Installation Conditions and Relevant Building Regulations

When using a floor plate, the safety distances stipulated apply.

The stove must be installed in accordance with the instructions and requirements stipulated by the respective national and European standards and local regulations. In Germany, the stove must be registered with the local master chimney sweep for inspection prior to initial operation. Safety and Safety Distances Floor plate

At the front and sides of the stove, no flammable, combustible or heat-sensitive materials (e.g. furniture, wood or plastic panelling, curtains, etc.) are to be located within a distance of 80 cm in the heat radiating area of the fire box window. In regards to flammable materials beyond the heat radiating area, a safety distance of 20 cm at the sides of and behind the stove has to be adhered to (see Fig. 3).

Children should never be left unattended near the burning stove. In accordance with the German Combustion Ordinance Draft, flammable flooring materials (wood, laminate, carpeting,) must be protected with a floor plate made of non-combustible material (tiles, safety glass, slate or sheet steel).

Distances to Heat-sensitive and Combustible Materials

In case of a chimney fire: - Ring the emergency telephone number to alert the fire brigade. - Notify your chimney sweep. - Never extinguish the fire with water! - Remove any flammable objects located in the vicinity of the chimney. - Wait for the fire brigade and chimney sweep to arrive.

Never use spirits, petrol or other flammable fluids to light the stove. During operation, the external surfaces of the stove become very hot, thus the entire stove poses a burn hazard. To ensure the safe operation of this stove, a glove is included in the scope of delivery.

Modifying or making changes to the stove is not permitted. Only original replacement parts from Hase Kaminofenbau GmbH may be used. 70

Layout for Wall Location

Layout for Corner Location

3.1 Akaba Standard Check to make sure that the load-bearing capacity of the floor / installation surface is sufficient. If necessary, using a floor plate to distribute the load can increase the load-bearing capacity. In addition, check whether the room in which the Akaba Standard is to be installed is sufficiently supplied with fresh air. If the windows and doors are tightly sealed, the necessary supply of fresh air may not be ensured, which can interfere with the draught capability of the stove and chimney. If additional combustion air inlet openings are required, they are not permitted to be closed or obstructed. Simultaneous operation of the stove and the exhaust hood can cause negative pressure to build up in the room where the stove is installed, which can lead to problems such as flue gas escaping from the stove. To ensure that air is not drawn out of the room where the stove is installed, we recommend locking exhaust hoods that guide the air to the outside by means of a window contact switch. 3.2 Akaba direct vent stove The door of the Akaba direct vent stove is self-locking. To ensure that the self-locking mechanism functions perfectly, use the spirit level to precisely align the Akaba direct vent stove in a horizontal position. The stove can be aligned by means of four levelling feet (see Assembly and Maintenance Instructions). Please make sure that there is sufficient ventilation in the room where the Akaba direct vent stove will be installed. For rooms with a cubic volume of more than 50 m³, an hourly air exchange ratio of 1.5 is required. With smaller rooms, the air change rate needs to be higher. The negative pressure in the room where the stove is installed is not permitted to

exceed the value of 8 Pascal (the ventilation system designer specifies the air pressure in Pascal units). We recommend setting the ventilation system to a maximum negative pressure of 4 Pascal. To ensure that no air is drained from the room, we recommend operating exhaust hoods in recirculation air mode or using a window contact switch to lock exhaust hoods that guide air to the outside. 4.

4.1 Akaba Standard The Akaba Standard has to be connected to a suitable chimney with a minimum effective chimney height of 4.50 m. It can be connected to a chimney to which other fireplaces are already connected. The chimney cross section should correspond to the flue pipe cross section. If the effective chimney height is too low and/or the chimney cross section is too large or too small, the draught capability of your stove can be impaired. The Akaba Standard stove requires a 12 Pa output pressure (chimney draft). At higher output pressures, the stove emissions increase, which puts a high load on the stove and can lead to damage. The Akaba Standard stove has a maximum permissible output pressure of 35 Pa. To limit the output pressure, a butterfly valve or output pressure limiter can be used. 4.2 Akaba direct vent stove The Akaba direct vent stove needs its own separate chimney. The draught capability of your stove can be impaired by a chimney cross section that is too large or too small and/or an effective chimney height of less than 4.50 m. The „effective chimney height“ is the distance between the flue gas intake in the chimney and the top of the chimney pot. After a soot fire in the chimney, the impermeability (air-tightness) of the flue gas paths has to be checked. We recommend connection to a multi-leaf chimney with a cross-section having a maximum diameter of 160 mm and a minimum „effective chimney height“ of 4.5 m. 71

If these specifications cannot be met, we advise you to check the suitability of the chimney by means of a chimney calculation. 5.

