6.3 After-use maintenance
6.3.1 Cleaning
Before cleaning, turn off the appliance, shut off gas supply and electric supply upstream of it.
General information
The main causes for stainless steel wear or corrosion are:
Using abrasive or acid detergents, especially chlorine-based products such as hydrochloric acid or sodium hypochlorite (bleach).
Therefore, before buying a detergent product, make sure it does not corrode stainless steel
Stagnation of ferrous deposits (such as those created by rust dissolved in the water flowing through the piping, especially after the
appliance has remained idle for some time). Therefore, avoid such stagnation; do not use wire wool pads to remove the most
stubborn food residues. Use, rather, pads or spatulas made of stainless steel or softer, non-ferrous materials;
Stagnation of substances having acid components such as vinegar, lemon juice, sauces, salt, etc. Therefore, prevent prolonged
contact of these substances with the stainless steel parts of the appliance. The evaporation of saline solutions over the surfaces of
the appliance is particularly harmful to them.
Routine cleaning
Cleaning the appliance thoroughly every day will keep it in perfect condition and increase its lifetime. Clean the appliance with a damp
cloth using water and soap or detergents, provided that they are not acid or abrasive as discussed further above. Such detergents should
not even be used to wash the floor near the appliance, as their fumes may deposit on the steel surfaces and damage them. Rinse it off
with clean water and wipe it dry with a clean cloth. Do not rub the appliance with steel wool pads as they could leave rust stains. For the
same reason, avoid touching the appliance with ferrous objects.
Never use direct water jets to clean the appliance because this could result in water entering into it and damaging it.
Stains and abrasions on the steel surface
Scratches and dark stains may be smoothed or removed using stainless steel wool pads or synthetic abrasive sponges, which should
always be rubbed in the same direction as the satin finish.

Page 16
Rust
Should you need to eliminate rust stains, contact manufacturers of industrial detergents to find a detergent that can remove such stains.
Industrial descaling products can also be used to that end. After rubbing off the stain and rinsing with clean water, an alkaline detergent
may be required to neutralize any acid compounds left on the surface.
6.3.2 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.
6.3.3 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.
7. Failure Analysis & Troubleshooting
