Danger! Absolutely observe the following safety instructions!
Otherwise, you may endanger yourself and others.
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.
Commissioning must only be carried out by personnel approved 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).
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
the circuit. The gas/air ratio control ensures uniform CO
and low NO . This is obtained by comparing the target boiler tem-
x
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 fan speed 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
