That soapstone soaks up heat from the fire and gives it back gradually. It's finished in Matte Black, and its iron parts are made in HearthStone's own foundry in Spain.\u003c\/p\u003e\n\u003cp\u003eInside, HearthStone's TruHybrid system combines primary, secondary, and tertiary combustion with a catalytic combustor. HearthStone lists a weighted average efficiency of 78.5% (HHV), and the stove is EPA certified to the 2020 standard at 1.14 grams per hour. The 1.0 cubic foot firebox takes wood up to 18 inches long, and a 6 inch flue exits from the top.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the Green Mountain 20 Different\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoapstone-lined firebox.\u003c\/strong\u003e Soapstone absorbs the heat of the fire and releases it gently over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTruHybrid combustion.\u003c\/strong\u003e Primary, secondary, and tertiary combustion work together with a catalytic combustor in HearthStone's TruHybrid design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cast iron build.\u003c\/strong\u003e At 14.7 inches wide and 24.9 inches deep, it keeps a small footprint on the hearth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in HearthStone's foundry.\u003c\/strong\u003e The cast iron parts come from HearthStone's own foundry in Spain.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis listing is the HearthStone Green Mountain 20 TruHybrid wood stove, model 8620, in Matte Black (8620-0010).\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirebox volume:\u003c\/strong\u003e 1.0 cu ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum log length:\u003c\/strong\u003e 18 in (16 in recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlue size:\u003c\/strong\u003e 6 in, top exit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEPA-tested heat output (manual):\u003c\/strong\u003e 14,545 to 20,507 Btu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency (HHV):\u003c\/strong\u003e 78.5% weighted average\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEPA certified emissions:\u003c\/strong\u003e 1.14 g\/hr (EPA 2020 standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombustion:\u003c\/strong\u003e Catalytic (HearthStone TruHybrid)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Cast iron with soapstone-lined firebox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (H x W x D):\u003c\/strong\u003e 28 x 14.7 x 24.9 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 250 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety listings:\u003c\/strong\u003e UL 1482-2022, CAN\/ULC S627:2023\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eThe output range, efficiency, and emissions come from HearthStone's manual and EPA certification.
