5 . Single chimney or flueway DT Every appliance must have a vertical flue pipe operating by natural draught to discharge the combustion gases outdoors. The flue must: --comply with regulations in force in the place of installation of the appliance; --be tight to the products of combustion, waterproof, suitably insulated, made with materials resistant to the corrosion of the gases and to stress; --be connected to just one stove, fireplace or extraction hood (Fig. 2); --be properly sized, with constant free internal section, equal to or greater than the diameter of the flue pipe of the stove and at least 3.5 m in length (Fig. 2); --be mainly in a vertical position with a deflection from the axis of no more than 45 (Fig. 2); --be at a suitable distance from combustible or flammable materials, ensured by an air gap or suitable insulating material; --be of uniform internal section, preferably round. Square or rectangular sections must have rounded corners with a radius of at least 20mm and a maximum ratio between the sides of.5 (Fig ); --the walls must be smooth if possible and without narrowing; bends must be regular and without discontinuity (Fig. 6). Fig. 2 MIN 3,5 M MAX 45 NO ddit is forbidden to make fixed or mobile apertures on the flue pipe to connect appliances other than the one to which it is already connected. ddit is forbidden to pass other air ducts or service pipes inside the flue pipe, however large it is. aaif the flue pipe is an incorrect size or installed other than in compliance with the above instructions, Gruppo Piazzetta S.p.A. cannot be held liable for malfunctioning of the product, damage to property or injury to persons or animals.

(Fig. ) H072067UK0 / DT

6 .3 Chimney STACk DT The chimney stack is a device fitted on the top of the chimney that is designed to aid dispersion of the products of combustion in the atmosphere. The chimney stack must comply with the following requirements: -- it must have an internal section and shape the same as the flue (A); -- it must have a useful outlet section (B) of not less than twice that of the flue (A); -- the part of the chimney that emerges from the roof or remains in contact with the outside (e.g. in the case of a flat roof), must be covered with brick or tile elements and in any case well insulated; -- it must be built in such a way as to prevent the penetration of rain, snow and foreign matter into the flue and to ensure that in the event of winds from all directions and angle, discharge of the combustion products is assured (chimney stack with down-draught cowl). Fig. 7 A B* * B it is twice of to A DT Fig. B A B DT Recommended distances for correct chimney operation. To ensure trouble-free operation of the chimney and allow correct dilution of the products of combustion in the air, the chimney stack must be installed at the distances given below: metres from any buildings or other obstacles that are higher than the chimney stack; centimetres higher than any obstacles located at a distance less than 5 metres; -- outside the reflux area. The size and shape of this area differ according to the angle of inclination of the roof and it is therefore necessary to adopt the minimum heights shown below. Fig m Example: Check the slope of the roof (column α), and the anticipated distance of the chimney stack from the axis of the ridge (column A), if the distance is greater than A the height of the chimney stack may be read in (column H); if the distance is less than A the chimney stack must rise above the ridge by 0.5 metres.

7 .4 Fresh air intake DT To ensure trouble-free operation the stove/fireplace must have the necessary air available for combustion and this is provided through the fresh air intake. The fresh air intake must: --have a total free cross section at least equal to the size given in the paragraph TECHNICAL DATA ; --be protected by a grille or suitable guard provided it does not reduce the minimum recommended section; --be in a position whereby it cannot be obstructed. Fig. 2 Fig. 3 DT DT The airflow necessary for the fire may be obtained in different ways: --through a fresh air intake direct into the room of installation; --with ducting through pipes direct to the room of installation, increasing the recommended minimum free cross section by at least 5%; --from an adjacent room to the place of installation provided this air flows freely through permanent apertures communicating with the outside. Fig. 4 aathe adjacent room from which air is taken must not have a low pressure compared to the exterior due to a counter draught caused by the presence in that room of another appliance in use or of a suction device. The permanent apertures in the adjacent room must comply with the requirements given above. ddcombustion air must not be taken from adjacent rooms used as a garage or a combustible materials store or for activities posing a fire hazard. Fig. 5 DT DT INSTALLATION environment DT The appliance should be installed in a location which allows safe and convenient use as well as easy maintenance. If the product being installed requires an electrical socket, the room must also be provided with an earthed power supply in accordance with current regulations. The room where the appliance is to be installed must comply with the following requirements: aathey must not be used as a garage, store for combustible material or for activities with a risk of fire. aathey must not be in a vacuum in relation to the outside environment due to the effect of contrary draught caused by the presence in the room where the fi replace is installed of another appliance or an extractor device. aado not use two stoves, a fireplace and a stove, a stove and a wood-fired cooking range, etc. in the same environment, since the draught of one could affect the draught of the other. Devices suitable for cooking food with relative hoods without an extractor fan may only be used in kitchens. Gas appliances of type C are allowed (refer to current legislation and regulations in the place of installation). H072067UK0 / DT

