Required Components to Complete the Stove
The Osburn 2000 OB02015 requires a door overlay and a base configuration. Choose a black or brushed-nickel door overlay and either a pedestal or compatible black/brushed-nickel cast-iron legs with ash pan kit. These required configuration components are not included.
High-Capacity Non-Catalytic Wood Heating
The Osburn 2000 combines a broad recommended heating range with a substantial firebox, long-log capacity, secondary combustion, and forced-air heat distribution.
Its non-catalytic combustion system works with a stainless-steel secondary-air system, refractory-brick-lined firebox, ceramic-glass viewing door, and air-wash system.
The included 130 CFM blower helps distribute heated air from the stove into the surrounding space.
EPA 2020 compliant: The supplied specifications list an average particulate emissions rate of 1.54 g/h.

Before You Order
Confirm Before Purchase
- You specifically need the Osburn 2000 OB02015.
- You have selected the required door overlay.
- You have selected a pedestal or compatible cast-iron leg package.
- Your installation can use the required 6" chimney system.
- Your chimney can meet the 12' minimum height requirement.
- You can maintain the required combustible clearances.
- You can provide the required floor protection.
- If installing in a mobile home, a compliant fresh-air intake will be used.
- You understand that heating and burn-time figures are performance ratings rather than guaranteed results in every home.
Do Not Assume
- That the door overlay is included.
- That the pedestal or leg package is included.
- That final stove height is identical with every base configuration.
- That 77% is the same as the average HHV or LHV efficiency rating.
- That the 75,000 BTU maximum output is the same as the tested overall heat-output range.
- That mobile-home installation is permitted without the required fresh-air intake.
- That alcove approval removes the need to follow clearances and floor-protection requirements.
