Replacing the injectors
™ Remove the grids and burner caps from the cooktop
™ Using a socket wrench, replace the injectors "J" (fig. 43) with the suitable ones for the gas
used.
™ Replace the burners.
The burners do non require primary air adjustment.
Adjustment of minimum setting
After replacing the injectors, light the burner and remove the knob. Turn the tap to the minimum
setting and insert a screwdriver in the rod: tighten to reduce the flame, loosen to increase the
flame. (fig. 43)
For gas G30/G31, tighten the adjustment screw fully
The flame must be small, uniform and regular all around the burner crown.
Finally, check that the flame does not go out by rapidly turning the tap from the maximum setting to
the minimum. For burners with a safety device, check that the flame slightly licks the thermocouple.
Make sure that the adjustment is correct by leaving the burner alight for a few minutes. If it goes
out, increase the minimum setting.
CLEANING
To maintain the cooktop in optimum condition, clean it regularly after each use, allowing it to cool
before cleaning.
Never remove the knobs from their seats
Cast Iron Parts
All enamelled parts should be cleaned with a sponge and soapy water or specific detergents.
Never use abrasive cleaning products. Dry thoroughly after cleaning.
Stainless steel top
The stainless steel top should be cleaned with a damp cloth and proprietary detergents
commercially available.
After rinsing, dry preferably with a chamois leather.
Grids
Stainless steel panstand grids may take on a bluish tinge on parts around the burners as a result of
the high temperatures. This effect can be reduced by using commercially available steel wool pads
.
Burners
The burners, comprising two parts, can be removed and cleaned using suitable detergents. After
cleaning, dry the burners thoroughly and reposition them carefully in their seats.
In models with electric ignition, always check that the electrode "E" (fig. 45) is clean.
In models with safety device, clean the probe "T" (fig. 45) in order to allow regular operation of the
safety valve. Both the electrode and probe must be cleaned with care.
Upon completion of cleaning, replace the burners accurately in their seats.
To prevent damaging the electric ignition, avoid using it when the burners are not in place.
Electric hotplates
The electric hotplates should be cleaned when they are only slightly warm.
Clean with a damp cloth, then finish off with a cloth dampened with mineral oil.