8 ddgas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation). d d The stove or fireplace must not be used simultaneously with collective type ventilation ducts with or without extractor fan, other devices or other appliances such as: forced ventilation systems or other heating systems using ventilation to change the air. Such systems could cause a vacuum in the environment of installation even if installed in adjoining or communicating rooms. ddthe stove or fireplace must not be used: in stairwells except in buildings with no more than two apartments; in corridors for common use; in bedrooms; in bathrooms or shower-rooms..6 CAPACITy load of the floor Check the load-bearing capacity of the floor, referring to the weight of the product given in the paragraph TECHNICAL DATA. If the floor does not have a suitable load-bearing capacity, adequate countermeasures must be taken. DT Heating CAPACITy DT Check the heating capacity of the appliance by comparing the rated power given in the paragraph TECHNICAL DATA with the power required by the environment to be heated. The energy requirement may be calculated approximately by multiplying the square metres of area by the height of the ceiling; the result is then multiplied by a coefficient, which depends on the degree of insulation of the building, that is, on internal and external factors of the dwelling: --Internal factors: type of window and door frames, thickness of the insulation and walls, type of building materials, presence of stairwells, walls with extensive glazing, high ceilings, position of the rooms to be heated in relation to other adjacent heated or unheated rooms,. -- External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude,. Example of approximate calculation of the energy requirement to heat a fixed volume to 8/20 C: The coefficient that is normally used is determined according to the real conditions as they occur case by case. From 0.04 to 0.05 kw per cubic metre in a well insulated environment. From 0.05 to 0.06 kw per cubic metre in a poorly insulated environment. 3 rooms measuring 20 m 2 X (H ceiling) 2.7 m = 62 m 3 (volume) In an environment with a good degree of insulation, an average value (coefficient) of kw may be taken 62 (volume) X (kw) = 7.3 kw necessary (6300 kcal/h) Conversion kw = 860 kcal/h aaconsult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see REFERENCE STANDARDS ). aarated power being equal, products with the Multi-fire system can evenly distribute heat throughout the rooms to be heated. 8 H072067UK0 / DT

9 .8 Minimum safety distances DT Install the product respecting the safety distances from heat sensitive or flammable materials. In case of heat sensitive or flammable flooring, it is necessary to install flame-resistant protection: e.g. steel sheets, marble, tiles, etc. The minimum distances from the stove are: Fig. 6 Side wall F B Rear wall STOVE A B Side wall E D C E Floor protection Heat radiation area DT A B C D E F G Stove distance from rear wall Stove distance from side walls Area clear of flammable objects Floor protection front overhang Distance between inside edge of fireside opening and the edge of the floor protection Distance from the outlet to the rear non-inflammable wall; for walls;see the technical documentation supplied with the smoke flue for flammable or heat sensitive walls. Distance between stove and smoke outlet The minimum safety distances are shown in the table TECHNICAL DATA. The flue pipe must respect the minimum distances from building materials that are heat sensitive or flammable (cladding, beams or wooden ceilings, etc.) as shown in the figure to the side. aathe smoke flue must be suitable for connection to a pellet stove in compliance with the relative national laws in force. aakeep any flammable products such as: wood furniture, carpets, curtains, flammable liquids, etc.. well away from the stove during operation (minimum 80 cm). aawe recommend keeping greater distances around the stove than those displayed in order to facilitate any work on the appliance and avoid overheating. Fig. 7 Fig. 8 MIN. 40 cm MIN. 5 cm* MIN. 25 cm* DT DT * = Values refer to the use of original smoke flues provided by Gruppo Piazzetta; if using other pipes for the smoke flue, see the documentation supplied with the pipes H072067UK0 / DT

