6.0SYSTEM DETAILS

6.1Information

1.The Potterton Performa 24 Eco HE Condensing Combination Boiler 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.

6.2Central Heating Circuit

1.The appliance is suitable for fully pumped SEALED SYSTEMS ONLY.

Treatment of Water Circulating Systems

•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.

•When fitting new systems flux will be evident within the system, which can lead to damage of system components.

•All systems must be thoroughly drained and flushed out. Using for example Betz-Dearborn Sentinel X300 or X400 or Fernox Superfloc Universal Cleanser which should be used following the flushing agent manufacturer’s instructions.

•System additives - corrosion inhibitors and flushing agents/descalers should be suitable for aluminium and comply to BS7593 requirements, e.g. Betz-Dearborn Sentinel X100 and Fernox-Copal which should be used following the inhibitor manufacturer’s instructions.

Failure to flush and add inhibitor to the system will invalidate the appliance warranty.

•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.)

•For information or advice regarding any of the above contact the Potterton Helpline.

6.3Bypass

1.The boiler is fitted with an automatic integral bypass.

6.4System Control

1.The boiler is designed for use in a heating system that incorporates external controls, i.e. a minimum of a timer device.

2.An integral electro-mechanical or electronic timer is available as an optional extra.

3.For optimum operating conditions and maximum economy the fitting of a programmable thermostat is recommended.
