(Fig. 1) 4 H07025240/DT2000723 – 01 DT2010539-03 1.2 Fresh air intake To ensure trouble-free operation the stove must have the necessary air available for combustion and this is provided through the fresh air intake. Fig. 2 English 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. DT2030054-00 DT2010539-03 1.3 Outside combustion air It is recommended that the stove be connected to an outside source of combustion air under certain conditions (negative pressure). To install outside air use any 2” I.D. flexible metal hose or rigid metal pipe (conduit). It must be connected around (NOT INSIDE) the combustion air inlet tube (Fig. 3). Increase the outside air pipe diameter to 3” for runs over 15 ft (4,5 m) and elevation over 4 ft (1 m). Fig. 3 2" O.D. COMBUSTION AIR TUBE aaLong runs should be avoided. Be careful not to pinch or bend the outside air pipe with too small a radius. Outside Air Pipe may be terminated flush with the outside wall but should be protected from wind and weather by a hood. aaThe outside air pipe must terminate above the maximum snow line and at least 4 ft (1.2 m) below the exhaust vent outlet. Take care not to draw cold air past water pipes that may freeze. An open mesh screen should be placed over the outside air pipe opening to prevent birds or rodents from nesting in the opening. Use an elbow or shield to prevent prevailing winds from blowing directly into the outside air intake pipe. DT2033383-00 NOTE: Mesh screen should be no smaller than 1/4” by 1/4” (6,4 by 6,4 mm). aaOutside combustion air is required for all mobile home installations and where building codes require. aaIn bedroom or bathroom installations the outside air connection is required. DT2010033-01 1.4 Installation environment Contact local building authority before installation to determine if a permit and/or inspection is required. When locating your appliance, consider the building structure to ensure the vent will not interfere with any ceiling joists, roof rafters, wall studs, water pipes or electrical wiring. It may be easier to relocate the appliance than to rework the building structure. 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. aaLocating the stove in a room with an explosive athmosphere is prohibited. 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. ddThe 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. H07025240/DT2000723 – 01 5 DT2010032-00 1.5 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. DT2011553-02 Fig. 4 REAR WALL MIN 3" MIN 4" SIDE WALL Install the product in compliance with the recommended safety distances from heat sensitive or inflammable materials and not inflammable, from load bearing and other walls and also from wooden elements, furniture, etc. The minimum distances are: -- 4” (10 cm) from the wall behind the stove; -- 6” (15 cm) from the side wall; -- 3” (8 cm) from the flue gas outlet on the rear wall in case of ceiling vent exit; -- 32” (80 cm) in the heat radiation area and from the the hot air fan outlet. 6" 4" In the case of flooring that is heat sensitive or inflammable the floor must be protected with non-combustible insulating material, e.g. sheets of steel plate, marble, tiles, etc. The floor protection must extend: -- under the product; -- a minimum of 6” (152 mm) in front of unit and beyond each side of the fuel loading and ash removal opening (4” / 10 cm from the external side of the coating). 6" FLOOR PROTECTION 32" HEAT RADIATION AREA DT2033045-00 Fig. 5 REAR WALL Connection to the flue must respect minimum safety distances from heat-sensitive structural components or inflammable materials (wood panelling, beams or ceilings, etc) shown in figures. 6" MIN 3" aaThe stove will become hot while in operation.

