I just purchased a new Char-Broil gas grill today. It came with a manual, which I read before doing anything else. What puzzles me are two unidentified parts that are not mentioned in the product manual. Does anyone know what these two parts are called and what their purpose is?  Photo #1: Small metal item that came in bag with manual.    Photo #2: Metal piece hanging by chain from left side of grill.    Here it the item in better context.   
I had similar issues with a horrible chemical smell no matter what brand I purchased.  A friend suggested fresh baked as an alternative. Really simple and it solved my issues.
