Osburn Matrix 2700 Wood Insert with Blower | OB02700

Osburn Matrix 2700 Wood Insert with Blower | Model OB02700

The Osburn Matrix 2700 OB02700 turns an existing masonry fireplace into a serious supplemental heater while retaining the visual presence of a large hearth. A cast iron faceplate frames the generous glass door, giving the insert a more architectural, traditional look than a plain steel fireplace opening.

Its non-catalytic 2.5-cubic-foot firebox handles regular wood heating, and a heat-activated blower is included to move warmth into the room. Black or brushed-metal door overlay options and an optional firescreen make the unit easier to coordinate with a fireplace renovation. The design is especially useful when you want to improve heat delivery without giving up a familiar masonry hearth.

Who Is the Matrix 2700 Insert Designed For?

The Matrix 2700 is a choice for homeowners with a sizeable existing masonry fireplace who want a cast iron-fronted insert with a pronounced hearth presence. Compared with the smaller Matrix 1900, its 2.5-cubic-foot firebox offers more space for cordwood and a higher manufacturer-recommended heating range of 750 to 2,200 square feet. The generous glass and included heat-activated blower are particularly useful when a fireplace is being upgraded primarily to provide controllable heat rather than occasional ambiance.

Measure the masonry firebox at several points, not just the visible front opening. Osburn lists minimum fireplace-opening measurements for the Matrix 2700, and the actual liner route, damper area, hearth projection and mantel clearances must also be checked. The cast iron faceplate is included, while door overlay and firescreen choices should be confirmed against the offered configuration. This insert is not suitable for a combustible framed wall opening, and the existing chimney normally needs a properly specified listed 6-inch liner.

• Cast iron faceplate supplied as standard

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 wood insert is intended for a suitable existing masonry fireplace, not installation inside a combustible wall or factory-built enclosure. Verify masonry opening dimensions and the required listed 6-inch chimney liner before purchase.

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

Does the Matrix 2700 come with a blower?

Yes. Osburn specifies a heat-activated 176 CFM blower. This helps move heat into the room, although a blower does not eliminate the need for a correctly sized stove and chimney system.

Can the Matrix 2700 go in a zero-clearance fireplace?

Do not assume so. Osburn identifies this as an insert for an approved existing masonry fireplace. Check the current installation manual and the fireplace's construction before ordering.

Is the Matrix 2700 larger than the Matrix-I?

Its 2.5-cubic-foot firebox is slightly larger than the Matrix-I's 2.4-cubic-foot firebox, and the models use different front designs and minimum masonry openings. Compare measured fit as well as appearance.
