APPLIANCE SPECIFICATIONS

Extraneous light / advanced ignition
During the pre-ventilation and/or pre-starting phase there shall
be no flame signal. Should the signal be present, for example for
advanced ignition due to bad tightness of the electrovalve, external
lighting, short-circuit in the photo-resistance or in the connecting
cable, a breakdown in the flame signal amplifier, and so on., when
the pre-ventilation and safety time has elapsed, the control-box
brings the burner to the emergency stop and cuts off fuel inflow
even during the safety time.
No flame
If there is no flame at the end of the safety time, the control-box
stops the burner immediately.
No flame during operation
If there is no flame during operation, the control-box cuts off fuel
and automatically repeats a new starting program: once the "t4"
time has elapsed, the starting program is over.
Every safety stop of less than 1 second switches off voltage to
terminals 3 - 8 - 11: and to terminal 10, it is possible to provide a
remote signal of emergency stop. Resetting of the control-box is
possible after approx. 50 seconds of emergency stop.

PREPARATIONS FOR START UP

Control that the nozzle applied is suitable for the boiler potentiality.
The table shows the delivery rates in kg/h of light oil with respect to
the nozzle size and the pump pressure (normally 12 bar). It should
be remembered that 1 kg of light oil is equivalent to approximately
10.200 kcal). Make sure that the return pipe in the tank has no
obstructions, e.g. gate valves, closed plugs etc. Any eventual
obstruction would cause a breakage in the sealing surface situated
on the pump shaft. Close the main switch and the boiler thermostats
in order to start up the motor and the ignition transformer. Upon
completion of the pre-ventilation time, the solenoid valve is activated.
the electrovalve will cut in and expose the photoresistant cell to a
source of light until the burner stops (shut down). When the pipelines
have been filled up (and when fuel has come out of the nozzle), stop
the burner and put the photoresistant cell back in its seat.
NOTE: Should it be necessary to purge air, this can be done by
loosening the special fitting which the pump is provided
with (see 8930/1). Do not illuminate the photoresistant cell
before the electric valve has cut in because, in this case,
the control box will go to "shut down".
