• When connecting, the knee R1/2 should be held firmly to prevent it from rotating.
• 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 flat non-metal gaskets
should not be deformed more than by 25 percent.
• To connect the appliance to the gas supply, use a tested and certified flexible hose.
• The flexible connection hose should be able to move freely.
It should not come into contact with the movable parts of the furniture or the bottom
of the cooking hob.
• If an electric oven is built into the kitchen element under the cooking hob, it should
be fitted with a cooling fan.
After connecting the gas hob, check the joints for any leaks.
Gas supply connection plug
A ISO7-1 R1/2 connection plug
B Non-metal gasket with thickness of 2 mm
C Pipe adapter for liquid gas (depending on the model)
Only use pipes and seals in accordance with the Standards. These pipes must
be installed so that, when fully extended, their length does not exceed 2000 mm. For
easier installation and to prevent gas leaks, attach the swivel coupling to the cook
top first, and then to the gas mains pipe. Inverting this sequence may hamper the
gas seal between the pipe and the cook top.
Important: when the installation is complete, check that all couplings are
completely sealed by using a soapy solution. Never use a flame. Also ensure
that the flexible pipe cannot come into contact with any moving part of the
cook top (e.g. drawer) and that it is not in a position where it could be
damaged.
After the connection, check the burners for correct operation.
The flames must be clearly visible, and should be blue and green at the center. If the
flame is unstable, increase the minimum power.
Adaptation to a different
type of gas
• 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 and supplied provided (see table below).
• After finishing this sequence, replace the old setting label with the new one
provided for the new injectors.
Adjustment elements
To leave the adjustment elements accessible, please observe the following
instructions:
• Remove the support grid and burner covers with respective crowns.
• In double burners, adjustment elements are accessible behind the main nozzle
protective plate.
• Remove the control knobs, including the gaskets.

1. Light the burner and bring it to the minimum position.
2. Remove the gas tap knob and turn the adjustment screw on the side of the tap
