Safety measures
The distance between any fl ammable
material and the combustion gases
part of a separate ducting system must
be such that the surface temperature of
this material does not exceed 80˚C.
Combustion gases outlets must not be
located in:
• places with the danger of explosion (as
defi ned by ČSN 33 1220)
• building’s interior (attics, corridors, stair-
cases, etc.)
• places which can be closed, e.g. in gate-
way passages, etc.)
• underground structures (even when they
constitute no obstacle and are open),
such as tunnels, subways, etc.
The opening through the wall for dual du-
cting for air supply and fl ue removal shall
be made with adequate clearance (ca 120
to 130 mm) and sealed upon completion
of installation. Only incombustible material
may be used for sealing (with fl ammability
grade A according to ČSN 73 0823) as e.g.
plaster, gypsum etc. Penetrations through
fl ammable wall or ceiling must be made
in accordance with the fi rst paragraph of
this section.
The boiler is connected to power supply by
a three-core fl exible cord without a plug.
A fi xed socket through which the boiler is
connected to power mains must comply
with the provisions of ČSN 33 2000-4-46.
It must always have a protective (earth)
contact (peg), reliably connected by a PE
or PEN wire (yellow-and-green). The boiler
must be always connected to the protecti-
on wire (earth) through its power cord and
must be always installed in such a way
that the socket and plug are accessible.
Using adapters, extension cords etc., is
not permitted.
The boiler has two tubular fuses (T 80 mA/
250 V and 1.6 mA/250 V), situated on the
boiler’s control panel – see the schematic
diagrams on pages 35 and 36.
Important: The plug and the socket as
well as a room control unit, which requires
interfering with the boiler’s internal wiring,
must be always connected by a qualifi ed
electrician as defi ned by Public Notice No.
50/1978. Likewise servicing of the boiler’s
electrical system must be done by a per-
son with the above qualifi cation only. Before
carrying out any works on its electrical sys-
tem, the boiler must be disconnected from
power supply by pulling the power cord plug
from the power socket!
Only zero-potential output room control
units may be used with the boiler, i.e.
units which send no foreign voltage to
the boiler.
Minimum required current carrying capa-
city of the control unit’s output terminals is
24 VAC/0.1 A.
