Planning

Where is a suitable chimney or connection option located for the flue pipe?

General information: We recommend you contact your chimney sweep during the initial planning phase in order to clarify the requirements of the chimney as well as those of the fireplace and the flue pipe.

If a connection is already present:
What is the diameter of the chimney connection and how high is it? You will need this information when ordering your stove. If required, your chimney sweep or your stockist would be happy to help you ascertain this information.

If a connection has to be provided: Please note that the installation must comply with the relevant safety and building regulations. Contact your chimney sweep for further information; he/she would be happy to help.

Where should the flue pipe connection on your stove be positioned?

Flue pipe connections can be positioned at the top, rear and side of the stove. Please bear this in mind when planning your stove. This information can be found on the detailed pages for the individual stoves under "Product information".

What is the size of the room you want to heat?

The room heating capacity specification indicates how many square metres can be heated with a particular heat output (in kW). This should provide you with guidance and a decision making aid when purchasing your new stove. RIKA woodburning and pellet stoves heat rooms measuring up to 260 m³ (which corresponds to an approximate floor space of 100 m2), depending on the level of building insulation present.

A room temperature of 15° to 21°C can be generated in a short space of time, as stoves produce heat quicker than all other heating elements and are able to bring comfort and warmth to your home in just half an hour. This effective form of heating even pays for itself in the transition period.

Heating capacity in comparison:


Our tip: Simple and convenient control of your heating system is facilitated by modern RIKA pellet stoves, which can be fitted with a timer or activated by sending an SMS from your mobile (only available in Austria). So when you arrive home it's already at a pleasant temperature.

Where is your stove positioned?

Depending on the model selected the stove can be set up in the corner, on the wall or in a free-standing configuration; this choice can be influenced by where you want to enjoy the view of the fire (e.g. from your couch or dining area) and of course depending on where the connection for the flue pipe is located.

Our tip: It is even possible for some RIKA stoves to be rotated according to requirements. Simply click the "pivotable" symbol on the stove overview page to display all of the models that can be rotated.

What is the quality of the base on which the stove is going to be positioned?

Immaterial whether the stove is going to be set up on a stone, wood or carpeted floor, the patented RIKA glass or steel floor plates with surrounding sealing lip offer suitable protection for the underlying floor surface.

What safety clearances are to be taken into account?

Please note the minimum clearances required when positioning your stove and selecting the relevant RIKA glass or steel floor plate.

To non-combustible items: a > 100 mm b > 400 mm c > 100 mm

To flammable items (such as a wooden floor) and load-bearing, reinforced concrete walls: a > 200 mm b > 800 mm c > 200 mm

Important information: It is imperative you comply with the national regulations as well as locally applicable provisions and requirements.

When is an ambient air-independent stove necessary?

In order to prevent negative pressure being generated during joint operation of a home ventilation system, extractor hood and a woodburning stove, it is advisable to buy an ambient air-independent stove. This is because all stoves require fresh air for both the heating and operating phase, which is supplied externally. This air can either be extracted from the room in which the stove is located, or it can be supplied from outside via a pipe. In these circumstances this is called an ambient air-independent stove.

All RIKA models with a corresponding configuration are designated with the "Ambient air-independent" symbol. You can view all of the ambient air-independent stoves on the woodburning stove or pellet stove overview page.

A couple of options are available for supplying the fresh air: A separate fresh air shaft can be installed in the chimney or a fresh air pipe that extracts air from outside or a well-ventilated cellar can be used. Select the option that is appropriate for your individual situation. The best way to clarify this point is by contacting your stockist.

CO-value (full load)

The CO-value (mg/Nm3) full load measures the carbon monoxide emissions, related to 13% O2 (residual oxygen).

Combi stove

The RIKA combi stove can be fuelled with pellets and with logs – with no need for conversion or changeover, even within a single combustion process.

Stove Selection

What influence does RIKA's combustion technology have on emission values and efficiency?

All RIKA stoves not only satisfy the planned legal requirements in their entirety, but they also produce results that are below the stipulated values. We have spent years working intensively on optimising the combustion technology used by our stoves. This has enabled us to drastically reduce particle and CO emissions. At the same time, the degree of efficiency produced by our stoves has been increased to in excess of 90 %. This means that smaller quantities of wood or pellets are required to achieve the same heating effect! Modern woodburning or pellet stoves from RIKA generate heat in a very environmentally friendly manner and they also enable future environmentally friendly operation without the retrofitting of high-maintenance particulate filters.

How does this work? Thanks to an improved mixture of the combustion gases with oxygen and an optimum distribution of primary and secondary air, a higher degree of efficiency and a lower fuel consumption can be achieved. Our stoves are equipped with the RLS-SYSTEM (simple one-handed operation of the air regulator) or Rikatronic³ technology (fully automatic air regulation). All of our pellet stoves operate in a fully automatic manner.

These systems thereby provide optimum heating efficiency and maximum heat storage in relation to the dimensions of the stove. This is beneficial for both your wallet and the environment!

What role does storage heat play for economic and ecological heating?

Optimum heat storage – another important decision criterion. A stone casing ensures more effective storage than a ceramic or steel casing. If you find it important for a stove to supply heat for some time after the last flame has extinguished, then opt for a stove with long heat retention properties and the largest possible storage mass. The specifications relating to the storage mass of the individual models can be found on the detailed page of the respective stove.

