See previous page.
BE AWARE : This function is standard turned off. We offer this programmable function to the installer to use as a
reminder. Because it concerns a free programmable function the use of it cannot be used as an argument in war-
ranty cases. Our units must be maintained every twelve months whatever the settings/working of this function.
It is and remains the responsibly of the end user to have the unit maintained every twelve months.
For more information about this maintenance mode see § 10.14. ‘Setting the maintenance specifications’, page

Service intervals
The normal service frequency for the boiler is once a year. Every year the boiler should be cleaned and checked,
according to the maintenance procedures. If there is doubt whether the boiler is operating with the correct water
and/or combustion air quality, it is advised that a first check is already executed after six months. This check
serves to determine the frequency of the future services. The maximum interval between two services is a year.
INSPECTION AND MAINTENANCE MUST BE EXECUTED FOR A SAFE AND EFFICIENT OPERA-
TION OF THE BOILER.
