Page: 8 / 44

The oil supply connection between the storage tank and
the oil pipe should be run in copper or steel pipe with a
minimum diameter of 10mm. Galvanised pipes and
fittings should not be used. Annealed copper pipe is
preferred with flare type manipulative fittings. Capillary
fittings with soft solder should not be used. Steel pipes
should be joined using taper threads.
All pipe work and fittings must be completely air tight.
Only oil resistant compounds and PTFE tape should be
used when making joints. Pipe work must be protected
against damage whether fitted above or below ground.
The size and arrangement of pipe work will depend upon
the distance and height of the oil storage tank in relation
to the oil pump inlet.
The oil line from the storage tank to the appliance must be
fitted with a remote acting OFTEC approved fire valve
operating at 150°F, fitted with an appropriate length of
capillary to enable the valve body to be located externally
at the point where the oil line enters the building. The
sensing bulb of the fire valve MUST be fitted to the clips
located on the L.H. side of the appliance. See Fig. 5.
The 5-10 micron oil filter supplied with the appliance must
be fitted on the oil pipe line and stop valve must be fitted,
as close to the cooker as possible in an accessible
position.
A flexible pipe connection, approximately 1000mm long,
is supplied to fit between the oil supply pipe and the oil
pump for ease of burner removal. This must be contained
within the appliance case.
Where the oil pipe connection is taken at 90° from the
cooker a special elbow fitting is supplied loose with the
cooker.
The minimum recommended oil tank size is 1400 litres,
which must be installed in accordance with the relevant
regulations in force and the code of practice governing its
installation are covered by BS 5410 Part 1 Mild Steel
Tanks should be to BS 799 Part 5 and plastic tanks to
OFTEC standard OFS T100.
