3.9.2 POSITIONING THE PROBES
In order to determine the combustion efficiency, the following meas-
urements must be taken:
- measure the combustion air temperature
- measure the flue gas temperature and content of CO
2
withdrawn from
the hole 2.
Take the specific measurements with the generator at full speed.
3.10 BURNER ADJUSTMENT
All boilers are factory calibrated and tested. If necessary,
recalibrate the gas valves (MODULE1, MODULE 2).
- Remove the cap and insert the CO2 analysis probe into the flue gas
output of the intake/exhaust terminal.
All of the instructions below are provided for the exclu-
sive use of

1) Adjustment at maximum power
- Start the boiler in “calibration” mode at MAXIMUM POWER.
- Once the burner is on, check that the CO
2
value at “MAXIMUM”
power corresponds with what is indicated in the “NOZZLES - PRES-
SURES” table.
- If necessary, correct the value by turning adjusting screw “S” CLOCK-
WISE to decrease it and ANTICLOCKWISE to increase it.
2) Adjustment at minimum power
- Start the boiler in “calibration” mode at MINIMUM POWER.
- Once the burner is on, check that the CO
2
value at “MINIMUM”
power corresponds with what is indicated in the “NOZZLES - PRES-
SURES” table.
- If necessary, correct the value by turning (using a 2.5 mm Allen
key) screw “R”; CLOCKWISE increases it and ANTICLOCKWISE
decreases it.
ATTENTION!
Remove cap 2, insert the CO
2
anal-
ysis probe into the hole.
