Osburn Matrix 2700 Fireplace Insert This updated version of the Matrix 2700 runs at an average particulate emission rate of just 1.2 g/h — the cleanest-burning appliance in the Osburn insert range and comfortably inside the EPA 2020 standard. The latest modifications made to this box are well in tune with the industry standards required for 2020. Although it retains a unique style that is both massive and sleek, we have reviewed the door mechanism to make it more functional. Adding a set of intermediate trim panels may be required to complete your masonry hearth. Always the same legendary Osburn quality. Inspired by nature, the Matrix 2700 insert is a fusion of traditional style and technological innovation. Located in the heart of your living space, the generous viewing area of the Matrix 2700 will invite you to sit back, relax and take in the calm and warmth of its flames.
