the washer will be stuck to the lower face of
the glass.
Silicone should not be applied between
the glass and the unit worktop because
if it becomes necessary to remove the
cooker from its position, the glass could
break when trying to detach it.
Position the clips as shown in the diagram,
fastening them to the openings in the
lower part of the body using the metal thre-
aded screws provided (Ø 4,2 mm).
For worktop thicknesses of 30 mm. or less,
use the self-tapping screws (M5) that are
provided as a fastening accessory - put
them into the clip’s round hole. This hole
will be threaded as the screw is inserted
into it, and this should be done before
fixing the clip to the worktop.
The clips and the sealing washer are pro-
vided, and can be found in the packaging.
Connecting the gas
Model VT DUAL.1
Connecting the hob to the gas mains
should be done in compliance with the
current installation standards and/or regu-
lations.
Ventilation slots should also be made at
the site in compliance with current norms.
The hob is provided with a threaded con-
nection 1/2” in diameter, in line with ISO
228-1. A Ø 10/12 mm. copper pipe is pro-
vided as an accessory for welding the gas
inlet pipe.
Whenever the gas connection nut is remo-
ved, its washer should be changed.
In order that the hob is not damaged by
tightening the nut on the gas connection
pipe, a maximum torque of 300 Kgf * cm
should be applied.
When the gas connection has been made,
the installation should be checked to ensu-
re that it is completely sealed. If the check
is done using air, care should be taken that
the test pressure is no more than 200
g./cm

. Where air is not available, soapy
water should be applied to ensure that
there are no leaks in the connections.
Tes-
ting should never be done using a
flame.
When the hob has been installed, check
that the burner minimums are properly
adjusted. To do this, light the burners and
check that they do not go out if you switch
quickly from the maximum to the mini-
mum.
