1. Fire Plus System

The Fire Plus System of your FIREPLACE provides optimal, environmentally friendly burning and - combined with an effective heat exchange system - high efficiency.

After loading and lighting the fuel, the first phase of the combustion process starts by proceeding to burn the gases leaving the fuel. This is the time of, "high flames". After the flames reduce, the rest of the coal burns up in the second phase of the combustion process. This process is characterized by strongly glowing embers with no or only smaller, temporary flames. Optimal and environmental friendly burning with high efficiency can only be achieved if we provide the necessary quantity of air at the appropriate places in all phases of the combustion process. Both the longer time spent in the combustion chamber by gases mixed with air and the hot combustion chamber have a positive effect on the combustion process.

This effective burning can be achieved by the Fire Plus System. The primary air flow through the openings of the grate is completed by the secondary air flow through the glass front and tertiary air entering at different heights of the combustion chamber.

Wood, wooden briquettes and brown coal briquettes are fuels of "high flame". At this height and later above the glowing embers secondary and tertiary air get inside in such way that mixing of the air and gases and the time that gases spend in the combustion chamber (depending on their structure) results in good burning. The excellent quality lining (chamotte, vermiculite) of the combustion chamber, provides high temperature, helping the process. After, that gases are lead through one or more dead-plates in the upper part of the stove, namely through a heat exchange system, that consist of a pipe system where heat is transmitted again. Gases finally leave the stove through the flue outlet and then enter the chimney at a temperature of 230-300°C through the connecting pipe. The remaining energy content of the gases provides the necessary feed pressure in the chimney, "motor of the stove". This is the operating principle of FIREPLACE stoves.

Fireplaces are structurally not suitable for non-stop use.. Only a relatively small amount of fuel can be loaded in the combustion chamber at any time. More information about quantities of fuels loadable for one occasion is given on the attached technical data sheet.

2. Heating capacity

The heating capacity according to DIN 18893 standard is in m3, referring to buildings that do not comply with the Heat Insulation Regulation. For buildings complying with the mentioned regulation other values are valid (DIN 18893-1). Make inquires about further details at a specialized dealer or a responsible chimney sweep.

Back to the top.

 

3. Installation guide

All national, regional and local laws, orders and regulations must be taken into consideration.

This might mean that depending on the location, installation may have to be done by an expert, a specialist company and additional fire fighting measures need to be taken into consideration. Regarding this matter, ask a responsible chimney sweep or other competent expert before installing and operating the appliance. (You can also get help from DIN 18896: 2005-06 standard that contains the technical rules of installation of solid fuel stoves and the requirements of their users' instructions.)

Examination of chimneys takes place according to DIN EN 13384 standard. The necessary data for examination and the safety distances from combustible and heat sensitive materials are contained in the attached technical data sheet.

Attention!

The necessary feed pressure for chimney examination given on the technical data sheet is the necessary minimum value at the flue outlet of the stove. This is necessary for safe operation of the stove. Practice shows that higher, sometimes too high feed pressure exists in chimneys. Such high feed pressure (more than 20 Pa) can lead to uncontrollable combustion process that can damage the appliance itself, the connecting pipe and the chimney as well. If this problem exists in your chimney, please consult a chimney sweep or a competent expert about finding a solution.

In such cases, we recommend the use of a feed pressure regulator (flow control valve in the flue or providing secondary air inside the chimney). FIREPLACE stoves comply with DIN 18891 (building category 1) and DIN EN 13240 standards. These fireplaces are fitted with automatically closing doors so they can be connected to chimneys serving another stove as well, in case the chimney is suitable otherwise (excluding chimneys built and used for gas and oil heating).

Fireplace stoves are freestanding fireplaces that cannot be equipped with an individual cover or be built in as a fire chamber insert/cassette. You must not make any modifications influencing the operation of the stove. Remove all packaging and supporting materials from the fire chamber and all accessories from the ash drawer and the wood case. Make sure that the lining of the fire chamber and all pieces of the dead plates are in the right place. Don't use the fireplace without these components. Take care as the packaging material can contain nails and other pointy, sharp pieces of metal. Causing danger of injury! Take special care that the nylon and other wrapping materials do not get into children's hands. They may cause suffocation! Carefully collect the packing materials mentioned above, keep them away from children and take them to the local waste disposal site. The fireplace is painted with high quality heat resistant lacquer that gains its final stability when heating up for the first time. The smell at the first heating up derives from the evaporation of the protecting lacquer in the paint. So the heated room must be carefully ventilated from time to time (every 1-2 hours). This will stop later on.

