PRODUCT PERFORMANCE CHECKS
All our products undergo ITT TESTS carried out by a notified third-party laboratory (system 3) and in accordance with Regulation (EU) number 305/2011 “Construction products”, according to standard EN 14785:2006 for household appliances and “Machinery Directive” EN 303-5 for boilers. In the case of tests for any market surveillance or inspections by third parties, please consider the following warnings:

• To reach the declared performance levels, the product must perform an operating cycle of at least 15-20 hours beforehand.
• Set the average draught of the combustion fumes as specified in the “technical product features” table The type of pellets used must comply with the current EN ISO 17225-2 class A1 regulation. Fir pellets are usually used for certification.
• The amount of thermal energy can vary according to the length and calorific value of the fuel. This may require some adjustments (accessed from the user menu) to comply with the hourly consumption specified in the “technical product features” table. Using class A1 pellets guarantees a calorific value that is likely to be close to that used in the product certification; the size of the pellet grains can significantly affect hourly fuel loading and consequently performance; it is therefore suggested to use pellets with a 6 mm diameter and an average length of around 24 mm (avoid pellets that are too long or excessively crushed).
• With wood-burning appliances, the fuel must comply with the current EN ISO 17225-5 class A1 regulation. Check the correct moisture of the fuel, as it must be within the range of 12 – 20% (it is best if the moisture is close to 12%, as is normally used in certification). As the fuel moisture increases, different combustion air settings are required, which are implemented from the combustion air register, thereby modifying the mixture of primary and secondary air
• It is important to check the operation of devices that can affect performance (for example air fans or electric safety devices) in case of damage due to handling.
• Nominal performance has been obtained by setting the maximum flame power and room ventilation in manual mode. Performance at reduced power was achieved at minimum flame and ventilation power (P1 and V1) in manual mode. The other conditions correspond to intermediate ventilation and power.
• If a “verification” mode is provided in the menu, set this function during the readings to ensure that no temperature modulation occurs due to an incorrect setting of the operating parameters.
• Lastly, strictly comply with the sampling points specified in the regulations in terms of emissions as well as temperature

We furthermore point out that these operating conditions increase the risk of premature wear of the product, especially those parts exposed to the direct heat of the fire (e.g. combustion chamber), the original condition of which can undergo modifications and deterioration which, among other things, could generate noise during operation of the unit due to mechanical expansion.

The manufacturer will not be held liable if the above information is ignored.

2-INSTALLATION
The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the regulations in force in the country of installation.

PELLETS
The pellet is obtained from natural dried wood sawdust (without paint). The compactness of the material is guaranteed by the lignin contained in the wood itself, without glue or binders. The market offers different types of pellets with characteristics that vary according to the wood mixtures. The most common diameter on the market is 6 mm (although an 8 mm diameter is also available) with a length, on average, between 3 and 40 mm. A good quality pellet has a density of between 600 and 750 or more kg/cubic meters and a moisture content that accounts for 5 to 8% of its weight. Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner combustion than that of fossil fuels. While good- quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), that of pellets is around 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg bags, therefore, storing them is very convenient. Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.

The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber need to be cleaned. The main quality certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to ISO 17225-2. These certifications include, for example, ENPlus, DINplus, Ö-Norm M7135, and specifically assure that the following characteristics are complied with:

•  calorific value: 4.6 – 5.3 kWh/kg.
• Water content: ≤ 10% of the weight.
• Percentage of ash: max 1.2% of the weight (A1 less than 0.7%).
• Diameter: 6±1/8±1 mm.
• Length: 3-40 mm.
• Content: 100% untreated wood without the addition of binding agents.

The company recommends using certified fuel for its products (ENPlus A1, DINplus, Ö-Norm M7135). The use of pellets that do not comply with the characteristics specified previously may compromise the operation of your product and therefore invalidate the warranty and product liability.

FOREWORD
The heating system (generator + combustion air supply + combustion product expulsion system + any hydraulic/aeraulic system) must be installed in compliance with the laws and regulations in force1 and carried out by a qualified technician, who must issue a declaration of conformity of the system to the system manager and shall undertake full responsibility for final installation and consequent good operation of the product. The manufacturer declines all responsibility in the event of installations that do not comply with the laws and regulations in force and inappropriate use of the appliance.
In particular one must ensure that:

• the environment is suitable for installing the appliance (floor load-bearing capacity, presence or possibility of creating an adequate electrical/hydraulic/aeraulic system when required, volume compatible with the appliance characteristics, etc.);
• the appliance is connected to a smoke expulsion system correctly sized according to EN 13384-1, which is resistant to soot fire and complies with the distances prescribed by the combustible materials indicated on the plate data;
• there is a suitable combustion air flow to the appliance;
• other combustion appliances or extraction devices installed do not cause a negative pressure of more than 4 Pa in the room where the product is installed compared to the outside (only sealed appliances are allowed a maximum of 15 Pa of negative pressure in the room).

