3 gr.
The flame 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 (10),
in the case of natural gas.
To do this, it will of course be necessary to loosen
the securing screw (9) and to tighten it again after
rotating the primary air intake regulator (10).
This regulation is anyway to be performed at the
first installation of the machine
Warning: Connections to mains gas,
from the gas tap available in the room
to the rubber-holder hose fitted on the
machine, must be carried out in ac-
cordance with the regulations in force.
Once the machine has been connected up to the
gas main, and after filling the boiler up with water
in accordance with the instructions in this booklet,
the burner can be lit in the following manner:
• Open the main gas tap.
• Press on the gas valve knob (2), on the ma-
chine rotate it 90° anti-clockwise, and keep it
pressed in. At the same time, press the piezo-
electric lighter (3) one or more times until the
burner lights up.
• Wait about 20 seconds, then release the valve
knob and the burner should stay lit (the flame
is visible through the special hole in the panel
behind the dispenser units).
Warning: Should the burner not light
up, do not persist, but release the valve
knob, and then check that lighter spark
on the burner is in order and about 5
mm long.
Should the flame go out when the valve knob is
released, check the position of thermocouple and
the circuit connected to it.
The flame should be bright blue; if not, slightly
regulate the primary air intake (10) until the de-
sired effect is achieved.
Wait until the machine has the correct pressure,
according to instructions. Otherwise, adjust the
gas pressure regulator, which has two regulating
screws.
When the machine is pressurized, check to see
80 130
that the minimum flame is correct by adjusting
the screw (5) if necessary; after loosening the
locking-nut, unscrew the screw until it feels loose
and check whether, under these conditions, the
low flame remains lit, thus acting as a pilot.
If the flame is too high, it will be necessary to
regulate screw (4), turning it slightly clockwise. If,
on the contrary, the flame tends to go out, then
regulate screw (4) by turning it anticlockwise, until
a very low, but constant flame is obtained.
Then rotate the screw (5) clockwise until there is
a high flame, and wait for the boiler to reach the
desired operating pressure; if the flame dies down
before reaching the required pressure, tighten
screw (5) further; if the flame dies down at a high-
er pressure, then unscrew the screw.
Check once or twice by opening the steam tap
to release the pressure in the boiler then hold the
screw (5) still and lock it with the locking-nut.

6 - MAINTENANCE

To allow the proper machine's operation, follow
the maintenance instructions indicated below.

6.1 Safety rules

Do not subject the machine to a water jet. Do not
immerse the machine in water for cleaning.
Disconnect the machine from the power line,
bringing the lever of the omnipolar switch of the
electric system in idle position "0" and close the
water shut-off valve prior to perform maintenance
and/or cleaning operations.
In case of failure of the machine, avoid any type of
repair without assistance and immediately consult
the technical assistance service.
In case the feeder cord is damaged, immediately
switch off the machine, close the water and contact
the technical assistance service. Avoid substituting
it without assistance.
Perform cleaning/maintenance operations when
the machine is cold, preferably wearing protective
gloves for hands.

6.2 Cleaning of machine

Warnings: For the best results and in
compliance with current regulations,
change the water contained in the boil-
er and pipings at every daily startup of
the machine.
