Every appliance must have a vertical ue pipe operating by natural draught to discharge the combustion gases outdoors. The ue 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, rebox or extraction hood (Fig. 2);

- be properly sized, with constant free internal section, equal to or greater than the diameter of the ue pipe of the stove and at least 3.5 m in length (Fig. 2);

- be mainly in a vertical position with a deection from the axis of no more than 45° (Fig. 2);

- be at a suitable distance from combustible or ammable materials, ensured by an air gap or suitable insulating material (Fig. 3);

- be of uniform internal section, preferably round. Square or rectangular sections must have rounded corners with a radius of at least 20 mm and a maximum ratio between the sides of 1.5 (Fig. 4);

- the walls must be smooth if possible and without narrowing; bends must be regular and without discontinuity (Fig. 6).

d It is forbidden to make xed or mobile apertures on the ue

pipe to connect appliances other than the one to which it is already connected.

d It is forbidden to pass other air ducts or service pipes inside

the ue pipe, however large it is.

a If the ue 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.

We recommend that the ue must have a chamber for collecting solid matter and any condensate located below the connection and which may be easily inspected by means of an airtight door. (Fig. 1)

The chimney stack is a device tted 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 ue (A);

- it must have a useful outlet section (B) of not less than twice that of the ue (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 at 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 ue 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).

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:

- 6-8 metres from any buildings or other obstacles that are higher than the chimney stack;

- 50 centimetres higher than any obstacles located at a distance less than 5 metres;

- outside the reux 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.

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.

To ensure trouble-free operation the stove/rebox 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.

The airow necessary for the re may be obtained in different ways:

- through a fresh air intake direct into the room of installation (it is advisable to place the air intake behind the hearth so that the air warms up before owing into the room through the canopy grille);

- with ducting through pipes direct to the room of installation, increasing the recommended minimum free cross section by at least 15%;

- from an adjacent room to the place of installation provided this air ows freely through permanent apertures communicating with the outside.

a The 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.

d Combustion air must not be taken from adjacent rooms used

as a garage or a combustible materials store or for activities posing a re hazard.

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:

a They must not be used as a garage, store for combustible material or for activities with a risk of re. a They 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 rebox is installed of another appliance or an extractor device.

a Do not use two stoves, a rebox and a stove, a stove and a wood-red 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).

d Gas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation). d The stove or rebox 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.

d The stove or rebox 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.

Check the load-bearing capacity of the oor by adding together: the weight of the protections (lining walls), insulating materials, surround and the stove (given in the paragraph “TECHNICAL DATA”). If the oor has an unsuitable load-bearing capacity, take adequate countermeasures.

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 coefcient, 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 xed volume to 18/20° C: The coefcient 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 m2 X (H ceiling) 2.7 m = 162 m3 (volume)

In an environment with a good degree of insulation, an average value (coefcient) 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

a Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see

“REFERENCE STANDARDS”).

a Rated power being equal, products with the Multi-re system can evenly distribute heat throughout the rooms to be heated.

Type of suitable heat insulating materials. Material: mineral bre; ceramic bre; rock wool. Form: sheets; mat; shells. Specications: specic weight of at least 245 kg/m³ with working temperature limit of at least 1000°C.

Thermal conductivity

(400°C) ≤ 0,1 W/mK

Thickness: as shown in the gures in the paragraph “MINIMUM SAFETY DISTANCES”.

a If the insulating material is not lining the walls, it must be xed all over the surface of the walls with anchorage points every 30 cm.

Material coded “AGI Q132” or “DIN 18895” is allowed for heat insulation.

