• For sealing of the connection joints, use a non-metal approved
gaskets and approved sealants.
• The gaskets should only be used once. The thickness of the
fl at non-metal gaskets should not be deformed more than by
25 percent.
• To connect the appliance to the gas supply, use a tested and
certifi ed fl exible hose.
• The fl exible connection hose should be able to move freely.
It should not come into contact with the movable parts of the
kitchen furniture (e.g. a drawer), or the bottom of the cooking hob.
• If an electric oven is built into the kitchen element under the
cooking hob, it should be fi tted with a cooling fan, and the
connection should be made using a pipe completely made of
metal (e.g. a stainless steel fl exible pipe.
After connecting the gas hob, check the joints for any
leaks.

• The procedure or adaptation of the cooker to another type
of gas does not require removal of the appliance from the
worktop.
• Before adapting, disconnect the appliance from the power
mains and close the gas supply valve.
• Replace the existing nozzles for nominal thermal load with
corresponding nozzles for the new gas type (see table below).
• When adapting the appliance to liquid gas, fasten the
regulation screw for minimum thermal load as far as it will go,
in order to attain minimum thermal load.
• When adapting the appliance to natural gas, release the
minimum thermal load regulation screw in order to attain
minimum thermal load, but do not rotate it by more than 1.5 turns.
