9.2.1 Ignition plugs and safety devices
For good functioning of the lighting ignition plugs and the safety devices,
keep them very clean.
Check frequently and clean with a damp cloth when necessary.
9.2.2 The cover
Clean the glass or steel cover, where mounted, with warm water. Never
use abrasive sponges or detergents. To clean the rear part of the
cooktop, remove the cover by lifting out.
When finished cleaning, refit the cover making sure to insert it correctly.
Before lifting up the cover, dry out properly.
Never lower the cover when burners or electric elements are on or
still hot.
9.3 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 after every use 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 (at least
every 2 years). Each time the cooker is moved the connection may be
stressed: test it for leakages using special sprays or a solution of soap and
water.
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.
