TECHNICAL FEATURES
(1) Flow calculated with a fixed temperature on the D.H.W. potentiometer of 60 °C for a maximum period of 10 minutes
(2) The gas consumptions refers to the calorific value at standard conditions at 15°C - 1013 mbar
(3) Differential measure between the pressure upstream of the gas valve and the depression in the sealed room
