Four Dual Stacked burners go from highest searing heat to minutest breath of flame for melting and simmering. With the low-profile continuous grates, you can slide pots from burner to burner without lifting. Sealed burners and stainless steel deep drip pans make clean-up easy. Burners re-ignite automatically if accidentally blown out. Cast iron, porcelain coated, grates are dishwasher safe.
