Wolf CGB-11 Installation Instructions Manual page 15

Heating circuit
We recommend the installation of a maintenance valve into the
central heating flow and return – angled version for installations
below the surface, straight version for surface mounting.
Notes:
Provide a fill and drain valve at the lowest system point.
The heating circuit pump speed can be adjusted and can,
therefore, be matched to various system requirements. Install
an external overflow valve if flow noises still occur.
Heating circuit safety valve
Install a safety valve with marking „H", max. 3 bar.
Cold water and DHW connection
We recommend the installation of a maintenance valve into
the cold water supply. A tested and certified pressure reducer
must be installed, if the cold water supply pressure is above
the maximum operating pressure of 10 bar.
Provide a centralised pressure reducer, if mixer taps are
used.
Observe the regulations of your local water supply company
when connecting cold water and DHW.
Your guarantee rights may be affected if the installation does
not comply with the illustration shown.