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 (>450°F / 230°C), and should be fixed with at least three sheet metal 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 A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT. ddDO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. ddDo not connect to a flueway into which extractor hoods discharge vapours. aaThe very hot exhaust gases may cause skin burns: keep a considerable distance away from the appliance. aaThe exhaust gases from the combustion of pellets fuel may dirty the outside of the walls. To avoid such possibility terminate the vent above the roof line. Pipes and maximum usable lenghts The exhaust pipe on all stoves is 2.95” O.D. so the stove was designed to accommodate a 3” stove pipe adaptor but the diameters of the pipes depends on the type of installation. Your installation may require the use of 4” vent as shown in Table 1. TABLE 1: CONNECTION TO FLUE PIPE - PIPE LENGTH WITH 3” DIAMETER PIPE WITH DOUBLE-WALLED 4” DIAMETER PIPE 20’ 25’ For installations more than 4000’ (1200 m) above sea level - Required Maximum number of elbows 3 3 10’ 10’ TYPE OF INSTALLATION Maximum length (with three 90° elbows) Length of horizontal sections with minimum 3% gradient aaLosses in pressure associated with a 90° elbow can be compared to those incurred by three feet of pipe. An inspectable union-tee can be considered equivalent to a 90° bend. EXAMPLE: if installing a section greater than 20’ in length with 3” diameter pipe, calculate the maximum usable length in the following ways: •If a maximum of three 90° elbows are used, the maximum length of the section will be 20’. •If a maximum of two 90° elbows are used and bearing in mind that a 90° bend can be replaced by 3’ of pipe, the maximum length of the section will be 20’+3’ = 23’. •If a maximum of one 90° elbows 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 20’+3’+3’ = 26’. H07025240/DT2000723 – 01 7 English aaThe stove requires a UL listed pellet vent. So the venting system shall be approved for pellet stoves by a certified testing Laboratory. aaPL Vent must be used for venting all Freestanding stoves. ddDo not use to vent pellet appliance these venting materials and products: Where 4” diameter pipe must be used, connect it to the stove flue outlet with a 3” union-tee then use a 3” – 4” adaptor (Fig. 8). Fig. 8 Ø 4" English Ø 3" PELLET STOVE TEE W/TEE CAP DT2033009-00 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. Single or double clean-out tees may be used. An example is given below of a flueway connection, which allows complete cleaning without having to disassemble the pipes (Fig. 9).

Framing material shall be the same as that of adjacent joist material. -- Install Black Ceiling Support from below joist level and fasten with 4 – 1.5” spiral nails or screws (Fig. 10). Alternatively, a Support Assembly may be used in place of the black celing support the support assembly fits to ceiling opening from below and is fastened to joists with 4 1.5” spiral nails or screws (Fig. 10). -- Insert first Vent section through Support and tighten the clamp screw. Additionally fasten the vent with four screw (max ½” long) through the support collar and into the vent skin. -- Install the vent section(s) atop the first. Twist lock sections together with a clock-wise turn. Before twisting, push vent sections firmly together for proper lock barb engagement. Enough twisting force must be applied to ensure that the collars will compress gasket material. -- Firestops are required where the vent penetrates a floor or ceiling. Cut a hole of the appropriate size in the ceiling/floor and install the Firestop from above or below the joist. Fasten the Firestop with nails through the corners (Fig. 10). -- Elbows may be used to offset the Vent as necessary to jog around joists or rafters. Keep use of elbows to a minimum as they reduce drafts capacity of a vent. -- Continue the Vent up through the roof line. -- Slide the Flashing over the Vent until it sits on the roof line. Slip the upper side of the Flashing base under the roof shingles. Nail the flashing to the roof with a minimum of 8 roofing nails. Seals the Flashing base with appropriate roofing mastic. -- Slide the Storm Collar down the Vent until it sits on the flashing. Apply a bead of silicone around the top of the Storm Collar. -- Extend the PL Vent at least 12” above the roof line and terminate with a PL listed Rain Cap (Fig. 11). If the Vent extends more than 6’ above the roof penetreation, Roof Brace Poles and a Roof Brace Band must be used to provide lateral support. In geographical regions experiencing sustained low ambient temperature is recommended to enclose exterior vents below the roof line. This help reduce condensation, soot accumulation, and poor drafting. -- Set the Rain Cap onto the top Vent section and twist lock it to the top Vent section (Fig. 11). -- Where the vent system penetrates the air/vapour barrier, the barrier must be sealed to the ceiling support or firestop.

