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 pro-
tective gloves.
Commissioning of the Brava One 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 techni-
cian: 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).

– on the display, check that the operating mode on the display
is "SUMMER"

and if necessary select it by pressing and
holding the button
s
for at least 1 second. the value of the
delivery sensor detected at that moment will appear on the
display
– open one or more than one hot water tap. The boiler will work
at maximum power until the taps are closed.
Once the boiler has been commissioned in "SUMMER mode"
"WINTER mode"
n
can be selected by pressing and holding the
button
s
for at least 1 second. the value of the heating water
temperature detected at that moment will appear on the dis-
play. In this case it is necessary to adjust the air thermostat/s to
the required temperature or if the system has a chrono-thermo-
stat, check that this is "active" and adjusted.

Adjusting the delivery temperature
If the boiler delivery temperature is to be increased or de-
creased it is possible to act on the
rather than having to modify the specific parameters. The tem-
perature can be set to between 20 and 80°C.
1.5
Adjusting the domestic hot water temper-
ature
If the domestic hot water temperature is to be increased or de-
creased, act on the
r
knob on the control panel. The tempera-
ture can be set to between 10 and 60°C.
