Flue Probe And Safety Thermal Fuse - Biasi M300V.2025 SM User Manual And Installation Instructions

3.9 Flue probe and safety thermal
fuse
If the flue thermal cut-off fuse is
triggered, the boiler goes into
safety lockout. To restore nor-
mal boiler operation, please
contact an Authorized Service
Centre.
The flue probe and safety thermal fuse 18
indicated in Fig. 3.9 are a safety device. The
flue probe 18 intervenes when the flue tem-
perature exceeds 110°C placing the boiler
in safety block switching it off.
To reset normal boiler functioning, just press
the 14 (Fig. 3.7) key.
If flue probe 18 does not intervene and,
therefore does not send the boiler into secu-
rity lockout, flue thermal fuse 18 is triggered
as an additional safety device to protect the
flue outlet pipe.
To restore the normal operation of the boil-
er, contact the Authorized Service Centre.
