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, replace 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;

- 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).

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/replace 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;

- 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  replace is installed of another appliance or an extractor device.

a Do not use two stoves, a replace 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 replace 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 replace 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, referring to the weight of the product given in the paragraph “TECHNICAL DATA”. If the oor does not have a suitable load-bearing capacity, adequate countermeasures must be taken.

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.

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 1.5mm), 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 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 4,5 m+1 m=5,5 m.

•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+1 m+1 m=6,5 m.

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. 19).

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. 20).

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. 21-22).

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/m3.

•If the connector has to pass through non-ammable partitions or walls, create an insulating barrier equal to or greater than 5cm

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. 23);

- 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”.

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

a When a ue 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 “CONNECTING TO A CONVENTIONAL CHIMNEY”.

•It is also recommended that all elements made of combustible or inammable material, such as beams, wooden furniture, curtaining, ammable liquids, etc. be kept outside the heat radiation range of the stove and at a distance of at least 80 cm from the heating block.

•For other information, see the paragraph “MINIMUM SAFETY DISTANCES” and “CONNECTING TO A CONVENTIONAL CHIMNEY”.

•The ue pipe, chimney stack, chimney and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least

twice during the seasonal period from the lighting of the stove and during its use. When the stove has not been used for some time it is advisable to carry out the checks mentioned above. For further information, consult a chimneysweep.

•Only use recommended fuels (See section “FUEL”).

English

The wood pellet is obtained by pressing wood sawdust left over from the working of natural dried wood. The typical small, cylindrical form is obtained by passing the material through a die. Thanks to lignin, a natural element which is released during the pressing of the raw material, the pellets acquire a good consistency and compactness without requiring treatment with additives or caking agents. There are various types of pellet on the market with qualities and characteristics that vary depending on the processes they have undergone and the type of wood used in their production.

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 to electrical parts.

Cladding

•Having completed assembly of the stove and installed any external room thermostat, proceed with assembly of the stove cladding, referring to the ceramic cladding instruction booklet provided with the stove.

5.0 INSTALLATION

•Thanks to Piazzetta technology and R&D, this pellet stove offers the advantages of the “Multifuoco system”, a system EXCLUSIVE 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. 26). This exclusive oor-standing heat distribution system offers notable advantages: even spread of temperatures (Fig. 25). The hot air produced is propelled by a fan and distributed via the grille in the bottom front of the stove.

•This grille is tted with an adjustable ap.

•To direct the outow of hot air as required, adjust the angle of the ap

by pressing on the part of it that projects (Fig. 27).

Instructions for ducting the hot air

•The fan kit, which propels hot air into the room, can be tted with a

Y-element which effectively allows the hot air ow to be doubled up, directing it via a hose also to the rear of the stove, from where it can then be ducted to adjoining rooms.

•Some examples of possible installation are given below as well as examples of how to duct the hot air in order to heat other rooms.

Such examples are given purely for demonstration purposes;

best efciency can be obtained using Ø 75 mm coated ducting in accordance with instructions given in the sub-paragraph “Wall and oor ducting” and with a maximum total hose length of 16 metres. This length consists of the sum of the single lengths of hoses for each fan.

a It is of fundamental importance that when ducting heat from

the rear of the stove, the outlet vents near the stove or the Y-element must not be closed in order to avoid overheating. In cases where only one rear outlet from the fan is envisaged, the outlet vent must always be kept open.

•The examples show the ducting. Each diagram gives just one example of the many possible solutions.

Solution 1 - Fig. 28 - 29:

The stove is installed in the room which is to be heated, with the hot air directed to the front only, as when the stove arrives from the factory (Fig. 28). Alternatively the air can ow to the rear by connecting a 7.5 cm-diameter hose to the fan outlet (Fig. 29). In this set-up the stove heats the room where it is installed by radiation only, and heats the adjoining room through the ductwork to the rear.

a For the example shown in g. 29 it is necessary to use an

outlet vent 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, with the installation of a Y-element, also to the rear thereby allowing the heating of a second room. A Ø 7.5 cm hose with a maximum length of 16 metres is connected to the fan outlet (Fig. 30).

a For the example shown in g. 30 with single duct, the

outlet vent must be partially open but never closed to avoid overheating.

