HOW TO FIND THE CAUSES OF IMPROPER WORKING OF BURNERS
USING TWO-STAGE LIGHT OIL AND HOW TO RECTIFY THEM
IRREGULARITIES
The apparatus goes into "lock-
out" with the flame (red light
on). Malfunctioning is due to the
flame control device.
The apparatus goes into "lock-
out", gas flows out, but there
is no flame (red light on).
Fault restricted to ignition
circuit.
T h e a p p a r a t u s g o e s i n t o
" l o c k - o u t " , g a s f l o w s
out, but there is no flame
(red light on)
POSSIBLE CAUSE
1) Disturbance to ionization current from the
ignition transformer.
2) Flame sensor (ionization probe) inef-
ficient.
3) Flame sensor (ionization probe) position
incorrect.
4) Ionization probe or relative earth cable.
5) Electrical connection cut-off by flame sen-
sor.
6) Inefficient draught or fumes passage
blocked.
7) Flame disk or combustion heads dirty or
worn.
8) Equipment fault.
9) No ionization.
1) Fault in ignition circuit
2) Ignition transformer cable discharges to
earth.
3) Ignition transformer cable disconnected.
4) Ignition transformer faulty.
5) The distance between electrode and earth
is incorrect.
6) Isolator dirty, so electrode
discharges to earth.
1) Air/gas ratio incorrect.
2) Gas pipe has not been properly bled of air
(in the case of first ignition).
3) The gas pressure is insufficient or exces-
sive.
4) Air flow between disk and head
too narrow.

SOLUTION
1) Invert the ignition transformer power supply
(230V side) and check using an analogue
micro-ammeter.
2) Replace flame sensor
3) Correct the position of the flame sensor, and
then check its efficiency by connecting the
analogue micro-ammeter.
4) Check visually and using the instrument.
5) Restore the connection.
6) Ensure that the boiler fumes passage and
chimney connection are free.
7) Visually check and replace, if necessary.
8) Replace.
9) If the "earth" of the equipment is not efficient,
the ionization current cannot be checked.
Check the efficiency of the "earth" at the
terminal concerned in the equipment and at
the "earth" connection of the electric system.
1) Check the ignition transformer power supply
(230V) and high voltage circuit (electrode to
earth or isolator broken under locking terminal).
2) Replace.
3) Connect.
4) Replace.
5) Position at the correct distance
6) Clean or change the isolator or electrode.
1 ) C o r r e c t t h e a i r / g a s
(there is probably too much air or very little
gas)
2) Bleed the gas pipe again, taking great care.
3) Check the maximum gas pressure value at
the time of ignition (use a water pressure
gauge, if possible).
4) Adjust the disk/head opening.