10 .9 Flueway DT aathe pellet stove is not the same as other stoves. It has a forced draught of flue gas by a fan, which keeps the firebox in a vacuum and the entire flueway slightly pressurised. For this reason the flue must be completely airtight and correctly installed to ensure both trouble-free operation and user safety. The flueway must be made by specialised personnel or firms, as outlined below. The flue must be installed in such a way as to guarantee that periodic cleaning can be carried out without dismantling any parts whatsoever. Pipes should always be sealed with silicone (not cement-based sealants) or specially adapted gaskets/seals, which retain their strength and elasticity at high temperatures (250 C), and should be fixed with 3.9 mm ø self-tapping screws. aausing the relative pipe clips, fix the flue to the wall so that it does not weigh on the smoke fan. dddo not install dampers or valves that could block the passage of flue gas. dddo not connect to a flueway into which other appliances (boilers, extractor hoods, etc.) discharge fumes or vapours. Pipes and maximum usable lengths Pipes of painted aluminium-clad steel (minimum thickness.5mm), stainless steel (AISI 36) or enamelled steel (minimum thickness 0.5mm) with a nominal diameter of 80 or 00 mm (for pipes which run inside the flue m aximum diameter 50 mm) can be used. The male-female connectors must have a minimum length of 50 mm. The diameter of the pipes depends on the type of installation. The stove was designed to take 80 mm diameter pipes but, as shown in Table, in some cases the use of double-lined 00 mm diameter pipes is recommended. aalosses in pressure associated with a 90 bend can be compared to those incurred by one metre of pipe. An inspectable uniontee can be considered equivalent to a 90 bend. EXAMPLE: if installing a section greater than 4.5 m in length with 80 mm diameter pipe, calculate the maximum usable length in the following ways: If a maximum of three 90 bends are used, the maximum length of the section will be 4.5 m. TABLE PIPE LENGTH TYPE OF INSTALLATION WITH 80 mm DIAMETER PIPE WITH DOUBLE- WALLED 00 mm DIAMETER PIPE Maximum length (with three 90 bends) 4.5 m 8 m For installations more than 200 m above sea level - Obligatoire Maximum number of bends 3 4 Length of horizontal sections with minimum 3% gradient 2 m 2 m Fig. 9 Ø 00 mm STRAIGHT REDUCER Ø 80>Ø 00 Ø 80 mm If a maximum of two 90 bends are used and bearing in mind that a 90 bend can be replaced by one metre of pipe, the maximum length of the section will be 4,5 m+ m=5,5 m. TEE WITH SEALING PLUG If a maximum of one 90 bend is used and bearing in mind that a 90 bend can be replaced by one metre of pipe, the maximum length of the section will be 4, 5m+ m+ m=6,5 m. Where 00 mm diameter pipe must be used, connect it to the stove flue outlet with a 80 mm union-tee then use a 80 mm/00 mm adaptor (not supplied by Piazzetta) (Fig. 9). Fig. 20 INSULATING MATERIAL TEE DT Union-tee The use of this type of fitting must allow for the collection of condensate mixed with soot, which builds up inside the pipe. It must also permit periodic cleaning of the flue without the need to disassemble the pipes. This type of fitting can be bought at Piazzetta retail outlets together with the pipes. An example is given below of a flueway connection, which allows complete cleaning without having to disassemble the pipes (Fig. 20). TEE DIRECTION OF CLEANING Max. 2m (min. 3%) DIRECTION OF CLEANING DIRECTION OF CLEANING DT H072067UK0 / DT

