.1 Single flueway or chimney - Fig. 2/6

Every appliance must have a vertical flue pipe operating by natural draught to discharge the combustion gases outdoors.

The flue must:

- comply with regulations in force in the place of installation of the appliance;

- be tight to the products of combustion, waterproof, suitably insulated, made with materials resistant to corrosion by the gases and to stress;

- be connected to just one stove, fireplace or extraction hood (Fig. 2);

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

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

- be at a suitable distance from combustible or flammable materials, ensured by an air gap or suitable insulating material;

- be of uniform internal section, preferably round. Square or rectangular sections must have rounded corners with a radius of at least 20mm and a maximum ratio between the sides of 1.5 (Fig. 3-4-

5). The walls must be smooth if possible and without narrowing. Bends must be regular and without discontinuity (Fig. 6).

It is forbidden to make fixed or mobile apertures on the flue pipe to connect appliances other than the one to which it is already connected.

It is forbidden to pass other air ducts or service pipes inside the flue pipe, however large it is.

If the flue pipe is an incorrect size or installed other than in compliance with the above instructions, Gruppo Piazzetta S.p.A. cannot be held liable for malfunctioning of the product, damage to property or injury to persons or animals.

1.2 Soot inspection - Fig. 1

- The flue 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 bends connecting to the flue must have inspection points that allow the system to be checked, cleaned and maintained.

.3 Chimney stack - Fig. 7 / 11

The flue must be fitted at the top with a device called a chimney stack, designed to aid dispersion of the products of combustion in the atmosphere. The chimney stack must comply with the following requirements:

it must have an internal section and shape the same as the flue;

it must have a useful outlet section of not less than twice that of the flue;

the part of the flue that emerges from the roof or remains in contact with the outside (e.g. in the case of an open loft), must be covered with brick or tile elements and well insulated. It must be built in such a way as to prevent the penetration of rain, snow and foreign matter into the flue and to ensure that in the event of winds from all directions and angle, discharge of the combustion products is assured (chimney stack with down-draught cowl);

any buildings or other obstacles that are higher than the chimney stack must not be too close to the actual stack Fig.8, Fig.9;

the chimney stack must be positioned in such a way as to ensure adequate dispersion and dilution of the products of combustion and outside the reflux area.The size and shape of this area differ according to the angle of inclination of the roof and it is therefore necessary to adopt the minimum heights shown in Fig.10,11;

Example: Check the slope of the roof (columnα), 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.

.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.

The air necessary for the fire may be obtained in different ways:

- Figure 12 through an external grille direct to the room of installation;

- Figure 13 with ducting through pipes direct to the room of installation, increasing the recommended minimum free cross section by at least 15%;

- Figure 14 through a communicating hole from an adjacent room to the place of installation: this system may only be used if the air flows freely from the outside through fixed apertures;

- Figure 15 from an adjacent room to the place of installation, but only if the air flows freely through apertures communicating with the outside.

1.5 Installation environment

The appliance must 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.

Do not install 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.

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;

there must be no vacuum relative to normal atmospheric pressure as a result of the contrary draught created by a prior installation of an open fire or of an extractor system;

do not install two stoves, a stove and a fireplace or a stove and a wood-burning range etc. in the same location since the draught of one device can interfere with the draught of 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);

English

equipment using gas type B is not permitted (refer to regulations in force in the place of installation);

using the stove or fireplace 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 a pressure drop in the environment of installation even if they are 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.

English

.8 Minimum safety distances - Fig. 16/18

First of all decide the exact position for installation of the stove.

Check the minimum safe distances from heat sensitive or inflammable materials, from load bearing and other walls and also from wooden elements, furniture, etc.

The minimum distances are:

A 20 cm from the wall behind the stove B 20 cm from the side wall C 80 cm in the heat radiation area and from the hot air fan

In the case of flooring that is heat sensitive or inflammable the floor should be protected with non-combustible insulating material, e.g. sheets of steel plate, marble, tiles, etc.

