6. FLUE SYSTEMS
5
Approved anti-downdraught
Min Height
This appliance is designed to operate with a Class 2 flue,
nominally 125mm (5") diameter. To ensure correct performance,
both flue and termination should conform to the relevant British
Standard.
NOTE: COMBUSTION TESTING, FLUE GAS ANALYSIS AND
DRAUGHT MEASUREMENT MUST BE CARRIED OUT ON SITE
BY THE APPROVED COMMISSIONING ENGINEER.
The quality of the flue is vital for satisfactory operation. A thorough
pre-installation check by a flue specialist is advisable. If an existing
flue is to be used, the specialist will advise on re-lining and the
correct choice of cowl or terminal for site wind conditions etc.
Before installing the appliance into an existing flue, check that:
the flue is clear of obstructions. Repair any structural damage.
•
the flue pipe is continuous. Any breaks in seals, flue liners etc.
•
must be rectified. A flexible steel liner (oil grade), BS4543 Parts
1 & 3 is highly recommended.
the flue diameter is uniform over its entire length.
•
the flue is not serving another appliance. Never connect to a
•
shared flue.
the flue is not constructed wholly of a single-skin pipe. This
•
must not be used under any circumstances. It has minimal heat

vermiculite backfill, or the equivalent, is used whenever a
•
lexible liner is installed. It must be sealed top and bottom.
f
salt-glazed clay or pre-cast liners are acceptable.
•
the most appropriate cowl depends entirely on conditions at
•
he site. Several may have to be tried before one is found that
t
gives good all-year performance. In some circumstances it
may not be possible to entirely exclude downdraughts
aused by surrounding buildings or trees, so fit an anti-
c
downdraught cowl, preferably of the O-H type.
A ‘Chinaman’s Hat’ is not sufficient.
7. FLUE HEIGHT
A minimum of 4 metres (15 feet) is required between cowl and
round level.This ensures that the flue gases are vented into
g
relatively non-turbulent air, and will be less affected by nearby
buildings or trees etc. In certain circumstances, trees or other
bstructions may need to be removed.
o
Installation with flues in excess of 10M in height is not
recommended. Very tall flues are likely to exceed the maximum
flue draught specified in the technical data. High flue draughts can
cause problems with oven and hob temperatures and increase
running costs.
The cowl must be at least 1 metre above any obstruction within
600mm, and the siting of the flue should comply with OFTEC
regulations.
8. HORIZONTAL RUNS
Horizontal runs of greater than 450mm (18") should be avoided.
If the flue has to be offset, the recommended angle is 60° and the
legal minimum 45°. Never use a bend of 90°.
If the installation is using an existing flue, horizontal runs should be
avoided. A vertical rise of 600mm is the mandatory minimum
before turning into the flue. If it is necessary to exhaust into an
extended flue after the mandatory 600mm rise, the horizontal run
must not exceed 450mm.
NOTE: ALL FLUE CONNECTIONS MUST BE FULLY SEALED
AND INSPECTED BY THE INSTALLER ON COMPLETION.
9. FLUE CLEANING
Annual inspection and cleaning of the flue is recommended.
Therefore a cleaning door, or some other means of access, should
be incorporated into the system.
10. HEARTH CONSTRUCTION
The cooker must be installed on a non-combustible surface
designed to take its weight. For example, concrete slabs or similar.
11. CLEARANCE TO COMBUSTIBLES
Allow 15mm to the rear of the unit for the circulation of air and
the escape of cooking vapours. Do not tile down as far as the top
plate surface – if the top plate has to be removed at some time in
the future, the tiles would be damaged.
Allow 20mm to either side. Vertical filler pieces can be used.

12. OIL TANK SUPPLY PIPING
The appliance must be supplied by an oil tank and pipework of an
OFTEC approved standard, and installed to current OFTEC Codes
f Practice. Mild steel tanks should conform to BS541, plastic
o
tanks to OFT100.
14. FLUE DRAUGHT INTERFERENCE
ppliances with the ability to extract air should not be located in
A
the same room as the oil-fired Range Cooker. If this proves to be
impracticable, then additional air inlets to should be provided to
ompensate. A Flue Draught Interference Test will determine
c
whether or not there is an adequate air supply.

