LOCATION
When choosing a location for this appliance you
must have:
(a) Sufficient room for the installation (see clear-
ances), a satisfactory flue (see flue system),
and an adequate air supply for correct combus-
tion and operation (see Ventilation and
Combustion air supply).
(b) Adequate space for maintenance and air circu-
lation.
(c) Solid floor or base of non-combustible material
which is capable of supporting the total weight.
(see Technical Data).
HEARTH CONSTRUCTION
When a non-combustible floor surface is not avail-
able then we recommend that the cooker be placed
on a slab of pre-cast concrete 40mm (11/2”) deep or
a slab of other insulating material. This hearth must
extend 150mm (6”) to either side of the appliance
and 225mm (9”) to the front.
ELECTRICAL SUPPLY
All wiring external to the appliance must conform to
the current BS 7671, B.S. 7462, Safety Document
635 ETC: Part 1 Section 5.4.6. & the Electricity at
Work Regulations. The cooker requires a 230V -
240V, 50Hz supply. Connection of this appliance to
the mains supply must be through a moulded on
plug top (with a 3A fuse) which is fitted to the appli-
ance in accordance with EN 60335, Consumer
Protection: SI 1994 No. 1768, (plug and sockets
etc.) Safety Regulations 1994.
WARNING: THIS SUPPLY AND COOKER MUST
BE EARTHED (Refer to B.S. 7430 : Code for
Protection of Earthing).
Where there is a risk that the supply voltage could
fall below 190 volts, a voltage sensitive device
should be fitted to prevent the appliance from oper-
ating when the voltage is below 190 volts, so as not
to endanger the installation. Primary fuse is locat-
ed at rear of control box.
To isolate the appliance completely unplug from the
mains socket. Always ensure that this socket is eas-
ily accessible and close to the appliance. Persons
in charge of this appliance should be aware of this
socket outlet position.

REDUCED CLEARANCES
Where the flue passes through a combustible mate-
rial a twin wall solid packed insulated chimney con-
nector must be used and must come flush with the
outer surface of the material and run all the way to
the masonry chimney or to the point of termination
of the factory made chimney. (see Fig. 6)

FLUES
The chimney and flue pipes intended for use with
this appliance should be mechanically robust, resist-
ant to internal and external corrosion, non-com-
bustible, and durable under the conditions to which
they are likely to be subjected.
Flues require a suitable external terminal which
should be designed to permit the easy exit of com-
bustion products whilst providing protection against
the ingress of rain, birds and other foreign matter
into the system. Flue pipes and accessories such
as clips and stays should not be made of unprotect-
ed mild steel or other material which is likely to cor-
rode.
Where flue piping passes through a closure plate
with a sliding door, ensure that the pipe continues
up and is ultimately connected to the flue liner and
well sealed with fire cement.
Do not connect to a chimney serving another appli-
ance. Chimneys wholly constructed of single skin
pipe are not recommended under any circum-
stances. Due to their inability to retain heat such
chimneys will inevitably give rise to the formation of
condensation.
The outlet on the appliance is 6” (150mm) diameter.
The proudct is supplied with a reducer to reduce the
diameter of the chimney/flue form 6” (150mm) to the
required 5” (125mm). If using enamelled pipes or
bends it is permitted to use 6” (150mm) diameter up
to a length of 6ft (1.8 meter) from the outlet of the
Fig. 10
PRE-INSTALLATION CHECK
Before installing your cooker, check that the chim-
ney is clean and clear of obstructions. Cracked
brickwork and leaking joints should be made good.
IT IS RECOMMENDED TO CONNECT TO A FLUE
OR FLUE LINER OF 125MM (5”).
Flue Liner

