WORKING

4.1 COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC the applica-
tion of the burner on the boiler, adjustment and testing must be
carried out observing the instruction manual of the boiler,
including verification of the CO and CO
flue gases, their temperatures and the average temperature of
the water in the boiler.
To suit the required appliance output, choose the proper set-
ting of the combustion head, and the air damper opening.

4.2 COMBUSTION HEAD SETTING

Loose the screw (A), move the elbow (B) so that the rear
plate of the coupling (C) coincides with the set point.
Tighten the screw (A).
Example:
The burner is installed on a 81 kW
boiler with an efficiency of 90%, the
burner input is about 90 kW using the
diagram, the combustion set point is 3.
The diagram is to be used only for initial
settings, to improve air pressure switch
operation or improve combustion, it
may be necessary to reduce this setting
(set point toward position 0).