11 .0 Connecting to a conventional chimney DT If you wish to use an existing chimney it is strongly recommended that you have it checked by a professional chimneysweep to ensure that it is completely airtight. The reason for this is that the smoke, because it is slightly pressurised, can infiltrate any cracks in the flue and escape into living spaces. If upon inspection you find that the chimney is not completely sound, it is recommended that you insert piping made of new material. If the existing chimney is wide enough we recommend a pipe with a maximum diameter of 50mm. It is also recommended that you insulate the chimney flue (Fig. 2-22). Fig. 2 CHIMNEY STACK Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended for connection to the flueway, since they are sized to fit the flue outlet of the appliance. WITH DAMAGED FLUE Ø 50 mm MAX Other pipes may be applied after adaptation and checking of the compatibility of the coupling, taking into account that the pipes and bends must be made in compliance with current regulations. In this case, however, Gruppo Piazzetta S.p.A. only guarantees trouble-free operation for parts that it manufactures and that are used according to specifications. TEE PIPE INSERTION INSULATING MATERIAL If the connector has to pass through partitions or walls of inflammable or heat-sensitive materials, or through load-bearing walls, create an insulating barrier equal to or greater than 0cm around the connector using mineral-based insulating material (rock wool, ceramic fibre) with a nominal density greater than 80 kg/m 3. Ø 80 mm INSPECTION WINDOWS DT If the connector has to pass through non-flammable partitions or walls, create an insulating barrier equal to or greater than 5cm around the connector using mineral-based insulating material (rock wool, ceramic fibre) with a nominal density greater than 80 kg/m 3. Fig. 22 CLOSING FLANGE Check that the connection to the flueway is gas/smoke-tight, since the appliance operates in a vacuum. Check that the pipe does not penetrate too far into the flueway, thereby choking the pipe for the passage of smoke and combustion gases. aaensure that all installation work is carried out to professional standards. SEALING FLANGE IN STAINLESS STEEL OR ALUMINIUM FRESH AIR INTAKE WITH NON-CLOSABLE GRILLE DT H072067UK0 / DT

12 . Using an external flue DT An external flue can be used provided it complies with the following requirements: --use only insulated stainless steel pipes (double-lined) fixed to the outside wall of the building (Fig. 23); --there must be an inspection opening at the base of the flue to permit periodic checks and maintenance; --the flue must be fitted at the top with a chimney stack with downdraught cowl, also ensuring compliance with the safety distance from the roof ridge as outlined in the section entitled CHIMNEY STACK. aaensure that all installation work is carried out to professional standards. Fig. 23 d FRESH AIR INTAKE WITH NON-CLOSABLE GRILLE DT Prevention of domestic fires DT The product must be installed and used in compliance with the manufacturer s instructions and European and national standards as well as local regulations. aawhen a flue pipe passes through a wall or a ceiling, special installation methods must be applied (protection, thermal insulation, distances from heat-sensitive materials, etc.) See the paragraph CONNECTION TO THE FLUEWAY. It is also recommended that all elements made of combustible or inflammable material, such as beams, wooden furniture, curtaining, flammable liquids, etc. be kept outside the heat radiation range of the stove and at a distance of at least 00 cm from the heating block. For other information, see the paragraph SAFETY DISTANCES and CONNECTION TO THE FLUEWAY. The flue pipe, chimney stack, chimney and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least twice during the seasonal period from the lighting of the stove and during its use. When the stove has not been used for some time it is advisable to carry out the checks mentioned above. For further information, consult a chimneysweep. Only use recommended fuels (See section FUEL ). 2 H072067UK0 / DT