Using this kind of installation the pellet stove is able to draft naturally without exhaust blower operation (failure), reducing the probability of burn-back and back-drafting. Fig. 12 aaCheck that the connection to the flueway is gas/smoke-tight, since the appliance operates in a vacuum. MASONARY MUD THIMBLE •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 (Fig. 12). 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, a relining of the chimney with either PL vent or single wall stainless steel pipe may be necessary to bring the chimney into compliance. If the existing chimney is wide enough we recommend a pipe with a maximum diameter of 6”. Put attention: some areas require that a liner must be always installed to the top of the flue, as shown in figure even if the existing chimney is in compliance (Fig. 13). •When chimneys are relined, a chimney chase cap that reduces the outlet of the chimney to the size of the liner is required. Extend the exhaust vent above the chimney chase cap and finish it off with a rain cap. A single wall liner may need to be insulated to maintain adequate exhaust temperatures in the vent system. PL ADAPTER VENT TEE (T) DT2033037-00 Fig. 13 aaOutside Chimneys frequently are difficult to keep warm: it is recommended that you insulate the liner. MASONARY MUD THIMBLE PL ADAPTER •Venting into the side of an existing masonry chimney must be done through a masonry thimble. When wall penetration is necessary to access a masonry chimney, use a listed PL vent wall thimble (Fig. 12-13). •When venting into a Class A steel chimney, (Fig. 14), use an appropriate PL Vent adapter. VENT TEE (T) aaStrictly observe the PL Vent manufacturer’s safety specifications. aaThe minimum clearance required between the PL Vent and combustible material is 3”.

When installing as a hearth mount stove into a fireplace the unit must either be relined, terminating above the chimney chase top, or positively connected to the existing chimney system using a block off plate (Fig. 15-16). An approved flex liner of PL vent must be used. Put attention: some areas require that a liner must be always installed to the top of the flue, as shown in figure 16. aaA chimney system with known drafting problems may require a liner, which may also need to be insulated to keep vent system warm in cold chimney environment. POSITIVE BLOCK OFF PLATE aaA cap shall be installed on the chimney to keep out rain. aaStrictly observe the PL Vent manufacturer’s safety TEE specifications.

Also the minimum vertical run of 5 feet (1,5 m) ensures the ventilation of the exhaust in the event of a power failure, and allow for easier cleaning through cleanout on tee. aaCertain local code restrictions may apply. Check with Local Officials first before installing. aaStrictly observe the PL Vent manufacturer’s safety specifications when using wall pass through. aaDouble wall PL vent requires a minimum of three inch (3”) clearance to combustibles and the use of listed wall thimble, fire stop or English roof flashing where applicable. aaDo not place joints within wall pass-throughs. aaEnsure that all installation work is carried out to professional standards. DT2012157-00 1.12Venting: termination requirements In determining optimum vent termination, carefully evaluate external conditions especially when venting directly through a wall. Since you must deal with odors, gases, and fly ash, consider aesthetics, prevailing winds, distances from air inlets and combustibles, location of adjacent structures and any code requirements. •Exhaust must terminate above combustion air inlet elevation. •Do not terminate vent in any enclosed or semi-enclosed area, (i.e. Carports, garage, attic crawl space, etc.) or any location that can build up a concentration of fumes. •Terminals must not to be recessed into a wall or siding. •When setting into place flue caps you should consider wind factors such as dominate wind directions and currents in order to avoid down draft, fly ash and/or smoke.

