The boiler should be mounted on a flat and vertical area
of wall of sufficient area for the boiler plus the required
clearances for installation and servicing (fig. 3.8). These
are shown on the installation template supplied with the
boiler and are:
– 5 mm either side of the boiler
– 145 mm below the boiler
– 205 mm* above the boiler when utilising the 100 mm
outside diameter flue
– 220 mm* above the boiler when utilising the 125 mm
outside diameter flue
– 500 mm in front of the boiler**
Note!
If the boiler is to be fitted in a timber framed
building, it should be fitted in accordance with
British Gas publication DM2 ‘Guide for gas
installations in timber framed housing’.

Refer to section ‘Boiler location’ for information
regarding siting the appliance. In general the boiler must
be positioned such that:
• There is adequate space around the boiler for service
and maintenance

position is sited in accordance with these instructions
and the air/flue duct can be installed in accordance
with the flue installation instructions supplied.
• All necessary pipework can be connected, including
the pressure relief valve and condensate drain.
** This clearance is only required to enable easier access to the boiler for
servicing and may be provided by an openable door, etc.
