SEE FIG. 2
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 airtight. 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 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 fire valve
operating at 140ºF (65ºC), 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 heat sensing phial of the fire valve
MUST be fitted in an appropriate position to protect
the building.
The paper element oil filter supplied with the appliance
must be fitted on the oil pipe line and isolation valve must
be fitted, as close to the cooker as possible in an
accessible position. A fire valve must be installed to
protect the property and the phial fitted in the clips
provided.
Aflexible pipe connection, is supplied to fit between the oil
supply pipe and the oil pump for ease of burner removal.
When positioning the tank, due consideration should be
given to appropriate access for fuel delivery vehicles.
Positioning should comply with the relevant standards.
The tank should be complete with the following:
1. Sludge cock (steel tanks)
2. Outlet valve and filter
3. Contents indicator
4. Vent pipe
To prevent entry of water or fitted with return bend.
5. Fill pipe and screw cap (50mm black pipe)
The use of open lids to fill tanks is not recommended.
Steel Tanks - should be mounted on suitable supports. If
of masonry, a damp proof membrane should be
positioned between the tank and its supports to prevent
the steel from rusting when in direct contact with water.
Steel tanks should slope 20mm for each 1m run from the
oil outlet towards the sludge cock (opposite end).
Plastic Oil Tanks - UV Stabilized, plastic tanks are a
modern alternative to steel. These green tanks are
protected against sunlight and do not need to stand on
piers. They do however need to be supported over their
entire base area. Ideally 50mm smooth faced garden
slabs bedded down onto sand or a smooth concrete base.
The single tapped outlet makes them more suited to
single pipe gravity feed.

The flue system must be installed to the regulations in
force.
Information
Mean flue gas temperature 260ºC.
The appliance requires a minimum negative chimney
draught of 1.0mm W.G. (0.04” WG) with the burner on.
Maximum chimney draught 3.7mm (0.15” WG). Draughts
in excess of this will require a draught stabilizer fitted
either in the chimney or flue pipe and in the same
compartment.
Due to the range in flue gas temperature a brick chimney
should be fitted with a suitable multi fuel stainless steel
flexible liner. Factory built chimneys must comply with the
relevant standards.
The cross-sectional area of the flue serving the appliance
must not be less than the equivalent area of 100mm
diameter flue pipe, and be at least 4.5m high.
The flue pipe must not be less than 100mm internal
diameter. Flue pipes and fittings between the appliance
and the chimney should be constructed from one of the
following materials:
a. Cast Iron
b. Mild steel, acid resistant vitreous lined
Chimney Terminations
All chimneys should terminate above roof level, or with
the relevant standards in force.
Chimney Cleaning
Ensure there are accessible airtight flue cleaning doors in
order to obtain access to the complete chimney . Providing
the appliance is operating correctly, an annual chimney
flue cleaning will suffice, but if in doubt arrange for a half
yearly clean.

The appliance can only be installed in a room which
meets the ventilation regulations in force. But, in any
event the room must have a permanent vent of minimum
free air area, see below.
Detailed recommendations are given in the relevant
standards and codes of practice. The following notes are
intended for general guidance.
1. Combustion and ventilation air supply to oil fired
appliances has to comply with the relevant standards
and codes of practice. The air supply requirement for
oil fired appliances is 550m
2
per kW of maximum rated
output above 5.0 kW.
2. The combustion air supply to open flued appliances
should normally be provided at high level into a room
where it will not cause discomfort by creating a cold
draught across the floor.
3. If combustion air is supplied through an under floor
duct the grilles at each end should be positioned in the
vertical plane to reduce risk of blockage. Ducts should
be sized so as to reduce resistance air flow.
4. Extract fan should be positioned as far away from the
open flue as possible and should have a sufficient
dedicated air supply. To undertake a test the oil fired
appliance, should be set in operation and the doors
and windows of the room containing it should be
closed. The extract fan should then be run at its
maximum setting. The oil fired appliance should then
be run at its maximum setting. The oil fired appliance
should be observed to operate satisfactorily both
before and after the fan is switched on.
5. It is preferable for the air supply for an extract fan to be
located where it can serve the fan without the air
stream passing close to the oil fired appliance.
6. Oil fired appliances must not draw combustion air
from a garage.
Wiring external to the appliance must be installed in
accordance with the relevant standards, wiring
regulations and any local regulations which apply. The
appliance is supplied for 220/230 Volt - 50 Hz and a fuse
wiring of 3 amps.
The method of connection to the mains supply should
facilitate complete electrical isolation of the appliance, by
the use of a fused double pole switch having a contact
separation of at least 3mm serving only the appliance.
The point of connection to the mains should be readily
accessible and adjacent to the appliance. The installation
should be protected by a 30mA Residual Current Circuit
Breaker (RCCB).
The minimum requirement for the power cable is that it
should be a 3 core PVC sheathed flexible cord (85ºC min)
at least 0.75mm
2
(24 x 0.2mm) to the relevant standard.
WARNING: THIS APPLIANCE MUST BE EARTHED.
In the event of an electrical fault after installation of the
appliance, preliminary electrical system checks must be
carried out i.e. earth continuity, short circuit, polarity and
resistance to earth.
For wiring instructions, see wiring diagram.

Remove the bleed screw from the manifold and fit an oil
pressure gauge with R 1/8 connection to check the pump
output pressure.
Switch on the Electricity
Set the cooker oven thermostat to position 4, wait 2
minutes for the pre-heater. The burner should run on prepurge for 10 to 20 seconds, with the ignition spark
energised. The oil solenoid valve should then open
allowing the burner to fire.
Until all the air from the oil pump is flushed out there may
be some flame instability resulting in the burner locking
out.
This will be shown by the burner stopping and the
illumination of the signal light in the reset button of the
control box (See Fig. 10). In this event, wait at least one
minute, then press the reset button to restart.
NOTE: This appliance is fitted with a pulse burner which
has a four minute on and four minute off cycle.
SEE FIG. 9
Whilst the burner is running, vent air from the pump by
slackening the pressure gauge connection sufficient to
allow air to bleed out. When bubble free oil seeps out
retighten.
SEE FIG. 9
After 15 minutes:
Whilst the burner is running, check the oil pressure on the
gauge. Wait for 30 seconds after ignition, for the burner to
establish the full firing rate.
If the pressure gauge is not indicating the correct reading
then adjust the pressure by turning the pressure regulator
clockwise to increase or anti-clockwise to decrease the
pressure until the pressure gauge reads 5.2 bar (80
Ibf/in