Why does RIKA focus on timeless design?

Trends come and go. We don't want to jump on the bandwagon of any particular style, but are primarily interested in fulfilling your desires and requirements. Therefore when we design our woodburning and pellet stoves we look towards sustainable and timeless aesthetics as well as future-oriented technology. Our stoves integrate harmoniously into any home and lifestyle and come with numerous colour options. This ensures you will get a lot of pleasure from your stove for a long time to come.

What security features do RIKA products have?

All RIKA stoves naturally fulfil all of the relevant safety requirements.

Only high quality materials that ensure a long service life and operational reliability are used in the production of RIKA stoves. Furthermore, RIKA stoves are exclusively manufactured in Austria using state of the art machinery.

The 4 mm high-grade steel combustion chamber is able to withstand the stove temporarily overheating. The doors on all of our woodburning and pellet stoves are manufactured from high quality cast iron, thereby making them warp-free and ensuring long-term tightness.

A special emphasis is also placed on the transparent ceramic glass panel, which is able to withstand temperatures of up to 750 degrees.

Yet another safety aspect: Our stoves are available exclusively through authorised stockists. Reliable advice, experienced planning, professional stove assembly and expert instruction prevent any unpleasant surprises.

How do RIKA viewing panes remain soot-free?

Combustion residues are an inevitable part of the combustion process. The modern technology used by our woodburning and pellet stoves enables the glass panels to remain largely free from soot. This is due to the patented panel air purge which directs preheated combustion air (secondary air) along the inside of the panel, where it produces a protective "air cushion". The flowing air thereby constantly cleans the panel in the stove.

Why do pellet stoves require little maintenance?

RIKA pellet stoves are equipped with a self-cleaning system, which reduces cleaning requirements to a minimum. A pre-programmed hourly cleaning process, during which the supply of pellets is temporarily interrupted, ensures the combustion cavity is blown free of any ash residues by increasing the speed of the flue gas fan.

What effect does the size of the pellet container have on the service life?

RIKA pellet stoves are not only distinguished through their design, but also by the large holding capacity of the pellet tanks. Below is a brief overview of how long the respective stove can burn in continuous operation with a full tank.

  • RIKA room sensor: with cable or wireless, control via week timer and/or thermostat.

Fuels

Is the stove close to a power source?

All RIKA pellet stoves as well as those RIKA woodburning stoves that are equipped with Rikatronic³ technology require an electrical connection that is preferably as close to the stove as possible. The woodburning stoves with Rikatronic³ technology are provided with the "Rikatronic³" symbol in the left column on the detailed page of the stove. Alternatively you can also display all of the stoves that have "Fully automatic air regulation" (= Rikatronic³) on the stove overview page.

Which wood values have which heat values?

Wood from different types of tree exhibit various calorific values. Hardwood or wood from deciduous trees is particularly suitable for use as a fuel. This burns with an even flame and produces long-lasting embers. Coniferous wood is rich in resin and, like all softwood, it burns quickly and tends to generate flying sparks.

What should be taken into consideration when selecting fuel?

The following applies regardless of the wood type: The drier the wood, the cleaner it burns and the more energy it produces. Therefore you should only use wood that has been air-dried for 2 to 3 year and has a maximum residual moisture content of between 14 and 18 %. If the wood is too wet, water vapour condenses. This can cause damage to the stove and result in reduced performance.

With regard to your health you should only use natural, unspoilt wood. Also make sure that pellets (wood briquettes) have been produced from natural, unspoilt timber.

If the incorrect fuel is used, harmful and environmentally hazardous emissions can be produced in addition to various unpleasant odours. Therefore the following should not be placed inside the stove:

  • damp wood (moisture content in excess of 20%)
  • lacquered, laminated or impregnated wood
  • wood that has been treated with preservatives
  • household waste
  • paper briquettes
  • flammable liquids, burning pastes and jelly

Please note that if unauthorised material is used, it shall result in an expiration of your warranty.

What do I have to look out for with wood logs?

Size of split wood:

Logs exceeding ten centimetres in diameter should be split at least once to ensure they burn properly. Ideal dimensions for firewood: 25cm or 33 cm in length; the diameter of the split wood should not exceed 7 cm.

The size, however, also depends on the combustion chamber: Some models can accommodate 50 cm logs and smaller combustion chambers operate more efficiently with 25 cm logs.

Chop the wood in a well-ventilated, preferably sunny location that is protected from the rain. If possible, stack the wood so that there is plenty of clearance between the layers; doing this will enable the air passing through the wood to disperse any escaping moisture. Fresh wood should not be stored in a cellar, as air and the sun are required for the drying process - dry wood, on the other hand, can be stored in a well-ventilated cellar.

Storage of split wood:


Too much firewood results in the stove overheating. An excessive load is exerted on the material and it will cause your stove to produce negative flue gas values.

Too little firewood or logs that are too large will result in the stove not reaching its optimum operating temperature. The flue gas values produced here will also be negative.

The correct quantity of firewood makes all the difference:

For example, at a nominal heat output of 8 kW:

2 logs or 2 wood briquettes (each weighing approx. 1 kg)

For example, at a nominal heat output of 4 kW:

2 logs or 2 x wood briquettes (each weighing approx. 0.5kg)

Optimum quantity of split wood:

Chop the wood in a well-ventilated, preferably sunny location that is protected from the rain. If possible, stack the wood so that there is plenty of clearance between the layers; doing this will enable the air passing through the wood to disperse any escaping moisture. Fresh wood should not be stored in a cellar, as air and the sun are required for the drying process - dry wood, on the other hand, can be stored in a well-ventilated cellar.