Serial port DB9 BLACK BROWN BLUE YELLOW GREEN 3.0 FUEL DT2010233-04 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 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. 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 Components natural pure wood pellet Length, approx. ¼” – 1 ¼” / (7 – 30 mm) Diameter, approx. 0.23” – 0.25” / (6 – 6.5 mm) Apparent density, approx. 40.5 lb/ft3 / (650 kg/m3) Net heat value, approx. 8000 BTU/lb / (5 kWh/kg) Moisture content, approx. < 8% Residual ash, approx. < 0,5% 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. Fig. 24 N.B. the above data refer to beech/fir wood pellets 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. DT2030346-00 4.0 PREPARING FOR INSTALLATION DT2010074-06 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. aaInstallation and assembly of the stove must be carried out by qualified personnel. H07025240/DT2000723 – 01 19 English 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. 5.0 INSTALLATION DT2010116-02 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. English 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. DT2010071-05 DT2012361-00 5.1 Multifuoco System •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. •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 3” / (Ø 75 mm) flexible pipes to adjoining rooms (Fig. 26). This exclusive floor-standing heat distribution system offers notable advantages: even spread of temperatures (Fig. 25). The hot air produced is propelled by a fan and distributed via the grille in the bottom front of the stove. Fig. 25 DT2030163-00 Fig. 26 •This grille is fitted with an adjustable flap. •To direct the outflow of hot air as required, adjust the angle of the flap by pressing on the part of it that projects (Fig. 27). Instructions for ducting the hot air •The fan kit, which propels hot air into the room, can be fitted with a Y-element which effectively allows the hot air flow to be doubled up, directing it via a flexible pipe also to the rear of the stove, from where it can then be ducted to adjoining rooms. •Some examples of possible installation are given below as well as examples of how to duct the hot air in order to heat other rooms. Such examples are given purely for demonstration purposes; best efficiency can be obtained using Ø 3” / (Ø 75 mm) coated ducting in accordance with instructions given in the sub-paragraph “Wall and floor ducting” and with a maximum total flexible pipe length of 32.8’ / (10 m). This length consists of the sum of the single lengths of flexible pipes. DT2030162-00 Fig. 27 aaIt is of fundamental importance that when ducting heat from the rear of the stove, the outlet vents near the stove or the Y-element must not be closed in order to avoid overheating. In cases where only one rear outlet from the fan is envisaged, the outlet vent must always be kept open. •The examples show the ducting. Each diagram gives just one example of the many possible solutions. DT2030310-01 20 H07025240/DT2000723 – 01 Solution 1 - Fig. 28 - 29: The stove is installed in the room which is to be heated, with the hot air directed to the front only, as when the stove arrives from the factory (Fig. 28). Alternatively the air can flow to the rear by connecting a 3” / 75 mm-diameter flexible pipe to the fan outlet (Fig. 29). In this set-up the stove heats the room where it is installed by radiation only, and heats the adjoining room through the ductwork to the rear. Fig. 28 aaFor the example shown in fig. 29 it is necessary to use an English outlet vent which is permanently open. DT2030164-00 Fig. 29 Non-closable vents 3.3’ Solution 2 - Fig. 30: The stove is installed in the room to be heated with the hot air ducted to the front and, with the installation of a Y-element, also to the rear thereby allowing the heating of a second room. A Ø 3” / (Ø 75 mm) flexible pipe with a maximum length of 32.8’ / (10 m) is connected to the fan outlet (Fig. 30). / (1 m) DT2030165-00 Fig. 30 Partially open vent aaFor the example shown in fig. 30 with single duct, the outlet vent must be partially open but never closed to avoid overheating. 32.8’ / (10 m) DT2030166-00 Solution 3 - Fig. 31: Extension of the previous solution, with the stove installed in the room to be heated and the air flow ducted to the front and the rear, but using a second Y-element to double the ducting at the rear as shown. Maximum total length of the flexible pipe 32.8’ / (10 m). (Fig. 31). Fig. 31 aaFor the example shown in fig. 31, for efficient ducting and to avoid overheating, the outlet vent closest to the Y-element must be partially open but never closed to avoid overheating. 19 .7’ /( 6m ) Partially open vent 6.5’ / (2 m) DT2030167-00 H07025240/DT2000723 – 01 21 Fig. 32 Fig. 33 DT2030168-00 Fig. 34 DT2030169-00 Fig. 35 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 11.8” / (30 cm). A few examples of how the flexible pipe can be installed in walls or floors are given to the side. DT2030170-00 Safety ducting distance - Fig. 36 When hot air is to be ducted using a Ø 3” / (Ø 75 mm) flexible pipe to adjoning rooms the minimum lenght shall not be under 4” / (10 cm) which corrisponds to the minimum distance allowed from the wall to rear of the stove. If the flexible pipes go throught combustible walls and ceilings the minimum required clearance is 1/2” / (1,3 cm). Such space if made by air is allowed but it is reccomended to fill this space with insulation (e.g. mineral fibre, ceramic fibre, rock fibre) wrapped around the flexible pipe.

