Start-up, calibration and operation of the burner
8.3
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.
8.4
Pump pressure
8.5
Combustion head setting
This is done when fitting the nozzle, with the blast tube removed.
It depends on the output of the burner and is carried out by rotat-
ing the regulating rod, till the terminal plane of the blast tube is
level with the set-point, as indicated in Tab. H, on page 22.
In Fig. 19, the combustion head is set for an output of 1.50 GPH
at 12 bar, while the shutter is level with set-point 3, as required by
Tab. H, on page 22.
Combustion head settings indicated in Tab. H, on page 22 are
valid for most cases.
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.
Monarch type R
Delavan type B - W
Steinen type Q
Danfoss type B - S
Danfoss tipo ES (only for kerosene)
WARNING
For 2.00 - 3.00 GPH nozzles it is advisable to use,
if possible, full cones.
WARNING
For light oil increase pressure.
8 bar:
the pump leaves the factory set at this value, which is
suitable only for kerosene.
10 bar:
maximum pressure for kerosene.
12 bar:
pressure suitable for gas oil in most cases.
14 bar:
improves flame retention; it is therefore suitable for ig-
nitions at low temperatures.
