4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the
application 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
2
concentration in the flue gases, their temper-
atures and the average temperature of the water in
the boiler.
WARNING
Combustion air is drawn in from outside, meaning
there may be notable changes in temperature, which
can affect the percentage of CO
2
. You are advised to
adjust CO
2
in accordance with the graph featured.
Exemple: Outside air temperature 25 °C, adjust CO
2
to 12.25% (± 0.2%).
SETTINGS CARRIED OUT IN THE FACTORY
4.2
NOZZLES RECOMMENDED :
Delavan type W; Steinen type Q; Danfoss type S.
Angle : 60° -
In most cases.
80° -
In case of flame detachment, during ignitions at low
temperatures.
4.3 PUMP PRESSURE
12 bar:
pressure suitable for light oil in most cases.
14 bar:
improves flame retention; it is therefore suitable for ignitions at low temperatures.
4.4 ELECTRODES SETTING
Before removing or assembling the noz-
zle, loosen the screw (
A
, fig. 9) and
move the electrodes ahead.
