- Table 1 indicates both the minimum height of the sauna and the minimum safety
distances for the stove.
- Make sure the fixing plate is screwed to a solid base. Wall panelling is not solid
enough, and needs to be reinforced with either additional studs under the panel or
reinforcing boards fixed to the wall studs on top of the panel.
- The stove can also be installed in a wall recess, cf. Fig. 1.

6. LOADING OF STONES
- When loading the stones, make sure they do not bend the resistors or obstruct
sufficient circulation of air.
- Do not load the stones too tightly. Over-filling of the stone compartment will
cause overheating of the resistors (= shorter service life) and slower heating up
of the sauna.
- Suitable stones for the stove are 4-7 cm in diameter.
- The stones shall cover the heating resistors completely.
AN UNDER-FILLED STONE COMPARTMENT WILL CAUSE A FIRE HAZARD!
ALWAYS CHECK THE SAUNA BEFORE SWITCHING ON THE STOVE.

7. VENTILATION IN THE SAUNA
- The ventilation in the sauna should be as efficient as possible in order to ensure
a sufficient oxygen level and freshness of air. We recommend that the fresh air
intake is located near the stove (but not closer than 50 cm).
- The fresh air intake shall be equipped with an adjustable valve.
- The exhaust valve shall be at least twice the size of the fresh air intake. The exhaust
valve can be installed on the opposite wall, at least 20 cm higher than the fresh
air intake.
8. CONSTRUCTION OF SAUNA
- The sauna shall be well heat insulated, particularly the ceiling, where most of
the steam rises. Due to the high level of humidity, the heat insulation should be
covered with moisture-proof material, such as aluminium paper.
Wood should always be used for cladding.
9. PROTECTIVE RAILING
- If required, a protective railing can be built
round the stove. See Fig. 10.
We recommend a wooden railing.
The indicated safety distances to inflammable
structures must be observed.
Improper installation will cause a fire hazard.
