Maintenance
Gas/Electric
Prior to any operation, disconnect the appliance from the electrical system.
For long-life to the equipment, a general cleaning operation must take place
periodically, bearing in mind the following:
• the glass, steel and/or enamelled parts must be cleaned with suitable non-abrasive or
corrosive products (found on the market). Avoid chlorine-base products (bleach, etc.);
• avoid leaving acid or alkaline substances on the working area (vinegar, salt, lemon
juice, etc.).
• the wall baffle and the small covers (mobile parts of the burner) must be washed
frequently with boiling water and detergent, taking care to remove every possible
encrustation. Dry carefully and check that none of the burner holes is fully or
partially clogged;
• the electrical parts are cleaned with a damp cloth and are lightly greased with
lubricating oil when still warm.
• the stainless steel grids of the working area, after having been heated, take on a
bluish tint which does not deteriorate the quality. To bring colour back to its original
state, use a slightly abrasive product.
N.B.- Cleaning of the taps must be carried out by qualified personnel, who must be
consulted
in case of any functioning anomaly.
Check periodically the state of conservation of the flexible gas feed pipe. In case of
leakage, call immediately the qualified technicians for its replacement.
