3 - ADAPTING THE COOKER TO OTHER TYPES OF GAS
If the feeding gas is not of the group for which the apparatus is
prearranged, transform the equipment through the following
operations.
Nozzles and rating plates are packed in a proper bag supplied
with the equipment.
3.1 Replacing the pilot burner nozzles (Fig.4 )
- Open the doors of the compartment under the cooking basin.
- Unscrew the union R.
- Extract and replace the nozzle UP with that indicated in the
table T2.
- Screw down the union R tightly and seal it with red paint.
3.2 Replacing nozzles and air register of the main burner (Fig.5)
- Open the doors of the compartment under the cooking basin.
- Unscrew the nozzles U and replace them with those indicated
in the tables T2.
- Unloose the screw V and set the air adjusting bush at the
distance "A" indicated in the table T2.
- Screw down the screw V tightly and seal it with red paint.
3.3 Replacing the minimum nozzle (Fig.1)
- Remove knobs and control board.
- Remove the minimum adjusting screw VM from the gas cock
and replace with that indicated in the table T2.
3.4 Replacing the rating plate of gas
- Apply the rating plate indicating the new type of gas onto the
equipment thus transformed.
4 - STARTING
4.1 Checking the operation
Start the equipment according to the instructions of use, and
check:
- the correct operation of pilot and main burners;
- that there are no leaks;
- the correct operation of room ventilation systems;
- the efficiency of the exhaust gas system; if necessary, refer to
the paragraph 5 "Check of some malfunctions";
- whether the data of the rating plate of the equipment
correspond to those of the mains or of the gas pipe network.
Warning: during the operation, take extreme care in
handling the hot areas of the outer surface.
4.2 Checking the thermal power
After installing the equipment and adapting it to another gas
group or in any maintenance operation, check the thermal power.
- The thermal power rating is indicated in the table T1.
- The equipment operates at the power rating when its nozzles
actually correspond to the type of gas supplied and to the
operating pressure indicated in the tables T1, T3 and T4.
- As regards the control of feeding pressure, refer to the
paragraph 4.3 "Checking the gas feeding pressure".
4.3 Checking the gas feeding pressure
- Necessary measuring instrument: pressure gage with minimum
accuracy rating of 0.2 mBar.
- Open the door of the compartment under the cooking basin.
- Remove the tight screw of the pipe tap P (see fig. 1A) and
connect the pipe of the pressure gage to this tap.
- Carry out the measurement while the equipment is operating.
- The measured value must be included within the limits
indicated in the table T4; otherwise, stop the test and call the
gas service company.
- Disconnect the pipe of the pressure gage and screw down the
screw of the pipe tap tightly.
5 - CHECK OF SOME MALFUNCTIONS
5.1 The pilot burner shows a difficult ignition or it fails to ignite
- The piezoelectric lighter, the ignition plug or the pilot burner
cable are faulty.
- Insufficient gas feeding pressure.
- Nozzle or pipe clogged.
- The gas cock is faulty.
5.2 Extinction of pilot burner during the operation
- The thermocouple is faulty, or it is not properly heated, or not
correctly connected to the gas cock.
- Gas feeding pressure drop.
- The gas cock is faulty.
5.3 The main burner shows a difficult ignition or it fails to ignite
- Insufficient gas feeding pressure.
- Nozzles clogged.
- The gas cock is faulty.
6 - REPLACING SOME COMPONENTS
N.B.: The sealed components must not be tampered with.
After any operation, check that there are no leaks, if
necessary.
6.1 Main or pilot burners
- Open the doors of the compartment under the cooking basin.
- Replace the component.
6.2 Thermocouple
- Remove the knobs and the control board.
- Open the doors of the compartment under the cooking basin.
- Disconnect this component from the gas cock.
- Remove the component from the support of the pilot burner
and replace it (fig. 4).
6.3 Gas cock
- Remove knobs and control board.
- Disconnect the pipes and the thermocouple and replace the
gas cock.
6.4 Ignition plug
- Open the door of the compartment under the cooking basin.
- Remove the component from the support of the pilot burner
(fig. 4) and replace it.
6.5 Piezoelectric lighter and pilot burner cable
- Open the door of the compartment under the cooking basin.
- If necessary, remove the piezoelectric lighter from the support.
- To replace the high-voltage cable, disconnect either from the
piezoelectric lighter and from the ignition plug.
- Remove the fastening elements of the cable and replace it.
6.6 Water inlet cock
- Remove knobs and control board.
- Disconnect the pipes and replace the component.