The national reference standard for the installation of domestic appliances is UNI 10683 (IT) – DTU NF 24.1 (FR) – DIN 18896 (DE) – NBN B 61-002 (BE) – Real Decreto 1027/2007 (ES) In particular, it is recommended to strictly observe the safety distances from combustible materials to avoid serious harm to people and to the integrity of the home. Installation of the appliance must ensure easy access to service the appliance itself, the smoke channels, and the flue. Always maintain adequate distance and protection in order to prevent the product from coming into contact with water. It is forbidden to install the stove in rooms with a fire hazard. With the exception of sealed installations, it is also forbidden for liquid fuel appliances with continuous or intermittent operation that draw the combustion air from the room they are installed in or B-type gas heating appliances, with or without the production of domestic hot water, to coexist in the same room or in interconnecting rooms.

Sealed installation means that the product is certified as sealed and its installation (ducting of the combustion air and connection to the chimney) is airtight with respect to the installation environment.A sealed installation does not consume the room’s oxygen but draws all the air from the outer environment (if suitably ducted) and makes it possible to install the product, therefore, it can be installed in all houses that require a high degree of insulation such as “passive” or “high energy efficiency” houses. Thanks to this technology there is no risk of smoke emissions in the room, hence no air inlets and relevant ventilation grilles are required in the installation premises. Consequently, there will be no more draughts of cold air in the room, which would otherwise make it less comfortable and reduce the overall efficiency of the system. The sealed stove may even be installed in a sealed installation that is compatible with the presence of forced ventilation or in premises that might have negative pressure with respect to the outside.

MINIMUM DISTANCES
Observe the distances from flammable objects (sofas, furniture, wood paneling, etc…..) as specified in the following diagram. If objects considered to be particularly sensitive to heat are present, such as furniture, curtains, or sofas, as a precaution, increase the stove clearances substantially to avoid possible deterioration due to the effect of heat. If the floor is made of combustible material, use protection made of non-combustible material (steel, glass…) that also protects the front from any falling combusted material during cleaning operations. Always fit a floor guard if the floor is made of flammable material. Install the stove also detached from any non-combustible walls/surfaces, observing a minimum clearance of 40/120 mm (back) and 100/200 mm (side) to allow effective aeration of the appliance and a good distribution of heat in the room.

In any case, ensure adequate distance to facilitate access during cleaning and extraordinary maintenance. If this is not possible, it must still be possible to distance the product from adjacent walls/elements.
This operation must be performed by a technician qualified to disconnect the combustion product expulsion ducts and their subsequent restoration. For generators connected to the hydraulic system, a connection must be provided between the system itself and the product so that, during extraordinary maintenance, carried out by a qualified technician, it is possible to move the generator by at least 50 cm from adjacent walls without emptying the system (e.g. by using a double shut-off gate or suitable flexible connection).

Air inlet
It is mandatory to provide an adequate external air inlet that supplies the combustion air required for the product to work properly. The flow of air between the outside and the installation room can take place with a free air inlet or by channeling the air directly to the outside.

The free-air inlet must

• be made at floor level
• always be protected with an outer grille and in such a way that it cannot be obstructed by any object
• have a minimum total free area of 80 cm2 (net of the grille)

The presence of other suction devices (e.g.: vmc, electric fan for stale air extraction, kitchen hood, other stoves, etc.), in the same room could cause negative pressure in the room. In this case, with the exception of sealed installations, one must verify that, with all the equipment on, no more than 4 Pa of negative pressure is created inside the installation room with respect to the outside. If necessary, increase the air inlet section. It is possible to duct the air required for combustion to the outside by connecting the external air inlet directly with the combustion air inlet which is usually found on the back of the appliance. The duct must comply with the following dimensions (each 90° bend is equivalent to one linear meter): 3 In the event the combustion air is ducted on unsealed products, still verify that no more than 4 Pa of negative pressure is created inside the installation room with respect to the outside, otherwise provide for an additional air intake in the room.

Preparing the smoke expulsion system

The combustion product expulsion system is a particularly important element for the proper operation of the appliance and must be correctly sized according to EN 13384-1. Its creation/adaptation/verification must always be carried out by a legally qualified operator and must comply with the regulations in force in the country where the appliance is installed. The Manufacturer declines all liability for malfunctions caused by a badly sized and non-compliant smoke expulsion system.

