1.6 Potential problems and how to tackle them ............................................ 29

ATTENTION! It is necessary to quote the article number and the serial number on the model plate when ordering parts!21

1. The stoves are tested to EN 13240 (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 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.

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. 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).22

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 not23

For kindling please use wood scrapings or grill starter but never use liquid auxiliaries! The first kindling

• At the first fire set-up could be a little smoke, but is not dangerous, normal! In this time, please ventilate the room carefully! Warning! Upon the first kindling, smoke and unpleasant smell may be generated. Always ensure the proper ventilation of the room (by opening windows and doors), and heat the fireplace at maximum rated heating performance. If with the first heating the maximum temperature is not reached, the above-mentioned effects may as well arise later on.

• Before installation pull out the delivery securer off the refractory brick through the furnace chamber (picture no. 5). Open the door by raising the handle (Picture 1). If the equipment is hot, you can use insulated gloves. Adjust the primary air regulator and the fuel switch (Picture 2) according to the Table 2. Put coal lighter or wood wool onto the fire grate, followed by wood chips. First insert small pieces of wood, and then larger ones, light them and close the door again. When the wood burns quickly, and leaves sufficient glowing embers, put additional fuel on the fire. Thereafter, adjust the primary air regulator and the fuel switch according to the Table 2 („Adjustment”). The first kindling should be performed “finely” with little fuel only, so that the parts of the fireplace are adapted to heat. During the first kindling, the generation of smell is normal and absolutely undangerous

1.3 Putting out of operation

• Let the glowing ember burn to ashes and the fire-place get cold.

• Empty the furnace chamber and the ash bin.

• Close the doors, and shut off the primary air regulator and the fuel switch.

1.4 Heating instructions

The fireplace should be operated only with closed furnace chamber door. Fireplaces belonging to type 1 have self-locking furnace chamber doors. These doors may be opened only for kindling, loading or when cleaning the furnace chamber (otherwise draught problems may occur with other equipment connected to the same chimney). Warning! When opening the furnace chamber door, any incorrect handling or insufficient draught may induce smoke. Always ensure that the furnace chamber door may be opened only slowly, first just to a small extent, and then fully after a few seconds. In addition, if you intend to put additional fuel into the fire, before the opening of the door only there may be only ember bed in the burning space, i.e. no flames may be visible. Led into the burning space in correspondence with the existing conditions, the secondary air provides for the follow-up burning of the combustible components of in the burning space. This in fact means smoke and soot-poor burning, which contributes to the protection of the environment. If you wish to commission the fireplace in a transitional period, please, please first examine the chimney draught, as it can be especially weak at high external temperatures. Towards this end, hold a burning match in the slightly opened feeding door. If the flame is not drawn significantly by the draught, then a so-called starting fire is to be set first. Towards this end, burn wood chips/wool in the fireplace or the cleaning hole of the chimney. The fire grate is to be cleaned before every kindling to ensure the proper inflow of air for burning. The ashtray is to be emptied regularly (Figure 3). Should the equipment be extremely hot, use the gloves provided. Please, be careful not to dispose glowing materials into the waste bin. Ensure that the ashtray should be fully pushed into the equipment. Warning! In order to keep the air clean and safeguard the fireplace, do not exceed the specified maximum fuel quantity; otherwise overheating may occur, which potentially damage the equipment. Such damage is not covered with any guarantee. Only a single layer of fuel is allowable to be prepared in the fireplace. Try to reach lower heating performance only by decreasing the quantity of fuel, and not by cutting the primary air supply.27

1.5 Cleaning and maintenance

After the heating season, it is recommended to clean the fireplace and the flue gas pipes carefully. Any dropping heating performance is almost always the consequence of the strong contamination of the flues. For cleaning, the baffle plate (Picture 5+6) is to be pulled forward. This way, the flues can be cleaned from the inside or – after removing the flue gas pipe – from above. After cleaning, the baffle plate (Picture 5+6) is be pushed back fully again. Warning! Following every heating season you are advised to examine the fireplace thoroughly. If any repair or reconditioning is needed, please, contact your local dealer in a timely manner, and specify the model number and serial number of your equipment (as seen on the model plate). External surfaces may be maintained only after the fireplace cooled down, and following the first commissioning. Use cold water for cleaning, or soap, washing ingredient in extraordinary cases, then wipe it dry. 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, spread it, and wash it down with a wet cloth, followed by drying with a clean, soft cloth. In case there are sticky fuel deposits on these surfaces, first scale simply them with a ceramic-plate scraper held in flat angle, and then clean the surfaces as described above. Cleaning of the ceramic surfaces dirt and grease are to be removed with soap and water. Cleaning of the soapstone and sandstone: the soapstone is a natural stone, therefore minor colour differences may occur; as it is normal, they may not serve as a basis for quality complaints! To clean the soapstone from dirt and fat with water and soap, as well as small scratches, use sand paper (grain size 240).

