9 .5 Checks

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 2 (Figure 9.2) are
complete.
If a fuse has blown replace it with one that has the same charac-
teristics after having identified the reason for failure.
Lock sequence
Start the boiler until the burner is ignited.
With the burner firing, interrupt the gas supply. The Main elec-
tronic 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.
9 .6 Removal of the electronic control p .c .b
Warning: isolate the boiler from the mains electrici-
ty supply before removing any covering or compo-
nent .
When replacing the Main electronic control/ignition p .c .b .
all parameters must be correctly checked / adjusted accord-
ingly with the values noted in table in the installation manual
see chapter COMMISSIONING section: Setting record (for
information on parameters see also section "9 .4 Setting the
boiler control function modes" on page 23) .
