JUUP Iivari

All three options share the same Iivari body, firebox and heating output. Differences come from structure, stone mass and the character of the löyly.

Kaski holds about 50 kg of stones. It heats the fastest and gives a traditional, lively löyly.

Punos holds about 75 kg of stones. It balances a reasonable heat-up time, good heat storage and a soft yet firm löyly.

Havu holds about 130 kg of stones. The larger stone mass heats more slowly, stores heat for longer and gives a deep, soft, lingering löyly.

First calculate the room volume:

width × depth × height

Then add one cubic metre for each uninsulated square metre of glass, brick, stone, tile or concrete. A glass door is included.

If every wall is uninsulated solid log, multiply the actual volume by 1.5.

Iivari is intended for saunas of 9–18 m³ calculated volume. Near 18 m³ it is already at the upper end of its range. For a conservative choice, especially in a cold outdoor sauna, we recommend the next size, Gösta.

Iivari has a 115 mm outer-diameter flue connection. The stove can be connected from the top or the rear.

The flue temperature class must be at least T600, and the stove must not be connected to a shared flue. A matching flue set can be supplied separately. The final flue solution and penetrations must follow the site, the flue manufacturer’s instructions and local regulations.

In a correctly sized, well-working sauna the reference time to about 60 °C is 30–45 minutes. Actual time depends on starting temperature, construction, ventilation, draught, dryness of firewood and chosen stone mass.

Kaski heats the fastest. Punos needs a little more time, and Havu with its large stone mass heats the slowest but holds heat the longest.

As a rule of thumb, the Iivari stone bowl is usually ready for löyly after the first load of wood, even if the room has not yet reached the desired temperature.

If heating takes clearly longer than usual, check draught, replacement air, firewood dryness and ash and soot.

Without separate protection, minimum distances to combustible materials are 200 mm at the sides and rear, 300 mm in front and 1100 mm above.

JUUP protective walls halve the side and rear safety distances measured from the stove. Front and ceiling distances do not change.

Final installation must always follow the stove and flue instructions and local fire regulations.

Iivari has a five-year warranty in private use and a one-year warranty in other use.

The warranty covers the stove structure, including the stone surround, and burn-through and rust-through when the stove is used, maintained and swept according to the instructions.

Yes. A 20-litre water heater can be fitted to the side of Iivari Kaski and Punos. It does not fit Havu, because the stone surround around the stove takes the space the heater needs.

Depending on use, the water typically reaches about 60–65 °C in around one hour.

The standard delivery includes the chosen Iivari stove, glass door, chosen handles, and user and installation instructions. The stove is prepared for both top and rear flue connection.

Sauna stones, flue, a separate flue pipe or adapter, stove base, protective walls, water heater and transport are not included unless agreed in the order confirmation.

We recommend dark vulcanite stones. Peridotite, olivine diabase and olivine stones intended for wood-burning sauna stoves are also suitable.

Ceramic stones can be used, but they heat and release heat faster than natural stone. For a mass that stores heat longer and a firm löyly, we recommend natural stones.

Place large stones about 10–15 cm in diameter at the bottom of the kivipesä and stone surround. Fill the top loosely with smaller stones so air can circulate and metal parts are covered. Rinse stones before use.

The amount depends on shape and stacking. Indicative masses are about 50 kg for Kaski, 75 kg for Punos and 130 kg for Havu. We recommend about 10 kg extra. As stones are usually sold in 20 kg packs, this often happens automatically.

Yes. Iivari is available as a through-wall fireplace stove heated from outside the sauna room.

The wall-through part is sized as standard for about 230 mm wall thickness, and can be shortened to suit the site. Wall construction, thickness and fire protection must be checked before ordering.

Contact us or your nearest dealer if you are interested in the through-wall version.

Empty the ash pan before heating and check regularly that ash or soot has not built up in the smoke channels or around the kivimalja.

Check and restack stones at least once a year. Remove broken stones and grit so air can circulate. The flue and connecting pipes should be swept regularly.

Cooled metal surfaces can be wiped with a damp, soft cloth. If needed, use a mild cleaner suitable for painted metal. Avoid abrasives and strong oven or grill cleaners. Rinse cleaner off with clean water before the next use.
