The Harvia WL300PC chimney cover considerably reduces the required safety distances around the smoke pipe of a Cilindro wood-burning sauna stove. Crafted from premium steel with a chrome finish that matches the Cilindro’s styling, the cover is filled with sauna stones that absorb heat radiating from the chimney, shrinking clearances and opening up more placement possibilities in the sauna room.

Compatibility
Designed for Harvia Cilindro wood-burning sauna stoves and compatible with all Harvia steel chimneys, including the WHP1500 chimney kit. For Legend series stoves, use the Harvia WL300 smoke pipe cover instead.
Good to Know
How much does the WL300PC reduce safety distances?
Filled with stones, the cover absorbs radiant heat from the smoke pipe so the required clearance around the covered section is considerably reduced, the data sheet and installation instructions list the exact approved distances.
What stones should I use?
Harvia specifies 4–6″ (10–6 in) sauna stones, up to 41.9 lbs. Using the same stone type as your stove keeps the look consistent and the steam soft.
Does it fit the Legend series?
No, the WL300PC is shaped for the Cilindro’s round profile and chrome trim. Harvia’s WL300 cover is the equivalent for Legend stoves.
Designing a Harvia Chimney System
Every part on this page belongs to Harvia’s modular WHP steel chimney system: a 4.6 in (4.5″) smoke path inside a 8.7 in (8.6″) insulated casing, assembled with slot-and-lock joints. Here is how a complete system comes together:
- Start with the chimney. For pitched roofs, the WHP1500 kit (59.1 in chimney plus rain cap, tilted rain flange, smoke pipe, and ceiling lead-through set) is the core of the system. For flat roofs and barrel saunas, the WHP1000500 package bundles the chimney with the symmetric roof kit.
- Connect the stove. Bridge the stove collar to the insulated chimney with 4.6 in WZ smoke pipes (7.9 in, 19.7 in, or 3.3 ft). Add the WZ115030SP damper plate at the stove to control draft while firing, a WZ115120 reducer where pipe sections step down, or the WZ115155 adapter if you are transitioning to 6″ US Class A pipe.
- Reach your height. Add WHP500 (19.7 in) or WHP1000 (39.4 in) extensions. Stay within Harvia’s limits: 16.4 ft total chimney height, no more than 6.5 ft above the last support, lateral supports every 9.8 ft.
- Go through the roof. Choose the roof kit that matches your roofline: WHP-AS for tilted/pitched roofs, WHP-ASSYM for flat roofs and barrels. Replacement rain collars: WHM22 (tilted) and WHM24 (symmetric). Add a snow barrier above the chimney where sliding snow can load the flashing.
- Seal and control. The WHM25 vapor barrier restores the vapor-tight layer where the chimney passes the sauna ceiling; the WHP270 insulated damper closes the flue after the fire is fully out so the sauna holds its heat.
- Finish the stove side. Stone-filled covers (WL300 for Legend stoves, WL300PC for Cilindro) absorb radiant heat from the smoke pipe and significantly reduce its required safety distances.
Key clearances and rules: vertical installation only; 4 in (4″) from the insulated casing to combustibles; 19.7 in (stainless) or 14.8 in (black) from non-insulated smoke pipe unless shielded; designed for wood-burning stoves in standalone outdoor sauna buildings. Confirm your plan with your local building authority, and if you would like help speccing the system, talk to us; we design these daily.
