Figure. 6 Rekommended sauna room ventilation
1. Sauna room 3. Electric sauna heater
2. Washroom 4. Exhaust valve
7. A ventilation valve can be installed here to be kept closed while the sauna is heated and during bathing.
Inlet vent can be positioned in the A zone. Make sure the incoming fresh air will not interfere with (i.e. cool down) the
sauna heater's thermostat near the ceiling.
The B zone serves as the incoming air zone, if the sauna room isn't fitted with forced ventilation. In this case, the exhaust
valve is installed min 1m higher than the inlet valve.
DO NOT ISTALL INLET VALVE WITHIN ZONE C, IF THE SAUNA HEATER'S CONTROL SENSOR IS LOCATED IN THE
SAME ZONE.

2.12 Sauna heater stones

Quality stones meet the following requirements:
- Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the
stones.
- Stones should be rinsed before use in order to avoid odour and dust.
- Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
- Sauna stones should be large enough, measuring about 80–120 mm to allow good ventilation between the stones.
This extends the useful life of the heating elements.
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating
elements together or against the frame.
- Rearrange the stones regularly (at least once a year) and replace small and
broken stones with new, larger stones.
- Empty the stone compartment regularly, at least once a year in private use,
remove small and broken stones and replace them with new ones.
- In commercial use this operation must be performed at least every second
month.
- Stones are piled so that they cover the heating elements. Do not, however,
pile a large heap of stones on the heating elements. For a sufficient amount
of stones refer to Table 1 on page 5. Any small stones in the package of stones
must not be piled on the sauna heater.
- The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
- Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered by the
warranty.
- Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
- Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
- DO NOT USE THE HEATER WITHOUT STONES.