Solution 3 - Fig. 31:

Extension of the previous solution, with the stove installed in the room to be heated and the air ow ducted to the front and the rear, but using a second Y-element to double the ducting at the rear as shown. Maximum total length of the hoses 16 metres. (Fig. 31).

a For the example shown in g. 31, for efcient ducting and to

avoid overheating, the outlet vent closest to the Y-element must be partially open but never closed to avoid overheating.

Wall and oor ducting - Fig. 32 / 35

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;

- the maximum total length of the hose connected to the fan must not exceed 16 metres.

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. 36

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.

6.2 REMOTE CONTROL

•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.

•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. Do leave leftover pellets on top of the stove – they could catch re!

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

•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.

IDuring 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. 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.

6.5 TROUBLESHOOTING

A list of situations that could occur and instructions on what to do is given below.

FAILED IGNITION

Description Display

The stove is in the startup phase, the readout “NO LIT” appears on the display and the warning buzzer sounds (if set). The stove does not light because the ue gas outlet sensor does not detect an increase in temperature (sign that the combustion process has not been triggered) or because there is no pellet feed. If the stove is new or has gone out having fully burned the pellets in the grate, even though the hopper is full, it may be that in the ignition phase the pellets are not being fed into the rebox due to the auger not yet having been fully loaded.

NO LIT

Shut the stove down by pressing the ON/OFF key down for a few seconds. The warning buzzer stops. The readout CLEANING BRAZIER appears on the display and when the stove has cooled the readout

OFF appears. Empty the grate completely and set a new ignition cycle (see the table LOAD AUGER in the section

PARAMETERS MENU). Repeat the ignition process as described above.

CLEANING BRAZIER

1 2:0022

a Do not empty the contents of the grate into the hopper because there may be unburnt pellets present. a If the stove occasionally fails to ignite it could be caused by:

- pellet composition or size not in compliance with the specications given in this booklet (see the “FUEL” section);

- insufcient mains voltage.

In the above cases any call-out of the service centre is not covered by the warranty, since the problem is not due to a defect in the product.

DT2012310-00

SWITCHING OFF DURING THE START PHASE

Description Display

The stove is in the START PHASE I and is turned off by the user pressing the ON/OFF key. The readout “EMPTY BRAZIER” appears on the display.

INTERRUPTION OF POWER SUPPLY

Description Display

If there is a blackout while the stove is in operation, there are two possibilities of procedure according to stove set-up:

- blackout without timer thermostat settings;

- blackout with timer thermostat settings.

Blackout without timer thermostat settings.

When the electricity supply is restored, the appliance restarts automatically.

•The grate cleaning phase activates.

•The fan operates at full speed to allow the stove to cool.

•The automatic stove restart cycle starts (the steps detailed in the ‘STARTUP’ phase are repeated

automatically).

•Once the ignition cycle has been completed the stove operates normally at power level 2 with Multifuoco on 2.

Blackout with timer thermostat settings.

There are 3 possible situations.

- Blackout straddling the time set for ignition: the stove does not restart.

- Blackout straddling the time set for shutdown: the stove restarts when the electricity supply is restored.

- Blackout within the programmed operating time band: the stove restarts when the electricity supply is restored.

Restarting is carried out with the same procedure as listed in “Blackout without timer thermostat settings”.

6.11 MULTICOMFORT

The pellet stove is tted 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 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 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.

MULTICOMFORT

This function is used to choose the sensor for reading the room temperature: from the stove or from the remote control. To make the most of the Multifuoco fan functions read the sections MULTIFUOCO SYSTEM and MULTICOMFORT OPERATION.