16 3.0 FUEL The wood pellet is obtained by pressing wood sawdust left over from the working of natural dried wood. The typical small, cylindrical form is obtained by passing the material through a die. Thanks to lignin, a natural element which is released during the pressing of the raw material, the pellets acquire a good consistency and compactness without requiring treatment with additives or caking agents. There are various types of pellet on the market with qualities and characteristics that vary depending on the processes they have undergone and the type of wood used in their production. Since the characteristics and quality of the pellet considerably affect stove performance, efficiency and proper operation, we recommend that you use high-quality pellets. Gruppo Piazzetta S.p.A has tested and programmed its stoves and can ensure best performance and trouble-free operation using pellets with the following specific characteristics: Pellet characteristics Components natural pure wood pellet Length, approx mm Diameter, approx mm Apparent density, approx. 650 kg/m 3 Specific weight, approx. >.0 kg/dm 3 Net heat value, approx. 5 kwh/kg Moisture content, approx. <8% Residual ash, approx. <0.5% N.B.: the above data refer to beech/fir wood pellets Choosing other and unsuitable pellets --obstructs the grate and flue gas pipes; --increases fuel consumption; --reduces efficiency; --means that proper stove operation cannot be guaranteed; --causes dirt to build up on the glass; --leaves particles which have failed to burn and heavy cinders. DT The presence of moisture in the pellets increases their volume and causes them to split which in turn causes: --malfunction of the fuel-loading system; --inefficient combustion. Pellets should be stored in a sheltered, dry place. To use good quality pellets with dimensions and heat-producing properties other than those recommended above, it will be necessary to change the stove operating parameters. aathis customisation of stove settings must be carried out at a Gruppo Piazzetta S.p.A. Service Centre or by specially qualified personnel authorised by Gruppo Piazzetta S.p.A. aausing pellets that are out of date or not in conformity with the manufacturer s recommendations not only damages the stove and jeopardises its performance, but can render the guarantee null and void and relieves the manufacturer of all liability. To ensure trouble-free operation: DO NOT use pellets with dimensions other than those recommended by the manufacturer. DO NOT use poor quality pellets containing sawdust, bark, maize, resins or chemical substances, additives or adhesives. DO NOT use damp pellets. 4.0 PREPARING FOR INSTALLATION DT To prevent accidents or damage to the product we recommend the following: --unpacking and installation must be carried out by at least two people; --every operation involving movement of the product must be carried out with the proper tools in full compliance with current safety regulations; --the packaged product must be kept in the position according to the directions shown by the diagrams and notices on the pack; --if ropes, straps or chains are used, ensure that they are able to take the weight of the pack and that they are in good condition; --use slow continuous movements when moving the pack to avoid jerking the ropes, chains, etc.; --do not tilt the package excessively to avoid toppling; --never stand in the vicinity of loading/unloading equipment (forklift trucks, cranes etc). aaunpack the product being careful not to damage or scratch it, take the accessories pack and any pieces of polystyrene or cardboard used to wedge moveable parts etc. out of the stove firebox. Keep packaging (plastic bags, polystyrene, etc.) out of reach of children, since it could be a potential source of danger, and dispose of according to local regulations. 6 H072067UK0 / DT

17 5.0 INSTALLATION DT Pursuant to current regulations on the safety of electrical equipment, you must contact a Piazzetta After-Sales Service Centre or a qualified electrician for all and any work connected with installation, maintenance or servicing that involves access to electrical parts. Cladding Having completed assembly of the stove and installed any external room thermostat, proceed with assembly of the stove cladding, referring to the ceramic cladding instruction booklet provided with the stove. DT MULTIFUOCO system DT Thanks to Piazzetta technology and R&D, this pellet stove offers the advantages of the Multifuoco system, a system EXCLUSIVE to and PATENTED by Gruppo Piazzetta S.p.A., a true innovation in the field of pellet stoves. Fig. 24 The Multifuoco system revolutionises all methods of heat circulation currently in use in pellet stoves: the heat produced by the firebox is not only circulated from the lower part of the stove into the room, but hot air can also be ducted via Ø 75 mm hoses to adjoining rooms (Fig. 25). This exclusive floor-standing heat distribution system offers notable advantages: even spread of temperatures (Fig. 24). The hot air produced is propelled by two fans and distributed via the grille at the back of the stove. Fig. 25 DT DT The grille has two deflectors (Fig. 26) to deviate the flow of air as it comes out of the front part. To deflect the heat current in the desired direction simply adjust the angle of the deflectors using the lever (A) supplied (Fig. 27). Fig. 26 Instructions for ducting hot air The ventilation kit which expels heat into the atmosphere is equipped with two Y shaped elements (one per motor) which allow the air flow to be doubled up, directing it via a flexible pipe to the back of the stove from where it can be directed into other environments. aado not install more than two Y-elements in the stove otherwise there could be problems of overheating.

