Regulations and directives
It is a requirement that all gas appliances are installed and
serviced by a CORGI registered installer in accordance with
the regulations. Failure to install appliances correctly could
lead to prosecution. It is in your own interest, and that of safety,
to ensure the law is complied with.
The installation must also be in accordance with the latest
I.E.E (
BS.7671
) Wiring Regulations, water regulations, the
building regulations and the Building Standards (Scotland) and
any relevant requirements of the local authority.
It is a requirement and in your own interest, and that of safety
that this boiler must be installed by a CORGI registered
installer, in accordance with the relevant requirements of the
current Gas Safety (Installation and Use) Regulations, The
Building Regulations, current I.E.E. Wiring Regulations and
the relevant British Standard Codes of Practise.
Detailed recommendations are contained in the following
British Standard Codes of Practice:
BS. 5440:1
Flues (for gas appliances of rated input not
exceeding 70 kW).
BS. 5440:2
Ventilation (for gas appliances of rated input not
exceeding 70 kW).
BS. 5449
Forced circulation hot water systems.
BS. 5546
Installation of gas hot water supplies for domestic
purposes (2nd. family Gases).
BS. 6798
Installation of gas fired hot water boilers of rated
input not exceeding 60 kW.
BS. 6891
Low pressure installation pipes.
BS. 7593: 1992:
Code of practice for treatment of water in
domestic hot water central heating
systems.
IGE/UP/1b
Tightness testing and purging domestic sized gas
installations.
Health and & Safety Document No. 635.
The Electricity at Work Regulations, 1989.
The manufacturer's notes must not be taken, in any way, as
overriding statutory obligations.
The design and construction of the Buderus wall-mounted
condensing gas system boiler 500-24/S conforms to the basic
specifications listed in the European directive governing gas-
fired appliances 90/396/EEC, and with respect to EN 625,
EN 483 and EN 677.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it should
be fitted in accordance with the Institute of Gas Engineering
document
IGE/UP/7:1998 and BS 5440:1.
Bathroom Installations
This appliance is rated IP X4D.
The boiler may be installed in any room or internal space,
although particular attention is drawn to the requirements of
the current IEE (
BS.7671
) Wiring Regulations and, in
Scotland, the electrical provisions of the building regulations
applicable in Scotland, with respect to the installation of the
boiler in a room or internal space containing a bath or shower.
If the appliance is to be installed in a room containing a bath or
shower then, providing water jets are not going to be used for
cleaning purposes (as in communal baths/showers), the
appliance can be installed in Zone 3, as detailed in
BS.7671
.
Compartment Installations
A compartment used to enclose the boiler should be designed
and constructed especially for this purpose.
An existing cupboard or compartment may be used, provided
that it is modified for the purpose.
In both cases, details of essential features of cupboard/
compartment design, including airing cupboard installation,
are to conform to the following:
BS 6798
(No cupboard ventilation is required - see 'Air Supply'
for details).
It is not necessary to have a purpose-provided air vent in the
room or internal space in which the boiler is installed. Neither
is it necessary to ventilate a cupboard or compartment in which
the boiler is installed, due to the low surface temperatures of
the boiler casing during operation; therefore the requirements
of
BS 6798
,
Clause 12
, and
BS 5440:2
may be disregarded.
NOTE
Observe the corresponding technical rules and
the building supervisory and statutory
regulations when installing and operating the
system.
WARNING!
Keep the burner-control unit housing CLOSED
when working on water-bearing components.
NOTE
The heating boiler is designed exclusively for
heating water as part of a central heating system
and/or hot-water system.
NOTE
For optimum, long-term reliable functioning of
the heating boiler, and in order to be able to
claim under the terms of the manufacturer's
warranty, the heating boiler must be inspected
and maintained at least once a year (under
normal operating conditions) by an officially
recognized installation and service engineer.
The term "normal operating conditions" means
that the heating boiler is used to provide central
heating and/or hot water to no more than one
single-family dwelling.
NOTE
When instructions aren’t followed, warranty
expires.
NOTE
Condensing boilers work more efficient if the
CH flow/return temperature is as low as
possible.
