The mean flue gas temperature directly downstream of the flue spigot at nominal heat output is 308ºC.

This appliance is not suitable for installation in a shared flue system.

The minimum clearance to combustible materials is 150mm.

Checking existing chimney

The internal and external condition of the chimney should be checked before the appliance is installed and rectification made where necessary to prevent leakage or porosity. The soundness of the chimney which should have a minimum flue dimension of 175mm square or 185mm diameter can be confirmed by smoke testing. Advice on the test method can be obtained from HETAS.

When repairing or re-using chimneys its recommended that the building control office be consulted before the commencement of work with particular attention to the chimney height and its termination.

The chimney must be swept before installation.

Erecting New Chimney

The flue through the chimney should be formed with pre-cast moisture and acid-resistant liners with a minimum internal dimension of 185mm square and all in accordance with the current Building Regulations (England and Wales) and in

Scotland the Building Standards (Scotland) (Consolidation)

Regulations and the Codes of Practice for chimneys and flues

BS. 6461 Part 1 and BS 7566 Parts 1 to 4.

Ensure the chimney liners are free of projecting internal building jointing composition before the appliance is installed.

Factory made Insulated Chimneys

It is recommended the chimney be ceramic lined and comply with BS. 4543.

The minimum diameter for a straight chimney is 175mm and if offsets are fitted the recommended minimum diameter is

200mm.

There are two Isokern pumice liners which are also recommended. One is the standard 175mm diameter and the other is a 170mm thin wall. The thin wall has a smaller outer diameter and is designed to fit an existing chimney system.

Fig. 4

DESN 515208 A

A minimum 6” vertical length of flue pipe must be fitted before any bend is included.

FLUE LAYOUTS

In Fig. 2. the cooker is installed in an existing recess. There must be a clearance of not less than 150mm between the top of the flue pipe and any overhanging brickwork.

Any cavities or pockets above the register plate should as far as possible be filled and if necessary the flue pipe should be extended into the throat of the chimney and soot door provided for chimney sweeping.

If a flue liner or insulated chimney is used, the size should not be less than 185mm square or 200mm diameter, and 175mm diameter respectively.

There are two Isokern pumice liners which are also recommended. One is the standard 175mm diameter and the other is a 170mm thin wall. The thin wall has a smaller outer diameter and is designed to fit an existing chimney system.

Both have a lifetime guarantee.

In Fig. 3, the cooker is connected direct to a brick flue.

Horizontal pipe runs between cooker and brick flue must not be used.

In Fig. 4, the cooker is connected to an existing brick flue with a length of flue pipe. Square bends and horizontal runs must not be used. There must be a cleaning door at every bend.

NOTE: WHATEVER METHOD OF INSTALLATION IS

EMPLOYED, AIR MUST NOT BE ALLOWED TO ENTER THE

CHIMNEY EXCEPT THROUGH THE COOKER. ALL JOINTS

MUST BE AIR-TIGHT.

If the chimney is unlined, and there is any doubt about its condition, it should be lined in accordance with current Building

Regulations.

PROVISION MUST ALWAYS BE MADE FOR SWEEPING

THE CHIMNEY.

IMPORTANT: CEMENT TYPE PIPES AND FITTINGS MUST

NOT BE USED WITHIN 2m. OF THE COOKER. CHIMNEYS

OF PLAIN PIPE ARE NOT RECOMMENDED BUT CERTAIN

PROPRIETARY MAKES OF INSULATED CHIMNEY ARE

SUITABLE.

AIR SUPPLY

Provision must be made for a permanent unobstructed air vent having a minimum effective area of 50cm

2 communicated directly to outside air or an adjacent room which itself has a permanent air vent of at least this size direct to outside air.

If a flue draught stabiliser is fitted in the flue this appliance requires a permanent open air vent of 92 cm

2

.

Any air inlet grilles must be positioned so that they are not liable to blockage.

