DESIGN
INTRODUCTION
gulley or else issue externally at ground level.
High level termination from walls or on roofs
could cause injury to people or animals below
if the valve were to release scalding water and
steam.
The pipe leading to the safety device and
the collector should be of rigid and non-
deformable construction, without any possibility
of restriction or disclosure by any other fitted
component.
In order to meet the Building Regulations
requirement to reduce the rate of accumulation
of scale in hard water areas, it is important
that the installer checks the hardness of the
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.
