Gas Connection to Flexible Steel Pipe
The gas feed connector to the appliance is a threaded, male 1/
2" connector for round gas pipe. Only use pipes, tubes and
gaskets that comply with current safety codes. The maximum
length of the flexible pipes must not exceed 2000 mm. Once the
connection has been made, ensure that the flexible metal tube
does not touch any moving parts and is not crushed.
Check the Seal
Once the appliance has been installed, make sure all the
connections are properly sealed, using a soapy water solution.
Never use a flame.
Electrical Connection
The cooktops fitted with a tripolar electrical supply cord are
designed to be be used with alternating current according to the
indications on the rating plate located under the cooktop. The
earthing wire can be identified by its yellow-green colour.
In the case of installation over a built-in electric oven, the
electrical connections for the cooktop and oven should be
independent, not only for safety purposes, but also to facilitate
removal of one or both in the future.
Electrical Connection for Gas Cooktop
Fit the supply cord with a standard plug for the demand rate
indicated on the rating plate or connect it directly to the electrical
mains. In the latter case, a single pole switch must be placed
between the appliance and the mains, with a minimum opening
between the contacts of 3 mm in compliance with current safety
codes (the earthing wire must not be interrupted by the switch).
The power supply cord must be positioned so that it does not
reach a temperature in excess of 50°C above room temperatu-
re at any point.
Before making the actual connection, make sure that:
•
The fuse and electrical system can withstand the load
required by the appliance;
•
That the electrical supply system is equiped with an efficient
earth hook-up according to the norms and regulations
prescribed by law;
•
That the plug or switch is easily accessible.
Important: the wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow
- Earth
Blue
- Neutral
Brown
- Live
As the colours of the wires in the mains lead may not correspond
with the coloured markings identifying the terminals in your plug,
proceed as follows:
Connect the Green & Yellow wire to the terminal marked “E” or
or coloured Green or Green & Yellow.
Connect the Brown wire to the terminal marked “L” or coloured
Red.
Connect the Blue wire to the terminal marked “N” or coloured
Black.
Adapting the Cooktop for Different Types of Gas
To adapt the cooktop to a different type of gas than that for which
it was designed, (see the sticker under the hob or on the
packaging), the burner nozzles must be changed, as follows:
•
Remove the pan supports and slide the burners out of the
cooktop.
•
Unscrew the nozzles using a 7mm socket wrench and
replace them with those for the new type of gas. (See table 1,
“Burner and Nozzle Specifications”).
•
Reassemble the parts following the instructions in reverse
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.
If the gas pressure is different than that prescribed, a pressure
regulator must be installed at the source, in compliance with
national standards governing the use of piped gas regulators.
Replacing the nozzles on separate “double flame “
burners:
•
remove the grids and slide the burners from their
housings. The burner consists of 2 separate parts (Fig.
C and fig. D);
•
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).
•
replace all the components by repeating the steps in
reverse order.

Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
Minimum Regulation
•
Turn the gas valve to minimum.
•
Remove the knob and turn the regulator screw (positioned
either on the side of the top or inside the shaft) clockwise
until the flame becomes small but regular.
N.B.: In the case of liquid gas, the regulation screw must be fully
screwed in (clockwise).
•
Make sure that, when the knob is turned rapidly high to low,
the flame does not go out.
•
In the event of a malfunction on appliances with the security
device (thermocouple) when the gas supply is set at
minimum, increase the minimum supply levels using the
regulator screw.
Once the adjustment has been made, apply sealing wax, or a
suitable substitute, to the old seals on the by-pass.
