Depending on your unit, there are a few places the manufacturer information may be located. The first location would be a metal plate that is on the left or right side of the smoke shelf bracket, right at the top of the fireplace front opening. The next place would be just on the inside of the opening, behind the fireplace screens on the left or right side. The last location would be in the void space underneath the fireplace floor. This can be accessed either through the front of the unit's louvers or through a removable floor panel underneath the bottom refractory.If you do not have the manufacturer or model information of your fireplace, then we can offer universal replacement panels. We carry options for both wood-burning fireplaces and gas fireplaces. If you have a woodburning fireplace (or a fireplace that originally burned wood but now burns gas), we do offer some universal refractory panels that will work for your woodburning fireplace. Please see the following links:†One 24"h x 28"w Panel Two 24" h x 40"w Panels
These panels are about 3/4" thick and can be cut down to the size you need with a masonry blade or tile saw. They are suitable for use as side, rear, and floor panels inside any manufactured wood-burning fireplace.