It is not permissible to use an air extraction device in the same room as the appliance, unless additional ventilation is provided to prevent any adverse effect on the flue.

Effect of Extractor Fan

Avoid if possible the installation of an extractor fan in the same room as the cooker. Compensating air inlets must be introduced equivalent to the capacity of the fan when fitted.

CENTRAL HEATING AND

HOT WATER SYSTEM

THIS APPLIANCE MUST NOT BE USED WITHOUT WATER

CONNECTED.

It is recommended that a 190 litre (40 galls) indirect hot water storage cylinder of the double feed type e.g. (Manufactured by

Albion Cylinders, complying with BS. 1566 Part 1:DF Type 10) should be lagged and fixed vertically as near as possible to the cooker.

The 28mm minimum diameter primary flow and return pipes must not exceed 10m in length and pipes longer than 5m must be lagged.

Ensure that the flow pipe has an open vent and rises continuously from the boiler to the cylinder to ensure good gravity circulation.

In combined systems, the water draw-off pipes to the taps must be dead-leg connection from the vent/expansion pipe.

There are only two boiler tappings on this cooker and a typical design layout is shown in Fig. 5.

An injector tee is provided which must be fitted to ensure adequate primary flow circulation when the water circulator is operating, otherwise there may be a lack of domestic hot water.

The heating flow and return pipes may be 22mm, the return pipe being connected to the 28mm primary return by the injector tee, and the tee outlet connected to the boiler return pipe.

All installations must be fitted with a drain tap at the lowest point of the system.

Inhibitor

A corrosion inhibitor MUST be added to the heating system to protect the heat exchanger and pipework. Inhibitor must also be replaced if the system is drained after installation. As a precaution, the heating system MUST also be flushed out prior to the addition of the inhibitor to ensure any flux, debris is removed.

BOILER - Control

In order to maximise the life of your boiler body, an electrical thermal re-set low temperature boiler thermostat has been fitted within the appliance, behind the LH side removable cover, whose purpose is to isolate the electrical power from the water circulator when the boiler thermostat falls below 60ºC (140ºF) and thus minimise harmful condensation on the boiler surfaces.

The 3 core 0.75mm

2 cable lead from the appliance must be connected to/from the water circulator as indicated on the

‘Typical Wiring Diagram’ in Fig. 6. Marked ‘Boiler Low

Temperature Return Thermostat’ - This switch is normally closed during cooker operation and will open when the water temperature falls preventing chilling of the boiler.

NOTE: IF THERE IS A POSSIBILITY OF BOILING TAKING

PLACE A REVERSE ACTING THERMOSTAT SHOULD BE

FITTED TO THE DOMESTIC HOT WATER CYLINDER OR

BOILER PRIMARY FLOW PIPES, AND ELECTRICALLY

CONNECTED TO THE CENTRAL HEATING PUMP, THIS

WILL SWITCH THE PUMP ‘ON’ TO PREVENT BOILING. AT

LEAST ONE RADIATOR (USUALLY THE BATHROOM)

SHOULD NOT BE FITTED WITH A TRV (THERMOSTATIC

RADIATOR VALVE), TO ACT AS A HEAT LEAK, SHOULD

THE BOILER OVERHEAT AND THE PUMP FAIL TO START.

HIGH UPDRAUGHTS

Tall chimneys may develop excessively high updraughts which prevent the appliance operating correctly.

It is recommended that a proprietary brand adjustable flue draught stabiliser having an openable cross sectional area of

182.5sq cm (6”ø pipe) be fitted above the flue pipe connection, either in the brickwork or into a right angle ‘T’; fitting in the flue pipe position that will not inconvenience appliance operation or maintenance.

GENERAL - Firebrick Positions and Replacement

The Rayburn 345W is delivered complete including a set of boiler removable firebricks where positional location determines the amount of hot water supplied in winter and summer seasons.

