1.2 Preliminary checks
a
WARNING
– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on
protective gloves.
Commissioning of the GO BF 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).

hot water) turn the multifunctional heating dial t to halfway
through the setting range. The display will show the central
heating water temperature detected at that time. In this case
it is necessary to set the room thermostat(s) to the required
temperature or, if the system has a programmable thermostat,
