When it may not be suitable

This stove may not be suitable for very large saunas that exceed its heating capacity range, as it is engineered specifically for small and medium spaces. Additionally, it is not ideal for installations where an external firebox tunnel cannot be accommodated through the wall to an adjacent room or outdoor area.

Key specifications

• Heating capacity: 16.5 kW
• Fuel type: Wood
• Design feature: External firebox
• Application: Small to medium-sized saunas

How to use

To use the stove, load dry firewood into the external firebox located in the adjacent room or outside space and ignite it safely. Regulate the draft and airflow using the stove controls to maintain the desired burning rate and temperature. Once the fire is established, the stove will efficiently heat the sauna stones and circulate warm air throughout the steam room. Always ensure proper ventilation in the sauna room and allow the stove to cool down completely before performing routine cleaning or maintenance.

What to consider before purchase

• Ensure the wall structure allows for the installation of the external firebox tunnel between the sauna and the adjacent room
• Verify that the 16.5 kW heating capacity matches the volume of your sauna room
• Check local building and fire safety regulations regarding wood-burning stove installations and chimney requirements

Make sure to use properly seasoned dry firewood and maintain adequate ventilation in the sauna room for safe and efficient operation of your wood-burning stove.
