TECHNICAL DATA.
4.1 VARIABLE HEAT OUTPUT.
N.B.:
the power data in the table have been obtained with in-
take-exhaust pipe measuring 0.5 m in length. Gas flow rates refer
to net calorific value at a temperature of 15°C and at a pressure
of 1013 mbar. Burner pressure values refer to use of gas at 15°C.
Combustion parameters: measuring conditions of useful efficien-
cy (flow temperature/return temperature= 80 / 60 °C), ambient
temperature reference = 15°C.
