DESC: The high-output gas burners accommodate all of your cooking needs and are staggered for convenient cooking with large utensils. The burners ignite when controls are turned to any "on" position and precise flame level is maintained by brass valves. Dacor's Perma-Flame? feature ensures that your gas flame automatically restarts if it goes out. The cooktop's surface is completely sealed. There is no place for spills to hide, because they're easily cleaned. There is only one grate for each pair of burners. Simply remove a grate and wipe spills up with a damp sponge. Cleaning couldn't be easier.
