Preparing the heater for use Read the instructions carefully before the first use!

Therefore we recommend the first heating up to be done outdoors or in a well-ventilated sauna room.

Heating up Wood is the only material that should be burned in the heater. Never use materials with high heat capacity, such as particle board, plastic, charcoal or briquettes. Air is circulated by opening the ash drawer. Excess draught will cause the heater to glow, which will significantly shorten its service life. Air circulation should, however, be kept at a reasonable level in order to heat up the sauna rocks to an adequate temperature.

Troubleshooting 1.
