Installation
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.
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.
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.

including airing cupboard installation, are to conform to the

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. Where side units are modified to facilitate
installation then no clearance is required.
z
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.
GAS SUPPLY
The local gas supplier should be consulted, at the installation
planning stage, in order to establish the availability of an
adequate supply of gas. An existing service pipe must NOT be
used without prior consultation with the local gas supplier.
The boiler is to be installed only on a gas supply with a
governed meter.
