- Never over-tighten the injectors;
- after replacing, check that all the injectors are
airtight.
SETTING HOB BURNER MINIMUM LEV-
ELS
If the cooker is to work on bottled gas , the tap
by-pass must be screwed right down.
The cooker may be equipped with type A taps,
with by-pass inside (accessed by inserting a
small screwdriver into the rod) or type B taps,
with by-pass on the outside on the right (ac-
cessed directly). See figure 8.
If the cooker is to work on natural gas, proceed
as follows for both types of tap:
- Ignite the burner at maximum flame;
- pull off the knob, without using a lever against
the control panel, which might be damaged;
- access the by-pass with a small screwdriver
and back off by about 3 turns (turning the
screwdriver anti-clockwise);
- turn the tap rod anti-clockwise again until it
stops: the burner will be at maximum flame;
- screw the by-pass slowly back in, without
pushing the screw-driver, until the flame has
apparently shrunk to 1/4 of the maximum
size, checking that it is sufficiently stable even
in quite strong draughts.
Check that the burner does not go out when Check that the burner does not go out when

CONNECTING TO THE ELECTRICAL
MAINS
Before making the connection, check that:
- the mains voltage is as indicated on the
nameplate;
- the earth connection is in good working or-
der.
If the socket is not easily accessible, the instal-
lation 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, remem-
bering 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 HO5RR-F
or H05V2V2-F .
- if the appliance is supplied without lead, using
type HO5RR-F .
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 connected
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,7a,7b,
If no spark is generated, do not keep on trying
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 sheath-
ing;
- 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 7a,7b.
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 seconds
for oven and grill burners, turn the knob
pointer to the "on" position;
- release the knob in this position and move a
