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. Fig. 13 English 1.4 Fresh air intake - Fig. 12÷15 The stove/fireplace must have the necessary air available to ensure proper combustion. - Make sure that the room in which the stove/fireplace is to be installed has an air intake of at least the size indicated in the paragraph “TECHNICAL DATA”. - The fresh air intake may be protected by an external grille provided it does not reduce the minimum section of the recommended airflow and is in a position whereby it cannot be obstructed. DT2030193-00 Fig. 14 DT2030194-00 Fig. 15 The installation of a wood-burning appliance in a bedroom, bath or shower room or in any room where another heating system not equipped with its own air supply (fireplace, stove etc.) has already been installed is forbidden. The room or rooms adjacent to that where the appliance is to be installed must conform to the following requirements: It must not be used as a car bay, a store for combustible material, nor for any activity which carries a risk of fire. It must not be pressurised relative to normal atmospheric pressure as a result of the draught created by a prior installation of an open fire or of an extractor system. DT2030195-00 In the same location do not install two stoves, a stove and a fireplace, a stove and a wood-burning range etc, since the draught from one device can interfere with the draught from another. - The use of equipment adapted for cooking food with non-extractor hoods is permissible only in rooms to be used as kitchens. - Equipment using gas type C is permitted (refer to regulations in force in the place of installation). 7 SUPERIOR ® English Equipment using gas type B is not permitted (refer to regulations in force in the place of installation). Using the stove or flue simultaneously with shared ventilation systems is not permitted, whether with or without extractor fans. Similarly the use of other devices or equipment, such as air-conditioning systems or other heating systems which use fans to circulate air, is not permitted. These devices can cause the atmosphere around the stove to become pressurised even if installed in adjacent, communicating rooms. 1.6 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, for example, by using a sheet metal plate to distribute the load. 1.7 Heating capacity 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: a) 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, … b) 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 18/20° 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 20m2 X (H ceiling) 2.7m = 162 m3 (volume) In an environment with a good degree of insulation, an average value (coefficient) of 0.045 kW may be taken 162 (volume) X 0.045 (kW) = 7.3 kW necessary (6300 kcal/h) Conversion 1kW = 860 kcal/h Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see “REFERENCE STANDARDS”). Rated power being equal, products with the Multi-fire system can evenly distribute heat throughout the rooms to be heated. 8 SUPERIOR ® PareteRear posteriore wall B B STOVE STUFA E In the case of flooring that is heat sensitive or inflammable the floor should be protected (using for example sheets of steel plate, marble or tiles).

These should be attached with 3.9mm-diameter self-threading screws. DT2030335-00 MIN 40 cm The pellet stove is not the same as other stoves. The smoke is propelled by a fan which keeps the combustion chamber pressurised and the entire flue system slightly pressurised. For this reason the flue must be completely airtight and correctly installed to ensure both trouble-free operation and user safety. MIN 40 cm 1.9 Flue system - Fig. 19-20 DT2030336-00 The installation of flaps or valves which might block the passage of the smoke is not permitted. The installation of other devices (boilers, extractor hoods etc) which might release fumes or vapours into the flue system is not permitted. 9 SUPERIOR ® English Pipes and maximum usable lengths Pipes of aluminium-clad painted steel (minimum thickness 1.5mm), stainless steel (Aisi 316) or enamelled steel (minimum thickness 0.5mm) with a nominal diameter of 80 or 100mm (for pipes which run inside the flue maximum diameter 150mm) can be used. The male-female connectors must have a minimum length of 50mm. The diameter of the pipes used depends on the type of installation. The stove was designed to take 80mm-diameter pipes but, as shown in Table 1, in some cases the use of double-lined 100mmdiameter pipes is recommended.

