Dimensioning the inlet and outlet ducts
In the list that follows, you will the characteristic losses of load of the original fume venting accessories,
expressed as equivalence in meters (m).
Se fossero previsti accessori di fumisteria originali aggiuntivi rispetto a quelli raffigurati, nel cal-
colo della lunghezza totale devono essere considerate le relative perdite di carico equivalenti,
espresse come equivalenza in metri (m) nell’elenco seguente.
In the case where pipes are installed with non-original accessories (this is allowed by the boiler’s C6
type-approval), but, in any case, absolutely certified for condensation, the installer must consider the
losses of load specified by the manufacturer of these accessories, dimensioning the suction and dis-
charge system so that the total loss of load (expressed in Pa) is between the head loss values of the
boiler fan specified in the paragraph "Technical data" on page 45.
