Bertazzoni Ranges have a hidden lower bake element. Top broil element is open.

I'm sure others will chime in but the manual will let you know how to do the burn off. That should help some. It also tells you how to wipe it down prior. I would do that before using it at all. And yes, the fan will continue to run (and make noise) any time the oven is on.

Do NOT toss the thing out!!! It's very helpful in that it raises a pot slightly, allowing an even lower temperature to be achieved: this is perfect for cooking rice, for example, or a delicate sauce. I use mine so much, I acquired a second from Bertazzoni, to use on the inner ring of the double burner. Although it seems so many forum posts are about finding the highest power appliance possible, I find I need the lowest possible for many things, far more often that I need high power (except for my wok).

Thanks Rococogurl! We did figure out the thing about cracking the door when turning it on. Do you (or does anyone) know whether there are two visible flames on the floor of the oven? I see two similar holes, and a flame appears in the one on the left. I thought maybe that was the issue. Will try asking Bertazzoni tomorrow, too.
