8. OIL SUPPLY
OIL
8.1 The oil burner is factory set to burn CLASS C2 kerosene to
BS2869.
OIL STORAGE TANKS
8.2 Size and Location of Tank in accordance with OFTEC
regulations.
The tank should be large enough to allow for economic
deliveries and be located in the most unobtrusive position,
having regard to the need for safety, filling, maintenance (if
steel tank) and head of oil required.
8.3 Whist it is highly unlikely that a fire could start from an oil
tank, it does need to be protected from a fire that may
originate in a nearby building. For this reason, the tank
should not be located nearer than 1.8 metres from a
building, nor closer than 760mm from a site boundary.
Where a tank has to be less than 1.8 metres, the building
wall must not have any openings other than small ventilation
openings. The wall shall have a 30 minute resistance to an
internal fire and extend 1.8 metres from any part of the
tank.
8.4 Alternatively, a non-combustible radiation barrier must be
provided which meets the requirements of BS5410. This
standard applies to tanks up to a capacity of 3,400 litres.
FIRE PROTECTION – PART J
8.5 Where a storage tank is close to a dwelling, fire cladding
must be provided to the eaves if less than 1.8m from the
top of the tank
8.6 The cladding must extend 300mm beyond the tank
8.7 The tank must be sited on a non-combustible base.
J6 – PROTECTION AGAINST POLLUTION
A tank must be bunded if:-
– Less than 10 metres from “controlled water” such as a
stream, ditch, river, lake, pond, canal or coastal water.
– Less than 50 metres from a well, spring or drinking water.
– The tank cannot be viewed from the delivery point.
– There is a risk of oil reaching a manhole cover or drain.
– If the capacity exceeds 2500 litres.
– Sited over hard ground or hard surfaced ground that could
allow spilled oil to enter “controlled water”.
STEEL TANKS
8.8 Steel tanks should comply with the requirements of BS799,
Pt 5, 1987 and mounted on brick or block piers with a
waterproof membrane between the piers and tank.
8.9 The tank should be fitted with fill and vent connections
(weather protected), a drain-off cock, shut-off valve and an
oil level indicator.
PLASTIC TANKS
8.10 Polythene tanks are now widely used because of their
advantages over traditional steel tanks:
– They do not need pier supports and can be mounted
directly on any flat surface giving uniform support for the
tank base.
– They do not corrode and therefore never need painting.
– They are easier to handle because of their lower weight.
– They have a 10 year manufacturer’s guarantee.
Plastic tanks should be fitted with similar components to
those used with steel tanks.
OIL SUPPLY LINE (see diagram 5)
8.11 A maximum head of 3.2 metres should be exceeded –
35kpa pressure. The oil shut-off valve should be fitted as
close to the burner as practical to enable the burner to be
disconnected without undue loss of oil. A 5-10 micron oil
filter must be fitted (preferably close to the tank in an
accessible position). The filter must be connected in the oil
supply pipe and positioned externally.
8.12 All oil line joints must be completely sealed and the total
pipe run thoroughly flushed out before connecting to the
burner. No soldered joints are permitted in the oil line.
FIRE VALVE
8.13 A remote acting 60°C fire valve must be fitted in the oil line
outside the building with its sensing phial positioned
adjacent to the oil control valve.
8.14 An additional 90°C fire valve must be fitted near to the
cooker on the incoming oil line with its sensing phial
positioned within the cooker. Clips are provided for
retaining the phial.