MULT I COMFORT

SELECT RRC

SELECT STOVE

a If the MULTICOMFORT function is set on the remote control and for some reason there is no communication between the remote

control and the stove, after approx. 2 minutes the reference sensor will automatically change to become the sensor installed on the stove. It should be borne in mind that if the stove status was OK (power 1) as a result of the 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.

6.12 ENERGY SAVING

When the ENERGY SAVING mode is enabled, automatic startup/ignition and shutdown of the stove is activated at temperature values set by the user through the STOP and START functions. Values from 1 to 3 and the OFF option may be set for each STOP and START function. The value set from 1 to 3, added to (STOP) or taken away from (START) the programmed room temperature, denes a new temperature at which the STOP and START function will activate.

The operating principle is as follows: when the room temperature measured by the room sensor, the remote control or the external thermostat reaches the temperature value programmed

H07026300 / DT2000786 – 00

English

by the user, the stove automatically goes to power level 1 (readout “OK” on the display).

If the room temperature continues to rise with operation at power level 1 up to the value set on the STOP function (e.g. + 2°C compared to the programmed temperature), the stove shuts down and goes into the stand-by mode. When the room temperature measured by the room sensor, the remote control or the external thermostat drops to the temperature value set by the user on the START function (e.g. - 3°C compared to the programmed temperature), the stoves starts a new ignition phase and goes back to the power level previously set by the user.

a The stove only restarts when the temperatures measured on the actual stove allow its use in all safety.

If the STOP and OFF functions are enabled, upon reaching the programmed room temperature, the stove will operate in the conventional way by going to power level 1 without shutting down. Likewise with the START and OFF enabled the stove does not start the startup/ignition phase after automatic shutdown and will remain off.

DT2011839-00

6.17 ‘MULTIFUOCO’ SYSTEM OPERATION

The pellet stove with ‘Multifuoco System’ is tted with one/two fans for the circulation of hot air according to the model. This system allows several solutions for the distribution of ducted hot air, so that the user has freedom of choice as regards the number of adjoining rooms which can be heated. Operation of the ‘Multifuoco System’ will be explained in general and conceptual terms below. In order to adjust the fan to suit the chosen ducting solution, three ‘Multifuoco System’ speed settings have been pre-programmed, which appear as 01, 02, 03 in the bottom line of the display and as small rectangles from 1 to 3 in the top line. There is a greater volume of air transferred by the fan passing from speed setting 01 to 03. Once the ‘Multifuoco System’ speed has been set, the user can choose a higher or lower amount of heat by selecting one of the four power settings on the stove: P1, …, P4. Similarly, there is a greater quantity of hot air produced by the stove passing from power setting P1 to P4.

It is at the user’s discretion, based upon experience and familiarity in using the product, which of the ‘Multifuoco’ speed settings and which power level to choose. These choices will be based on the length of the ducting and the required room temperature (as an indication, the longer the ducting the higher the Multifuoco System speed setting).

For each of the solutions described in the INSTALLATION section under “MULTIFUOCO SYSTEM”, there is a specic Multifuoco fan setting recommended. If opting for SOLUTION 1, it is best to use the control panel to select the speed setting “01”. If opting for SOLUTION 2, a higher fan speed will be required, in which case it would be best to select the speed setting “02” on the control panel. Finally, if opting for SOLUTION 3, an even higher fan speed will be required, in which case it would be best to select the speed setting “03” on the control panel. To select the required Multifuoco setting, refer to the paragraph “STARTUP AND NORMAL OPERATION”.

6.18 SAFETY DEVICES

a 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 ue, 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 tted with several safety devices to guarantee safe operation.

a The safety devices are tted 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.

A list of warnings that could appear and instructions on what to do is given below.

SMOKE CHAMBER PRESSURE

Description Display

A pressure switch is connected to the ue gas outlet; its function is to control the vacuum inside the outlet duct so that the stove can be used in all safety.

