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).

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

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 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 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 left from burning solid fuels.
ALTHOUGH THE CHIMNEY MAY HAVE BEEN CLEANED OF LOOSE SOOT PRIOR TO INSTALLATION, 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