Do not put anything on the fireplace before the first heating up and don't touch its surface to prevent damage of lacquering. Use protective gloves for your own protection and for the sake of intactness of lacquering. The doors of the fireplace should be kept slightly open during the first heating up so the insulation cord doesn't stick to the front of the fireplace

4. Pay attention to the following before and during installation

In the first step, the location and the way of connection of the purchased appliance has to be chosen with consideration of the safety instructions.

The chimney must be suitable for operating the fireplace.

Installation and usage of fireplaces must be reported to a competent chimney sweep or another competent expert. Applying the local regulations a chimney sweep/competent expert has to issue a written authorization to use the stove. Make sure you get a record of the receipt.

Examination of the chimney happens according to the local rules which are usually national or European standards.

The local rules should be taken into consideration during the installation of the connecting pipe as well. These are usually national or European standards. Necessary air supply for proper burning has to be ensured. In hermetically insulated rooms a separate air inlet pipe is needed to guarantee a sufficient supply of air for the operation of the fireplace. It is also necessary in the case of rooms with forced aeration system (e.g. an extractor fan) If it is possible, a solution must be found for turning off these appliances. Some FIREPLACE stoves have an optional connection for an outside air inlet.

Use of fireplace stoves in buildings with hermetic insulation and mechanical airing systems is only allowed under certain conditions. Authorization of the stove as "independent of the air in the room" and insulated air inlet from outside are among these conditions. It is important to consult a competent chimney sweep / expert regarding this matter. Choose a location for the fireplace close to the chimney to prevent the use of a long horizontal connecting pipe. The location of installation has to be flat and level. Make sure that the floor has the necessary load-bearing capacity. The weight of the appliance can be found on the attached technical data sheet. In case the load-bearing capacity of the floor is too low, usage of a plate for better load distribution might help. If the problem exists you should seek professional help.

5. Minimum distances from combustible or heat sensitive materials

The technical data sheet and the type board on the stove contain the data referring to the stove that might differ from these standard regulations.

In case of combustible floors, being sensitive to a rise in temperature, non-combustible floor protector must be used. This floor protector must reach 50 cm beyond the front (from the charcoal pan), 30 cm beyond the side (from the inner wall of the combustion chamber) of the fireplace. The floor protector can be made of metal or glass which can be chosen from the product list of FIREPLACE accessories.

The given minimum safety distances from combustible or heat sensitive materials have to be kept by all means at the back, the front and sideways. 100 cm 20 cm 30 cm 20 cm 50 cm 20 cm 50 cm In case a fireplace stove can be installed without safety distances that can be found on the technical data sheet and the type board. More information about safety distances from the connecting pipe can be found at the description of connecting.

Back to the top.

 

6. Preparing the appliance for connection

Let's choose the way of connection (top or rear). Diameter of flue outlet is 150 mm. Appliances are sold equipped with a top outlet. We recommend this connection mode because of combustion technological reasons. In case you would like to connect the stove at the back (technical data sheet contains the connection height), remove the flue outlet from the top and the closing lid from the back. Put the flue at the back, and close the top outlet with the closing lid. Carefully insulate the outlets.

Readjusting the flue outlet from the back to the top: Remove the flue outlet from the back and the closing lid from the top. Put the flue outlet on the top and the closing lid on the rear outlet.

Cover the rear outlet with a heat protecting plate as well.

Carefully insulate the outlets.

In case of top connection:

The height of connection can be chosen without any restriction but it cannot exceed 1 meter above the upper edge of the stove. The horizontal part of the connecting pipe must be at least 40 cm from the ceiling. Be certain that there is a hermetically closable cleaning slot at the elbow of the vertical and horizontal connecting pipes. In case of stoves with a capacity of 6kW the minimum length of the vertical connecting pipe is 50 cm.

Back to the top.

 

7. Connecting to the chimney

We recommend the use of an insert with a double wall for connecting to the chimney. The insert has to be installed into the chimney. Then you can connect the connecting pipe of the stove to it. All combustible materials have to be removed within a 20 cm radius of the insert and have to be replaced by heat resistant/non-combustible material. Install the insert carefully and insulate. If there is wallpaper it is recommended to remove from behind the stove and in case of a corner model from the side as well. 

For fixing the ceramic or soapstone tiles of FIREPLACE stoves with ceramic or soapstone cover, please read the appropriate section of the users' manual. (Instructions for fixing the elements of stoves with ceramic or soapstone tiles.) Installation of the connecting pipe: connect the pipe to the flue outlet of the FIREPLACE appliance. Push the fireplace stove to the chosen location with consideration of the specified safety distances and install it in such way that the connecting pipe fits into the prepared chimney insert. The safety distance from combustible or heat sensitive materials is contained in the attached technical data sheet.

Attention!

All connections must be exact and insulated. The connecting pipe must not reach the free surface of the chimney. Connections are recommended to be sealed with heat resistant glue.