Flue Pipe Connection

5.1 Akaba Standard The Akaba has to be connected to the chimney with a flue pipe having an inside diameter of 120 mm - 150 mm. Please ensure a tight fit of all pipe pieces at the connection junctions. The pipe must be well sealed in the chimney entrance and cannot project into the inner cavity of the chimney; otherwise the flue venting will be impaired. 5.2 Akaba direct vent stove The Akaba direct vent stove has to be connected to the chimney with a flue pipe having an inside diameter of 120 mm - 150 mm. The flue pipe has to be sealed at the flue pipe connection piece with Hase Sealing Paste. The flue pipe connection to the chimney has to be gas proof and sealed with a suitable sealing cord and heat-resistant silicone (see Fig. 7). The flue pipe cannot project into the cross-section of the chimney, as that can impair flue venting. We recommend using a one-piece flue pipe. The total length of the connecting pipe between the stove and the chimney should not exceed 1.50 m. 6. Combustion Air Connection ( Akaba direct vent stove ) The combustion air in the fire box is solely supplied by a customer-provided supply air pipe and the Hase Air System pipe connections. The connecting piece for the Hase Air system is located on the back side of the stove. The sealed pipe connections are either routed directly to the outside or connected to a suitable air/flue gas system (AFS). Another option is to provide the supply air from a room with its own independent outside air supply (e.g. cellar or basement) (see Figs. 7 - 9). For the customer-provided installation of the air inlet, plain pipes (steel pipes in compliance 72

with 24145, drain pipes in accordance with DIN 19534 and EN 1451B) with a minimum diameter of 100 mm, a maximum of two bends and a permissible total length of 5 meters should be used. Verification by calculation is required for longer piping and more than two bends. The air supply pipe has to be equipped with an inspection opening for inspecting and cleaning purposes. The entire air supply pipe has to be airtight. We advise discussing this with your local planning officer. At the air inlet opening, we recommend installing an animal protection screen with a mesh size of 10 mm. 7.

Butterfly Valve ( Akaba Standard )

The butterfly valve is an optional control element. It is fitted in the flue pipe and used to regulate the flue gas flow, and can thus slow down the burning-off process. When the handle‘s position is diagonal to the flue pipe, the flue gas flow rate is turned to minimum. We strongly recommend the installation of a butterfly valve to reduce the output pressure. Please consider the country-specific statutory regulations.

Fuel Load Sizes and Thermal Output

The thermal output depends on the amount of fuel you burn in the stove (fuel load size). When adding more fuel (e.g. wood), the maximum fuel load size is 1 kg. Exceeding the maximum fuel load size leads to a danger of overheating, possibly resulting in damage to the stove and risk of a stove fire. A thermal output of 4 kW can be attained by burning wood logs weighing approx. 0,8 kg and approx. 20 cm in length for approx. 40 min. To attain thermal output of 2,5 kW, burn wood logs weighing approx. 0.3 kg and approx. 20 cm in length for approx. 20 min. The Akaba is intended for intermittent operation, please only apply one fuel layer at a time. 9.

Regulating the Combustion Air

When lighting the fire and adding fuel, the combustion air is regulated with the primary air and secondary slider.

9.2 Secondary Air The secondary air is guided into the fire box via air ducts from the top. It supplies the fire box with the volume of preheated oxygen necessary to completely burn off the wood gas and ensures that the fire box window remains free of soot. For regulating the secondary air, the following general rule applies: a small fire requires little secondary air; a large fire requires ample secondary air. If the secondary air valve is closed too tightly, there is the risk of the flue gases not completely burning (smouldering fire) and/or soot build-up on the fire box window or that the amassed wood gases will burn explosively (over firing/deflagration). Please note: Burning wood when the primary air slider is opened too wide poses the risk of overheating the stove (forge fire effect). During operation, the secondary air slider should never be completely closed. The fire box door and ash compartment must always be tightly shut.

9.1 Primary Air The primary air is guided through the grate and into the fire box from below, thus more quickly achieving the required fire box temperature during the warming up phase.

