information prior to operating.

About the Appliance

Use the cooktop for surface cooking applications such 

as boiling, frying, simmering, steaming and sautéing.

WARNING

The burning of gas cooking fuel can create small 

amounts of carbon monoxide, benzene, 

formaldehyde and soot. To minimize exposure to 

these substances, the burners should be adjusted 

by a certified installer or authorized servicer to 

ensure proper combustion. Ensure proper 

ventilation with an open window or use a ventilation 

fan or hood when cooking with gas. Always operate 

the unit according to the instructions in this manual.

Control Knobs

The cooktop has one control knob for each burner. Push 

in and turn to the left to light and set the desired heat 

setting.

9

WARNING

Failure to operate knobs properly may result in 

personal injury and damage to the appliance.

The cooktop has standard burner controls.

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”.

Turning off a burner

Turn the corresponding control knob clockwise to the 

"off" position.