Its operation and maintenance differ from the traditional wood stove. Follow these operating instructions exactly as stated to ensure safe and reliable operation. •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). •A certain amount of carbon monoxide may be produced within the stove as a by-product of combustion. All exhaust vent connections must be sealed with RTV silicone to assure a gas tight seal. Any leaks into a confined area caused by faulty installation or improper operation of the stove could produce dizziness, nausea and in extreme cases, death. •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. aaDirect contact with the stove while operating may cause skin burns. 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. Keep any inflammable object well away from the stove while it is in use (MINIMUM 32” - 80 cm) from the front panel. While 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. aaOperate this unit only with the fuel hopper lid closed. Failure to do so may result in emission of products of combustion from the hopper under certain conditions. Maintain hopper seal in good condition. DT2010035-06 DT2010730-00 6.1 Loading the pellets •When lighting your stove for the first time, or any time you have run out of Pellets, you will need to fill the hopper. Pellets are fed from the hopper to the burn pot by an auger. A high torque motor that is capable of doing serious harm to fingers drives the auger and for this reason in Piazzetta pellet stoves a protective grille inside the hopper is placed. Fig. 52 Fig. 53 ddDon’t remove the protective grill inside the pellet hopper. •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. ddDo not allow sawdust to accumulate on the bottom of the DT2030459-00 DT2030460-00 hopper. ddDo not leave leftover pellets on top of the stove – they could catch fire! ddDo not overfill hopper. aaMaintain hopper seal in good condition. H07025240/DT2000723 – 01 25 English DT2012364-00 DT2011836-01 6.2 Remote control •The pellet stove comes equipped with an LCD-display remote control and radio transmitter which allow you to operate its various functions. Fig. 54 English aaThe remote’s range can be affected by other devices which operate on a continuous radio frequency of 433.92 MHz, for example radio headphones, toys, wireless mouses 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.

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 10 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. 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. DT2012169-00 6.4 Startup and normal operation •Before proceeding with lighting the stove: Fig. 55 aaEnsure that the hearth door is well closed. aaNever use gasoline, gasoline-type lantern OF F fuel, kerosene, charcoal lighter fluid, or similar liquids to start or ”freschen up” a fire in this heater. Keep all such liquids well away from the heater wihle it is in use. aaWarning against overfiring: -- Pellets must not be fed manually into the burn pot. -- Never add additional fuel by hand. -- Do not fill the hopper with any fuels other than wood pellet. -- Accumulated un-burnt pellets in the burn pot after a failed ignition must be removed before starting a new ignition process. 09 : 53 68F 1 aaOperate unit only with hopper lid closed. Failure to do so may result in emmision of products of combustion from the hopper under certain conditions. •Check that the pellet tank is full or at least contains enough pellets for the stove to run for the desired period. •When the stove is connected to the power supply but is not yet lit, the display will show the readout OFF and in the lower half the current time, the measured temperature and the previously set power and fan settings. H07025240/DT2000723 – 01 27 English 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.

