WARNING!!
THE AUTOMATIC CALIBRATION MUST BE DONE IN
CASE OF:
- REPLACEMENT OF: FAN, GAS VALVE, AIR/GAS
MIXER, BURNER, ELECTRODE.
- REPLACEMENT OF P.C.B.
- GAS CHANGEOVER
- ANY MODIFICATION TO THE FOLLOWING
PARAMETERS
220 - SOFT IGNITION
231 - MAX CH ADJUSTABLE
232 - MAX DHW PERCENTAGE
233 - MIN PERCENTAGE
234 - MAX CH PERCENTAGE
4. Preparing the measuring equipment
Connect the calibrated measuring device to the left-hand
combustion outlet by unscrewing the screw and removing the
blanking cover.
ATTENTION!!
THE BOILER CAN NOT BE ACTIVATED IF THE
PRESSURE IS NOT CORRESPONDING TO THE
TABLE SUMMARISING CHANGES
5. Supply dinamic pressure check
Loosen the screw 1 and insert the pressure
gauge connection pipe into the pipe tap.
Switch the boiler on at D.H.W. maximum
power, enabling the “Chimney function”
(press the RESET button for 10 seconds
and press th button > to select D.H.W.
maximum power).
