3 - ADAPTING THE SOLID TOP 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 nozzle of the solid plate (fig.4)
Remove knobs and control board from the solid top. Unscrew the
union R and replace the nozzle UP with that indicated in the tables
T1 and T1A. Screw down the union R again.
3.2 Replacing nozzles and air registers of the burners of the solid
top (fig.5)
Remove knobs and control board. Unscrew the nozzle U and
replace it with that indicated in the tables T1-T1A. Unloose the
screw V and set the air adjusting bush at the distance "A" indicated
in the tables T1-T1A. Screw down the screw V tightly and seal it
with red paint.
3.3 Replacing the minimum nozzle of solid top and open burners
(fig.1)
Remove knobs and control board. Remove the minimum adjusting
screw VM from the gas cock and replace with that indicated in the
tables T1 - T1A.
3.4 Replacing the pilot burner nozzles of the cook top - open
burners (fig.4 )
Remove knobs and control board. Unscrew the union R and replace
the nozzle UP with that indicated in the tables T1 or T1A. Screw
down the union R again.
3.5 Replacing nozzles and air registers of the burners of the cook
top - open burners (fig.5/A)
Remove knobs and control board. Unscrew the nozzle U and
replace it with that indicated in the tables T1 - T1A. Unscrew the
screw V and set the air adjusting bush at the distance "A" indicated
in the tables T1 - T1A. Screw down the screw V tightly and seal it
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 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 and T6. 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 or T1A. 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 knobs and control board of the
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 T2; 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 burners of solid top & open burners show a difficult
ignition or they fail to ignite
Insufficient gas feeding pressure. Nozzle or pipe clogged. The gas
cock is faulty.
Solid top - Piezoelectric lighter or pilot burner cable faulty.
5.2 Extinction of pilot burner during the operation of solid top and
open burners
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 burners of solid top & open burners show a difficult
ignition or they fail to ignite
Insufficient gas feeding pressure. Nozzles clogged. The gas cock is
faulty.
5.4 Oven
5.4.1 The heating of the cooking compartment is not enabled
Possible causes: the oven is not powered. the safety thermostat is
enabled (the green LED is on, the yellow LED is off). The control
thermostat is faulty.
5.4.2 Insufficient heating
Possible causes: one or more resistors are faulty. The switch is
faulty. A phase of the power supply is missing.
5.4.3 Difficult control of temperature
Possible causes: the control thermostat 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 burner of the solid top
Remove the knobs and the control board, then remove the griddle
plate. Unscrew the gas pipe reaching the nozzle support.
Unloose the three screws fixing the main burner to the top, from
above. Extract the burner from the top.
6.2 Thermocouple, pilot burner of the solid top
Remove the knobs and the control board, then remove the griddle
plate. Replace the component.
