Once the required output has been set (maximum heating), indicate
the value on the self-adhesive label supplied. For subsequent con-
trols and adjustments, refer to the set value.
9 The calibration does not entail the ignition of the boiler. By rotat-
ing the heating setpoint selector knob, the value expressed in
hundreds (e.g. 25 = 2500 rpm) is automatically displayed.
The boiler is supplied with the adjustments shown in the table. De-
pending on plant engineering requirements or regional flue gas
emission limits it is, however, possible to modify this value, referring
to the graphs below.
