Osburn Matrix 1900 Wood Insert
Treat your family to incomparable comfort with the Osburn Matrix 1900 Wood Insert. Its magnificent cast-iron faceplate is adorned with a patterned upper louver and columns that frame its large door.
Its discreet black wooden handle, air control with removable handle as well as flush mount blower disappear to leave room for the delicate details of its faceplate. Osburn Matrix 1900 Wood Insert's large glass surface highlights a panoramic view of the flames to fully enjoy your moments near the fire.
The Osburn Matrix 1900 Wood Insert is a compact unit that has tapered top and sides for easy installation in smaller hearths. The deep bottom of its combustion chamber allows ash to accumulate and reduces the frequency of cleaning.

Will It Fit?
Measure your existing masonry fireplace opening before ordering. The Matrix 1900 needs at least:
| Minimum fireplace opening height |
19" |
| Minimum fireplace opening width |
25" |
| Minimum fireplace opening depth |
15 1/2" |
| Fireplace type |
Masonry only — factory-built fireplaces are not permitted |
| Chimney liner |
6" listed liner required, minimum 12' height |
Its tapered top and sides are what let it into hearths that won't take a squarer insert, so it's worth measuring even if a larger unit has already been ruled out.
