To operate
Select the appropriate control knob, push in and turn
counterclockwise to the desired flame setting. With this
motion, burner sparking and gas flow will be initiated.
Once the flame appears keep the knob pressed in fully
for 2-3 seconds before releasing.
Note: It is normal that sparks will appear at all burners.
Turn off by turning the control knob clockwise to off.
In Case of Power Failure
In the event of a power failure, the burners may be lit by
an alternate flame source. Hold a lit flame source next to
the burner gas exit ports, turn corresponding knob to
max position, and remove flame source immediately
upon burner lighting.
Flame Failure Safety System
Your rangetop is equipped with a safety system that cuts
off the gas flow in case of flame extinguishes by
accident, i.e. because of a strong draft or high amount of
spillage – so preventing an escape of unburned gas.
This systems requires certain burner start procedure, see
above, which means that the knob has to be pressed in
completely for some seconds until the thermocouple at
burner is heated up by flame and keeps the gas flow.
Normal Operation - Electronic Ignition
The cooktop uses electronic igniters to light the burners.
There is no pilot light. Each burner has its own igniter. All
igniters are activated when a control knob is pushed.
9 CAUTION
To avoid possible injury or damage to the
appliance, ensure grates are installed exactly per
installation instructions and not backwards or
upside down.
The igniter should be clean and dry for proper operation.
▯
Avoid getting water or food on the igniter.
▯
If the igniter is wet or soiled, it may spark without
igniting the burner, or even spark continuously when a
flame is present.
Note: If the burner does not light within 4 seconds, turn
the burner off. Check to see that the burner cap is
positioned correctly on the burner base and the igniter is
clean and dry. Wait at least 5 minutes before igniting the
burner again. If a burner still fails to ignite, see “Before
Calling for Service”.
Griddle
To cook most foods on the griddle, the surface must be
pre-heated. The burner power may require adjustment if
the griddle is used for a long time.
Before First Use
Before using your new griddle, wash it in hot, soapy
water, rinse and dry.
Installing the Griddle
