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) S u fficient room for the installation (see

clearances), a satisfactory flue, 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 (1

1

/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
appliance 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 a risk of low voltage (below 190 volts) 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 at rear of
control box.

Always install in accordance with current local
wiring regulations.

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.

REDUCED CLEARANCES

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.6).

FLUES

The chimney and flue pipes intended for use with
this appliance should be mechanically robust,
resistant to internal and external corrosion, non­combustible, 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
combustion 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

Fig. 10

PRE-INSTALLATION CHECK

Before installing your cooker, check that the
chimney 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

N o t e : Fill voids and area around liner with

vermiculite or a comparable approved material.
(See Fig. 11 & 12)

CHIMNEY’S

Generally the most effective chimney for gas is one
that is straight, avoid offsets and terminate with a
straight sided pot.

Fig.11

unprotected mild steel or other material which is
likely to corrode.

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
appliance. Always ensure that the connection is to
a chimney of the same size. Chimneys wholly
constructed of single skin pipe are not
recommended under any circumstances. Due to
their inability to retain heat such chimneys will
inevitably give rise to the formation of condensation.

Flue greater than 125mm

(5”) 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. 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.

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.

Refer to Flue Assembly Instructions sheets. See
Fig.13)

CONNECTIONS

A cast iron 90° bend with cleaning door is supplied
with the cooker, along with a cast iron spigot for
connection 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.

Fig.13

Note: Never connect to a chimney or flue system
serving another appliance.

Fig.14

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
chimney.

Fig. 12

The terminal position should be in accordance with
B.S. 5440 Part 1 & the current Building Regulations.

If it is necessary to offset the chimney the
recommended angle is 60° to the horizontal and the
statutory minimum is 45° (see fig. 14).

10

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.

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. 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
necessary 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
normally be used for this appliance provided that its
construction, condition and dimensions are
acceptable. Flues that have proved to be
u n s a t i s f a c t o r y, 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 must be
thoroughly 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
INSTALLATION, IT IS IMPERATIVE THAT THE
CHIMNEY IS INSPECTED FOR SCALED SOOT
PA RTICLES AFTER THE FIRST MONTH OF
O P E R ATION AND ANY LOOSE MAT E R I A L S
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
chimney, a liner approved to BS 715 and 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
e ffectiveness, to ensure that the combustion
products are completely discharged to the outside
atmosphere.

FACTORY MADE INSULATED CHIMNEYS

Factory-made insulated chimneys should be
constructed 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.

V E N T I L AT I O N A N D COMBUSTION AIR
REQUIREMENTS

It is imperative that there is sufficient air supply to
the burner of the cooker in order to support
combustion.

Detailed recommendations for air supply are given
in BS 5440 Part 2. The minimum effective air
requirement for this appliance is 44cm2. When
calculating combustion air requirements for this
appliance use the following equation: 5cm2per
each kW of rated input above 7 kW.

If there is another combustion appliance fitted in the
same or adjacent room, it will be necessary to refer
to B.S. 5440: Part 2 & I.S 813 to calculate the
additional air supply.

All materials used in the manufacture of air vents
should be such that the vent is dimensionally stable
and corrosion resistant.

The effective free area of any vent should be
ascertained before installation.

Air vents direct to the outside of the building should
be located so that any air current produced 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 within 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.

Air vents in internal walls should not communicate
with bedrooms, bedsits, toilets, bathrooms or rooms
containing a shower.

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.

Joints between air vents and outside walls should be
sealed to prevent the ingress of moisture. Existing
air vents should be of the correct size and
unobstructed for the appliance in use.

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 alleviate the
possibility of spillage of products of combustion from
the appliance/flue while the fan is in operation.
Refer to B.S. 5440 Part 2 and the Gas Safety
(Installation & Use) Regulations as amended.

Where such an installation exists, a test for spillage
should be made with the fan or fans and other gas

burning appliances in operation at full rate. (i.e.
extraction fans, tumble dryers) with all external
doors and windows closed.

If spillage occurs following the above operation, an
additional air vent of sufficient size to prevent this
occurrence should be installed. As a general guide
an extra 50cm2of air vent free area will be sufficient
for most situations.

OUTSIDE AIR CONNECTION

This appliance may be connected direct to the
outside 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

indicated in B.S. 5440 Part 2.

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. Connect the optional 125mm (5”) spigot to the

base, see fig. 16

5. To connect this cooker to an outside air supply

use the special order kit.

6. 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 as per
Building Regulations.

7. 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
usually effectively combat direct down blow but no
cowl is likely to prevent down draught due to a high
pressure zone. Ensure that any cowl used will not
restrict the flue exit or cause excessive back
pressure (See fig. 18) Refer to BS 5440 Part 1.

Fig. 16

Fig.17

Fig. 18

METERS (NATURAL GAS)

A suitable gas meter must be connected to the
service pipe either by a representative of the gas
supplier or by an appointed contractor. If using an
existing meter have it checked to ensure that the
meter is capable of dealing with the total rate of gas
supply needed (see Technical Data).

GAS PIPE SIZE

It is important that the correct service pipe size be
used in order to ensure an adequate gas supply of

1.48 cubic meters/hr (52.5 Cubic ft./hr) for Natural
Gas or 0.59m3/hr (20.8 ft3/hr) for LPG. This depends
on the distance between the supply meter, the
pressure drops caused by bends and the expected
pressure drop in the gas mains at peak demand
times. (See B.S. 6891).(If in doubt contact your local
gas supply company)

13

GAS CONNECTION

A shut off valve must be fitted as close as possible
(See Fig.20) to the cooker and should be accessible
at all times. A combined valve and elbow fitting is
supplied with the appliance, located in the oven
package. One end of this fitting simply fits onto the
gas train located at the bottom left hand side of the
cooker. The other end has a 3/4” BSP Male thread.
If it is necessary to use an alternative valve, select
a valve which does not cause a restriction in the flow
or a pressure drop across it when open, and install
it as close as possible to the cooker.

