HARVIA M3 Sauna Wood Stove Set with Chimney WHP1500 & Sauna Stones

Recommended Accessories
Important Notes on Installation and Use
The installation of a wood-fired sauna stove such as the HARVIA M3 requires professional planning and execution. According to the manufacturer, installation must be carried out by qualified specialists, as both fire safety regulations and technical connection requirements must be met.
Particularly important are the safety distances from combustible materials and the correct positioning of the stove within the room. Adequate air supply must also be ensured, as wood combustion requires a constant oxygen supply. Without sufficient ventilation, the stove’s efficiency can be significantly reduced.
The stove must only be operated with dry wood. A maximum wood length of 35 cm with a diameter of 8–12 cm is recommended. Moist wood not only reduces heating performance but can also significantly shorten the stove’s lifespan.
Sauna stones also play a central role. Only suitable stones with a size of 10–15 cm should be used. These must be properly arranged to allow air circulation between them. Incorrect placement can negatively affect performance. :contentReference[oaicite:0]{index=0}
Before first use, the stove should be pre-burned outdoors, as production residues may be released. Only after this process is the stove fully ready for operation.
The WHP1500 chimney is specifically designed for the stove and ensures safe exhaust gas discharge. Proper installation is essential for the safety and functionality of the entire system.
