The Matrix wood insert defines the new standards for contemporary look and performance. This fireplace insert looks like a sleek fireplace, but has all the advantages of an insert. Its faceplate and blower assembly were developed to allow a flush finish with the masonry fireplace. Cast iron was selected as the material of choice for this clean and modern unit. Installation into larger openings is facilitated by the use of an optional sheet metal backing plate. This insert will surely become the focal point of the room.

The included surround for the Matrix wood insert measures 36.125" x 25.125". Optional Backing Plate Kits available for larger openings that require a larger surround.

Optional Accessory Details

Fresh Air Kit - 5 in. Diameter Oval

The 5" Fresh Air Oval Kit is required if you plan on connecting a fresh air intake pipe. The oval adapter kit comes with the oval adapter, 2 clamps and the fresh air intake register hood. The oval adapter is intended for 5" fresh air intake pipe. You will have to manually ovalize the flexible intake pipe to make the connection to the adapter. The oval adapter can be positioned on either side of the fireplace insert.

The 5" Fresh Air Intake Register with Airtight Damper opens and closes the fresh air supply to a wood stove insert. It's simple mechanism makes it possible to close the damper tightly when the wood stove insert is not in use. This will ensure the wood stove insert is not being cooled while the stove is not in use. Fresh Air Intake with Damper Installation Guide

Rigid Fire Screen

The Rigid Fire Screen allows you to burn wood in the wood insert with the door open just like an old-time fireplace. Hear the crackle of the wood, watch the flames dance around in the firebox and relax around the wood insert on a cold winter's night. The Rigid Fire Screen is easy to install and easy to remove when you are ready to load more wood. The insert should not be burning with the door open without the Fire Screen.

Bottom Faceplate Backing Plate

In the event the current fireplace is elevated above the hearth, then the Faceplate Backing Plate Kit is installed. The Bottom Faceplate Backing Plate is used to finish off this type of installation. This backing plate will provide the look of a picture frame around the insert. The Bottom Faceplate Backing Plate is available in both 44" x 6" and 50" x 6" sizes. Bottom Faceplate Backing Plate Installation Guide

Faceplate Backing Plate Kit

The Faceplate Backing Plate is used when the standard flashing for the Osburn Matrix is not large enough to cover the opening of the fireplace. The standard Matrix surround measures 36.125" x 25.125". The Faceplate Backing Plate can be used to extend the surround to seal off the fireplace. The Backing Plate is available in two sizes: 44" x 29" and 50" x 29". The Projection Kit can be used in conjunction with the Faceplate Backing Plate Kit. The backing plate easily installs to the back of the standard surround. Faceplate Backing Plate Kit Installation Guide

Projection Kit For Insert - 2 in. or 4 in.

The Projection Kit for the Osburn Matrix fireplace insert is the perfect solution if your fireplace depth is not large enough to fully push the insert into the fireplace opening.

All of the required hardware is included. Projection Kit Installation Guide