DT2030337-00 Fig. 20 EXAMPLE: If installing a section greater than 4.5m in length with 80mm-diameter pipe, calculate the maximum usable length in the following ways: - If in the section to be fitted a maximum of three 90° bends are used, the maximum length of the section will be 4.5m. - If in the section to be fitted a maximum of two 90° bends are used and bearing in mind that a 90° bend can be replaced by one meter of pipe, the maximum length of the section will be 4.5m+1m=5.5m. - If in the section to be fitted a maximum of one 90° bend is used and bearing in mind that a 90° bend can be replaced by one meter of pipe, the maximum length of the section will be 4.5m+1m+1m=6.5m. Where 100mm-diameter pipe must be used, connect it to the stove’s exhaust outlet with a 80mm T-connector then use a 80mm-100mm adaptor (not supplied by Piazzetta) (Fig 19).

It must also permit the periodic cleaning of the flue without the need to dismantle the pipes. This type of connctor can be bought at Piazzetta outlets together with the pipes. Outlined below is an example of a set-up which can be cleaned entirely without the need to dismantle the pipes (Fig 20). 10 SUPERIOR ® Fig. 21 Chimney stack COMIGNOLO Tee RACCORDO A T For connection to the chimney the use of Piazzetta’s own pipes and bends is recommended - the stove’s outlet is the right size to connect to these. Other types of pipe can be used, provided that they are suitable or that the compatibility of the connecting sleeve can be verified. Bear in mind also that pipes and bends must be constructed according to existing regulations. In such cases however Gruppo Piazzetta S.p.A guarantees the proper functioning of the stove only where its own equipment has been employed in accordance with its own instructions. CON CANNA FUMARIA With damaged flue NON INTEGRA DI INSERIMENTO Pipe insertion UN TUBO ø 80 mm The connection to the flue system must respect the 40cm minimum safety distance from objects which are sensitive to heat and from inflammable materials (wooden veneers, beams or ceilings etc). (See figures 17-18) - If the connector has to pass through partitions or walls constructed from inflammable or heat-sensitive materials, or through weight-bearing walls, you must introduce: an insulated barrier equal to or greater than 10cm around the connector using a mineral-based insulating material (rock wool, ceramic fibre) with a nominal density greater than 80kg/m3 English 1.10 Connecting to a conventional chimney - Fig. 21-22 If you wish to use an existing chimney it is strongly recommended that you have it checked by a professional chimney-sweep 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 system 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 150mm. It is also recommended that you insulate the chimney flue (Fig. 21-22).

G SMOKE SENSOR N L POWER DT2030072-00 14 SUPERIOR ® DT2010233-00 3.0 FUEL Choosing pellets different to those stipulated: - obstructs the burner and flue ducts - increases fuel consumption - reduces efficiency - cannot guarantee the stove’s proper functioning - causes dirt to build up on the glass - leaves particles which have failed to burn and heavy cinders. There are various types of pellet on the market with qualities and characteristics which vary depending on the processes they have undergone and the type of wood used in their production. Since the pellet’s characteristics and quality affect to a considerably degree the stove’s performance, productivity and proper functioning we recommend that you USE high-quality pellets. The presence of dampness 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 sealed, dry place. Gruppo Piazzetta S.p.A has tested and programmed its stoves and can promise optimum performance and trouble-free functioning using pellets with these specific characteristics: • Material: wood • Length: not greater than 30mm • Diameter: 6-6.5mm • Inferior heat energy: 5kWh/kg • Humidity: not greater than 8% • Residual ash: 0.34% English The pellet stove has been designed to burn only wood in pellet form. 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 a process similar to wire-drawing. 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. If you wish to use good-quality pellets with different dimensions and heatproducing properties to those stipulated you will need to alter the operating parameters of the stove. This “customisation” of the stove’s settings must be carried out at one of Gruppo Piazzetta S.p.A.’s Centres for Technical Assistance or by specially qualified personnel authorised by Gruppo Piazzetta S.p.A. Using out of date pellets or those which do not conform to the manufacturer’s stipulations damages the stove and compromises performance as well as can nullifying the guarantee and excusing the manufacturer from his responsibilities. To assure trouble-free operation: DO NOT use pellets with dimensions different to those stipulated by the manufacturer. DO NOT use pellets which are out of date or which contain loose sawdust, resins, chemical substances, additives or caking agents. DO NOT use damp pellets. DT2030346-00 DT2010074-00 4.0 BEFORE UNPACKING YOUR PRODUCT During operation, some parts of the stove (door, handle, display, ceramic parts) can reach high temperatures. Therefore take due precautions, above all in the presence of children, elderly and disabled persons and pets. In order to avoid accidents or damage to the product, the following recommendations are made: • 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 orientation of the packaged product must conform to the directions given in the diagrams and notices on the package. • If cables, straps or chains are used, ensure that they are able to take the weight of the package and that they are in good condition. • While moving the package use slow continuous movements to avoid tearing cables, chains etc. • To avoid toppling do not lean the package excessively. • Do not stop in the path of loading/unloading equipment (cradles, cranes etc). 15 SUPERIOR ® DT2010075-00 English 5.0 INSTALLATION External pressure switch • The stove is equipped with an external socket for measuring the air pressure in the flue.