SEALING
This cooker and flue system operate under a posi-
tive pressure, it is essential that all flue joints are
tightly sealed against flue gas leakage and tested
accordingly (see Fig. 11 & 12).
There is a flue pipe collar available which surrounds
the flue pipe where it meets the wall, giving a tidier
finish to a tiled background (see fig. 9). The flue
pipe collar is available as an optional extra, to order.
Refer to Flue Assembly Instructions sheets.
FLUE HEIGHT
The flue must be high enough 4.5 mts. (15ft) mini-
mum measured vertically from the appliance outlet
to the top of the flue terminal, to allow the flue gases
to vent into the clear air, away from the turbulence
that may be caused by roof structures, other chim-
ney stacks, etc. The terminal position should be in
accordance with B.S. 5410 and the current Building
Regulations.
If it is necessary to offset the chimney the recom-
mended angle is 60° to the horizontal and the statu-
tory minimum is 45° (see fig. 14).
Note: Never connect to a chimney or flue system
serving another appliance.
Fig.14
CONNECTIONS
A cast iron 90° bend with cleaning door is supplied
with the cooker, along with a cast iron spigot for con-
nection to a vertical flue pipe. A vertical cast iron
outlet pipe with cleaning door is available to order. A
flexible flue adaptor is supplied, this is to connect
the cooker bend or straight pipe to the chimney
liner.
Note: Maximum horizontal length should not be
more than 300mm (12”) where the appliance spigot
or flue pipe protrudes into the chimney, care should
be taken to ensure that it does not block the chim-
ney.
ALL FLUE CONNECTIONS MUST BE THOR-
OUGHLY SEALED.

Blocked chimneys are dangerous, keep chimneys
and flueways clean, read the operating instructions.
STANLEY CAST IRON PIPES AND BENDS ARE
HIGHLY RECOMMENDED FOR INTERIOR USE.
SUITABLE MATERIALS
* Mineral Fibre cement pipes conforming to
B.S. 7435.
* Sheet metal conforming to B.S.4076.
* Insulated metal chimneys conforming to
B.S.4543 and B.S. 5410 (a galvanised
finish is not suitable).
* Clay flue linings conforming to B.S. 1181.
* Pre-cast concrete chimney blocks,
incorporated into the building structure. It
is particularly important that the correct
connection block be provided at the base of
the flue, B.S. 3572.
* Cast Iron or acid resistant vitreous enamel
lined mild steel to B.S. 41.
FLUE CLEANING
The flue pipe must be fitted with a cleaning plate.
The flue must be inspected annually and cleaned
when necessary.
USE OF EXISTING FLUES AND CHIMNEYS
When connecting to an existing chimney it is neces-
sary to line the flue using approved 125mm (5”) rigid
or flexible stainless steel flue liner.
An existing flue pipe or chimney that has proved to
be satisfactory when used for solid fuel can normal-
ly be used for this appliance provided that its con-
struction, condition and dimensions are acceptable.
Flues that have proved to be unsatisfactory, particu-
larly with regard to down draught, must not be con-
sidered for this appliance until they have been
examined and any faults corrected. If there is any
doubt about an existing chimney, a smoke test to
B.S. 5410 should be carried out.
Before connecting this appliance to a chimney or
flue pipe which has previously been used with
another fuel, the chimney or flue pipe must be thor-
oughly swept and lined accordingly.
All register plates, restrictor plates, damper etc.
which could obstruct the flue at a future date must
be removed before connecting this appliance.
Where a chimney is not to be lined a suitable void
should be provided at the base to contain any debris
which might fall from inside the chimney, so as to
prevent that debris from obstructing the appliance
flue outlet. (Removal of debris should be facilitated
by the provision of an access door). The void
should have a depth of not less than 250mm (10”)
below the appliance connection.
The combustion products will have a descaling
effect on hardened soot deposits left from burning
solid fuels.
ALTHOUGH THE CHIMNEY MAY HAVE BEEN
CLEANED OF LOOSE SOOT PRIOR TO INSTAL-
LATION, IT IS IMPERATIVE THAT THE CHIMNEY
IS INSPECTED FOR SCALED SOOT PARTICLES
AFTER THE FIRST MONTH OF OPERATION AND
ANY LOOSE MATERIALS REMOVED TO AVOID
BLOCKAGE.
DRAUGHT REQUIREMENTS
While inadequate draught can seriously effect the
efficient operation of the appliance, chimneys over
(5.4m) 18ft. or houses built on high ground can
experience excessive draught, a steady draught of
between 1mm (0.04”) and 1.5mm (0.06”) W.G. is
required for satisfactory operation.
FLUE LINERS
Chimney’s lined with salt glazed earthenware pipes
are acceptable if the pipes comply with BS 1181 and
must be 125mm (5”). When lining an existing chim-
ney, a liner approved to BS 4543, Parts 1, 2 & 3
should be used. The liner should be secured at the
top and bottom by using closure/ clamping plate
firmly sealed and secured and an approved terminal
used at the top.
It is essential that every flue system be inspected
and tested by a competent person for its correct
effectiveness, to ensure that the combustion prod-
ucts are completely discharged to the outside
atmosphere.
FACTORY MADE INSULATED CHIMNEYS
Factory-made insulated chimneys should be con-
structed and tested to meet the relevant standards
and recommendations given in:
* B.S. 7566 - Installation of factory-made
chimneys conforming to B.S. 4543 for
domestic appliances.
Part 1: Method of specifying installations
design information.
Part 2: Specification for installation design.
Part 3: Specification for site installation.
Part 4: Recommendation for installation
design and installation.

