The primary air intake regulator (2) is set with the
reference notch showing “GPL” corresponding te the
secuting screw (3).
The ame is regulated (minimum and maximum) to
suit this type of gas.
If the machine is to be used with a different type
of gas, it will be necessary to replace the injector
in accordance with the above table and to rotate
the primary air regulator (2), which, in the case of
natural gas, will have to be set with the reference
notch showing “N” corresponding to the securing
screw (3).
To do this, it will of course be necessary to loosen
the securing screw (3) and to tighten it again after
rotating the primary air intake regulator (2).
Connections to mains gas, from the gas tap available
in the room to the valve tted on the machine, must
be carried out in accordance with the regulations in
force, using a exible pipe or a rigid pipe in annealed
copper.
In the latter case, the special rubber-pipe tting in
connected tightly to the valve by means of the bico-
nical nozzle and securing nut supplied.
The exible pipe is tted over the end of the mains
outlet and secured with the metal strip supplied.
Alternatively, the annealed copper pipe can be con-
nected up, again using the special biconical nozzle
and the appropriate nuts, directly to the valve.
Once the machine has been connected up to the
gas main, and after lling the boiler up with water in
accordance with the instructions in the booklet (“IN-
STRUCTIONS FOR USE AND MAINTENANCE”),
the burner can be lit in the following manner:
● Open the main gas tap.
● Press on the gas valve knob, on the machine rotate
it 90° anti-clockwise, and keep it pressed in. At
the same time, press the piezoelectric lighter one
or more times – the lighter knob bears a symbol
resembling a spark – until the burner lights up.
14. MACHINES WITH ALTERNATIVE GAS
HEATER VERSION (Fig.14)
N.B. Installation of the machine and any
adjustment or adaptation to the type of gas
should be done by a technically qualied
person.
The machine leaves the factory all set for use with
liquid gas (GPL).
The gas regulator (1) is therefore tted with the ap-
propriate injector shown in the table below:

12. STOPPING THE MACHINE
A - Temporary stop
● Carry out cleaning and maintenance operations.
● Wind up the cable and fasten it to the machine
with sticky tape.
● Cover the machine and place it in a dry room. Do
not leave it exposed to atmospheric agents and
do not allow it to be touched by children or unift
persons.
To disconnect from the main power supply, consult
qualied personnel.
B - Denitive stop
● Besides carrying out the operations necessary for
a temporary stop, cut off the cable, pack the ma-
chine in cardboard, polystyrene or other packing
material and consign it to rms authorized for its
disposal or to second-hand goods dealers.
13. PROBLEMS AND REMEDIES
Check operations to be carried out by the
user with the plug disconnected.
For any type of problem or inconvenience not
specically indicated, disconnect the plug and
contact our service centre without attempting
any direct repairs.
A) The machine does not start:
- check that the plug is connected;
- In case of power failure wait for the power to return
and check if the earth leakage protection circuit
breaker or the main switch is on;
- check the condition of the plug and the supply
cable; if damaged have them replaced by qualied
personnel.
B) There is water under the machine:
- check that the drainage tray is not obstructed.
C) Slow dispensing:
- check that the filters and delivery heads are
clean;
- check that the coffee is not too nely ground.
D) Irregular steam delivery:
- check that the nozzles are not obstructed.
