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.
CAUTION
9
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
The griddle is customized to fit only on the grates
illustrated below.
WARNING
9
Place and remove the griddle only when all grates
and the griddle have cooled down and all burners
are off.
Typical flame characteristics
The burner flame should be blue in color and stable with
no yellow tips, excessive noise or fluttering. It should
burn completely around the burner cap.
Checking the flame characteristics:
Yellow flames:
Further adjustment is required.
Yellow tips on outer cones:
Normal for propane gas.
Soft blue flames:
Normal for natural gas.
Orange flames:
Can be normal if certain types of
humidifiers are used in the
home. Flames should return to
blue without the humidifier run-
ning.
