Before purchasing and installing the Harvia Legend 240 GreenFlame, the responsible chimney sweep or local authority must always be consulted. The suitability of a wood-burning sauna stove depends not only on the stove itself but also on chimney design, building conditions, ventilation requirements, local regulations and flue gas routing. All specifications issued by local authorities and chimney professionals must be followed without exception.
The stove complies with the European EN 15821-2010 standard for wood-burning sauna stoves and carries the required CE marking. For operation within Germany, additional compliance with BImSchV 2 regulations must be observed. Although the GreenFlame® combustion system was specifically developed to achieve lower emissions, every installation must still be individually assessed according to local regulations and building conditions.
The recommended sauna room volume ranges from 10 to 24 m³. Choosing the correct stove size is essential. If installed in a significantly smaller sauna room, overheating may occur. If used in a larger sauna than recommended, the stove may struggle to reach the desired sauna temperature and steam quality. Glass surfaces, insufficient insulation and special construction features may also affect heating requirements and should be considered during planning.
The maximum stone capacity of 200 kg must not be exceeded. Sauna stones must be suitable for wood-burning sauna stoves and positioned to allow unrestricted air circulation. Overpacking the stone compartment or using damaged stones can impair combustion, reduce efficiency and increase mechanical stress on the stove structure.
Special attention must also be given to safety clearances, floor protection, spark protection and proper chimney connection. Wood-burning sauna stoves should never be installed without professional planning. Adequate fresh air supply is equally important because combustion requires sufficient oxygen. Poor ventilation can negatively affect combustion quality, efficiency and operational safety.
Only dry and suitable firewood should be used. The combustion chamber and ash compartment should be inspected and cleaned regularly. The glass door, chimney connection, stone filling and combustion system should also be checked periodically to ensure safe and reliable long-term operation according to the manufacturer's instructions.
