STRATA1
17.1 water treatment
system cleaning
The entire system must be thoroughly cleansed and flushed to remove debris, flux residues etc before
opening the boiler isolation valves & flooding the boiler. Particular care must be taken where the Strata
boiler is being retro-fitted into an old/existing system, as system silt or magenite can be very damaging to
the new boiler.
Following cleansing and flushing the system must be dosed with a good quality water treatment to
prevent corrosion and the formation of scale.
Failure to observe these requirements will render the guarantee on the product
void. Cleansing, flushing and water treatment must be carried out in accordance
with the requirements of BS 7593:1992.

17.2 inclusion
of strainers
The return pipework must include some method of filtering or straining. The Filter or strainer must be
fitted with isolation valves to allow easy cleaning with the minimum amount of water loss and water
replenishment.
17.3 low water
pressure protection
A low water pressure switch must be included within the system design and interlocked to the boiler
to shut the boiler down in the event of the water pressure falling below 0.5 bar.
