The chimney stoves of La Nordica are suitable to heat living spaces for some periods. As fuel, wood logs are used. The stove is made of sheets in galvanized and painted steel, of cast iron (grate and grate holder of the hearth, exhaust pipe) of stone and majolica tiles. The hearth is totally sheathed with cast-iron single sheets and refractory material (IRONKER). Inside there are a easy extractable thick flat grate and its holder. The combustion chamber is hermetic welded and is sheathed with a painted steel carter. The inside smoke plate made of vermiculite, reflects the fire radiation and increases the internal temperature of the combustion chamber. This process together with the exhaust gases flows, makes optimal the combustion and improves the efficiency. (Pag.60) The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderful v iew on the burning flames. Furthermore, it is thus avoided the output of sparks and smoke. Below the hearth door will be found an extractable ash-drawer with a closing door. The heating of the environment is made: a) by radiation: through the panoramic glass and the external hot surfaces of the stove, the heat is radiated into the environment. The chimney stove is equipped with registers of primary (Picture 1 pos.A) and secondary air (Picture 1 pos.B), by which it is adjusted the combustion air.

PRIMARY AIR REGISTER

With the air register placed below the hearth door (right Picture 1 A) it is adjusted the passage of air through the ash drawer and the grate in the fuel direction. The primary air is necessary for the combustion process and to keep the fire alive. The ash drawer must be regularly emptied, so that the ash does not obstruct the primary air entry for the combustion. During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns fast and the stove may overheat. (see paragraph 10). SECONDARY AIR REGISTER (Picture 1 B) Over the hearth door there is the secondary air register. Also this control must be opened (then moved to the right), especially for wood combustion, so that unburnt carbon does not undergo a post-combustion . (see paragraph 10).

3. RULES FOR INSTALLATION

The stove, assembled and ready for the installation, must be connected with a junction to the existing flue of the house. The junction must be possibly short, straight, horizontal or positioned a little uphill. The connections must be tight. It is obligatory to respect the National and European rules, local regulations concerning building matter and also fireproof rules. Please apply to your chimney sweeper for all information. You should verify the sufficient air entrance for the combustion in the installation place, with particular attention to windows and doors with tight closing (seal ropes). It is not allowed the connection of various appliances to the same chimney. The diameter of the opening for the connection must correspond at least to the diameter of the smokes pipe. The opening should be equipped with a wall connection for the reception of the exhaust pipe and a rose window. Before installation, verify if your floor can support the weight of the stove (for ex. distributing weight plate). LA NORDICA is not responsible in case of modification of the product and for the use of not original spare parts. THE HEARTHS MUST NOT BE MODIFIED.

In the installation of the stove the following safety measures are to be followed: a) the minimum distance from the rear and both sides from construction and inflammable objects and objects sensitive to heat (furniture, wooden coverings, textiles etc.), must be that indicated on the technical data plate fixed to the product (see Picture 2 A) in order to ensure sufficient heat insulation. All the minimum safety distances are shown on the product data plate and lower values must not be used. b) In front of the chimney stove there must not be any flammable object or building material, sensitive to heat, at less then 100 cm’s. of distance. This distance can be reduced to 40 cm’s if you will install in front of the element to protect a retro ventilated and heat resistant protection. c) If the product is installed on a non totally refractory floor, one must foresee a fireproof background. The floors made of inflammable material, such as moquette, parquet or cork etc., must be replaced by a layer of no-inflammable material, for instance ceramic, stone, glass or steel etc. (dimensions according to the local regulations). The base must stick out 50 cm’s in front and 30 cm’s sideways, considering also the rotation field of the stove. (see Picture 2 B). d) no flammable components (e.g. wall units) must be present above the product. e) If the stove is installed on a wall made of flammable material, it is necessary to replace that part of the wall with a non-flammable material layer, for instance ceramic, stone, glass or steel etc. The replaced part of wall must be as large as the stove is and, starting from the floor, protrude around 100 cm at least (Picture 2 C) from the top side of the stove.

