Converting your Char-Broil gas grill to natural gas has a lot of benefits— it’s better for the environment, costs less and, most importantly— you’ll never run out fuel in the middle of a big cookout. Our BBQ natural gas conversion kit converts your grill from propane to natural gas. Refer to your grill's rating label for appropriate conversion kit details. This kit is compatible with Kenmore grill models: 23665 and 23666.
