Nozzles installation
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 the manufacturer in the In-
struction and warning booklet should be used.
It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
WARNING
The use of nozzles other than those specified by
the 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.
CAUTION
The manufacturing company shall not be liable for
any such damage arising from nonobservance of
the requirements contained in this manual.

Pump pressure
The pump leaves the factory set for kerosene working.
10 bar: maximum pressure for kerosene.
For gas oil increase pressure.
12 bar: pressure suitable for gas oil in most cases.
14 bar: improves flame retention; it is therefore suitable for
ignitions at low temperatures.
