OVERVIEW RANGE LAYOUT The range you have purchased may have some or all of the items listed. The locations and appearances of the features shown here may not match those of your model. 1. Oven Vent 6. Door Gasket 11. Oven Light 2.
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.
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.
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).

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.
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.
Page 19
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.
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.
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.

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.
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.
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.
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.
Page 28
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.
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.
