• After cleaning refit the turbulator, close the cleaning door again and evenly tighten
the screws.

The boiler cleaning must be performed according to existing regulations..
9.6 Spiro-Condens system cleaning
In normal operation the Spiro-Condens system is self-cleaning. For recurring
operation faults and increasing flue gas temperatures, it is probably necessary to clean
the spiral finned tube of the flue gas heat exchanger. The cleaning is performed by rins-
ing or for very severe dirt by removing the spiral finned tube and cleaning.
The boiler must be disconnected from the mains when cleaning it.
Standard cleaning - once a year in connection with maintenance (regular checks, boiler
cleaning, etc.) recommended:
1. Deactivate operating switch.
2. Remove rear cover plate.
