8.2.2 The electric element
After use, to make sure that the surfaces are clean and long lasting, the
electric element must be treated with specific cleaning products which
are available on the market. This necessary operation prevents
oxidisation (rust formation).
8.2.3 The cover
Clean the glass or steel cover, where mounted, with warm water. Never
use abrasive sponges or detergents.
Never lower the cover when burners or electric elements are on or
still hot.
8.3 Preventive maintenance
This appliance does not need any special maintenance. However, a
few
simple operations have to be carried out periodically to prevent
malfunctioning:
Burners: the burners must be cleaned periodically to ensure correct
combustion; make sure that all the openings and flame ports are clean
and free of obstacles, and that the burners rest firmly on their supports.
Gas connection: the gas connection must be checked periodically.
Flexible pipes: if a flexible pipe is used, it must be inspected
periodically (once a year) for leakages: if the surface of the pipe
appears rigid and cracked, disconnect immediately the cooker from the
gas supply and replace the pipe with a new one.
Valves: if the gas valves get stuck or hard to turn, they need to be
cleaned and re-greased; this operation must be carried out by an
authorised person.
