28 Connecting the Oil Supply
5.1 Essential Elements in the Oil Supply
This appliance is suitable for Kerosene (Class C2) and Light-oil.
No other fuel may be used.
Fuel Storage Tank
The tank should be positioned in accordance with the
recommendations given in BS 5410:1:1997, which gives details
for filling, maintenance and protection from fire.
A steel tank may be used and must be constructed to BS
799:5:1987 and OFS T200.
CAUTION
Ɣ
A galvanised tank must not be used.
Ɣ
A plastic tank may be used and must comply with OFS
T100.
Note
Plastic tanks should be adequately and uniformly
supported on a smooth level surface, across their
entire base area, that is, the area in contact with the
ground.
Regulations & Standards
In England and Wales, installations in singe family dwellings
have to comply with building Regulations Part J. This requires
compliance with BS 5410 Part 1:2014. All tanks either deemed to
be at risk or with a capacity of more than 2500 litres are required
to be bunded.
For installation in Scotland, Building Standard Part F applies. This
requires compliance with BS 5410 Part 1:2014 and BS 5410 Part
2:2013. All tanks either deemed to be at risk or with a capacity of
more than 2500 litres are required to be bunded.
Those externally installed tanks with a capacity of less than 2500
litres will require a bund if located not more than 50 metres from
a spring or bore hole, 10 metres from controlled waters and,
additionally, where it may constitute a hazard.
The above risks and hazards are described in OFTEC book 3.
In Northern Ireland, the Building Regulations do not currently
cover the installation of oil storage tanks.
In the Republic of Ireland the requirements of BS 5410 Part
1:2014 and BS 5410 Part 2:2013 are required to be in compliance
with Building Regulations Part J.
Fuel Pipes
Fuel supply pipes should be of copper tubing with an external
diameter of at least 10 mm.
Galvanised pipes may not be used.
All pipe connections should preferably use flared fittings.
Soldered connections must not be used on oil pipes.
CAUTION
Flexible hoses must not be used outside the boiler.
Fire Valve
A fire valve is an essential part of the oil supply system. It should
be capable of cutting off the flow of oil outside the building in
the event of a fire starting within the boiler. The valve should
be located just outside the building at the point where the
oil supply line enters. It must be activated by a remote sensor
located over the burner, but in a position clear of any direct
radiation or excessive heat.
Note Ɣ
Fire valves should comply with OFTEC Standards
OFS E101.
Ɣ
Fitting of fire valves should comply with BS5410
Part 1:2014 and OFTEC book 3.
Oil Strainer & Water Separator
Fit an oil strainer and water separator to the oil supply pipe, near
the oil storage tank.
Fit an additional oil filter (74μm max filtration size) close to the
boiler, but not inside the boiler.
Install a manual shut-off valve. It should be fitted before
installing the filter, to allow the filter to be serviced. Install the
valve as close to the oil storage tank as possible.
CAUTION
Contaminants can lead to system damage. The oil line must
be flushed prior to commissioning.