Smoke duct (smoke fitting)
The smoke duct is the pipe that connects the appliance to the flue. This smoke fitting must comply in particular with the following requirements:

• comply with product standard EN 1856-2;
• its cross-section must be of constant diameter and no less than that of the appliance outlet, from the firebox outlet up to the connection in the flue;
• the horizontal section must be as short as possible and extend no more than 4 meters;
• the horizontal sections must have a minimum upward slope of 3%;
• changes of direction must have an angle no greater than 90° and be easy to inspect
• the number of changes of direction, including that for entry into the flue, and exclusion of the T in the event of a side or rear outlet, must not exceed 3;
• it must be insulated if it passes outside the installation room
• it must not in any case cross rooms in which it is forbidden to install combustion appliances.
• the use of flexible metal and fiber cement or aluminum hoses is forbidden;

In any case, smoke ducts must be sealed against combustion products and any condensation. For this reason, it is recommended to use pipes with silicone gaskets or similar sealing devices that withstand the operating temperatures of the appliance (e.g. T200 P1) and that by removing the gaskets, are still T400 N1 G certified.

Flue (chimney or piped duct)
When creating the flue, in particular, comply with the following requirements:

• comply with the applicable product standard (EN 1856, EN 1857 EN 1457, EN 1806, EN 13063..);
• be made with suitable materials to ensure resistance to normal mechanical, chemical, and thermal stresses and have adequate thermal insulation in order to limit the formation of condensate;
• have a predominantly vertical configuration and be free of choke points along its entire length;
• be correctly spaced by air gaps and isolated from combustible materials;
• the flue inside the house must still be insulated and can be inserted in an air shaft provided it complies with the regulations for piping;
• the smoke duct must be connected to the flue by means of a Tee fitting with an inspectable collection chamber for the collection of soot and any condensate.
• where the sizing provides for wet operation, a suitable condensate collection, and siphon discharge system must be set up.

We recommend checking the data plates of the flue for the safety distances that must be observed in the presence of combustible materials and, if necessary, the type of insulating material to be used. It is forbidden to connect the stove to a collective or shared flue (*) with other combustion appliances or with hood outlets. It is forbidden to use the direct drain on the wall or towards indoor spaces and any other form of drain not provided for by the regulation in force in the country of installation.

Chimneypot
The chimneypot, meaning the end part of the flue, must meet the following characteristics:

• the smoke outlet section must be at least double the internal section of the chimney;
• prevent the penetration of rain or snow;
• ensure the outlet of smoke even in the event of wind (windproof chimneypot);
• the height of outflow must be beyond the reflux area (*) (refer to national regulations to identify the reflux area);
• always be built at a distance from antennas or dishes, and never be used as a support.

(*) unless there are specific national derogations (clearly specified in the corresponding instruction manual in English) which under appropriate conditions allow it; in this case, strictly follow the product/installation requirements of the relative regulations/technical specifications/legislation in force in that country.

EXAMPLES OF INSTALLATION4 (DIAMETERS AND LENGTHS TO BE SIZED)

1. Flue installation with a hole for the passage of the pipe increased by:

   • minimum 100mm around the pipe if next to non-flammable parts such as cement, brick, etc.; or

   • minimum 300mm around the pipe (or as required by plate data) if next to flammable parts such as wood etc.

   • In both cases, install suitable insulation between the flue and the ceiling.
     Always check and comply with the plate data of the flue, specifically the minimum safety distances from combustible materials.

   • The previous rules also apply to holes made in walls.

2. Old flue, pipe with the inclusion of an external access door for chimney cleaning.

3. External flue made of insulated stainless-steel pipes,i.e. with double walls: all securely mounted on the wall. With windproof chimneypot.

Handle the product with suitable means paying attention to the applicable safety regulations in force. Do not turn the packaging over and handle the majolica parts with care. The stoves are delivered in a single package with steel sides packaged together with the structure and placed at the side. Open the package, remove the cardboard, polystyrene, and any straps, and position the stove in the preset place making sure that it complies with the requirements. The stove body or unit must always be kept in a vertical position when handled and handled using trolleys only. Pay particular attention to the door and its glass, protecting them from mechanical knocks that would compromise their integrity. If possible, unwrap the stove near the chosen area of installation. The packaging materials are neither toxic nor harmful.

Remove the stoves from the pallet by removing the two screws “u” and the plate “s” from the stove foot. There are four “s” brackets. Position the stove and connect it to the flue. Use the 4 adjustable feet (J) to get the stove correctly leveled so that the smoke outlet is lined up with the connecting pipe. If the stove needs to be connected to an outlet pipe that goes through the rear wall (to connect to the flue), take the utmost care to make sure that the joint is not forced. If the stove smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

If the stove smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

On delivery, the stove has no metal cladding and with the top fitted, as shown in the image below. Take the box with the metal sides (figure below) and prepare them for installation. The sides are fitted with screws for fixing the structure.
Attention! Carefully handle the metal sides as the paint may be damaged.