NOTE: Clean off any excess pipe compounds from
connections.

A FLEXIBLE HOSE MUST NOT BE USED TO
CONNECT THE GAS SUPPLY TO THE COOKER.

Fig.19

WARNING: To avoid pipe sealing compounds from
entering into the gas train, do not apply sealing
compound to the first two threads at the tip of the
gas connection. (See Fig.19)

GAS PIPES AND FITTINGS

Materials used for installation work should be fire
resistant and gas tight and should conform to the
following or their equivalent:

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 circulation

pump and a pipe stat and that both are
operating satisfactorily.

(d) Check if there are 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
components or property.

NOTE: We strongly advise the use of pipe lagging
and also the use of a frost thermostat if the
installation 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
system.

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
resistant, sound and should conform to the current
editions 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

We strongly recommend the fitting of a circulating
bronze pump on the return pipe to the boiler,
controlled 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
recommended 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 residual 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.

Fig.25

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.

LEAVE ALL DOCUMENTS WITH THE END USER

COMMISSIONING OF BURNERS

The burner used in the Brandon Gas cooker is the
standard Ecoflam Azur 30 burner thus ensuring that
spare parts are readily available. The burner uses a
Honeywell VK4100 gas valve.

The Landis and Gyr control box has a programme
indicator which aids fault finding. A full description of
the programme indicator is given on page 19.

The following checks must be carried out when
commissioning the burner:

1. Gas Pressure & Rates

The gas pressure is checked by connecting a
manometer to the test point on the burner. The
burner pressure is set by adjusting the gas pressure
adjuster screw. Note: This adjuster screw is very
sensitive to even small adjustments so the gas
pressure must be set accurately. Consequently the
manometer used must be graduated in mbar or be of
a higher resolution. Check to make sure that the gas
rate is correct (see technical data).

2. Air Setting

The CO2 operating level for the burner is measured
at a test point using a combustion gas analyser (See
Fig.27). The CO2 level must be set to within the
operating ranges specified below. This is achieved
by moving the air adjuster on the burner. (See
Fig.28)

Fig.28

Fig.27

3. Ionisation Current

The ionisation current for the burner must be
measured. This is done by removing the link on the
test block and connecting an amp meter across
both terminals of the block. (See Fig.29 & 30)

Pressure Switch The control box checks that the

air pressure switch has switched
by testing that continuity no
longer exists between pins 3 and

6. If this is found to be
satisfactory the control box will
continue to the pre-purge stage.

P

Description of Landis and Gyr control box.

The following is a description of the start up
sequence of the control system. The corresponding
control box programme indicator symbol for each
step is shown in the left hand column.

Step Description
Turn on oven When the oven thermostat is

thermostat. turned on power is supplied to

the oven control box which start
immediately. The oven pressure
switch closes. The indicator cam
on the control box then rotates
to the start position.

Waiting Time During this interval the “No Air”

signal is checked by testing the
continuity between pins 3 and 6.
The control box also carries out
an internal check that it is not
receiving an ionisation flame
signal. At the end of this period
a signal is sent from pin 3 on the
control box.

Pre-Purge The pre-purge period will last

approximately 30 seconds. The

>>>> control box checks continuity

between Pin 3 and Pin 11. It
also checks that Pins 7 and 9

are linked.

Ignition The transformer sparks and the

1. gas valve opens for 5 seconds.

Flame Signal A flame signal must be present

2. to hold the gas valve in the open

position.

l l l l Full load operation.

Operating Position.

NOTE:

1. If the control box is interrupted during its
starting sequence it must continue through to
the end of this sequence before it can start a
new sequence. This may sometimes make the
start-up of the appliance seem very long.

2. If air on the operating burner is not proven at
start up or is lost during operation the pressure
switch will open and the control box will lock
out.

TROUBLE SHOOTING

These checks must be undertaken by a trained and
competent person.

Burner motor will not start, reset button not
illuminated:

1. Check for electrical supply at the fuse holder.
If no supply exists check external wiring.

2. Check for electrical supply at terminal 12 on
the control box. If there is electrical supply at
the fuse but not at terminal 12 check the
following.

A. Check if high limit thermostat has tripped

out.
B. Check the operation of the time clock.
C. Ensure that the control thermostat is

functioning properly.

Burner will not start, reset button illuminated:

1. Press the reset button located under the
bottom left door if cooker still goes to lockout.

2. Remove control box from front panel, and note
the position of the control programme indicator
underneath the reset button when the button is
lit up.

P Signals a problem with the pressure switch:

1. Check that air pressure switch is closing by
testing for phase on terminal 2 in the pressure
switch. The phase should switch from
terminal 1 to terminal 2 when the fan is
powered on. (See Fig.31)

2. Check air pressure switch setting and burner
air setting.

3. Check for adequate air supply.

4. Check for blockage in chimney.

If the dial stops at 1 this denotes a problem at
ignition:

1. Check gas supply is at the correct pressure,
check that gas valve is energised and
operating during safety time.

2. Check that ignition spark is present.

3. Check that the flame detection probe is
positioned correctly in the flame. Ensure that
the probe insulation is sound, free from cracks
or moisture, check that probe is not in contact
with other metallic parts of the burner.

4. Check that burner is effectively earthed and
bonded to the incoming earth wire from the
mains supply.

5. Check the burner air setting and the gas
adjuster setting.

Burner will not start, control programme
indicator rotates continuously:

1. Check wiring air pressure switch. (See Fig.31)

2. Check air pressure switch by checking for
phase on terminal 2 in the pressure switch.
