3.13 CO ADJUSTMENT
2
Calibration of minimum CO
Enter the chimney sweep phase without withdrawing domestic hot water and take the selector switches to minimum until "0" is seen on
the display.
To have an exact value of CO
specified in the table, otherwise adjust the screw (Det. 3, Fig. 80) (Offset regulator).
To increase the CO value, turn the adjustment screw (3) in a clockwise direction and vice versa to decrease it.
2
Calibration of maximum CO
On completion of the adjustment of the minimum CO
maximum (increase the value until "99" is seen on the display).
To have an exact value of CO
specified in the table below, otherwise adjust the screw (Det. 12, Fig. 80) (gas flow rate regulator).
To increase the CO value, turn the adjustment screw (12) in a clockwise direction and vice versa to decrease it.
