4.1 Before using the appliance
4.1.1 Preparing the appliance for use
Prior to cooking for the first time, we recommend that you clean the appliance, and espe-
cially the cooking pan, very thoroughly. Remove all packing materials and adhesive films
from the appliance very carefully. Before cleaning the stainless steel parts, make sure that
the detergent you intend to use does not contain any abrasive substances and that it is suit-
able for stainless steel surfaces. Wipe the appliance dry with a clean cloth.
Never use water jets to clean the appliance.

4.2 Using the appliance
4.2.1 Lighting the pilot flame
Turn the knob (item 14 in Fig. 1) to the left until the power indicator light (item 17 in Fig.
1) lights up.
Exercise a slight pressure on the push-button shown as item 13 in Fig. 1 and turn it to the
"spark" position shown as item 21 in Fig. 2. Then, press and hold down the same push-
button so that the pilot flame lights and check for proper lighting through the inspection
hole (item 12 in Fig. 1) especially provided.
Hold down the push button for about 15-20 seconds to allow the thermocouple to heat. If
the pilot flame goes out, repeat the lighting process.

4.2.2 Lighting the main burner
If you turn the knob (item 14 in Fig. 1) further, the pan will start heating. Heating is pro-
vided by tubular stainless steel burners capable of withstanding mechanical and thermal
stress.
Figure 3 illustrates knob positions.
Pan bottom temperature can be selected between 50°C/122°F (item 31) and 300°C/572°F
(item 32).

4.2.3 Cooking
• Use the thermostat to set the desired cooking temperature
• Spread some oil or fat smoothly on the pan.
• Put products on the pan when the set temperature has been reached.
• When the under side of the product has reached the doneness desired, turn it over
and cook the other side.
• When both sides have been cooked, reduce the temperature and leave the products
on the pan until done.
Never leave the appliance unattended while in use.
4.2.4 Switching off the appliance
To turn off the main burner, turn the knob towards the left to the position shown as item
30 in Fig. 3: only the pilot flame will remain lit. Exercise a slight pressure and turn the
push button (item 13 in Fig. 1) to the position shown as item 20 in Fig. 2 to extinguish the
pilot flame too.

4.2.5 Emptying the pan
The utmost attention should be given to this operation, which should be carried out only
after the liquid contained in the pan has cooled down.
This appliance is equipped with an automatic system that shuts off gas supply to the main
burners if the pan is tilted while in operation.
Manual tilt bratt pans
• Turn off the appliance as described in the previous paragraph.
• Turn the handwheel (item 40 in Fig. 4) clockwise.
• The pan will start tilting up to the desired position or the end-of-stroke position.
• Turn the handwheel anti-clockwise to bring the pan back to horizontal position.

14 in Fig. 1) to the left until the power indicator light (item 17 in Fig. 1) lights up.
• Press the push-button (item 35 in Fig. 4) to tilt the pan.
• The pan will start tilting up to the desired position or the end-of-stroke position.
• Press the push-button (item 36 in Fig. 4) to bring the pan back to horizontal posi-
tion.

4.3 After-use care
4.3.1 Cleaning
Before cleaning, turn off the appliance and shut off gas supply upstream of it.
Wait until the appliance has cooled down before you start cleaning it.
General information
The main causes for stainless steel wear or corrosion are:
• using abrasive or acid detergents, especially chlorine-based products such as hy-
drochloric acid or sodium hypochlorite (bleach). Therefore, before buying a deter-
gent product, make sure it does not corrode stainless steel (see also paragraph
"Routine cleaning");
• 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 scourers to remove
the most stubborn food residues. Use, rather, scourers 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. Avoid prolonged contact of the stainless steel parts of the appli-
ance with those substances. The evaporation of saline solutions over the surfaces
of the appliance is particularly harmful to them.
Routine cleaning
Cleaning the appliance thoroughly on a daily basis is the key to keeping it in perfect work-
ing condition and prolonging its life. 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. If the appliance is very
dirty, use a synthetic Scotch BriteTM type sponge. Rinse it off with clean water and wipe
it dry with a clean cloth. Do not rub the appliance with wire scourers 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 enter-
ing into it and damaging it.
Stains and abrasions on the steel surface
Scratches and dark stains may be smoothed or removed using stainless stainless steel
scourers or synthetic abrasive sponges, which should always be rubbed in the same direc-
tion as the satin finish.

3.2.2004 Rev. 1.1
Operating instructions

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 both power supply and the gas shut-off valve upstream of the appliance.
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 combustion, i.e.:
1. ignition;
2. combustion safety;
3. checking for proper operation throughout the ON-OFF-ON control range;
• lubricating all pan tilting mechanisms.
We recommend that you sign a service agreement providing for at least one check-up a
year.
