CAUTION: The gas supply shall be shut off prior to disconnecting the electrical power, before proceeding with the
conversion. The kit for the gas conversion of the burners is relevant to the model of the appliance indicated on the
label sti-cking to the first page of this booklet. The kit contains the number and type of orifices necessary for the
conversion, all the necessary instructions, a label to stick onto the old one to show the new setting (see table 2) and
the label to be completed by the technician who performs the conversion. The appliance is pre-adjusted in factory
for the gas indicated on the label put on the gas inlet pipe. For the conversion to another gas refer to table 3.

The positions, types of burner and relevant orifices for the models included in this booklet are depicted in table 3.
The only operation to perform after conversion to a gas different from that shown on the rating plate/label is the
adjustment of the minimum gas flow. (See page 3 of this leaflet). After conversion remember to put the new gas
indication label (supplied in the conversion kit) as close as possible to the existing rating plate, then check the
regular ignition of the burners (see pages 3 and 4 of this leaflet, “Lighting the burners”).

If the appliance is installed at an altitude exceeding 2,000 ft, a new set of orifices can be requested from the
supplier or an authorised service parts distributor.

NOTE: Due to the lower atmospheric pressure at higher altitudes, foods tend to take longer to cook. Therefore,
recipe adjustments should be made in some cases. In general, no recipe adjustment is necessary for yeast-risen
baked goods, although allowing the dough or batter to rise twice before the final pan rising develops a better
flavor. Try making the adjustments below for successful recipes. Take note of the changes that work best and mark
your recipesaccordingly. You may also consult a cookbook on highaltitude cooking for specific recommendations.

WARNING: after first installation of the appliance, after gas conversion kit installation or after any service
intervention concerning main gas parts of the appliance, make the leak test using water with soap on the gas
connections in order to verify the correct installation. Do not use fire for gas leak testing. The test is valid if there is no
bubble or foam build-up during a period of one minute.

ADJUSTING THE MINIMUM GAS FLOW

When installing the cooker you must check that the minimum gas flow of the burners on is correctly regulated. If the
type of gas is changed it is indispensable to adjust the minimum flow. The adjustment procedure is as follows.

Burners on the hob (g. 13)

1. Light one burner at a time and turn the flame up to maximum

2. Remove the knob of the corresponding gas tap and insert screwdriver in the screw as shown in figure 14a

or 14b (DUAL).

3. Turn the tap to minimum position.

4. Unscrew, turning to the left, to increase the flame, or screw to the right to decrease it

5. If a liquid gas is used (Butane - Propane), the regulating screw must be fully screwed in

LIGHTING THE BURNERS

The index above the knobs will help you to find the corresponding burner. Press the knob by turning it
counterclockwise and bring it to the ignition position; keep the knob pressed for about 5 seconds so that upon its
release the flame remains alight. In case of unsuccessful ignition wait 5 minutes before relighting and repeat the
operation.

ADJUSTMENT OF THE PRESSURE REGULATOR FOR USE WITH DIFFERENT TYPE OF GAS

The pressure regulator supplied with the appliance is a convertible type pressure regulator for use with Natural
Gas at a nominal outlet pressure of 5”w.c. or Propane at a nominal outlet pressure of 10”w.c. and it is pre­arranged from the factory to operate with one of these gas/pressure as indicated in the pre-arranging labels
affixed on the appliance, package and Instruction booklet.

If Natural gas is converted to Propane, also the by-pass orifice has to be changed.
The regulating screw of the by-pass orifice must be fully screwed in.

To convert the regulator (Fig.6 and Fig.7) for use with the other gas (different from the one for which it is pre-arran­ged) it is enough perform the following operations:

1. Unscrew by hand the upper metal stopper of the regulator.

2. Unscrew by hand the white plastic piece screwed under the above mentioned metal stopper, afterward screw
it again in opposite way under the metal stopper(for gas reference see the written “Propane” and “NAT” with
relative indicating arrows on the white piece).

3. Screw again by hand the metal stopper in the original position on the regulator. Operating in this way the gas
regulator is converted for use with the other gas/pressure
