Installation requirements
Boiler location (Refer Figs 2 & 3)
The location chosen for the boiler(s) must be frost free,
provide for a satisfactory flue system and an adequate air
supply for combustion and ventilation. Adequate access is
necessary for boiler and burner servicing.
Boilers must not be installed in areas where flammable
vapours are likely to be present. To avoid damage to the
boilers, contamination of the combustion air by high levels
of dust or halogenated hydrocarbons (eg. Solvents, spray
can propellants, cleaning agents, adhesives, etc) must be
avoided.
Boilers should be installed on a plinth which is at least
50mm high and is smooth and level (NB : for some burners
with acoustic shrouds the plinth may need to be higher -
refer Sales Office).
An uneven plinth can inhibit freedom for expansion and
contraction of the boiler during operation.
Burners
Boilers can be supplied with one or two stage Natural gas,
LPG, Class D or Class C oil burners. A choice of burner
makes is available.

Plant room layout (Refer Fig 2)
When planning the layout of the boiler room, allowance
must be made for opening the boiler door, boiler
assembling, boiler cleaning and maintenance. The boiler
door may be hinged from the right (as illustrated) or the left.
A ceiling height of at least 2.3m is recommended. Wall
clearances are:
W1 - at least 700mm.
W2 - burner length A + 100mm.
W3 - 1000mm (in front of boiler for cleaning).
W4 - 500mm minimum (behind boiler for cleaning).
Plinth dimensions (Refer Fig 3)
Plinth height - at least 50mm, smooth and level.

Fuel specification
Natural gas (GCV 38.76 MJ/m
3
) with a minimum gas inlet
pressure according to the burner model specified.
BS2869 Class D oil (35 sec). Advice should be sought
from the oil supplier regarding the storage of Class D oil.
Fuel supply pipework
Install gas or oil supply pipe(s) and service valve(s) so as
to allow free access to the boiler and full opening of the
furnace door without removing the burner from the boiler
door (see below).
Commissioning of the gas supply pipework and
components must be carried out by a qualified person, eg,
a Gas Safe registered engineer. The gas meter and
supply must be sited in accordance with the requirements
of BS6400.
