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.
The Keston Qudos 28h 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. Before locating the boiler near a living
space consider whether the sounds generated by the boiler will be objectionable. The
boiler may be located within a cupboard enclosure to reduce noise levels if located within
a living space. LPG boilers must not be installed in a cellar.

ELECTRICAL
3.4.1
Electrical Connections
The boiler must be connected to a permanent 230V ~ 50Hz supply, fused at 3A.
The boiler can be wired to a single switched live 230VAC signal input.
However, the boiler has TWO thermostats, and will therefore accept up to
TWO switched live 230VAC signal inputs, such as heating and hot water.
Alternatively, a Keston Room Controller can be connected directly, via two
core low voltage cable, to the terminals marked “OT”. The Keston Room
Controller will then provide fully room compensated control to ensure the
boiler output is matched to the rooms requirements at optimum boiler
efficiency. This is only recommended for heating only applications. Further,
the boiler can be driven by an external 0-10VDC input.
Wiring external to the boiler must be in accordance with current I.E.E wiring
regulations and local regulations.
The method of connection to the mains electricity supply
must
facilitate complete
electrical isolation of the boiler, preferably by the use of a fused, unswitched three
pin plug and a shuttered socket-outlet, both complying with the requirements of
BS 1363. There must be only one common method of isolation for the boiler and
its control system.
