Forget the covers. Yes, I took mine off, and placed 2 foil disposable cookie sheets on top of the burners, then I placed some lava rocks on top of them. Now, I have a flare free and mess free grill. When the cookie sheets get dirty, I just replace them and I will have a clean grill all the time. The grill will cook a little slower using this method, but you’ll never have burned or over cooked food. Note I did place an old fashion rack underneath the foil sheets for extra support. You can find these racks in any Hardware store, they're made by the same company and they run about $12.00.
