Five Dual Stacked burners with low-profile continuous grates allow you to slide pots from burner to burner without lifting. All burners feature True Simmer so you can simmer without boiling, melt without scorching. Burners re-ignite automatically, if accidentally blown out. Sealed burners and deep stainless steel drip pans make clean-up easy. Cast iron, porcelain coated, grates are dishwasher safe.
