against fault currents to the ground, must be connected
according to the standards in force (maximum allowable leakage
current: 1 mA/kW).
2.8 Grounding and bonding of the equipment (for ranges with
electric ignition of burners)
Ground the equipment through the terminal marked with
on the terminal board where the line arrives. Moreover, connect
the metallic structure of any electric device to the terminal
marked with (bonding).
3 - ADAPTING THE RANGE 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 of the cook top (Fig.4 )
- Remove knobs and control board.
a)Unscrew the union R and replace the nozzle UP with that
indicated in the table T1.
b)Screw down the union R again.
3.2 Replacing nozzles and air registers of the burners of the cook
top (Fig.5)
- Remove knobs and control board.
- Unscrew the nozzle U and replace it with that indicated in the
table T1.
- Unscrew the screw V and set the air adjusting bush at the
distance "A" indicated in the table T1.
- Screw down the screw V tightly and seal it with red paint.
3.3 Replacing the minimum nozzle of the cook top (Fig.1)
- Remove knobs and control board.
- Unscrew the minimum adjusting screw VM from the gas cock
and replace with that indicated in the table T1.
3.4 Replacing the pilot burner nozzles of the gas oven (Fig. 4)
- Remove the lower horizontal panel.
- Unscrew the union R and replace the nozzle UP with that
indicated in the table T1.
- Screw down the union R again.
3.5 Replacing nozzles and air registers of the burners of the gas
oven (Fig.5A)
- Remove the lower horizontal panel and the oven bottom.
- Unscrew the nozzle U and replace with that indicated in the
table T1.
- Unloose the screws V and set the air register at the distance
"A" indicated in the table T1.
- Screw down the screws V tightly and seal with red paint.
3.6 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 tables T5, T5A, T6
and T6A.
- 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 table T1.
- 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.
- Remove the knobs and the control board of the cook top.
- Remove the tight screw of the pipe tap P (see fig. 1) 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 T3; 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
- Insufficient gas feeding pressure.
- Nozzle or pipe clogged.
- The gas cock or the gas valve of the oven are faulty.
- The piezoelectric lighter or the pilot burner cable of the oven
are broken.
5.1a The pilot burner shows a difficult ignition or it fails to ignite
(for ranges with electric ignition)
- The ignition plug is faulty, dirty, or wrongly installed.
- The ignition pushbutton is faulty.
- The ignition transformer is faulty.
- Defect in the electric wiring.
- There is no power supply.
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 or to the gas valve of the
oven.
- Gas feeding pressure drop.
- The gas cock is faulty.
- The gas valve of the oven is faulty.
5.3 The main burners show a difficult ignition or they fail to ignite
- Insufficient gas feeding pressure.
- Nozzles clogged.
- The gas cock is faulty.
- The gas valve is faulty.
