SAFETY DEVICES
To guarantee the correct functionality of
the appliance, this is equipped with the
following safety devices:
- Thermocouple fl ame control
it interrupts the fl ow of gas in case of
no pilot fl ame. The repetitive, not oc-
casional, intervention of this safety de-
vice, indicates an incorrect functioning
of the appliance for which the inter-
vention of qualifi ed 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.
However, the intervention of qualifi ed
staff is necessary for the removal of
the defect before re-ignition of the ap-
pliance.
