(otherwise, follow the instructions given in E.6.6 Conver-
sion to another type of gas paragraph of this section).
The supply pressure must be measured while the appli-
ance operates, using a pressure gauge (min. 0.1 mbar).
2. Remove the control panel and retaining screw "N" from
the pressure point (see Valve — Fig. 1);
3. Connect the manometer "O" (see Manometer — Fig. 3);
4. Compare the value read on the manometer with that given
in Table "B" (see Appendix);
If the manometer gives a reading outside the range of
values in Table "B" (see Appendix), do not switch the
appliance on, and consult the gas company.
E.7.2
Primary air checking
The primary air is correctly adjusted when the flame does not
float with the burner cold and there is no flareback with the
burner hot.
1. Undo screw "A" (see Frytop burner — Fig. 2);
2. Position aerator "B" at distance "H" given in Table "B" (see
Appendix);
3. Retighten screw "A" and seal with paint.
E.7.3
Main burner nozzle replacement
1. Unscrew nozzle "C" (see Frytop burner — Fig. 2) and
replace it with one suitable for the type of gas, according
to that given in table "B" (see Appendix);
The nozzle diameter is given in hundredths of mm on the
nozzle body.
2. Fully retighten nozzle "C".
E.7.4
Pilot burner nozzle replacement
1. Undo screw coupling "H" (see Frytop pilot — Fig. 4);
2. Replace nozzle "G" with one suitable for the type of gas
(table "B", Appendix);
The nozzle identification number is indicated on nozzle
body.
3. Retighten screw coupling "H".
E.7.5
Minimum flame screw
1. Unscrew minimum flame screw "M" from the valve (see
Valve — Fig. 1);
2. Replace it with the one suitable for the type of gas;
3. Screw it down fully (see table "B" in the Appendix).
E.8
Before completing the installation
operations
• Use soapy water to check all gas connections for leaks.
• DO NOT use a open flame to check for gas leaks.
• Light all the burners separately and also together, to check
correct operation of the gas valves, rings and lighting.
• For each burner, adjust the flame regulator to the lowest
setting, individually and together.
• After completing the operations, the installer must instruct
the user on the correct method of use.
If the appliance does not work properly after carrying out all the
checks, contact the local Customer Care service centre.
E.9
Replacing the adjustment spring of the
pressure regulator (Only for Australia)
To replace the spring "D" of the pressure regulator with one
suitable for the gas pressure type indicated in table "B" (see
Appendix) proceed as follows:
1. Remove the seal cap "A", the seal cap gasket "B", the
adjusting screw "C" and the spring "D" (see image);
2. Insert the new spring (blue colour = propane gas; silver
colour = natural gas) and replace the adjusting screw;
3. Connect a pressure gauge to the appliance's test point
pressure – (see paragraph E.7.1 Supply pressure check-
ing (all versions));
4. Ignite the appliance's burners so to have the maximum
gas consumption;
18
5. Regulate the adjustment screw until the pressure gauge
shows the working pressure value (see paragraph E.6.5
Gas pressure regulator);
6. Replace the seal cap and gasket and screw tightly closed;
7. Remove the pressure gauge and close the test point
pressure;
8. Prior to operation, test the gas pressure regulator for leaks.