The stove must work exclusively with inserted ash drawer. Solid combustion residuals (ashes) must be collected in an air-tight and fire-resistant container. The device must never be switched on when there are gaseous emissions or vapors (for example glue for linoleum, gasoline etc.). Do not deposit flammable materials close to the same. During the combustion will be spread thermal energy which warms up the surfaces, the door, the fireplace glass, the handles and knobs, the smoke pipe and the front side of the stove. Please avoid the contact of these parts without gloves or the relevant tools. Warn children of the danger and keep them away during the operation of the stove. The use of a wrong or wet fuel causes the formation of creosote deposits in the flue and will fuel a chimney fire.

A BCORTINA – CORTINA Forno 7196100 Rev.08 – EN 21 4.1. FIRST-AID MEASURES Should any fire arise in the stack or in the flue: a) Close the feeding door and the ash drawer door. b) Close the registers of combustion air c) Extinguish the fire using carbon dioxide fire-fighting means (CO

dust). d) Seek immediate intervention of FIRE BRIGADE. DO NOT EXTINGUISH FIRE USING WATER JETS. When the fire has been extinguished, let the flue check by an expert to find possible cracks and permeable points.

Essential requirements for a correct operation of the appliance:

• the internal section must be preferably circular;

• be thermally insulated and water-proof and produced with materials suitable to resist to heat, combustion products and possible condensates;

• not be throttled and show a vertical arrangement with deviations not greater than 45°;

• if already used, it must be clean;

• observe the technical data of the instructions manual; Should the flues have a square or rectangular section, internal edges must be rounded with a radius not lower than 20 mm. For the rectangular section, the maximum ratio between the sides must be ≤ 1.5. A too small section causes a decrease of the draught. It is suggested a minimum height of 4 m. The following features are forbidden and therefore they endanger the good operation of the appliance: asbestos cement, galvanized steel, rough and porous internal surfaces. Picture 3 gives some examples of execution. The minimum section must be 4 dm

(for example 20 x 20 cm) for appliances whose duct diameter is lower than 200 mm, or 6.25 dm

(for example 25 x 25 cm) for appliances with diameter greater than 200 mm. The draught created by the flue must be sufficient, but not excessive. A too big flue section can feature a too big volume to be heated and consequently cause difficulties in the operation of the appliance; to avoid this, tube the flue along its whole height. A too small section causes a decrease of the draught. The flue must be properly spaced from any flammable materials or fuels through a proper insulation or an air cavity. It is forbidden to let plant piping or air feeding channels pass in the same flue. Moreover, it is forbidden to create movable or fixed openings on the same for the connection of further other appliances. 5.1. CHIMNEY CAP The draught of the flue depends also on the suitability of the chimney cap. The refore, if it is handicraft constructed, the output section must be more than twice as big as the internal section of the flue.

Picture 3 (1) AISI 316 steel flue with double chamber insulated with material resistant to 400°C. Efficiency 100% excellent. (2) Refractory flue with insulated double chamber and external coating in lightweight concrete. Efficiency 100% excellent. (3) Traditional clay flue showing a square section with cavities. Efficiency 80% excellent. (4) Avoid flues with rectangular internal section who se ratio differs from the drawing. Efficiency 40% poor. A+1/2A

(4)CORTINA – CORTINA Forno 22 7196100 Rev.08 – EN Should it be necessary to exceed the ridge of the roof, the chimney cap must assure the discharge also in case of windy weather (Picture 4).

The chimney cap must meet the following requirements:

• have internal section equivalent to that of the stack.

• have a useful output section twice as big as the flue internal one.

• be manufactured in such a way as to prevent the penetration of rain, snow, and any other foreign body in the flue.

• be easily checkable, for any possible maintenance and cleaning operation.

Picture 6 (1) The chimney cap must not show hindrances within 10 m from walls, pitches and trees. Otherwise raise it of at least 1 m over the hindrance. The chimney cap must exceed the ridge of the roof of at least 1 m.

(1) Industrial chimney cap with pre- fabricated elements – it allows an excellent discharge of the smokes. (2) Handicraft chimney cap.

The right output section must be at least twice as big as the internal section of the flue (ideal value: 2.5 times).

(3) Chimney cap for steel flue with internal cone deflector of smokes.

