Calibration menu MANU
Pressure adjustments must be carried out by a qualified
technician
The following operations must be performed in sequence
Before calibration check the mains pressure.
To calibrate the gas valve (standard procedure MANU: partial ca-
libration +/- 1,5 mbar):
- Place the electric switch of the system to off
- Remove the casing by unscrewing the fastening screws located
at the bottom of the water heater and detached the casing from
the top
- Remove the cover that closes the service inlet (located on the
shelf - fig. 11 pag. 61) and insert through the hole the silicon
