3. Position the appliance level, adjusting the feet of the cooker.
4. Connect mains pipe to machine pipe (fig.1) using a mechanical filter and an interception cock.
5. Connect machine outlet pipe (fig. 1) to a suitable manifold that withstands high temperatures.
2.4 Connecting to the gas supply mains
Before connecting up the gas consult the gas board, all the installation and maintenance
operations should be carried out by the gas board or by authorized fitters.
Make sure the
data of the rating plate correspond to the mains values. The rating plate is located at the bottom
of the screen-door panel.
Having verified that the gas supply system available is adequate you can go ahead with the
connection:
1. connect the mains pipe to the machine pipe (pos. G in fig.1) using a quick closing interception
cock which is easy to reach.
You must use a pressure regulator to set the manifold
pressure as in tab. 4.1
2. Go ahead with setting up and adjusting as described in paragraph 2.4.1
3. Make all the checks listed below.
2.4.1 Setting up and adjusting
The first operation to carry out is to check the supply pressure, proceeding as follows:
1. Make sure the gas supply has been cut off.
2. Open the front door, unscrew the closing screw (pos. 9 in fig.6) of the pressure socket of the
supply pipe (pos. 1 in fig.6)
3. Connect a pressure gauge to the socket (e.g. a manometer)
4. Open the gas interception cock and measure the value of the supply pressure.
5.
CAUTION: If the value of the supply pressure measured lies outside the interval shown in
table 2.2, it is not possible to go ahead with installation and it is necessary to inform the
gas board of the anomaly with the mains.
6. Close the gas interception cock, disconnect the pressure gauge, screw the closing screw back
on and close the front door.

Tab. 2.2 Permissible limits for the gas supply pressure
After checking the supply pressure it is necessary to adjust the pressure at the nozzle, proceeding
as described below:
1. Make sure the gas supply has been cut off.
2. Take off the door by unscrewing the screw fixing it to the support.
3. Remove the water loading knob (1 di fig. 3) and unscrew the two screws fixing the instrument
panel to the under-panel. Remove the instrument panel taking care over the wire of the igniter.
4. Open the gas interception cock and ignite the burner flame by following the instructions of par.
5.2 positioning the knob onto the maximum position.
5. Adjuste the pressure regulator since the manifold pressure is 4” W.C.
6. Operate the appliance in the maximum conditions for at least 15 minutes, and then turn the
knob onto the minimum position.
7. Turn the minimum adjustment screw (pos. a in fig. 7) to obtain a reduced flame but sufficiently
stable and homogeneous.
8. Turn off the burner by following the instructions of par. 5.2, close the gas interception cock,
disconnect the pressure gauge, screw the closing screw back on and refit the instrument panel
and the front door.
2.4.2 Checks
For the purposes of operating safety it is essential to make the following checks:
∗
Checking air-tightness:
Check there are no leaks in gas pipe using a solution of soap-water.
