Maintenance
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.
n
Caution
To determine the correct maintenance frequency, 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 maintenance frequency can be determined.
n
Caution
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.
n
Caution
If the water heater is not regularly maintained, the warranty will become void.