What do I have to look out for with pellets?

Up to 100 percent natural, unspoilt residual wood is used for the production of wood pellets. This raw material predominantly comes in the form of wood shavings or sawdust as a quasi waste product from the woodworking industry. Fine-grain wood residues are compressed under high pressure and pelletised, i.e. pressed into a cylindrical shape.

You can gather an impression of the quality of the pellets from their appearance. Generally speaking, good quality pellets exhibit smooth, slightly glossy surfaces that have no longitudinal splits.

Pellets must be transported and stored so that they are kept completely dry. Please make sure that the pellets are located in a dry area of your storage room. Only by doing this can you ensure flawless and efficient combustion.

What should be done with the remaining ashes?

The mineral element of the firewood and pellet (approx. 1%) remains on the floor of the combustion chamber in the form of a combustion residue. As this ash is a natural product, it makes an excellent fertiliser for all of the plants in your garden. The ash should be stored beforehand, however, and "purged" with water.

Where can I buy firewood and pellets?

Firewood:
You can now order firewood online and have it delivered to your door. However, please ensure the wood you are ordering is from a reputable dealer, as there are significant differences in the quality of both pellets and logs. You can also have a look in the regional daily or weekly newspaper for local suppliers (e.g. farmers).

Pellets:
The sale of pellets is based on trust. Therefore you should only buy pellets bearing the "ENplus A1" logo because those are the only pellets which guarantee top quality. Phrasing such as "based on", "equivalent to" or "as per standard" mean that the production of the pellets is not inspected and monitored in accordance with the standard.

Our tip:

Brand name pellet manufacturers ensure a nationwide network of warmth and comfort with more than 2,000 dealers located in Austria, Germany, Switzerland and South Tyrol. The range of pellets provided by these manufacturers has been rigorously tested according to the DIN and ÖNORM standard, which thereby ensures optimal heating performance and compliance with all of the regional standards and quality seal requirements.

Stove Care

What should I pay attention to when taking care of my stove?

RIKA woodburning and pellet stoves have been designed according to state of the art technological knowledge and have been constructed to ensure minimal maintenance requirements and enhanced service lives. However, certain cleaning activities and seal inspections are still required from time to time. The periods between inspection intervals are primarily dependent on the quality of wood you use and how often you use your stove. We recommend you give woodburning stoves a basic clean after each heating procedure. Pellet stoves indicate the necessary service intervals on the display.

Important information: Please make sure the stove has cooled down completely before conducting any maintenance or cleaning work!


A suitable cleaning and care set for stoves with a soapstone or sandstone casing can be requested from RIKA. Simply send an e-mail or contact us on: 0043-7582-686-41.

If you need to conduct any touch-up work, only use the original lacquer which can be purchased from your dealer as an optional accessory.

Please also note that your woodburning or pellet stove is not suitable for storing, warming or drying items. Exceptions to this rule are those models which are equipped with a cooking compartment or hob.

What is the best way to clean glass surfaces?

When cleaning the cold glass surface use a special degreasing, ammonia-based cleaning agent which is available from your stove dealer.
If the panel is still hot, wait until it has cooled down completely.

Never use abrasive cleaners, as these could damage and scratch the glass panel.

What must be considered regarding thermal stone casing?

Please note that the surface of the stone casing element on your woodburning or pellet stove is not suitable for storing, warming or drying items! Make sure that the surface of the stone does not come into any contact with, for example, any acidic liquids, grease, oil, adhesive, wax, resin, etc.
Minor impurities can be removed using clean water and a sponge or some soap solution. Please exercise caution, however, as the surface or the surface structure could become damaged if this process is repeated too frequently.

What should I look out for in soapstone and sandstone stoves?

If you have a soapstone or sandstone stove, please note that the surface of the stone casing element is somewhat sensitive and is not suitable for accommodating metallic or ceramic pots, cans or containers. Exceptions to this rule are those models which are equipped with a cooking compartment or hob. Generally speaking, Finnish and Brazilian soapstone is used for our soapstone stoves, as this is characterised by a particularly high heat storage capacity. Natural stone surfaces have a decisive advantage in comparison to a painted surface. Stains such as grease, paint, soot particles, etc. can be removed easily.

In order to ensure the surface maintains its appearance even after years of use, please observe the following cleaning and care information:


Use P120 sandpaper to remove any minor impurities on the stone, such as black spots or other signs of use, by applying gentle pressure (in the direction of the grain) until the impurity is no longer visible. Then remove the sanding dust by gently brushing the surface with the supplied brush. Then wipe with a damp cloth without applying any pressure. Repeat these procedures depending on the level of contamination.

In the case of sandstone the dust must be removed with the brush and then a vacuum cleaner. If a damp microfibre cloth is used, it can cause the fine dust particles to be deposited in the pores of the stone. By conducting this step you can also remove the last remaining dust particles from the stone.

How do you clean ceramic and steel casings?

The best way to clean the ceramic casing is by using a damp microfibre cloth and a mild cleaning agent (without any abrasive particles!). Never use cold water to clean the casing while the stove is still hot, as the thermal shock it causes could damage the ceramic casing.

