Instructions for the user

13.5 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

Oven gasket: with time the oven gasket may harden and crack on the surface, resulting in leakage of heat from the oven and higher temperatures on the control panel and knobs. Check it periodically (once a year) and replace it if necessary.
