This appliance has been tested and approved in accordance with Gas Appliance Directive (90/396/EEC), the
Low Voltage Directive (72/23/EEC) and the Electromagnetic Compatibility Directive (89/336/EEC) as
amended.

LOCATION
Prior to installation, ensure that the local distribution
conditions (nature of the gas and gas pressure) and
adjustment conditions are compatible. The
adjustment conditions for this appliance are stated
on the data badge which is fitted inside the bottom
burner door.
When choosing a location for this appliance you
must have:
(a) Sufficient room for the installation (see
clearances), a satisfactory flue (see flue
system), and an adequate air supply for correct
combustion and operation (see Ventilation &
Combustion Air Requirements).
(b) Adequate space for maintenance and air
circulation.
(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
available 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 (U.K.), B.S. 7462, &Safety
Document 635, ETC: Part 1 section 5.6.4 & The
Electricity at Work Regulations. The cooker requires
a 230V - 240V, 50Hz supply. Connection of the
appliance and any system controls to the mains
supply must be through a moulded on plug top, (with
a 5 Amp fuse fitted) which is fitted to the appliance
in accordance with EN 60335, Consumer
Protection, SI 1994 No. 1768, plug and sockets etc.
(safety) Regulations 1994.
Always install in accordance with current local wiring
regulations.
WARNING: THIS SUPPLY MUST BE
EARTHED (Refer to B.S. 7430 : Code for
Practice of Earthing).
Where a risk of low voltage can occur, a voltage
sensitive device should be fitted to prevent start up
of the burner so as not to endanger the installation.
Primary fuse is located in the control box tray.
To isolate the appliance completely unplug from the
mains socket. Always ensure that this socket is
easily accessible and close to the appliance.
Persons in charge of this appliance should be aware
of this socket outlet position.
CLEARANCES TO COMBUSTIBLES
When bringing your kitchen units up to the sides of
the cooker, leave a 10mm gap between the Stanley
and adjacent units, this gap can be reduced by fitting
an optional hob side filler strip to the Stanley leaving
a 5mm gap (see fig. 2 & 3). Likewise the base of
your units can be brought up flush to the Stanley’s
built-in plinth.
When bringing the work top up to the side of the hob
leave a 10mm gap to combustible material (see
fig.2).
Fig 2
Fig 3
Fig.4
Where the flue passes through a combustible
material a twin wall solid packed insulated chimney
connector 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.
4)
When installing a non combustible worktop, it is
necessary to allow adequate clearance for the
removal of the hob.
FLUE SYSTEMS
PRE-INSTALLATION CHECK
Before installing your appliance, check that the
chimney is clean and clear of obstructions. Cracked
brickwork and leaking joints should be made good.
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 flue serving another appliance.
Always ensure that the connection is to a chimney of
the same size - never connect to one of smaller
dimensions. Flues wholly constructed of single skin
pipe are not recommended under any
circumstances. Due to their inability to retain heat
such flues will inevitably give rise to the formation of
condensation.
Fig. 5
CHIMNEY’S
Generally the most effective chimney for gas is one
that is straight, avoid offsets and terminate with a
straight sided pot.
IT IS NOT RECOMMENDED TO CONNECT TO A
FLUE SMALLER THAN 150MM (6”) OR IN
EXCESS OF 175MM (7”) DIAMETER.

SEALING
This cooker and flue system operate under a
positive pressure, it is essential that all flue joints
are tightly sealed against flue gas leakage and
tested accordingly (see Fig. 8).
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 hob
back filler piece and flue pipe collar rosette is
available as an optional extra. (see fig. 9).

(6”) Diameter

NOTE: Never connect to a chimney or flue system

Fig.8a
FLUE HEIGHT
The flue must be high enough 4.5 mts. (15ft)
minimum 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 chimney stacks, etc. The terminal position
should be in accordance with B.S. 5440 Part 1 and
the Building Regulations:
FLUE SYSTEM
Where the standard masonry chimney is not
available, a proprietary type of non-combustible or
non-corrosive material 150mm (6”) twin wall fully
insulated pipe may be used. The pipe must
terminate at a point not lower than the main ridge or
adjacent outside obstructions. With such
installations, access to the chimney must be
provided for cleaning purposes.

Horizontal runs more than 450mm (18”) and 90°
bends numbering more than 2 per installation should
be avoided. If it is necessary to offset the chimney
the recommended angle is 60° to the horizontal and
the statutory minimum is 45° (see fig. 10).
CONNECTIONS
A cast iron 90° bend with cleaning door is available
with the cooker. A vertical cast iron outlet pipe with
cleaning door is also available. A flexible flue
adaptor is supplied, this is to connect the cooker
150mm (6”) bend or straight pipe to the 150mm (6”)
chimney liner.
ALL FLUE CONNECTIONS MUST BE
THOROUGHLY 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.
WHERE THE APPLIANCE SPIGOT OR FLUE
PIPE PROTRUDES INTO THE CHIMNEY, CARE
SHOULD BE TAKEN TO ENSURE THAT IT DOES
NOT BLOCK THE CHIMNEY.
SUITABLE MATERIALS
* Mineral Fibre cement pipes conforming to B.S.
7435.
* Sheet metal conforming to B.S. 715. & B.S.
4076.
* Insulated metal chimneys conforming to B.S.
4543 and B.S. 5440 (a galvanised finish is not
suitable).
* Clay flue linings conforming to B.S. EN 1457.
* 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.
Fig. 10
USE OF EXISTING FLUES AND CHIMNEYS
When connecting to an existing chimney it is
necessary to line the flue using approved 150mm
(6”) 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 normally
be used for this appliance provided that its
construction, condition and dimensions are
acceptable. Flues that have proved to be
unsatisfactory, particularly with regard to down
draught, must not be considered 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. 5440: Part 1 should be

Before connecting this appliance to a chimney or
flue pipe which has previously been used with
another fuel, the chimney or flue pipe should be
thoroughly swept and lined accordingly.
All register plates, restrictor plates, damper etc.
which could obstruct the flue at a future date should
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 the inside wall, so as to prevent
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 from this appliance will
have a descaling effect on hardened soot deposits
