The values given in the tables for nozzle
pressure apply to the following ambient
conditions:
■ Air pressure: 1013 mbar (101.3 kPa)
■ Temperature: 15 °C
Wobbe index see page 20.
Setting the maximum heating output
The maximum heating output for heat-
ing operation can be limited. The limit is
set via the modulation range.
01. Turn off the ON/OFF switch on the
control unit (the boiler shuts down).
