I have done this on occasion with other grills. It works , but it's not ideal since it's had to regulate the temp on many.

I would advise not to. It would trap too much heat and I'm sure you would see some detrimental effects. A stand alone electric griddle is a good option for the most part. Check with Wolf about use of a griddle I think they advise not to.

You are going to like the grill. Super hot and chars like no tomorrow. I use mine a lot and after fretting about the decision it was a good way to go.

Have fun

I have the grill and Wolf does advise against putting anything on it other than food on it. If you get the grill, you'll see why as soon as you cut it on . . .

I've used cast iron griddle plates on standard burners and they work ok. Nothing like a real griddle but for me, the grill would get more use. We would only pull out the griddle if we had guests staying with us and we wanted to make a big pancake breakfast. For regular Sunday morning pancakes, we just pull out the kamal. The advantage of a real griddle is that you get temp control rather than just low-high flame like you get on a grill or standard burner.
