Osburn Matrix Wood Insert

The Matrix wood insert will seduce you with an average particle emission rate as 2.3 g/h and an optimal efficiency of 79%. 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.

Note that in order to install the optional projection kit AC01323, one of the optional faceplate backing plate kit AC01322 or AC01332 must be purchased separately to secure the projection kit to it.

(1) Values are based on test methods, except for recommended heating area, firebox volume, maximum burn time, and heat output.

(2) Maximum heat output (dry cordwood) is based on a loading density of 15-20 lb/ft³ and reloading intervals of 60-120 minutes. Other performance data assumes a fuel load of 7-12 lb/ft³ with 19-25% moisture content.

(3) As measured per CSA B415.1-10 stack loss method.

(4) Higher Heating Value of the fuel.

(5) Lower Heating Value of the fuel.

(6) Performance based on prescribed fuel load (7 lb/ft³, 19-25% moisture content).

(7) Optimum overall efficiency at a specific burn rate (LHV).

(8) Efficiency is optimized at a specific burn rate (LHV) and reflects the appliance's heat transfer efficiency at low burn rates.

(9) This appliance is tested and certified by an independent agency.
