Maintenance
frequency
14.1 Introduction
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.
Note
Regular maintenance extends the service life of the appliance.
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, three months after installation. Based on this check, the
best maintenance frequency can be determined.
14.2 Determining service
interval
To aid servicing, the electronic controller has a service interval with which the
service and maintenance engineer can determine the frequency of
maintenance, based on the number of burning hours.
The service interval can be set to: 500, 1000 or 1500 burning hours. The
standard setting is 500 burning hours.
Example
In the first three months, the appliance has burnt 300 hours. During
maintenance, it is evident that one service per year will be sufficient. Therefore,
after one year, some 1200 burning hours will have elapsed. The first value below
1200 hours that can be selected is 1000 burning hours.
In this case, the service and maintenance engineer sets the interval to 1000.
In the first three months, the appliance has burned for 300 hours. During
maintenance, it is evident (perhaps due to the water quality) that service will be
required at least once every 6 months.
Therefore, after six months, some 600 burning hours will have elapsed. The first
value below 600 hours that can be selected is 500 burning hours.
In this case, the service and maintenance engineer sets the interval to 500.
Once the set number of burning hours has elapsed, the message
SERVICE REQUIRED
will appear on the display. When this message
appears, the service and maintenance engineer must be contacted.