The oven side and firebox front firebricks are permanently fixed with fire cement, whilst the two boiler face side bricks and boiler back brick are located for the summer season thereby providing domestic hot water only. For winter use or central heating facilities, the boiler face rear brick is removed and the boiler face side bricks are transferred to locate on/over the oven side firebricks. See Fig. 7 & 7A.

The firebricks fitted to the Rayburn Cookers are of first quality manufacture, and providing the cooker has been installed and used correctly will have a reasonable life. These are, however, expendable items and in time will require renewal. The renewal of firebricks is not a major operation and can be carried out by the average handyman. Replacement bricks either in sets or singly can be obtained from your Rayburn Distributor. Quote the serial number which will be found on the appliance data plate.

INSTALLATION

Place the cooker in the intended position and lift out the surface ground hotplate, checking that the joint between the underside of the hob and the top of the cooker is intact.

Any joints which have opened should be made good with fire cement provided.

If the appliance is installed near combustible material then as well as adhering to minimum clearances in Fig. 1 additional non-combustible insulation must be fitted to the wall to protect the area around the flue and fluebox. The insulation must reach a minimum distance of 150mm either side of the flue/flue box and follow the line of the flue. The minimum specification for this material is Superwool 607 LTI with a density of 320kg/m3, a thickness of 10mm and a self finish. There must be a minimum 16mm air gap between the insulation board and an adjacent combustible wall surface. A higher specification material may be used but the air gap must be maintained

.

Check that the boiler/cooker flueway dampers operate correctly by turning the knob on the front plate adjacent to the top left hand corner of the roasting oven door.

NOTE: IT IS NOT VISUALLY POSSIBLE TO SEE THE

BOILER DAMPER AND THIS SHOULD BE CHECKED BY

FEELING THROUGH THE HOTPLATE APERTURE TO THE

BACK OF THE COOKER. THE COOKER DAMPER SPINDLE

OPERATES THE BOILER DAMPER WHICH CAN BE FELT

BY INSERTING HAND INTO FLUEWAY.

Replace the hotplate making sure that it is seating evenly on the soft rope and that it is approximately 1.5mm proud of the enamelled top plate, with an equal space all round.

1. Connect pipework to boiler flow and return tappings.

2. Fit the flue chamber which should have a rope seal already installed. The flue chamber is screwed to the cooker making a good seal as any air leak at this point will impede the working of the cooker.

3. Open the firebox and ashpit doors and check that the reciprocating bottomgrate bars are in position, and the 3 grate plates are in place. The riddling lever will not operate fully as these plates, if fitted correctly, will lock the reciprocating bars.

4. Turn the boiler thermostat knob at the rear left hand corner of the top plate from No.1 (low) to No.8 (high).

NOTE: THE HIGHER THE NUMBER, THE HIGHER THE

WATER TEMPERATURE.

The handrail brackets are held on the front ends of the cooker top-plate casting. Remove the travel nuts and replace with the handrail brackets ensuring the fibre protecting washers are in position. Insert the handrails with fitted endcaps into the brackets, positioning them correctly, and tighten the locating bolts (Fig. 9).

TESTING AND COMMISSIONING

After completing the installation, the heating contractor should demonstrate to the user the operation of the appliance and the routine cleaning method.

The protective grease should be removed from the hotplate before lighting.

Check that the system is full of water and free from air locks.

When lighting, check that the cooker flueway damper is set to

‘C’ cooker, the flue box damper is fully out and the chamber door is closed, The thermostat should be at 8, maximum and the spinwheel open. The secondary air slide inside the firebox door should be set to open. These settings will allow maximum draught for the firebox and flue. The cooker must not be left in this condition, as the open spinwheel is not controlled thermostatically.

