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.
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
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
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.
Additives
The following products are currently approved by POTTERTON:
- „Protector CH3 or Alphi-11 Protector“ from Fernox (www.fernox.com)
- „Sentinel X100“ from Sentinel Performance Solutions (www.sentinel-solu-
tions.net)
The specifications of the manufacturer must be followed.
Caution: If non-approved products are used, the guarantee becomes void.
Antifreeze
Using antifreeze with Potterton gas condensing boilers with aluminium heat ex-
changers
The heat transfer medium (Tyfocor L) offered for solar thermal systems is also used
in heating systems (e.g. holiday houses) as an antifreeze. In the mixture supplied
in the canisters (50 % Tyfocor L, 50 % water). 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 -15 °C is usually sufficient.
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.
Maintenance instruction
The water hardness of the heating water has to be checked within the scope of the
recommended maintenance of the boiler and, possibly, the respective amount of
additive has to be added.
4.5 Practical notes for the
heating contractor
1. Taking account of the specific system volume (e.g. when using heating water
buffer cylinders), decide which requirements apply with regard to the overall
hardness of the fill and top-up water.
If partial softening to 6 °dH is insufficient an additive should be added.
If a boiler is replaced in an existing system, we recommend installing a dirt sep-
arator or filter in the system return, upstream of the boiler. Flush the system
thoroughly.
2. Depending on the materials used.

3. Document the filling process (if possible, use the POTTERTON system log. If an
additive is added, mark this on the boiler accordingly.). To prevent gas cushions
and gas bubbles, it is essential to fully vent the system at maximum operating
temperature.
4. After 8 to 12 weeks, check and record the pH value. Offer and conclude a main-
tenance contract.
5. Once a year, check the system is operating correctly with regard to pressure
maintenance, pH value and the volume of top-up water used.
4.6 Notes for installation
location
Caution! Danger of damage from water!
The following has to be observed for the installation of the Paramount:
In order to prevent damage due to water, particularly due to leakages in the DHW
storage tank, suitable precautionary measures should be taken regarding installa-
tion.
Installation room
The installation room must be dry, the room temperature must be between 0 and
40°C.
The installation location has to be selected, especially, with respect to ducting of
the exhaust gas flues. When installing the boiler, the specified wall clearances
have to be maintained.
Along with the general rules of the technology, the regulations of the country,
such as fire and construction regulations as well as heating room guidelines, are to
be observed. Sufficient space should exist in the front to carry out inspection and
maintenance work.
Caution! Danger of damaging the device!
Aggressive foreign substances in the combustion supply air can destroy or damage
the heat generator. Therefore the installation in rooms with high humidity or
heavy dust accumulation is not allowed.
Operation of Paramount boilers in rooms in which solvents, chorine containing
cleaning agents, paint, glues or similar substances are worked with or in which
such substances are stored is not permissible. This applies especially for rooms in
which ammonia and its compounds are heavily used, as well as nitrites and sul-
phides (animal breeding and recycling facilities, battery and galvanising rooms,
etc.).
Caution! Danger of damaging the device!
Furthermore it is to be observed that under aggressive atmospheres even the boil-
er external installation can be attacked. To this are also included especially alumi-
nium, brass and copper installations.
For damages occurring due to the installation in an unsuitable location or based
on improper combustion air supply, there is no warranty claim.
