The following limitations MUST be observed when siting the boiler:
a) The boiler is not suitable for external installation. The position
selected for installation should be within the building, unless
otherwise protected by a suitable enclosure, and MUST allow
adequate space for installation, servicing, and operation of
the appliance, and for air circulation around it. (Section 2.3
and 3.4)
b) This position MUST allow for a suitable flue system and
terminal position. (Section 2.6 and 3.3) The combination
boiler must be installed on a flat vertical wall which is capable
of supporting the weight of the appliance and any ancillary
equipment.
c) If the combination boiler is to be fitted in a timber framed
building it should be fitted in accordance with the British Gas
publication ‘Guide for Gas Installations In Timber Frame
Housing’, Institute of Gas Engineers document IGE/UP-7. If in
doubt, advice must be sought from the Local Gas Supplier.
d) If the appliance is to be installed in a room containing a bath
or a shower, any electrical switch or control utilising mains
electricity must be so situated that it cannot be touched by a
person using the bath or shower. Attention is drawn to the
requirements of the current l.E.E. Wiring Regulations
(BS7671), and in Scotland the electrical provisions of the
Building Regulations applicable in Scotland.
e) A compartment used to enclose the appliance MUST be
designed and constructed specifically for this purpose. An
existing cupboard, or compartment, may be used provided it
is modified accordingly. BS 6798 gives details of the essential
features of cupboard / compartment design, including airing
cupboards.
f ) Where installation will be in an unusual location, special
procedures may be necessary. BS 6798 gives detailed
guidance on this aspect.