The readout “SAFETY SMOKE” appears on the display. The causes could be that the correct operating conditions inside the ue gas outlet duct have been altered (poor installation, presence of obstructions or obstacles in the outlet duct, careless maintenance, unfavourable weather conditions such as persistent wind, etc.) or that a fault in the pressure switch has been detected. The warning buzzer activates after approx. 60 seconds (if set).

capacity, shown as MAX, otherwise the electrical parts of the stove could be damaged.

DT2010049-04

6.21 DISPOSAL OF ASHES

Ash from natural (non-treated) wood burned in stoves or open replaces 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.

a 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.

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.

STOVE ROOM TEMPERATURE SENSOR

Description Display

A sensor is connected to the rear of the stove; it constantly monitors the temperature in the immediate vicinity of the stove to ensure that it can be operated in all safety.

The symbol “00” appears on the display in place of the room temperature. It means that the sensor has been momentarily disconnected or accidentally dislodged. The problem does not require the immediate shutdown of the stove, which will continue to operate normally at the set power level.

7.7 CLEANING THE ENAMELLED METAL PARTS

DT2010062-05

7.8 CLEANING THE GLASS (DAILY)

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.

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

7.9 REPLACING THE WINDOW

The stove is tted with a 4 mm thick glass panel, resistant to thermal shock up to 750°C; the glass can only be broken by heavy impact or misuse. Do not slam the door or hit the window. In case of breakage replace only with a Gruppo Piazzetta spare part. To replace, proceed as follows:

- wear protective gloves;

- remove the door and lie it at;

- loosen the screws visible on the inside of the door;

- remove the frame and glass carefully;

- if the breglass 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 BATTERIES

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.

a Rechargeable batteries are unsuitable for the remote control as

they do not guarantee sufcient voltage for correct operation.

Replace the back cover on the remote control. The writing shown to the side appears on the display of the remote control. A feedback procedure between the remote control and the receiver starts automatically. After a few seconds the initial display returns. In other words, stove status prior to changing the batteries will be displayed. E.g.: if the stove was shut down, the display will appear as shown to the side. The new batteries must be of the same type as above; failure to comply with these instructions could cause a risk of explosion.

The old batteries must be disposed of properly in compliance with the applicable laws in force.

7.11 CLEANING THE FANS

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 room) positioned at the bottom and 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 at least once a year.

a Since such a procedure involves dismantling certain parts of

the stove, have the cleaning carried out only by a Piazzetta Service Centre or other qualied persons.

To access the room fan/s, remove the side ceramic panel/s (see instructions in CLADDING booklet). Remove the cover plate [A] screwed onto the external housing by loosening the screws. (Fig. 67)

7.13 EXTRAORDINARY MAINTENANCE

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 on request, 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.

The following maintenance should be carried out ONCE A YEAR and is necessary to ensure efcient and safe stove operation:

- clean the rebox thoroughly;

- clean and inspect the ue;

- check the condition of seals and gaskets;

- clean mechanical and moving parts (motors and fans);

- check electrical and electronic components.

Problem Cause Solution

a Some of the problems indicated below may be resolved by following the instructions. All work must be carried out when the appliance

is cold and disconnected from the electricity supply (pull out the plug).

a Authorised qualied persons must be contacted, in accordance with current regulations, whenever it is necessary to work on parts

inside the cladding or the rebox in order to resolve the problem. It is therefore recommended that only “Gruppo Piazzetta S.p.A.” authorised Service Centres be contacted. Whenever authorised Service Centre personnel carry out work, they must show an identity card issued by Gruppo Piazzetta S.p.A. on which the following are printed: name of the Service Centre, stamp and signature of the company and the period of validity of the actual document.

a Unauthorised tampering with the appliance or the use of other than original spare parts not only creates situations of risk for operator

safety, but invalidates the warranty and relieves the manufacturer from all liability.
