A service should be carried out at least once a year, both on the water side and  
on the gas side. Maintenance frequency depends, among other things, on the  
water quality, the average burning time per day and the set water temperature.  
1.5 Maintenance  
Note  
To determine the correct maintenance frequency, it is recommended to  
arrange for the service and maintenance engineer to check the appliance on  
both the water and gas side within three months following installation. Based on  
this check, the best maintenance frequency can be determined.  
Note  
Regular maintenance extends the service life of the appliance.  
Note  
Both the end user and the service and maintenance engineer are  
responsible for regular maintenance. They will need to establish clear  
agreements on this.  
Note  
If the appliance is not regularly maintained, the warranty will become void.
