3.6 Sauna heater stones
We recommend that you use Kota olive dolerite stones.
Natural stones are not suitable to be used as sauna heater
stones 10–15 cm. Before using the stones, they must be
washed to eliminate any impurities.
Bigger stones are
placed in the bottom of the stone compartment and
the rest are piled sparsely so that air can move freely
between the stones. Flat stones shall be stacked in
upright position.
The stones must not block air openings
and stones must not be stacked over the top surface of
the sauna heater.
The recommended quantity of stones
in the sauna heater is shown in clause 1.1. The use of
stones with a regular shape (rectangular, etc.) and light or
ceramic stones is forbidden because of a risk of too tight
stacking.
