Bertazzoni Professional Series 30" single wall oven. The Bertazzoni Design Series 30-inch single oven features the full range of fast and even heating from its twin-fan convection system, as well as traditional non-convection cooking. It is equipped with a powerful, full-width electric grill. Easy-to-use control knobs operate digitally and set the cooking functions through the micro-processor, featuring 'Bertazzoni Assistant' manage-and-memory functions. The clear interface display is well designed for easy setting and monitoring of your cooking. Alternatively, the oven can be operated entirely manually. The exceptional, energy conscious performance is enhanced by advanced insulating materials and doors with quadruple-glass insulation. Soft-motion door hinges keep the door open in any position.
