Rust
If you need to remove rust stains, contact manufacturers of industrial detergents to find a
suitable product. Industrial descaling products can also be used to that end. After using
the descaler and rinsing off the appliance with clean water, an alkaline detergent may be
required to neutralize any acid compounds left on the surface.
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.
Turn off the gas shutoff valve fitted upstream of the appliance.
4.3.3 Periodic maintenance
Only qualified personnel are allowed to carry out service and maintenance operations.
The following maintenance operation should be carried out at least once a year:
• checking for proper operation of all control and safety devices;
• checking combustion, i.e.:
1.
ignition;
2. combustion safety;
3. checking for proper operation throughout the ON-OFF-ON control range;
We recommend signing a service agreement providing for at least one check-up a year.
