4.5 Gas Supply Connection
1. Before installing and connecting Gas Table Low to gas supply, carefully control the fixed part of gas system,
which conformed to National Building Regulation.
2. Verify gas pipes sections to guarantee sufficient supply for all gas heated appliances. Install it in similar
condition to avoid excessive pressure drops.
3. The pipes must be made of steel (with junctions made using white cast iron, or galvanized steel fittings, or
autogenously welded joints) or copper pipes (with mechanical joints and couplings without seals or mastics
or brazed joints).
4. Control the gas bottle (if any) placed correctly and protected in dry area.
5. Check whether the gas pipes can easily inspected. If the pipes installed in floor and wall, make sure that this
work done according to professional standard with reference points that make it possible to find the pipes.
6. Before installing Gas Table Low, make sure that it is set for the gas and pressure (see Technical Data
Plates). Consult the paragraph “Gas Conversion”.
7. Connect Gas Table Low 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 Table Low safely, take a pressure test the whole gas circuit by using leak finder spray or
non-corrosive foams.
11. The Gas Table Low 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 Table Low nominal heat input, maintenance,
and gas conversion. DO NOT improve Gas Table Low 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 Table Low 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.