The firebox door and the ashpit door are interlocked so the top door has to be opened before the bottom. Add paper and kindling to the grate and light. Close both doors. After a few minutes the fire should pick up and gradually add larger pieces of fuel. Allow the cooker to establish the fire and gradually reduce the amount of air going into the firebox. Start closing down the spinwheel, so that the cooker is working on the thermostat. It may be that in normal running the spinwheel needs to be slightly open depending upon the heat requirement.

For the first couple of days do not overfire. The cast iron inside the cooker will build up heat gradually and overfiring may cause damage.

NOTE: SMOKE/SMELL EMITTED DURING INITIAL USAGE

Some parts of the cooker have been coated with a light covering of protective oil. During initial operation of the cooker, this may cause smoke/smell to be emitted and is normal and not a fault with the appliance, it is therefore advisable to open doors and or windows to allow for ventilation. Lift the lids to prevent staining the linings.

Flue Restrictor Plate

This plate is fitted at the rear of the firebox covering the flueway opening and is to be used when burning wood.

This part can only fit one way round. Fit this part before the grate plates and side bricks.

Grate Plates

Three Plates are supplied with the cooker and are fitted over the grate bars when burning wood. Fit the plates, with the return edge downwards, evenly front to rear. The grate plates will have the effect of locking the riddling

mechanism so when burning wood, riddling is not necessary. Position the riddling handle centrally in its slot to align the grate bars before fitting.

WARNING: HOT SURFACES, use the tool supplied to operate this appliance. It is recommended to use the heatproof glove supplied when raising the dome lids to use the hotplate. Replacement gloves can be obtained from the AGA Shop.

RECOMMENDED FUELS

Fuel should be stored under cover and ventilated, and kept dry. Wet kitchen refuse should not be burned.

The appliance has been tested using wood logs only.

It is not suitable to burn solid mineral fuels.

CHIMNEY FIRES

Prevention: Chimney fires do not occur in clean, intact, properly installed chimneys. Have a professional chimney sweep clean and inspect your appliance at least once a year. More frequent cleaning may be required, based on the type of fuel burned and the frequency of use. In general, an older appliance or one that is used frequently, will require more than one clean per year.

Detection: The first indication of a chimney fire is usually the noise - a roaring sound grows louder as the fire’s intensity increases. Clouds of black smoke and sparks will be seen exiting the top of the chimney; in severe fires, flames can extend several feet about the chimney.

Action: In case of a chimney fire follow these steps but do not put yourself or others in peril:

1. Call the fire brigade immediately.

2. Get everyone out of the property.

3. Close down the air supply to the appliance i.e. the primary air spinner and the flue damper. Limiting the fires air supply will reduce its intensity. If there is a damper in the chimney connector, plug or close the opening.

4. If a fire extinguisher is available, open the appliance door just enough to insert the nozzle of a 10lb, dry chemical fire extinguisher rated for Class ABC fires.

Discharge the entire content of the fire extinguisher into the appliance and shut the door.

5. If possible, wet down the roof and other outside combustibles to prevent fires ignited by shooting sparks and flames.

6. Closely monitor all combustible surfaces near the chimney. During severe chimney fires, these surfaces can become hot enough to ignite.

After a chimney fire, have the chimney inspected by a professional chimney sweep or cooker installer.

OVEN DOOR OPERATION - SEE FIG. 2

To open the doors. Twist the handle slightly to lift up the door catch from the locking spindle and pull the door open.

To close the doors. Gently push the door shut until the door catch makes contact with the locking spindle.

FIREDOOR/ASHPIT DOOR OPERATION

The fire door and ashpit door are kept closed by a turn screw. A tool is supplied to operate these when hot and they can be adjusted to ensure both these doors close tightly. IT IS IMPORTANT TO ENSURE PROPER

CLOSURE OF THESE DOORS TO PREVENT

OVERFIRING.

