Initial Fault Finding Checks
1. Check that gas, water and electrical supplies are available
at the boiler.
2. Electrical supply= 120V -60 Hz.
3. The preferred minimum gas pressure is 3.5"wc for
Natural gas and 10"wc for LPG.
4. Carry out electrical system checks, i.e. Ground
Continuity, Resistance to Ground, Short Circuit and Polarity
wilh"a suitable meter.
NOTE: These checks must be repeated after any servicing
or fault finding.
5. Ensure all external controls are calling for heat and check
all external and internal fuses. Before any servicing or
replacement of parts, ensure th� gas and electrical supplies
are isolated.
1. If a fault occurs on the boiler an error code may be shown
by the facia display.
!;20, fs28, !;40, !;5o, 1!1160, 1!1321 and 1!1431 indicate possible
faulty components.
l!l 53 shows possible obstruction in the flue duct.
I; 55 indicates that the pcb is not setting/calibrated.
1!71, 1!72, �7,
!;?a
e tl2 indicate possible wrong calibration. A
new calibration is needed.
1!192 shows possible flue recirculation in the flue duct.
I; 83 ... 87 shows possible error of communication with
thermost
at (Goto section P)
!;110 shows overheat of the primary.
1!1117 is displayed when the primary water pressure is more than
43
psi.
!;118 is displayed when the primary water pressure is less
than 7.25psi.
!;125 is displayed in either of two situations:-
0 If within a time between 15 .. 30 seconds of the burner lighting
the boiler temperature has not changed by 2 •F.
ii) If within 10 minutes of the burner lighting the boiler
temperature twice exceeds the selected temperature by 80 ° F. In
these instances poor primary circulation is indicated.
!;128 is displayed if there has been a flame failure during normal
burner operation.
I; 133 , I; 134 and I; 135 indicate that the gas supply has been
interrupted, ignition has failed or the flame has not been
detected.
2. By pressing the 'Reset' button for between 1-3 seconds when

m
134,I; 135 ,'3 09, '3 1s,'3128 andl3384
are displayed it is possible to relight the boiler.
3. If this does not have any effect, or error codes are displayed
regularly further investigation is required.
