Care
and maintenance
Clean
the
outer
casing
of
your
boiler
with
a damp
cloth
and
a little
soap. Do
not
use abrasive
or solvent
cleaning
agents
that
may
damage
the
case
or the
plastic
fittings.
The
appliance
should
be serviced
at least
once
per
year.
To
ensure
regular
servicing,
it is
strongly
recommended
that
arrangements
are made with
your
service
agent
or
Vaillant
Ltd.

Frost
protection
Your
boiler
is
equipped
with
a frost
protection
function:
lf
the heating
water
temperature
drops
below
5
oC
when
the
main
switch
is
ON,
then the
boiler
goes
into
operati-
on
and heats
the
boiler
circuit
to approx.30
oC.
It
cannot
be
guaranteed
that water
will
circulate
throughout
the
entire heating
system.
lf
the
boiler is
not
operated
for
several
hours
during
very
cold weather
there
is
therefore
the
possibility
of
the
system
freezing.
Please
ensure
that
if
you
are
absent
during
a
period
of frost
the
central
heating
remains
in
operation
and all rooms
are kept
above
freezing
point.
It
must
be remembered,
however,
that
the boiler
will
be
automatically
switched
off
by the
built in
monitoring
devices
if
certain
faults
occur;
e.g. interruption
in
the
gas
or
electricity
supply
or faults
in
the flue
gas
system.
To
overcome
this
possibility
you
can
drain
both the
central
heating
system
and
boiler.
Frost
protection
and
monitoring
devices
can
only
function
when
the main
switch
of the
unit
is
set to
the
,,1"
position
and the
boiler
is
connected
to
the electrical
supply.
