All boilers are factory calibrated and tested. If necessary,
recalibrate the gas valves (MODULE1, MODULE 2, etc.)
2) Adjustment at minimum power
:
- Start the boiler in “calibration” mode at MINIMUM POWER (see
3.12.1)
- Once the burner is on, check that the CO2 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 (refer to the “NOZZLES - PRESSURES” table).
1) Adjustment at maximum power:
- Start the boiler in “calibration” mode at MAXIMUM POWER (see
