Harvia Sauna Heater Stones Usage Guidelines

Important Safety Information

The selection and maintenance of sauna heater stones are critical for the safe operation of your sauna unit. Using incorrect stones or improper installation can compromise safety and void your product warranty. Always refer to your specific heater's user manual for the required stone size and quantity.

Suitable Stone Materials

For optimal performance and safety, use only stones specifically intended for sauna heaters. Recommended materials include:

• Peridotite
• Olivine diabase
• Olivine
• Vulcanite

Use only stones with a cleavage surface and/or rounded stones. Ensure that the stones are placed according to the manufacturer's specifications.

Installation Guidelines

Proper stone placement is essential for air circulation and preventing damage to the heater components:

• Electric Heaters: If heating elements are in direct contact with stones, use rounded stones only in the outer layers of the stone space to avoid direct contact with the elements.
• Decorative Stones: These are only suitable for the top layer of the stone space. They must be placed loosely to ensure sufficient air circulation and must not touch heating elements.
• Wood-burning Stoves: Ensure that stones do not come into contact with the stove's hot inner frame.
• Ceramic Stones: Only use ceramic or decorative stones if they have been explicitly approved by the manufacturer and are used in accordance with their specific instructions.

Maintenance and Warranty

The user is responsible for the proper maintenance of the stone space. Regularly check the condition of the stones and rearrange them as necessary to maintain airflow. The warranty does not cover defects caused by the use of decorative stones or sauna stones that are not recommended by the manufacturer. Failure to maintain the stone space according to these instructions may result in the invalidation of the warranty.
