Installation
Before starting work a risk assessment should be
carried out in the boiler house and its access to
determine and ensure a safe installation and working
environment.
Any person installing or working on the boiler must
be qualified and competent, and in the case of gas
fired boilers attention is drawn to the mandatory
requirement of CORGI. Registration and qualified to
ACOP's Element 16. They must also be electrically
competent and adhere to the IEE regulations.
Manual Handling – Any person or persons moving or
lifting the boiler or any part of it, should be trained in
manual handling techniques and if necessary use
suitable lifting equipment to reduce the risk of injury
to themselves or other people.
The installation should comply with relevant British
Standard Specifications, Codes of Practice and
current Building Regulations, together with any
special regional requirements

Boiler Siting and Base
The boiler should be sited in accordance with
BS 6644 - 1991. This includes considerations for
protecting the boiler
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 boilerhouse. See Fig. 2
for required boiler clearances for service and access.
A level non-combustible floor capable of supporting
the weight of the boiler filled with water, see Table 3,
together with any additional weight bearing down on
the base from connections, burner, etc, must be
provided. This should be of an adequate height
above the floor so as to be raised in case of flooding,
but also low enough to allow ease of erection.
Typically a 50mm concrete plinth with an area equal
to that of the plan of the boiler.
For certain special installations a sound proof plinth
may be necessary and a metal plinth resting on anti-
vibration pads is recommended in these instances.
Consideration should also be given to fitting steel
strips beneath the boiler feet for boiler base
protection, see Fig. 3 for base details
The boiler has a water-cooled base and no special
insulation is required. When preparing a site,
reference should be made to Local Authorities and
Building Regulations 1991.
LPG boilers should
basements/below ground or in a well.
