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 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).
USING THE COOKTOP BURNERS IMPORTANT: Make sure all cooktop burners are properly installed. 1. To ignite a burner, push down on the burner control knob and turn it counter-clockwise towards the "Hi" position. The clicking sounds indicate the system is igniting. 2. After the cooktop burner lights, release and turn the control knob between Hi, Med, and Low to adjust the flame level.
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. Oversize 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.
COOKTOP CARE CLEANING IMPORTANT: Before cleaning, make sure all controls are off and the cooktop is 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. CONTROL KNOBS • To remove the knobs, be sure the knobs are in the OFF position. • Pull knobs straight away from control panel to remove. Cleaning Recommendation: • The knobs should be cleaned with soap and water.
BURNER BASE • The holes in the burner bases must be kept clean for proper ignition and a complete, even flame. Spillovers should be cleaned immediately since they can clog the openings in the burners. IMPORTANT: Before cleaning, make sure all controls are OFF and the cooktop is cool. Cleaning Recommendation: • Remove the burner cap from the base. Clean the burner cap with hot soapy water, and then rinse it. • Remove the burner base and clean the gas tube opening under the base.
TROUBLESHOOTING First try the solutions suggested here to possibly avoid the cost of a service call.
