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. Eco-savvy consumers will appreciate its efficient combustion, quality performance and classic beauty. Customize the look of this non-catalytic appliance by choosing from a black or brushed silver-plated door overlay and fire screen.

Will It Fit?
Measure your existing masonry fireplace opening before ordering. The Matrix 2700 needs at least:
| Minimum fireplace opening height |
27 1/8" |
| Minimum fireplace opening width |
31 3/4" |
| Minimum fireplace opening depth |
22 1/8" |
| Fireplace type |
Masonry |
| Chimney liner |
6" listed liner required, minimum 12' height |
This is the largest hearth requirement in the Osburn insert range. If your opening is smaller, the 2000-I or Inspire 2000-I cover most of the same heating range from a smaller firebox.