(1) In case of flues side by side, a chimney cap must be higher than the other one of at least 50 cm in order to avoid pressure transfers between the flues themselves.CORTINA – CORTINA Forno 7196100 Rev.08 – EN 23

For safety reasons the door of the appliances with constructive system 1, must be opened only for the loa ding of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth must remain closed. The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under supervision. The stove is endowed with an upper exhaust pipe. The connection pipe to the flue must be the shortest possible, right, tight and according to the current regulations. The connection to the chimney must be performed with stable and strong pipes (we recommend a thickness of 2 mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameter

This is ensured by pipes according to DIN 1298. ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must be changed with fireproof and not sensitive to heat materials. For a good operation of the equipment it is essential that in the installation place it is introduced sufficient air for combustion (see chapt. 7). The depression on the chimney should be 12 - 13 Pa (=1.2 – 1.3 mm of water column). The measurement must be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA (1.7mm of water column) it is necessary to reduce the same with the installation of an additional flue adjuster (butterfly valve) on the exhaust pipe or in the chimney. For safety reasons the door of the stove must be opened only for the loading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth must remain closed.

7. AIR ENTRANCE INTO THE INSTALLATION PLACE DURING THE COMBUSTION

As the stoves take their combustion air from the installation place, it is essential that a sufficient quantity of air is introduced in the installation room itself. In case of tight doors and windows (for example houses built according to the energy saving criteria) it is possible that the air entrance is not guaranteed, compromising the draught, the welfare and the security of the people. It is necessary to guarantee a further air entrance through an external air intake, to be positioned in the nearby of the appliance or through air connection towards outside or a near ventilated room, with the exception of thermal units place or garages (FORBIDDEN). The connection pipe must be flat with a minimum diameter of 120 mm, a maximum length of 4 m and with no more than 3 bends. If there is a direct connection with the outside it must be endowed with a special windbreak. The air entrance for combustion into the installation place must not be closed during the operation of the stove. It is absolutely necessary that in the environment in which the stoves operate with the natural flue of the chimney, it is introduced as much air as necessary for the combustion, i.e. up to 20 m³/hour. The natural recirculation of air must be ensured by some fixed openings on the outside. The size of the necessary openings for air is fixed by the relevant prescriptions. Ask for information to your chimney sweeper. The openings should be protected with grids and should never be obstructed. An extraction hood (aspirating) installed in the same room or in a room nearby, causes depression with output of combusted gasses (smoke, smell). As consequence the extraction hoods should not work at the same time of the stove. The depression in an extraction hood can at worst hypothesis, transforms the flue into an external air intake, by sucking the smokes of the rooms with dangerous consequences for the people. OPTIONAL For a better comfort and corresponding oxygenation of environment, the stove combustion air can be directly withdrawn at the outside. In order to do that, the stove can be connected to the external air socket by an optional junction (Picture 8 - A) ( Kit Ø 120 ).

8. ADMITTED/NOT ADMITTED FUEL

The fuels admitted are wood logs. One must use only logs of dry wood (water content max. 20 %). The size of wood logs should be 30 cm’s long and 30 cm’s max in circumference.

• RESINOUS WOOD NOT SUITABLE FOR THE BURNING The wood used as fuel must have a moisture contents lower than 20 %, which is obtained after at least 1 year drying (tender wood) or 2 years (hard wood) and must be stored in a dry and ventilated place (for ex. Under a shed). The wet wood makes ignition more difficult because it is necessary a greater quantity of energy to evaporate the existing water. The humid contents has the disadvantage that, with the temperature lowering, the water condensates first in the hearth and then in the chimney. The unseasoned wood contains about 60 % of H20, then it is not suitable to be burnt. The following cannot be burnt: rests of coal, cut-offs, parts of barks and panels, wet wood or treated with varnished, plastic materials. In this case the guarantee on the appliance lapses. Paper and carton must be used only for ignition. The combustion of wastes is forbidden by national law on the protection against emissions. This may damage the stove and the chimney, causing health damages and claims by the neighbourhood owing to the bad smell. The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the night is not possible. ATTENTION: the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the cast iron parts (cleavage) of the product.

