a Caution!
The appliance must be installed and serviced by
a competent person approved at the time by
the Health and Safety Executive as stated in
the Gas Safety (Installation and Use) Regula-
tions 1998. In IE, the installation must be in
accordance with the current edition of I.S.813
'Domestic Gas Installations', the current Build-
ing Regulations and reference should be made
to the current ETCI rules for electrical installa-
tion.
Caution!
a
When tightening or slackening screwed connec-
tions always use suitable open-ended spanners
(not pipe wrench, or extensions, etc.). Incorrect
use and/or unsuitable tools can lead to damage
being caused (e.g. gas or water leakage)!
3.3

Installation site

The location chosen for the boiler must permit the provision
of a satisfactory flue termination. The location must also pro-
vide adequate space for servicing and air circulation around
the boiler. The boiler may be installed in any room, although
particular attention is drawn to the requirements of BS 7671
(IEE Regulations), the electrical provisions of the Building
Standards (Scotland) Regulations, and in IE the current edi-
tion of IS 813 and the current ETCI rules, in respect of the in-
stallation of a boiler in a room containing a bath or shower.
h Note!
If a room sealed boiler is installed in a room
with a bath or shower, electrical switches or
boiler controls using the mains power supply
must be placed at locations that cannot be
reached by the person in the bath or shower.
If the boiler is installed in an unusual location, special proce-
dures may be necessary and BS 5546 and BS 6798 give
detailed guidance on this aspect. The boiler must be mount-
ed on a flat, vertical wall, which must be sufficiently 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 purpose. (An existing cupboard or com-
partment may be used provided that it is modified for the
purpose). Details of essential features of cupboard/compart-
ment design including airing cupboard installations are given
in BS 6798. If the boiler is to be fitted in a timber framed
building, it should be fitted in accordance with Institute of
Gas Engineers Publication IG/UP/7 Edition 2 "Gas installa-