1.9 MINIMUM SAFETy dISTANCES

The position of the product inside the room must take into account not only the regulations, heating requirements, the shape of the installation and adjoining rooms but also accessibility and use during maintenance operations. It is therefore recommended that an area greater than the one indicated, is left around the appliance to facilitate maintenance interventions and prevent overheating problems. The walls adjacent to the product, the structure above the appliance and the oor on which the appliance rests must be in non-ammable material. Installation is allowed near heat sensitive or ammable objects as long as there is suitable insulation protection and distances are respected (for example, in the case of a wooden oor, a protective base must be used). Construction elements which are already present such as wooden beams or a counter-hood and all trims in combustible material must be positioned outside the irradiating range of the product and away from any grilles or slits from which hot air is releases. Suitable insulating material must be used.

a Keep any ammable products such as: wood furniture,

carpets, curtains, ammable liquids, etc.. well away from the product during operation (minimum 80 cm).

a The product must be installed in compliance with the

appropriate safety distances from the walls and objects Failure to comply with these indications could result in re.

Please refer to the section “TECHNICAL SPECIFICATIONS” and installation instructions for the values.

a Distance (F): for information regarding the safety distances,

installation methods, maintenance, safety and insulation, please refer to the indications provided by the ue pipe manufacturer.

a The minimum distance (F) from heat sensitive construction

elements or inammable materials must be respected along the entire length of the ue pipe (for example, cladding, walls, beams or wooden ceilings, etc.), furthermore, when a pipe passes through a wall or ceiling, particular installation methods must be applied.

a In order to ensure safety where there may be the risk of

accidental contact with the ue pipe, the external surface must be sufciently protected in compliance with regulations and instructions provided by the ue pipe manufacturer.

a The pellet stove is not the same as other stoves. It has a forced draught of ue gas by a fan, which keeps the rebox in a vacuum

and the entire ueway slightly pressurised. For this reason the ue must be completely airtight and correctly installed to ensure both trouble-free operation and user safety.

• The ueway must be made by specialised personnel or rms, as outlined below.

• The ue 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 xed with 3.9 mm ø self-tapping screws.

a Using the relative pipe clips, x the ue to the wall so that it does not weigh on the smoke fan. d Do not install dampers or valves that could block the passage of ue gas. d Do not connect to a ueway 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 1.5 mm), stainless steel (AISI 316) or enamelled steel (minimum thickness 0.5 mm) with a nominal diameter of 80 or 100 mm (for pipes which run inside the ue maximum diameter 150 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 1, in some cases the use of double-lined 100 mm diameter pipes is recommended.

a Losses 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.

- 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 4.5m+1m=5.5m.

- 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+1m+1m=6.5m.

Where 100 mm diameter pipe must be used, connect it to the stove ue outlet with a 80 mm union-tee then use a 80 mm 100 mm adaptor (not supplied by Piazzetta) (Fig. 17).

Union-tee

The use of this type of tting must allow for the collection of condensate mixed with soot, which builds up inside the pipe. It must also permit periodic cleaning of the ue without the need to disassemble the pipes. This type of tting can be bought at Piazzetta retail outlets together with the pipes. An example is given below of a ueway connection, which allows complete cleaning without having to disassemble the pipes (Fig. 18).

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 inltrate any cracks in the ue and escape into living spaces. If upon inspection you nd 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 150 mm. It is also recommended that you insulate the chimney ue (Fig. 19-20).

Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended for connection to the ueway, since they are sized to t the ue outlet of the appliance.

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 specications.

• If the connector has to pass through partitions or walls of inammable or heat-sensitive materials, or through load-bearing walls, create an insulating barrier equal to or greater than 10cm around the connector using mineral-based insulating material (rock wool, ceramic bre) with a nominal density greater than 80 kg/m

• If the connector has to pass through non-ammable partitions or walls, create an insulating barrier equal to or greater than 5 cm around the connector using mineral-based insulating material (rock wool, ceramic bre) with a nominal density greater than 80 kg/m3.

• Check that the connection to the ueway is gas/smoke-tight, since the appliance operates in a vacuum.

• Check that the pipe does not penetrate too far into the ueway, thereby choking the pipe for the passage of smoke and combustion gases.

a Ensure that all installation work is carried out to professional

standards.

An external ue can be used provided it complies with the following requirements:

- use only insulated stainless steel pipes (double-lined) xed to the outside wall of the building (Fig. 21);

- there must be an inspection opening at the base of the ue to permit periodic checks and maintenance;

- the ue must be tted 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”.

a Ensure that all installation work is carried out to professional

standards.

