For correct ventilation, a ventilation opening of 50 mm should be required between the back wall and the floor of the installation cabinet, and a ventilation gap of 5 mm is required between the oven top rim and the furniture lower rim, and between the oven both sides rim and the cabinet, these openings must not be closed by any way. So ensure that the sides are not touching the front edges of the housing. Connect the oven to the power supply.
