6.2 Central 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 upgrading existing systems that exhibit evidence of
sludging, it is advisable to clean the system prior to treatment in
order to remove any sludge and reduce the likelihood of these
deposits damaging new components.
• 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. The
recommended flushing and cleansing agents are Betz-Dearborn
Sentinel X300 or X400 and Fernox Superfloc Universal Cleanser
which should be used following the flushing agent manufacturer's
instructions.
• System additives - corrosion inhibitors and flushing
agents/descalers should comply to BS7593 requirements. The
only system additives recommended are 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