VENTILATION AND COMBUSTION AIR
REQUIREMENTS
1. It is imperative that there is sufficient air supply
to the burner of the cooker in order to support
correct combustion.
2. The air supply to this appliance must comply
with BS 5410 Part 1.
3. The minimum effective air requirement for this
appliance is 65cm2. When calculating combus-
tion air requirements for this appliance use the
following equation: 550mm2per kW of maximum
rated output above 5kW. These requirements
are illustrated in OFTEC Technical Book No. 3 &
B.S. 5410.
4. If there is another appliance using air fitted in the
same or adjacent room, it will be necessary to
refer to B.S. 5410 to calculate the additional air
supply.
5. All materials used in the manufacture of air
vents should be such that the vent is dimen-
sionally stable and corrosion resistant.
6. The effective free area of any vent should be
ascertained before installation. The effect of
any gauze or screen should be allowed for when
determining the effective free area of any vent.
7. Air vents direct to the outside of the building
should be located so that any air current pro-
duced will not pass through normally occupied
areas of the room.
An air vent outside the building should not be
located less than the dimensions specified with-
in the Building Regulations (See Technical Data)
from any part of any flue terminal. These air
vents must also be satisfactorily fire proofed in
accordance with the current Building
Regulations.
8. Air vents in internal walls should not communi-
cate with bedrooms, bedsits, toilets, bathrooms
or rooms containing a shower.
9. Air vents traversing cavity walls should include a
continuous duct across the cavity. The duct
should be installed in such a manner as not to
impair the weather resistance of the cavity.
10. Joints between air vents and outside walls
should be sealed to prevent the ingress of mois-
ture. Existing air vents should be of the correct
size and unobstructed for the appliance in use.
11. If there is an air extraction fan fitted in the room
or adjacent rooms where this appliance is fitted,
additional air vents will be required to eleviate
the possibility of spillage of products of combus-
tion from the appliance/flue while the fan is in
operation. (Refer B.S. 5410).
12. Where such an installation exists, a test for
spillage should be made with the fan or fans and
other burning appliances in operation at full rate.
(i.e. extraction fans, tumble dryers) with all
external doors and windows closed.
13. If spillage occurs following the above operation,
an additional air vent of sufficient size to prevent
this occurrence should be installed. As a gener-
al guide an extra 50 cm2 of air vent free area will
be sufficient for most situations.
OUTSIDE AIR CONNECTION
This appliance may be connected direct to the out-
side of the house for its air supply.
1. If this option is used a special kit is available to
order.
2. Additional combustion air is not required as indi-
cated in B.S. 5410.
3. Remove air inlet plate on front right hand side,
replace it with the blanking plate located at back
left hand side (see fig.15).
4. The left hand side of the appliance must remain
open to provide cool air for the programmable
timer.
5. Connect the optional 125mm (5”) spigot to the
base. (see fig. 16)
6. To connect this cooker to an outside air supply
use the special order kit.
7. Air inlets traversing cavity walls should include a
continuous duct across the cavity. The duct
should be installed in such a manner as not to
impair the weather resistance of the cavity. This
duct should be satisfactorily fire proofed in
accordance with the current Building
Regulations.
8. Joints between air vents and outside walls
should be sealed to prevent ingress of moisture.

