
BAKE The Bake mode uses heat from the lower heating element to cook food. This mode works best with food placed on a single rack. Always preheat the oven first and place food centrally near the middle racks. Setting the Bake Mode 1. Press or repeatedly to select "Bake" in the display. 2. Press START/OK.

As the oven preheats and reaches 100°F, the display will show the current oven temperature, and will continue to show the oven temperature increasing until the set temperature is reached. Once the oven reaches the set temperature, a tone sounds. 7.
CONV ROAST The Convection Roast mode uses heat from both upper and lower elements and 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. Foods are crispy brown on the outside while staying moist on the inside. A meat probe may be used with this feature.
NOTE: • Do not leave the door open any longer than necessary when placing food. If the door is left open too long for over 3 minutes, the cooking mode will be automatically cancelled. 8. Press CANCEL/OFF when cooking is finished, and remove the food from the oven. If a Cook Time is set and the countdown reaches 00:00, the oven turns off automatically. The display shows "End" and a cook end tone sounds for 1 minute or stops when the oven door is opened. NOTE: • The oven fan runs while convection roasting.

WARM The Warm mode uses heat from the lower heating element to maintain oven temperature at around 175°F (79°C). It will keep cooked food warm for serving up to 3 hours after cooking has finished. Cover foods that need to remain moist and do not cover foods that should be crisp. Preheating is not required. Setting the Warm Mode 1. Place the hot food in the oven. 2. Press or repeatedly to select "Warm" in the display. 3. Press START/OK. "Cooktime" appears and "00:00" (hour:minute) flashes in the display.
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. Setting the Broil Mode 1. Press or repeatedly to select "Broil" in the display. 2. Press START/OK. The default set temperature "HI" flashes in the display. 3.
TIPS AND TECHNIQUES BAKE Baking is cooking with heated air. The lower element in the oven is 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 ingredients and the size, shape and finish of the baking utensil. • For best results, bake food on a single rack with at least 1" - 1 ¹⁄₂" (2.5 - 3 cm) space between utensils and oven walls.
