GB Installation
- press gently on the upper side of the glass so that the three
pins, with silicone on the inside, fi t into their holes.
- make sure that the door closes completely.
ADAPTING TO DIFFERENT TYPES OF GAS
If the cooker is not already preset to operate with the type of gas
available, it must be converted. Proceed as follows:
- Replace the injectors (see table on page 19);
- regulate the primary air fl ow;
- regulate the minimum settings.
N.B.: every time you change the type of gas, indicate the new
type of gas on the operating data plate.
REPLACING THE HOB BURNER INJECTORS (Fig.5)
- Remove the grid, the burner caps (A), and the burners (B);
- Unscrew and remove the injector in the bottom of each injector
holder (C);
- replace the injector,using a 7mm socket, in accordance with the
table in page 19, tighten and screw right down;
- check that the system is gas-tight;
- replace the burners, the burner caps and the grid.
IMPORTANT:
- Never over-tighten the injectors;
- after replacing, check that all the injectors are airtight.
SETTING HOB BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/propane), 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 (accessed
directly). See fi g. 6
If the cooker is to work on natural gas, proceed as follows for
both types of tap:
- Ignite the burner at maximum fl ame;
- 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 fl ame;
- screw the by-pass slowly back in, without pushing the screw-
driver, until the fl ame has apparently shrunk to 1/4 of the ma-
ximum size, checking that it is suffi ciently stable even in quite
strong draughts.
CONNECTING TO THE ELECTRICAL MAINS
Before making the connection, check that:
- the mains voltage is as indicated on the operating data plate;
- 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 fi tted with a plug, use an ap-
proved 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 of suitable size
(see diagrams in fi g. 2).
- if the appliance is supplied without lead, using type H05RR-F
cable of suitable size (see diagrams in fi g. 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 fi g. 2 at the back of the manual).
FOR COOKERS WITH ELECTRIC IGNITION
The correct gaps between the electrode and the burner are shown
in fi gures 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 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 fi gures 7a,7b
To check that the valve is working properly, proceed as fol-
lows:
- 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 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 fl ame has been turned off:
not more than 90.
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 specifi c
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.
