3.7.3
Fuel pre-heating function (only for suitable
applications)
The burner is equipped with the fuel pre-heating function, in the
presence of a start request from the heat request thermostat of
the boiler, the burner awaits the closure of the start-up thermostat
(or pre-heating, K) positioned on the nozzle holder.
If the start-up thermostat (or the pre-heating one) does not close
within 600 seconds, the burner goes into lockout mode.
If the flame goes out during operation, the burner carries out re-
cycling if the contact of the start up thermostat (or the pre-heating
one, K) is closed.
If the flame goes out during operation and the contact of the start
up thermostat (or the pre-heating one, K) is open, the purging
stops and the burner waiting for the closure of the contact of the
start up thermostat (or the pre-heating one, K) to restart with the
pre-purging time.
3.7.4
Shut-down test
If the reset push-button is pressed during running operations for
more than 5 seconds and less of 10 seconds the burner will per-
form a shutdown, the oil valve is closed, the flame stop and start-
up sequence restarts.
If the switch off test is enabled, the number of repetitions of the
start up sequence (see paragraph "Recycle and limit of repeti-
tions" on page 11) and the number of possible resets (see par-
agraph "Protection reset" on page 11), are reset.

Intermittent operation
After 24 hours of continuous operation, the control box starts the
automatic switch-off sequence, followed by a restart, in order to
check for a possible fault with the flame sensor. This automatic
switch-off can be fixed at 1 hour, (see paragraph "The deactiva-
tion of the automatic pre-heating is not lost if the switching
off test is activated or if the heat request thermostat opens."
Tab. E
on page 14).
The modification of the parameter setting for intermittent opera-
tion takes effect if:
during the heat request, the switching off test function is ena-
bled;
there is a flame loss;
the heat request switches off and then later restarts;
the control box switches off and restarts;
the automatic restarting of the intermittent function occurs
(1hour/24hours).