The minimum distances are:

D 50 cm; E 30 cm (measured from the internal corner of the door opening).

Keep any combustible product well away from the stove when it is lit (minimum distance from the heat radiation area), for example: wooden furniture, curtains, carpets, combustible liquids, etc.

It is advisable to leave more than the indicated 20 cm free at the side of the stove to facilitate any maintenance on the appliance.

1.9 Flueway - Fig. 19-20

The pellet stove is not the same as other stoves. It has a forced draught of flue gas by a fan, which keeps the firebox in a vacuum and the entire flueway slightly pressurised. For this reason the flue must be completely airtight and correctly installed to ensure both trouble-free operation and user safety.

- The flueway must be made by specialised personnel or firms, as outlined below.

- The flue must be installed in such a way as to guarantee that periodic cleaning can be carried out without dismantling any parts whatsoever.

- Pipes should always be sealed with silicone (not cement-based sealants) or specially adapted gaskets/seals, which retain their strength and elasticity at high temperatures (250°C), and should be fixed with 3.9 mm ø self-tapping screws.

Do not install dampers or valves that could block the passage of flue gas.

Do not connect to a flueway into which other appliances (boilers, extractor hoods, etc.) discharge fumes or vapours.

ipes and maximum usable lengths

Pipes of painted aluminium-clad steel (minimum thickness

1.5mm), stainless steel (AISI 316) or enamelled steel (minimum

thickness 0.5mm) with a nominal diameter of 80 or 100 mm (for pipes which run inside the flue 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.

Losses in pressure associated with a 90° bend can be compared to those incurred by one metre of pipe. An inspectable union-tee can be considered equivalent to a 90° bend.

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 a maximum of three 90° bends are used, the maximum length of the section will be 4.5m

- 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 100mm diameter pipe must be used, connect it to the stove flue outlet with a 80mm union-tee then use a 80mm 100mm adaptor (not supplied by Piazzetta) (Fig. 19).

Union-tee

The use of this type of fitting must allow for the collection of condensate mixed with soot, which builds up inside the pipe. It must also permit periodic cleaning of the flue without the need to disassemble the pipes. This type of fitting can be bought at Piazzetta retail outlets together

with the pipes. An example is given below of a flueway connection, which allows complete cleaning without having to disassemble the pipes (Fig 20).

.10Connecting 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 chimneysweep to ensure that it is completely airtight. The reason for this is that the smoke, because it is slightly pressurised, can infiltrate any cracks in the flue and escape into living spaces. If upon inspection you find that the chimney is not completely sound, it is recommended that you insert piping made of new material. If the existing chimney is wide enough we recommend a pipe with a maximum diameter of 150mm. It is also recommended that you insulate the chimney flue (Fig. 21-22).

Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended for connection to the flueway, since they are sized to fit the flue outlet of the appliance. Other pipes may be applied after adaptation and checking of the compatibility of the coupling, taking into account that the pipes and bends must be made in compliance with current regulations. In this case, however, Gruppo Piazzetta S.p.A. only guarantees trouble-free operation for parts that it manufactures and that are used according to specifications.

Connection to the flue must respect the 40cm minimum safety distance from heat-sensitive structural components or inflammable materials (wood panelling, beams or ceilings, etc). (See figures 17-18).

- If the connector has to pass through partitions or walls of inflammable or heat-sensitive materials, or through load-bearing walls, create: an insulating barrier equal to or greater than 10cm around the connector using mineral-based insulating material (rock wool, ceramic fibre) with a nominal density greater than 80kg/m3.

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

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

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

Ensure that all installation work is carried out to professional standards.

.11 Using an external flue - Fig. 23

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

- use only insulated stainless steel pipes (double-lined) fixed to the outside wall of the building (Fig. 23);

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

- the flue must be fitted at the top with a chimney stack with downdraught cowl, also ensuring compliance with the safety distance from the roof ridge as outlined in the section entitled

Ensure that all installation work is carried out to professional standards.