DOWN DRAUGHTS
However well designed, constructed and positioned,
the satisfactory performance of the flue can be
adversely affected by down draught caused by
nearby hills, adjacent tall buildings or trees. These
can deflect wind to blow directly down the flue to
create a zone of high pressure over the terminal. A
suitable anti-down draught terminal or cowl will usu-
ally effectively combat direct down blow but no cowl
is likely to prevent down draught due to a high pres-
sure zone. Ensure that any cowl used will not
restrict the flue exit or cause excessive back pres-
sure (See fig. 17) Refer to BS 5410.

DOMESTIC HOT WATER SYSTEM
(DHW MODEL ONLY)
SYSTEM
The DHW Model must be connected to a fully
pumped system.
Care should be taken to ensure that the domestic
hot water installation is correctly installed and that it
complies with all relevant codes of practice. If this
appliances is being connected to an existing system,
it is strongly recommended to check the following:
(a) That the system is sound.
(b) That the pipe work is adequately insulated.
(c) Check that the system is fitted with a circula
tion pump and a pipe stat and that both are
operating satisfactorily.
(d) Are there any modifications necessary to
make the domestic hot water system more
efficient.
SAFETY VALVE
A non-adjustable 3 bar safety valve must be fitted to
the primary flow pipe adjacent to boiler connection
ensuring that any discharge will not create a hazard
to occupants or cause damage to electrical compo-
nents or property.
NOTE: We strongly advise the use of pipe lagging
and also the use of a frost thermostat if the installa-
tion is likely to be exposed to situations where the
temperatures will drop to a level consistent with
frost.
Only competent personnel should be employed to
carry out any work on your domestic hot water sys-
tem.
It is important that no external control devices e.g.
economisers are directly fitted to this appliance
unless covered by these installation instructions or
agreed with the manufacturer in writing. Any direct
connection of a control device not approved by the
manufacturer could make the guarantee void.
PIPE FITTINGS
Materials used for installation work should be resist-
ant, sound and should conform to the current edi-
tions of the following or there equivalent:
1.1 Ferrous Materials
B.S. 4127: Stainless Steel Tubes
B.S. 1387: Steel Tubes
B.S. 1740: Steel Pipe Fittings
B.S. 6956: Jointing Materials
1.2 Non-Ferrous Materials

DIRECT DOMESTIC CYLINDER
A 227 Litre (60 Gallon) direct domestic cylinder can
be connected to this cooker using copper or stain-
less steel 28mm O.D. (1”) flow & return pipes. We
recommend that the cylinder is lagged along with
the pipework. (See Fig.20)
INDIRECT DOMESTIC CYLINDER
A 227 Litre (60 Gallon) indirect domestic cylinder
can be connected to this cooker using copper or
stainless steel 28mm O.D (1”) flow and return pipes.
We recommend that the cylinder is lagged along the
pipework (See Fig. 21)
15
Fig.20
Fig.21

We strongly recommend the fitting of a circulating
bronze pump on the return pipe to the boiler, con-
trolled by a pipe thermostat fitted on the flow pipe
within 6” (150mm) of the appliance.
PIPE THERMOSTAT
The fitting of a pipe thermostat to the common flow
pipe within 150mm (6”) of the cooker is recom-
mended in order to activate the water circulation
pump when the boiler reaches 60oC. This will
ensure that the return temperatures are maintained
and allow the pump to ‘run on’ to transfer any resid-
ual heat to prevent possible overheating.
NOTE: In line water conditioners fitted to the cold
mains supply both of chemical and magnetic type
are suitable for use with DHW cooker.

