You have made a good choice. Because this product guarantees you: High Quality thanks to use of top quality, proven materials Safe Running thanks to mature technology which has been tested for strict adherence to German and European standards Long Life thanks to durable construction methods. This solid fuel stove provides you with a contemporary compact unit to provide your Cooking Baking and Roasting Heating These stoves save energy, are environmentally friendly and really simple to use. You will find everything you need to know as well as some useful hints in this manual. Please note that the stove must only be installed by a qualified professional, who will also be available to help you should you have any problems at a later date.

Please see the heading “Fuel / Settings” for instructions on the maximum quantity of fuel and details of the maximum chimney draught (18 Pa). If you put in too much fuel and/or the draught from the chimney is too strong, there is a risk of overheating, which can damage the stove and/or the oven thermometer. The oven thermometer goes up to a temperature of 350°C max. The stove can only be used when the fuel door (fire door) is shut. This door must only be opened when lighting, topping up fuel or cleaning the fire box. Any damage to the stove or the thermometer which has obviously been caused by overheating is not covered by the guarantee.

5 Disposal of the device after wear ...................................................... 4730

1. The stoves are tested to DIN EN 12815 (see identification plate).

2. For installation and for flue gas connections, the requirements of the Fire

Regulations (FeuVO in Germany) apply, as well as local building regulations such as the following technical standards DIN 4705, DIN EN 13384, DIN 18160, DIN EN 1856-2 and DIN EN 15287. In order for the stove to function correctly the chimney to which you want to connect the stove must be in good condition.

3. Before first use and before connecting to the chimney, you must read the

Instructions for Use carefully and inform the local authority responsible for approving heating systems.

4. While installing the stove you are recommended to wear clean cotton gloves, in

order to avoid leaving fingerprints which can be difficult to remove afterwards.

5. In the interests both of clean air, and of the safe functioning of the stove, the fuel

quantities listed in the Instructions for Use should never be exceeded, and the doors of the stove must be shut during use to avoid the risk of overheating, which can lead to damage to the stove. Damage due to this cause is not covered by the guarantee.

6. The stove doors must remain shut at all times while the stove is in use.

7. Permitted fuels are:

- Natural chopped firewood (up to 33 cm max. in length) - Lignite (brown coal) briquettes (see permitted fuels in the Instructions for Use)

8. Never use liquid fire starters. Use either special firelighters or wood shavings.

9. Burning rubbish, fine chips, bark, coal slack, chips from planing, damp wood or

wood treated with preservative, paper, cardboard or similar is not permitted.

10. The first time the stove is heated there may be some smoke and an unpleasant

smell. Make sure that the room is well ventilated (open windows and doors) and heat for at least an hour at the maximum nominal heat load. If the maximum temperature is not reached the first time the stove is heated, then there may be further unpleasant smells at a later date.

11. All controls and settings must be used as indicated in the Instructions for Use.

When the stove is hot, please handle only using the implements or protective gloves provided.

12. If the stove is not working correctly, or if the chimney is not drawing properly,

smoke may appear when the fire door is opened. It is very important to only open the fire door slowly, initially just a crack, then wait a few seconds before opening fully. In addition, before opening the fire door to top up the fuel, make sure that only glowing material is present: there must not be any visible flames.

13. Do not place any flammable items in the warming drawer or on the surface of the

14. When in use, all surfaces and particularly the glass doors and handles and other

controls can become very hot. Make children, young people, older people and animals aware of this danger, and keep them away from this source of heat when the stove is being used. Use the protective gloves or the implements provided.31 Children and young people under 16 must not use the stove unless supervised by an adult who is responsible for them.

15. Make sure that the ash pan is always fully pushed in, until it touches the back.

Never remove ashes while still hot (fire risk).

16. In spring and autumn the chimney may no longer draw correctly, so that gases

produced by combustion are not completely removed. The fire chamber should then be filled with a small quantity of fuel, ideally with wood shavings, and lit under supervision, in order to stabilise the chimney draught. The grate must be clean.

17. After each prolonged period of use for heating, have the stove checked by a

professional. The flues and pipes for the evacuation of fumes must also be thoroughly cleaned.

18. If repairs or replacements are necessary, please contact your supplier with the

necessary article numbers and serial numbers in good time. Only original WAMSLER replacement parts may be used.

19. Work such as installation, setup, commissioning and services, as well as repairs,

must only be carried out by qualified personnel (heating system or space heating technicians). Intervention by non-qualified persons invalidates the warranty and guarantee.

