taps, with by-pass on the outside on the right (accessed directly).
See figure 7.
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.
SETTING OVEN BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/propane), the ther-
mostat by-pass must be screwed right down.
If the cooker is to work on natural gas, proceed as follows:
- Remove the oven bottom (loosen the screw to remove the bot-
tom);
- ignite the oven burner, turning the knob pointer to the maximum
setting;
- shut the oven door;
- access the thermostat or tap by-pass (see fig. 8);
- back off the thermostat by-pass by about 3 turns;
- after 5 or 6 minutes, turn the knob pointer to the minimum set-
ting;
- slowly re-tighten the by-pass, watching the flame decrease in size
through the window in the closed oven door until the tongue of the
flame is about 4 mm long. Never keep the flame too low. It must
be stable even when the oven door is opened or closed quickly;
- turn off the burner and replace the oven bottom.
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 order.
For direct connection to a power mains, a device that ensures
disconnection from the mains must be installed, with a opening
distance for the contacts that allows for a complete disconnection
under conditions of category III electrical overload, in conformity
with the installation instructions.
If the appliance power lead is not fitted with a plug, use an approved
standard type, remembering 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 diagrams 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 connected to the earth (see
diagrams in fig. 2 at the back of the manual).
FOR COOKERS WITh ELECTRIC IGNITION
The correct gaps between the electrode and the burner are shown
in figures 5 and 6.
If no spark is generated, do not keep on trying as this might dam-
age 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 thermocouple sensor and
the burner is shown in figures 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 seconds 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 circuit 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.
