The maximum absorbed current consumption of the external circulation pump may be
230 W (1 Amp). The extra external pump must be selected according to the installation
resistance and the required flow.
As standard the boiler is provided with a water filter in the return pipe of the boiler. With
this, possible contamination of the central heating water is prevented from ending up in
the boiler. The boiler is also provided with an internal safety valve set at 3 bar. This is
connected to the waste discharge together with the condensation discharge.

When the water hardness of the filling water exceeds > 200ppm and the
volume of the installation > 20L/kW the water has to be treated until below
the maximum value of 200ppm.
