POSITION
The Keston is not suitable for external
installation. The boiler may be installed
in any room or internal space, although
particular attention is drawn to the
requirements of the current IEE Wiring
Regulations and, in Scotland, the
electrical provisions of the
Building Regulations applicable in
Scotland, with respect to the
installation of the boiler in a room
or internal space containing a
bath or shower.
Compartment installation is
permitted - such compartments
must be constructed in
accordance with BS 6798.
The wall on which the boiler is
mounted must be of suitable load
bearing capacity and must be
non-combustible.
Important : It is not
recommended to install the boiler
on a studded wall or similar - it is
possible that the vibration from
the fan would be amplified and
transmitted to other parts of the
property.
The Keston can be located
virtually anywhere desired
provided that all regulations are
complied with. Because of the
boiler's compact size and venting
flexibility, the installation is not
limited to a boiler room setting.
