The combination of 6 Monobloc brass burners and cast iron contour grates let you cook like a professional. The grates are designed for maximum space to fit pots and pans of different sizes with ease. The extra powerful 19,000 BTU power burners boil water faster than any burner in their class. Boil pasta, sear meat or stir fry with a wok on the 2 power burners with dual ring flame; or delicately melt chocolate or warm cream on the simmer burner. Safety is designed-in with the 100% fail-safe thermocouple technology. It instantly shuts off the gas if the flame goes out, offering peace of mind and protection for your family and home.