IMPORTANT: The first time that the appliance is lit, there will be an odour given off (due to the drying of the adhesives of the junction chord), which disappears after a short use. It must be ensured, in any case, a good ventilation of the environment. Upon the first ignition we suggest loading a reduced quantity of fuel and slightly increasing the calorific value of the equipment. To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to know the following information:

• the construction materials of the involved products are not homogeneous, as matter of fact there are simultaneously parts in cast iron, steel, refractory material and majolica;

• the temperature to which the body of the product is subject is not homogeneous: from area to area, variable temperatures within the range of 300°C - 5 00 °C are detected;

• during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as well as to cycles of intense use or of absolute standstill when season changes;

• the new appliance, before being considered seasoned has to be subject to many start cycles to allow all materials and paints to complete the various elastic stresses;

• in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal stress, as well as of wet paint. This paint, although during the manufacture it is backed at 250 °C for some hours, must exceed many times and f or a given period of time the temperature of 350 °C before becoming completely embedded in the m etallic surfaces. Therefore, it is extremely relevant to take these easy steps during the lighting:

1) Make sure that a strong air change is assured in the room where the appliance is installed.CORTINA – CORTINA Forno

26 7196100 Rev.08 – EN

2) During the first starts, do not load excessively the combustion chamber (about half the quantity

indicated in the instructions manual) and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in the instructions manual.

3) Repeat this operation for at least 4-5 or more times, according to your possibilities.

4) Then load more and more fuel (following in any case the provisions contained in the installation

booklet concerning maximum load) and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.

5) During the first starts, no object should be leaned on the appliance and in detail on

enamelled surfaces. Enamelled surfaces must not be touched during heating.

6) Once the «break-in» has been completed, it is possible to use the product as the motor of a car,

avoi ding abrupt heating with excessive loads. To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means. It is FORBIDDEN to use any liquid substance as for ex. alcohol, gasoline, oil and similar. The register of primary air must be completely opened. When wood starts to burn, it is possible to feed it again, close the primary air control (completely moved to the left) control the combustion through the secondary air register according to the provisions of paragraph 10. Please always be present during this phase. Never overload the appliance (see the technical table - max. quantity of fuel that can be loaded / hourly consumption . Too much fuel and too much air for combustion can cause overheating and therefore damage the same.

10. NORMAL OPERATION

For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth must remain closed. The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under supervision. IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The hearth door must always remain closed during operation or rest. The nominal power of the appliance is of kW 6.5. This power will be reached with a minimum depression in the chimney of 12-13 Pascal (=1.2 - 1.3 mm of water column). With the control located on the front of the appliance (Picture 1 A), it is possible to adjust the heat emission of the same. This is to be opened according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most part of the air for combustion flows through the secondary air register. Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and too much air for the combustion may cause overheating and then damage the stove. You should always use the CORTINA with the door closed in order to avoid damages due to overheating (forge effect). The inobservance of this rule makes the warranty expire. FUE L Wood (length 30cm, circumference 30 cm ) Max quantity in ( kg /h)

Primary air Picture 1 pos.A) CLOSED Secondary air Picture 1 pos.B) OPEN The CORTINA is an appliance with intermittent operation.CORTINA – CORTINA Forno 7196100 Rev.08 – EN 27 Besides the adjustment of air for combustion, the intensity of the combustion and consequently the thermal performance of your appliance is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor draught requires a more precise adjustment of air for combustion. To verify the good combustion, check whether the smoke coming out from the stack is transparent. If it is white, it means that the appliance is not properly adjusted or the wood is too wet; if instead the smoke is grey or black, it signals that the combustion is not complete (it is necessary a greater quantity of secondary air.

11. OPERATION IN TRANSITION PERIODS

During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that the combustion gases inside the flue cannot be completely sucked up. The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the stabilization of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tight.

12. OVEN OPERATION (if present)

After shaking the grate, load some fuel. Thanks to the air flow for the combustion, the temperature of the oven may become remarkably affected. A good draught of the chimney and channels well cleaned for the flow of burning smokes around the oven are fundamental for a good cooking result. The oven pan may be located on different plans. Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reach the medium level. The upper level may be used to heat or grill.

13. MAINTENANCE AND CARE

Let the installation of your stove, the connection to chimney and the ventilation check by your chimney swee per. For the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive detergents. IMPORTANT: It is possible to use exclusively spare parts clearly authorized and offered by LA NORDICA. In case of need please apply to your dealer! THE APPLIANCE CAN NOT BE MODIFIED!

