SECTION 4A GENERAL REQUIREMENTS (EIRE)
This appliance must be installed by a competent person in
accordance with and defined by, the Standard Specification
(Domestic Gas Installations) Declaration (I.S. 813).
4A.1
Related Documents
The installation of this boiler must be in accor-
dance with the relevant requirements of the local-
building regulations, the current ETCI National
Rules for Electrical Installations, and the bylaws
of the local water undertaking. It should be in
accordance also with any relevant requirements
of the local and/or district authority.
4A.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 ETCI
National Rules for Electrical Installations, and I.S.
813, Annex K. 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 per-
mit 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 circula-
tion around the appliance. Where the installation
of the appliance will be in an unusual location
special procedures may be necessary, refer to
I.S. 813 for 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. This
appliance is not suitable for external installation.
4A.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 I.S. 813. 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 I.S. 813. 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.
4A.4
Flue System
wThe terminal should be located where the
dispersal of combustion products is not impeded
and with due regard for the damage and discolo-
ration 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 (refer
to I.S. 813 for guidance on permitted locations
and minimum distances of flue terminals). Water
vapour will 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 I.S. 813, when the terminal is 0.5 metres
(or less) below plastic guttering or 1 metre (or
less) below painted eaves.
4A.5
Air Supply
The following notes are intended for general gui-
dance.
The room sealed fan flued boiler does not requi-
re a permanent air vent for combustion air supply.
Where installed in a cupboard or compartment
ventilation is required for cooling.
The table above gives the recommended mini-
mum effective areas of such air vents.
4A.6
Water Circulation
Specific recommendations are given in I.S. 813.
The following notes are for general guidance only.
4A.6.1
Pipework
It is recommended that copper tubing be used in
conjunction with soldered capillary joints. Where
possible pipes should have a gradient to ensure
air is carried naturally to air release points and
that water flows naturally to drain cocks. Except
where providing useful heat, pipes should be
insulated to avoid heat loss and in particular to
avoid the possibility of freezing. Particular atten-
tion should be paid to pipes passing through ven-
tilated areas such as under floors, loft space, and
void areas.
4A.6.2
Automatic By-pass
The appliance has a built-in automatic by-pass.
However it may be necessary to fit an external
bypass should the design of the heating system
require such. In any case, the design of the
system should be such that it prevents boiler
cycling’.
4A.6.3
Drain Cocks
These must be located in accessible positions to
facilitate draining of the appliance and all water
pipes connected to the appliance.
4A.6.4
Air Relase Points
These must be positioned at the highest points in
the system where air is likely to be trapped. They
should be used to expel trapped air and allow
complete filling of the system.