FUELLING WITH WOOD OR PEAT

The cooker will satisfactorily burn wood logs, blocks or peat briquettes, but logs should be perfectly dry in order to obtain the best cooker performance and minimise the deposits of creosote. Wet logs may also provide overnight banking problems and the following hints are recommended:a) Burn dry soft wood in the day time and dry hard wood overnight if possible.

b) Avoid using ‘green’ wood on overnight banking as creosote deposits will be increased.

c) Using hard wood in the day time will give prolonged burning but heating response is slower.

d) Wet kitchen refuse should not be burned.

e) Before refuelling, open the flue chamber damper to its full extent and fill the firebox up to the bottom of the firedoor opening.

f) To obtain the optimum burning rate when burning wood logs, the grate plates should be fitted to the top of the firebars in the firebox. Riddling is not required, poking will normally suffice. Take care not to upset the plates when using the poker.

COOKER CONTROL

Heating Only

a) The fire is controlled by using the spinwheel on the ashpit door to govern the air supply.

b) The adjustable flue chamber damper is for reducing the chimney draught, and the more it can be closed, the easier the cooker is to control. The line markings on the flue chamber enable you to repeat the best settings to suit your chimney, from No.1 in a closed position to No.6 fully open. Try a midway point first.

c) Control over the direction of the flue gases is

obtained by the setting of the cooker/boiler damper.

Set the cooker/boiler damper knob on the front of the cooker to ‘C’ and the boiler thermostat knob on the rear left hand corner of the top plate, to No. 2 or 3. If more heat is required set to a higher number and open the spinwheel.

NOTE: INTERMEDIATE SELECTIVE SETTINGS OF

Set the spinwheel open. The precise amount will be shown by experience with the appliance, 2-3 turns will do to start.

After setting the cooker/boiler damper knob to ‘C’, set the flue chamber damper fully open after refuelling and reset to position which has been found by practical experience to give the best results. Do not try to obtain a fast increase in temperature by opening flue chamber to its fullest extent. This results in most of the heat being wasted up the chimney.

Avoid excessive fire temperatures - they are unnecessary and may do serious harm to the cooker.

The first symptoms of an overheated cooker is the formation of clinker (melted ash) which will damage the fire bricks.

Damaged firebricks should be replaced as soon as possible but may be temporarily repaired with fire cement.

Keep the ashpit door securely closed with the front plate catch.

BOILER CENTRAL HEATING

THERMOSTAT SETTING

Set the cooker/boiler damper knob ‘H’.

Close spinwheel.

To regulate burning, set the boiler thermostat knob to ‘8’

(high) or minimum rate ‘1’ (low).

Adjust as required to suit desired water heating.

Overnight banking and daytime slow burning should be obtained with the boiler thermostat knob set at ‘1’ to give extended burning. This maybe higher and will be dictated by personal choice.

Some woods are more difficult to burn therefore it may be necessary to open the spinwheel in addition to the thermostat to obtain the desired results. The spinwheel must be closed as appropriate. Do not leave the cooker for extended periods with the spinwheel open as the cooker may overheat and cause damage.

In some circumstances, it may be possible to overheat the appliance and the water inside will boil. This will be evident by the sound of a knocking noise coming from the appliance and pipes around the house. If this occurs, close off all air controls and manually start the central heating pump if fitted. Opening the oven doors and hotplate covers will help to release heat from the appliance. Be aware that steam and boiling water will be expended from any open vent from the heating system probably in the roof space at the expansion tank.

In the unlikely event that the appliance is not operating in freezing conditions, the water must be drained from the boiler to prevent frost damage.

OVERNIGHT BANKING

Wood

The appliance is designed for continuous slumbering overnight for up to a maximum of 10 hours depending on the type of dry wood being used. Last thing at night, close the flue chamber damper. De-ash the fire, empty the ashpan and fully refuel. It may be necessary to open the flue chamber door.

Ensure that the firebox and ashpit door are securely

closed, close the spinwheel tight and the flue chamber damper is set to No. 1.

Set the boiler thermostat knob to its minimum setting and front damper knob to ‘c’.