13.1. CLEANING OF THE FLUE

A correct lighting, the burning of a proper fuel, the loading of the suggested quantity of fuel, the right adj ustments of the secondary air control, the sufficient draught of the chimney and the presence of air for the combustion, are essential for the good operation of the appliance. The appliance should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield).The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper who can simultaneously perform an audit of the flue (checking of possible deposits). During the cleaning, it is necessary to remove from the appliance the ash drawer and the smokes pipes. It is possible to clean the space for the collection of smokes from the hearth or through the smoke exhaust, by using a brush and a vacuum cleaner. Once the cleaning has been completed, the same has to be positioned back in its seat.

13.2. CLEANING OF THE GLASS

Thanks to a specific entry of the secondary air the building of deposit on the glass of the door is slowed down in a remarkable way. However the building of this deposit cannot be avoided with the use of solid fuels such as wet wood, and this is not to be considered as a defect of the appliance. IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold appliance to avoid the explosion of the same. Do not use cloths, abrasive or chemically aggressive products by cleaning the hearth glass.CORTINA – CORTINA Forno 28 7196100 Rev.08 – EN The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance and for the cleaning of the glass. BREAK OF GLASSES: Considering that the glasses are manufactured in glass- ceramic and resistant to heat shock up to 750 °C, t hey are not subject to thermal shocks. Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, their replacement is not included in the warranty.

13.3. CLEANING OF THE HEARTH GRATE

The use of not suitable fuel, as for example wood with sand, prevents the correct sliding of the cast-iron grate and can lead it to the complete blockage. In this case you should arrange for a removal of the dirty sediments from the surfaces of the grate and its holder Picture 9.

13.4. CLEANING OF THE ASH DRAWER

All the appliances are equipped with a hearth grate and an ash drawer for the collection of the ashes (Picture 10 pos. A) .It is suggested to empty periodically the ash drawer and to avoid it fills completely in order not to overheat the grate. Moreover, we recommend leaving always 3-4 cm of ash in the hearth. ATTENTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped with an air-tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the switching off and complete cooling. 13.5. MAJOLICAS LA NORDICA has chosen majolica tiles, which are the result of high-quality artisan work. As they are completely carried out by hand, the majolica may present crackles, speckles, and shadings. These characteristics certify their precious origin. Enamel and majolica, due to their different coefficient of dilatation, produce microcrackles, which show their authentic feature. For the cleaning of the majolica we suggest you to use a soft and dry cloth; if you use a detergent or liquid, the latter might soak in and highlight the crackles permanently.

After you have cleaned the hearth, the chimney and the flue, trying to eliminate completely the ash and others residuals, close the doors of the hearth and its registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work others possible appliances connected to the same flue. The cleaning of the flue should be done at least once a year; in the meanwhile check the state of the gaskets, which if not perfectly intact, that is to say that they are not more close-fitting with the stove, do not guarantee the good working of the stove! In that case the gaskets must be replaced. In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the hearth. If you want to keep for long the aesthetic look of the stove it is important to protect its internal walls in cast iron with neutral Vaseline.

The smoke channel is the section of tube that connects the product to the flue, in the connection these simple but very important principles must be followed:

• for no reason must the smoke channel be used with a diameter lower than that of the neck of the outlet with which the product is fitted;

• each metre of horizontal route of the smoke channel causes a small leak of charge which should be compensated for by raising the flue;

• the horizontal section must never be higher than 2 m (UNI 10683-2005);

• each bend of the smoke channel considerably reduces the draught of the flue which must be compensated for by raising it suitably;

• the UNI 10683-2005 Regulation –Italy requires that the bends or variations of direction must in no case be greater than 2 including the emission into the flue. Wanting to use the flue of a chimney or open furnace, it will be necessary to close the hood hermetically below the inlet point of the smoke channel pos. A Picture 11. If the flue is too large (e.g. cm 30x40 or 40x50) it is necessary to duct it with a stainless steel tube of at least 200 mm of diameter, pos. B taking care to close the space between the tube itself and the flue immediately below the chimney cap pos. C.
