Wow, I just saw how you have hung the grill grate on the side of the kettle while getting it ready, I Never would have though of that, it always going to the side.
I'd like to tell you that I discovered that completely on my own .......... but I was doing the unthinkable, actually reading the Owners Manual that came with my new Master Touch Kettle, and found it there. The handle is bent to serve as a hook. I've had Kettle's since 1989 and never knew this.
But don't try it with the GBS center piece in place
