5. Turn off the ON/OFF switch on the
control unit.
Operation with the lower rated heat-
ing output is terminated.
Maintain limits to EN 297 (CO content
< 1000 ppm).
Note
To prevent operating faults and damage,
operate the boiler with uncontaminated
combustion air.
If the actual value falls outside the per-
missible range, check the following:
■ Static and supply pressure (see
page 20)
■ Nozzle pressure (see page 22)
Checking the flue gas monitoring device
1. Pull the flue pipe from the draught
