CHECKING THE SUPPLY PRESSURE

The gas supply pressure measured at
the pressure fitting 11 (fig.5), using a pres-
sure gauge and expressed in mbar.
ADJUSTING THE PILOT FLAME
(EUROSIT valve)
Adjust by acting on screw 13 (fig.5).
The pilot fl ame is correctly adjusted
when its length is approximately 2-3 cm
and the flame touches the upper part of
the thermocouple.

SAFETY DEVICES

To guarantee the correct functionality of
the appliance, this is equipped with the
following safety devices:
- Thermocouple flame control
it interrupts the flow of gas in case of
no pilot flame. The repetitive, not oc-
casional, intervention of this safety de-
vice, indicates an incorrect functioning
of the appliance for which the inter-
vention of qualified staff is necessary.
- Overtemperature thermostat
acts with the same methods of the
thermocouple in case the water tem-
perature exceeds 90°C; in this case,
the appliance cannot be re-ignited un-
til the hot water has been drained.
