ECOCONDENS SILVER PLUS
ISU-646:2016/GR-H str.11
•
Install a water filter on a water return from central heating system (in front of the connection with the pump). The filter is
not included in standard boiler equipment.
•
The central heating system should be thoroughly rinsed out before the boiler is connected.
•
In the central heating system it is permitted to use as a heat carrier any antifreeze fluids which can be used in central heating
systems.
•
The cut-off valves needs to be installed between the boiler and central heating system so that the boiler could be dismounted
without draining the system.
•
Do not install any thermostatic valves on radiators in the room where the thermostat is installed. The temperature controller takes
the control over the function of temperature and it cooperates with the boiler.
•
On at least one of radiators of the central heating system there shouldn`t be installed a thermostatic valve.
•
It is recommended to lead out a water from a safety valve 0,3 MPa (3 bar) (item 25) to a floor drain by a tube or hose otherwise
during the safety valve activation there is a risk of flooding a room what is excluded of producer’s liability.
Selection of expansion vessel
Boilers ECOCONDENS SILVER PLUS are adjusted to be connected to a central heating system with the maximum capacity of 105
liters. The assembly to installation with larger capacity is acceptable only after applying an additional expansion vessel. A proper
expansion vessel should be selected by the designer of central heating system.
Installation of expansion vessel should be made by an installation contractor in accordance with applicable regulations.
NOTICE! : Before installing the boiler thoroughly flush the central heating system to free it from any solid impurities.
It is recommended that after first start up of the boiler and heating up of the installation drain the water from the system to remove
residues of pastes metallurgical and precautionary measures of heaters. These activities would benefit for the operation of the device,
its parameters and components life.
After boiler installation:
•
Fill the heating system with water by filling valve
item 22 Fig 2.2.1.1. for combi boiler. For system boiler install filling valve from
the installation. Pressure in cold installation should amount 1,0 to 1,5 bar (indicated by manometer).
•
Vent the installation of central heating and boiler;
•
Check the tightness of boiler connections in central heating system.

3.5.2
System cleaning and water treatment for the C.H. filling.
Every component of C.H. system is threatened by limestone deposits, corrosion and other dangerous processes. Boiler is the most
expensive part of C.H. system and it is necessary to protect its components like heat exchanger and other parts against harmful
processes. Correct C.H. circuit preparation for using relies on making two operations: cleaning the CH system and treating the water
that fills the system.
System cleaning
In new installation it is possible to find some remains of industrial process jak soldering and welding remains, flux, oil and grease
residue among others. Older installations usually have products of corrosion in them. It necessary to clean up the systems with a water
to remove the remains before boiler is mounted. Afterwards, system should be cleaned with appropriate chemicals. For example
Cleaner F3 from Fernox in new installations. For old and contaminated systems it is best to use Cleaner F5). Afer that it is necessary to
rinse the installation with water.
Water treatment to fill the system
For filling the system, it is recommended to use water with parameters: pH 6,5- 8,5, hardness < 10 °n (~ 18°F). Do not use
demineralised or destilled water. To ensure protection against rocks despositing, corrosion, it is recommended to use a special
inhibitor, for example Fernox Protector F1. Heat transfer fluid HP-5 or antifreeze liquid can also be used, for example Fernox Alphi 11.
If the water hardness is very high, the HP-5 effectively reduces the risk of heat exchanger calcification.