The temperature value selected 2, 4 or 6 °F (1, 2 or 3 °C ) in STOP function or selected in START function with negative values -2, -4 or -6 °F (-1, -2 or -3 °C) defines the value from which the Energy Saving mode will either increment or deduct from the room temperature set. The operating principle is as follows: when the room temperature measured by the room sensor, the remote control or the external thermostat reaches the temperature value programmed by the user, the stove automatically goes to power level 1 (readout “OK” on the display). If the room temperature continues to rise with operation at power level 1 up to the value set on the STOP function (e.g. +4 °F / +2 °C compared to the programmed temperature), the stove shuts down and goes into the stand-by mode. When the room temperature measured by the room sensor, the remote control or the external thermostat drops to the temperature value set by the user on the START function (e.g. -6 °F / -3 °C compared to the programmed temperature), the stoves starts a new ignition phase and goes back to H07025240/DT2000723 – 01 43 English The pellet stove is fitted with the Multicomfort function. This works in conjunction with the Multifuoco ventilation system to improve heat distribution. It 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 situated. the power level previously set by the user. aaThe stove only restarts when the temperatures measured on the actual stove allow its use in all safety. If the STOP and OFF functions are enabled, upon reaching the programmed room temperature, the stove will operate in the conventional way by going to power level 1 without shutting down. Likewise with the START and OFF enabled the stove does not start the startup/ignition phase after automatic shutdown and will remain off.

This system allows several solutions for the distribution of ducted hot air, so that the user has freedom of choice as regards the number of adjoining rooms which can be heated. Operation of the ‘Multifuoco System’ will be explained in general and conceptual terms below. In order to adjust the fan to suit the chosen ducting solution, three ‘Multifuoco System’ speed settings have been pre-programmed, which appear as 01, 02, 03 in the bottom line of the display and as small rectangles from 1 to 3 in the top line. There is a greater volume of air transferred by the fan passing from speed setting 01 to 03. Once the ‘Multifuoco System’ speed has been set, the user can choose a higher or lower amount of heat by selecting one of the four power settings on the stove: P1, …, P4. Similarly, there is a greater quantity of hot air produced by the stove passing from power setting P1 to P4. It is at the user’s discretion, based upon experience and familiarity in using the product, which of the ‘Multifuoco’ speed settings and which power level to choose. These choices will be based on the length of the ducting and the required room temperature (as an indication, the longer the ducting the higher the Multifuoco System speed setting). For each of the solutions described in the INSTALLATION section under “MULTIFUOCO SYSTEM”, there is a specific Multifuoco fan setting recommended. If opting for SOLUTION 1, it is best to use the control panel to select the speed setting “01”. If opting for SOLUTION 2, a higher fan speed will be required, in which case the speed setting on the control panel shall not be lower than “02”. Finally, if opting for SOLUTION 3, an even higher fan speed will be required, in which case it would be best to select the speed setting “03” on the control panel. To select the required Multifuoco setting, refer to the paragraph “STARTUP AND NORMAL OPERATION”. H07025240/DT2000723 – 01 47 DT2010994-00 6.19Safety devices aaDuring operation some parts of the stove (door, handle, ceramic parts) can reach high temperatures. English Remember to maintain the safety distances indicated previously. Be careful, take all due precautions and always comply with the instructions. If during operation smoke leaks from any part of the stove or the flue, shut the stove down immediately and ventilate the room. When the stove has cooled, check for the cause of the leak and if necessary call in specialist personnel. The stove is fitted with several safety devices to guarantee safe operation. aaThe safety devices are fitted to eliminate the risk of injury to people and pets and damage to property. Tampering or work carried out by unauthorised personnel can jeopardise this function. Possible warnings of problems Simple operating problems can usually be resolved with the help of the following pages.

