In order to meet the Building Regulations

requirement to reduce the rate of accumulation
of scale in hard water areas, it is important
299

that the installer checks the hardness of the
148

incoming water supply.
If this exceeds 200ppm (mg/l), we recommend
that the factory fitted scale inhibitor is ordered
as an optional extra.
If it exceeds 300ppm (mg/l), we recommend the
use of a polyphosphate type of scale inhibitor.
This can also be ordered as an optional extra but
will need fitting on site by the installer.
Note:
If the summer towel rail circuit is required, this
will need to be a separate zoned circuit from the
heating circuit complete with its own time and
temperature controls.
The standard manual fill model BoilerMate A-
Class SP SOL appliance is shown. A ballvalve and
overflow are available as an optional extra at the
time of order. If required, these should be fitted
in the plain F&E cistern in a position to suit the
individual site conditions.
