Same WHP1500 steel chimney family, black powder-coated finish (WHP1500M). This dealer SKU is the two-box set: WHP1500M plus WHP-ASM angled-roof assembly. Match it to black Harvia wood stoves when the installer is using Harvia’s steel chimney, not a US Class A pipe.
How it is used

Code, UL, and who decides the flue
A licensed chimney installer and the authority having jurisdiction decide the flue for your building. We sell the manufacturer’s European steel chimney system named on this page. Harvia prints CE on the pages we cite. Those pages do not print a UL listing. We will not invent one. This is not a US 6-inch Class A kit.
Black WHP1500M is the same CE steel-chimney system as WHP1500, powder-coated black. Same 115 mm / 220 mm diameters. Not UL. Not 6-inch Class A.
Email hello@selfcaresaunas.com with roof type (flat vs pitched), ceiling height, and whether the stove loads from inside or through the wall — before you order pipe.
FAQ
Is this a US 6-inch Class A chimney?
No. Harvia’s WHP steel chimney is a European modular flue: inner smoke pipe 115 mm (about 4.53"), outer casing 220 mm (about 8.66"). Harvia.com prints CE. We do not invent UL. Your installer and local code decide whether this system is legal on your building.
Indoor house chimney?
Harvia’s own support page for WHP1500: suitable only for standalone outdoor sauna buildings — not as the chimney for a fireplace inside a house or vacation home. If the sauna is inside a dwelling, stop and email hello@selfcaresaunas.com.
Does the kit include a damper?
No. Harvia names WHP270SP (stainless) and WHP270SPM (black) as the matching dampers, sold separately.
Vertical only?
Harvia’s WHP steel chimney manual: vertical only. Total insulated height max 5.0 m with extensions. Indoor unsupported and outdoor self-supported heights are in that manual.
Pitched roof vs flat?
This US dealer SKU is the two-box set named WHP1500 + WHP-AS (angled-roof assembly) or the black WHP1500M + WHP-ASM pair. A symmetric/flat-roof assembly kit is a different SKU (WHPASSYM / WHPASSYMM). Confirm roof pitch with our team before the order leaves.