1.12 Prevention of domestic fires

The product must be installed and used in compliance with the manufacturer’s instructions and European and national standards as well as local regulations.

when a flue pipe passes through a wall or a ceiling, special installation methods must be applied (protection, thermal insulation, distances from heat-sensitive materials, etc.) See the paragraph “Connection to the flueway

- It is also recommended that all elements made of combustible or inflammable material, such as beams, wooden furniture, curtaining, flammable liquids, etc. be kept outside the heat radiation range of the stove and in any case at a distance of at least 1m from the heating block.

- For other information, see the paragraph “Safety distances” and “Connection to the flueway”.

- The flue pipe, chimney stack, chimney and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least twice during the seasonal period from the lighting of the stove and during its use. When the stove has not been used for some time it is advisable to carry out the checks mentioned above. For further information, consult a chimneysweep.

4.0 PREPARING FOR INSTALLATION

DT2010074-01

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. 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).

Before installing the product make sure that you have the correct equipment. 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 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.

he 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 wiredrawing. Thanks to lignin, a natural element which is released during the pressing of the raw material, the pellets acquire a good consistency and compactness without requiring treatment with additives or caking agents.

There are various types of pellet on the market with qualities and characteristics that vary depending on the processes they have undergone and the type of wood used in their production.

Since the characteristics and quality of the pellet considerably affect stove performance, efficiency and proper operation, we recommend that you USE high-quality pellets.

Gruppo Piazzetta S.p.A has tested and programmed its stoves and can promise optimum performance and trouble-free operation using pellets with the following specific characteristics:

• Material: wood

• Length: not greater than 30mm

• Diameter: 6-6.5mm

• Net heat value: 5kWh/kg

• Moisture content: not greater than 8%

• Residual ash: 0.34%

To ensure trouble-free operation: DO NOT use pellets with dimensions other than 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.

hoosing 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 other dimensions and heat-producing properties than those recommended above, you will need to alter the operating parameters of the stove. This “customisation” of stove settings must be carried out at a Gruppo Piazzetta S.p.A. Service Centre or by specially qualified personnel authorised by Gruppo Piazzetta S.p.A.

Using pellets that are out of date or not in conformity with the manufacturer’s recommendations not only damages the stove and jeopardises performance, but can render the guarantee null and void and relieves the manufacturer of all liability.

5.0 INSTALLATION

DT2010116-01

External pressure switch

• The stove is fitted with an external pipe tap for measuring the pressure (vacuum) in the flue gas outlet pipe. Authorised personnel should carry out this verification and control whilst the stove is being installed.

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.

5.1 ‘Multifuoco’ system - Fig. 25/27

• Piazzetta’s technological research and development mean that this pellet stove offers the advantages of the ‘Multifuoco’ system, a system exclusive to and patented by Gruppo Piazzetta S.p.A. and 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 hearth is circulated into the atmosphere not only from the base of the stove itself, but it can also be directed via 75mmdiameter hoses to adjoining rooms (fig 26). This exclusive heat distribution system offers many notable advantages: even temperature distribution; heating of adjoining rooms (fig 25).

• The heat produced is propelled by a fan and distributed via the outlet located on the front of the stove (fig 27).

Instructions for ducting the hot air

• The fan system which pushes hot air into the room is fitted with a Y-element, which effectively allows the air flow to be split up, directing it via a hose also to the back of the stove from where it can then be ducted into adjoining rooms.

• Below are some examples of stove installation and examples of how to duct the hot air to heat other rooms. Such examples are intended as demonstrations; optimum performance depends in each case on conditions in the room where the stove is installed and in the adjoining rooms.

It is of fundamental importance that when ducting heat from the rear of the stove, the outlets near the stove or the Yelement must not be closed in order to avoid overheating. In cases where only one rear outlet from the fan is envisaged, the outlet must always be kept open.

The examples give guidelines for ducting. Each diagram gives just one example of the many possible solutions.

ursuant 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

OLUTION 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 7.5 cm diameter hose to the fan outlet (fig. 29). In this case the stove heats the room where it is installed by radiation only, and heats the adjoining room through the ductwork to the rear.

