Placing of sauna stones

The placing of sauna stones has a major effect on the heater's safety and steam-creation properties.
Important information about sauna stones:
• Sauna stones should be rounded, with a diameter of 5–10 cm (e.g. R-991).
• 60 kg is a suitable amount. The amount of stones varies, depending on the type of stone.
• Only stones with a diameter of 5–10 cm are allowed.
• The stone surface may be rounded. The use of stones with a cleavage surface is not allowed.
• Suitable stone materials are peridotite, olivine diabase and olivine.
• Ceramic 'stones' and soft soapstone are not allowed. They do not absorb enough heat as the heater is being used.
Soft stones may crumble and block the air vents. This may break the heating elements and cause the product to
behave unlike it was designed.
• Rinse any stone dust off the stones before placing them in the heater.
How placing the stones, observe the following:
• Installation Images: 8.
• Start with the biggest stones, placing them at the bottom and sides. This ensures sufficient air ventilation and
forms a steady base for the stone space.
• Place the stones closely against the steel grid, and loosely at the top. Make sure the heating elements are not
visible between the stones. A dense layer will prevent direct heat radiation from overheating materials around the
heater. Pay particular attention to the corners where the heating elements are closest to the frame. Placing stones
loosely in the middle will allow air to flow through the heater, heating the sauna and sauna stones well.
• Place stones one by one. Do not drop them in the stone space.
• Do not wedge stones tightly between the heating elements. Make sure that the heating elements retain their
original position and shape despite the stones.
• Support the heating elements with stones so that they remain perpendicular to the heater.
• Do not place anything in heating element tunnel.
• Place the stones so that the weight of each stone rests on another stone, not on the heating elements.
• Do not pile a stack of stones on the heater. The stones may reach the level of the heater's air ducts. An excessive
amount of stones reduces ventilation and weakens the heater's properties.
• Before using the heater for the first time, make sure that the stones cannot fall off.
• We recommended that you keep some extra stones in store to replace broken ones or to add any if the stone level
becomes lower over time.
Do not place any items or devices in the stone space or its vicinity that can change the amount or
direction of air flowing through the heater.
If a heating element is not surrounded by stones, it can heat materials dangerously hot, even beyond
the heater's safety distances. Make sure that the heating elements are not visible beyond the stones.
As the user, you are responsible for ensuring that the stone space is properly maintained throughout
the heater's life cycle.