The ashes can therefore be used as a fertiliser for plants or in the garden, albeit not exceeding 5.7 lb per 12 yd2 annually. aaAshes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have beeen thoroughly cooled. ddOnly when they have been fully extinguished can the ashes be thrown away with organic waste, assuming that nails or other nonorganic material are not present. H07025240/DT2000723 – 01 51 English 7.0 MAINTENANCE DT2010249-01 Pursuant to current regulations on the safety of electrical equipment, you must contact a Piazzetta Group 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. Maintenance is to be considered compulsory for correct and efficient stove operation. If maintenance is not carried out with the recommended frequency, stove performance could suffer. The manufacturer will not be responsible for stove deterioration or malfunction if due to poor maintenance. The frequency of cleaning depends on how much the stove is used and the quality of the fuel. All maintenance work (cleaning, any replacements, etc.) must be carried out when the stove is shutdown, completely cold and the supply cable disconnected. Do not use materials that could scratch or damage the glass, since scratches could become cracks. Under no circumstances use abrasive DT2010057-02 substances. DT2010089-05 7.1 Cleaning the grate and the grate support Clean the grate area periodically (approx. once every two days) and whenever the stove is to be lit: -- remove the grate baffle plate and lift out the grate; -- remove any ash or other material that may have built up, taking particular care to free any clogged holes using a sharp pointed tool; -- make sure the “ignition hole”, located on the left side of the grate, is kept clean; -- check the grate support and remove any ash. Fig. 64 Grate baffle plate Grate Ash pan DT2030814-02 aaAfter cleaning and before lighting the stove, check that the Fig. 65 IGNITION HOLE grate is correctly inserted and pushed towards the left. Refit the grate baffle plate. DT2030894-00 DT2010100-03 7.2 Cleaning the ash tray Every two days, check the ash drawer to see if it needs emptying. To dispose of the ashes, refer to the paragraph “DISPOSAL OF ASHES”. DT2010428-03 7.3 Cleaning the firebox Once a week clean the firebox as follows. -- Remove the grate baffle and draw out the grate. -- Turn the eccentric clamps to free the internal baffle. -- Lift the baffle slightly, gripping it by the two outer tabs to free it at the bottom and then turn it, bringing the bottom outwards, and remove. -- Using a vacuum cleaner remove the ash from the firebox. -- After having thoroughly cleaned the firebox, remount the internal baffle proceeding in the reverse order to above. -- Ensure that the tabs are properly inserted into the relative notches in the sides of the firebox and secure the baffle by turning the two eccentric clamps. -- Replace the grate, pushing it to the left and the grate baffle. Fig. 66 ECCENTRIC CLAMP INTERNAL BAFFLE A A DETAIL TABS aaThis type of cleaning requires a vacuum cleaner suitable for holding ash.

Fig. 69 CLEAN HOLE DT2030187-02 DT2010092-03 7.5 Cleaning the flue system Soot and Flyash: formation and need for removal. Fig. 70 The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least once every two months during the heating season to determine if cleaning is necessary. Until you have got reasonably used to the operating conditions of the stove, we recommend that this maintenance be carried out on a monthly basis. DT2031151-00 Remove the plug from the Tee and clean the pipes. Do not use a metal trush to clean this vent. Such a brush may scratch the vent liner and promote corrosion. Do not use chemical cleaners in this vent system. They do not eliminate need for manual cleaning and may be corrosive to vent materials. If necessary, particularly on the first few occasions, we recommend calling in a qualified technician. H07025240/DT2000723 – 01 53 DT2010059-03 7.6 Cleaning the ceramic cladding The ceramic cladding must first be cleaned with a soft dry cloth before using any detergent (even mild detergent). Products are available on the market which are suitable for cleaning ceramics as well as concentrated products for cleaning porcelain. These will remove oil, ink, coffee and wine stains, etc. English ddNever soak the ceramic cladding or clean it with cold water when it is still hot as the thermal shock could cause it to crack. DT2010061-03 7.7 Cleaning the enamelled metal parts When cleaning the enamelled metal parts of the product use a soft cloth moistened with water ddNever clean metallic parts using alcohol, solvents, petroleum-based products, acetones or other degreasing or abrasive substances. In the event of such substances being used, the manufacturer will not be responsible for any damage caused. Discolouration of metallic parts may be the result of misuse. DT2010062-05 7.8 Cleaning the glass (daily) aaThe glass should be cleaned when cold using ammonia-based degreasing agents and not corrosive substances such as solvents. Although it is likely that tar will build up on the glass during the lighting stage, it will burn off with the stove in full operation. If, however, the tar is left to build up over a long period it will require more effort to remove. We therefore recommend that the glass be cleaned daily before lighting the stove. ddDo not use any material that could scratch or spoil the glass, as scratches may develop into cracks or breaks. DT2010093-06 7.9 Replacing the window The stove is fitted with a 0.197” / (5 mm) thick glass panel, resistant to thermal shock up to 1382°F / (750°C); the glass can only be broken by heavy impact or misuse. Do not slam the door or hit the window. In case of breakage replace only with a Gruppo Piazzetta spare part. To replace, proceed as follows: -- wear protective gloves; -- remove the door and lie it flat; -- loosen the screws visible on the inside of the door; -- remove the frame and glass carefully; -- if the fibreglass seal and glazing bead have deteriorated, replace them; -- change the glass panel then replace the frame, tightening the screws carefully but not excessively; -- remount the door.

