1.1. Piling of the Sauna Stones

The piling of the sauna stones has a great effect
on both the safety and the heating capability of the
heater.
Important information on sauna stones:
The stones should be 2-4'' (5–10 cm) in
•
diameter.
Use solely angular split-face sauna stones that
•
are intended for use in a heater. Peridotite,
olivine-dolerite and olivine are suitable stone
types.
Neither light, porous ceramic "stones" nor soft
•
soapstones should be used in the heater. They
do not absorb enough heat when warmed up.
This can result in damage to heating elements.
Wash off dust from the stones before piling
•
them into the heater.
Please note when placing the stones:
The aim is to pile a dense layer of stones
•
against the steel enclosure and pile the rest of
the stones loosely. The dense layer prevents
the direct heat radiation from overheating
materials around the heater. The loose piling of
stones in the middle lets the air flow through
the heater, resulting in good heating of sauna
and sauna stones.
Do not drop stones into the heater.
•
Do not wedge stones between the heating
•
elements.
Pile the stones so that they support each other
•
instead of lying their weight on the heating
elements.
Support the heating elements with stones so
•
that the elements stay vertically straight.
Do not form a high pile of stones on top of the
•
heater.
No such objects or devices should be placed
•
inside the heater stone space or near the heater

distances. Check that no heating elements can be
seen behind the stones.

1.1.1. Maintenance

Due to large variation in temperature, the sauna
stones disintegrate in use.
Rearrange the stones at least once a year or even
more often if the sauna is in frequent use. At the
same time, remove any pieces of stones from the
bottom of the heater and replace any disintegrated
stones with new ones. By doing this, the heating
capability of the heater stays optimal and the risk
of overheating is avoided.
elements do not appear with time. The stones settle
most rapidly within the first two months of piling.

1.2. Heating of the Sauna

When operating the heater for the first time, both the
heater and the stones emit smell. To remove the smell,
the sauna room needs to be efficiently ventilated.
If the heater output is suitable for the sauna room,
it will take about an hour for a properly insulated
sauna to reach the required bathing temperature (
2.3.). The sauna stones normally reach the bathing
temperature at the same time as the sauna room.
A suitable temperature for the sauna room is about
149–167 °F (65–75 °C).
or inside the given safety distance.
that could change the amount or direction of
the air flowing through the heater.
A bare heating element can endanger
combustible materials even outside the safety
Pay attention especially to the gradual settling
of the stones. Be sure that the heating

that there isn't anything on top of the heater
