Warning: During initial lighting, until the air contained in the gas pipes
is not released, the burner may fail to light immediately and that may
cause a ‘blockage’ of the boiler. In this case we recommend you repeat
the ignition procedure until gas is delivered to the burner, setting selector
(1) to ( ) for at least 1 second (see also figure 4).
Room temperature adjustment
The system must be equipped with a room thermostat (see the relevant
regulations) to control the temperature in the rooms.
In case there is no room thermostat, during initial lighting it will be
possible to control the room temperature by turning control (5).
To increase temperature values turn the control clockwise and
anticlockwise to decrease it. Electronic modulation of the flame will
enable the boiler to reach the set temperature by adapting the gas supply
to the burner to the actual heat exchange demand.
DHW temperature adjustment
The gas valve is provided with an electronic flame-
modulating function, which operates depending on
the DHW temperature adjusting control (6) settings
and on the quantity of water drawn from the taps.
This electronic device allows to keep the water
coming out of the boiler at a constant temperature
also when small quantities of water are drawn.
To ensure energy saving and economical manage-
ment of your boiler, we recommend you place the
switch adjusting the hot water temperature on
“comfort” (see figure 2). In wintertime it will be
necessary to increase the DHW temperature
according to needs.