18 The following are some examples of installation of the stove and examples of warm air ducting systems for heating. These examples are merely indicative, performance is optimal with 7.5 cm diameter pipes coated as described in the subsection Wall and ceiling ducting systems and with a maximum total length of pipe of 6 meters. This length is given by the sum of the individual lengths of pipes for each fan, plus the elbows and Y elements and is subject to checks of the dimensions and the insulation classification of the environment to be heated. aaevery bend and/or Y connector is comparable to metre of straight ducting. The examples show ducting system of the two fans. Each figure represents only one example of the many possible solutions. To achieve some of the proposed solutions it is necessary to use a flexible pipe with a diameter of 75 mm, air outlet vents and Y elements, none of which are supplied. Fig. 27 Fig. 28 A Solution - Fig. 28: The stove is installed in the room which is to be heated with, as standard, the heat directed to the front only (Fig. 28). Solution 2 - Fig. 29: The stove is installed in the room which is to be heated with the heat directed to the front by one fan. In addition, a second fan directs heat to the rear allowing for a second room to be heated. aafor the example shown in Figure 29 with single ducting, it is necessary to use a non-closable vent. Fig. 29 Solution 3 - Fig. 30: The stove is installed in the room which is to be heated, with the heat channelled in three directions. Using a Y element, one fan can propel the heat in two directions. The other fan will only have a front outlet. aafor the example shown in Figure 30, you can install an outlet with closure for the shortest section allowing for some of the air to be released, without ever closing completely to prevent overheating. Fig H072067UK0 / DT

19 Solution 4 - Fig. 3: Extending the previous solution with the appliance installed in the room to be heated and heat directed to the front and rear of the appliance with doubling-up using a second Y element at the rear as shown. aafor the example shown in Figure 3, you can install an outlet with closure for the shortest section allowing for some of the air to be released, without ever closing completely to prevent overheating. Fig. 3 Wall and floor ducting - Fig. 32 / 35 For efficient ducted heat distribution: --Lag the hose with a 2 cm thick insulation (e.g. mineral fibre, ceramic fibre, rock fibre) to limit heat loss and to guarantee a sufficiently warm air temperature. --The insulation must have a specific weight equal to or more than 50 kg/m³ with working temperature limit of at least 250 C. Thermal conductivity λ (00 C) 0,050 W/mK. --Material with code AGI Q32 or DIN 8895 is allowed for thermal insulation. aaif the insulating material is not enclosed under the floor or within the walls, it must be fixed to the surface with suitable fastenings at intervals of 30 cm. A few examples of how the hose can be installed in walls or floors are given to the side. Fig. 32 Fig. 33 DT Fig. 34 Fig. 35 DT DT DT Hot air outlet vent radiation area (mm) - Fig. 36 A safety area must be ensured around the hot air outlet vent within which there must be no flammable objects (furniture, carpets, curtains, etc.) or heat sensitive materials (wood, plastic, etc.). The diagram to the side shows the measurements for this safety area, which includes 600 mm from the upper edge of the vent. aaif the floor is flammable, the hot air outlet vents must be located at least 200 mm from the floor.

21 5.4 INSTALLING the Y connector (optional) DT The ducting of heat to adjoining rooms is at the user s discretion according to requirements. Fig. 43 FAN 2 FAN The Y connector, designed to double hot air delivery, may be fitted onto one or both fans at the time the stove is installed. If just one Y connector is used, it is more convenient to fit it onto the right fan (as seen from the rear). If two Y connectors are to be used, first work on the left fan and then on the right (as seen from the rear fig. 43). To install, proceed as follows: --remove the side ceramic panels and the rear panel of the stove; --uncoil the hose from the appropriate fan outlet by loosening the clip that holds it in place (Fig. 44); --cut off approx. five cm of hose (Fig. 45); Fig. 44 Fig. 45 DT DT DT fit the hose to the Y connector using the clip provided in the kit (Fig. 46); --fit the Y connector to the fan outlet using the screws provided in the kit (Fig. 47); Fig. 46 Fig. 47 DT DT fit the second hose to the Y connector using the clip provided in the kit (Fig. 48); --repeat steps 2 6 for the other fan if two Y connectors are being used; --remove the knockout from the rear panel and insert the ducting through the hole that has been created (Fig. 49); Fig. 48 Fig. 49 DT DT refit the rear panel and the side ceramic panels; --move the stove closer to the wall (Fig. 50) and, using the clips provided in the kit, fix the two hoses to the walled ducting fittings (Fig. 5); --put the stove in its final location, complying with the minimum safety distances (see section MINIMUM SAFETY DISTANCES ). Fig. 50 Fig. 5 DT DT H072067UK0 / DT

