temperature is not reached, the output will be
increased).
Insulate the connection to the chimney!

In “Heating” status: if the difference between flue gas
temperature and boiler temperature falls below this
specified value, when the safety time has elapsed, the
controls go to “Fault” status
“Safety time elapsed
too low”.
In “Ignition” status: if the difference with the “Ignition
time max” does not exceed the value, the boiler goes
to “Fault”
“Ignition attempt failed”

After heating, the flue gas temperature must have
risen by this value compared to the value before the
heating phase, to reach the status “Heating up”.

The boiler changes from “Ignition” status to “Heating”
status within the “Ignition time max” if the flue gas
temperature has reached the required value (“Min.

goes to the fault
“Ignition attempt failed!”.
