Installation & Servicing
Where a room-sealed appliance is installed in a room
containing a bath or shower then the appliance and any
electrical switch or appliance control utilising mains electricity
should be so situated that it cannot be touched by a person
using the bath or shower.
Where installation will be in an unusual location, special
procedures may be necessary and BS.6798 gives detailed
guidance on this aspect.
Compartment Installations
A compartment used to enclose the boiler MUST be designed
and constructed specially for this purpose.
An existing cupboard or compartment may be used, providing it
is modified for the purpose.
In both cases details of essential features of cupboards/
compartment design, including airing cupboard installation,
are to conform to the following:
!
!
!
!
!
BS. 6798.
!
!
!
!
!
The position selected for installation MUST allow
adequate space for servicing in front of the boiler
and for air circulation around the boiler.
Side clearance is only necessary for installation. The
amount of side clearance will depend upon the type of
connection used.
!
This position MUST also permit the provision of a
satisfactory flue termination.
!
For the minimum clearances required for safety and
subsequent service see Frame 2.
SAFE HANDLING OF SUBSTANCES
Care should be taken when handling the boiler insulation panels,
which can cause irritation to the skin. No asbestos, mercury or
CFCs are included in any part of the boiler.
LOCATION OF BOILER
The boiler must be installed on a flat and level floor, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.
The boiler may be fitted on a combustible floor.
Insulation is not necessary, unless required by the local authority.
The boiler must not be fitted outside.
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 Engineers document
IGE/UP/7 : 1998.
Bathrooms
The boiler may be installed in any room or internal space,
although particular attention is drawn to the requirements of the
current I.E.E. (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. For
Ireland reference should be made to the current ETCI rules for
electrical installations and I.S. 813: 2002.
2 FLOOR MOUNTING AND BOILER CLEARANCES
Flammable materials must not be placed in close proximity to the appliance. Materials
giving off flammable vapours must not be stored in the same room as the appliance.
Floor mounting
1.
The floor must be flat, level and of suitable load
bearing capacity.
2.
The back of the boiler may be fitted up to the wall.
Boiler clearances
The minimum overall dimensions of the space in
which the boiler is to operate and to facilitate
servicing are as follows:-
Additional space will be required for installation,
depending upon site conditions.
IMPORTANT.
In order to facilitate gas connection, a clearance of at
least 100 mm (4") must be available at either the left
hand side or the right hand side DURING
installation. Refer to Frame 39.
In addition a MINIMUM clearance of 533 mm (21")
