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, Sentinel X300 or X400 or Fernox F3. They should be used following the flushing agent manufacturer’s instructions.

•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.

•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.

•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 Technical Enquiries.

6.3Bypass

1.The boiler utilises the primary side of the DHW plate heat exchanger as 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.Suitable timer kits are available as optional extras.

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