Installation, service and operating instruction
16
 Drainage pipe from the safety valve must be taken to floor gully.
 Energy meters must be installed at a prepared location, replacing a gauge block, or following the
instructions of the energy supplier.
 Retighten all connections, including those made at the factory. Tighten with 45 Nm. If connections need
retightening after the installation has been taken into service, the system should be depressurised
before retightening. If the system is not depressurised before retightening, gaskets will be damaged.
 Connect the pipe work to the first fix-jig (option) connection points. Tighten with 45 Nm.
 Bleed the heating system.
Start the heating circulation pump with the highest output setting. Let the heating system heat up and
bleed the system again.
 Set the pump capacity of the heating circulation pump according to the pressure head diagram.
Use the lowest setting that manages the heating demand for best electrical efficiency.
