5.1 Regulations governing installation
Caution
Installation of the appliance must be done by a qualified engineer
in accordance with prevailing local and national regulations.
5.2 Installation requirements
5.2.1 Corrosion protection
Caution
The combustion air must be free from corrosive elements - espe
cially vapours containing fluorine and chlorine which are found, for
example, in solvents and cleaning agents, propellant gases etc.
When connecting heat generators to under-floor heating systems employ
ing plastic pipes which are not impervious to oxygen in accordance to DIN
4726, heat exchangers must be used for separation purposes.
Note
Prevention of damage in hot water heating systems caused by
corrosion on the water side or scaling.
5.2.2 Supply air openings
Caution
Keep the inflow area clear.
Never block or close off ventilation apertures. The inflow area for
combustion air must be kept clear.
Warning
Risk of damage.
The gas condensing boiler may only be installed in rooms with
clean combustion air. Foreign matter such as pollen must never
filter through the inlet apertures to reach the inside of the appli
ance. The boiler must not be started up if there is heavy dust de
velopment e.g. during construction work. There could be damage
to the boiler.
Where the Paramount four is operated based on room ventilation, there
must be a sufficiently large opening for combustion air available in the in
stallation room. The operator must be informed that this opening must
never be closed or blocked and that the connecting piece for combustion
air on the upper side of the Paramount four must be kept free at all times.
5.2.3 Heating water requirements
Caution
Observe the heating water quality requirements!
Requirements regarding heating water quality have increased in
recent times as system conditions have changed:
lower heat demand
use of gas condensing boilers in cascade in larger projects
increased use of buffer storage tanks in combination with solar
thermal systems and solid fuel boilers.
The focus is always on designing systems that guarantee trouble-
free service over a long period.
Generally speaking, the quality of drinking water is adequate, but it must
be checked whether the drinking water actually filled into the system is
suitable when its hardness is taken into consideration (see
water hardness

). Where that is not the case, different steps can be taken:
