6.0 System Details

6.1 Information
1. The Potterton Gold Combi HE
is a 'Water Byelaws Scheme - Approved Product'.
To comply with the Water Byelaws your attention is drawn to the
following installation requirements and notes (IRN).
a) IRN 001 - See text of entry for installation
requirements and notes.
b) IRN 302 - Byelaw 14.
2. Reference to the WRc publications, 'Water fittings and materials
directory' and 'Water supply byelaws guide' give full details of
byelaws and the IRNs.
6.2 Central Heating Circuit
1. The appliance is suitable for fully pumped SEALED SYSTEMS
ONLY.
Treatment of Water Circulating Systems
1. All recirculatory water systems will be subject to corrosion
unless an appropriate water treatment is applied. This means
that the efficiency of the system will deteriorate as corrosion
sludge accumulates within the system, risking damage to pump
and valves, boiler noise and circulation problems.
2. When fitting new systems flux will be evident within the
system, which can lead to damage of system components.
3. All systems must be thoroughly drained and flushed out using,
for example, Sentinel X300 or X400 or Fernox F3. They should
be used following the flushing agent manufacturer's instructions.
4. System additives - corrosion inhibitors and flushing
agents/descalers should comply to BS7593 requirements, e.g.
Sentinel X100 and Fernox MB-1 which should be used following
the inhibitor manufacturer's instructions.
5. Full instructions are supplied with the products, for further
information contact Sentinel (0800 389 4670) or Fernox
(0870 870 0362)
Failure to flush and add inhibitor to the system will invalidate
the appliance warranty.
6. It is important to check the inhibitor concentration after
installation, system modification and at every service in
accordance with the manufacturer's instructions. (Test kits are
available from inhibitor stockists.)
7. For information or advice regarding any of the above contact
Technical Enquiries.
6.3 Bypass
1. The boiler utilises the primary side of the DHW plate heat
exchanger as an automatic integral bypass.
6.4 System Control
1. A 24 hour electro - mechanical timer is supplied fitted to the
boiler.
2. Further external controls (e.g. room thermostat) should be
fitted to optimise the economical operation of the boiler.
