Before final installation of the boiler, the
heating system distribution pipes must be
flushed several times by pressurised wa-
ter. In old, already used systems, this is
done in the opposite direction to the heat-
ing water flow.
Boiler’s location
If there are special requirement on ma-
nipulation with the boiler (e.g. in order to
prevent its covers from getting damaged,
to reduce its width, etc.), the boiler, deliv-
ered assembled, can be partially disas-
sembled.
Enough manipulation space should be
left around the boiler and the connected
devices, to allow adequate access and
works using tools to be performed.
Leaving adequate free space around the
boiler will also satisfy the requirements for
the so-called safe (fire) distance.
Prevention against freezing
Unless the boiler is protected against
freezing by implementing technical and
organisational measures around the boil-
er (controls, operator), it will necessary to
shut it down possibly together with some
other equipment in the boiler’s vicinity (the
boiler room), such as for instance a water
treatment plant, water top-up equipment,
etc., or the entire heating system will have
to be shut down, i.e. the water drained,
and the supply of water, gas and electric-
ity to the boiler shut off.
Connecting the boiler to power
supply
The boiler is designed to be hardwired to
power supply. The electric boiler’s hard-
wired connection must have a disconnec-
tion device built in – a main switch, with
the distance between open contacts at
least 3 mm in all poles, with all regulations
for switching the boiler being abided by.
The boiler is connected to power supply
by means of a terminal box which has
terminals for a three-wire connection. The
boiler must be wired to power supply in
accordance with STN 33 2000-4-46
[Slovak
Technical Standard Specifications]
. Its protective contact
(peg) must be always connected to the PE
or PEN wire (green and yellow).
It is prohibited to use any type of adapters,
extension cables, etc. The boiler is pro-
tected against overloading and short cir-
cuit by a T 4A / 250 V fuse, located on the
control panel. The fuse must be replaced
by authorised service only.
Boilers controlled by a room thermostat
must use only thermostats which have a
potential-free output, i.e. those which do
not feed any alien voltage into the boiler. It
is recommended that a suitable room ther-
mostat is selected by authorised service.
The boiler must be placed on a building
base, i.e. floor (or on a pedestal). The
floor must have at least normal load-bear-
ing capacity and must not be slippery.
The space around the boiler may be only
cleaned in a dry way (e.g. by vacuuming).
The boiler must be positioned on an in-
flammable mat. If the floor is constructed
of a flammable material, it must be put on
an inflammable, thermally insulating mat,
exceeding the boiler’s footprint by at least
100 mm.
When transporting the boiler with the cov-
ers on, doors must be at least 100 cm
wide.
Important:
Unauthorised persons must
not interfere with the boiler’s setting (par-
ticularly those with an impact on the com-
bustion process), to prevent an increased
generation of harmful substances in the
combustion fumes, operation noise, re-
duced heat utilisation or heat generation,
etc.).

The boiler must not be installed in an environment in which the burner tubes can get
clogged up by dirt or biological agents (small living creatures).
The boiler has an outlet for connecting
a room thermostat, located on a printed
circuit board. As an option, the boiler can
be supplied with the so called switching
kit, used to interconnect with boiler an
equithermal control unit. For a specific
control unit type must be ordered a spe-
cific kit. These switching kits support as
standard Siemens Albatros control units
RVA43.222, RVA63.242 and RVA63.280,
Important: If a different control unit is used,
it must not restrict of disable the boiler’s
safety functions.
Siemens control units
Albatros RVA43.222 is an equithermal
control unit designed for standalone boil-
ers or cascaded boilers.
It is suitable for serial connection to the
source of heat with:
• one or two-stage burner
• hot water supply pump or bypass valve
• boiler pump, supply pump, or heating
circuit pump
Heating circuit is controlled equithermally,
hot utility water heating is controlled by
temperature in the tank and a time pro-
gramme.
By combining more RVA43.222 control
units, you can create a stepped up cas-
cades of multiple (maximum 16) sources
of heat.
Albatros RVA63.242 is an equithermal
control unit designed for serial connection
to the source of heat with:
• one or two-stage burner, 1BMU
• hot water supply pump or hot water he-
ating bypass valve
• three-point blender drive with circulation
pump
• various multi-function outlet applicati-
