2.3. HYDRAULIC INSTALLATION
RULES
2.3.1. Radiator and DHW Installations
Radiator and ground heating installation should be
constructed in accordance with legistation in force,
technical specifications and heat loss calculation. Radiator
type and amount and ground heating installation pipe
amount should comply with the heat loss calculation.
• Radiator installation should be designed as resisting to
at least 6 bars.
• If the city grid pressure is higher than 6,5 bars, pressure
reducer must be installed.
• It is recommended to construct the radiator installation
as double line and without using bends and joints as
much as possible.
• Strainer filter must be installed in radiator return and
tap water (city grid) input line.
• For example; as the radiator cycle’s 7 litres expansion
(25 kW) tank (1.0 bar) can support maximum (75
°C in radiator system) 75 litre and (55°C in ground
heating system) 100 litre installation water expansion,
additional expansion tank should be used for larger
installation volumes. 150 litre installation water
expansion, additional expansion tank should be used
for larger installation volumes.
• If the room thermostat and thermostatic radiator valve
shall be used together; thermostatic valve should
not be installed in radiators in the place where room
thermostat is available!
• Cross connection must be made for efficient
functioning in radiators longer than 1,5 m.
• Covers should be used for radiator and hot tap water
wall passages and fixed with wall clamps for preventing
slopes in expansions due to heating.
• Combi boiler can function at minimum 0,5 bar tap
water pressure and that corresponds to a very low
flow rate and therefore, it is quite probable that the
requested tap water temperature can not be provided.
For this reason, tap water line should be installed at
shortest distance with pipe having at least ½” internal
diameter and by using bends as low as possible. At
least 1 bar pressurized grid input water should be
supplied for acquiring the comfort requested in the hot
tap water. Hydrophore should be used if required.
• Prior to filling the radiator installation, it must be
flushed and all wastes must be cleaned!
Warning:
In order to prevent invalidity of
device warranty prior to making combi boiler
connections, clean residues likely to exist in
main heat exchangers (pipes, heater assembly, etc.) via
dissolvent or equal substances, otherwise they will
negatively affect functioning of the combi boiler. In order
to prevent lime scales in the heating circuit and therefore
faulty operation of installation, follow rules envisaged by
standards regarding domestic tap water and radiator
installations.
Warning:
It is recommended to install a Anti-
Lime Kit for preventing occurrence of lime
scales at places where water hardness is higher
than 25 French degree in order to protect service life and
efficiency of the hot tap water heat exchanger.
2.3.2. Filling/Emptying Radiator Installation
To fill the radiator circuit of the combi boiler, make sure
that the pressure in the heating line reaches 1-1.5 bar by
turning the Fill Valve clockwise indicated by symbol 2 in
Figure 7.
After installation close the Filling Tap by rotating clockwise
and discharge air of radiators via air discharge valves.
Combi boiler safety valve discharge should be connected
to a discharge funnel. Otherwise, safety valve shall be
activated and manufacturer shall not be responsible due
to water discharge to the place of device.
Discharging the Condensation Water
For discharging the condensation water produced by the
device, it should be connected to waste water grid via
at least Ø 19 mm pipes resistant to acidic condensation
waters. Connection of the device with waste water
