Overpacked sauna rocks
A Sauna rocks should be placed in the heater so that air is free to circulate among them. Overpacking the rocks can cause the unit to overheat, thereby triggering the high-limit temperature device. Before loading the rocks, verify that the heater is securely mounted to the wall or floor, and make sure the heater is off and cool.
5 ENJOY. Now your sauna is primed and ready to go. Simply throw down a towel and relax in the soothing warmth of your sweat bath retreat.
