COOKTOP USE
Read the instructions before installing or using this appliance.
1. This appliance shall be installed in accordance with the regulations in
force and only used in a well-ventilated space.
2. The use of a gas-cooking appliance results in the production of heat and
moisture in the room in which it is installed. Ensure that the kitchen is well
ventilated: keep natural ventilation holes open or install a mechanical
ventilation device (mechanical extractor hood).
3. Prolonged intensive use of the appliance may call for additional
ventilation, for example opening of a window, or more effective
ventilation, for example increasing the level of mechanical ventilation
where present.
IGNITION AND OPERATION OF THE BURNERS
To ignite a burner, push down on the burner knob and rotate it
counterclockwise until the knob indicator is aligned with the ignite icon.
Release the knob and adjust the flame intensity by further rotating the knob
counterclockwise from MAX (maximum) to MIN (minimum).
NOTE: For models with a flame failure safety device - Once the flame is lit,
hold the knob depressed for about 3-4 seconds until the device keeps the
burner automatically lit. If the burner fails to ignite, wait one minute for the
gas to dissipate before attempting to reignite.
To turn off the burner, rotate the knob clockwise until the indicator on the
knob is aligned with OFF.
POWER FAILURE
In case of prolonged power failure, the surface burners can be lit manually.
Hold a lit match near a burner and turn knob counterclockwise until the
indicator is aligned with MAX. After the burner is lit, turn knob to desired
setting.
In the case of unintentional flame extinguishing, the safety valve intervenes
by shutting off the gas to the burners.
The electric igniter must not be actuated for longer than 15 seconds. Should
the burner not light, or should the burner be unintentionally turned off,
immediately close the burner, and wait at least 1 minute before repeating.
Once ignited, adjust the flame as desired.

FLAME TOO LARGE
FOR PAN SIZE
USE LIDS THAT
FIT PROPERLY
For lower gas consumption and a better result, use saucepans with a
diameter matching the diameter of the burner, to avoid the flame coming up
around the sides of the saucepan. See the Container Table. Use only flat-
bottomed pans.
As soon as liquid starts to boil, turn the flame down to a level sufficient to
maintain boiling.
COOKWARE
MATCH PAN DIAMETER TO FLAME SIZE
The flame should be the same size as the bottom of the pan or smaller. Do not
use small pans with high flame settings as the flames can lick up the sides of
the pan. Oversized pans that span two burners are placed front to rear, not
side to side.
USE BALANCED PANS
Pans must sit level on the cooktop grate without rocking. Center the pan over
the burner.
USE A LID THAT FITS PROPERLY
A well-fitting lid helps shorten the cooking time. Flat, heavy bottom pans
provide even heat and stability.
