3.3 Boiler
Location
The boiler location must permit the provision of a
satisfactory flue system, and provide adequate
space around the boiler for servicing and air
circulation.
Sufficient space must be provided at the front of the
boiler to allow the removal of the burner assembly
for servicing/replacement, and at the rear for
installation of pipes, valves and flue.
Sufficient clearance above the boiler must also be
provided to allow access for servicing. Refer to
Section 2.2 for recommended clearances.
The boiler room, or compartment, housing the boiler
(s) - whether specifically constructed for the
purpose, or a modification of an existing space -
should be in accordance with the requirements of
either BS.6644, BS.5410 Part 1, or BS.5410 Part 2,
as appropriate.
Where a separate purpose built boiler room is not
available, measures should be taken to protect the
boiler or boilers from damage, and the boiler should
be sited such that extraneous material cannot be
stored next to, or against it.
The boiler should be installed on a non-combustible,
level plinth of 50mm nominal height, capable of
withstanding temperatures of 65 deg. C, and able to
support the weight of the boiler (including pipework
and ancillary equipment) when filled with water.
The plinth should end flush with the boiler casing
front to prevent interference with the burner oil
pipework or gas train and should be at least the
width and length of the casing dimensions.
The compartment housing the boiler must have
permanent air vents communicating directly with the
outside air at both high and low level. Refer to
Section 3.7 for details.
3.4 Gas
Supply
The Gas Safety (Installation and Use) Regulations
require that only competent persons, i.e. CORGI
Registered gas installers, should install gas
