{"product_id":"huum-cage-hstv","title":"HUUM Cage HSTV Stone Cage for HIVE Wood Stoves","description":"\u003cp\u003eThis cage sits on a HUUM wood stove around the flue and you fill it with extra stones. The stove’s own pile is not enough. Heat from the pipe goes into the rocks instead of sitting on bare metal. It is a stone cage, not a chimney set, not a rain cap, and not an embedding flange.\u003c\/p\u003e\u003ch3\u003eHow it is used\u003c\/h3\u003e\u003cp\u003eSet it on the stove around the chimney pipe, then fill. HUUM’s US stone-cage manual: 35–40 kg \/ 77–88 lb of 5–10 cm (2–4 in) stones in the cage. We shop the upper end — about 40 kg \/ 88 lb — as about 3 extra boxes of HUUM SM (534-BDL-STONES-SM-33, 15 kg each → 45 kg vs 40 kg spec). Not Harvia 10–15 cm. Stones sold separately. Cages stack; HUUM’s US sheet says you can put more than one on a flue (M6 bolts, 14 mm thread, sold separately — not in this carton). Fits HIVE Wood 13 \/ 17 \/ LS 17 and HIVE Flow \/ Flow LS \/ Mini \/ Mini LS. Not for HUUM electric DROP, HIVE, CLIFF, or STEEL. Not an embedding flange (those are different SKUs).\u003c\/p\u003e\u003ch3\u003eWhat’s included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHUUM Cage HSTV stainless stone cage (model CAGE HSTV \/ H3009042)\u003c\/li\u003e\n\u003cli\u003eUS install sheet (linked below)\u003c\/li\u003e\n\u003cli\u003eStones not included — budget about 3 extra 15 kg boxes of 5–10 cm HUUM SM per cage\u003c\/li\u003e\n\u003cli\u003eStacking bolts \/ nuts not included\u003c\/li\u003e\n\u003cli\u003eChimney set not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e HUUM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e CAGE HSTV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 534-HIVE-STV-STCAGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer code:\u003c\/strong\u003e H3009042\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e All HUUM wood-burning stoves in this shop: HIVE Wood 13 \/ 17 \/ LS 17; HIVE Flow \/ Flow LS \/ Mini \/ Mini LS (and those packages)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot for:\u003c\/strong\u003e HUUM electric (DROP \/ HIVE \/ CLIFF \/ STEEL); embedding flanges; Harvia \/ Cozy stoves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial (HUUM):\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight (HUUM):\u003c\/strong\u003e 43 cm \/ 16.9 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter (HUUM):\u003c\/strong\u003e 30 cm \/ 11.8 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone size in the cage (HUUM US manual):\u003c\/strong\u003e 5–10 cm \/ 2–4 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone amount in the cage (HUUM US manual):\u003c\/strong\u003e 35–40 kg \/ 77–88 lb — on top of the stove’s own stones\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtra boxes (this shop):\u003c\/strong\u003e About 3 extra boxes of 534-BDL-STONES-SM-33 per cage (15 kg each → 45 kg vs 40 kg spec)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStacking:\u003c\/strong\u003e Yes — more than one cage per flue; hardware not in the carton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRole:\u003c\/strong\u003e Smoke-pipe stone cage — not the flue\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/huumsauna.com\/wp-content\/uploads\/2025\/11\/huum-stone-cage-manual-us.pdf\" target=\"_blank\" rel=\"noopener\"\u003eHUUM HIVE stone cage US manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDo I still need the stove’s own stones?\u003c\/strong\u003e\u003cbr\u003eYes.
