6.4 Lighting and shutdown of electric oven GN 1/1 

With knob (pos. 1 fig. 5A) turn the thermostat from the “0” position
to a desired temperature between 50°C and 300°C; the indicator
light will come on; the green one (pos. 2 fig. 5A) shows that the
appliance is on, the yellow one (pos. 3 fig. 5A) indicates that the
heating elements are operational, as soon as the set-up temperature
is reached, the indicator light goes off.

To turn the appliance off, turn the knob to position “0”.

6.5 Lighting and shutdown of gas oven GN 2/1

6.5.1 Lighting the pilot gas oven GN 2/1

6.6 Turning the appliance off in case of
breakdown

6.6.1 What to do in case of failure 

In case of breakdown or malfunctioning or failure close the gas cock
and the oven. Close the connecting cock of the unit and switch off
any electric power. Call the service centre.

6.6.2 What to do in case of prolonged period of disuse

When the appliance is not to be used for a long time, clean thor-
oughly, cas instructed in the chapter 6.7 “Appliance care and fre-
quency of maintenance”, close the connecting cock of the unit and
switch off any electric power.

6.7 Appliance care and frequency of maintenance

Attention! When cleaning, carefully avoid washing the
appliance with direct water jets or high-pressure
water!

Cleaning must be performed when the appliance is cold.

Thorough daily cleaning of the appliance, after disconnecting it, will
keep it in perfect working order and make it last longer. All steel
parts should be cleaned with water and a detergent, using a damp
cloth; do not use abrasive substances or corroding detergents.

Do not use steel wool, which could cause rust to form.

For the same reason, avoid touching the appliance with anything
made of iron. Do not clean with sandpaper and lubricating gel paper.

If absolutely necessary, you may use pumice powder.

If the appliance is extremely dirty, use a synthetic sponge (i.e.
Scotchbrite sponge).

After cleaning the appliance, rinse with clean water and wipe with
a clean cloth.

If the main burner needs cleaning, proceed as follows:

•  Remove the pan support, cover, rings and burner crown;

•  Clean burner parts with water, soap and a suitable tool, then

rinse and wipe;

•  When reassembling the parts, make sure you place them back in

the right position.

All maintenance and repair work must be carried out by authorized
technicians only.

The appliance must be checked at least once a year. For this reason,
a service agreement contract is recommended.

6.8 Recommendations for the treatment of 
stainless “steel industrial” kitchens

6.8.1 Useful information on “stainless steel”

Industrial kitchens are generally made of “stainless steel” having
the following material codes:

•  1.4016 or 1.4511 = magnetizable chromed steels

•  1.4301, 1.4401 and 1.4571 =  non-magnetizable chromed steels

Chromed steels have favourable thermo-technical characteristics. In