Warning, before using your new FIREPLACE for the first time, please refer to the users' manual.

Back to the top.

 

8. Instructions for fixing the elements of stoves with ceramic or soapstone tiles

Most FIREPLACE models are completely assembled and they only need to be professionally connected to the chimney. Some models are packed as a kit that needs assembling. Take into consideration the separately attached assembling guide with these models.

If by any reason it becomes necessary to remove and refit the quality cover (ceramic, soapstone) of the assembled models, please contact us by phone or mail, or have it done by a professional.

In both cases, we can send you an additional user's instruction manual for removing and refitting the cover.

Before connecting the stove, please take off all accessories that are not attached, such as top soapstone/ceramic tile or the soapstone /ceramic tiles placed in the warming plate. This way you can prevent these parts from falling while moving the stove.

9. Handling guide

Attention!

All national, regional, local laws, orders and regulations must be kept.

Therefore, depending on the location of installation, special operating conditions and restrictions can be enforced regarding the period of use and fuels used. It is important to consult a chimney sweep or other competent expert before installing and using the appliance.

Back to the top.

 

10. Suitable fuels

Use the following fuels only:

Dry wooden log (beech, oak,...)

Wooden briquette

Brown coal briquette

You can find the exact information on the technical data sheet and the type board. You can only use these specific fuels. Usage of other fuels is not allowed. Depending on your choice of the fuels listed above, be sure that you use fuels of good quality. Wooden logs reach 15-20% humidity which is the most appropriate for heating if they are stored outside for 1to 2 years (if they are covered and protected from rain). Recently cut wood has a high moisture content and burns poorly and causes soot. Apart from its very low heating value it is also a pollutant to the environment. High condensation and tar can lead to blockage in the stove and especially in the chimney. In all cases it causes deposit on the glass front and emissions that need to be avoided. Burning wood is recommended for operating the stove at its nominal capacity. Watch the heating value of the fuel you use. You can get the exact data at a fuel supplier. Load the fireplace with fuel according to heat demand. The heating value of 1 kg of dry wood is 4 - 4,5 kW/h. So you can place about 2,5 kg of wood into a stove of 8 kW capacity every hour. When burning wood, if you would like to reach a lower capacity, do not restrain the fire. Put less wood in at one time instead. Don't throw the fuel in the combustion chamber, because it can damage or break the chamotte or vermiculite tiles. Be aware that the volume of some types of wooden briquettes increases during burning. Choose the wooden briquette that has the appropriate size to the measurements of the combustion chamber and does not increase in size while burning. You can use brown coal briquette for burning at nominal capacity just as wood or wooden briquette. Apart from that, it is also excellent for keeping the embers glowing during the night (about 10 hours). In the case of brown coal briquettes, wait until the fuel is completely burned through and close the primary air regulator to keep the embers burning only after that. The types of fuels that can be used, the maximum quantities that can be loaded at one time and the description of settings for the air regulators, can be found in the attached technical chart.

Back to the top.

 

11. Reducing emissions

You can only avoid unwanted emissions by the use of the specified fuels. Put only the amount of fuel in the fireplace that is appropriate for necessary heat transmission. Burning more fuel is unnecessary and leads to unwanted emissions. Don't burn waste in the stove! The use of other fuels than the ones listed above is not allowed. You MUST NOT burn the following materials in the fireplace:

Wet or treated wood,

Wood-shavings, sawdust,

Inner bark, bark, shavings panel,

Coal dust,

Waste, scrap, plastic, rubble

Paper and cardboard (apart from lighting the fire)

Back to the top.

 

12. Lighting the fire for the first time

Follow the directions below when you light the fire for the first time.

High burning temperature is necessary for the fuel to catch fire quickly, so put enough fire-starter on the grate at the lower part of the combustion chamber. Put 2 or 3 smaller pieces of wood or a similar quantity of wooden briquettes, or 3 to 4 pieces of brown coal briquettes on the grate. (See Picture A)

After lighting the fire, shut the door leaving it ajar (only leave the door ajar, do not close it, when you light the fire for the first time, after the first time you will shut the door completely) and completely open all air regulators. After the wood or briquette has caught fire you can reduce the amount of air flowing in. (Settings of nominal capacity can be found in the technical chart.)

Back to the top.