The surface of the steel casing is resistant to extreme heat and should only be cleaned using a soft cloth (wet or dry). We recommend using a microfibre cloth.

How can I clean flue pipes, flue gas ducts, convection air openings and combustion chamber?

The flue gas ducts should be thoroughly cleaned at least once a year. When doing this remove the flue pipes. Any soot and dust deposits in the stove and flue pipes can then be brushed away and vacuumed.

Check the seals of the combustion chamber door and the ash tray at the beginning and end of a heating period. If they are damaged or exhibit signs of excessive wear, please ensure they are replaced.

The surface of the steel casing is resistant to extreme heat and should only be cleaned using a soft cloth (wet or dry). We recommend using a microfibre cloth.

The interior of the combustion chamber consists of a special heat-resistant ceramic lining which should only be cleaned with a brush; never use any metal or abrasive objects.

How can I repair damage to the paint?

If you need to conduct any touch-up work, only use the original lacquer which can be purchased from your dealer as an optional accessory. Never clean the lacquer before the initial heating phase under any circumstances!

General

What happens to pellet stoves or woodburning stoves with Rikatronic³ technology in case of a power outage?

Woodburning stoves that are equipped with Rikatronic³ technology are very convenient to use. In the event of a power failure the Rikatronic³ ventilation flap is automatically opened via a mechanical return spring to ensure a safe combustion process. After a brief power outage the Rikatronic³ unit will resume operation automatically. If the power failure is in effect for a prolonged period, the stove must be started up again.

In the case of pellet stoves the previously set operating functions are likewise continued after a brief power failure. If the power failure is in effect for a prolonged period, the stove must be restarted.

Does the pellet stove motor make a noise?

All RIKA pellet stoves have been designed to operate in an extremely quiet manner.

The RIKA Como and Topo pellet stoves are equipped with an innovative, extremely low-noise, non-cyclic (!) drive for the conveyor system. A requirement-specific and continuous supply of pellets is produced, which also significantly reduces the level of operating noise.

Glossary

Ambient air fan (optional)

The ambient air fan (or convection fan) is an optional fan that can be installed in the pellet stove to facilitate more rapid heat distribution. In principle our pellet stoves operate with natural convection heat. However, if the stove is to be operated continuously at a high power level to heat an adjoining room, for example, the subsequent installation of an ambient air fan is recommended to produce a more rapid heat transfer.

Ambient air fan (standard)

The ambient air fan (or convection fan) is installed in the pellet stove to facilitate more rapid heat distribution.

Ambient air-independence

A stove always needs a supply of fresh air for operation. Normally the combustion air for a stove is extracted from the room in which it is installed. In the following circumstances, however, the combustion air should be supplied from outside, meaning the stove is operated in an ambient air-independent manner:

If there is a particularly dense building envelope, thereby resulting in an inadequate exchange of air for the firing process. This is particularly the case in modern, energy-efficient buildings.

If an extractor hood and a stove are to be operated simultaneously - if a controlled, mechanical room ventilation system is present. More information can also be found in our stove adviser.

SPECIAL NOTE: Please note the differenct national regulations conercing ambient air independence. For further information please contact your RIKA dealer.

Article 15a of the B-VG (Federal Constitutional Law)

Inspection in Austria: Article 15a of the B-VG (Federal Constitutional Law) regulates the marketing and inspection of firing systems in Austria.

Austrian Eco-Label

The Austrian Eco-Label is a seal of approval awarded by the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management which characterises environmentally friendly products and services. The following woodburning stoves have received the award: Cult 6 kW, Vitra S 6 kW, X-Back 6 kW, X-Cook 7 kW, Viva 8 kW, Scena 10 kW, Jazz 7 kW, Eco 8 kW, Eco Plus 8 kW, Fox 8 kW. The following pellet stoves have received the award: Revo 9 kW, Rio 8 kW, Visio 8 kW, Premio 8 kW, Memo 9 kW, Como 9 kW, Topo 10 kW

Automatic ash removal

Automatic ash removal with tipping grate extends the cleaning intervals for the combustion cavity

BimSchV

IThe Federal Immission Control Ordinance (BimSchV) has been amended in Germany. New requirements, for example, should limit emissions of particulate matter and enable climate change targets to be achieved. This is also relevant for stoves. These targets can be supported through high quality woodburning and pellet stoves. Inferior appliances will no longer be able to be built or operated after the defined deadlines. Adherence to the limit values is implemented in 2 stages: 1st stage: After the regulation comes into effect CO: 2,000 mg/m³ Dust: 75 mg/m³ 2nd stage: From 1 January 2015 CO: 1,250 mg/m³ Dust: 40 mg/m³ Installations which do not comply with either stage 1 or stage 2 must be retrofitted with filters (or other similar measures) or they must be decommissioned. Stoves that fulfil stage 1 and have been built prior to stage 2 coming into effect, however, fall under the grandfather clause and do not need to be upgraded! All RIKA models fulfil the requirements of the 1st stage and thereby fall under the grandfather clause. A large proportion of models already fulfil the requirements of the 2nd stage.

Capacity

The capacity of the pellet hopper is stated in kilograms.

Capacity of pellet container

Each RIKA pellet stove is equipped with a pellet container, from which the pellets reach the combusion chamber. Depending on the pellet stove, up to 62 kg pellets can be stored in the pellet container.