10. Initial Operation

11. Lighting the Fire

The first time you operate a stove, smoke and odours can develop as organic components in the coating, sealing strips and lubricants used in the production process burn off.

The firing up phase should be as short as possible, since higher emission value rates can occur during this phase.

At a higher combustion temperature, this one-time process can take between 4 to 5 hours. To achieve this higher combustion temperature, please increase the fuel quantity recommended in Section 12, Adding Wood or Fuel, by approximately 25%. To prevent adverse effects on health, nobody should stay in the room(s) where the stove is being operated unless absolutely necessary. Make sure the room is well-ventilated and open the windows and outside doors. If needed, use a fan for faster air circulation. If the maximum temperature isn’t reached during the first heating operation, you may notice an odour for a short period of time during subsequent operations as well. During shipment to you, condensation moisture can accumulate in the stove‘s interior, which may possibly lead to the appearance of condensation or water on the stove or flue pipes. Please dry off these damp areas immediately.

The slider settings described in Table 1 are recommendations that were determined under testing conditions, in compliance with the relevant standard. Depending on the weather conditions and the draught capability of your chimney, accordingly adjust the slider positions for your Akaba to the local conditions.

Lighting the Fire Procedure Completely open primary and secondary air.

Position of Control Elements Pull primary and secondary air sliders all the way out.

II Pile up any remaining ash and unburned Charcoal into the centre of the combustion chamber.

I Open fire box door.

Place ignition material into the middle of the fire box; stack approx. 0.5 kg of dry wood chips on top. Light the ignition material at several places. Close fire box door.

The surface of your stove was degreased in a sandblasting machine before being lacquered. Despite careful and thorough inspection, there may still be some blasting material (small steel pellets) in the stove body, which can fall out when your stove is being installed. To prevent any damage, please immediately vacuum up these little steel pellets with a vacuum cleaner. The Akaba may only be operated when the fire box door is closed; the fire box door may only be opened to add fuel.

As soon as the wood chips begin to completely burn, place two wood logs (approx. 0.5 kg total weight) with the small side facing forward.

12. Adding Fuel (Wood) More fuel (wood) should be added to the fire during the burning off phase, when the flames from the previous burning off phase have just gone out. When stoking the fire, open the fire box door very slowly to minimise the emergence of flue gases and prevent ashes from swirling up in the fire box.

Adding Fuel (Wood) Procedure Completely open primary and secondary air.

Position of Control Elements Pull primary and secondary air sliders all the way out.

II I Add a log weighing approx. 0.8 kg with the small side facing forward. Place logs with the bark facing upwards or outwards. Only add a single layer of fuel (wood).

After igniting the log, close the primary air and completely open the secondary air.

Push in primary air slider as far as it will go. Pull out secondary air slider as far as it will go.

13. Heating at Low Thermal Output The thermal output of your Akaba stove is primarily affected by the quantity of fuel used. Do not attempt to slow down the combustion by reducing the air supply. When heating with wood, this can result in an incomplete burning process and pose the risk of explosive-like combustion of the accumulated wood gases (deflagration).

Heating at Low Thermal Output Procedure

Position of Control Elements

Push in primary air slider (I) as far as the secondary air slider allows.

Completely open secondary air.

Pull out secondary air slider as far as it will go.

II I Add a log (approx. 0.3 kg) with the small side facing forward.

I Close fire box door.

14. Emptying the Ash Drawer

released at this point; flames can reach temperatures of up to 1100°C.

For safety‘s sake, please make sure that you only dispose of ashes once they are cold. While the ash collects, the lid is located under the ash drawer.

Unlock the ash drawer. Remove both the ash drawer and the lid located underneath it. Slide the lid onto the ash drawer so that it is closed; this prevents ashes from flying around, which in turn means your home stays clean. To place the ash drawer back into the stove, proceed in the reverse order. Piled up ashes can prevent or even block the primary air supply to the stove. Ensure that the ventilation path for the primary air between the ash drawer and the bottom of the ash compartment remains clear.

