3.4 Electricity Supply
230V ~ 50Hz via a fused double pole switch with
a contact separation of at least 3 mm in both
poles.
There must be only one common isolator for the
boiler and its control system, it must provide
complete electrical isolation and be fitted
adjacent to the boiler.
There is no method of isolating the boiler at the
user interface.
The power cable to the boiler must be 4-core to
supply permanent live, neutral, earth and
switched live.
Electrical installation should be in accordance
with BS7671.
WARNING: THIS BOILER MUST BE EARTHED AND
CORRECTLY POLARISED.
3.5 Location of Boiler
The boiler must be mounted on a flat wall which
is sufficiently robust to take the weight of the
boiler.

The boiler should be fitted within the building
unless otherwise protected by a suitable
enclosure.
Clearances
The boiler requires only the clearances shown
on Page 7, after installation.
Combustible Wall
The boiler is suitable for installation to a
combustible wall e.g. wood cladding, provided
that the flue duct is not closer than 25 mm to
combustible material. A metal sleeve should be
installed to surround the flue duct to provide a
25 mm annular space. Further guidance is
given in BS5440: Pt 1.
Timber Frame
If the boiler is to be fitted into a building of
timber frame construction then reference must
be made to the current edition of Institution of
Gas Engineers Publication IGE/UP/7/ (Gas
Installation in Timber Framed Housing).
Bath or Shower Room
If the boiler is fitted in a room containing a bath or shower, it
cannot be fitted in zone 0, 1 or 2 (Figs. A & B shows zone
dimensions for a bathtub. For other examples refer to the

to the relevant requirements.
In GB this is the current I.E.E. Wiring Regulations and
Building Regulations.

(Gas Installations in Timber Framed Housing).
Cupboard or Compartment
A cupboard or compartment used to enclose the boiler must
be designed and constructed specifically for this purpose. An
