Related Documents
The installation of this boiler must be in ac-
cordance with the relevant requirements of
the Gas Safety (Installation & Use) Regula-
tions 1998 the Local Building Regulations, the
current l.E.E. Wiring Regulations, the by-laws
of the local water undertaking, and in Scot-
land, in accordance with the Building Stand-
ards (Scotland) Regulation. In Ireland the lo-
cal building regulations (IE).
It should be in accordance also with any rel-
evant requirements of the local authority and
the relevant recommendations of the follow-

4.2
Location of Appliance
The combination boiler may be installed in any
room or internal space, although particular
attention is drawn to the requirements of the
current l.E.E. Wiring Regulations, and in Scot-
land, the electrical provisions of the Building
Regulations applicable in Scotland, with re-
spect to the installation of the combination
boiler in a room or internal space containing a
bath or shower.
Where a room-sealed appliance is installed in
a room containing a bath or shower, any
electrical switch or appliance control, utilising
mains electricity, should be located in such a
position that it cannot be touched by a person
using the bath or shower.
The location chosen for the boiler must permit
the provision of a satisfactory flue and termi-
nation. The location must also permit an ad-
equate air supply for combustion purposes
and an adequate space for servicing and air
circulation around the boiler.
Where the installation of the boiler will be in an
unusual location special procedures may be
necessary and BS 6798:1987 gives detailed
guidance on this aspect.
Installation pipes should be fitted in accord-
ance with BS 6891:1988.
Pipework from the meter to the boiler must be
of adequate size. Pipes of a smaller size than
the boiler inlet connection should not be used.
The complete installation must be tested for
soundness as described in the above code.
N.B. If the gas supply for the boiler serves
other appliances ensure that an adequate
supply is available both to the boiler and the
other appliance when they are in use at the
same time.
4.4
Flue System
The terminal should be located where disper-
sal of combustion products is not impeded and
with due regard for the damage or discolora-
tion that might occur to building products in the
vicinity (see fig 4).
The terminal must not be located in a place
where it is likely to cause a nuisance.
In cold and/or humid weather water vapour
may condense on leaving the flue terminal.
The effect of such ‘steaming’ must be consid-
ered.
A compartment used to enclose the boiler
must be designed and constructed specifi-
cally for this purpose. An existing cupboard or
compartment may be used provided that it is
modified for this purpose.
Details of essential features of cupboard/ com-
partment design including airing cupboard in-
stallations are given in BS 6798:1987. This
appliance is not suitable for external installa-
tion.
4.3
Gas Supply
A gas meter is connected to the service pipe
by the gas supplier.
An existing meter should be checked, prefer-
ably by the gas supplier, to ensure that the
meter is adequate to deal with the rate of gas
supply required for all appliances it serves.
