Important Information for Sauna Heater Stones
This document serves as an addendum to your Harvia sauna heater user manual. It provides updated guidelines for selecting and arranging sauna stones to ensure the safety and longevity of your heater. Always refer to your primary user manual for specific stone size and quantity requirements for your heater model.
Suitable Stone Materials
For safe and efficient operation, use only the following recommended stone materials:
- Peridotite
- Olivine diabase
- Olivine
- Vulcanite
Use only stones with a cleavage surface and/or rounded stones.
Placement Guidelines
Proper stone placement is critical for safety and air circulation:
- Air Circulation: Stones must be placed loosely to ensure sufficient air circulation through the stone space.
- Electric Heaters: If heating elements are in contact with stones, rounded stones should only be used in the outer layers of the stone space to prevent direct contact with the elements.
- Wood-Burning Stoves: Ensure stones do not come into contact with the hot inner frame of the stove.
Decorative and Ceramic Stones
Special care must be taken with decorative or ceramic stones:
- Only use decorative or ceramic stones if they have been explicitly approved by the manufacturer.
- Decorative stones are suitable only for the top layer of the stone space.
- Ensure decorative stones do not touch heating elements (in electric heaters) or the inner frame (in wood-burning stoves).
Warranty and Maintenance
The user is responsible for the proper maintenance of the stone space. The warranty does not cover defects caused by the use of decorative stones or sauna stones that are not recommended by the manufacturer.
