Installation
The boiler must be mounted on a flat wall which is sufficiently robust to take
the weight of the boiler. If the wall is of combustible material it must be
protected by a sheet of non-combustible material of thickness not less than 25
mm (1 in).
Note: If the boiler is to be fitted into a house of timber frame construction,
advice is available from your trade organisation or local Gas Region.
The boiler is designed for use with an open vented central heating system
and/or indirect domestic hot water system. IT MUST NOT BE CONNECTED
TO A DIRECT CYLINDER.
The boiler may be installed in any room, although particular attention is drawn
to the requirements of the latest 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 boiler in a room containing a bath or a
shower.
Where the installation of the boiler will be in an unusual position, special
procedures may be necessary and BS5376:2 and BS5546 give detailed
guidance on this aspect.
A cupboard or compartment used to enclose the boiler must be designed and
constructed specifically for this purpose. An existing cupboard or
compartment may be used provided that it is modified for the purpose.
Details of essential features of cupboard/compartment design including airing
cupboard installations are given in BS5376:2 and BS5546.
Boiler dimensions, minimum clearances and connection details are shown in
frames 1, 12 and18:
Fit one or more drain cocks to enable the water system to be fully drained.
Note: THE PUMP MUST BE WIRED BACK TO THE BOILER, see wiring
diagrams, frames 46 and 47. For low head system see frame45.

Heat inputs and outputs together with burner setting pressures are given in
