Adjusting the burner
The combustion heating output of the burner must not
exceed the permissible combustion heating output of
the boiler. Adjust the maximum gas or oil throughput of
the burner to the rated boiler heating output.
Use of low-NO
burners

Incorrectly adjusted low-NO
els of vibration and resonance during operation. This
phenomenon can result in damage to the thermal insu-
lation in the area of the boiler door/doors, the cleaning
aperture covers and the flue gas collectors.
