Add-on module for Iskander 18M/P2

The additional sauna heater extension module is suitable for Iskander 18 and Iskander 25 stoves and is mounted on the sauna heater module. It adds 55 mm to the depth of the sauna heater, which allows to load more stones. In the “ZK” version the stove initially has 1 module in the set. If a standard height grid is used, a maximum of 2 modules can be installed. In other cases, the number of modules is not limited.
