4. MAINTENANCE and CLEANING
Disconnect the appliance from the gas supply before performing any
cleaning or maintenance operations.
At the end of the working day, clean the appliance, both for reasons of
hygiene and to prevent operating faults.
The appliance must never be cleaned with direct or high pressure
jets of water. Moreover, the appliance should not be cleaned with wire
sponges, ordinary steel brushes or scrapers; eventually, and only for the
steel parts, you can use stainless steel wool, wiping the appliance in the
direction of the sheet metal grain.
The top must be cleaned using
hot water and non-chlorine-based
detergents. It must never be cleaned
using steel wool, sandpaper or similar.
If dirtiness is accentuated, the use of
synthetic sponges is recommended
(e.g. Scotchbrite).
For non-stainless steel tops, it is
mandatory to dry the top and protect
it with cooking fat or oil to keep it in
excellent condition and prevent rusting.
If rust should form due to water, humidity and/or failure to protect the
top at the end of cooking, the rust must be removed to prevent corrosion
using stainless steel wool until the oxidised part has been polished. Wash,
dry and protect the top as described previously.
Make sure not to protect the top when wet or damp. In addition to being
pointless, this operation is damaging since rusting will increase under
the layer of protection!
After cleaning, rinse with clean water and dry using a cotton, wool or
linen cloth. Do not use synthetic materials.
All maintenance must be performed by qualified staff.
At least once per year, have the appliance fully checked, including an
assessment of the gas circuit seal and of the components in general.
All routine and special maintenance must be performed by qualified
personnel.
