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. It is recommended not to cool down hard the cooking vat; it should not
undergo thermal shocks due, for example, to the use of ice or extremely cold water.
Otherwise, it is likely that the bottom of cooking vat will crack.
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 any 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 inadvisable 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.
Stainless steel parts should not be exposed to prolonged contact with concentrated acid substances
(e.g. vinegar, condiments, spice mixtures, concentrated kitchen salt...), as they can create chemical
and physical conditions that damage the passivation of the steel. It is therefore advisable to remove
these substances using clean water.
If the appliance is not in use for a long time, it is advisable to turn off the gas tap. Then disconnect
the main electricity supply; wipe all stainless steel surfaces with a cloth soaked in Vaseline oil in
order to give it a protective film; air the rooms now and again.
ATTENTION: Never use substances, detergents and other solutions containing chlorine or its by-
products.
In order to remove any possible scale-marks, do not use products containing salt or sulphuric acid;
suitable products are to be found in the market or, alternatively, a solution diluted in acetic acid can
be used.
While cleaning the appliance, do not use inflammable liquids.
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 cut off valve is closed.
The following maintenance operations must be carried out at least once a year by specialised
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;
