To attach the grates to their hinges, insert the grate slot over the hinge pin on the side of the cooktop. Be sure to keep the grate angled above the cooktop to avoid scratching the cooktop until the grate is seated on the hinge pin. Then position the grate down onto the cooktop. A B A. Grate slot B. Hinge pin Although the burner grates are durable, they will gradually lose their shine and/or discolor due to the high temperatures of the gas flame.

Ideal cookware should have a flat bottom, straight sides and a well-fitting lid, and the material should be of medium-to-heavy thickness. Rough finishes may scratch the cooktop or grates. Aluminum and copper may be used as a core or base in cookware. However, when used as a base they can leave permanent marks on the grates. Cookware material is a factor in how quickly and evenly heat is transferred, which affects cooking results. A nonstick finish has the same characteristics as its base material. For example, aluminum cookware with a nonstick finish will take on the properties of aluminum. Cookware with nonstick surfaces should not be used under the broiler. Check for flatness by placing the straight edge of a ruler across the bottom of the cookware. While you rotate the ruler, no space or light should be visible between it and the cookware. 1 2 3 1 4 5 6 2 7 8 3 9 1 0 1 1 4 1 2 1 3 5 1 4 1 5 1 6 6 1 7 1 8 7 1 9 2 0 Use the following chart as a guide for cookware material characteristics.
