Harvia Chimney Clearances

WHP1500 and WHP1500M

Safety Distances

It is absolutely necessary to install the chimney according to these safety distance values. Neglecting them causes a risk of fire.

There shall be no inflammable materials within the established safety distances.
The safety distance between the inflammable structures and the chimney outer casing must be minimum 4 in.
If the connecting pipe in the forward end is of non-isolated material, the safety distance from this pipe to inflammable construction materials needs to be 15 in (WHP1500M) or 20 in (WHP1500).
The isolated chimney should be visible up to a minimum of 16 in.
When the fireplace is used a considerable heating takes place and the chimney needs to be protected with e.g. steel mesh in case it is exposed to touch. The protection, however, should not interfere with the ventilation around the pipe. There is no need for protection if the chimney is installed in a sauna.
Do not encapsulate the chimney.

Where can I find the manual?

What's the maximum temperature of the chimney?

According to the Harvia Manual, the maximum nominal chimney gas temperature of the furnace joint is 600 oC.

How wide is the chimney?

As per the Harvia Manual, the cross-section of the CHIMNEY is round and the diameter 8.7 in.

Note, the section directly above the sauna stove is called the smoke pipe.

The diameter of the smoke pipe is 4.5 in and it is made out of 0 in stainless steel.

How this is the chimney's metal?

The outer casing material is 0.5–0 in stainless steel (source: Harvia Manual)

What's the insulation material made out of?

The insulation material is mineral wool.

What's the maximum height of a Harvia chimney, and how far above the chimney can it extend?

The maximum height of the steel chimney is five meters while the permissible maximum for the self-supporting element (e.g. the element above the roof) is two meters.

Consult your local building department to confirm adherence, and to learn how far above the roof your chimney must extend.

Can the chimney be mounted at an angle?

The steel chimney can only be mounted in a vertical position.

Designing a Harvia Chimney System

Every part on this page belongs to Harvia’s modular WHP steel chimney system: a 4.5 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 4.5 in WZ smoke pipes (7.9 in, 19.7 in, or 1 m). 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 (20 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; 20 in (stainless) or 15 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.
