Unleash Osburn Matrix Wood Burning Insert [limited Qty] [u3RnBb5S]

The Matrix wood insert defines the new standards for contemporary look and performance. This fireplace insert looks like a sleek fireplace, but has all the advantages of an insert. Its faceplate and blower assembly were developed to allow a flush finish with the masonry fireplace. Cast iron was selected as the material of choice for this clean and modern unit. Installation into larger openings is facilitated by the use of an optional sheet metal backing plate. This insert will surely become the focal point of the room. The included surround for the Matrix wood insert measures 36.125" x 25.125". Optional Backing Plate Kits available for larger openings that require a larger surround.
