Maintenance notes
Performing regular cleaning and maintenance
To ensure satisfactory functionality, cleaning and
maintenance must be performed at regular intervals.
You will receive a timely reminder about this from the
ETAtouch control system.
Cleaning of the boiler must be carried out at least
once a year, or when requested by the control
system. Maintenance is necessary at least every
3 years, or when requested by the control system. We
recommend that you perform maintenance annually.
You can also enter into a service agreement for your
heating system. Find out more from your heating
contractor or customer service.
All tasks where the maintenance table reads
"Customer" or "Customer or expert" in the column
"To be carried out by" can be carried out by any trained
adult. Instruction may be provided by the heating
technician or our customer service.
Steps that are marked with "Expert" only can only be
carried out by the heating technician or our customer
service.
