The 30-inch gas cooktop with cast iron grates and gas-on-glass surface offers control and flexibility to spare. The full-width cast iron grates resist wear and cover the entire surface, so your largest cookware is not restricted to just one or two burners. The two Power™ burners let you quickly and accurately boil water, sear steaks, or stir-fry. Also, the AccuSimmer® burner produces a gradual, gentle heat that is perfect for melting chocolate or simmering sauces. Plus, the modern glass surface is easy to clean. So you get what you need, when you need it, for great results. Every time.
