4. Prior to installation
4.1 Air Supply Openings
In case of ventilation based operation of the Paramount an adequately sized open-
ing for combustion air must be present in the place of installation. It should be
pointed out to the customer that this opening must never be closed or blocked and
that the connecting piece for combustion air on the upper side of the Paramount
must be kept free.
Concentric Flue Applications
The air supplied for the boiler space ventilation shall be such that the maximum
temperatures shall not exceed 25°C at floor level or 100 mm above, 32°C at mid
level (1.5 m above floor level) and 40°C at ceiling level or 100 mm below ceiling
level.
Refer to BS5440 2000 for boiler installations up 70 kW net and BS6644 2005 for
boilers above 70 kW net for further details.
The following tables give the total free area of the vents required for single boiler
installations in room sealed and open flue applications.
4.1.1 Clean combustion air!
Caution! Danger of damaging the device!
The Paramount must only be installed in rooms with clean combustion air. By no
means should pollen or similar particles be able to get into the equipment through
the suction holes!
4.2 Corrosion protection
Caution: Danger of damaging the device!
The combustion air must be free from corrosive elements - especially fluorine and
chlorine containing vapours which are found, for example, in solvents and clean-
ing agents, propellant gases etc.
When connecting heat generators to under-floor heating systems, employing plas-
tic pipe work which is 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.
4.3 Requirements for heating
circuit water
4.3.1 Further information on the heating water
- The water must not have any foreign matter, such as sweat beads, rust particles,
scale or sludge. During filling, flush the system until only clean water runs out.
When flushing the system,ensure that the water does not flow through the heat
exchanger in the boiler, that the thermostatic radiator valves are removed and
the valve inserts are set to the maximum flow rate.
- If additives are used it is important to follow the instructions of the manufactur-
er.
If, in a special case, it is necessary to use additives in a mixture (e.g. hardness
stabiliser, frost protection agent, sealing agent,etc.) it has to be observed that
the agents are compatible with each other and the pH-value is not altered. Pref-
erably, agents from the same manufacturer should be used.
- For buffer cylinders in conjunction with solar thermal systems or solid fuel boil-
ers, take the buffer capacity into consideration when determining the fill water
volume.
