1. Regarding this Manual
Read this instruction booklet thoroughly before operating the boi-
ler!
1.1 Content of this manual
This manual contains the instructions for the installation of the PA-
RAMOUNT two for standard applications with 1 heating circuit and/
or 1 DHW circuit (WWF tank sensor required for DHW).
Further applications can be made available (for multiple boilers
and multiple zones) by installing extension modules (clip-ins).
Keep all documents at the installation location of the boiler!
1.2 Used symbols

2. Safety
Danger! Absolutely observe the following safety instructions!
Otherwise, you may endanger yourself and others.
2.1 General safety precautions
Installation of System:
Important: The boiler must be commissioned following completion
of installation. Operation of an un-commissioned appliance may
cause injury to personnel and damage to the boiler unit which
would invalidate the warranty.
Commissioningmust only be carried out bypersonnelapproved and
competent to do so. This facility is available from Potterton Com-
mercial Service Office.
Important: the boiler unit is supplied in accordance with Potterton
Commercial quality assurance plan registered to meet the require-
ments of BSN ISO 9002. A condition of the supply of the appliance
for compliance with this is the return of the appliance commissio-
ning report.
Electrical Installation:
The electrical installation work must be carried out by a qualified
electrician.
Gas Installation:
Boiler installation as well as commissioning, servicing and mainte-
nance must be carried out by an approved gas installer. For use
with natural gas (G20) nominal supply pressure 20 mbar (LPG opti-
on available).
2.2 Use The POTTERTON PARAMOUNT two wall hung condensing boiler is
available in six sizes with outputs from 30 kW to 115 kW.
They are CE marked for use on Natural Gas (LPG) on open vented
systems (min 1 bar) and are suitable for use on sealed systems with
a maximum operating pressure of 3 bar (30/40 kW), 4 bar (60 -
115 kW). Refer to relevant British Standards and Codes of Practice
for installation of condensing boilers on sealed system. The heat
exchanger consists of aluminium - silicon alloy, which allows very
compact and lightweight boiler construction. The fully premix bur-
ner works in a modulating range of between 25 % and 100 %. There-
fore the boiler can adapt to the particular heat requirements of
thecircuit.The gas/airratiocontrol ensuresuniformCO2emissions
and low NOx. This is obtained by comparing the target boiler tem-
perature and actual boiler temperature. If there is a difference
between these two values then the internal microprocessor calcu-
lates a new fan speed. The change in fanspeed in turn changes the
combustion chamber static air pressure which is monitored by the
gas/air ratio control and the gas rate is adjusted thus maintaining
the correct gas to air ratio in the boiler. This ensures that a uniform

Safety
6 POTTERTONCOMMERCIAL
120-393 632.4 04.08 Fh
gas/air ratio is maintained over the total range of the boiler mo-
dulation, and that constant CO2values are achieved.
For optimum utilisation condensing boilers should be operated at
a low return temperature. However the PARAMOUNT two will also
work at designed temperatures of 70/50°C. In the condensing
mode as the return temperature is below the dew point (dew point
is 53°C at 8.5 % CO2).
They fulfil EN 483 and EN 677, Type C. Installation types B23, B33,
C13x, C33x, C43x, C63x. Emission value group G 61.
Category II2H3P.
2.3 Installations/Instructions
Before starting work a risk assessment should be carried out in the
boiler house and its access to ensure a safe installation and wor-
king environment. Any person installing or working on the boiler
must be qualified and attention is drawn to the mandatory require-
ments of C.O.R.G.I. registration for all gas installers.
Manual Handling: Any person or persons moving or lifting the boiler
or any part there of should be trained in manual handling techni-
ques and if necessary use suitable lifting equipment to reduce the
risk of injury to themselves or other people.
2.4 Regulations and standards
The installation should comply with relevant British Standard Spe-
cifications, Codes of Practice and current Building Regulations, to-
gether with any special regional requirements of the Local
Authorities, Gas undertaking and Insurance I.E.E. Regulations for
the Electrical Equipment of Buildings. The installation of the boiler
must be in accordance with the relevant requirements of:

4.1 Combustion air supply
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 applica-
tions.
Clean combustion air!
The PARAMOUNT two must only be installed in rooms with clean
combustion air. Under no circumstances must e.g. pollen or the li-
kes enter through the intake openings into the inside of the PARA-
MOUNT two.

4.2 Corrosion protection
The combustion air must be free from corrosive elements - espe-
cially fluorine and chlorine containing vapours which arefound, for
example, in solvents and cleaning agents, propellant gases etc.
When connecting boilers to under-floor heating systems, employ-
ing plastic pipe work which is not impervious to oxygen, heat ex-
changers must be used for separation purposes.
4.3 System water quality
To ensure the boiler heat exchanger remains in good condition it is
essential to condition and monitor the system water to the follo-
wing criteria:
– Water hardness: if the system fill water has a hardness in excess
of 259 mg/l (17,5°Clark) the water should be softened prior to
filling the system to ensure that excessive scaling does not oc-
cur within the heat exchanger.
– Water acidity: the system fill water should have pH value bet-
ween 7 - 8.3 to ensure corrosion of the heat exchanger does not
occur.
– Copper ions: the copper content of the system water should be
less than 0.05 mg/l. If large quantities of copper are present red
and black copper oxide Cu2O and CuO and grey/green copper
carbonate, CuCo2will be produced. Copper will corrode any
iron and aluminium within the system. A special water treat-
ment company should be consulted if in doubt.
4.4 Use of additives (e.g. hardness stabilsisers, frost protective agents, sealing agents)
If, in a special case, a need exists to use additives in a mixture
(e.g. hardness stabilser, frost protecion agent, sealing agent,etc.)
it has to be observed that the agents are compatible with each
other and the pH-value is not altered. Preferably, agents from the
same manufacturer should be used.
The instructions of the additive manufacturer have to be observed.
Released additives
Currently, the following agents have been approved by POTTERTON
Commercial:
– “Full heating protection“ from Fernox
– “Sentinel 100“ from GE Betz
As a single frost protection agent, also Tyfocor® L may be used.
