Installation Conditions and Relevant Building Regulations 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.

1.2 Type of construction

Design 2: Granada / Kyoto is supplied in design 2. Design 2 must be connected to chimneys catering for singular configuration only. Design 1: Design 1 allows the connection to chimneys catering for multiple configuration. Design 1 is achieved by limiting the opening of the combustion chamber to 500 cm2. Granada / Kyoto of design 1 must be operated closed only. Remodeling to design 1 By installing the reduction panel (also transport safety contrivance) the Granada / Kyoto meets the requirements of design 1. Insert and tighten panel as illustrated.

Safety and Safety Distances 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). If a floor plate is required, its size must match the rotating range of the stove. 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. 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. Modifying or making changes to the stove is not permitted. Only original replacement parts from Hase Kaminofenbau GmbH may be used.

When using a floor plate, the safety distances stipulated by DIN 18891 apply.

Installation 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 loadbearing capacity.

R ad i a t i n g A re a In addition, check whether the room in which the Granada / Kyoto 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.

The Chimney The Granada / Kyoto has to be connected to a suitable chimney with a minimum effective chimney height of 4.50 m. With the design 1 reduction panel 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 Granada / Kyoto 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 Granada / Kyoto stove has a maximum permissible output pressure of 35 Pa. Fig. 3 To limit the output pressure, a butterfly valve or output pressure limiter can be used.

Flue Pipe Connection The Granada / Kyoto has to be connected to the chimney with a flue pipe having an inside diameter of 15 cm. 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.

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 3 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 9 kW can be attained by burning wood logs weighing approx. 2,5 kg and approx. 25 cm in length for approx. 45 min. Butterfly Valve 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 To attain thermal output of 4,5 kW, burn wood logs weighing approx. 0,5 kg and approx. 25 cm in length for approx. 20 min. The Granada / Kyoto is intended for intermittent operation, please only apply one fuel layer at a time.

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

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.

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. 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. 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. Initial Operation 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 11, Adding Wood or Fuel/ Heating with Nominal Thermal Output, 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 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 Granada / Kyoto may only be operated when the fire box door is closed; the fire box door may only be opened to add fuel. Fig. 4 The control elements are located on the lower right side.

It is important to pass through the lighting phase quickly since during the lighting or firing phase, higher emission values may occur if mistakes are made. Therefore, for the sake of the environment, please observe the following closely. The stove should always be lit with wood. Due to the large fire chamber window of the Granada / Kyoto, it is particularly important to start the fire properly. Therefore, please ensure that you pay close attention to the instructions and information on the right side. Use only thoroughly dried wood, at best stored near the stove for several days (comply with safety distances). Softwood chips are particularly well-suited for kindling the fire (e.g. spruce). Lighting the Fire Procedure Position of Control Elements Completely open primary and secondary air. Pull primary and secondary air sliders all the way out. Open fire grate Pull out fire grate slider Slightly open ash drawer Pile up any remaining ash and unburned Charcoal into the centre of the combustion chamber. Place 2-3 small logs 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.

11. 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. Adding Fuel (Wood) Procedure Position of Control Elements Adjust primary and secondary air. Close primary air slider (I), set secondary air slider (II) to position 3-4. Close fire grate. Pull out fire grate slider. Add two logs weighing approx. 1.4 kg in total. Place logs with one end to the front of fire box. Only add a single layer of fuel. Open fire box door Close fire box door Open fire box door Wood should be added when the flames of the prior fire are about to die Close fire box door Once the wood is lit sufficiently on all sides close the ash drawer, and some 10-15 minutes later the primary air slide (I Set primary air valve (I) to zero Set secondary air slide (II) later to ideal position (after around 15-20 min.) Set secondary air valve (II) to 3 to 4 Tab. 2 Tab. 1

Thermal Output The thermal output of your Granada / Kyoto stove is primarily affected by the quantity of fuel used. Heating at Low Thermal Output Procedure Position of Control Elements Close primary air. Setl primary air slider (I) on position zero. Adjust secondary air. Set secondary air slider (II) between position 1 and 2. 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).

Place two thin logs (weighing c. 0.5 kg in total and measuring 25 cm in length) lying in the fire chamber Tab. 3

13. Emptying the Ash Drawer

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.

A piece of wood burns in three phases. In a wood fire, however, these processes take place both consecutively and simultaneously 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. 14.1. 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. 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 released at this point; flames can reach temperatures of up to 1100°C.

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

14.4 Expansion Noises

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. Burn-off Fig. 5 The Combustion Process

17. Contribution to Environmental Protection

Only fuels which generate low quantities of smoke may be burned in stoves. For the Granada / Kyoto, 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. Whether your Granada / Kyoto 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“). 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. 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.

16. The Chemistry of Wood

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.

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. 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.

18. 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.

19. 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.

20. 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.

21. Cleaning and Maintenance

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 sufficient63 ly 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 Granada / Kyoto 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.

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. To clean the flue gas paths/ducts, lift out the upper heat-resisting stone from the firebox. To access the flue gas paths for cleaning, use the connection port of the stove that is currently not in use. Any deposits or sediment in the flue gas paths/ducts can be brushed away and vacuumed up. Use a flexible pipe brush to clean the flue pipe at the cleaning port located on the flue pipe. If the flue pipe does not have a cleaning port, it can also be cleaned at the unused connection port.

21.3 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. 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:

For cleaning purposes, the entire glass front can be opened. (see illustration) 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.

21.4 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 heat-resisting 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.

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.
