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. Be carefull when removing knobs with time control function
(both left knobs). Inside these knobs is interconnection cable, do not try to remove the cable.

Instructions for town (G110, G120, G150.1) and methane gas (G20, G25)
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 rod:
x
anti-clockwise to increase the gas flow
x
clockwise to reduce the gas flow
until a regular minimum flame is obtained.
3. Re-assemble the knob and verify burner flame stability (when quickly rotating the hand
from maximum to minimum position the flame must not shut off).
4. Repeat the operation on all gas taps.
Instructions for liquid gas (LPG: G30, G31)
Tighten the screw on the side of the tap, rod clockwise completely.
Warning: these tasks may only be carried out by a qualified technician, authorized by the gas distributing
company or authorized service center!