Ceramic stove top

If you have an integrated ceramic stove top you can use the heat from the fire for cooking and preparing dishes.

CO-value

The CO-value (mg/MJ) measures the carbon monoxide emissions, related to the energy content of the fuel.

Combustion cavity

The pellets are conveyed from the pellet hopper into the combustion cavity. In RIKA stoves, the pellet transport is virtually silent (no intermittent feed noise). RIKA's patented self-cleaning system reduces the need for combustion cavity cleaning to a minimum.

Comfort

Comfort is an important planning criterion. Several factors, including the surface temperature of the surrounding walls, air temperature, humidity and air movement (flow rate) are critical for the perceived level of (thermal) comfort. Natural heat such as that generated by burning wood in a woodburning or pellet stove creates a comfortable and healthy climate in your home.

Condensation

Condensation occurs when the temperature falls below the dew point in the flue gas channels.

Construction

The construction describes the shape of the stove. A small construction depth, for example, is ideally suited for a cramped installation location (e.g. in a corridor).

Construction type

DIN 18891 distinguishes between construction type 1 and construction type 2 stoves. Type 1 appliances possess a self-closing door and should only be operated when the door is closed. Type 2 stoves may be operated when the door is open (e.g. open fireplace).

Construction type 1

According to DIN 18891 stoves must be fitted with a self-closing door if the door opening is greater than 0.05 m². As the multiple use of a chimney is permitted in Germany, construction type 1 stoves are prescribed in order to prevent endangering any person in other residential units that are connected to the chimney. All RIKA models are equipped according to construction type 1.

Continuous wood burning

A continuous wood burning phase is present if a combustion stage (0.45 hours to 1.30 hours) and an ember stage of up to 4 hours is possible.

Convection air

Air is sucked through the stove from below, warms when ascending and emanates from the top as hot air (= convection air). We speak interchangeably of convection air appliances and warm air appliances. An advantageous factor is the natural convection (for all appliances) without a fan: no electricity is required, there are few moving parts that are subject to wear and tear and, above all, there are no noise emissions. As a rule, stoves typically operate with approx. 30 % radiant heat and 70 % convection air.

Convection air openings

Convection heat enters the room via the convection air openings.

Convection heat

Convection heat is caused by air heating up on hot surfaces, e.g. radiators. As warm air is lighter than cold air, this air moves upwards (convection). In order to ensure optimum comfort in the room a sufficiently high proportion of radiant heat is required in addition to the convection air. As a rule, stoves typically operate with 30% radiant heat and 70% convection heat.

Cooking compartment

If you have an integrated cooking compartment you can use the heat of the fire to prepare delicious dishes and casseroles or bake bread - without using any electricity!

Corner stove

The stove is particularly suitable for installation in a corner due to its body shape. Of course, the stove can be positioned against a wall as well.

Deficiency of air

Lack of oxygen can result in inadequate combustion temperatures that will only cause the wood to char. Smouldering residues with a high tar and water content then split off, which results in heavy contamination and sooting of the flues, glass doors, chimney, etc. (smouldering fire)! In this case it partly gives off unburned (yellow) tar vapour and partly (black) carbon vapour. When wood burns incompletely the parts containing cellulose that have only been partially broken down normally produce an unpleasant smell.

Décor

With a wide range of stone and decorative casings available, the design of a RIKA stove can be adapted to suit the customer.

Dew point

The dew point is the flue gas temperature at which the exhaust gases are saturated with water vapour. If the temperature falls below the dew point, it results in condensation forming in the flue gas channels. In order to avoid this the temperature of the flue gases when leaving the chimney should be at least 70-80°C; this requires a flue gas temperature of around 150°C upon entering the chimney (depending on the chimney system). The use of damp wood increases the dew point.

DIN Plus

The strict criteria of the DIN 18891 standard are expanded through enhanced requirements relating to emission protection (e.g. maximum quantities of particulate matter).

Dynamic-Air-Regulation (DAR)

Automatic regulation of the fan speed, depending on the flow rate of additional air.

Efficiency factor

The efficiency factor illustrates the relationship between the quantity of heat emitted and the fuel supplied. E.g.: an efficiency rating of 70 % means that 70 % of the fuel is used to heat the room, while 30 % is lost as flue gas through the chimney. A high efficiency factor reduces fuel costs and protects the environment. The efficiency factor of an open fire is only around 10 %. The current requirement for stoves is an efficiency factor of at least 73 to 78 % (depending on the various country-specific regulations). RIKA woodburning stoves which are equipped with innovative Rikatronic³ technology achieve an efficiency factor of up to 80 %. RIKA pellet stoves now have an efficiency factor of at least 90 %!

Emissions

The release of substances, energy and radiation into the environment from a particular source is referred to as an 'emission'. In fuel technology (combustion) the term 'emission' refers to the discharge of air pollutants, such as sulphur dioxide, nitrogen oxide, carbon dioxide, carbon monoxide, coarse dust, particulate matter or soot. In terms of acoustics it relates to the noise generated from a source object. In terms of thermodynamics emissions are a measure of the energy loss caused by the radiation of long-wave infrared radiation (thermal radiation). Emissions are thereby always related to a specific source, such as an industrial plant, a particular product (e.g. packaging, mineral wool, car), etc. The prevention or minimisation of emissions is the main objective of a sustainable environmental protection policy (end-of-pipe), as it, in contrast to immission control, does not combat the effects of pollution, but rather its cause.

