GENERAL REQUIREMENTS
This appliance must be installed by a competent
person in accordance with the Gas Safety (Instal-
lation & Use) Regulations.
3.1
RELATED DOCUMENTS
The installation of this boiler must be in accord-
ance with the relevant requirements of the Gas
Safety (Installation & Use) Regulations, the local
building regulations, the current I.E.E. wiring
regulations, the bylaws of the local water
undertaking, the Building Standards (Scotland)
Regulation and Building Standards (Northern
Ireland) Regulations.
It should be in accordance also with any relevant
requirements of the local authority and the relevant

Codes of Practice.
3.2
LOCATION OF APPLIANCE
The appliance may be installed in any room or
internal space, although particular attention is
drawn to the requirements of the current I.E.E.
wiring regulations, and in Scotland, the electrical
provisions of the Building Regulations, with
respect to the installation of the appliance in a
room or internal space containing a bath or shower.
When an appliance is installed in a room or
internal space containing a bath or shower, the
appliance or any control pertaining to it must not
be within reach of a person using the bath or
shower.
The location chosen for the appliance must permit
the provision of a safe and satisfactory flue and
termination. The location must also permit an
adequate air supply for combustion purposes
and an adequate space for servicing and air
circulation around the appliance.
Where the installation of the appliance will be in
an unusual location special procedures may be
necessary, BS 6798 gives detailed guidance on
this aspect.
A compartment used to enclose the appliance
must be designed and constructed specifically
for this purpose. An existing compartment/cup-
board may be utilised provided that it is modified
to suit.
Details of essential features of compartment/
cupboard design, including airing cupboard in-
stallations, are given in BS 6798. This appliance
is not suitable for external installation.
3.3
GAS SUPPLY
The gas meter – as supplied by the gas supplier
– must be checked to ensure that it is of adequate
size to deal with the maximum rated input of all
the appliances that it serves. Installation pipes
must be fitted in accordance with BS 6891.
Pipe-work from the meter to the appliance must
be of adequate size. Pipes of a smaller size than
the appliance gas inlet connection must not be
used.
The installation must be tested for soundness in
accordance with BS 6891.
If the gas supply serves more than one appliance,
it must be ensured that an adequate supply is
maintained to each appliance when they are in
use at the same time.
3.4
FLUE SYSTEM
The terminal should be located where the disper-
sal of combustion products is not impeded and
with due regard for the damage and discoloration
that may occur to building products located
nearby.
The terminal must not be located in a place where
it is likely to cause a nuisance (see fig. 4).
Water vapour will condense on leaving the flue
terminal, the effect of such pluming must be
considered.
