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 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.
