DANGER:
Health risks due to mixing the drinking water and water from heating
installation!
Comply with the existing regulations and norms related to avoiding mixing
drinking water and water from heating installation.
Comply with the norm EN1717.
DANGER:
Risk of fire due to flammable materials or liquids!
Do not store flammable materials or liquids in the vicinity of the boiler.
Inform the end-user about the regulations in effect relating to minimum
clearance from easily flammable materials (more information in the table 2).
NOTE:
Damage on installations caused by poor quality of water! Depending on
the water characteristics, there might be damages of corrosion or lime scale on the
heating installations.
Comply with the requests relating to filling water as per VDI2035, i.e. as per
the design documentation and catalogue.
NOTE:
Material damage caused by temperature strain. If the boiler is filled in a
warm state, thermal stress may lead to cracks. The boiler will start to leak.
Fill the boiler only in cold state (the temperature of the flow may be
maximum 40°C)
Check the pre-pressure of the expansion vessel.
-
Open the filling and drainage tap.
-
Slowly fill the boiler.
-
At the same time monitor the pressure on the sphygmomanometer. When the working
pressure has been reached, close the filling and drainage tap.
-
Purge the boiler through air vent.
-
Purge the installation through a valve on the radiator.
-
Once the working pressure has been reduced by purging of air, the water in the system
must be refilled.
-
Test the tightness in accordance with the regulations in effect.
-
Check whether all safety elements work properly.
-
If the tightness has been tested and no leakage has been observed, regulate the right
working pressure.