The hood grille has the function of allowing air to pass from inside the hood to the environment or vice versa if the Multifuoco system is installed. Warm air comes out of the hood grille with the natural convection system and it is therefore necessary to maintain the safety distances from ammable materials such as: ammable ceilings or walls, ledges/ beams, furniture, curtains, etc.. The hood grille must be installed at least 50 cm from the ceiling and with at least 30 cm safety distance to the sides.

• For the hood grille size, see the “TECHNICAL DATA” paragraph.

a Two non-closable hood grilles must be installed without

connecting them to the stove so that the warm air that has stratied inside the lining wall can ow out.

a With a ceiling over 3 metres high, two NON-CLOSABLE hood

grilles must be installed on the hood lining at a height of 30 cm from the ceiling to allow the stratied air to ow out.

Dimensions in cm

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, efciency 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 specic characteristics:

Pellet characteristics

Components natural pure wood pellet Length, approx. 10 - 30 mm Diameter, approx. 6 - 6,5 mm Apparent density, approx. 650 kg/m

Specic weight, approx. > 1,0 kg/dm

Net heat value, approx. 5 kWh/kg Moisture content, approx. < 8% Residual ash, approx. < 0,5% N.B. the above data refer to beech/r 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.

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).

a Unpack 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 rebox. 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.

Choosing other and unsuitable pellets:

- obstructs the grate and ue gas pipes;

- increases fuel consumption;

- reduces efciency;

- 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;

- inefcient 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.

a This “customisation” of stove settings must be carried out

at a Gruppo Piazzetta S.p.A. Service Centre or by specially qualied personnel authorised by Gruppo Piazzetta S.p.A.

a Using 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.

Pursuant to current regulations on the safety of electrical equipment, you must contact a Piazzetta After-Sales Service Centre or a qualied electrician for all and any work connected with installation, maintenance or servicing that involves access inside the cladding/surround or the smoke chamber.

Cladding/surround

• Having completed assembly of the stove and installed any external room thermostat, proceed with erection of the lining walls or assembly of the rebox surround.

• For Gruppo Piazzetta S.p.A. surrounds, follow the instructions enclosed with the product.

DT2011812-00

5.0 INSTALLATION

The rebox surround or lining wall must be self-supporting irrespective of the building materials and under no circumstances must come into contact with the actual stove/rebox. The surround or lining wall must also be made with non-ammable materials in compliance with standards and legislation. Two “service openings” must be made so that pellets can be loaded into the stove and for cleaning or maintenance purposes. The measurements of reference for making these openings are given below. The standard version of the appliance is with the opening for pellet loading on the right side. If it is necessary to change sides for the opening (see the paragraph “HOPPER OPENING”), both “service openings” must be 170 in height.

a It is advisable to check appliance operation before nishing erection of the lining wall.

Upon completion of the lining wall and after all the building works have been stabilised and tested, the whole installation must in any case be tested to check correct operation, following the instructions given in the booklet under the paragraph “LIGHTING FOR THE FIRST TIME”.

a Removal of the hearth surround trim and/or non-compliance with the distances when constructing the lining wall could affect correct

airow and consequently the safety of the product.

a Failure to install the two service openings according to the specied dimensions will make it difcult to carry out the maintenance of

the appliance, with the consequent risk of extended and extremely costly intervention operations.

a In the case where the appliance is installed with side smoke

extractors, the tank opening must be positioned on the side opposite the smoke extractor connector.

• 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 eld of pellet stoves.

• The “Multifuoco system” revolutionises all methods of heat circulation currently in use in pellet stoves: the heat produced by the rebox 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.

38). This exclusive oor-standing heat distribution system offers notable advantages: even spread of temperatures (Fig. 39). The hot air produced is propelled by two fans and distributed via the grille at the back of the stove.

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 ow to be doubled up, directing it via a exible pipe to the back of the stove from where it can be directed into other environments.

• 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 16 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 classication of the environment to be heated.

a Every bend and/or Y connector is comparable to 1 metre of

straight ducting.

