When
a
hot
water
tap
(turboMAX
plus
only) or
the
central
heating
system requires
heat,
the
boiler automatically
ignites
and
starts to
operate. tf
the automatic
ignition
is
not
successful
within 1O
seconds,
then the
boiler
does
not
go
into
operation
and switches
to
,,Lock
out".
This is
indicated
visually
by the red
indicator
tight
(1)
and
the
displaying
of fault
code
,,F.28"
or
,,F.29"

The
boiler also
switches
to
,,Fault"
when
there
is not
enough water
in
the system. This
fault is indicated
by
fault
code
,,F
22". The
boiler
can only
be
placed
back in
operation
after

system has
been
properly
refilled
with
water.
ln
the unlikely
event
of any other fault
developing, which
