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.

4.4 Treating and preparing the
heating water 4.4.1 Determining the system volume
The total water volume in the heating system is composed of the system volume
(= fill water volume) plus the top-up water volume. In the POTTERTON boiler-spe-
cific diagrams, only the system volume is given to make them easier to use. Over
the entire service life of the boiler, a maximum top-up volume of twice the system
volume is assumed.
4.4.2 Additives
The following products are currently approved by BRÖTJE:
- „Full heating protection“ from Fernox (www.fernox.com)
- „Sentinel X100“ from Guanako (www.sentinel-solutions.net)

- „Vollschutz Genosafe A“ from Grünbeck
- "Care Sentinel X100" from Conel (www.conel-gmbh.de)
Complete softening
As a general rule, fully desalinated water can always be used, although a pH value
stabiliser is also required. The following products for producing fully desalinated
water have been tested and approved:
- „Complete softening (VE) GENODEST Vario GDE 2000" from Grünbeck
(www.gruenbeck.de)

Partial softening
The following products are currently approved by BRÖTJE:
- Sodium ion exchanger "Fillsoft" from Reflex (www.reflex.de)
- "Heifisoft" from Judo (www.judo-online.de)
- "Heating water softening 3200“ from Syr (www.syr.de)
- "AQA therm" and "HBA 100" from BWT Wassertechnik (www.bwt.de)
- "SoluTECH" from Firma Cillit (www.gc-gruppe.de)
It must be ensured with an automatic blending device that the min. hardness
does not go under 6°dH .
The specifications of the manufacturer must be followed.
Further products are currently undergoing testing. Please ask BRÖTJE for more in-
formation.
Caution! If non-approved products are used, the guarantee becomes void.
4.4.3 Antifreeze
Using antifreeze with Potterton gas condensing boilers with aluminium heat ex-
changers
The heat transfer medium (Lasacor®LS 1) offered for solar thermal systems is also
used in heating systems (e.g. holiday houses) as an antifreeze. In the mixture sup-
plied in the canisters (42 % Lasacor®LS 1, 58 % water) the freezing point ("crystal
formation point") is -28 °C. Due to the thermal capacity, which is lower than that
of pure water, and the higher viscosity, boiling noises may occur in some systems.
For most heating systems, frost protection down to -28 °C is not required; -15 °C is
usually sufficient. To set this operating point, the heat transfer medium should be
diluted with water in a ratio of 2:1. This mixing ratio has been test by Potterton in
relation to its practical suitability for use with gas condensing boilers.
Note: The heat transfer medium Lasacor®LS 1 up to a mixing ratio of 2,5:1 is ap-
proved as an antifreeze down to -15 °C for use with Potterton gas condensing boil-
ers.
Caution! Keep the installation room free of frost.
If antifreeze is used, pipework, radiators and gas condensing boilers are protected
against frost damage. For the gas condensing boiler to be ready for operation at
any time, suitable measures must also be taken to keep the installation room free
of frost. If applicable, please also note special measures for any installed DHW
heaters.
The table shows the relevant amounts of heat transfer medium and water, that
need to be mixed together for varying volumes of water. If other frost protection
temperatures are required in exceptional cases, individual calculations can be
made.
