I had my range installed this morning by my propane company. They were having a bit of a time knowing how to switch it from gas to propane. The small book didn't have any information on this at all. They figured it out eventually. I called kucht and customer service talked with the installer and they had it figured out. I also asked customer service how I take the door off because I'm getting my free door this coming week. Taking off the door wasn't in the book either. But with all that being said I think Kucht should have a manual that has much more details like for instance how do you clean the grates and what size bulb goes inside the oven. Those are not in the book either. I do like the look of the stove and the oven racks roll out which is a nice feature. I can't give a review on the performance of the stove because I just put it in today and I hope I don't have any problems with it.