22 6.0 USE DT Do not use the stove as a cooking appliance. Ensure that the room in which the stove is installed is sufficiently well ventilated (fresh air intake). Ensure that all joints in the flue are hermetically sealed using a silicone- (not cement-) based sealant which is resistant to temperatures of up to 250ºC and which shows no sign of deterioration. Check (or have checked) regularly that the flue is clean. Under no circumstances use fuels other than pellets. Remove any deposits of unused pellets left by failed ignition before restarting the stove. aaduring operation some parts of the stove (door, handle, controls, ceramic parts) can reach high temperatures. Take great care and all the necessary precautions, especially in the presence of children, the elderly or disabled and pets. aakeep any inflammable object well away from the stove while it is in use (MINIMUM 00) cm from the front panel). aawhile in use the door must remain closed and the glass must be present and intact. The removal of the protective grille inside the pellet hopper is strictly prohibited. If replenishing with pellets while the stove is lit, ensure that the bag does not come into contact with any hot surfaces. DT Loading the pellets DT To load the pellets into the hopper it is advisable to tear off the edge of the sack and empty the sack directly into the hopper. This makes filling easier and avoids pouring pellets on top of the stove. aado not allow sawdust to accumulate on the bottom of the hopper. aado leave leftover pellets on top of the stove they could catch fire! Fig. 52 Fig. 53 DT DT H072067UK0 / DT

23 6.2 Remote control DT The pellet stove comes equipped with an LCD-display remote control and radio transmitter which allow you to operate its various functions. aathe remote s range can be affected by other devices which operate on a continuous radio frequency of MHz, for example radio headphones, toys, computers etc. The remote has a range of around seven metres in conditions where there is no interference from other sources. When pressing the keys to select the various functions wait for a signal from the stove that the selection has registered before selecting further functions. Or if you are in an adjoining room wait for confirmation on the remote s display. If the stove is not receiving signals from the remote try bringing the remote closer to the stove. Below are listed the various functions of the remote control s keys. Fig !

24 6.3 Lighting for the first time DT Before lighting the stove for the first time, check that the grate is properly placed and pushed towards the left. There will be odours when lighting the first few times due to the evaporation of paints and oils used during the manufacturing process. During this stage, air the room well where the stove is installed and avoid staying there any length of time since the fumes being given off could be harmful to persons or pets. The stove body should have settled down and the paints fully evaporated after having lit the stove a few times. To this end, follow the instructions given below when using the stove: --Operate at medium power for the first 5-6 hours after igniting the fuel (the expansion caused by the heat during this stage will allow the stove body to settle). --After the settling-down stage the stove must be set to operate at maximum power for a period between 6 and 0 hours, depending on the amount of paint on the stove body that must be evaporated off. The time indicated for operation at maximum power does not necessarily have to be continuous, but may be divided up into two periods separated by an interval of at least 3-4 hours with the stove shut down. At the end of the recommended period the paint will have evaporated and the stove should be used at the suitable power for normal use. If necessary the stove may be used for a further period at maximum power to ensure complete and final disappearance of all paint residue. When the hopper is being loaded for the first time the loading auger needs time to fill up; during this stage the pellets are not distributed inside the firebox and it is highly probable that the first attempt at ignition fails. In this case we advise to provide to load manually the auger screw following the instructions of the table LOADING AUGER in the PARAMETER MENU. If the alarm is activated, shut down the stove by pressing the ON/OFF key for a few moments, remove the fuel in the grate and then set the stove for a new ignition process. Dispose the not burned pellets contained in the brazier. 24 H072067UK0 / DT

After confirmation using the SET key, the remote control automatically returns to the initial display. FANS NORMAL 6.2 MULTICOMFORT DT The pellet stove is fitted with a Multicomfort function which works in conjunction with the Multifuoco System to improve heat distribution. This function allows the room temperature to be read from the stove or from the remote control, so that the Multifuoco settings can be varied according to the requirements of the rooms to be heated If the airflow from your stove has been ducted to other rooms you may read the temperature in the room where the stove is installed or in the room where the remote control is positioned. Example: your stove is installed in a small room and you are ducting the heat only from the rear of the stove (see solution in the section "MULTIFUOCO SYSTEM"). You can position the remote control in the room to which the hot air has been ducted and set the required temperature from this room. To carry out the necessary settings see the Multicomfort menu. The pellet stove is fitted with another function which allows the installation to operate with separate fans. This function allows differentiated hot air distribution from the two fans thereby fully exploiting the functionality of the Multicomfort system. Example: your stove is installed in a room and hot air is ducted from one fan to an adjoining room (see solution 2 in the section "MULTIFUOCO SYSTEM"). You can position the remote control in the room to which the hot air has been ducted and set the required temperature from this room. You can also set the fans separately, increasing or decreasing the Multifuoco airflow for the same room To set the functions, see the Multicomfort - Fans mode menu. For airflow controls see the paragraph Normal operation. H072067UK0 / DT

