FUEL SUPPLY / INSTALLATION
OIL STORAGE TANKS:
Oil storage tanks made of steel and all connecting
equipment (e.g. filling pipes, and vent pipes) should
comply with B.S. 799 Part 5. Galvanised steel must
not be used. Polyethylene (Plastic) tanks should
comply with OFTEC standard OFS T100 and or
equivalent. Oil should never be stored in transulent
plastic containers.
In order to enable sediment and water to be
removed from steel tanks a drain valve must be fit-
ted.
An isolating valve should be fitted at the tank outlet,
in an accessible position so that the oil supply to the
appliance can be shut off if required. This isolating
valve must be of a type suitable for use with oil. (see
Fig.2)
Oil storage tank support must be carried out in
accordance with the tank manufacturers recommen-
dations. Tanks should be located in the most un-
obstructive position possible having taken safety, fill-
ing, maintenance and the need, to provide a head of
oil for the burner into consideration.

FUEL SUPPLY LINE
The oil supply line from the oil storage tank to the
appliance should be of an approved and suitable
pipe with a minimum internal diameter of 8mm
(5/16") and connected to the oil control valve.
Oil supply pipes are normally run in annealed cop-
per tube complying to EN 1057, it can be obtained in
coil or half hard form for use with bending machines.
This pipe can also be obtained with protective plas-
tic sheathing applied.
should be compression of the flared manipulative
type to B.S. 864: Part 2 1983. Steel pipes comply-
ing with B.S. 1387: 1985, if used, must be protected
from corrosion. Galvanised pipe and fittings must
not be used.
Screwed joints must only be made with taper
threads complying to B.S. 1740 : Part 1 1971.
Jointing materials must be of types intended for use
with oil fuel. Special petroleum resisting compounds
and PTFE tape are suitable. External pipes should
preferably be run with a continuous rise towards the
direction of flow, so that air can be vented off. It is
important to avoid high points which could cause air
locks. Exposed lengths of oil supply pipe must be
Fittings for copper pipe
properly supported by purpose made clips securely
fixed in place. Metal clips formed so as to hold the
pipe on to a saddle are preferred. Consideration
should be given to avoiding routes which expose the
pipe to severe chilling which could cause freezing of
the oil. Where pipes are buried, they must be pro-
tected from accidental damage. The use of joints
underground should be avoided if at all possible. If
joints have to be fitted in pipes laid below ground,
access to them must be provided.
An oil filter (5 - 10 micron) and a stop valve must be
fitted to the fuel feed line and located near the sup-
ply tank and facilities should be provided to enable it
to be serviced without draining down the oil supply
system. (See Fig. 2).
At the point where the oil line enters the building, the
oil line must be fitted with an approved remote act-
ing fire valve which meets the requirements of B.S.
5410 : Part 1, fitted with the appropriate length of
capillary. The temperature rating limit should be

C. The heat sensoring phial of the fire valve
must be fitted to the clip provided at the back of the
stove. It is absolutely essential that the fire valve is
located externally and is as close as possible to the
appliance. For existing installations where the oil
supply is built into the structure internally, the remote
acting fire valve should be fitted where the oil supply
line is first exposed internally. This type of layout is
not recommended for new installations.
