6.6. Placing of sauna stones

Sauna heater stones are important for the safety of the sauna heater. In order for the
warranty to remain valid, the user is responsible for proper maintenance of the stone
space in accordance with the specifications and instructions.
Do not place any items or devices in the sauna heater's stone space or vicinity that can
change the amount or direction of air flowing through the sauna heater.
If a heating element is not surrounded by stones, it can heat materials dangerously
hot, even beyond the sauna heater's safety distances. Make sure that the heating ele-
ments are not visible beyond the stones. As the user, you are responsible for ensuring
that the stone space is properly maintained throughout the sauna heater's life cycle.
Important information on suitable sauna stones:
• Suitable sauna stone materials are peridotite, olivine diabase, olivine and vulcanite.
• Only use cleavage surface and/or rounded stones for your sauna heater.
• If the heating elements of an electric sauna heater are in contact with the stones, rounded stones
may only be used in the outer layers of the stone space, so that they do not come into contact with
the heating elements.
• Ceramic stones and decorative stones may only be used if they have been approved by the manufac-
turer and are used according to the their instructions.
• Note that decorative stones are only suitable on the top layer of the stone space. Decorative stones
must be placed loosely to ensure sufficient air circulation. Place any decorative stones so that they do
not touch the heating elements of an electric sauna heater.
• The warranty does not cover any defects that have been caused by the use of decorative stones or by
sauna stones not recommended by the manufacturer.
• Rinse any stone dust off the stones before placing them in the heater.
How placing the stones, observe the following:
• Start with the biggest stones, placing them at the bottom and sides. This ensures sufficient air venti-
lation and forms a steady base for the stone space.
• Place stones one by one. Do not drop them in the stone space.
• 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.
• 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.
