2.5.2 Installation site
The location chosen for the boiler must permit the provi-
sion of a satisfactory flue termination. The location must
also provide adequate space for servicing and air circula-
tion around the boiler.
Before commencement of any works the installer should
carry out a full risk assessment in accordance with Health
and Safety executive regulations.
The boiler may be installed in any room, although particular
attention is drawn to the requirements of BS 7671 (IEE Reg-
ulations), the electrical provisions of the Building Regula-
tions (Scotland) and in IE the current edition of IS 813 and
the current ETCI rules, in respect of the installation of a
boiler in a room containing a bath or shower.
In case of installation of the boiler in an unusual location,
special procedures may be necessary and BS 5546 and
BS 6798 give detailed guidance on this aspect. The boiler
must be mounted on a flat, vertical wall, which must be suf-
ficiently robust to take the weight of the boiler.
The boiler may be installed on a combustible wall, subject
to the requirements of the Local Authorities and Building
Regulations. A compartment used to enclose the boiler
must be designed and constructed specifically for this pur-
pose. (An existing cupboard or compartment may be used
provided that it is modified for the purpose). Details of
essential features of cupboard/compartment design includ-
ing airing cupboard installations are given in BS 6891. In IE
the current edition of IS 813.
i
If the boiler is to be installed in an airing
cupboard it is not required to separate the
boiler with a non-combustible partition. However
installation and servicing clearances must be
maintained, and the boiler kept clear of any
clothing.