44 MULTICOMFORT This function is used to choose the sensor for reading the room temperature, from the stove or the remote control. To maximise the potential of the Multifuoco fan functions, read the sections MULTIFUOCO SYSTEM and MULTICOMFORT OPERATION. Function Action Display message Select the MULTICOMFORT menu Press the MENU key, with the SELECT MENU key select MULTICOMFORT and confirm by pressing the SET key. MULTI COMFORT Select the STOVE sensor or REMOTE CONTROL sensor Press the SELECT MENU key and select RRC to read the room temperature from the remote control or STOVE to read the room temperature from the stove, confirm by pressing the SET key. Once confirmed the readout FUNCTION ENABLED will appear on the display and the remote control will automatically return to the initial display. SELECT RRC SELECT STOVE aaif the MULTICOMFORT function is set on the remote control and for some reason there is no communication between the remote control and the stove, after approximately 2 minutes the reference sensor will automatically change to become the sensor installed on the stove. Remember that if the stove status is OK (power ) as a result of the room temperature reading of the remote control, it may not be OK according to the temperature reading from the actual stove which will consequently go to the power level set by the user. In all cases of lack of communication between the remote control and the stove, the emergency display is used. DT Energy Saving DT Enabling the ENERGY SAVING mode activates automatic stove start and stop at temperature values defined by the functions STOP and START. The work principle is as follows: When the temperature detected by the sensor reaches the temperature programmed by the user, the unit will automatically switch to power. (Readout OK on the display). If the temperature continues to rise until it reaches the value set on the STOP function (e.g. + 2 C above the set temperature) while the stove is running in power, the unit will turn off and go into a stand-by state. When the room temperature detected by the remote control or stove drops to the temperature value set by the user on the START function (e.g. - 3 C compared to set temperature), the stove enables a new start phase and returns to the power previously set by the user. aathe stove will re-start only when the temperatures detected by the appliance allow safe operation. If the STOP function is OFF, upon reaching the set temperature the stove will operate in the traditional way modulating power without shutting down. In a similar manner if the START function is OFF, the stove will not enable the start phase after automatic stop and will remain off. If the ENERGY SAVING has been set, the CHRONO mode only handles the start and stop of the programmed time slots. aathis function cannot be handled by the external thermostat, but only from the supplied remote control. 44 H072067UK0 / DT

This provision enables multiple channelled hot air diffusion solutions, allowing the user freedom of choice depending on adjacent rooms to be heated. Below, you will find a general and concise description of the operation of the Multifuoco System supplied. It is possible to set the Multifuoco System according to four speeds to match fan operation to the ducting solution selected. These speeds are represented by the values 0, 02, 03, 04 which appear in the row under the display and small rectangles numbered from to 4 in the row above. When switching from speed 0 to speed 04, the fan air flow increases. Once the speed of the Multifuoco System has been set, it is possible to select a higher or lower heat quantity by selecting from the five appliance power levels: P,, P5. In the same way, more heat is provided by the appliance when switching from power P to power P5. It is left to the user, based upon their own experience of using the stove, to set the Multifuoco speed and the appliance power. These selections should be based upon the ducting distance and the desired heating temperatures (by way of example, the longer the channelling route, the higher the set speed of the Multifuoco System). For each solution described in the chapter INSTALLATION in the section MULTIFUOCO SYSTEM, there is a recommendation for the Multifuoco fan speed. If SOLUTION is selected, it is recommended that fan speed 0 is selected on the control panel. If SOLUTION 2 is selected, a greater thrust of hot air will be required and in this case fan speed 02 should be chosen on the control panel. Finally, if SOLUTION 3 and SOLUTION 4 are selected, even more thrust will be required and in this case fan speed 03 or 04 should be selected on the control panel. To select the desired Multifuoco value, see the paragraph START-UP AND STANDARD OPERATION. H072067UK0 / DT
