Bertazzoni Professional Series, 30in Four-Burner Electric Self-Clean Oven. This versatile size works just as well in a new kitchen design or with existing cabinetry. The cooktop has four gas burners including a triple-ring, high-efficiency burner with separately controlled flames. The electric self-cleaning oven has nine functions, from convection, baking and roasting to warming. The pyrolytic oven linings require no cleaning agents. High temperatures burn off fat and grease leaving a safe, easily disposed of residue. Quadruple-glass door minimises heat loss.