Glowing charcoal embers remain after the volatile components have been burned off. These burn slowly, almost without flames, at a temperature of approx. 800°C. Crucial to a clean and efficient combustion process is a complete (as possible) chemical reaction of the wood gases with the oxygen in the combustion air. With your Hase stove, the combustion air is pre-heated and guided into the fire box via wide air inlet openings, enabling a good and thorough mixing of the gases with the air. An important variable in any combustion phase is the amount of combustion air. Not enough air leads to an oxygen deficiency and incomplete combustion, while too much air reduces the fire box temperature and thus the efficiency. Incomplete combustion can

15. The Combustion Process A piece of wood burns in three phases. In a wood fire, however, these processes take place both consecutively and simultaneously 15.1 Drying Phase

The moisture still remaining in the air-dried wood (approx. 15 - 20%) is evaporated. This takes place at temperatures of approx. 100°C. For the evaporation to occur, the wood must be supplied with heat during the warming up phase; this is achieved by using small wood logs. 15.2 Degasification Phase

At temperatures of between 100°C and 150°C, the contents of the wood start (slowly at first) to disintegrate and gasify and the wood begins its thermal decomposition. At temperatures above 150°C, the gas development increases strongly. The proportion of volatile components makes up around 80% of the wood substance.

At a temperature of about 225°C (ignition temperature), the actual combustion begins with the ignition of the resulting gases and the release of heat. There must be an adequate supply of oxygen available for this purpose. The peak of the combustion process is reached at approx. 300°C. The reaction process is now so rapid that the largest amount of heat is

generate air pollutants such as dust, carbon monoxide and hydrocarbons.

17. The Chemistry of Wood

15.4 Expansion Noises

Wood predominantly consists of the elements carbon, hydrogen and oxygen. It contains virtually no environmentally hazardous substances such as sulphur, chloride and heavy metals. As a result, complete wood combustion produces mainly carbon dioxide and water vapour as the primary gaseous products as well as a small quantity of wood ash as the solid combustion residue.

Steel expands upon heating and contracts as it cools, which can cause your stove to emit audible expansion sounds. However, the design and construction of your stove takes this into account and prevents this physical process from damaging the stove. 16. The Right Fuel Only fuels which generate low quantities of smoke may be burned in stoves. For the Akaba, only natural, untreated, beechwood logs, including the adherent bark, can be used as fuel. Highly resinous coniferous wood (e.g. spruce, pine, fir) tends to emit flying sparks and leaves behind a fine layer of flue ash that can swirl up when the fire box door is opened. For the most attractive stove fire, use beech wood logs. If other types of wood are used, such as oak, birch, pine or larch, we recommend adding beech wood for picturesque dancing flames. Brushwood and small pieces of wood are good kindling materials. he burning of e.g.: - damp or moist wood (residual moisture content over 20%), - varnished or plastic-coated wood, - wood treated with wood preservatives, - household waste, or - paper briquettes (pollutants: cadmium, lead, zinc) - any flammable fluids (including methanol and ethanol) as well as any fuel pastes or gels is not permitted.

On the other hand, incomplete combustion can generate a number of pollutant substances, such as carbon monoxide (toxic), acetic acid, phenols, methanol (toxic), formaldehyde, soot and tar. 18. Contribution to Environmental Protection Whether your Akaba burns in an environmentally-friendly or environmentally hazardous manner depends to a large extent on how you operate it and the type of fuel you use (see „The Right Fuel“). Use only dry wood; hardwoods such as birch and beech are most suitable Only use small pieces of wood to light the fire. They burn faster than large logs and thus the temperature required for complete combustion is reached more quickly. For continual heating, adding smaller quantities of wood more frequently is more efficient and more ecological.

Combustion of the materials listed above not only gives off unpleasant odours, but also generates emissions that damage the environment and are harmful to health.

19. Evaluating the Combustion Quality The following characteristics can facilitate easy evaluation of the combustion quality: - Colour and composition of the ash If the combustion process is efficient, the result is a fine white ash. Dark colouration indicates that the ash contains charcoal residue; in this case, the burn-off phase was incomplete. - The colour of the flue gases emitted at the chimney pot In this respect, the following applies: the more invisible the flue gases exiting the chimney, the better the combustion quality. During the transitional seasons (spring/autumn), outdoor temperatures above 16°C can impair the chimney draught. If a draught cannot be created at these temperatures by rapidly burning paper or thin wood shavings (quick fire), you should refrain from lighting the stove. 20. Wood Moisture Content and Calorific Value Rule of thumb: the more damp the wood, the lower the calorific value The calorific value of the wood depends largely on the wood moisture content. The more moisture the wood contains, the more energy expended to evaporate it during the combustion phase; this energy is then lost. Thus, the more damp the wood, the lower its calorific value. An example: freshly cut wood has a moisture content of approx. 50% and a calorific value of around 2.3 kWh/kg; in contrast, wood which has been efficiently air-dried has a moisture content of approx. 15% and a calorific value of around 4.3 kWh/kg. Accordingly, if you burn very moist wood, you will have about half the thermal output with the same quantity of wood. Furthermore, burning moist wood results in substantial soot build-up on the fire box window.