Turn the flue dilution lever (See Fig. 7) from left to right hand so that the flue chamber door opens at the bottom and minimise burning rates.

NOTE: THE PRECISE AMOUNT OF OPENING

DEPENDS ON THE CHIMNEY DRAUGHT AND THE

TYPE/CONDITION OF WOOD TO BE BURNT. THIS

MAY TAKE 2 OR 3 DAYS TO ASCERTAIN.

1. If the fuel in the firebox is exhausted prematurely, the overnight chimney draught must be reduced by

5 increasing the opening setting of the flue chamber door, using the flue dilution lever.

2. If the fuel does not burn but ‘dies out’, the draught should be increased by reducing the opening setting of the flue chamber door, using the flue dilution lever.

It maybe necessary to set the thermostat to a higher number to allow more air.

Following overnight banking, the flue chamber door must be closed, the spinwheel and flue chamber damper opened and the fire refuelled.

Immediately the new fuel has caught alight, riddle the fire and close the flue chamber damper to halfway.

NOTE: BUILD-UP OF CREOSOTE DEPOSITS IN THE

FLUE AND CHIMNEY CAN IN TIME, LEAD TO A

CHIMNEY FIRE.

THESE DEPOSITS CAN BE PREVENTED BY THE

REGULAR USE OF A PROPRIETARY BRAND OF

CHEMICAL CREOSOTE REMOVER, WHICH

REDUCES THE ADHESION STRENGTH OF THE

CREOSOTE DEPOSITS.

IMPORTANT: CHEMICAL CLEANERS MUST NOT BE

CONSIDERED AS AN ALTERNATIVE TO CHIMNEY

SWEEPING, ONLY AS SUPPLEMENTARY.

b) Using the cooker boiler for the provision of domestic hot water only, in the summer, a boiler thermostat setting of No. 5 is recommended.

NOTE: TO CONSERVE FUEL, ENSURE THE HOT

WATER CYLINDER AND PIPES ARE LAGGED WITH

INSULATION.

REFUELLING

A correctly fuelled fire will last about 1.5 hours burning wood when maintaining the maximum rated output of the boiler with intermittent cooking periods included.

A deep bed of newly charged fuel on a low fire will take time before heat reaches the ovens, hotplate and boiler.

ONCE RE-FUELLING HAS BEEN COMPLETED,

CLOSE THE FIREBOX DOOR IMMEDIATELY AND

OPEN ONLY FOR RE-FUELLING CHARGES.

DE-ASHING

DE-ASH BEFORE RE-FUELLING. It is useful to remove accumulation of ash from any ledges and the bottomgrate with a poke if necessary.

Open the ashpit door to give access to the ashpan (See

Fig. 9).

In winter, this may be as much as three times daily depending on weather severity.

Cooker usage governs the frequency of re-fuelling.

NOTE: DO NOT ALLOW ASH TO ACCUMULATE IN

THE ASHPAN UNTIL IT TOUCHES THE UNDERSIDE

OF THE BOTTOMGRATE BARS OR THEY WILL

QUICKLY BURN OUT.

Ensure the ashpan is fully home otherwise the ashpit door may not close and lock completely.

Leaving the ashpit door open will cause the fire to ‘run away’ and may cause damage if left unattended.

USE OF THE HOT PLATE

The best results can be obtained by using machined base utensils. The hottest part of the hotplate is immediately above the fire, the other end being for simmering.

The circular plug in the hotplate (near the flue chamber end) is for flue cleaning and must not be removed for cooking.

Keep the hotplate clean with a wire brush.

NOTE: TO OBTAIN OPTIMUM HOTPLATE

PERFORMANCE FOR FAST BOILING OR HOTPLATE

COOKING, FUEL THE FIREBOX TO THE BOTTOM

EDGE OF THE FIREBOX APERTURE TO A

HORIZONTAL LEVEL.

