When piling the sauna stones in the Harvia TRC70E Electric Sauna Heater, it is important to follow these guidelines:
1. Use sauna stones that are 5-10 cm in diameter and are angular split-face sauna stones intended for use in a heater. Suitable stone types include peridotite, olivine-dolerite, and olivine.
2. Do not use light, porous ceramic "stones" or soft soapstones as they do not absorb enough heat and can damage the heating elements.
3. Wash off dust from the stones before piling them into the heater.
4. The aim is to pile a dense layer of stones against the steel grid and pile the rest of the stones loosely. The dense layer prevents direct heat radiation from overheating materials around the heater. Be careful with the corners where the heating elements are near the grid.
5. Do not drop stones into the heater or wedge them between the heating elements.
6. Pile the stones so that they support each other instead of lying their weight on the heating elements. Support the heating elements with stones to keep them vertically straight.
7. Do not form a high pile of stones on top of the heater.
8. Do not place any objects or devices inside the heater stone space or near the heater that could change the amount or direction of the air flowing through the heater.
It is important to properly pile the sauna stones to ensure optimal heating capability and to prevent damage to the heater.