For the example shown in fig. 29 it is necessary to use an outlet which is permanently open.

SOLUTION 2 - Fig. 30

• The stove is installed in the room to be heated with the hot air ducted to the front and also to the rear by installing a Y-element, thereby allowing the heating of a second room. A 7.5 cm diameter hose with a maximum length of 4.5 metres is connected to the fan outlet (fig. 30).

For the example shown in fig. 30 the outlet should be partially open but never fully closed to avoid overheating.

SOLUTION 3 - Fig. 31:

• Extending 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 at the rear as shown in the figure. Use a 7.5 cm diameter hose with a maximum total length of 4.5 metres (fig. 31).

For the example shown in fig. 31, for efficient ducting it is necessary to use only partially open outlets as shown

To ensure efficient ducted heat distribution:

1) lag the pipe with insulating material to limit heat loss and ensure a sufficiently high air temperature;

2) do not exceed the total maximum hose length of 4.5 m.

Below are some examples of how the hose can be installed in walls or floors (for better performance, lag the hose with suitable insulating material).

Hot air outlet vent radiation area (mm) - Fig. 36

A safety area must be ensured around the hot air outlet vent within which there must be no flammable objects (furniture, carpets, curtains, etc.) or heat sensitive materials (wood, plastic, etc.). The diagram to the side shows the measurements for this safety area, which includes 600mm from the upper edge of the vent.

5.2

Electrical connection and the room sensor connection - Fig. 37 - 38

• The stove comes with a power cable which must be connected to

a 230v/50Hz (230V/60Hz only for Japan) supply. Connection to the rear of the stove is shown in fig. 37.

• The power rating is indicated in the paragraph “Technical data” in

this booklet.

• According to law the installation must be earthed and include a

residual current circuit breaker.

• Ensure that in its normal position the power cable does not come into contact with any heated parts.

Ensure that the electrical socket is accessible also after installation of the stove.

• When installing the stove, it is necessary to connect the room sensor (provided) in the correct socket (fig. 37). The sensor can be positioned as shown in fig. 38, otherwise remove the band and uncoil the lead and then place the sensor in a spot where a more accurate room temperature reading can be obtained.

.3 Installing the external thermostat - Fig. 39 / 41

•

To connect the external thermostat use cable of the type 2x0.5mm2 secured with a PG7 cable gland to be inserted in the relative hole in the rear panel (fig. 41). Only

authorised personnel should carry out this operation.

Installation can be carried out with any type of thermostat but requires a PG7 cable gland similar to that shown in fig. 39. To connect the room thermostat to the electronic board, refer to the wiring diagram.

• When installing, insert the thermostat cable into the PG7 cable gland and then insert this in the hole in the rear panel (fig. 41). Finally connect the room thermostat terminal to the two-pin terminal on the electronic board (fig. 40).

5.4 Installing the Y-element (optional) - Fig. 42 / 50

•

Ducting of heat to adjoining rooms is at the user’s discretion.

The Y-element should be attached to the fan outlet. Proceed as follows:

1. Remove the stove rear panel.

2. Uncoil the hose from the fan outlet by loosening the clip which holds

it in place (fig. 42).

3. Cut off approx. 5 cm hose (fig. 43).

4. Fix the hose to the Y-element using the clip that was previously

loosened (fig. 44).

5. Fix the Y-element to the fan outlet using the screws provided (figs. 45

– 46).

6. Using the hose clip provided, attach a piece of hose to the second

branch of the Y-element, of sufficient length to reach the duct embedded in the wall (fig. 47).

7. Remove the knockout from the rear panel (fig. 48).

8. Replace the rear panel.

9. Move the stove closer to the wall (fig. 49) and, using the hose clips

provided, fix the hose to the duct in the wall (fig. 50).

10. Place the stove in the desired location, complying with the minimum

safety distances (see section 1.8).

•

Do not use the stove as a cooking appliance, except for the P 960 F.