Energy efficiency class

Class for the space heating energy efficiency.

EnEV 6 kW

This stove has also been certificated for the nominal heat output 6 kW.

Exhaust gas temperature

The exhaust gas temperature is the temperature of the hot combustion gases (exhaust gases). It is dependent on the fuel, the type of combustion and the heat generating appliance. In order to achieve a high degree of energy efficiency, the exhaust gas temperature should be as low as possible (construction-dependent).

External air connection

If there is an external air supply, the combustion air for the heating appliance is supplied from outside. This is also known as an external air connection or ambient air-independent operation. Normally the combustion air for a stove is extracted from the room in which it is installed. In the following circumstances, however, the combustion air should be supplied from outside (ambient air-independent manner): - if there is a particularly dense building envelope, resulting in an inadequate exchange of air. This is particularly the case in modern, energy-efficient buildings. - if an extractor hood and a stove are to be operated simultaneously - if a controlled, mechanical room ventilation system is present.

Extremely flat construction

Stove Topo is characterized by its minimal installation depth, which makes the stove suitable for being positioned in narrow housing situation e.g. ini a corridor.

Fireclay

In general linguistic usage all fire-resistant bricks and lining elements are often referred to as fireclay. In technical usage the term fireclay refers to a rock-like, man-made, fire-resistant material with an aluminium oxide content of 10 to 45%. The word Scharmotte (fireclay) was allegedly coined in the 18th Century by Italian porcelain workers in Thuringia (sciarmotti, scarmotti) based on "Schärm" or "Scharm", the Thuringian pronunciation for "Scherben" ("shard").

Flue gas mass flow

Flue gas mass flow is the air mass and the gassed amount of fuel, which are emitted compoundedly through the chimney.

Flue gas temperature

When leaving the chimney the flue gases should have reached a temperature of at least 70–80°C in order to prevent the formation of condensation. This requires a flue gas temperature of around 150°C upon entering the chimney (depending on the chimney system) (see "Dew point").

Fresh air floor connection

Fresh air supply possible across the floor.

Holding compartment

If you have an integrated holding compartment you can use the heat of the fire to keep your dishes and beverages warm.

Holzenergie Schweiz (Wood Energy Switzerland)

Wood Energy Switzerland promotes a sensible, environmentally friendly, modern and efficient use of wood and it awards its quality seal to those stoves which produce particularly low emissions and exhibit a high degree of efficiency. The following woodburning stoves have received the award: Como, Cult, Eco, Eco Plus, Fox, Tara, Impera, Imposa, Induo, Jazz, Memo, Miro, Premio, Rio, Visio, Roco, Kapo, Scena, Topo, Tura, Twist.

Leak air

Leak air passes into the stove's combustion chamber as a result of non-tight components (e.g. defective door seals). Leak air, which enters the heating appliance in the area of the primary air flap, can intensify the combustion process and cause the appliance to overheat if there is a low heat requirement. Leak air around the filling door cools the exhaust gases and reduces efficiency levels. If there is a low heat requirement, this defect may even extinguish the embers.

Lower air

The primary air or lower air is the air flowing in through the ash cavity across the vibrating grate. The primary air requires the stove to be in the heating phase. When the wood burns fresh air is no longer required from below. This flow of air can be regulated by an air intake register. If your stove is equipped with the intelligent RLS air distribution system, the distribution ratio of the primary and secondary air/lower and upper air is determined automatically.

LRV Clean Air Act (CH)

The Clean Air Act (LRV) has been changed in Switzerland. The Swiss Federal Council decided to revise and sharpen up the Clean Air Act (LRV) of 1985. 2 stages were planned in this regard. 1st stage: From 1 January 2008 CO: 1,500 mg/m³ Dust: 100 mg/m³ 2nd stage: From 1 January 2011 CO: 1,500 mg/m³ Dust: 75 mg/m³ All RIKA models already fulfil the requirements of both the 1st and 2nd stage!

Minimum supply pressure

The minimum supply pressure is an important factor for your chimney sweep. You can find the corresponding information in the instructions for your stove.

Multi Air

This RIKA stoves can, depending on the model, pass the heated convection air into 1-2 other rooms.

Munich fuel regulation

Munich's Brennstoffverordnung (Fuel Regulation) imposes requirements now under the 1st Bundesimmissionsschutzverordnung (Federal Immission Control Ordinance), Stage 2. In addition, emissions of nitrogen oxides (Nox) in the flue gas must not exceed a mass concentration of 0.2 g/m³ based on oxygen content by volume of 13 % under standard conditions (273 K, 1013 hPA) and at rated heating output.

Nominal heating capacity

This is the "normal heating capacity" determined according to DIN 18891. The stove is checked and the room heating capacity is determined according to this rating. The nominal heating capacity is particularly crucial for a safe heating procedure and the functionality of the chimney. The combustion of a defined quantity of fuel is necessary to achieve the nominal heating capacity. This quantity of fuel is specified in the instruction manuals provided with RIKA stoves. The actual heating capacity of a stove is determined by the amount of fuel actually applied. The following applies as a "rule of thumb": 1 kg of wood generates a heating capacity of around 3 kW in a stove.

