Room thermostat (optional)(remove the existing bridge terminals 17-18)
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTA-
GE-FREECONTACTS. CONNECTING 230 V TO THE ROOM THER-
MOSTAT TERMINALS WILL PERMANENTLY DAMAGE THE ELEC-
TRONIC BOARD.
When connecting time controls or a timer, do not take the power supply
forthese devices from their breaking contacts Their power supply must
be bymeans of direct connection from the mains or with batteries, depen-
ding on thekind of device.a las pilas, según el tipo de dispositivo.

3.6 Connection to the
fl
ue
The unit must be connected to a
fl
ue designed and built in compliance with the cu-
rrentregulations. The pipe between the boiler and
fl
ue must be made from material
suitablefor the purpose, i.e. heat and corrosion resistant. Ensure the seal at the
joints. At the points of union it is recommended to check the tightness and thermally
insulate the entire duct between the boiler and chimney, in order to avoid the forma-
tion of condensation.
3.7 Condensate drain connection
The unit’s condensate drain must be connected to a suitable disposal system. Com-
plywith the speci
fi
c local and national regulations on discharging condensate water
into thewaste water disposal system. For boilers not using exclusively low-sulphur
gas oil (Scontent<50 ppm) make sure to provide for a suitable condensate neutra-
lisation device.
Connect the condensate drain pipe located at the back of the boiler (
fi
g.25) tothe
neutralisation device connected to the waste water system. The condensate dis-
charge pipes must be acidproof and installed sloping at least 3° towards the drain,
with-out any constrictions and obstructions.
IMPORTANT.
Fill the trap with water before starting the unit.
Verify. Periodically check the water in the trap.

The TEST mode is automatically disabled in any case after 15 minutes.
Burner adjustment
The burner is factory-set as given in table4. The burner can be set to a different
outputby acting on the pump pressure, nozzle, head adjustment, and air adjustment
as per thefollowing paragraphs. In any case, the new adjusted output must fall within
the boiler’snominal operating range. After making any adjustments, using a com-
bustion analysercheck that the CO2 content in the fumes is between 11% and 12%.

En la tabla 2 se indican los caudales de gasóleo (en kg/h) al variar la presión de la
bomba y de los inyectores.
N.B. -
The values given below are only approximate, since nozzle
fl
ow rates can
vary by± 5%. Also, with burners having a preheater, the fuel
fl
ow rate decreases by
about 10%.
