Wall-mounting of the boiler
Electric boiler is mounted on the wall by means of a
fixing strip (1) supplied with the boiler according to the
Figure in the Chapter “Wall-mounting of the boiler”. If the
boiler is mounted on a wall with a lower carrying capacity, it
is recommended to consult the installation with a civil
engineering technician. Free space of at least 200 mm below
and 750 mm above the lower and upper edges of the
jacketing shall be left for the purposes of inspecting the
boiler or replacing the heating bodies (see Figure depicting
the boiler wall-mounting and installation).
Connecting the boiler to the hot-water heating system
Electric boiler must be connected to the distribution network in a manner preventing its aeration. Connection to
the heating system must be tackled in a project design calculating hydraulic ratios of the whole system because the
installation involves a hot-water flow-through boiler fitted with an integrated pump. It needs be noted that
minimum flow through the boiler must be constantly assured for the designated boiler output at maximum thermal
gradient of the heating system amounting to 20°C. Any reduction of this flow (due to integrated high hydraulic
friction elements) results in insufficient circulation and drop in life-time of some boiler parts. To utilize the
maximum output of the heat exchangers, ensure correct functioning and high durability, the minimum heating
system overpressure must amount to 0.8 bar.
Proper rinsing of the heating system resulting in the removal of all impurities must be performed prior to testing
and launching the operation of the whole system in line with CSN 06 0310 within the framework of the installation.
A suitable filter must be unconditionally fitted in the recuperative water inlet from the heating system into the
boiler to prevent impurities from entering the boiler system.
The heating system must be installed in accordance with CSN 06 0830 -- Safety equipment for central heating
and domestic hot water heating and CSN 06 0310 Central heating designing and assembly.
Shall the boiler be connected to a sealed heating system, such system must have a pressure expansion vessel of
sufficient capacity (higher performance series boilers are not equipped with their own expansion vessel).
!!! We recommend:
fill the system with soft water in line with CSN 07 7401;
fit the boiler outlet with a bleeding device;
mount a filter or a sludge device into the pump suction section;
overflow valve should be installed in heating systems with thermostatic valves
mount a heating system charge and discharge cock and a sludge cock at the lowest point of the system in
the very proximity of the electric boiler
separate all electric boiler types on inlet and outlet by stop valves, too (see standards CSN 06 8030), not to
be forced to discharge the whole system in case of inspection or repair of the boiler or during filter
replacement
remove control levers from stop valves and secure them against manipulation.
Boiler connection to electric network
Wiring can be installed only by an authorized person in the sense of the Decree No. 50/1978 Coll. on
professional qualification in electrical engineering. Certification of the boiler installation and putting into operation
