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
• 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 Technical Enquiries.
6.3
Bypass
1. The boiler is fitted with 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.
