Gas Connection - SCHOLTES PPF 20DC 120 Mode D'emploi

Gas connection

• Check that the appliance is set for the type of gas
available and then connect it to the mains gas
piping or the gas cylinder in compliance with
current regulations and standards.
• This appliance is designed and set to work with the
gas indicated on the label situated on the actual
hob. If the gas supply is other than the type for
which the appliance has been set, proceed with
replacing the corresponding nozzles (provided),
following instructions given in the paragraph
"Adaptation to different types of gas".
• For trouble-free operation, suitable use of energy
and longer life of the appliance, make sure that the
supply pressure complies with the values indicated
in the table 1 "burners and nozzles 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 in compliance
with the standards in force must be used for
connecting to the nipple union (threaded ½"G male
fitting) situated at the rear of the appliance to the
right (Fig.5), or flexible steel pipe in compliance with
the standards in force, which must not exceed 2000
mm in length. Should it be necessary to turn the
fitting, the gasket (supplied with the appliance) must
be replaced. Upon completion of installation, check
the gas circuit, the internal connections and the taps
for leaks using a soapy solution (never a flame). Also
check that the connecting pipe cannot come into
contact with moving parts which could damage or
crush it. Make sure that the natural gas pipe is
adequate for a sufficient supply to the appliance
when all the burners are lit
Important: Important:
Important: Important: A pressure regulator, in compliance with Important:
the standards in force, must be inserted when
connecting to a liquid gas supply (in a cylinder).
Adapting to different types of gas
To adapt the hob to a different type of gas other than
default type (indicated on the rating plate at the base of the
hob or on the packaging), the burner nozzles should be
replaced as follows:
1. Remove the hob grids and slide the burners off their
seats.
2. Unscrew the nozzles using a 7 mm socket spanner
(fig.6), and replace them with nozzles for the new type
of gas (see table 1 "Burner and nozzle characteristics").
3. Reassemble the parts following the above procedure in
the reverse order.
4. Once this procedure is finished, replace the old rating
sticker with one indicating the new type of gas used.
Sticker are available from any of our Service Centres.
Replacing the nozzles on separate "double flame " burners:
1. remove the grids and slide the burners from their
housings. The burner consists of 2 separate parts (see
figure);
2. unscrew the burers with a 7 mm wrench spanner. The
internal burner has a nozzle, the external burner has two
(of the same size). Replace the nozzle with models
suited to the new type of gas (see table 1).
3. replace all the components by repeating the steps in
reverse order
• Adjusting the burners' primary air :
Does not require adjusting.
• Setting the burners to minimum:
1. Turn the tap to the low flame position.
2. Remove the knob (fig.7)and adjust the adjustment
screw, which is positioned in or next to the tap pin, until
the flame is small but steady.
3. Having adjusted the flame to the required low setting,
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 does not go out.
4. Some appliances have a safety device (thermocouple)
fitted. If the device fails to work when the burners are
set to the low flame setting, increase this low flame
setting using the adjusting screw.
5. Once the adjustment has been made, replace the seals
on the by-passes using sealing wax or a similar substance.
