Checking Gas Pressure and Nominal Heat Input (Fig. 4)
At the first installation, specialized technician must control Gas Fryer nominal heat input,
maintenance, and gas conversion. DO NOT improve Gas Fryer 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 2, ± 5% tolerance is allowed. When you are measuring top deviations,
carefully check the diameters and the quality of installed injectors and gas main pressure. If
you want to measure the main pressure while Gas Fryer 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 “M” 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.