 

13. Further use

If you have already used the stove, remove the ash from the combustion chamber before lighting another fire. Always empty the ash drawer before each use, while the unit and the ashes are cold, because a full ash drawer can

obstruct air supply

damage the grate

After emptying the ash drawer, replace it immediately. Continue the lighting procedure according to the section "Lighting the fire for the first time". Load more fuel only if the current fuel is only glowing and flames are not visible any more. When loading more fuel, open the door of the combustion chamber slowly so that the smoke gases cannot flow out through the door. Level the glowing embers. Put the amount of fuel necessary for the desired heating capacity on the embers, leaving an inch of space between each piece. Close the door immediately after loading the fuel and keep it closed during use. Set the air regulators according to the nominal capacity, or in case of brown coal briquettes as desired after it has burned down to embers. Always maintain optimal burning! Repeat the procedure after the fuel has burned down. Never put more fuel in the stove at one time than is specified. (See Technical data sheet) Only one portion of fuel can be burned at the same time. Load more fuel, only the fuel in the unit already, has burned down. Always check that there are not too many glowing embers piling up in the combustion chamber. Do not restrain the fire, load less fuel instead, and never close the primary air regulator completely. Your stove is equipped with an automatically closing door. It can be operated only with a closed door. Open the door only if you want to load more fuel and only if the previous amount has burned down to embers. Remember that the stove heats up during use. Keep children and disabled people away from the appliance while operating. Maintain the settings of the air that is necessary for the burning capacity of the stove and keep in mind that the settings of the air depend considerably on the actual chimney draught. Set the amount of air according to your experience. Bad air settings can lead to blackening of the glass front or damage to the appliance, the connecting pipe and the chimney. The lining of the combustion chamber (chamotte or vermiculite) can turn black when you light the fire. This blackening disappears when the stove reaches its operating temperature. Always empty the ash drawer before each use, while the unit and the ashes are cold, because a full ash drawer can

obstruct air supply

damage the grate

After emptying the ash drawer, replace it immediately. Always store the ash in a fire-proof container. Do not put the container close to combustible materials or place it on a combustible surface. Use a protective plate if necessary. Pour the ash into a waste receptacle only after you make sure that it has completely cooled down. The condition of proper operation of the fireplace is the appropriate chimney draught (feed pressure). This is considerably dependent on the temperature of the outer environment. In case of a higher outer temperature (above 15°C) feed pressure can considerably fall and it can disturb proper operation. Do not use the appliance in such cases.

Attention! Combustible remains are deposited in the appliance, the connecting pipe and the chimney during use. This happens increasingly if you use wet or treated wood or fuel that is not allowed. The possible overload of the stove or restrain of the fire can contribute to this also. It is rare that the deposits catch fire due to the lack of regular cleaning. However, this can be noticed from the black smoke flowing out of the chimney, the rise of the temperature of the chimney wall and the increased draught that can result in a whistling sound.

In case of such a fire in the chimney, call the fire-fighters and close all air regulators and outlets. Inform the chimney sweep. Do not spray or pour water in the chimney in any case because it can lead to gas explosion. Remove all combustible, heat sensitive materials from the environment of the chimney, even in the attic.

14. Trouble Shooting

The condition of proper operation of the fireplace is the appropriate chimney draught (feed pressure). This is considerably dependent on the temperature of the outer environment. In case of higher outer temperature (above 15oC) feed pressure can considerably fall and it can disturb proper operation.

What can you do?

Open the primary air regulator a bit more, and fully open the secondary air regulator.

Use only a small amount of fuel at first.

Use only a small amount of fuel when reloading.

Shake off the ash more often. Do not restrain the fire.

Burn through the brown coal briquettes very well and close the primary air regulator for keeping embers glowing only after that.

As a last resort, do not use the stove in a transition period.

What are the causes?

...there is no proper draught at heating up?

Chimney or stove pipe is not closed properly.

Measurements of the chimney are not appropriate.

The door of the stove/supplementary air regulator or the door of another stove connected to the same chimney is open.

...the space is not heating up?

Is the appliance disproportionately small?

Is there too much ash in the combustion chamber?

Is the smoke outlet blocked?

Is the air regulator closed?

...the fireplace gives off too much heat?

Is the air regulator opened too far?

Is the chimney draught (feed pressure) too high?

Did you load too much fuel at once?

...there is scarification, the grate is damaged?

The fireplace has been overloaded.

You didn't empty the ash drawer in time.

Chimney draught (feed pressure) is too high.

15. Special notes

Your guarantee expires immediately in case of extreme or long-lasting overload above nominal capacity or the use of fuel not specified.

Always keep the ash in a fire-proof container. Do not put the container close to combustible materials or place it on a combustible surface. Use a protective plate if necessary. Pour the ash into a waste receptacle only after you make sure that it has completely cooled down. Caution!

Surfaces are hot. When you operate the appliance wear gloves and use the operating handles of the stove. The glass is hot. Keep children away.

Never use spirits, petrol or any other flammable and explosive substance for lighting the fire.

Don't place combustible objects inside the radiation area of the fireplace, within 100 cm from the door of the combustion chamber. Follow the instructions in the section entitled "Minimum safety distances".