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

• Ensure that all joints in the flue are hermetically sealed using a silicone- (not cement-) based sealant which is resistant to temperatures of up to 250ºC and which shows no sign of deterioration.

• Check (or have checked) regularly that the flue is clean.

• Under no circumstances use fuels other than pellets.

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

Keep any inflammable 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

6.1 Loading the pellets - Fig. 51 - 52

• 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.

Do leave leftover pellets on top of the stove – they could catch fire!

6.2 Remote control - Fig. 53

• The pellet stove comes equipped with an LCD-display remote control and radio transmitter which allow you to operate its various functions.

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, 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. Below are listed the various functions of the remote control’s keys.

6.3 Lighting for the first time

• Before lighting the stove, check that the grate is correctly inserted

and pushed towards the left.

• When lighting the stove for the first time or when it has not been used for some time, it is advisable not to operate the stove at full power immediately. For the first few days, operation at medium power is recommended to allow all materials and mechanical parts to settle. Upon first ignition certain odours may be given off due to the evaporation of paint or grease. To alleviate the problem just air the room. Do not remain in the room when there are odours, as the fumes may be harmful to people or pets.

• When the pellet hopper is loaded for the first time the loading auger has to fill up; during this period the pellets will not be fed into the firebox.

6.4 Startup and normal operation - Fig. 54

• Before proceeding with lighting the stove:

Ensure that the hearth door is well closed.

• Check that the pellet hopper 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.

•

CONTROL first 20 seconds

The extractor fan activates for a few seconds.

• START PHASE I

The fuel-loading chute is activated and starts to feed pellets into the burner (the LED on the display lights up at fixed time intervals). The pilot light ignites (the LED on the display lights up). The extractor fan starts up.

•

START PHASE II

If the lighter has triggered the combustion process, the fuel-loading auger slows down to allow a period of stabilisation and correct combustion of the pellets in the subsequent normal operating mode. If during the startup phase the sensor on the flue gas outlet shows a rise in temperature (sign that the combustion process is underway), the stove is considered to be lit and goes into the normal operating mode. If during the startup phase the sensor on the flue gas outlet does NOT show a rise in temperature (sign that the combustion process is not underway), the stove should be considered off; a new ignition cycle will begin automatically and the three preceding phases will be repeated in succession.

6.9 Multicomfort

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.

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 under the paragraph “Multifuoco system”). You can position the remote control in the room to where the hot air has been ducted and set the required temperature from this room. To carry out the necessary settings see the Multicomfort menu.

6.11 How the ‘Multifuoco’ system works

The pellet stove with ‘Multifuoco’ system is fitted with a fan for the diffusion of hot air. 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. The workings 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, a number of ‘Multifuoco’ settings have been pre-programmed: M1, M2, M3. Once the ‘Multifuoco’ setting has been selected the user can choose a higher or lower amount of heat by selecting one of the four power settings on the stove. There is a greater volume of air transferred by the fan passing from setting M1 to M4. Similarly, there is a greater quantity of hot air produced by the stove passing from setting P1 to P4.

It is at the user’s discretion, based upon experience and familiarity in using the product, which of the ‘Multifuoco’ settings and which power level to choose. These choices will be based on the stove location, the room temperature at the time of lighting the stove and of course the required room temperature.

For each of the solutions described in the Multifuoco System section there is a specific MULTIFUOCO fan setting: M1, M2, M3, M4, to adapt fan speed to the chosen ducting method. If opting for Solution 1, it is best to use the control panel to select the corresponding setting “M1”. This setting will automatically adjust the fan speeds to the chosen solution and in proportion to the FOUR stove power settings. If opting for Solution 2, a higher fan speed will be required, in which case it would be best to select setting “M2” on the control panel. Finally, if opting for Solution 3 and Solution 4, an even higher fan speed will be required, in which case it would be best to select setting “M3” or “M4”. To select the required Multifuoco setting, refer to the paragraph “NORMAL OPERATION”.

.16 Safety devices

during operation some parts of the stove (door, handle, ceramic parts) can reach high temperatures.

