WHP chimney clearance
100 mm insulated chimney to combustibles; 500 mm single-wall pipe to walls (stainless; 375 mm with the black WHP1500M connector)
The insulated chimney runs 220 mm outside diameter over the 115 mm smoke pipe. Keep at least 430 mm of insulated chimney visible in the room. Lead-through insulation must be class A or long-term rated at 750 C or more (Harvia ZSH-200 in the kit).
WHP chimney scope
Vertical roof-pass installs only; standalone outdoor sauna buildings per Harvia support (2026)
For an indoor or residential build, the installer specifies a listed North American chimney path (e.g. UL 103 HT Class A via a 115 mm to 6" adapter) with AHJ sign-off instead of the WHP kit. Harvia 115 mm smoke pipes and WHP chimneys fit all Harvia wood-heated sauna stoves except the Harvia 50, plus the Harvia 10 iron stove.
WHP chimney limits
5 m max chimney elements; 2 m max freestanding element; 3 m max indoor lateral-support spacing
- Go-to wood stove family for SaunaDesignPro wood-burning sauna plans
- T600 chimney required; Harvia manuals list 115 mm connection opening and 110 mm minimum flue inner diameter
- Use Harvia WHP steel chimney kit/extensions/damper or an AHJ-approved equivalent specified by the installer
- Harvia WHP steel chimney installs vertically through the roof only, and Harvia support (2026) specifies it for standalone outdoor sauna buildings - indoor or residential builds need an installer-specified listed chimney path (e.g. UL 103 HT Class A)
- Harvia WHP steel chimney manual lists 100 mm minimum clearance from combustibles to the insulated outer casing; the non-insulated connecting pipe needs 500 mm (stainless WHP1500) or 375 mm (black WHP1500M), with at least 430 mm of insulated chimney left visible
- Align the roof and ceiling lead-through holes to the actual top flue collar, not the center of the rectangular stove footprint
- Harvia Legend smoke-pipe drawing places the Legend 150 top connection center 180±5 mm from the back edge
- Non-combustible base, heat shields, roof/ceiling lead-through, combustion air, and local fire-code review required
- Safety distances apply only with stones placed per the Harvia manual
- Legend 150 standard safety drawing: 200 mm combustible side clearance, 250 mm rear clearance, 500 mm front clearance, and 1000 mm top clearance.
- Legend 150 SL uses the through-wall firebox extension; coordinate non-combustible opening details and adjacent-room clearances.
- SL feeds through the wall: concrete/brick opening min 220 mm wide, min 390 mm high from the floor, wall max 150 mm thick (manual 292 Fig 13). The 200 mm extension leaves ~50 mm of door proud of the thickest allowed wall.
