Bertazzoni master series 30" 4-burner 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 fan which provides even heat distribution for single and multi-level roasting and baking. A triple-glass door minimises heat loss.
