Maintenance of MN-120 Ukrinterm

The frequency of maintenance depends on the module's operating time and the quality of the water in the heating system. Pump operation should be checked periodically, air should be bled from the water pipes, the gas filter in the gas block should be cleaned, and the heat exchangers should be flushed if necessary. Gas lines should be inspected twice a month. If necessary, the gap between the ignition electrodes should be adjusted.
