1.5 Maintenance
1.6 Notation
A service should be carried out at least once a year, both on the water side and on the gas
side. Among other things, the service interval depends on the water quality, the average
burning time per day and the set water temperature.
Note
To determine the correct service interval, it is recommended to arrange for the service and
maintenance engineer to check the water heater on both the water and gas side within three
months following installation. Based on this check, the best service interval can be
determined.
Note
Regular maintenance extends the service life of the water heater. 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 water heater is not regularly serviced, the warranty will become void.