For the first few days running at medium power is recommended, to allow all components and mechanical parts a running in period. DT2040001-00 Upon first ignitions certain odours may be given off due to the evaporation of paint or grease. To alleviate the problem merely air the room, thus avoiding the prolonged exposure which may render these emissions harmful to people or animals. When the fuel tank is loaded for the first time the fuel-loading chute has to fill up; during this period the pellets will not be fed into the combustion chamber. 18 SUPERIOR ® English 6.3 Startup and normal operation Before proceeding with the ignition remember: ensure that the furnace door is well closed; • that the fuel tank is full or at least contains enough fuel to run for the desired period.

It is to be opened only when the stove has shut down and cooled for the carrying out of maintenance. 6.8 Removing the ash The ash drawer must be emptied regularly. The ashes must never reach the level of the burner’s supporting arm. The ashes must be put in a metal container with a sealable lid. Until the ashes are definitively extinguished, the container must be placed on a non-combustible surface or on the ground and be kept well away from combustible material. Ashes can conceal burning embers for long periods!!! 32 SUPERIOR ® DT2010111-01 7.0 MAINTENANCE 7.1 Cleaning the burner and the burner support - Fig. 31 If the flame assumes a reddish colour or becomes weak, accompanied by black smoke, it means that there are deposits of ash and other substances which are impeding the correct functioning of the stove and which should be removed. Every two days, remove the burner by simply lifting it out of its position. Then clean from it any ash or other material which may have been allowed to build up, paying particular attention to free up any blocked holes with a pointed implement (fig 31). This operation should be carried out at every startup, especially if pellets other than those supplied by Piazzetta have been used. The intervals between cleaning should be dictated by the regularity of the stove’s use by the choice of fuel. It is always worthwhile checking the burner’s support freeing it of any ash. English All maintenance work (cleaning, replacing parts, etc…) should be carried out when the stove has been extinguished and allowed to cooled. Furthermore, do not in any circumstances use abrasive substances. DT2010057-00 Fig. 31 DT2030124-00 Before lighting the stove ensure that the burner is pushed back towards the shield. 7.2 Cleaning the ash drawer Every two days, check the ash drawer to see if it needs to be emptied. For the removal of ash see section 5.8. Fig. 32 7.3 Cleaning the combustion chamber - Fig. 32-33 The combustion chamber should be cleaned once a week as follows: • Remove the internal shield raising it gently and using the flaps as handles, then rotate it and tilt it in order to slide it through the mouth of the combustion chamber (fig 32, 33). • Use a vacuum cleaner to remove any ash acccumulated in the combustion chamber. • Having cleaned the chamber thoroughly replace the parts in reverse order paying particular attention to the positioning of the internal shield: it should sit snugly beside the catches on the interior of the chamber (the two catches should remain in front of the shield). This type of cleaning requires a vacuum cleaner suitable for holding ash. DT2030126-00 Fig. 33 DT2030127-00 33 SUPERIOR ® English 7.4 Cleaning the smoke chamber - Fig. 34÷38 Every year, clean the smoke chamber as follows: • Remove the screws which hold the exhaust outlet’s hatch in place, then raise it and take it out pulling it towards you (fig 34, 35). • Use a vacuum cleaner to clean any ash and carbonous deposits which can accumulate in the chamber, paying particular attention not to damage the blades of the fan (fig 36, 37). • After cleaning the chamber, thoroughly replace the hatch and if necessary replace the lining (fig 38). 