Operation Manual

39
- the earth connection is in good working or-
der.
If the socket is not easily accessible, the in-
stallation engineer must provide a switch with
a contact breaking gap of 3 mm or more.
If the appliance power lead is not fitted with
a plug, use an approved standard type, re-
membering that:
- the green-yellow wire must be used for the
earth connection;
- the blue wire is the neutral;
- the brown wire is live;
- the lead must never touch hot surfaces over
about 75 degrees C;
- replacement leads must be of type H05RR-
F or H05V2V2-F of suitable size (see dia-
grams in fig. 2).
- if the appliance is supplied without lead,
using type H05RR-F or H05V2V2-F cable
of suitable size (see diagrams in fig. 2).
IMPORTANT: the manufacturer declines all
liability for damage due to failure to comply
with the regulations and standards in force.
Check that the appliance is correctly con-
nected to the earth (see diagrams in fig. 2 at
the back of the manual).
FOR COOKERS WITH ELECTRIC IGNI-
TION
The correct gaps between the electrode and
the burner are shown in figures 4, 5 and 6.
If no spark is generated, do not keep on try-
ing as this might damage the generator.
Possible causes of malfunctions:
- spark plug damp, dirty or broken;
- electrode-burner gap not correct;
- spark plug wire broken or without sheathing;
- spark discharging to earth (to other parts
of the cooker);
- generator or microswitch damaged;
- air has built up in the pipes (particularly if
the cooker has been out of use for a long
time);
- air-gas mixture incorrect (poor fuel setting).
THE SAFETY DEVICE
The correct gap between the end of the ther-
mocouple sensor and the burner is shown in
figures 4, 5 and 6.
To check that the valve is working properly,
proceed as follows:
- ignite the burner and leave it to work for
about 3 minutes;
- turn off the burner by returning the knob to
off position ( );
- after 90 seconds for hob burners, 60 sec-
onds for oven and grill burners, turn the
knob pointer to the "on" position;
- release the knob in this position and move
a burning match towards the burner; IT
MUST NOT IGNITE.
Time needed to excite the magnet during
ignition: 10 seconds approx.
Automatic tripping time, after flame has been
turned off: not more than 90 seconds for hob
burners; not more than 60 seconds for oven
and grill burners.
IMPORTANT
- Before doing any work inside the cooker,
disconnect the mains plug and shut the gas
tap.
- Never use matches to check the gas cir-
cuit for leaks. If a specific control device is
not available, foam or very soapy water can
be used.
- When re-closing the hob, check that the
electrical wires of the spark plugs (if
present) are not close to the injectors, so
that they cannot run across them.
