A:AnswerHello Davud, a range or wall oven with all racks in the oven cavity will preheat to 350°F in: 12 - 15 minutes (+/- 5 minutes). We hope this helps.
A:AnswerHi Chea, you do not have to use WiFi with this Oven. Unfortunately, we do not have any Double Ovens that will fit in your space. We are sorry for any inconveniences this may cause.
