on the label situated on the actual hob. If the gas supply is different
from the type for which the appliance has been set, replace the
corresponding nozzles (provided), following the instructions given
in the paragraph "Adaptation to different types of gas".
• For trouble-free operation, suitable use of energy and a longer life
cycle for the appliance, make sure that the supply pressure
complies with the values indicated in table 1 "Burner and nozzle
specifications", otherwise install a special pressure regulator on
the supply pipe in compliance with current standards and
regulations.
• Connect in such a way that the appliance is subjected to no strain
whatsoever.
Either a rigid metal pipe with fittings (fig. 8-D) in compliance with
norms must be used for connecting to the nipple union (threaded -
cylindrical ½"G fitting "F") situated at the rear of the appliance (fig.
8), or a flexible steel pipe with a continuous wall and fittings (fig. 8-
C) in compliance with norms, which must not exceed 2000 mm in
length. Check that the connecting pipe cannot come into contact
with moving parts which could damage or crush it. For installation
with a flexible rubber pipe, apply the special hose support for liquid
gas (fig. 8-A) or natural gas (fig. 8-B). The gasket "G" (provided)
must be utilised in every type of connection. The two ends of the
pipe must be fastened with the purpose designed pipe collars "E",
in compliance with the norms. The flexible pipe should comply with
the norms, and be specific for the type of gas used. In addition:
•
it should be as short as possible, with a maximum length of 1.5
metres;
•
it should not be bent or kinked;
•
it should not be in contact with the rear panel of the appliance or
in any case with parts which may reach a temperature of 50°;
•
it should not pass through holes or slits used for discharging the
oven flue gases;
•
it should not come into contact with pointed parts or sharp cor-
ners;
•
it should be easy to inspect along its entire length in order to be
able to check its condition;
•
it should be replaced before the date printed on the actual pipe.
Important: A pressure regulator, in compliance with the
applicable norm in force, must be inserted when connecting
to a liquid gas supply (in a cylinder).
Upon completion of installation, check for leaks from the gas circuit
using a soapy solution (never use a flame). Make sure that the
natural gas pipe is adequate for a sufficient supply to the appliance
when all the burners are lit.
Adapting to different types of gas (instructions for the hob)
To adapt the hob to a different type of gas from the factory-set one
(indicated on the rating plate at the top of the hood or on the
packaging), the burner nozzles should be replaced as follows:
• Remove the hob grids and slide the burners off their seats.
• Unscrew the nozzles (fig. 9), using a 7 mm socket spanner and
replace them with nozzles for the new type of gas (see table 1
"Burner and nozzle characteristics").
Reassemble the parts following the above procedure in the re-
verse order.
• On completing the operation, replace the old rating label with the
one showing the new type of gas; the sticker is available from our
Service Centres.
INSTALLATION
Replacing the independent "double flame" burner nozzles:
•
Remove the grids and slide the burners off their seats. The
burner is made up of three separate parts (see Fig. C and Fig.
D);
•
Unscrew the nozzles using a 7 mm socket spanner. The inner
burner has one nozzle, while the outer one has two (of the same
size). Replace the nozzles with those for the new type of gas
(see table 1).
•
Replace all the parts, following the steps described above in the
reverse order.

Adjusting the primary air of the burners
The primary air of the burners does not need to be adjusted.
Adjusting the low flame
• Turn the tap to the low flame position;
• Remove the knob and turn the adjusting screw, situated to the
right of the tap (fig. 10) until you obtain a regular small flame,
using a screwdriver (loosening the screw increases the height
of the flame, tightening decreases it).
N.B.: In the case of liquid gas, the regulation screw must be
screwed in all the way.
•
Having obtained the low flame setting required and with the
burner lit, abruptly change the position of the knob several times
from minimum to maximum and vice versa and check that the
flame does not go out.
•
In appliances fitted with the safety device (thermocouple), should
the device fail to work with the burners set to the low flame
setting, increase the low flame setting of the same on the ad-
justing screw.
Once the adjustment has been made, remount the seals on the by-
passes using sealing wax or similar.
Adapting to different types of gas (instructions for the oven)
In order to adapt the oven to a different type of gas with respect to
the gas for which it was manufactured (indicated on the label), follow
these simple steps:
a) Replacing the oven burner nozzle:
·
open the oven door fully;
·
pull out the sliding oven bottom;
·
unscrew the burner fastening screws;
·
remove screw "V" and then the oven burner;
