3.9 Flue probe
The flue probe 19 and safety thermal fuse
20 indicated in Fig. 3.8 are a safety device.
The flue probe 19 intervenes when the flue
temperature exceeds 110°C placing the
boiler in safety block switching it off.
To reset normal boiler functioning, just press
the 14 (Fig. 3.6) key.
If flue probe 19 does not intervene and,
therefore does not send the boiler into se-
curity lockout, thermofusible 20 enters into
function as a further safety measure.
This component sends the boiler into se-
curity lockout when the flue temperature
reaches 167°C.
To restore the normal operation of the boil-
er, contact the Authorized Service Centre.
