15 COMMISSIONING
15.1
Preliminary checks
Commissioning of the Brava One boiler must be carried out by
professionally qualified Personnel after which the boiler can
operate automatically. It may however be necessary for the
User to start the appliance autonomously without involving a
technician: for example, after a holiday . In these cases certain
checks and the following operations must be carried:
– check that the gas isolation and water system valves are
open
– using a pressure gauge (1), check that the heating system
pressure when cold is 1-1.2 bar . If this is not the case, open
the filling valve (2) and restore the heating system pressure
until the pressure gauge (1) shows a reading of 1-1.2 bar
– close the filling valve (2).

Adjusting the delivery temperature
If the boiler delivery temperature is to be increased or decre-
