We recommend the use of suitable
commercially available products to clean,
sterilise and maintain the boiler. Products

The effectiveness of the use of chemicals to
combat microorganisms in the appliance can
be increased by heating the water in the boiler
to 70 °C at regular intervals.
• Select “Gas mode”.
• Set the water temperature to 60 °C.
• Switch on the appliance.
Once the water in the boiler has
reached a temperature of 60 °C, the
burner will switch off. The appliance
must stay switched on for at least
30 minutes and no hot water may be
removed. The residual heat in the heat
exchanger will heat the water up to
70 °C.
