4.3.2 Idle period
If the appliance will remain idle for a certain period of time, clean it and wipe it dry first,
and then apply a film of a suitable product (such as vaseline oil spray or similar products)
to protect it. Shut off gas and power supply upstream of the appliance.
To avoid the appearance of corrosion spots, make sure that any salt residues left on the
internal and external walls are carefully removed.
4.3.3 Periodic maintenance
Only qualified personnel are allowed to carry out service and maintenance operations.
The following maintenance operations should be performed at least once a year:
• checking for proper operation of all control and safety devices;
• checking burner combustion, i.e.:
1. ignition;
2. combustion safety;
3. checking for proper operation throughout the entire HIGH-to-LOW control
range.
We recommend signing a service agreement providing for at least one check-up a year.
