    Overview

    Elegant faceplate, deep ash capacity

    The Matrix 1900 wears a cast iron faceplate with an upper louver and framed columns. A discreet black wooden handle, a removable-handle air control and the flush-mount blower blend in so that the detail of the faceplate stands out. The glass gives a broad view of the flames.

    The top and sides are tapered, which makes installation in smaller hearths easier, and the deep combustion chamber lets ash build up so you clean it less often. Logs up to 17" load over the width, and the minimum fireplace opening is 19" H x 25" W x 15 1/2" D.

    A door overlay is required to complete the insert. Installation must strictly follow the owner's manual. This model is EPA 2020 approved and is not approved for mobile home installation.
