- The chimney is the part of a wood sauna that building inspectors and insurers actually care about.
- Confirm your stove's flue diameter and whether it connects top or rear before ordering.
- European flue sizes are metric — check whether you need the 4 in to 6 in adapter.
- A solid-fuel chimney usually needs a permit and an inspection in the US.
What does the Harvia Sauna Wood Stove Chimney Extension, 1000mm, Black Steel (WHP1000M) fit?
Harvia lists it for the Cilindro (Wood-Burning), Harvia 50, Legend, Linear, M Series and Pro series. These parts are size-specific — check your exact model against the list above, not just the series name.
Will this connect to a US chimney?
Harvia wood stoves use 115 mm (4.5 in) European flue pipe. A North American 6 in system needs the Harvia WZ115155 adapter. Confirm your flue diameter and whether the connection is top or rear before ordering.
Do I need a permit to install a sauna chimney?
In most US jurisdictions a solid-fuel appliance installation needs a permit and an inspection, and your insurer will usually want to see the sign-off. Check with your local building department before you order.
