## Long description

The Harvia M90 9 kW electric sauna stove in black is designed for traditional Finnish-style steam and dry saunas in home and small commercial settings.

How to use
Install the Harvia M90 9 kW heater according to the manufacturer’s installation instructions and local electrical codes, ensuring correct clearances and secure wall mounting. Fill the stone compartment with sauna stones rated for stove use and position them to allow airflow around each stone. Connect the heater to a suitably rated electrical supply and control system; set the desired temperature and allow the unit to reach operating temperature before beginning a sauna session. For steam generation, ladle water onto the heated stones in measured amounts to achieve the preferred humidity level. Always follow safety guidance in the manual regarding maximum stone and water amounts and avoid direct contact with hot surfaces.
Usage recommendations
Use only stones specified for sauna stoves and replace cracked stones regularly to maintain even heating. Verify that the control unit and wiring are rated for 9 kW operation and arrange periodic visual checks of mounting and stone placement. Keep combustible materials away from the heater and follow ventilation recommendations for safe and comfortable sauna use.
