BOILER SITING AND BASE
The boiler should be sited in accordance with BS 6644:
1991 with respect to protecting the boiler from
damage, air for combustion and ventilation discharge
of products of combustion, clearances for service and
access, temperatures, noise levels, the disposal of
boiler water and the effects of flooding of the boiler
house or seepage from a roof top boiler house. See
section 1 for required boiler clearances for service and
access.
IMPORTANT: Boiler base must not protrude from rear
of boiler otherwise difficulty will occur in fitting 3"- 4"
extension turrets on rear return connections.
A level non-combustible floor capable of supporting the
weight of the boiler filled with water, see technical data,
together with any additional weight bearing down on
the base from connections, burner, etc, must be
provided. This will typically be a 50mm concrete plinth
with an area equal to that of the plan of the boiler.
Consideration should be given to fitting steel strips
beneath the boiler feet for boiler base protection, see
Fig.2 for base details.
The boiler has a water cooled base and no special
insulation is required.
reference should be made to Local Authorities and
Building Regulations 1992.
Before any work takes place Risk Assessments should
be carried out, to determine what possible risks are
associated with the work which is taking place.
L.P.G boilers should
basements/below ground or in a well.
It is not recommended to install commercial boilers in
kitchen or living areas.
For further advice on installations, refer to
