Osburn Matrix EPA 2020 Wood Stove with Blower
Up to 8 hours on one load. The Osburn Matrix (OB02032) is an EPA 2020-certified non-catalytic wood stove with a 2.4 cubic foot firebox rated up to 75,000 BTU/hr on dry cordwood at 79% optimum efficiency and 2.3 g/h, for 500 to 2,100 square feet. It takes 20-inch logs behind a wide 19-5/8" x 11-7/8" ceramic-glass view, stores firewood in its pedestal, vents through a 6-inch chimney, and ships with its 130 CFM variable-speed blower installed. It is approved for mobile-home and alcove installation. The side panels and the top panel complete it above and are priced on top; from $3,949 for the stove alone.
Choose the Matrix if you want a clean, modern stove that heats the main living area of a mid-size home and keeps its firewood close: logs stack in the pedestal right under the firebox. You finish it to suit the room — black-painted or soapstone side panels, and a black steel or two-piece soapstone top. The blower is already installed and its heat sensor starts and stops it by itself, the firebox takes 16-inch logs loaded east-west (20-inch at most), and one load runs up to 8 hours.
It is not right for a small room or a very large open house: the recommended range is 500 to 2,100 square feet. It is installed as a freestanding stove only, never in a factory-built fireplace, and in a mobile home it cannot go in a bedroom. In the United States it runs with the door closed; open-door burning with a fire screen is not permitted. It needs a 6-inch chimney at least 12 feet tall that serves no other appliance, 16 inches from a combustible side wall and 36 inches clear in front, and a non-combustible floor protector on any combustible floor.
Specifications
With a single-wall connector the Matrix sits 16 inches from a combustible side wall, 11 inches from the back wall and 10 inches from the walls in a corner (USA); a listed double-wall connector brings the back to 6 inches and the corner to 7 inches, with the side unchanged. Leave 36 inches clear in front and at least 84 inches from the floor to the ceiling. On a combustible floor, the non-combustible floor protector runs 16 inches in front of the door opening and 8 inches beyond each side of it. The chimney is 6 inches — a UL 103 HT factory-built chimney or a lined masonry chimney — at least 12 feet tall and 3 feet above the roof, reached through a 6-inch chimney connector. Lowered-ceiling, alcove and mobile-home layouts have their own clearance tables on pages 35 and 36 of the installation manual, and a certified heat shield or a wall shield can reduce clearances (see page 39).

Answers to common questions
What chimney does the Osburn Matrix need, and is any of it included?
None of the venting is in the box. The Matrix has a 6-inch flue collar on top and vents into a 6-inch factory-built chimney for solid fuel listed to UL 103 HT (2100 °F), or into a code-approved masonry chimney with a clay or listed stainless liner — an oversized masonry flue gets a listed 6-inch stainless liner. The chimney runs at least 12 feet, 3 feet above the roof and 2 feet above anything within 10 feet, and serves no other appliance. Between the stove and the chimney goes a 6-inch chimney connector: black-painted single-wall pipe at least 24 gauge in thickness, with no more than 10 feet of horizontal run and two 90° elbows, or a listed double-wall connector, which also cuts the clearances. The full venting rules are in section 9, starting on page 41 of the installation manual.
How close can it sit to a wall or in a corner?
In the USA, with a single-wall connector: 16 inches from a combustible side wall, 11 inches from the back wall and 10 inches from each wall in a corner. With a listed double-wall connector: 16 inches at the side, 6 inches at the back and 7 inches in a corner. Keep 36 inches clear in front and at least 84 inches from the floor to the ceiling. Lowered-ceiling, alcove and mobile-home layouts each have their own clearance table on pages 35 and 36 of the installation manual, and a certified heat shield or a properly built wall shield can reduce the clearances (page 39).

What goes on the floor under the stove?
