3) Conclusion of the basic calibrations
- once the CO
2
values at minimum and maximum
output have been checked and any adjustments
have been made (sections 1-2):
- disable the timed “calibration” function by switching
off the
main
switch.
- close the flue gas inspection sample points of the
intake and exhaust terminal
-
check that there are no gas leaks.
For proper operation, the CO
2
values
must be calibrated with particular at-
tention, observing the values indicated
in the table.
1) Maximum output adjustment
- Operate the boiler in “calibration” mode at MAXI-
MUM OUTPUT (see 3.11.1)
- Once the burner is on check
that the CO
2
“MAXIMUM” value corresponds to
that indicated in the table “NOZZLES - PRES
-
SURE”.
- if it does not correspond, correct it by turning the
screw
“S”
CLOCKWISE to decrease it, ANTI-
CLOCKWISE to increase it.
2) Minimum output adjustment
- Operate the boiler in “calibration” mode at MINI-
MUM OUTPUT (see 3.11.1)
- Once the burner is on check that the CO
2
“MINI-
MUM” value corresponds to that indicated in the
table “NOZZLES - PRESSURE”.
- Correct it if needed by turning (with a screwdriver)
the screw
“R”;
CLOCKWISE to increase it, ANTI-
CLOCKWISE to decrease it
