Warning: A wood burning insert belongs inside a masonry fireplace only. Never install one in a combustible structure or a wooden fireplace enclosure. The existing masonry hearth must be intact and functional.

An old insert that struggles to meet modern emissions standards is a problem. The Matrix wood insert solves that with an average particle emission rate of 2.3 grams per hour and optimal efficiency of 79 percent. The latest modifications meet industry standards required for 2020.

Although this unit retains a unique style that is both massive and sleek, the door mechanism has been reviewed to make it more functional. Adding a set of intermediate trim panels may be required to complete a masonry hearth. But that is a small price for legendary Osburn quality.

This modern fireplace insert and fireplace insert (generic) fits where others cannot. Technical confidence from the updated design and clean emissions. Lifestyle comfort means a warm room with a beautiful fire, without worrying about pollution or efficiency.
