In order for the boiler to operate correctly, it is imperative
to respect the draught at the nozzle: 0 at the nozzle.
*Maintenance consumption: total heat emission when the burner is
off as a percentage of the nominal input power when the difference
between the mean boiler temperature and the room temperature is
30 K.
(A)Loss when not operating in accordance with NFD 30002 standard
at % of input power.
(B)Nominal operation (top boiler power).
(C)1 mbar = 10 mmCE = 10 daPa.
(D)Pressure in the furnace for nozzle pressure = 0.
In no event must the draught at the nozzle exceed 0.2 mbar.
