CONDUIT ALARM
PELLET
Indicates overheating of the pellet
feed conduit.
In the case of pellet loading conduit overheating the boiler initially
intervenes by starting the “
CONDUIT CLEANING
” cycle. If this is
not suffi
cient, after a period of about 10 minutes the boiler will block,
showing “
PELLET CONDUIT ALARM
”” on the display.
During this alarm, do not:
Open the upper door
Open the lower door
Open the pellet tank lid
At this point re-attempt the ignition phase: if the alarm remains blocked
on the display not allowing any operation, it means that the conduit
is not cool enough. Wait for the complete cooling of the conduit and
repeat the ignition phase.
