Gas - Meritus GB – Gas Range Series
FRM-PDE-03-04
6. Before installing Gas Range Series, make sure that it is set for the gas and pressure (see
Technical Data Plates). Consult the paragraph “Gas Conversion”.
7. Connect Gas Range Series to gas supply using solid fittings or flexible steel pipes with suitable
sections related to nominal power and length.
8. Check whether the flexible pipes does not pass or near hot surfaces, put under stress and
traction, contact with sharp edges, or other things that could damage the pipe.
9. Install quick ON – OFF valve between the gas mains and each single appliance where easy to
reach.
10. After install Gas Range Series safely, take a pressure test the whole gas circuit by using leak
finder spray or non-corrosive foams.
11. The Gas 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.
Checking Gas Pressure and Nominal Heat Input
At the first installation, specialized technician must control Gas Range Series nominal heat input,
maintenance, and gas conversion. DO NOT improve Gas Range Series 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 injectors and gas main pressure. If you want to measure the main pressure while Gas Range
Series 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.