Output (kW)

The output rating in kW (kilowatts) provides information about the heating capacity of the stove. The higher the kW rating, the greater the heating capacity. The output of a firing system is the useful amount of heat emitted in continuous operation per unit of time. Power rating (old): Calorie (cal) kilocalories (1000cal) = 1 kcal = 1 thermal unit TU Power rating (new): Watt (w) = 1 J/s, 1 kW = 3.6MJ/h = 860 kcal.

Panel flushing

The panel flushing system patented by RIKA channels preheated combustion air (secondary air) from above the panel down into the combustion chamber where it creates a protective "air cushion" around the panel. This ensures your panels are kept free from smoke and soot over a prolonged period.

Pellet consumption

Pellet consumption depends on factors such as the insulation of the house, the quality of the pellets and, above all, the functionality of the stove.

Pellet-Stove-Select-O-Mat

Our Pellet-stove-Select-O-Mat helps you to find the RIKA pellet stove that's right for you. You can make your individual choice of different important criteria when purchasing a stove - depending on your personal demands. With just one click you can find out which pellet stoves are right for you.

Pellets

Pellet stoves are heated with this fuel. Pellets are pressed from wood residues. They are produced from natural, untreated wood without the addition of any binding agents. The wood is bound by its natural binding agent LIGNIN. Diameter: approx. 6 mm / length: max. 30 mm / water: < 8 % (by weight) / ashes: < 1 % (by weight) / dust: < 1 % (by weight) / bark: < 5 % / calorific value: 5.1-5.3 kWh/kg / bulk density: 650-700 kg/m3

Permanent heating

Permanent heating is where a suitable fire burns continuously day and night with a continuous air supply, with the temperature only being reduced at night.

Powerstone

The new thermal storage system achieves optimum thermal storage with maximum efficiency.

Price

The prices shown refer to the basic version of the stove. For the final price, including your desired specifications (colour and material) and accessories, please contact your dealer.

Primary air

The primary air or lower air is the air flowing in through the ash cavity across the vibrating grate. The primary air requires the stove to be in the heating phase. When the wood burns fresh air is no longer required from below. This flow of air can be regulated by an air intake register. If your stove is equipped with the intelligent RLS air distribution system, the distribution ratio of the primary and secondary air/lower and upper air is determined automatically.

Pyrolysis phase

The burning of wood can be divided into three phases: Drying, degasification and oxidation. In the first phase the wood is dried by the heat. In the second phase (pyrolysis) a degasification and thermal decomposition of the wood takes place. Wood predominantly consists of volatile components which are released by heat, thereby resulting in the generation of flammable gases such as hydrogen and carbon monoxide. These burn immediately when provided with a sufficient supply of upper air (secondary air). However, these are also accompanied by fire-resistant gases (so-called smouldering gases). Due to their aggressive nature and good heat output these should not end up in the heat exchanger, chimney or the surrounding environment. The wood turns into charcoal during this phase. The temperature increases from 150 to 550 degrees Celsius. During the third phase (oxidation) the combustible gases react with the atmospheric oxygen supply. This occurs at a temperature of approx. 400°C and above. At the same time the gas is also oxidised from the charcoal, whereby energy is released. This leaves the non-combustible components of wood, also known as ash (0.5% -1%, depending on the proportion of bark).

Quiet operating mode

Due to our new, innovative non-pulsing pellet delivery method this stove is extremely quiet. The annoying "click" sounds are completely eliminated by this method.

Radiant heat

In contrast to convection heat (e.g. radiators), radiant heat does not heat the air, it heats the objects in the room. Consequently it causes very little movement of the air (so it won't stir up dust) and does not dry out the air in the room.

Regensburg standards

The Regensburg standards impose more stringent emission limits than the EN standard that is in force across the country. Limit values (based on a volume content of oxygen in the exhaust gas of 13% under standard conditions (273 K, 1013 hPa) and a nominal heat output) Carbon monoxide: 1,500 mg/m³ Dust: 75 mg/m³ All RIKA models fulfill the requirements of the Regensburg standards.

RIKA FIRENET (Accessories)

Mobile control via Internet and wireless home network.

RIKA VOICE

Voice-based control for stoves via RIKA FIRENET.

RLS

The RIKA air distribution system (RLS) allows you to control and optimise the supply and distribution of air in the stove using one simple hand movement.

Room heating capacity

Stoves should never be too large for the area of installation, otherwise this could result in the viewing panel steaming up and all smoke-conveying components becoming contaminated through condensing flue gases. The room heating capacity of a stove is specified in 3 different sizes pursuant to DIN 18893. These details are fundamentally based on the properties of the room in which the stove is going to be set up: - The most favourable heating conditions are generated by south-facing rooms that have just one outer wall. - Less favourable heating conditions are generated by rooms that have just one outer wall, but unheated adjacent rooms. - The most unfavourable heating conditions are created by north-facing rooms that have two external walls. A general rule of thumb is that you can heat at least 15 - 20 m3 of room per kW of nominal heat output.

Room size

The dimensions of the room are used as a guide for selecting the stove. Basically, there are 4 insulation categories: built before 1970 (very poor insulation), renovated building 1970 - 1990 (average insulation), new building (good insulation) and energy saving building (very good insulation). For further information please contact your RIKA dealer.

Rotatable

The stove can optionally rotate up to 360 degrees, depending on the model, allowing you to enjoy the sight of the flickering flames from anywhere in the room.

IMPORTANT NOTE: In the case of the VITRA model, the optional turntable must be ordered for the rotating function. The TWIST model is offered as a rotating version. This cannot be combined with room sealed operation. Our RIKA dealer will be happy to advise you further.

