Page: 5 / 76

2.1 STATUTORY REQUIREMENTS
GAS SAFETY (INSTALLATION AND USE)
REGULATIONS (as amended). It is the law
that all gas appliances are installed by a reg-
istered person, in accordance with the
above regulations. Failure to install appli-
ances correctly could lead to prosecution. It
is in your own interest, and that of safety, to
ensure that the law is complied with.
In addition to the above regulations, this
appliance must be installed in accordance
with the current IEE Wiring Regulations (BS
7671), Local Building Regulations, the
Building Standards (Scotland) (Consolidation)
Regulations, Byelaws of the local water
undertaking, and Health and Safety
Document No 635 ‘The Electricity at Work
Regulations 1989’.
It should also be in accordance with the rel-
evant recommendations in the current edi-
tions of the following British Standards and
Codes of Practice: BS5449, BS5546,
BS5440:1, BS5440:2, BS6798, BS6891,
and BG.DM2, BS7074, and BS5482 for
propane installations.
Manufacturer’s instructions must NOT be
taken in any way as over-riding statutory
obligations.
2.2 BOILER POSITION
In siting the combination boiler, the following
limitations MUST be observed:
– The boiler is not suitable for external
installation. The position selected for
installation should be within the building,
unless otherwise protected by a suitable
enclosure, and MUST allow adequate
space for installation, servicing, and
operation of the appliance, and for air
circulation around it (section 2.4).
– This position MUST allow for a suitable
flue termination to be made. The combi-
nation boiler must be installed on a flat
vertical wall which is capable of support-
ing the weight of the appliance, and any
ancillary equipment.
– If the combination boiler is to be fitted in
a timber framed building it should be fit-
ted in accordance with the British Gas
publication Guide for Gas Installations In
Timber Frame Housing, Reference
DM2. If in doubt, advice must be sought
from the gas supplier.
– If the appliance is installed in a room
containing a bath or shower, any electri-
cal switch or control utilising mains elec-
tricity must be so situated that it cannot
be touched by a person using the bath
or shower. Attention is drawn to the
requirements of the current I.E.E. Wiring
Regulations (BS 7671), and in Scotland
the electrical provisions of the Building
Regulations applicable in Scotland.
– A compartment used to enclose the
appliance MUST be designed and con-
structed specifically for this purpose. An
existing cupboard, or compartment,
may be used provided it is modified
accordingly.
– Where installation will be in an unusual
location, special procedures may be nec-
essary. BS6798 gives detailed guidance
on this aspect.
2.3 FLUE TERMINAL POSITION
Detailed recommendations for flue installa-
tion are given in BS5440:1. The following
notes are for general guidance:
– The boiler MUST be installed so that the
terminal is exposed to the external air.
– It is important that the position of the
terminal allows free passage of air
across it at all times.
– It is ESSENTIAL TO ENSURE, in practice
that products of combustion discharg-
ing from the terminal cannot re-enter
the building, or any other adjacent build-
ing, through ventilators, windows, doors,
other sources of natural air infiltration,
or forced ventilation/air conditioning. If
this does occur, the appliance MUST be
turned OFF IMMEDIATELY and the gas
supplier consulted.
– The minimum acceptable dimensions
from the terminal to obstructions and
ventilation openings are specified in fig. 4.
– If the terminal discharges into a path-
way or passageway check that com-
bustion products will not cause nui-
sance and that the terminal will not
obstruct the passageway.
– Where the lowest part of the terminal is
fitted less than 2 m (78 in) above
ground, above a balcony or above a flat
roof to which people have access, the
terminal MUST be protected by a pur-
pose designed guard. Terminal guards
are available from Quinnell, Barrett, and
Quinnell, Old Kent Road, London. State
model C2, (G.C. Part No 382946).
– Where the terminal is fitted within 850
mm (34 in) of a plastic or painted gutter,
or 450 mm (18 in) of painted eaves, an
aluminium shield at least 1,500 mm (59
in) long must be fitted to the underside of