FUEL INSTALLATION
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 translu-
cent plastic containers.
An isolating valve should be fitted at the tank outlet,
in a 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. 23, 24, & 25 ).
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 recommen-
dations. Tanks should be located in the most unob-
structive position possible having taken safety, fill-
ing, 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 cop-
per tube complying to B.S. E.N. 1057. It can be
obtained in coil or half hard form for use with bend-
ing machines. This pipe can also be obtained with
protective plastic sheathing applied. Fittings for cop-
per pipe should be compression of the flared manip-
ulative 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 fit-
tings must not be used.
Screwed joints must only be made with tapered
threads complying to B.S. 1740: Part 1: 1971.
Jointing materials must be of types intended for use
with oil fuel. Special petroleum - resisting com-
pounds 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 under-
ground 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 fit-
ted 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
INDIRECT SYSTEM ONLY
To off-load excess hot water generated during
long cooking periods, it may be necessary to
install a heat sink radiator.
NOTE: Copper cylinder should be “finned-coil” type
with minimum capacity of 210 litres to B.S. 1566 &
B.S. 699.

oil supply system. (See Figs, 23, 24, & 25 ).
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 heat sensing phial of the fire valve
must be fitted to the clip provided in the burner com-
partment. 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.
The oil line is to be connected to the flexible oil hose
attached to the burner. Push the flexible oil hose
through the grommet on the left hand side of the
appliance.

SINGLE PIPE SUPPLY SYSTEM:
BOTTOM OF OIL STORAGE TANK ABOVE
BURNER (See fig.23 )
Single pipe supply system: Tanks servicing this
appliance by means of a single pipe need to be posi-
tioned so that they will apply the minimum head
required 1 meter (3’ 3”) of oil to the burner when the
fuel level is at its lowest point.
Refer to B.S. 5410 to calculate the additional head
requirement relating to pipe length and size.

OR LEVEL WITH BURNER
gravity feed to the burner can be maintained a two
pipe oil supply system may be adopted. (See fig.
24). The non-return valve in the supply line of the
two pipe system is required to prevent oil running
back from the burner and unpriming the oil pump.
The non-return valve in the return line is only
required if the top of the tank is above the burner. Its
purpose is to prevent oil running back through the
burner during maintenance.

SINGLE PIPE SYSTEM: WITH
DE-AERATION DEVICE BOTTOM OF
OIL STORAGE TANK BELOW OR LEVEL
WITH BURNER. (see fig. 25):
This system can be used where the tank base is
below the level at which gravity feed to the burner
can be maintained and the burner incorporates an
oil pump. The chamber is fitted close to the burner
and is linked to the tank by a single pipe, thus sav-
ing the return pipe required by the two pipe system
as described previously. Any air in the oil brought up
from the tank is bled off in the de-aeration chamber.
De-aeration chambers must always be installed
externally to buildings because they emit small
quantities of vapour. The chamber is connected to
the oil pump in the burner of the appliance by a nor-
mal two pipe loop.
These requirements are fully explained within the
following documents:

False light at start
If oil is released and no flame is established the con-
trol will cut out within the safety time of: 10 seconds.
Flame failure in operation
In the event of flame failure in operation the oil sup-
ply is cut off and the control restarts the burner as
described under the heading “Normal Start”. On
flame failure, immediately after burner start, the con-
trol will initiate re-ignition.
Flame monitoring
The flame is monitored by a photocell unit. Note: In
accordance with the latest ISO and DIN standards,
type LOA activates the safety relay if the photocell
unit is exposed to light in the pre-purging period.
Control of flame signal
The photocell current is measured with a d.c.
ammeter (moving coil instrument) which is connect-
ed in series with the photocell unit. Min current for
flame indication: 35 µA.
