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
Combustion air is drawn in from outside, meaning
there may be notable changes in temperature,
which can affect the percentage of CO

.
You are advised to adjust CO

in accordance with
the graph featured.
Exemple: outside air temperature 10 °C, adjust
CO
2
to 11.6% (± 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

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