Replace the back cover on the remote control. The writing shown to the side appears on the display of the remote control. A feedback procedure between the remote control and the receiver starts automatically. After a few seconds the initial display returns. In other words, stove status prior to changing the batteries will be displayed. E.g.: if the stove was shut down, the display will appear as shown to the side. The new batteries must be of the same type as above; failure to comply with these instructions could cause a risk of explosion. The old batteries must be disposed of properly in compliance with the applicable laws in force. VER4 English Slide the cover off the back of the remote control and replace the batteries with new ones ensuring that the (+) and (–) directions are correct. The batteries must be of the type AAA (LR03) 1.5V. OFF 1 09 : 53 68F DT2010218-01 DT2010095-06 7.11Cleaning the fans aaAny cleaning or maintenance work must be carried out after the CURRENT HAS BEEN SWITCHED OFF. The stove is fitted with fans (smoke extractor and heating) positioned at the bottom rear of the stove. Any build-up of dust or ash on the blades can unbalance them resulting in noise during operation. It is necessary to have the fans cleaned annually. Since such an operation involves dismantling certain parts of the stove, have the cleaning carried out only by a Piazzetta Service Centre or other qualified persons. DT2010096-05 7.12When not in use When shutting the stove down for the summer, proceed as follows: -- remove all pellets from the hopper and feeding auger; -- carefully clean the grate, the grate support and the ash drawer; -- using a steel brush, clean the baffle plate or internal baffle plates of the firebox and coat them using the spray paint, supplied with the kit, to prevent them from oxidising and consequently forming rust. aaIf the cast-iron parts inside the firebox are not coated, rust could form. This is a natural process, which does not affect the efficiency and quality of the product. -- Clean the flue thoroughly: contact a professional chimneysweep for this purpose; -- clean by removing all dust, cobwebs, etc. from the area behind the inner lining panels once a year, in particular the fans; -- disconnect the power cable from the power supply; -- remove the batteries from the remote control. DT2010097-03 7.13Extraordinary maintenance The following maintenance should be carried out ONCE A YEAR and is necessary to ensure efficient and safe stove operation: -- clean the firebox thoroughly; -- clean and inspect the flue; -- check the condition of seals and gaskets; -- clean mechanical and moving parts (motors and fans); -- check electrical and electronic components. H07025240/DT2000723 – 01 55 8.0 TROUBLESHOOTING DT2011179-01 aaSome of the problems indicated below may be resolved by following the instructions. All work must be carried out when the appliance is cold and disconnected from the electricity supply (pull out the plug). English aaAuthorised qualified persons must be contacted, in accordance with current regulations, whenever it is necessary to work on parts inside the cladding or the firebox in order to resolve the problem. It is therefore recommended that only “Gruppo Piazzetta S.p.A.” authorised Service Centres be contacted. Whenever authorised Service Centre personnel carry out work, they must show an identity card issued by Gruppo Piazzetta S.p.A. on which the following are printed: name of the Service Centre, stamp and signature of the company and the period of validity of the actual document. aaUnauthorised tampering with the appliance or the use of other than original spare parts not only creates situations of risk for operator safety, but invalidates the warranty and relieves the manufacturer from all liability.
