7.4.12 Burner calibration
Also see the chapter “Preparing for operation”.
The Burner Calibration submenu is used to access the procedure for configuring and calibrating the
burners on the humidifier.
Two types of gas can be selected:
l Natural gas (G20-G25);
l LPG (G30-G31).
Note: on selecting the type of gas, the humidifier automatically sets all the control parameters for
correct operation with that specific family of gas.

Ec28 Burners calibration
Start the procedure to calibrate the burners. Follow the instructions
shown on the display
Guided calibration is a step-by-step procedure that helps the installer correctly set up the burner.
It is divided into three different steps:
1. Calibration at maximum fan speed (maximum output delivered by the humidifier);
2. Calibration at minimum fan speed (minimum output delivered by the humidifier=;
3. Verification of calibration at maximum output.
The first step once the type of gas has been selected; the humidifier will be switched on, if off, and
operated at the maximum output available. The screen will show info on the unit operating status, such as
pre-purge, fan speed and waiting. Wait for the humidifier to reach maximum output, then calibrate the
gas valve (see chap. “Type of calibration”), adjusting it so that the percentage of CO2 measured is within
the allowed range.
Repeat the operations for the other two steps, following the instructions shown on the screen, to
complete the calibration procedure.
Note:
l if an alarm is activated during calibration, the procedure stops and a warning message is shown;
l If during calibration no button is pressed for 5 minutes, the procedure will be interrupted and the
unit will return to normal operation.
