INSTALLATION REQUIREMENTS

The following limitations MUST be observed when siting the boiler:
a) The boiler is not suitable for external installations. The position
selected for installation should be within the building, unless
otherwise protected by a suitable enclosure, and MUST allow
adequate space for installation, servicing and operation of the
appliance, and for air circulation around it (Section 2.3 and
3.4).
b) This position MUST allow for a suitable flue system and
terminal position. The boiler must be installed on a flat vertical
wall which is capable of supporting the weight of the
appliance and any ancillary equipment.
c) If the boiler is to be fitted in a timber framed building it
should be fitted in accordance with the British Gas
publication ‘Guide for Gas Installations In Timber Frame
Housing’, Institute of Gas Engineers document IGE/UP-7. If
in doubt, advice must be sought from the Local Gas
Supplier.
d) The appliance is approved to a protection rating of IP20.
Therefore if the appliance is to be installed in a room
containing a bath or a shower, any electrical switch or
control utilising mains electricity must be so situated that it
cannot be touched by a person using the bath or a shower.
Attention is drawn to the requirements of the current
BS7671 (I.E.E Wiring Regulations, and in Scotland the
electrical provisions of the Building regulations applicable
in Scotland.
