Notes on safety for the first start-up
6.2
Combustion adjustment
In conformity with Efficiency Directive 92/42/EEC, the application
of the burner on the boiler, adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including
verification of the CO and CO2 concentration in the flue gases,
their temperatures and the average temperature of the water in
the boiler.
To suit the required appliance output, choose the proper nozzle
and adjust the pump pressure and the air damper opening in ac-
cordance with the following data.
The values refer to 11.6% of CO
2
at sea level, and with the light
oil and ambient temperature at 10°C.
The values in Tab. D are obtained on a THERMITAL boiler (ac-
cording to EN267). They refer to 12.5 % CO
2
, at sea level and
with an ambient and light oil temperature of 20 °C.

Recommended nozzles
The burner complies with the emission requirements of the EN
267 standard.
In order to guarantee that emissions do not vary, recommended
and/or alternative nozzles specified by manufacturer in the In-
struction and warning booklet should be used.
To set the delivery range within which the nozzle must work, noz-
zle return line fuel pressure must be adjusted.

Pump pressure
14 bar:
The pump is calibrated in the factory as shown in Tab. D.

Start-up, calibration and operation of the burner
WARNING
The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.
WARNING
The combustion air is sucked from outside, there-
fore, there can be sensitive temperature varia-
tions that can influence the percentage value of
the CO
2
. It is advisable to adjust the CO
2
accord-
ing to the diagram.
For example: with an external air temperature of
10°C, adjust the CO
2
to 12.5% (± 0.2%).

WARNING
It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
CAUTION
The use of nozzles other than those specified by
manufacturer and inadequate regular mainte-
nance may result into emission limits non-con-
forming to the values set forth by the regulations
in force, and in extremely serious cases, into po-
tential hazards to people and objects.
The manufacturing company shall not be liable for
any such damage arising from non-observance of
the requirements contained in this manual.
