| How old is your grill? To the best of my knowledge, the newer grills no longer can accomodate lava rocks or ceramic briquets. I had an older Sunbeam that did, and when it died, I looked around and couldn't find any grills except for some made by Great Outdoors that could accomodate lava rocks. The new Sunbeams have a porcelain coated bar covering the burners that mimics the "flavor bars" of the Weber. I think they stopped using lava rocks to avoid flare-ups. I personally liked them -- it may have been psychological, but I think it gave it more of a barbequed taste. In either case, I just got a new Sunbeam, and there's no place for lava rocks : ( susan |
