Caution
This water heater is not intended for use by persons with reduced physical,
sensory or mental capacities, or who lack the necessary experience or
knowledge, unless the person responsible for their safety is supervising them or
has explained to them how the water heater should be used.
Caution
This water heater is not intended to be used by children. Always supervise
children, and ensure that they do not play with the water heater.
1.5 Maintenance 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.
