Data Emissione 09/09/2003
3.2 Replacing nozzles and air register of the main burners (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 and T2A.
- Unloose the screw V in each burner and set the air adjusting bush
at the distance "A" indicated in the tables T2 and T2A.
- Screw down the screw V tightly again and seal it with red paint.
3.3 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 T1 - T1A.
- 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 T2, T2a, T3 and T4.
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. 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 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 valve 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 valve.
- Gas feeding pressure drop.
- Intervention of the safety thermostat of manual reset (refer to the
point 6.4)
- The gas valve is faulty.
5.3 The main burners show a difficult ignition or they fail to ignite
- Insufficient gas feeding pressure.
- Nozzles clogged.
- The gas valve is faulty.
- Intervention of the safety thermostat of manual reset (refer to the
point 6.4).
5.4 Difficult control of temperature
- The gas valve 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, high-voltage ignition cable
- Open the doors of the compartment under the cooking basin.
- Remove the control board.
- Disconnect this component from the gas valve
- Remove and replace the component.
6.3 Gas valve
- Open the doors of the equipment, drain all the oil from the
concerned basin (refer to the paragraph 7.6 - Draining the oil).
- Unscrew the stuffing box from the frontal panel of the basin, to
extract the bulb of the valve having to be replaced.
- Remove the control board.
- Disconnect the pipes and the thermocouple of the valve and
replace the valve.
6.4 Safety thermostat
Before enabling the safety thermostat TS (fig. 1) again, eliminate the
reasons provoking the overheating: examine the functioning of the
operating thermostat, the oil level, etc... Then carry out the following
operations:
- Remove the control board.
- Press the red pushbutton of the thermostat.
- Check whether the electric circuit is closed.
Replace the safety thermostat through the following operations:
- Open the doors of the equipment, drain all the oil from the
concerned basin (refer to the paragraph 7.6 - Draining the oil).
- Unscrew the stuffing box from the frontal panel of the basin, to
extract the bulb of the thermostat having to be replaced.
- Remove the control board.
- Disconnect the electrical connections and replace the thermostat.