WARNING: THE COOKER TOP PLATE SURFACE

AROUND THE HOTPLATE WILL BECOME HOT

UNDER USE AND CARE MUST BE OBSERVED.

PLEASE REFER TO THE INSTALLATION

INSTRUCTIONS REGARDING MINIMUM

CLEARANCES TO COMBUSTIBLE SURFACES AND

MATERIALS.

USE OF THE TOP ROASTING OVEN

The correct adjustment of the spinwheel and flue chamber damper to obtain the oven temperature required varies with the chimney draught, and can be found only by experiment. The following is a suggested method only, and may need modification to suit local conditions.

Suppose an oven temperature for roasting is desired, and that the cooker is idling.

Thoroughly de-ash the fire as described in the respective paragraph, and re-fuel. Set the flue chamber damper to

No. 3 setting and open the spinwheel as described under

‘COOKER CONTROL’.

As soon as the fire produces flame, close the flue chamber damper. Do not allow the fire to run away.

The temperature of the oven should now rise steadily.

When it reaches a point about 30°C (50°F) below that required, close the spinwheel to approximately one turn open. Thereafter control the temperature of the oven by adjusting the spinwheel.

NOTE: THE METHOD SHOULD PROVE SUCCESSFUL

IN ALMOST ALL CASES, BUT IF CLOSING THE FLUE

CHAMBER DAMPER CAUSES THE FIRE TO SMOKE,

IT SHOULD BE OPENED GRADUALLY UNTIL THE

SMOKING STOPS.

To reduce top heat in the oven adjust the cooker/boiler damper knob gradually away from symbol ‘C’. The oven may be cleaned with a stiff wire brush, when it is very hot.

OVEN TEMPERATURES:-

HOT

220°-260°C (400°-500°F)

MODERATE

150°-200°C (300°-400°F)

SLOW

90°-150°C (200-300°F)

Check with pointer reading on oven door thermometer.

USE OF THE BOTTOM COOKING

OVEN

It is not possible to control this oven, but during the course of roasting, sufficient heat input permits simmering of dishes that have been taken from the roasting oven.

OVEN TEMPERATURES:-

Idling 95°C min.

During cooking - 135°C max.

During the cooker idling periods, the oven is ideal for heating plates and keeping food warm.

FLUEWAY CLEANING

6

Following a prolonged shutdown of the appliance, perhaps after the summer break, ensure the flueway is free from obstruction prior to re-lighting.

The appliance flueways should be checked on a regular four weekly basis, and cleaned if necessary.

Prolonged soot formation may result in flueways becoming blocked and could give rise to the release of carbon monoxide, a poisonous gas into the room.

Failure to ensure clean flueways, flue pipes and bends may lead to emission of dangerous gases and an inferior performance from your appliance.

Cooker Flueway - Allow the fire to burn out, open the flue chamber damper to its maximum and remove the flue chamber door.

Turn the cooker/boiler knob to ‘C’.

Brush the soot or fly ash from the flue pipe allowing it to fall onto the top of the oven. (See Fig. 11).

Remove the hotplate plug and push the deposits forward, into the firebox. (See Figs. 12 & 13).

Boiler Flueway - Set the cooker/boiler damper knob to

‘H’ and remove boiler cleaning cover in top plate adjacent to boiler thermostat control knob.

Lift out exposed boiler cleaning plate and brush near boiler flueways up and down allowing debris to fall into

the fire box. (See Fig. 14).

Clean boiler flue outlet by inserting brush horizontal at right hand of boiler aperture below top plate, allowing debris to fall into firebox.

The flue restrictor plate may need to be removed to enable deposits to be swept out of the bottom of the boiler flueway. If necessary remove side bricks and grate baffles to ease access.

Replace flue chamber door and hotplate plug and riddle the bottomgrate thoroughly to clear the bottomgrate ready for re-lighting.

