USEFUL ADVICE
If flue probe 14 does not intervene and,
therefore does not send the boiler into secu-
rity lockout, flue thermal fuse 14 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.
