Osburn

Matrix

This updated version of the Matrix wood insert will seduce you with an average particle emission rate as low as 1.54 g/h. The latest modifications made to this box are well in tune with the industry standards required for 2020. Although it retains a unique style that is both massive and sleek, we have reviewed the door mechanism to make it more functional. Adding a set of intermediate trim panels may be required to complete your masonry hearth. Always the same legendary Osburn quality. • Fuel type : Dry cordwood (16" recommended) • Recommended heating area-ft² : () 500 - 2,100 • Overall firebox volume-ft³ : 2.4 • EPA loading volume-ft³ : 2.02 • Maximum burn time : () 8 h • Maximum heat output-dry cordwood : (2) 75,000 BTU/h (22.0 kW) • Overall heat output rate < : (2) (3) 14,800 BTU/h (4.34 kW) to 28,600 BTU/h (8.38 kW) • Average overall efficiency (dry cordwood) : (3) 69 % (HHV) (4) 74 % (LHV) (5) • Optimum overall efficiency : (6) (7) 77 % • Optimum heat transfer efficiency : (8) 75 % • Average particulate emissions rate : (9) 1.54 g/h • Average CO : (10) 89.4 g/h
