The Cookshield Finish on the KitchenAid-KCGS556ESS 36" Stainless Steel Sealed Burner Natural Gas Cooktop is scratch resistant and protects it from stains that have the tendency to develop from cooking with high temperatures, helping maintain the aesthetic appeal of this stylish cooktop. Versatility in the 20K BTU burner allows you to easily sear steak but also simmer your favorite sauce with its low heat feature. Confidently move a heavy pot across the full-width cast iron grates without lifting and risking the chances of spillage. The electronic ignition also automatically lights the burners without a standing pilot light.
