System Water Quality
Water Treatment, System Cleaning (BS 7592: 2006)
The entire primary system MUST be thoroughly cleaned 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 Streamline boiler is being retro-fitted
into an old/existing system, as system silt or magnetite can be very damaging to the new
boiler.
Following cleaning 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 WARRANTEE ON THE APPLIANCE
VOID.
Cleaning, flushing and water treatment must be carried out in accordance with the
requirements of BS 7593:1992, prior to commissioning the boiler.
Repeated draining and refilling of the system, without replenishment of water
treatment, must be avoided, as this is very damaging to the boiler. The boiler must not
operate without the system water being correctly and adequately treated, and
maintained, with an appropriate level of corrosion inhibitor.

Care With The Use of Solder Flux

followed with regards to use in conjunction with Stainless Steel.
