Do not know what I'm talking? For this purpose from the instructions S. 8 "The oven":
... A cooling fan protects the oven from overheating. "Cooling fan": The cooling fan switches on when needed and off (Note d AV .: As soon as the cooking space, no matter what function is switched on..!) (Note d AV .: when switching off..!). The warm air escapes above the door (n. D. Verf .: The hot air escapes above the door as soon as it opens, but from the vents escapes always cold, really cold air !!!!!!)
Take a drill from Bosch and drill holes in the wall, while the cooling fan is blowing in your face. So you feel then when cooking and baking (eg pancakes stacked inside the oven) with this product from Bosch. We do not recommend the purchase and return stove.
