Notes.
1. It is most important that the correct concentration of the water
treatment products is maintained in accordance with the
manufacturers’ instructions.
2. If the boiler is installed in an existing system any unsuitable
additives MUST be removed by thorough cleansing. BS
7593:2006 details the steps necessary to clean a domestic heating
system.
3. In hard water areas, treatment to prevent lime scale may be
necessary - however the use of articially softened water is NOT
permitted.
4. Under no circumstances should the boiler be red before the
system has been thoroughly ushed.