• The examples show ducting system of the two fans. Each gure represents only one example of the many possible solutions. To achieve some of the proposed solutions it is necessary to use a exible pipe with a diameter of 75 mm, air outlet vents and Y elements, none of which are supplied.

Solution 1 - Fig. 40:

The stove is installed in the room which is to be heated with, as standard, the heat directed to the front only (Fig. 40).

Solution 2 - Fig. 41:

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.

a For the example shown in Figure 41 with single ducting, it is

necessary to use a non-closable vent.

Solution 3 - Fig. 42:

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.

a For the example shown in Figure 42, 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.

a For the example shown in Figure 43, 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.

Wall and oor ducting - Fig. 44 / 47

For efcient ducted heat distribution:

- Lag the hose with a 2 cm thick insulation (e.g. mineral bre, ceramic bre, rock bre) to limit heat loss and to guarantee a sufciently warm air temperature.

- The insulation must have a specic weight equal to or more than 50 kg/m³ with working temperature limit of at least 250°C. Thermal conductivity λ (100°C) ≤ 0,050 W/mK.

- Material with code “AGI Q132” or “DIN 18895” is allowed for thermal insulation.

a If the insulating material is not enclosed under the oor or

within the walls, it must be xed to the surface with suitable fastenings at intervals of 30 cm.

A few examples of how the hose can be installed in walls or oors are given to the side.

Hot air outlet vent radiation area (mm) - Fig. 48

A safety area must be ensured around the hot air outlet vent within which there must be no ammable 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.

a If the oor is ammable, the hot air outlet vents must be

located at least 200 mm from the oor.

• The ducting of heat to adjoining rooms is at the user’s discretion according to requirements.

• The Y-element, designed to double hot air delivery, may be tted onto one or both fans at the time the stove is installed.

• If just one Y-element is used, it is more convenient to t it onto the right fan (as seen from the rear). If two Y-elements are to be used, rst work on the left fan and then on the right (as seen from the rear g. 49).

- To install, proceed as follows:

- Fit the hose to the Y-element using the clip provided in the kit (Fig.

50).

- Fit the Y-element to the fan outlet using the screws provided in the kit (Fig. 50).

- Fit the second hose to the Y-element using the clip provided in the kit (Fig. 50).

- Repeat the above steps for the other fan if two Y-elements are being used.

- Move the stove closer to the wall and, using the clips provided in the kit, x the two hoses to the walled ducting ttings (Fig. 51);

- Put the stove in its nal location, complying with the minimum safety distances (see section “MINIMUM SAFETY DISTANCES”).

6.0 USE

• Do not use the stove as a cooking appliance.

• Ensure that the room in which the stove is installed is sufciently well ventilated (fresh air intake).

• Ensure that all joints in the ue 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 ue is clean.

• Under no circumstances use fuels other than pellets.

• Remove any deposits of unused pellets left by failed ignition before restarting the stove.

a During 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 inammable object well away from the stove while it is in use (MINIMUM 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.

DT2010035-06

DT2010348-00

6.1 LOAdING ThE PELLETS

• 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 lling easier and avoids pouring pellets on top of the stove.

a Do not allow sawdust to accumulate on the bottom of the

hopper.

a When loading pellets make sure that they do not fall out of

the pellet tank and into the insert because it may ignite upon contact with scolding hot parts.

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.

a The 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, 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 conrmation on the remote’s display. If the stove is not receiving signals from the remote try bringing the remote closer to the stove.

6.3 LIGhTING FOR ThE FIRST TIME

• Before lighting the stove for the rst time, check that the grate is properly placed and pushed towards the left.

• There will be odours when lighting the rst 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 rst 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 nal disappearance of all paint residue.

When the hopper is being loaded for the rst time the loading auger needs time to ll up; during this stage the pellets are not distributed inside the rebox and it is highly probable that the rst 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.

6.4 START-UP ANd NORMAL FUNCTIONING

• Before proceeding with lighting the stove remember:

a Check that the reside door is well closed.

• The pellet hopper must be full or contain enough fuel to run the stove for the desired time.

