Are you talking about the side burner or the grate inside your BBQ? I light mine with the side burner, but if I were to light charcoal inside my gasser, I would take out the grate and the flavor bar(s) and set the chimney directly on the burner. It's probably wise not to load up the chimney, the weight might harm the burner, probably best to do two or more 1/2 loads vs 1 full load