Sandstone

Sandstone is a sedimentary rock (also called "aqueous rock") consisting of grains of sand cemented together that are predominantly made up of quartz.

Sealing lip

RIKA glass floor panels are fitted with a sealing strip to prevent dirt and humidity penetrating under the edges of the panel and becoming visible. To conceal the glued-on sealing lip, the glass panels are printed at the edges. This facilitates the cleaning process and preserves the visual appearance.

Self-cleaning system

A pre-programmed hourly cleaning process, during which the supply of pellets is temporarily interrupted, ensures the combustion cavity is blown free of any ash residues by increasing the speed of the flue gas fan.

Single handed operation

Single handed operation makes adjusting the combustion air supply easy and convenient.

Smouldering gases

During the pyrolysis phase (the burning of wood), fire-resistant gases also escape (so-called smouldering gases). Due to their aggressive nature and good heat output these should not end up in the heat exchanger, chimney or the surrounding environment.

Soapstone

Soapstone (schist, steatite; Italian pietra ollare; French pierre d'ollaire) is a group of natural stones that primarily consist of magnesium silicate/talc in a dense configuration. The stone is mined almost everywhere in the world. The stones can vary by region in terms of hardness and brittleness due to their composition. Minor components include magnesite, serpentine and various chlorites. Soapstone is ideally suited for use as a heat storage stone for stoves.

Solvent-free

The paint used on RIKA stoves is virtually solvent-free, for odourless heating from the very first day.

Storage mass

The storage mass of the stove is a crucial factor in determining how long it will retain and transfer its heat to the room after the fire has gone out. Basically, the higher the storage mass, the longer the stove will emit heat after the fire has gone out.

Stove dimensions

The stated dimensions refer to width (W) x height (H) x depth (D) of the stove.

SPECIAL NOTE: Please note the differing heights and widths when ordering a stove including a turntable or a base. For further information please contact your RIKA dealer.

Telephone modem (optional)

You can control your pellet stove electronically from your workplace, for example, via your mobile phone (e.g. via SMS).

Thermostat (optional)

Control via thermostat and saved heating times; automatic output adjustment.

Time burning

Time burning is when a larger quantity of wood is burned over a specific period of time (1-2 hours) and the energy, which is stored in the stove, is emitted later as radiant heat (e.g. soapstone stoves). For more information, please refer to the instructions supplied with the respective RIKA stove.

Touch Display

The intuitive touch display allows you to control all functions with the greatest of ease.

Triple values

The triple values are required by chimney sweeps for conducting a chimney calculation. These include the following three values: 1. Exhaust gas mass flow (closed) 2. Minimum supply pressure at nominal heat output (closed) 3. Exhaust gas temperature You can find the corresponding information in the instructions for your stove.

TSG GLASS

Toughened safety glass. RIKA glass floor panels are exclusively manufactured from 6mm TSG glass. The glass is thermally pre-tensed so that, if damaged, it does not shatter into sharp-edged fragments but instead into small blunt pieces of glass. This practically excludes all risk of injuries.

Upper air

The upper air, which is also referred to as secondary air, is the air required by the stove during the combustion and ember stage. This is supplied externally and contributes to a good combustion phase and also ensures the glass panel is kept clean (panel flushing). The air is channelled from above the panel and into the combustion chamber. After reaching the operating temperature (when the wood is burning sufficiently) the amount of air is regulated via the secondary air supply. The upper air supply, however, should never be closed completely during the firing stage, as this is the combustion air and it can lead to a blackening of the panels. If your stove is equipped with the intelligent RLS air distribution system, the distribution ratio of the lower and upper air/primary and secondary air is determined automatically.

USB port

The USB port allows you to update software quickly and easily, so that your stove will continue to have the latest functions also in future.

Vibrating grate actuator

The reciprocating motion of the vibrating grate actuator causes the ash to be transferred from the combustion chamber to the ash drawer. This leaves the path clear in the combustion chamber for the primary air, which is conducive to the heating phase. It is not necessary to actuate the vibrating grate during the heating phase.

VKF AEAI

VKF AEAI is the Vereinigung Kantonaler Feuerversicherungen (VKF) (Cantonal Fire Insurance Association) and it functions as the service and competence centre of cantonal building insurance companies for all activities associated with prevention on a national and international scale. The VKF is responsible for the coordination and standardisation of fire safety in Switzerland and its harmonisation with the EU. The VKF is also an accredited certification body for specialist personnel involved with fire protection installations. All models of RIKA stove are certified and approved by the VKF AEAI in terms of fire prevention.

Warm App

A graphical interface for smartphones and tablets (iOS Apple, Android) greatly facilitates the remote control of your stove.

Weather inversion

This is the designation of a weather situation which exhibits a stratification of air (usually characterised by calm or light winds). The temperature of the air layers normally decreases with an increasing altitude. Warm air masses, or e.g. exhaust gases, can rise to great heights because they have a lower density than the cooler ambient air. In the event of an inversion relatively warm layers of air typically occur at a height of 300-400 m above the cold layers of air close to the ground. The result is that rising exhaust gases, for example, lose their ascending force at a certain height and are held at this inversion layer as if they were under a bell jar.

Wood retainer

The wood retainer directs the upper air flow to the primary zone in a targeted manner and promotes turbulent flow.
