Sizing the pipework
When calculating the size of the pipework, an appliance pressure
drop of 0.1 MPa is recommended.

15.6 Fault conditions

MPa 0.04 - 0.08
MPa 0.03 - 0.05
In the event of a fault, loads up to a maximum of 95 °C at a pres-
MPa 0.03 - 0.15
sure of 1.2 MPa can occur temporarily in the installation.