GENERAL FAULT FINDING CHART FOR SINGLE, COMBINATION AND
DOUBLE OIL BURNERS
5
A = 450mm minimum height above the Cooker Oil Control Valve
H = Head of oil not more than 3m above the Cooker Oil Control Valve
It is important that the oil supply pipe and the height of the tank
are sufficient to enable 0.8 litres of oil per hour to pass freely into
the burner. Calculate the size taking into account the total friction
losses in the pipe, including bends etc.
Run the oil supply pipe to the rear LH side of the cooker, where it
will join with the Preformed 8mm Feed Pipe, which connects to
the Oil Valve. Easy access is gained to this pipe via a magnetic
access panel.
NOTE: A FUEL SHUT-OFF VALVE MUST BE FITTED AS CLOSE
TO THE APPLIANCE AS POSSIBLE – AND BE ACCESSIBLE AT
ALL TIMES. IT SHOULD BE CLOSED WHEN THE PROPERTY IS
VACANT FOR ANY LENGTH OF TIME.
Oil tank and pipe installation
13. AIR SUPPLY
Whenever a flued appliance is installed, a permanent air vent
must be provided. It must be located to take its air either from an
external source, or from an adjacent room which itself must have
a permanent external air vent of at least the same size.
For oil fired appliances, British Standard Code of Practice BS
5410: Part 1: 1997 requires that combustion air must be provided
into the room containing the appliance through purpose made
non-closable openings, having a total free area of 550mm
of the appliance maximum output rating above 5 kW.
This requirement does not apply if a room sealed balanced flue
appliance is used.
The Building Regulation for England, Wales, Scotland require that
an air supply to each appliance is provided, in accordance with
the requirement of BS 5410: Part 1: 1997. In the Republic of
Ireland, the Regulations advise that an air supply of 550mm
each kW of appliance output above 5 kW is provided.
This appliance requires a minimum of 755m2.

F
When the extractor is in the same room as the appliance – all
doors, windows and additional ventilation openings to the room
ust first be closed.
m
When the extractor is elsewhere in the building – all doors,
windows and additional ventilation openings must be closed, and
internal doors left open. The extractor should then be run at
maximum speed. As soon as the normal airflow pattern has been
established, the appliance should be set to maximum.
Combustion condition readings should then be taken with and
without the extractor fan running. The appliance should work
satisfactorily in either case. If not, additional ventilation must be
provided.
VENTILATION RESTRICTIONS
Where the appliance has a Vaporising Burner, the mechanical
extract rate from the area in which it is installed must not exceed
20 litres per second.
In the case of a Pressure Jet Burner, the rate must not exceed 40
litres per second.
OTHER INTERFERENCE WITH AIR SUPPLY
Other appliances like tumble driers, which discharge air to the
outside, have the same effect as extractor fans.
Other heating appliances in the same area using different fuels can
also have an adverse effect. They must have their own air supply
complying with Building Regulations for that particular fuel.
15. BURNER INSTALLATION

Burner Assembly
When the appliance is in its final position and has been levelled,
connect the 10mm Oil Feed Pipe to the KBB Remote Acting Fire
Valve, 8mm connection to the Preformed Feed Pipe on the LH
side of the cooker, and then to the inlet of the Oil Control Valve.
Purge the Oil Feed Pipe to remove air locks, then open all valves
to allow oil into the Oil Control Valve.

Withdrawal of the assembly
Check that the oil supply has been isolated, then disconnect the
Oil Supply Pipe from the Oil Control Valve, avoiding spillage.
Remove the Burner Assembly by undoing the two nuts securing it
to the Combustion Chamber and lifting it out.
In exceptional cases, it may be necessary to remove the Oil
Control Valve metering stem. This must be done with great care,
avoiding any damage to the slot – which must be cleaned with a
wooden cocktail stick, or similar. Never use anything metallic, as it
could increase the slot width and seriously affect flow rates.

SERVICING INSTRUCTIONS
IMPORTANT
It is essential that range cookers are serviced, and flue ways inspected and cleaned, at regular 6-monthly intervals. The frequency
ay be increased if a lower quality fuel is used. The work must be carried out by Don/Oftec trained service engineers.
m
The appliance should be turned off at least 4 hours before the arrival of the engineer, to allow it to cool.
NOTE: BEFORE STARTING WORK, MAKE SURE THAT BOTH
IL AND ELECTRICAL SUPPLIES HAVE BEEN ISOLATED.

Leave the Oil Control Knob at ‘High +’, and turn the Thermostat
to its mid position. Shut the Burner Door, and leave for 20
minutes until the burner is hot, then reset the Thermostat to its
maximum ‘Hot +’ position.
The Burner will gradually increase its oil flow rate and raise the
temperature of the oven, taking about two and a half hours to
reach 200˚C (400˚F). Turn the Thermostat to the mid position,
and the oven will maintain its temperature. When cooking is not
required, the Thermostat can be turned to its minimum
‘Warm –‘ setting.
When the appliance is first fired, it may give off a slight odour for
a short time. This is normal, and no cause for concern.
Remove the Boiling and Simmering Hotplates. First release the 3
screws on each hotplate, and wind the plate out to expose
approximately 30mm. Attach the spider tool provided by locating
it under the 3 countersunk screw heads, then rotate the plate
anti-clockwise and lift it clear of the cooker. The Boiling Plate is
much heavier, so take care as you remove it.

21. TESTING BURNER
SMOKE
Using the Sampling Hole in the front of the Flue Hood Assembly,
sample the flue products with a Baccarach Smoke Pump and
check the flue draught. Adjust the draught divertor to give the
required flue draught. See Technical Specification on page 2.
All readings should give a Smoke Number of 0-1 at both low rate
and high rate.
