FEATURES CONVECTION FAN The convection fan increases air movement and circulates heat within the oven to improve heat distribution on multiple racks and enhance cooking evenness while cooking with single or multiple racks. Cooking times may be slightly longer for multiple racks than what would be expected for a single rack. • Press Convection Fan to turn the oven convection fan on or off. NOTE: • The convection fan turns on for Bake mode only.
OPERATION GAS SURFACE BURNERS BEFORE USING THE GAS SURFACE BURNERS 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.
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 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. 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.
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. It is normal for steam to be visible when cooking foods with high moisture content.
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 #2 or #3. For larger foods like roasts and turkey, move the rack position down to #1 or #2 to keep the food centered in the oven. When using multiple racks simultaneously, try to space the food out around the oven center (rack position #1 and #3 or #2 and #4 for two racks).
OVEN CONTROLS The appearance of the knob may vary from what is shown in the manual. Convection fan button Thermostat knob (°F) Light button Thermostat Knob The Thermostat knob is used to select oven cooking modes. OFF 250 400 BROIL OFF position BAKE (250°F) position BAKE (400°F) position BROIL position Convection Fan • Push the Convection Fan button to turn the convection fan On or Off. Light • Push the Light button to turn the oven lights On or Off.
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. 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 or lower racks. Setting the Bake Mode (Example: Set Bake at 375°F.) 1. Adjust oven rack levels as needed. 2. Turn the thermostat knob to select 375°F. The oven turns on and starts preheating.
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. Preheat the oven for about 5 minutes before placing food in the oven. Setting the Broil Mode 1. Adjust oven rack levels as needed and place the food in the oven. 2.
CONVECTION BAKE The Convection Bake mode uses heat from the lower 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. Setting the Convection Bake Mode (Example: Set Convection Bake at 375°F.) 1. Adjust oven rack levels as needed. 2.
TIPS AND TECHNIQUES BAKE Baking is cooking with heated air. The lower heating 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" - 1½" (2.5 - 3 cm) space between utensils and oven walls.
CONVECTION BAKE The convection fan increases air movement and circulates heat within the oven to improve heat distribution on multiple racks and enhance cooking evenness while cooking with single or multiple racks. Reduce recipe baking temperatures by 25°F (15°C). Cooking times may be slightly longer for multiple racks than what would be expected for a single rack. • For best results, foods should be cooked uncovered, in low-sided pans to take advantage of the forced air circulation.
RANGE CARE AND MAINTENANCE 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. NOTE: • Do not clean the oven door gasket. The material of the gasket cannot withstand abrasion. It is essential for the gasket to remain intact. If you notice it becoming worn or frayed, replace it.
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 panel. PORCELAIN-COATED GRATES AND CAPS • Clean as soon as 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.
CONTROL PANEL Cleaning Method: • Glass cleaner and soft cloth or sponge: Apply glass cleaner to soft cloth or sponge, not directly on panel. NOTE: • Do not use abrasive cleaners, steel-wool pads, gritty washcloths or some paper towels. Damage may occur. OVEN CAVITY • Food spills should be cleaned when oven cools. At high temperatures, foods react with porcelain, so staining, etching, pitting or faint white spots can result. Cleaning Method: • Mild detergent and warm water.
TROUBLESHOOTING First try the solutions suggested here to possibly avoid the cost of a service call. COOKTOP PROBLEMS PROBLEM POSSIBLE CAUSE SOLUTION Burner will not ignite There is no power to the range. Make sure electrical plug is plugged into a live, properly grounded outlet. Replace the fuse or reset the circuit breaker. Burner will not operate First time use. Air still in the gas line. Turn on any one of the surface burner knobs to release air from the gas lines.
PROBLEM POSSIBLE CAUSE SOLUTION Burner flame is too high or too low Cooktop gas supply is not correct. Ensure the range is set for the correct gas type. It is factory set for natural gas. If connecting to LP gas, the burners should be converted to LP gas with the orifice kit supplied and the pressure regulator converted to the LP gas setting by a qualified technician. The gas pressure is not correct. Make sure the pressure regulator is installed correctly and the gas line pressure is correct.
OVEN PROBLEMS PROBLEM POSSIBLE CAUSE SOLUTION Strong odor when using new oven Manufacturing protective coating on the oven surfaces. This is normal with a new range and will disappear after a few uses. Packaging materials exist. Double-check that all packaging has been removed from the appliance - check around door sides and inside drawer. Clicking noise can be heard when oven is operating The oven burner cycles on and off to maintain the oven temperature selected.
PROBLEM POSSIBLE CAUSE SOLUTION Oven light is not working properly Light bulb loose or burned-out. Reinsert or replace the light bulb. Touching the bulb with fingers may cause the bulb to burn out. Oven light stays on Door is not closing completely Check for obstruction in oven door. Check to see if hinge is bent or door switch broken. Excessive Moisture on door glass Condensation from cooking foods with high moisture content. This is normal. Condensation will evaporate as oven heats up.
PROBLEM CAUSE Food is dry or has shrunk excessively • Oven temperature too high • Baking time too long • Oven door opened frequently • Pan size too large Food is baking or roasting too slowly • Oven temperature too low • Oven not preheated • Oven door opened frequently • Tightly sealed with aluminum foil • Pan size too small Pie crusts do not brown on bottom or crust is soggy • Baking time not long enough • Using shiny steel pans • Incorrect rack position • Oven temperature is too low Cakes pale, fl
