3.1
RELATED DOCUMENTS
The installation of this boiler must be in accordance
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 Build-
ing Standards (Northern Ireland) Regulations.
It should be in accordance also with any relevant
requirements of the local authority and the relevant
recommendations of the following British Standard
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 provi-
sions 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 ad-
equate 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/cupboard may
be utilised provided that it is modified to suit.
Details of essential features of compartment/cup-
board design including airing cupboard installations
are given in BS 6798. This appliance is not suitable
for external installation.

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 BS6891.
If the gas supply serves more than one appliance,
it must be ensured that an adequate supply is main-
tained to each appliance when they are in use at
the same time.
3.4
FLUE SYSTEM
The terminal should be located where the dispersal
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).
In cold and/or humid weather, water vapour may
condense on leaving the terminal; the effect of such
pluming must be considered.
If installed less than 2m above a pavement or
platform to which people have access (including
balconies or flat roofs) the terminal must be pro-
tected by a guard of durable material. The guard
must be fitted centrally over the terminal. Refer to
BS 5440 Part 1, when the terminal is 0.5 metres (or
less) below plastic guttering or 1 metre (or less)
below painted eaves.