Warning: Under no circumstances you may use sponge, scouring, aggressive or

scratching cleaning agents! If the grate is blocked so that the equipment cannot serve the intended function, the grate is to be removed for cleaning.28

1.6 Potential problems and how to tackle them

Kind of operating problem Possible reasons Solution Odour formation Curing of the applied preventive lacquer. Steaming oil remains. Operate the fire-place on a low heating level according to the instructions manual for a few hours. Then heat up for maximal performance for a few hours. Too little heating performance

• We chose too little performance

• Chimney draught is slight

• Have the heating requirement of the room examined by an expert

• Chimney draught shall be at least 12 Pa, short max. 18 Pa.

• Check the tightness of your chimney and also that the doors of other fire-places leading to the same chimney are closed and sealed properly. Make sure that the chimney-cleaning joints are sealed properly.

• Too long and leaky smoke tube

• All the smoke tube joints must be well sealed and fireproof-isolated

• Leakage at the door glass

• Check the sealing, close the door properly. May have to have the tightening flap renewed.

• Use well dried wood only.

Actions to be in chimney fireChimney fire may occur upon the improper cleaning of the chimney, the use of inappropriate fuels (e.g. excessively wet wood) or the inadequate setting of the burning air. In such cases, close the burning air at the fire, and call the fire service. Never try to extinguish the fire with water!30

For setting purposes and connection to the chimney, the fire protection requirements as prescribed in the given locations, as well as standards DIN 4705, DIN 18896, DIN 18160, EN 13384, EN 1856-2 and EN 15287 should be complied with. For the problem-free functioning of the equipment, the chimney that the fireplace is to be connected to has to be in perfect conditions (mainly Germany).

2.2 Place of installation

As the air needed for burning is drawn from the room where the fireplace is located, ensure that sufficient air supply is received via the gaps by the windows and external doors. Make sure that 4 m

of air should be provided to each kW of rated performance. For this fireplace, it means that the room has to be at least 32 m in volume. If the room is smaller, sufficient air supply can be secured by opening air connections to other rooms with air openings (at least 150 cm

All the combustible materials, furniture or e.g. decoration materials that are in the close environment of the fireplace should be protected from the heat. Furnishing in the radiation area Keep a minimal distance of 100 cm (A) between the front edge of the fireplace and the combustible equipment, furniture or e.g. decoration materials in the building. The security distance can be reduced to 50 cm (B) if a heat shield is placed in front of the object to be protected (see example in Picture 7). Furnishing beyond the radiation area The walls beside and behind the fireplace may not be made of combustible materials, and they cannot be covered with such materials if the distance on the sides is under 50 cm, or 50 cm on the rear side. Similarly, the distance to wooden and plastic furniture on the sides should be at least 50 cm (see Picture 8).31

pic. 7 pic. 8 Floor in front of and under the fireplace Floors made from combustible materials, such as carpets, parquet floors or cork is to be protected by a shield of non-combustible material – for example ceramics, stone, glass or steel – placed under the fireplace so that it should reach out to 50 cm in front and 30 cm besides.

2.4 Connection of the fireplace

Before connecting the fireplace to the chimney, seek advice from the competent chimney sweeper! The connecting elements should be attached to the equipment and to each other in a properly sealed and stable manner. They may not hang into the unobstructed cross- section of the chimney. The interconnecting piece between the chimney and the fireplace should be of the same cross-section size as the pipe stub of the fireplace. Horizontal connecting pieces should ascend to the chimney in 10°. Pipes that are not heat-protected or not led vertically may not be longer than 1 m. There should be a minimum distance of 50 cm kept between the connection pieces of the fireplace and combustible materials in the building. Provided that the interconnecting pieces have a non-combustible coating of minimum 2 cm, the distance from combustible materials may be at least 10 cm. If the interconnecting pieces are led through equipment or furnishing made from combustible materials, they have to be covered with a protecting tube made from any non-combustible material in a distance of at least 20 cm, or they have to be coated with any non-combustible material with low heat conductance in a minimum range of 20 cm.32 Smaller distances to combustible materials are permissible if it is ensured that at the rated performance of the fireplace the temperature cannot rise over 85°C at the combustible equipment and furnishings.

The connection of the fireplace to the chimney is not permissible if the effective height of the chimney is less than 4 m, or 5 m with multiple loading (see the details of chimney calculations on 3.). To the chimney that the fireplace uses, a maximum of two other fireplaces, ovens may be connected.

How to connect the Ø 120 mm rear pipe:

1. Remove the top flue pipe stub and the backside cover plate.

2. Mount the rear closing cap of the flue opening tightly on the top.

3. Place the supplied coating plate (see ash-box) on it.

4. Tightly screw the flue pipe stub on the backside.

The fireplace can usually be connected to the chimney with an angle pipe With weak chimney draught, the fireplace is to be connected to the chimney through a vertical flue gas pipe facilitating discharge.33
