use of a gas cooking appliance produces heat and moisture in the room in which it is installed.
The room must therefore be well ventilated.
Intensive and lengthy use of the appliance may require additional ventilation. This can be
achieved by opening a window or by increasing the power of the mechanical exhausting system if
installed.

WARNING!

NEVER use this appliance as a space heater
to heat or warm the room. Doing so may result
in carb o n mono x i de po i so n in g and
overheating ot the oven.

CLEANING

CAUTION:
before cleaning the appliance, disconnect it
from the gas and electricity supplies.

3) WORKTOP

If you wish to maintain the shine of the ceramic
surface, treat the glass with a silicon-based film
product before use to protect the surface against
water and dirt. This protective film is not durable,
so it is advisable to repeat the application of the
product frequently.
It is very important to clean the hob every time you
use it, while the glass is still warm.
Do not clean using abrasive metal scourers, powder
abrasives or corrosive sprays.
Depending on the degree of dirt, we recommend:

- for light stains, a damp sponge is sufficient.

- Tough, encrusted dirt is easily eliminated using a
scraper (fig. 3), not supplied with the hob, but
easy to find in local stores. Use the scraper

carefully to avoid damaging the hob.

- Traces of liquid spilled from pans ca n be
eliminated with vinegar or lemon juice.

- Never allow sugar or sugary foods to fall on the
hob while cooking. Should this occur, switch off
the hob and clean it immediately with hot water,
using a scraper on hot spills.

- As time goes by metallic reflections, colouring or
scratches may appear due to poor cleaning and
the incorrect movement of pans. Scratches are
hard to eliminate but do not affect the correct
operation of your hob.

- Do not use jets of steam to clean the appliance.
