6.5 Checks
n
Check that the fuses are complete
If the Main electronic control/ignition p.c.b. does not
supply any device (pump, fan, etc.) check that the
fuses 10 (Fig. 6.2) are complete.
If a fuse has blown replace it with one that has the same
characteristics after having identified the reason for fail-
ure.
n
Lock sequence
Start the boiler until the burner is ignited.
With the burner firing, interrupt the gas supply. The
Main electronic control/ignition p.c.b. must carry out
four complete ignition cycles and then, after about 4
minutes, goes to lock---out state.
Switch off and on the electricity supply to the boiler, by
means of the fused spur isolation switch, the device
must not unlock and the burner must not turn on
6.6 Removal of the electronic control p.c.b
Warning: isolate the boiler from the mains
electricity supply before removing any
covering or component.
When replacing the
Main electronic control/ignition