20. As the solid fuel oven/stove draws the air required for combustion from the

surrounding room, you must ensure that sufficient air can be drawn in through non- sealed windows and outside doors. It can be assumed that is this is provided by a room volume of at least 4 m³ per kW nominal heat capacity. If the volume is less than this, then air vents can be used to provide access to further air in other rooms (min. 150 cm²).

21. You must ensure that the correct safety distance is maintained from all flammable

components and materials – to the side, rear and front. These distances can be found in the Instructions for Use or the identification plate.

22. The fire chamber must not be modified.

23. Connection to a chimney whose functional height is less than 4 m, or if multiple

stoves are installed, 5 m, is not permitted. A maximum of two other fires can be connected to the chimney which is to be connected the stove.

24. If the chimney catches fire immediately close all doors and openings and call the

fire brigade. Do not attempt to extinguish the fire yourself. Afterwards have the chimney thoroughly checked out by a professional.

25. Solid fuels naturally create soot, so it is always possible that the window glass will

become dirty: this does not mean there is a malfunction.32

For installation and for connection of flue, the requirements of the Fire Regulations (FeuVO in Germany) apply, as well as local building regulations such as the following technical standards DIN 18896, DIN 4705, EN 13384, DIN 18160, EN 1856-2 and EN 15287. In order for the stove to function correctly the chimney to which you want to connect the stove must be in good condition.

1.4 Place of installation

The stove draws the air required for burning from the surrounding room. You must ensure that sufficient air can be drawn in through non-sealed windows and outside doors. In addition you must ensure that a room volume/heat capacity ratio of at least 4 m³ per kW nominal heat capacity is available. If the volume is less than this, then air vents can be used to provide access to further air supply in other rooms (connecting vents min. 150 cm²).

A constant supply of oxygen or air is required for the combustion process. Normally the air available in the room where the stove is installed will be sufficient. NOTE: In the room where the stove is installed or in the neighbouring rooms there must not be any air extractors or similar equipment. These could cause considerable operating problems and even represent a risk. Consult the local authority responsible for approving heating systems. NOTE: The room where the stove is to be installed must not have equipment such as extractor hoods, ventilation systems etc. which could mean that that room or neighbouring rooms have reduced air pressure.

Ensure that the walls at the sides and behind the range are not constructed of flammable material and/or clad or coated in flammable material, if they are less than 35 cm K 118 and 40 cm K 128/138 of the side from the combustion chamber, and 25 cm K 118 and 30 cm K 128/138 of the side from the oven. Plastic or wooden furniture or similar must also be kept at a distance of more than 20 cm K118 and 30 cm K 128/138 from the back of the range. No flammable or heat sensitive material should be within 50 cm (80 cm K128 F/K138 F) of the front of the range in its field of radiation. If there is a floor covering or a floor in front of the fire door opening which is flammable or otherwise sensitive to heat then it should be covered with a layer on non-sensitive or flammable building material. The layer must cover an area of 50 cm from the front of the fire door opening and also a minimum of 30 cm either side of it. Wall mounted cupboards over the range must have a minimum clearance of 70 cm from the hob plate of the range.35

1.7 Chimney attachment

The connection for attaching to the chimney must be able to withstand at least 400°C. PLEASE NOTE: Before connecting the stove the local authority responsible for approving heating systems must be consulted! Connection pieces must be firmly connected to the stove and to each other and must not leak. They must not project into the open diameter of the chimney. The connection piece between the stove and the chimney must have the same diameter as the pipe socket on the stove. Horizontal connection pieces of over 0.5 m must rise towards the chimney at an angle of 10 degrees. Any pipes which are not heat insulated or vertical must not be longer than 1 metre. The requirements of the Fire Regulations (FeuVO) apply, as well as local building regulations such as for the chimney standards DIN 4705, DIN EN 13384, DIN 18160 and DIN EN 15287. Connection pieces must be tested to DIN EN 1856-2. Measurement X (distance from flammable construction and other materials) must be as defined by the manufacturer of the connection piece. PLEASE NOTE: Fitting to a chimney with a functional height of less than 4 m, or if several stoves are being fitted, less than 5 m, is not permitted. (See: Data for chimney calculations / Chapter 4.) A maximum of two other fires can be connected to the chimney to be connected to the stove. For safety reasons it is not permitted to use a steam extractor hood to remove air when the stove is producing heat.

