Firebox as well as other critical elements of the heater, is made of rolled steel of the required thickness that can withstand any estimated loads. High-alloyed corrosion-resistant steel is used for the above heater elements in Pro models. The effective design for heating up the stones and the steam room is due to numerous bends, heat-conducting structural elements, which increase the heat dissipation area. -

Stone chimney connection The diameter of hole for connection to the chimney stack shall be about 20 mm larger than the diameter of the heating flue outlet pipe, so the optimum clearance around the pipe is about 10 mm. If the designed pipe inlet to the stone chimney is at 90°, it is recommended to make the inner edges of the chimney stack bore round (Figure 5) in order to reduce the resistance for flue gas passage.
