Inside of oven: 

The oven should 

always be cleaned after use when it 

has cooled down . The cavity should be 

cleaned using a mild detergent solution 

and warm water . Suitable proprietary 

chemical cleaners may be used only 

on  enamel  after  first  consulting  the 

instructions supplied with the oven 

cleaner and testing a small sample 

on the oven cavity . Abrasive cleaning 

agents or scouring pads/cloths should 

not be used on the cavity surface .

 

NOTE: 

The manufacturers of this 

appliance will accept no responsibility 

for damage caused by chemical or 

abrasive cleaning .

 

Let the oven cool down and pay 

special attention not to touch the 

hot heating elements inside the 

oven cavity.

REPLACING THE OVEN LIGHT BULB

Switch the cooker off at the mains.

When the cooker is cool unscrew and 

replace the bulb with another one resistant 

to high temperatures (300°C), voltage 

230V, 50 Hz, type E14 and same power 

(check watt power as stamped in the bulb 

itself) of the replaced bulb .
Note: Oven bulb replacement is not 

covered by your guarantee .

CORRECT REPLACEMENT OF THE 

AUXILIARY, SEMI-RAPID AND RAPID 

BURNERS

It is very important to check that the burner 

flame distributor “

F

” and the cap “

C

” have 

been  correctly  positioned  (see  figs.  8.1, 

8 .2) - failure to do so can cause serious 

problems .

CORRECT REPLACEMENT  OF THE 

TRIPLE RING BURNER

The triple ring burner must be correctly 

positioned  (see  fig.  8.5);  the  burner  rib 

must be enter in their logement as shown 

by the arrow (see fig. 8.3).

Then position the cap “

A

” and the ring “

B

” 

(figs. 8.4, 8.5).

The burner correctly positioned must not 

rotate (fig. 8.4).

BURNERS AND PAN SUPPORTS

These parts can be removed and cleaned 

as indicated previously .

After cleaning, the burners and their flame 

spreaders must be well dried and correctly 

replaced .

It is very important to check that the burner 

flame  spreader  and  the  cap  have  been 

correctly positioned . Failure to do so can 

cause serious problems .

Check that the electrode “

S

”  (figs.  8.1, 

8 .3) next to each burner is always clean to 

ensure trouble-free sparking .

Check that the probe “

T

” (figs. 8.1, 8.3) next 

to each burner is always clean to ensure 

correct operation of the safety valves .

Both the probe and ignition plug must 

be very carefully cleaned.
Note: To avoid damage to the electric 

ignition do not use it when the burners 

are not in place.