1.8 Choice of flue gas connection placement

The flue socket is fixed and located at the rear of the range. If the flue pipe is to be connected on the side or on the top, the back wall connection must be covered with the blind cover removed from the top or the side. In the case of a connection from the top, the cover in the top of the range must be removed and the emission nozzle must be installed. If the flue pipe is to be connected from the side the procedure is as follows: Remove the blind cover on the outside sidewall by removing the bolt. Remove sidewall:

1. Remove the blind cover (pull off forwards)

2. Undo bolts in the sidewall.

Remove the blind cover on the inner sidewall by loosening the bolts and turning the cover. Take the flue connection from the back and mount it on the side. Put the blind cover on the back to replace the flue connection which is now remounted on the side. Tighten bolt. Replace sidewall and blind cover.38

1.9 Connecting flue gas at Ceran plate (only K128 / K128F)

In principle, the devices are manufactured in the version as ordered. Once a device has to be retrofitted or rebuilt, to be carried out subsequent operations (special order): seal plates mounted (no. 1) Mount connecting plate (no. 2) fixed to the bracket with the two wing nuts (no. 3) Fix Ceran plate (no. 4) on the cooker Hang 4 spacers (5 Nr.) on the connecting plate (no. 2) and position the small Ceran plate (Nr. 6). Ceramic hob - Position can be aligned by adjusting the wing nuts as desired.39 2 Fuels / Settings

Low smoke, trouble-free operation of the stove and a supply of heat at the nominal level with a chimney draught of 12 Pa are only guaranteed when you use the following fuels and no others. Only use natural, dry chopped firewood with a remaining humidity of max. 20% and lignite (brown coal) briquettes. Type of fuel Heating value appr. kWh/kg Lignite briquettes Hardwood Softwood 5,3 – 5,5 4,0 – 4,2 4,3 – 4,5

Non-permitted fuels include: Rubbish, fine chips, pellets, bark, chips from planing, coal slack, damp wood or wood treated with preservative, paper, cardboard or similar. For lighting use wood shavings or barbecue lighters. Never use liquid fire starters! PLEASE NOTE: The first time the stove is heated there may be some smoke and an unpleasant smell. Make sure that the room is well ventilated (open windows and doors) and heat for at least an hour at the maximum nominal heat load. If the maximum temperature is not reached the first time the stove is heated, then there may be further unpleasant smells at a later date.

3.1 Important operating components

3.1.1 Adjustable grate

The range is equipped with a height adjustable grate for summer and winter operation. Adjusting the grate for summer operation (K128 / K138) To adjust the grate to the summer operation position, the grate and the grate support should be removed from the range. Then attach the adjustable grate support (included with the accessories) to the front of the upper grate support (see Fig. 7). Insert the grate support with the grate on top.

3.1.2 Performance control

The burning rate and therefore the heating capacity of the range can be regulated by the combustion air intake under the grate. This primary air is set using the primary air regulator (Fig. 6). K118 / K128 / K138 K128F / K138F

1 = Lighting, Lignite (open) 2 = Wood 3 = Not in use (closed)

3.1.3 Secondary air control (without K 128 F / 138 F)

The secondary air regulator is in the top of the fire door and can be set according to the fuel being used, wood (1) or coal (0) (Fig. 8).

The start damper is operated from the front. The hooked end of the lid lifter lever which is supplied should be latched into the operating lever slot (Fig. 9). The start damper is open, if the operating lever is pushed forward as far as it will go (lighting up, cooking). The start damper is closed when the operating lever is pushed back as far as it will go (baking, roasting).41 WARNING Leaving the start damper open when heating, leads to overheating and damage to the range components. Besides which it increases fuel consumption.

The oven door can be removed without using any tools. Take hold of the handle, slightly open and then pull upwards at an angle (Fig. 10). Remounting the oven door is done by inserting the two hinge brackets into the slots and pressing in the lower edge of the door with the knee, at the same time pulling up on the handle.

Open the fire door. First put in fire lighters or wood wool and then lay two or three small pieces of dry wood on top. Then light the fire through the fire door opening. Close the fire door and open the start damper. When the wood is burning well, add a shovel of coal or a few larger pieces of wood. The ash door should be left slightly open for the time being and should only be closed about five minutes after adding the fuel The start damper should now also be closed. The performance control is set according to the type of fuel and the desired heat capacity or may be closed completely for a low setting. Using wood, particularly soft wood, only limited slow burning is possible. Lignite briquettes are particularly suited to slow burning overnight. WARNING In the interests of the environment do not fill the combustion chamber all at once. Feed the fuel onto the fire bed in two or three charges at ten to fifteen minute intervals. Do not use paper to start the fire

3.3 Cooking, roasting and baking

If the oven is only to be used for cooking, then the start damper should be opened. When roasting or baking, close the start damper. In summer the grate Raking down, removing cinders and ashes Before adding fuel, open the ash door and, using the cover lifter, riddle the grate. The ash pan should be emptied every day. Remove all cinders at least every third day. WARNING Do not dispose of glowing cinders in dustbins or outsidemust be in the upper position and in winter in the lower position.