7.5 Cleaning the exhaust system Until you have acquired experience of the effects on the stove of its habitual use, it is recommended to carry out this operation once a month. Remove the cap from the T-joint and clean the pipes. If necessary, at least the first few times, consult a qualified person. Fig. 34 DT2030128-00 Fig. 35 7.6 Cleaning the ceramic cover The ceramic cover should first be cleaned with a soft dry cloth before using even delicate detergents and a damp cloth. DO NOT SOAK THE CERAMIC AND NEVER USE COLD WATER WHEN IT IS STILL HOT - THE THERMAL SHOCK COULD BREAK IT. DT2030129-00 Fig. 36 7.7 Cleaning the metal parts Clean the metal parts with a soft damp cloth. NEVER CLEAN METALLIC PARTS USING ALCOHOLS, SOLVENTS, PETROLEUM BASED AGENTS, ACETONES OR OTHER GREASEREMOVING SUBSTANCES. In the case of such substances being used, Piazzetta declines every responsibility. Discolouration of metallic parts may be the result of improper use. 7.8 Cleaning the window The window in the door should be cleaned (when cold) with ammonia-based degreasing agents and not with corrosives such as solvents. Do not allow corrosive substances to come into contact with the stove’s paintwork as this will damage it. If the glass is hot, before cleaning, the door must remain open for the time necessary to allow the glass to cool. Do not use materials which might scratch or damage the glass. DT2030130-00 Fig. 37 DT2030131-00 Fig. 38 DT2030132-00 34 SUPERIOR ® 7.10 Replacing the remote control battery To change the battery proceed as follows: using a small Philips head screwdriver, remove the screw on the back of the handset. Then holding it upside down remove the back casing. Replace the battery (type A23 12V) being careful not to reverse the polarity (the battery type and polarity are shown on the back of the handset). Close the handset and dispose of the old battery in the appropriate way. 7.11 Cleaning the fans Any cleaning or maintenance operation must be carried out after the CURRENT HAS BEEN SWITCHED OFF. The stove is equipped with fans (smoke extractor and heating) positioned low down at the rear. Any buildup of dust or ash on the blades can unbalance them resulting in noise during operation. Therefore 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 Centre for Technical Assistance or other qualified persons. 7.12 When not in use When shutting the stove down for the summer carry out the following: • Remove all pellets from the fuel tank and loading system. • Carefully clean the burner, the burner support, the combustion chamber and the ash drawer. • Clean the flue thoroughly: for this contact a professional chimney sweep. • Clean all dust, cobwebs etc from the area behind the internal cover panels once a year, in particular the fans. • Remove the power cable. 7.13 Extraordinary maintenance The following operations should be carried out annually and are necessary to guarantee the stove’s efficient and safe functioning. • Clean the combustion chamber thoroughly. • Clean and inspect the flue. • Check the condition of washers. • Clean mechanical and moving parts (motors and fans). • Check electrical and electronic components. 35 SUPERIOR ® English 7.9 Replacing the window The stove is equipped with a 4mm-thick glass pane, resistant to thermal shock up to 750ºC; the glass can only be broken by a heavy impact or by improper use. Do not slam the door or bang into the window. In case of breakage replace only with a Gruppo Piazzetta replacement part. To replace proceed as follows: • Wear protective gloves. • Remove the door and lie it flat. • Unscrew the screws visible on the inside of the door. • Remove frame and glass carefully. • If the lining has deteriorated, replace it. • Change the pane then replace the frame, tightening the screws carefully but not excessively. • Remount the door. If other problems occur, consult your nearest retailer.
