Made in Italy for SUMMIT, our deluxe gas-on-glass cooktops offer the ideal cooking experience for modern kitchens. The GC443BGL is a four-burner island cooktop made from tempered black glass for a sleek look that's easy to clean. Continuous cast iron grates let you slide cookware back and forth for added convenience. The combination of two 4,350 and two ultra 10,300 BTU burners allows you to accommodate all sorts of cooking, from a saut(eback) to gentle simmer. The sealed Sabaf® burners feature cast iron tops for lasting durability and easy cleanup. The GC443BGL uses electronic spark ignition and comes preset for natural gas operation. We include a conversion kit that lets you adjust for LP gas. Safety features include push-to-turn knobs, sealed burners, and a thermocouple flame failure protection to ensure gas will turn off if the flame is extinguished.
