11.The Gas Euro Range is equipped with ISO 7/ 1 screw thread, gas connection of ¾ inches diameter and
suitable adapter for ISO 228/ 1 G screw thread gas connection are provided together with the appliance
according to destined countries.
4.6 Checking Gas Pressure and Nominal Heat Input
At the first installation, specialized technician must control Gas Euro Range nominal heat input, maintenance,
and gas conversion. DO NOT improve Gas Euro Range performance and increase nominal heat affirmed by
the manufacturer. Control heat input by using gas counter and chronometer. Measure the exact amount of gas
flow per unit of time which consumed by the appliance at maximum power. Compare the measurement to the
consumption data on Data Technical Table 1, ± 5% tolerance is allowed. When you are measuring top
deviations, carefully check the diameters and the quality of installed nozzles and gas main pressure. If you
want to measure the main pressure while Gas Euro Range is ON and using a pressure gauge for liquids (for
example U manometer, with minimum resolution 0.1 mbar), please follow direction below:
1.Connect the flexible pipe “E” of the Manometer to the inlet pressure point “C” after unscrewing its cap.
2.Measure the connection pressure: if the reading is not within the values given in the following table, the
appliance cannot work properly. The gas company must be informed to find out the supply pressure problems.
If necessary, install a pressure regulator.
3.Once the connection pressure has been measured, disconnect flexible pipe “E”, retighten the screw cap of the
inlet pressure point “C”. Restore the components inversely.
