4 INSTALLATION INSTRUCTIONS
The installation, commissioning and servicing of the boiler must be carried out by a
competent person who holds valid ACS certification and to be a member of CORGI.
All electrical work must be carried out by a competent person and to be installed in
accordance with the current IEE regulations.
4.1 General
Care should be taken when unpacking the boiler.
4.2 Boiler positioning
The boiler should be mounted in a room which, even during severe cold weather,
remains frost-free (see Par. 7.2.5 for more information). The boiler should be mounted
on a suitable vertical wall which is able to support the weight of the boiler.
If the boiler is to be installed in a timber framed building, please refer to British Gas
publication: ‘Guide for Gas Installations in Timber frame Housing’, reference DM2.

4.3 Boiler mounting
The boiler can be mounted in two ways:
1. using the wall bracket supplied with
the boiler,
2. using the mounting frame (optional)
supplied in a seperate box.
4.3.1 Clearance requirements
The gas and water connections are
located on the bottom of the boiler.
Whether the standard wall bracket or
the mounting frame is used, there is
adequate space to run the pipes behind
the boiler if required. All components are
accessible from the front of the boiler.
However, we do recommend a minimum
side clearance of 2.5 cm so that the unit
is easy to open. A free space of 25 cm
under the appliance and 40 cm above
the appliance, see Fig. 05, should be
regarded as the minimum requirement.