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.

The 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.

SMOKE CHAMBER PRESSURE

Sensor Description Display

Pressure switch “ALF 1”

Connected to the flue gas outlet, its function is to control the vacuum inside the outlet duct so that the stove can be used in all safety.

WHEN ACTIVATED

If correct operating conditions in the flue gas outlet change (incorrect installation, blockages or obstructions in the flue, poor maintenance, unfavourable weather conditions such as persistent wind, etc.) the pressure switch cuts off the power supply to the fuel-loading auger, thereby stopping the supply of pellets to the grate and starting the stove shutdown process.

- The readout ‘ALF 1’ appears in the STOVE STATUS mode.

- The readout "SMOKE SAFETY " appears on the display.

- After approx. 60 seconds the alarm sounds (if activated).

WHAT TO DO

- Shut down the stove by holding the ON/OFF key (1) down for several seconds.

- The alarm stops.

- Wait until you are sure that combustion of any pellets remaining in the grate has stopped.

- Wait until the stove has cooled down, then check for and remove whatever has caused the safety device to be triggered. Finally, after having cleaned the grate restart the stove by pressing the ON/OFF key (1).

Pressure switch “ALF 2”

Its function is to check correct operation of the pressure switch so that the stove can be used in all safety.

WHEN ACTIVATED

It activates during the “START” stage of the stove (see “STARTING THE STOVE” table). If an anomaly is detected in the pressure switch, the readout "ALF 2" appears in the STOVE STATUS mode. The readout "SMOKE SAFETY" appears on the display. After approx. 60 seconds the alarm sounds (if activated).

WHAT TO DO

- Shut down the stove by holding the ON/OFF key (1) down for several seconds.

6.16 Disposal of ashes

• The ashes should be placed in a metal container with a sealed cover. The sealed container should be placed on a non-combustible surface at a safe distance from combustible materials until the cinders have been completely extinguished.

• 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.

• Ash from natural (non-treated) wood burned in stoves or open fireplaces 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 10m2 annually.

7.1 Cleaning the grate and the grate support - Fig. 64

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.

The frequency of cleaning depends on how much the stove is used and the quality of the fuel

Before lighting the stove, check that the grate is correctly inserted and pushed towards the left. Refit the grate baffle plate.

7.2 Cleaning the ash tray

Every two days, check the ash tray to see if it needs emptying. For the disposal of ashes see section 6.16.

7.3 Cleaning the firebox - Fig. 64 / 66

Once a week clean the firebox as follows:

• Remove the grate and the ash pan (fig. 64).

• Turn the eccentric clamps clockwise 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 counter-clockwise.

• Replace the grate, pushing it to the left.

This type of cleaning requires a vacuum cleaner suitable for holding ash.

.8 Cleaning the glass (DAILY)

The glass should be cleaned when cold using ammonia-based degreasing agents and not corrosive substances such as solvents. If the appliance is very slow to heat up in the ignition phase due to fuel that isn’t completely dry, this is likely to cause a build-up of tar on the glass. This will eventually burn off when the secondary air supply is opened (if the appliance is equipped accordingly) or when the appliance is operating at full capacity. If 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.

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

.9 Replacing the window

The stove is fitted with a 4mm thick glass panel, resistant to thermal shock up to 750ºC; 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.

If other problems occur, consult your nearest retailer.

7.10 Replacing the remote control battery

Disconnect the appliance from the electricity supply by pulling out the plug. 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. Replace the back cover on the remote control. Reconnect the appliance to the electricity supply. 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 and it is necessary to wait a few moments until the initial display returns before using the remote control.

If the above sequence has not been followed correctly as described: open the remote control flap; press the SET and OPT buttons simultaneously and program the transmission unit. See “Changing the transmission unit” paragraph.

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.

7.11 Cleaning the fans

Any 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.

7.12 When 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, the firebox and the ash drawer;

• clean the flue thoroughly: contact a professional chimneysweep for this purpose;

• clean 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.

7.13 Extraordinary 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.
