If the grill is to be placed into a combustible enclosure, it's a must that an approved insulated jacket is necessary. Use only the DCS insulated jacket which has been specifically designed and tested for this purpose.
DCS Insulated Jackets are completely constructed of stainless steel and are recommended for combustible island installation. Insulated jackets must be supported from bottom. The BGB30-IJS is for use with DCS 36-inch built-in grills.
