TWO-STAGE GAS BURNERS: TROUBLE-SHOOTING GUIDE
DETAILS OF PROBLEM
The apparatus goes into "lock-
out" with the flame (red light on).
Fault restricted to 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..
The apparatus goes into "lock-
out", gas flows out, but there is
no flame (red light on)
POSSIBLE CAUSE
1) Disturbance to ionization current from igni-
tion transformer..
2) Flame sensor (ionization probe) ineffi-
cient
.
3) Flame sensor (ionization probe) position
incorrect.
4) Ionization probe or relative earth cable.
5) Electrical connection cut-off by flame
sensor.
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 nar-
row.

SOLUTION
1) Invert the ignition transformer power supply
(230V side) and check using an analog micro-
ammeter.
2) Replace flame sensor
3) Correct the position of the flame sensor, and
then check its efficiency by inserting the analog
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 apparatus is not efficient,
do not check the ionization current. Check
the efficiency of the "earth" at the terminal
concerned of the apparatus 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) Pulire o sostituire l'isolatore e l'elettrodo.
1) Correct the air/gas ratio (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..
