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, loosen the set screw (9) and then make
moving forward or backward the primary air reg-
ulator. (10).
After making the adjustment, tighten the set screw
(9).
The air adjustment is however to be performed at
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
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 expose the machine at water jets. Do not
submerge the appliance in water in order to per-
form cleaning.
In case of malfunction, avoid every kind of repair
attempt made by yourself and immediately consult
the technical assistance.
In case of damage to the electrical cable abso-
lutely to change by yourself, instead of it perform
every securing operation for the machine and call
the technical assistance service.
Securing operations:
For maintenance and/or malfunctioning and
cleaning put the omnipolar switch in rest position
"0" and/or unplug the electrical cable; close the
primary feed water valve and, if present, close even
the gas valve.
Perform every cleaning operation when the ma-
chine is cold and ever wear protective gloves.
Best device managing conditions:
-room temperature must be between +5°C and
45
