CARE AND MAINTENANCE OF THE APPLIANCE
Cleaning
ATTENTION! Before doing any cleaning, make sure that the appliance is disconnected from
the electric mains and that the gas cut off valve is closed. During cleaning operations, avoid
using direct or high pressure sprays of water on the appliance. Cleaning must be done when
the appliance is cold.
Steel parts can be cleaned with warm water and neutral detergent, using a cloth. The detergent
should be suitable for cleaning stainless steel and should not contain abrasive or corrosive
substances. Do not use ordinary steel wool or anything similar, as this can deposit rust-forming iron
particles, and avoid contact of iron objects with the stainless steel. It is also unadvisable to use
sandpaper or emery paper. Pumice powder should only be used for heavily encrusted dirt; however,
a synthetic abrasive sponge or stainless steel wool used in the direction of the glazed finish would
be preferable. After washing, dry the appliance with a soft cloth.
When cleaning, abrasive powders of any type, chlorine-based detergents and bleach should all be
avoided. Also avoid pouring cold liquids on appliances while they are hot, or cracks could form
which could cause the appliance to become deformed or broken.
The stainless steel should not be exposed to prolonged contact with concentrated acidic substances
(vinegar, condiments, spice mixtures, concentrated kitchen salt...) as these can create chemical and
physical conditions that damage the passivation of the steel; it is therefore advisable to remove
these substances using clean water.
When cleaning the cooking plate, it is advisable to remove all burnt food residues with a scraper;
then proceed by using a detergent suitable for cleaning steel and being in contact with food. After
using detergents, the plate should be washed well with clean water. Cleaning operations are easier if
they are carried our when the cooking plate is warm; it is advisable not to carry them out when it is
still hot, in order to avoid thermal shocks on the cooking plate.
If the appliance is out of use for a long time, it is advisable to turn off the gas tap. Then disconnect
the main electricity supply and wipe all stainless steel surfaces with a cloth soaked in vaseline oil in
order to give it a protective film and air the rooms now and again.
Maintenance
ATTENTION! Before doing any kind of maintenance or repairs, make sure that the
appliance is disconnected from the electric mains and that the gas cutoff valve is closed.
The following maintenance operations must be carried out at least once a year by specialized
personnel. It is advisable to have a maintenance contract.
• Check for correct functioning of all control and safety devices;
• Check for correct ignition of burners and proper functioning at minimum;
• Check the tightness of the gas pipes;
• Check the condition of the power cable;
• Clean the evacuation pipes of type "B" appliances, following the prescriptions in force in the
country of installation;
• The gas tap should be lubricated but this is a difficult operation and not very reliable; therefore
it is advisable to substitute it;
