Adjusting the hob burners' minimum setting:
GB
1. Turn the tap to the minimum position.
2. Remove the knob and adjust the regulatory screw, which
is positioned inside or next to the tap pin, until the flame is
small but steady.
! If the appliance is connected to a liquid gas supply, the
regulatory screw must be fastened as tightly as possible.
3. While the burner is alight, quickly change the position of
the knob from minimum to maximum and vice versa several
times, checking that the flame is not extinguished.
! The hob burners do not require primary air adjustment.
! After adjusting the appliance so it may be used with a
different type of gas, replace the old rating label with a new
one which corresponds to the new type of gas (these labels
are available from Authorised Technical Assistance Centres).
! Should the gas pressure used be different (or vary slightly)
from the recommended pressure, a suitable pressure regulator
must be fitted to the inlet hose in accordance with current
national regulations relating to "regulators for channelled gas".

way when the flame is stable and
even, without killing the flame when
R
the burner is cold or lighting the
nozzle when the burner is hot.
The flow may be adjusted by
loosening the screw "P" and moving the bushing "R" so
that the opening "X" corresponds to the values in the table
below. Once all the adjustments have been made, fasten
the bushing "R" with the screw "P".

Safety Chain
! In order to prevent the appliance from overturning
accidentally, for example in case of a child climbing
onto the oven door, the safety chains MUST be installed!
The cooker is provided with safety chains that must be
fixed with a screw (not supplied as accessory) on the wall
behind the appliance, at the same height as the fixing point
on the appliance.
Make sure that the chains are fixed in the back of the
cooker, as shown in the drawing, in such way to be tight
and parallel to the floor.
! When the installation process is complete, the chains must
be kept in tension!
