i
Due to the modulating operation of the boiler and the
need to check the gas inlet pressure and measure
the gas rate at maximum rate, it will be necessary to
force it to maximum.
• Activatethetestmode"P.03"andsetthevalueto100in
ordertoforcetheburneratP.max.Seechapter"Specic
