Introduction	gis

Furthermore, the installation must comply with the manufacturer's instructions.

Note

Later amendments and/or additions to all regulations, requirements and guidelines published on or prior to the moment of installing, will apply to the installation.

The three target groups for this manual are:

•(end) users;

•installation engineers;

•service and maintenance engineers.

Symbols on each page indicate the target groups for whom the information is intended. See the table.

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

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.

The following notation is used in this manual:
