Osburn Matrix Wood Insert w/ Blower | OB02028

Osburn Matrix Wood Insert with Blower | Model OB02028

The Osburn Matrix OB02028 is designed for masonry fireplaces that need more useful heat without giving up a dramatic, contemporary hearth appearance. A sculpted cast iron faceplate and wide glass door make the fire the centerpiece, while the flush-fit insert takes advantage of an existing fireplace location.

Behind the clean design is a 2.4-cubic-foot non-catalytic firebox, glass air-wash system and an included convection blower. Different backing panels and an optional projection kit can help finish certain fireplace openings, subject to the manufacturer's compatibility requirements. This is a strong choice when a masonry fireplace remodel needs both modern styling and functional wood heat.

When to Choose the Matrix-I Wood Insert

The Matrix-I is for the homeowner who likes a bold contemporary cast iron fireplace front but wants to keep an existing masonry chimney and hearth. Its 2.4-cubic-foot firebox sits in the popular mid-size insert class, and Osburn recommends the unit for roughly 500 to 2,100 square feet under appropriate conditions. A blower is included, making the model a practical alternative to a decorative open fireplace that sends much of its heat up the chimney. The main distinction from the traditional Osburn 2000-I is visual: the Matrix puts the surround and wide glass viewing area at the center of the design.

Check both the insert body and the decorative faceplate against the actual masonry opening. The manufacturer offers backing plates and a projection kit for select installations, but a particular combination may require additional components. Document opening width, height and depth, hearth extension and the existing chimney before ordering. A listed 6-inch liner and compliance with the manufacturer's clearance instructions remain essential regardless of how cleanly the cast iron face fits the visible fireplace opening.

Manufacturer figures are reference values, not guaranteed heating results. Maximum BTU output, tested output rates and burn-time estimates use different conditions; real performance depends on fuel quality, chimney draft, climate, home heat loss and operating settings. Confirm all dimensions and listed installation clearances in the current manual before ordering.

Installation and Compatibility

This model is for installation into an approved existing masonry fireplace with a listed chimney liner. Match the faceplate/backing accessories and 6-inch liner to your opening dimensions; some projection-kit configurations require another separately purchased component.

Important: Wood-burning inserts must be installed only in a compatible existing masonry fireplace, in accordance with the manufacturer's listing and installation instructions.

Frequently Asked Questions

What is the difference between the Matrix-I and Matrix wood stove?

Matrix-I OB02028 is installed in a compatible masonry fireplace. The Matrix stove OB02032 stands on the floor as a freestanding heater and has different dimensional and clearance requirements.

Is the blower included with the Matrix-I?

Yes. Osburn lists a 90 CFM blower. Check the selected product package for any separate surround or finishing accessories needed for your specific hearth.

Will the faceplate cover my fireplace opening?

That depends on your masonry dimensions and selected backing or projection accessories. Compare the complete finished-face dimensions with your opening rather than looking only at the stove's firebox measurements.
