Overview
The new standard lowering the fine particulate emission threshold will be conquered by the recent certification of the Osburn 2000 wood burning stove. This revamped version now offers a particulate emissions rate of 2.3 g/h, a maximum heat output of 75,000 BTU/h and 79% optimum efficiency. This insert still has a 2.4 ft3combustion chamber and a 144-CFM variable speed fan that is strategically positioned to redistribute heat throughout the room.
Designed to receive an optional faceplate that can cover a masonry hearth up to 32 inches (81 cm) high and 50 inches (127 cm) wide. A steel door overlay is available in black or brushed nickel as well as faceplate trims. Look no further, treat yourself to Osburn's legendary quality!