• 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.

• Check that you have set the correct language (see section “SETTING THE LANGUAGE”).

6.11 ThERMOSTAT

The function of the thermostat is to allow the user to program the stove so that it is switched on and off independently without the manual intervention of an operator. This thermostat allows you to select the daily, weekly and weekend programs with a maximum of 2 cycles in two different time slots.

For example: 1st cycle: from 06.00h to 09.00h. 2nd cycle: from 20.30h to 23.00h.

• In the DAY program 2 time slots established can be engaged or disabled for all days of the week.

For example: the user wants the stove to switch on the stove from 06:00 to 09:00 every day

• In the WEEK program the 2 time slots established can be engaged or disabled for all days of the week.

For example: the user wants the stove to switch on from 06:00 to 09:00 on Monday and Tuesday, but not on Wednesday, and so on.

• In the WEEK-END program the 2 time slots established can be engaged or disabled for Friday, Saturday and Sunday.

For example: the user wants the stove to switch on from 06:00h to 09:00h on Friday, Saturday, but not on Sunday.

DT2010256-00

6.13 MULTICOMFORT

The pellet stove is tted 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 airow 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 1 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 tted 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 airow for the same room To set the functions, see the Multicomfort - Fans mode menu. For airow controls see the paragraph Normal operation.

Remember that if the stove status is OK (power 1) 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.

6.14 ENERGy SAvING

Enabling the ENERGY SAVING mode activates automatic stove start and stop at temperature values dened 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 1.1 (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 1, 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.

a The stove will re-start only when the temperatures detected by the appliance allow safe operation.

If the STOP function is in OFF, upon reaching the set temperature the stove will operate in the traditional way modulating power 1 without shutting down. In a similar manner if the START function is in 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.

a This function cannot be handled by the external thermostat, but only from the supplied remote control.

If two pellets stoves of the same model are installed close to each other and the remote control beam activates both simultaneously, it is possible to modify the transmission unit when the stove has been shut down by proceeding in the following way

DT2010231-05

6.19 MULTIFUOCO SySTEM OPERATION

The pellet stove with “Multifuoco System” is equipped with one/two fans depending on the model which oversee hot air diffusion. 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 nd 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 01, 02, 03, 04 which appear in the row under the display and small rectangles numbered from 1 to 4 in the row above. When switching from speed 01 to speed 04, the fan air ow 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 ve appliance power levels: P1, …, P5. In the same way, more heat is provided by the appliance when switching from power P1 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 1 is selected, it is recommended that fan speed “01”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.

6.22 dISPOSAL OF AShES

Ash from natural (non-treated) wood burned in stoves or open reboxes is composed mainly of calcium, silicon, potassium and magnesium oxides. The ashes can therefore be used as a fertiliser for plants or in the garden, albeit not exceeding 2.6 kg per 10 m² annually.

a The ashes should be placed in a metal container with a sealed cover. The sealed container should be placed on a noncombustible

surface at a safe distance from combustible materials until the cinders have been completely extinguished.

d Only when they have been fully extinguished can the ashes be thrown away with organic waste, assuming that nails or other non-

organic material are not present.

7.6 CLEANING ThE ENAMELLEd METAL PARTS

When cleaning the enamelled metal parts of the product use a soft cloth moistened with water

d Never 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

7.7 CLEANING ThE GLASS (dAILy)

a The 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.

d Do not use any material that could scratch or spoil the glass, as scratches may develop into cracks or breaks.

DT2010093-06

7.8 REPLACING ThE wINdOw

DT2010096-04

7.11 whEN NOT IN USE

a Any cleaning or maintenance work must be carried out after the CURRENT HAS BEEN SWITCHED OFF.

The stove is tted 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 qualied persons.

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 bafe plate or internal bafe plates of the rebox and coat them using the spray paint, supplied with the kit, to prevent them from oxidising and consequently forming rust.

a If the cast-iron parts inside the rebox are not coated, rust could form. This is a natural process, which does not affect the efciency

and quality of the product.

- Clean the ue 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.
