1.1. Piling of the Sauna Stones

The piling of the sauna stones has a great effect on
the functioning of the heater (figure 1).
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:
Do not drop stones into the heater.
•
Place the stones sparsely to ensure that air can
•
circulate between them.

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
149–176 °F (65–80 °C).
Before switching the heater on always check
that there isn't anything on top of the heater
or inside the given safety distance.

1.2.1. Using the Heater

Heater is controlled from a separate control unit.
See the instructions for use of the selected control
unit model.

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 piec-
es of stones from the bottom of the heater and re-
place any disintegrated stones with new ones. By
doing this, the heating capability of the heater stays
optimal and the risk of overheating is avoided.
ments do not appear with time. The stones settle
most rapidly within the first two months of piling.

1.2.2. Throwing Water on Heated Stones

The air in the sauna room becomes dry when
warmed up. Therefore, it is necessary to throw
water on the heated stones to reach a suitable level
of humidity in the sauna. The effect of heat and
steam on people varies – by experimenting, you
can find the levels of temperature and humidity
that suit you best.
poured on the stones, only part of it will evaporate and
the rest may splash as boiling hot water on the bathers.
Never throw water on the stones when there are
people near the heater, because hot steam may burn
their skin.
The water to be thrown on the heated stones
should meet the requirements of clean household
water (table 1). Only special aromas designed for
sauna water may be used. Follow the instructions
given on the package.
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 that could change the amount or
direction of the air flowing through the heater.
Pay attention especially to the gradual settling
of the stones. Be sure that the heating ele-
