FUEL INSTALLATION
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 one can be
vented off. It is important to avoid high points which
could cause air locks.
Exposed lengths of oil supply pipe must be 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 protected
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 stop valve must be
fitted to the fuel feed line and located near the
supply tank and facilities should be provided to
enable it to be serviced without draining down the oil
supply system. (See Figs, 32, 33, 34 & 35).
At the point where the oil line enters the building, the
oil line must be fitted with an approved remote
acting fire valve, which meets the requirements of
B.S. 5410 : Part 1, fitted with the appropriate length
of capillary. The heat sensoring phial of the fire
valve must be fitted to the clip provided in the burner
compartment. 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 are 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.
When gravity feed is used (the most common) the
minimum head should not be below 1 meter (3’3”)
and the maximum head should not exceed 6.5
meters (21’ 3”).
NOTE:
The pump is factory set for a single pipe
installation to convert to a two pipe system consult
manufacturers instructions.
Before connecting the oil supply, secure appliance
burner oil pipes to the base using the T junction (see
Fig. 30 & 31).
OIL STORAGE TANKS
Oil storage tanks made of steel and all connecting
equipment (eg: 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
translucent plastic containers.
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. 32, 33, 34 & 35).
In order to enable the sediment and water to be
removed from tanks a drain valve should be fitted.
Oil storage tank support must be carried out in
accordance
with
the
tank
manufactures
recommendations. Tanks should be located in the
most unobstructive position possible having taken
safety, filling, maintenance and the need, if any, to
provide a head of oil for the burner into
consideration.
FUELS
THE RECOMMENDED FUEL IS KEROSENE 28
SECOND VISCOSITY FUEL OIL.
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 9mm (3/8”)
and connected to the oil inlet connection located at
the cooker left hand side.
Oil supply pipes are normally run in annealed
copper tube complying to B.S. E.N. 1057. It can be
obtained in coil or half hard form for use with
bending machines. This pipe can also be obtained
with protective plastic sheathing applied. Fittings
for copper pipe should be compression of the flared
manipulative type to B.S. 864: Part 2 1983. Steel
pipes complying 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 tapered
threads complying to B.S. 1740: Part 1: 1971.
