The Osburn Matrix 1900 Wood Burning Insert is a combination of elegance and efficiency. The cast iron surround has a beautiful pattern with upper louvers and side columns that elegantly frame the large viewing door. The surround will cover any fireplace less than 23.875″ tall by 36″ wide. A 33″ tall by 44″ cuttable flashing is available for large fireplaces. The large glass surface allows you to enjoy the time spent next to the fire. The flush mount blower is hidden from within the insert accentuating the details of the fireplace.
The Osburn Matrix 1900 insert is a smaller more compact version of the Matrix series and is able to be installed in smaller hearths. The minimum fireplace opening for the Matrix 1900 insert is 19″ tall x 25″ width x 15.5″ depth. The sides and the top are tapered to easily slide in a smaller fireplace. The 1.03 cubic foot fireplace box can handle up to a 17″ log. However, a 16″ log is recommended for the Matrix 1900 and has a max burn time of up to 7 hours, producing up to 45,000 BTUs with a heating area of up to 1,200 square feet.

The Osburn Matrix 1900 fireplace insert has one additional option for the Faceplate size. The 32″ x 44″ Cuttable Faceplate is available for fireplaces that are larger than 23.875″ x 36″. The Cuttable Faceplate easily attaches to the back of the included Faceplate to cover any gaps on large fireplaces. You can cut the top edge and sides of the Cuttable Faceplate to contour an arched fireplace or to minimize the amount of flashing you will see. The Cuttable 32″ x 44″ Faceplate is the perfect solution for larger fireplaces.
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 the 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 Rigid Firescreen 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 and relax by the fire on a cold winter’s night. The Rigid Firescreen 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 Firescreen.
Rock-Flex 316Ti stainless steel chimney liner kits are UL listed and the perfect choice to install for your new wood burning insert. Each kit includes the 316Ti Flexible Chimney Liner, Vertical Appliance Connector, 13 x 13 in. Premium Top Plate, and Round Rain Cap.

Hands down the best experience we’ve had with a company doing work on our home. We found them through an internet search, looking for quotes for a complete chimney overhaul. From the first phone call to the day, they completed the work, everyone we talked to was professional, knowledgeable, and friendly! Yup, they were all nice people! We noticed a small issue after they were finished. Within 24 hours, the owner had been out to look at it and a technician was sent out to correct the problem. And they were, again, nice, and completely understanding about it. We couldn’t be happier with the result. We highly recommend ACS to everyone!
We had to have a rebuild done on our chimney. They were very professional and worked hard. What a wonderful job they did! They took away all the old bricks and cleaned them up after they were done. Our chimney looks fantastic. The pricing was very affordable. Thank you, Affordable Chimney!
Brandon, the Affordable Chimney Sweeps technician, inspected my chimney and found a dangerous problem that had been missed by another company’s inspector. As a result, I contracted to have Affordable replace the chimney liners and do other repairs to both the fireplace and heating exhaust systems. Their quoted price was 20% lower than the others. The estimated time for the work was 2.5 days. They came in on time and worked hard without breaks until the rain started late in the afternoon. They came back the next day and surprisingly finished in a couple of hours. They worked hard, they were courteous, and they answered all my questions. They cleaned up carefully. They earned their 5 stars.
