To simplify calibration of the gas valve, the “calibration function” can be set directly on the boiler
control panel by proceeding as follows:
1) Press the keys (2-3) together until the display shows the pointer “ ” alongside the symbol
(about 6 seconds).
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.

IMPORTANT:
in the case of conversion from natural gas to propane (LPG), the following operations
must be performed before calibrating the gas valve as illustrated above:
• Turn adjuster screw (V) on the gas valve through the number of complete revolutions specified in
table 3 or 3.1;
• On the control panel display set ignition power parameters H608 and H611. The values to be input
are given in table 3 or 3.1. The programming methods are described in chapter 17;