3.4 Care and cleaning

A decrease in the normal heating capacity and occasional smoke are signs of the need for the range to be cleaned. Cleaning the draught system To clean the draught system under the oven the knurled nut on the cleaning cover must be unscrewed and the cover removed. After cleaning the cover needs to be sealed again.42

3.4.1 Care of the enamel parts:

Only wipe down the external surfaces when the stove is cold. Varnished surfaces should only be washed with plain water (do not scrub). Enamel surfaces in special cases can be cleaned with soapsuds or a bit of washing-up liquid and then wiped dry. NOTE: Never use sponges, scouring products or any other chemical or abrasive cleaning products!

The oven should be cleaned when it is just warm, not after long periods but every time it is used.

3.4.3 Care of the steel plate:

The steel sheet parts must be rubbed over with an acid-free sheet steel care product when at blood temperature. Cleaning is then done when the stove is cold. The special steel plates which radiate heat need to be taken care of regularly after each time you cook. After any use which causes dampness or dirt to collect on the plate, you must clean it. The hob plate should be cleaned when it is still lukewarm, which allows any remaining water to evaporate and so prevents rust forming. Take care that you do not use water to clean the stove when it is cold. Expansion joints in the steel hob plate must always be cleaned free of adhesions, to avoid deforming the steel hob plate and the side panels. If necessary the edge of the cover should also be cleaned of any adhesions.

3.4.4 Care of the glass ceramic plate:

Clean the window and/or Ceran plate before first use with a clean damp cloth. Then rub a few drops of a ceramic glass protection product onto the glass / Ceran plate with a paper towel. After wiping this and polishing it dry, the high quality surface is now covered with an invisible film. The helps to keep the glass pane /Ceran plate clean and if repeated regularly, makes it easy to clean.

3.4.5 Care of glass (window):

Before its first use, clean the ROBAX inspection glass with a wet and clean cloth, and then put a few drops of glass–ceramics cleaner onto both sides of the glass, and spread them with the use of kitchen paper tissues. It provides an invisible film on the valuable surface of the Robax glass. This film helps to keep the glass clean, and facilitates regular cleaning operations. ROBAX S for slightly contaminated surfaces – a commercially available glass surface cleaning agent – may as well be used for the cleaning of the medium or strongly contaminated glass surfaces of the fireplace. Towards this end, spray small quantities of the agent to the cold surfaces, PLEASE NOTE: After every period of heating you should check the stove thoroughly. If repairs or replacements are necessary, please contact your supplier with the necessary article numbers and serial number in good time. Work such as installation, setup, commissioning and servicing, as well as repairs, must only be carried out by qualified personnel (heating system or space heating technicians). Intervention by non-qualified persons invalidates the warranty and guarantee.43

3.5 Trouble shooting

Your range is constructed to the latest technical standards. Nevertheless faults may occur. The reason can be the chimney, the fuel or the emission pipe system. A short period with a smell and smoke when first starting is quite normal. Make sure the room is properly ventilated. Fault Check/Remedy The range smokes when being fired up in summer

in winter Open the ash door for a short time (high outdoor temperature can cause poor draught). Warm up the chimney with wood wool (either in the chimney or in the range). Open the ash door for a short time. Do not use any damp or smoke intensive fuel. Fill the fire chamber slowly and a little at a time. When the range was last cleaned? Range does not burn properly Is the chimney draught too weak? Is the flue connection not sealed properly? Are all cleaning doors on the range and chimney properly closed? Is a fresh air supply ensured from adjoining rooms? (doors and windows should not be absolutely tight) Is the chimney overloaded or not sealed properly? Too low a temperature when cooking and roasting Open the ash door for a short time. Too high a temperature when cooking and roasting Add less fuel. Grate jams when riddling Have the cinders been removed? Is there a nail or something jammed in the grate? Condensation in the range Is the fuel too damp? Action in case of chimney fire! If a chimney is not cleaned often enough, or if the wrong type of fuel is used (e.g. damp wood) or the air flow is maladjusted the chimney may catch fire. In this case close the air supply to the fire chamber and call the fire brigade. Never try to extinguish it yourself using water!

3.6 Spacer connection

If the range is to be incorporated in a fitted kitchen, then the interface between an adjoining floor cupboard made of wood should be fitted with spacer connections available from the factory. This thermal spacer has been tested to EN standards together with the range and complies with the building regulations for fire protection. The spacer connection is either 55 mm or 110 mm wide and should be mounted on the range frame as a unit and can be adjusted in height (Fig. 11).44
