Forge & Flame Aspen C3

The Aspen C3 is rated for about 900–1,750 sq ft and is sized for cabins, small living rooms, and four-season porches rather than a whole large house. It has a compact 1.25 cu ft cast iron firebox with an EPA-tested output of 24,300 BTU per hour.

Its Continuous Combustion Control (C3) uses a heat-activated thermostat that closes the air shutter as the fire builds and opens it as the fire fades, with no electricity involved. Separate preheated secondary air burns the gases above the fuel bed. It's certified as a single burn rate heater and isn't approved for use with a flue damper.

A load burns about 7–10 hours, and the firebox takes logs up to 16 inches. Wood loads north-south, front to back, which makes refueling easier, and the manual recommends adding wood while the embers are still hot.

Yes. The cast iron top plate works as a cooking surface for a kettle or a pot of soup. You can also add the optional decorative ceramic glass cook top with the vintage logo.

With single wall pipe it needs 14 inches to a side wall, 8 inches to the back wall, and 6 inches in a corner; double wall pipe cuts the back and corner clearances to 3 inches. The floor protector extends 8 inches at the sides and rear, plus 16 inches in front in the US or 18 inches in front in Canada.

Yes, it's approved for mobile homes in the USA and Canada, but not in a sleeping room. The stove must be bolted to the floor and grounded to the frame with #8 copper wire, outside combustion air must be provided through its 3-inch inlet, and the chimney must be UL103 HT listed or use a full-length 6-inch UL-1777 liner.

Yes. The Aspen C3 is certified to the 2020 EPA particulate standard at 1.76 g/hr, with tested efficiency of 77% LHV and 71% HHV. It burns natural wood only, best when split and air-dried under cover for at least a year.

Check ash every day and remove it before it reaches the bottom of the door, typically every one to three days. Inspect the chimney connector every two weeks in heating season, check the door handle and leg bolts every two months, and do a spring cleaning of the gaskets, paint, and chimney each year.
