(Sauna stones and chimney components sold separately.)
Install the Hive Flow Mini on a non-combustible base with adequate ventilation. Maintain all clearances specified in HUUM’s manual. Connect to an approved chimney system suitable for wood-burning heaters. Only a qualified professional should perform chimney and flue installations. Use HUUM sauna stones for the most consistent heat retention and authentic steam.
Operate the sauna only as directed in its model-specific manual. Keep combustible items clear of hot surfaces, supervise children, and stop use if the unit is damaged or you feel unwell. Sauna bathing involves heat exposure and dehydration risk; ask a healthcare professional if a condition or medication may affect heat tolerance.
