Carry out the following operations in the given sequence:
1)
Calibration of the max­imum heat output. Check that the CO
2
measured on the flue, with the boiler operating at the
max­imum heat output, is the same as that shown in table 1. Otherwise, turn the regulation screw (V) on the gas valve.
Turn the screw clockwise to reduce the concentration of CO
2
and anticlockwise to increase it.
2) Calibration of reduced heat output. Check that the CO
2
measured on the flue, with the boiler operating at the minimum
heat output, is the same as that shown in table 1. Otherwise, turn the offset regulation screw (K) on the gas valve. Turn
the screw clockwise to increase the concentration of CO
2
and anticlockwise to reduce it.

iMportant: If the appliance is being converted from natural gas to propane (LPG), the following operations must be
performed before calibrating the gas valve as instructed above.
• Turn adjuster screw (V) on the gas valve clockwise through the number of complete revolutions specified in table 3.
To simplify calibration of the gas valve, the “calibration function” can be set directly on the boiler control panel by pro-
ceeding as follows:
1) Press the keys (2-3) together until the display shows the pointer “ ” alongside the symbol (about 6 secon-
ds).
2) Press the keys to set the fan speed at the minimum and max­imum heat output (%PWM);
N.b - to set the
minimum
and
maximum
heat output quickly, press the keys respectively;
3) press either of the two keys to ex­it the function.
