3.2. Place and Safety Distances

The minimum safety distances are described in
figure 4 and 6.
It is absolutely necessary to install the heater
according to these values. Neglecting them
causes a risk of fire. ( 3.7.)
Hot pieces of stone can damage floor coverings
and cause a risk of fire. The floor coverings of
the installation place should be heat-resistant.

3.3. Heater fence

It is necessary for safety and should be constructed
of softwood to match sauna interior. See figures
4 and 6 for clearances from sauna heater. Fence
should be attached to wall and should not be placed
higher than top of heater below rock line.
