Gas pressure diagrams in appendix
Minimum gas pressure required are
indicated in the diagrams in the appendix.
These values have been determined in
our test labs and are useful for the first
switch-on as final setting must be done
using a combustion analyzer.
How to read and adjust the values:
- determine the output required
- determine the combustion chamber back-
pressure
- read the minimum gas pressure required
in the diagrams in appendix.

Warning: the pre-calibration values have
been determined on EN676 test combu-
stion chambers in ideal conditions, and are
useful for the first switch-on but must be
checked and corrected with calibration for
the individual system.
Example in figure:
Power required by the generator: 380 kW.
Pressure envisaged in combustion cham-
ber: 3.5 mbar. Combustion head chamber:
2.5 (between 2 and 3). Gas pressure in
head: 13 mbar.

Optimising combustion values
The factory setting shall be modified
according to the output requeired.
N.B. observe the minimum required
flue gas temperature specified by
the boiler manufacturer and the
WARNING
requirements demanded of ue gas ducts
for avoiding condensation.
Warning: Recording of initial
commissioning data is recom­
mended.
Regulating the combustion of the one­
stage burner
• position the air valve in the fully open set-
ting (pos. 4).
(for particularly low power only, if the re-
duction of air is not sufficient with the head
in position 1, reduce the opening of the air
valve).
• dose the air by moving the combustion
head (figure) to suit the power required (as
shown in figure).
• dose the gas by regulating the gas ramp
(see figure in the ramp manual).
Firing head setting (1).
To act on the screw in fi gure:
• turn Allen key till you reach the
requested value (index 1-5).
