Bertazzoni Professional series gas range. This versatile size works just as well in a new kitchen design or with existing cabinetry. The cooktop has four burners including a dual-ring power burner, a high-efficiency burner with separately controlled flames. The oven with gas broiler has a balanced air-flow convection fan which provides even heat distribution for single and multi-level roasting and baking. The oven includes telescopic glide shelves and soft-motion door hinges. A triple-glass door minimizes heat loss.