On a combustible floor the stove needs a continuous non-combustible floor protector — sheet steel at least 0.015 inch thick or ceramic tiles sealed with grout, with a continuous non-combustible sheet under any tile — reaching 16 inches in front of the door opening and 8 inches beyond each side of it in the USA (18 inches in front and 8 inches at the sides and back in Canada), plus under any horizontal run of chimney connector with 2 inches to spare on each side. On a non-combustible floor such as concrete, no protector is needed.
What’s included, what’s required, and what’s optional?
-
Included in the box: The stove body with its cast-iron-framed door and 4 mm ceramic glass, firebrick lining, C-Cast baffle and four stainless secondary air tubes; Pedestal base with ash drawer and firewood storage underneath; 130 CFM variable-speed blower, installed, with HI-LO-OFF control and a heat sensor (thermodisc); EPA 2020 certification, UL 1482 / UL 737 / ULC S627 listing and the Osburn limited lifetime warranty.
-
Required to complete the installation, purchased separately: Side Panels - black-painted or soapstone panels that dress both sides of the stove; they go on before the stove is first used; Top Panel - a black steel panel or a two-piece soapstone top that finishes the top of the stove; Venting - a 6" listed factory-built chimney (UL 103 HT) or a lined masonry chimney, with a 6" chimney connector (see pg 41 in the installation manual); Floor Protection - on a combustible floor, a non-combustible protector 16 inches in front of the door opening and 8 inches beyond each side of it (USA), steel or grouted ceramic tile; Electrical - a 115 V outlet within reach of the blower's 8-foot cord, run so the cord never touches the stove or passes beneath it.
-
Optional: The outside-air parts — 5" air intake termination with clamps, airtight intake register and insulated flex pipe (a fresh air kit is required only in a mobile home), four floor protectors, and a rigid firescreen for open-door burning where it is permitted (not in the United States) — the stove burns wood fully without any of them.
Is the blower included, and does the stove need electricity?
Yes, the 130 CFM variable-speed blower is included and comes installed on the back of the stove, together with a heat sensor that starts it when the stove is hot and stops it when the stove cools down, so you can leave the HI-LO knob where you like it. It plugs into a standard 115 V outlet on an 8-foot cord — keep the cord off the stove and never run it underneath. The stove itself burns wood without power; only the blower needs it.
Can I store firewood in the pedestal?
Yes — the Matrix is certified for it. Stack the logs so they never reach past the inside edge of the pedestal, leave the heat shield under the firebox in place, and never lay anything combustible on that shield. The ash drawer sits above the storage space and the stove always runs with it closed.
Can it go in a mobile home or an alcove?
Yes to both. In a mobile or manufactured home it needs outdoor combustion air through an insulated duct from a ventilated crawl space or directly outside (never an attic, basement or garage), a double-wall connector only, a 6-inch double-wall factory-built chimney at least 12 feet long, and the stove anchored to the floor and secured to the structure; it never goes in a sleeping room. An alcove installation uses a double-wall connector and the alcove clearance table on page 36 of the installation manual.
How long does it burn, and what size wood does it take?
Up to 8 hours on a full load of dry cordwood, in Osburn's rating. The 2.4 ft³ firebox takes logs up to 20 inches, and 16-inch pieces loaded east-west — the long sides facing the glass — are what it is designed and EPA-tested for. Burn only seasoned wood at 15 to 20% moisture, never on a grate, and no wax or chemical logs; the warranty is void on anything but cordwood.
Does buying from The Torch Guys affect my Osburn warranty?
No. The Torch Guys is an authorized Osburn dealer, and Osburn's limited lifetime warranty runs through your dealer — if you ever need to claim, we deal with Osburn on your behalf. The combustion-chamber welds and the cast-iron door frame are covered for life on parts with 5 years of labour; the ceramic glass for life on parts; the pedestal, ash drawer, baffle and air tubes 7 years; the blower and its controls 2 years. It applies to the original purchaser, lifetime parts are replaced once, installation must be by a qualified technician, and it is void if anything but cordwood is burned. Keep your invoice and the serial number from the plate on the back.
