Service interval
14.1 Introduction
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
Regular maintenance extends the service life of the water heater.
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 three months after installation. Based on this check, the best
service interval can be determined.
14.2 Determining service
interval
The service interval is a feature of the controller to help the service and
maintenance engineer set the maintenance frequency, based on the number of
months that the appliance has been running.
The service interval can be set to: 6, 9 or 12 months. The default setting is 12
months.
Once the set number of months has elapsed, the message
SERVICE REQUIRED
will appear on the display. When this message
appears, the service and maintenance engineer must be contacted.