Moreover, when moist wood is burned, the resulting water vapour can condense in the flue pipe or chimney. This can lead to a build up of shiny soot on the chimney or chimney

creosote. In addition, if the wood has a high moisture content, the combustion temperature decreases, which prevents complete combustion of all the wood components and causes considerable environmental pollution. You can use a wood moisture meter to determine the residual moisture content of your firewood. 21. Storing and Drying Wood Wood needs time to dry. If stored properly, it will air-dry in approx. 2 to 3 years. Saw, split and store the wood ready for use; this ensures rapid drying because smaller pieces of wood dry better than larger, uncut logs. Stack and store your wood logs in a ventilated and as sunny as possible location, ideally facing south, and ensure that they are protected from rain. Leave a hand‘s width between the individual piles of wood so that air can flow between them and carry away any escaping moisture. Do not cover your stacks of wood with plastic sheeting or tarpaulins; otherwise the moisture cannot escape. Do not stack fresh wood in a cellar or basement, since it will rot rather than dry due to the lack of airflow. Only store already dried wood in dry and wellventilated cellar or basement rooms.

22. Cleaning and Maintenance

22.3 Ceramic Glass Panels and Windows

When the stove is properly operated, the secondary air simultaneously forms an air curtain at the pane, which prevents the glass from becoming sooty.

Hase stoves are coated with a heat-resistant open porous lacquer that provides only limited corrosion protection; accordingly, a rust film may develop in some cases. Do not use any detergents containing acid (e.g. citrus or vinegar cleaners) to clean the steel parts. The steel parts can be sufficiently cleaned by wiping them down with a slightly moistened cloth. Avoid using excessive water to clean the floor/floor plate areas. Spilt water from kettles, boilers or water tanks should be immediately mopped up. Do not install the Akaba in „damp rooms“, e.g. conservatories or enclosed porches. Avoid temporary storage in unheated building shells or garages. Treat areas covered in a rust film with the original Hase Stove Lacquer Spray. Be sure and follow the instructions on the spray can. Your authorised Hase specialist dealer stocks the stove lacquer spray and can give you tips on using it. 22.2 Flue Gas Paths The stove and flue pipes should be inspected for sediment and deposits at the end of each year‘s heating period (even more often if required, e.g. after the chimney has been cleaned), and cleaned if necessary.

If ash particles get on the ceramic glass panels, we recommend, as an alternative to conventional glass cleaners, a tried and true environmentally-friendly cleaning method: Take some balled-up paper towelling or newspaper, moisten it, dip it into the cold wood ash, rub the panel with it and then wipe the glass with a clean, dry ball of paper. 22.4 Fire Box Lining The heat-resisting stones in your stove‘s fire box are made of Vermiculite. Vermiculite is a fire-resistant mineralogical granulate material with excellent insulating properties. The density of the slabs is a result of the optimal balance between mechanical stability and insulation properties. The relatively soft surface is subject to natural wear and tear, depending on use. The heatresisting stones have to be replaced if parts break off and the back wall of the fire box, located behind the slabs, becomes visible. Tears or cracks in the heat-resisting stones do not impair the functioning of your stove. To reduce the damage to the heat-resisting stones, place logs carefully in the fire box and do not let them fall against the walls of the fire box.

To clean the flue gas paths, lift out the upper heat-resisting stone from the fire box. Any soot or dust sediment / deposits can be brushed off and vacuumed away. Then re-insert the heat-resisting stone. Use a flexible pipe brush to clean the flue pipe at the cleaning port located on the flue pipe.

22.5 Sealing Strips The sealing strips for the fire box door and ash box are made of highly heat-resistant, asbestos-free fibreglass. The sealing strips are wearing parts and thus have to be replaced in line with the frequency of use. We advise having your stove regularly inspected by a specialist. For more information, please refer to the Assembly and Maintenance Instructions.
