Sauna Heater Stones - Helo ROCHER DET Product Manual

Installation and User Manual ROCHER DET

2.5. 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 100–150 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.
- 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 9. 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.
