The Superior WXS2021 is a freestanding, EPA-certified non-catalytic wood-burning stove from the Merit Series. It has a 2.0 cu. ft. firebrick-lined firebox that takes logs up to 19". Maximum output is 76,000 BTU/hr on cord wood, with maximum burn times of 7 to 9 hours on a full load.
The stove has a cast door with 5 mm ceramic glass and sits on a black pedestal base. An air wash sends a flow of air over the inside of the glass to slow build-up. Stainless secondary air tubes are part of the firebox.
It is a natural-draft stove with no electrical connection, so it keeps heating through a power outage. It needs a vertical 6" chimney. Superior rates it for 1,200 to 2,000 square feet as an approximation and designs it as a supplemental heater. An optional blower moves heat further into the room.