NOTE: THE APPLIANCE IS DESIGNED AND

INTENDED TO BE UNDER CONTINUOUS FIRING BUT

IF IT IS NOT IN USE ASHPIT AND FLUE CHAMBER

DOORS SHOULD BE LEFT OPEN TO ENSURE FREE

PASSAGE OF AIR THROUGH THE APPLIANCE AND

AVOID CONDENSATION PROBLEMS.

CHIMNEY SWEEPING

As a minimum, sweep 6 monthly and inspect soot box at

1 monthly intervals and remove any deposits.

NOTE: SWEEPS BRUSHES MUST BE OF THE TYPE

WITH WIRE CENTRES AND GUIDE WHEELS.

CLEANING

Surface blemishes caused by spillage on the gloss enamel are easier to remove when the cooker is cool, and a damp cloth is usually all that is necessary.

This should not be done whilst the cooker is hot.

DO NOT USE ABRASIVE PADS, OVEN CLEANER, OR

CLEANERS CONTAINING CITRIC ACID ON

ENAMELLED SURFACES.

IMPORTANT NOTE: AGA recommend Vitreous Enamel

Association approved cleaners for cleaning the vitreous enamelled surfaces of this product.

But they are unsuitable for use on: chrome and stainless steel components, including the hand-rails and their brackets.

The insulating covers should be cleaned regularly with a

NON-ABRASIVE mild detergent, applied with a soft

(coarse free) cloth and lightly polished up afterwards with a soft (coarse free) duster or tissue to bring it back to its original lustre.

TO REPLACE BOTTOMGRATE BARS

Allow fire to burn out first, then open the ashpit door and lift off the clinker door. Remove dead fuel with hooked poker into ashpan and then lift up each individual bar, pulling forward to remove.

NOTE: THERE ARE TWO TYPES OF BARS FITTED

AND THE REPLACEMENT BARS SHOULD BE

CHECKED AGAINST ‘REPLACED’ BAR BEFORE

REPLACEMENT.

FIREBRICK REPLACEMENT

The firebricks fitted to the Rayburn 345W are of first quality manufacture, and providing the cooker has been installed and used correctly will have a reasonable life.

They are, however, expendable items and in time will require renewal.

Replacement bricks either in sets or singly can be obtained from your Rayburn distributor. Always quote the manufacturing number.

The manufacturing number, which will be found fixed to the appliance, should be quoted if any question arises in connection with the Rayburn 345W Cooker.

GRATE PLATE REPLACEMENT

Three plates are supplied with the cooker and are designed to sit on the reciprocating bars with the return edge downwards. In the event that these plates wear out replacements can be obtained. The burning time and output of the appliance will be effected without these plates being in place.

HOT WATER SERVICE

The cooker has been designed to provide a satisfactory supply of domestic hot water with or without a limited amount of heating with a normal day’s cooking providing the cooker is kept alight overnight and the system complete with lagged cylinder conforms to the installation instructions.

SERVICING

Always use a qualified service/heating engineer when servicing is required. Use only authorised replacement parts. Do not make unauthorised modifications.

Any air inlet grilles must be maintained so that they are free from blockage.

Failing to maintain your cooker properly can lead to a chimney fire. Chimney fires occur when combustible deposits on the inner walls of the chimney ignite. These combustible deposits, called “creosote”, are a natural byproduct of wood burning. A fire hazard exists if 1/4” of creosote (or more) coats the inner walls of the chimney.

NOTE: This is the location of the Flue Restrictor Plate.

FUME EMISSION WARNING

Properly installed and operated, this cooker will not emit fumes.

Occasional fumes from de-ashing and re-fuelling may occur but persistent fume emission must not be tolerated.

If fume emission does persist, then the following immediate action should be taken:a) Open doors and windows to ventilate room.

b) Let the fire out or remove lit fuel from cooker.

c) Check for flue or chimney blockage, and clean if required.

d) Do not attempt to relight fire until cause of fumes has been identified, and if necessary, seek professional advice
