Instructions for Using Your Harvia Sauna Heater
Piling of the Sauna Stones
Properly arranging sauna heater stones is essential for both safety and warranty compliance. Follow these guidelines:
Use suitable sauna stone materials such as peridotite, olivine diabase, olivine, and vulcanite.
Only use cleavage surfaces and/or rounded stones on your sauna heater.
If heating elements come into contact with the stones, use rounded stones only in the outer layers of the stone space.
Decorative stones should be placed loosely to allow air circulation and should not touch heating elements.
Stones should be 5–15 cm in diameter.
Wash off dust from the stones before piling them into the heater.
When placing the stones, don’t drop stones into the heater.
Don’t wedge stones between heating elements.
Space stones to ensure proper air circulation.
Pile stones to support each other rather than placing the weight on heating elements.
Avoid forming a high pile of stones on top of the heater.
Don’t place any objects or devices inside or near the heater that could alter airflow.
Heater Maintenance
Sauna stones can disintegrate due to temperature fluctuations. Rearrange stones at least annually, or more often with frequent sauna use.
Remove any disintegrated stones from the heater’s bottom and replace them with new ones to maintain optimal heating and prevent overheating.
Heating Your Sauna with Harvia Sauna Heater
When using the heater for the first time, both the heater and stones may emit odors. Efficiently ventilate the sauna room to remove these odors. If the heater’s output matches the sauna room’s size, it will take about an hour for a properly insulated sauna to reach the desired bathing temperature. The sauna stones typically reach this temperature simultaneously with the sauna room.
