6.8 Existing systems.
All re-circulatory water systems are subject to
corrosion unless an appropriate water treatment is
applied. To prevent the risk of accumulated
corrosion sludge, within an existing system,
causing boiler noise and circulation problems along
with possible pump and valve damage, the existing
heating systems must be thoroughly flushed to
ensure that all sludge and debris are removed prior
to installation of the boiler.
Where a cleaning agent is used for this purpose,
only Sentinel X400 is recommended.
Note
. When, after flushing and cleaning of the
system has taken place, there is any possibility of
any debris remaining in the system, it is
recommended that a 'Y' strainer is fitted on the
boiler

pipe.
