baltur BPM 90 - Instructions for Determining the Cause Leading to Irregularities in the Operation and Their Elimination

INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO IRREGULARITIES IN THE OPE-
RATION AND THEIR ELIMINATION
IRREGULARITY
Appliance locks out due to no ame (red light
lit).The fault is in the ame control device.
POSSIBLE CAUSE
- Disturbance to ionization current from
the ignition transformer.
- Flame sensor (ionization probe) inef-
cient.
- Flame sensor (ionisation probe) position
incorrect.
- Ionization probe or relative ground
cable.
- Electrical connection cut-off by ame
sensor.
- Inefcient draught or fumes passage
blocked.
- Flame disk or combustion heads dirty or
worn.
- Equipment fault.
- No ionization.
REMEDY
- Invert the ignition transformer power
supply (230V side) and check using an
analogue micro-ammeter.
- Replace the ame sensor.
- Correct the position of the ame sensor,
and then check its efciency by con-
necting the analogue micro-ammeter.
- Check visually and using the instru-
ment.
- Restore the connection.
- Ensure that the boiler fumes passage
and chimney connection are free.
- Visually check and replace, if neces-
sary.
- Replace it.
- If the “earth” of the equipment is not
efcient, do not check the ionization
current.Check the efciency of the
“earth” at the terminal concerned in the
equipment and at the “earth” connection
of the electric system.
The burner goes into “lock-out”, gas ows,
but there is no ame (red light on).Fault in
ignition circuit.
- Fault in ignition circuit
- Ignition transformer cable discharges to
earth.
- Ignition cable disconnected.
- Ignition transformer is faulty.
- The distance between electrode and
ground is incorrect.
- Insulator dirty, so electrode discharges
to ground.
- Check the ignition transformer power
supply (230V) and high voltage circuit
(electrode to earth or isolator broken
under locking terminal).
- Replace it.
- Connect it.
- Replace it.
- Position it at the correct distance.
- Clean or change the insulator or electro-
de.
The burner goes into “lock-out”, gas ows,
but there is no ame (red light on).
- Air/gas ratio incorrect.
- Gas pipe has not been properly bled of
air (in the case of rst ignition).
- The gas pressure is insufcient or
excessive.
- Air ow between disk and head too
narrow.
- Correct the air/gas ratio (there is pro-
bably too much air or very little gas)
- Bleed the gas pipe again, with due
caution.
- Check the maximum gas pressure value
at the time of ignition (use a water pres-
sure gauge, if possible).
- Adjust the disk/head opening.
