Zero Clearance Wood Stove Insert · Up to 28,900 BTU · Heats 800-1,800 sq ft
The Buck Stove Model 21ZC is a zero clearance wood burning stove built for new construction or a remodel where a masonry fireplace is not in the budget. It is a non-catalytic design that suits zone heating and smaller spaces.
The 21ZC is rated 11,079 to 28,900 BTUs per hour and heats roughly 800 to 1,800 square feet, which makes it a good fit for a vacation cabin or a smaller house. Its zero clearance construction lets you frame it into a wall instead of building a masonry chimney structure.
It is a non-catalytic stove with a 1.6 cubic foot firebox, rated at up to 70% efficiency and 1.7 g/h emissions. Logs up to 11" front to back fit inside, the flue is 6", and the stove is approved for prefab and mobile homes.
Pick a Black, Gold or Pewter door, and choose between no trim kit, a standard trim kit or an oversize trim kit. A blower is optional. Buck Stove makes this model in Spruce Pine, North Carolina using precision laser cutting.
