Check Spark Generator and associated Harness
for continuity, visual condition and position (refer to
Frame 65). Are these functioning correctly?
Check Ignition Electrode and associated Harness
for continuity, visual condition and position (refer to
Frame 58). Are these functioning correctly?
Check Syphon and condensate drain pipework
for blockage and rectify if necessary. Boiler now
* Note: due to the wave form of the rectified voltage, the reading will vary depending on the type of meter used to measure
the value. In general terms a reading of greater than 150V indicates that the correct voltage is supplied to the gas
valve
79 ThERMAL FUsE LOCKOUT
Isolate the electrical supply to the boiler and system
Ensure that the electrical connection to the thermal
fuse is pushed fully home and that the 6 way connector
is properly connected to the primary PCB.
Disconnect the 6 way connector to the thermal fuse.
