IN ACCORDANCE WITH STANDARD EN 298
DISPLAY CARD .
flame control is supplied together
with the additional display card STK035.
This offers the opportunity to control the
functionality of the equipment in a more
effective and immediate way. This is
made possible by the four LEDs for
displaying the flame level, the LED for
controlling the safety systems and the
LED for remote unlocking. The latter also
remains slightly lit when the main switch is
in position 0 to indicate presence of
voltage (N.B. can only be used by
authorized personnel keeping under
control the burner to be turned on).
MOUNTING .
-Mounting position as desired
-Assembly of the fixed rear part,
through 4 preformed holes to be
removed by pressure.
- Dimensions 47 x 123 x 105 mm
- Prepared for pipe connection collars
- is not provided already wired,
otherwise perform the necessary
connection on the back by the 16
position connector.
RECCOMEND CABLES .
IONIZATION: Maximum length 10 meters with
recommended section 1 mm. Laying away from
sources of disturbance, avoid external electrical
influences.
IGNITION: as specified by the manufacturer of the
ignition transformer. Recommended conductor
diameter 1mm. Lay individually away from metal
parts.
WIRINGS .
Remove power from the system.
In three-phase systems, use the same phase on
the inputs. There must be no voltage present in the
output for the solenoid valve.
The enabling command of the that comes
from the safety sequence (all the main control
devices for safety purposes such as thermostats,
GASmin, GASmax, leakage control, prewash, etc.
...) must be voltage-free contacts.
The output voltage for the solenoid valve and the
ignition transformer (included if required) is the
same as the supply voltage.
The current max. for solenoid valve and ignition
transformer is 1A.
Alarm contacts max 1A 230Vac not protected by
internal fuse.
Make a good connection of the ground of to
the burner mass to ensure correct operation.

COMMISSIONING .
1. Open the gas valve.
2. Start the system.
3. Give power to the .
4. Press the power button (green power
LED lights up).
5. Switch on the enable terminal to start
the ignition cycle.
6. Waiting time at the start of about 5sec.
7. After this time the will carry out
the ignition cycle. The gas solenoid
valve will be commanded and the
discharge will be carried out at the
same time (yellow discharge LED will
light up). At the end of the discharge
the presence of the flame will be
checked.
8. In its presence, the equipment goes
into operation by turning on the green
detection LED and continuing to power
the solenoid Gas valve.
9. Otherwise will go into lockout (the
gas solenoid valve will be
disconnected, the alarm contact will
close and the red lock LED will light
up). To reset it and retry the boot it will
be necessary to switch it off and switch
it on again using the power button.
N.B. The terminl box should never be
used. This clamp has remote unlocking
functionality and must be used only by
authorized personnel, keeping the burner to be
re-ignited under strict control.
OPERATION CHECK .
1. Remove the detection plug during
operation.
2. will attempt to restart only once,
after which it will be shut down due to
an anomaly (the gas solenoid valve
will be disconnected, the alarm contact
will close and the red LED will light
up).
3. The burner flame must go out.
4. If a different operation should occur
check the wiring. This done if the
problem has not been resolved
disassemble the and send it to
the manufacturer for a complete
overhaul.
After replacing the safety device, check its
operation:
- Close the general gas valve and check
that the appliance, after a few attempts,
does not start.
If the safety device works correctly and
the wiring is in order but the equipment
attempts to start the burner, send it to the
manufacturer for a check.
OPERATING MODES GRAPHS .
Ta => waiting time before starting
(pre-purge Time)
Start without flame
Start with flame
Re-start after flame faliure.

RETIFICATION OF FAULTS .
? < TROUBLE>
! <CAUSE >
* <REMEDY>
? THE IGNITION SPARK DOES NOT
APPEAR.
! The distance between the electrode and
the burner body is too great.
* Set a distance of max. 2 mm.
! The igniter cable does not make contact
with the pipe.
* re-screw the pipe tightly.

* Screw it tightly on the ignition
transformer.
? THE GAS DOES NOT REACH IT
! The gas solenoid valve does not open
* Check the solenoid valve connection.
! There is still presence of air in the gas
hosepipe.
* Make many ignition attempts in order to
fill completely the gas hosepipe.
? THE GAS DOES NOT REACH IT
AND THE IGNITION SPARK DOES
NOT APPEAR, THE DOES NOT
START.
! Short circuit in the ignition or in the
solenoid valve outlet.
* Check the wiring
- in case of short circuit in outlets
eliminate it and change the inner fuse
(2,5 A). Or send the appliance to the
manufacturer.
? THERE IS THE FLAME BUT THE
DETECTION LED IS OFF.
! The detection electrode is in short
circuit because of dirt, soot or damp.
! The detection electrode is not in a
correct position as to the flame.
! The combustion air/gas ratio is
incorrect.
! The flame makes no contact with the
burner body because air and/or gas
pressure is too high.
! The burner or are not earthed
correctly.
! Short circuit or detection cable
interruption.
! Phase and neutral wire inverted.
* Eliminate the defect.
? THE APPLIANCE DOES NOT
PERFORM THE IGNITION CYCLE
AND GOES IMMEDIATELY IN
DETECTION.
! Anomaly on the detection (flame
simulation)
* Eliminate the cause of the flame
anomaly.
! Anomaly of the flame detection circuit.
* Send the appliance to the
manufacturer for its replacement.
? THE APPLIANCE DOES NOT
START EVEN IF ALL THE TROUBLES
HAVE BEEN ELIMINATED AND THE
MAIN SWITCH HAS BEEN PRESSED.
* Send the appliance to the
manufacturer for the functional
inspection.
CAUTION!!!
Danger of death due to shocks!
