19. Adjustment tables
The values specified in the tables are only reference inputs for commissioning. The system set-
tings required in each case must be redefined if values such as boiler output, calorific value and
altitude deviate.
A correction is required in any case.
The maximal burner output can only be achieved in mixing head position 17 mm. Due to the variable mixing
head position, the operating behaviour of the burner can be optimised for different heat generators.
