SECTION 4 GENERAL REQUIREMENTS

4.0

SAFETY
Gas Safely (Installation and USE) Regulations,
1994, and amendments 1996.

It is law that all gas appliances are installed and ser-

viced by a Corgi registered installer     (identified  by

in accordance with the above regulations. Failure to
install appliances correctly could lead to prosecu-

tion. It is in your own interest, and that of safety, to

ensure the law is complied with. Check the boiler
and flue is the correct type for installation.

The installation of the boiler MUST also be in accor-

dance with the latest I.E.E (BS 7671) Wiring

Regulations, local building regulations, bye-laws of

the local water authority, the building regulations
and the Building standards (Scotland) and any rele-
vant  requirements of the local authority.

GENERAL INFORMATION
Both the user and the manufacturer rely heavily on
the installer, whose job it is to install the combination
boiler and connect it to a correctly designed heating
system. Acquaint yourself with the British Standards

concerning installation requirement. If you need
advice on any points your Ravenheat Technical
Services Office would be pleased to help. It is rec-
ommended that tools suitable for brass fittings are
used, and have a capability to accommodate hexa-
gon sizes up to 50 mms.

CODES OF PRACTICE/Fief: Documents

Detailed recommendations are contained in the fol-
lowing British Standard Codes of Practice:

IMPORTANT. These appliances are CE certificated

for safety and performance. It is, therefore, important
that no external control devices e.g. flue dampers,
economisers etc., are directly connected to this
appliance unless covered by these Installation and
Servicing Instructions or as otherwise recommend-
ed by Ravenheat in writing. If in doubt please
enquire.
Any direct connection of a control device not
approved by Ravenheat could invalidate the certifi-
cation and the normal appliance warranty. It could
also infringe the Gas Safety regulations and the
above regulations.

4.2.1

NOTE: The Ravenheat boiler has been tested and
examined by BG Technology Certification Services
and is certified to comply with the relevant require-
ments of ES 5258 Part 1 1986 BS 6332 Part 1 1983
and the relevant  BGK3.G. 1 agreements, also tests
based on BS 5286 Part 1,

If in doubt on any point please consult Ravenheat

Manufacturing Ltd.

LOCATION OF BOILER

Siting of Ravenheat RSF 82E Combi Boiler must be
as follows. The position of installation should be
within the building, unless otherwise protected by
suitable enclosure.
Adequate space for installation, servicing and aircir-
culation around boiler must be allowed for.
The Ravenheat RSF 82E Combi Boiler must be fit-
ted on a flat and vertical wall capable of adequately
supporting the weight of the boiler and any ancillary
equipment.
The appliance may be installed on a combustible
wall subject to the requirements of the Local

Authority and Building Regulations.

CLEARANCES AROUNDTHE APPLIANCE

The following minimum free spaces, required for

installation inspection and servicing, must be left
around the boiler
18 inches (450 mm) in front
5 inches (120 mm) above
6 inches (150 mm) below
3 inches (75 mm) on each side

1 inch (25 mm) in front when installed in a cupboard.

IMPORTANT NOTICE

If the combination boiler is to be fitted in a timber

framed building it should be fitted in accordance with
the British Gas Publication Guide for Gas installa-
tions in Timber Frame Housing Reference DM2. If in
doubt advice must be sought from the local gas sup-
plier.The combination boiler 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
provisions of the Building Regulations applicable in
Scotland, with respect to the installation of the com-
bination 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 so situated that it cannot be touched by a
person using a bath or shower.
A compartment used to enclose the combination
boiler MUST be designed and constructed specifi-
cally for this purpose. An existing cupboard, or com-
partment, may be used provided it is modified
accordingly. Samples of the RSF 82E combination

boiler have been examined by B.G. Technology
Notified Body, and is certified to comply with the

essential requirements of the Gas Appliance

Directive 90/396/EEC, the Low Voltage Directive

72/23/EEC and shows compliance with the Electro

Magnetic Compatibility Directive 89/336/EEC and

are therefore permitted to carry the CE Mark.
The appliance has been tested and approved by the
WRc as meeting the requirements of G3 and L of the

Building regulations and water Bylaws Scheme -

Approved Products.
