Screw on the new nozzle (56), and position the primary air adjusting ring nut (55 - Fig. C) according to the
indications of Table 1, using a gauge or equivalent instrument to set the distance “L”, and tighten the screw
provided to fasten the nozzle.
Turn the main switch (1) to position 1, so as to connect a single heating element (50% of the boiler’s electric
power for single-phase heating element with 2 elements and 1/3 of power for heating elements with 3 ele-
ments with three-phase connection), and ignite the burner as in the procedure described above. When the
water contained in the boiler reaches the preset temperature, the gas flow regulator will automatically decre-
ase the flow to the value corresponding to the reduced rated heat flow.
At this point, turn the flow regulation screw (58) so as to have a steady flame licking the sensitive thermocou-
ple element (52), and turn the screw (57) to obtain the maximum desired pressure value in the boiler.
After having verified the proper operation, replace the settings tag on the appliance with the one for the new
type of gas that is provided with the standard kit containing the newly installed gas nozzle.
Safety devices on appliance (manually reset).
The appliance is provided with two safety devices that shut off the gas flow if the flame accidentally goes out.
1 - Termocouple (52)
: The thermocouple operates on the valve (51), whose probe (52) must be licked by
the flame from the burner (50). If the probe is not enveloped by the flame, the gas flow will be automa-
tically shut off.
2 - Thermostat (59)
: The thermostat, placed in contact with the boiler, operates on the valve (51); when the
thermostat sensor on the boiler reads 140˚C, the gas flow will be automatically shut off.
The burner can be re-ignited with the procedure described above only after the boiler body has cooled to
110˚C. Following the activation of one of the two safety devices, try re-igniting the burner with the procedure
already described.

The symbol with the crossed-out dustbin on the appliance or its packaging indicates that at
the end of the product’s life cycle, it must be collected separately from other waste.
Suitable separate collection of the equipment for subsequent recycling, treatment and di-
sposal contributes to preventing possible negative consequences for the environment and
health, and favours the recycling of materials that the unit is made of.
In accordance with European Directive 2002/96/EC, abusive disposal of the product by the user will result in
