applicable in Scotland, with respect to the installation of the boiler in a room or internal
space containing a bath or shower.
Where a room-sealed appliance is installed in a room containing a bath or shower, any
electrical switch or appliance control, utilising mains electricity, should be so situated that
it cannot be touched by a person using the bath or shower. The C36 Combi and C36P
Combi are classified as IP20 (IPX0) and are therefore suitable for installation in Zone 3
areas, unless subject to hose down.
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 C36 Combi can be located virtually anywhere desired provided that all
[NB: Refer to
Section 3.8.3]
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 Connections
The boiler must be connected to a permanent 230V ~ 50Hz supply, fused at 3A.
The boiler has provision to receive a 230VAC switched live signal from a
room thermostat/time clock. 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. DHW demand will always take
priority over heating demand. Wiring external to the boiler must be in
accordance with current I.E.E wiring regulations and local regulations.
