1. Sauna room

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 THERMOSTAT IS LOCATED AT
THE SAME ZONE.
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. The maximum stone capacity is about 60kg. 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.
