    (see above). Caution Adherence to the conditions issued by Potterton is vital to safe­ guard the warranty. Note The water hardness of the heating water has to be checked within the scope of the recommended maintenance of the boiler and the corresponding amount of additive has to be added if necessary.

  • Page 25: Diagram Of Water Hardness

    The total water volume in the heating system is calculated using the sys­ tem volume (= fill water volume) plus the top-up water volume. In the Potterton boiler-specific diagrams only the system volume is given to make them easier to read. Over the entire service life of the boiler, a maximum top-up volume of twice the system volume is assumed.
  • Page 26 -15 °C is usually sufficient. The heat transfer medium must be diluted 2:1 with water to set this operating point. This mixing ratio has been tested by Potterton in relation to its practical suitability for use with gas condensing boilers.

  • Page 27: Water Hardness Tips

    5 Before installation Caution Keep the installation room frost-free. If an antifreeze agent is used, pipework, radiators and gas con­ densing boilers are protected against frost damage. For the gas condensing boiler to be ready for operation at any time, suitable measures must also be taken to keep the installation room frost- free.
