♦ Manufacturing control
All boiler parts are checked and correctly set by the manufacturer prior to final assembly. Each boiler is
tested on water circuit tightness and the function of the regulating and safety components is set and tested as
well.
The boiler was manufactured in line with:
Standards: CSN EN 60 335-1, CSN EN 60 335-2-30, CSN 06 1008, CSN 07 7401, CSN 06 0810, CSN 07
0240, CSN 06 0310, CSN EN 60 730, CSN 06 0830, CSN EN 60 730-1, CSN 06 1010; Government
Regulations: No. 163/2002 Coll., 17/2003 Coll. and 18/2003 Coll.
5. Basic instructions for boiler installation
Electric boilers are designed for permanent connection to a fixed mains supply voltage. A disconnecting
device – main circuit breaker and a corresponding electric line protection – must be installed in the permanent
electric boiler mains.
Installation of electric boilers can be carried out only by a qualified expert company or authorized worker
with the required qualification level in the field of electrical equipment maintenance. In the process of
installation, all pieces of advice as well as warnings included in this Manual must be observed. It must be
performed in compliance with the valid standards and provisions! The connection of an electric heating is
subject to authorization issued by the local power distribution plant. An applicant must ask for a provisional
approval with the connection of a higher energy input and for a relevant direct heating dwelling unit tariff. In
the case of construction of a new or repair of an old central heating system, we suggest that the design is
elaborated by an expert. Performance of an expert installation by an authorized service organization is always
the precondition for warranty provision by the manufacturer! Connection to the electric network and the wiring
can be carried out only by an expert worker qualified in line with the Czech Decree No. 50/1978 Coll.
Installation location must be chosen for the electric boiler which will enable necessary access for the
operator or for the purposes of a service inspection. Minimum distances between the boiler and a solid obstacle
are shown in the Figure in the Chapter “Wall-mounting of a boiler”. Ask an expert worker of the company
which performs the installation for a demonstration of the system function and training for operation. Once the
boiler has been put into operation, a letter of guarantee must be certified by the authorized expert service
worker.
In the location of the electric boiler installation pressure water for filling the heating system and water
discharge point must be available. It is further necessary that the room has a sufficiently even wall (electric
boiler is wall-mounted).
♦ Boiler location
Electric boilers can be installed in the basic
environment AA5/AB5 according to the standards CSN
2000-3 and CSN 33-2000-5:51 (range of temperatures
between +5 and 40°C, humidity depending on the
temperature of maximum 85 %, no harmful chemical
influences). It can be installed in residential as well as
non-residential spaces with the exception of rooms with a
bathtub or shower, in bathrooms and wash rooms in
general in zones 1 and 2 according to CSN 33 2000-7-
701. It cannot be however installed in zone 3 in locations
where a water jet designed for cleaning can form. If the
