TROUBLESHOOTING
If the hob does not operate correctly, before calling the After-Sales Service,
refer to the Troubleshooting Guide to determine the problem
1.
The burner fails to ignite, or the ame is not even
Check that:
• the gas or electrical supplies are not shut o and especially that the gas
supply tap is open;
• the gas cylinder (liquid gas) is not empty;
• the burner openings are not clogged;
• the plug end is not dirty;
• all the burner parts have been positioned correctly;
• there are no draughts near the hob.
2.
The burner does not stay lit
Check that:
• when lighting the burner, the knob has been pressed for enough time
to activate the protection device;
• the burner openings are not clogged near the thermocouple;
• the end of the safety device is not dirty;

ADJUSTING MINIMUM GAS SETTING OF TAPS
This operation must be performed by a quali ed technician.
The adjustment must be performed with the tap in a minimum gas setting
position (small ame).
The primary air of the burners does not need to be adjusted.
To ensure that the minimum setting is correctly adjusted, remove the knob (F)
and proceed as follows:
•
tighten the screw to reduce the ame height (−);
•
loosen the screw to increase the ame height (+).
At this stage, light up the burners and turn the knobs from maximum position
to minimum position to check ame stability.

Upon completion of adjustment, reseal using sealing wax or an equivalent
material.
CLEANING THE HOB PARTS
•
Clean glass and enamelled parts only with soft cloth or sponge.
•
Grids, burner caps and burners can be removed to be cleaned.
•
Clean them by hand with warm water and non-abrasive detergent,
removing any food residues and checking that none of the burner
openings is clogged.
•
Rinse and dry.
•
The cast-iron grates may be cleaned in the dishwasher.
Remove any burnt-on food before placing the grates in the lowest
rack in the dishwasher.
•
Re t burners and burner caps correctly in the respective housings.
•
When replacing the grids, make sure that the panstand area is aligned
with the burner.

Models equipped with electrical ignition plugs and safety device
require thorough cleaning of the plug end in order to ensure correct
operation. Check these items frequently, and if necessary, clean them
with a damp cloth. Any baked-on food should be removed with a
toothpick or needle.
NOTE: to avoid damaging the electric ignition device, do not use it when
the burners are not in their housing.
3.
The containers are not stable
Check that:
• the bottom of the container is perfectly at;
• the container is centred on the burner;
• the grids have not been exchanged or positioned incorrectly.
If after the above checks the fault still occurs, get in touch with the nearest After
