Bentone B40 MF/B45-2 MF
For installers
2.5 Nozzle selection
See under Technical data: Recommended nozzle and Nozzle table.
If, after selecting the nozzle, burner type B45-2 MF has difficulty starting, this
may in some cases be due to the selection of nozzle made for the first stage.
Selecting a nozzle with a smaller effect in the first stage may solve the
problem.
2.6 Setting of brake plate and air flow
Prior to commissioning, the basic settings of the burner can be set in
accordance with the diagram. See under Basic settings. Note that it is simply
a matter of a basic setting that should be adjusted retrospectively once the
burner has started. You should then conduct a flue gas analysis and soot
quantity measurement.