To assemble the sides of the stove it is necessary to remove the top from the structure. Lift the pellet cover “G” by simply grasping it by the handle “f” and pulling it towards you. Remove the two screws “c” from under the cover.

REMOVING THE TOP
Now remove the entire top “F” and put it away safely.

FITTING THE SIDE PANELS
Take one of the metal sides “E” (they are reversible) and fit the silicone bumpers “s” on both tops of the panel. Insert the holes “u” on the bottom of the panel “E” on the hooks “z” in the structure of the stove. Then move panel “E” towards the structure and secure it with the two screws “x”. Place the M5 notched washer “z” between the screw “x” and the panel.

Fit the panel on the other side in the same way.

After completing the installation of the metal panels, refit the top “F” and secure it to the structure with the previously removed screws.

REMOVING THE REAR PANEL

In case of maintenance and/or interventions it is possible to remove panel “D”. Proceed as follows:

• Remove the screws “x” and the two M5 notched washers “z” from the top part
• lift panel “D” so that hooks “u” in the structure protrude from holes “v” on panel “D”
• place the panel in a safe place

REMOVING THE UPPER PANEL
Panel “K” is already fixed to the stove structure, it may be removed in the event of maintenance, servicing or cleaning. After removing any top and side ceramic panels, remove screws “x”, two on the right and two on the left, and remove the top front panel “K”.

ASSEMBLE THE TOP
Once the cladding has been installed, refit the top “F” (see chapter “Removing the top”).

DOOR OPENING
To open the firebox door “R”, insert the cold handle “Z” into the hole in the handle “P” and pull it towards you. To open the lower door “F”, pull the hook “L” with your hands towards yourself.

Caution! Only open the door when the stove is off and cold. Before opening the lower door “F” first open the firebox door “R”.

**CONNECTIONS TO ADDITIONAL DEVICES

**

Comfort Air ducting
Comfort Air stoves can channel the air into other rooms through the connection with the accessory pipes to the rear “S” shaped flange provided as per standard. The recommended maximum duct length is 8 meters per fan. It is advisable to set up ducts of similar length to distribute the hot air evenly in the various rooms. The outlet air pipe can reach very high temperatures, even around 150°C: therefore, it must be adequately insulated with suitable material, especially points that could come in contact with flammable surfaces or parts that are affected by heat (e.g. change in shades, wiring ducts, plasterboard, etc.). Moreover, persons and animals must be protected from accidental or intentional contact. In any case, comply with the regulations and laws in force in the region where the product is installed.
It is recommended to insulate the entire length of the pipe in order to reduce dispersion and increase heat output in the room.

If you do not wish to channel the air, the hot air may be let out through the rear “V” vent without connecting any pipe. The “V” vent and the “U” clamp used for fastening are found in a plastic bag inside the hopper of the stove.

Attention! It is mandatory to install the vents with “V” netting (1 or 2 depending on the type of appliance) on the rear “S” output for safety purposes and to prevent the rear wall from being hit directly by the hot air flow, generating halos, blackening or even dangerous heating in the case of flammable walls. When positioning the stove near a wall (see image below) direct the hot air “V” vent towards the free part. If this warning is not complied with, the manufacturer cannot be held liable for any damage to property and/or persons.

ELECTRICAL CONNECTION
First, connect the power cable to the back of the stove and then to a wall socket. It is recommended to disconnect the power cable when the stove is not used. The cable must never come into contact with the smoke exhaust pipe or any other part of the stove.

STOVE POWER SUPPLY
Connect the power cable to the back of the stove and then to a wall socket. The stove is then powered. There is a fuse box also in the switch block next to the power socket. Open this compartment by simply lifting the cover, using a screwdriver as a lever from inside the power outlet compartment. Inside there are two fuses (5×20 mm T delayed / 3.15 A 250 V), which may need to be replaced if the stove is not powered (e.g. the control panel display does not light up) – operation to be implemented by a qualified technician.

ATTENTION!
All cleaning and/or replacement of parts must be carried out with the power plug disconnected. Disconnect the product from the 230V power supply before performing any maintenance operations. If the cable is damaged, replace it.

LOADING THE PELLETS
Fuel is loaded from the upper part of the stove by lifting door “G”. Pour the pellets in slowly so that they are deposited at the bottom of the hopper.

If loading pellets when the stove is running, open the door of the tank using the cold handle that comes with the stove itself. When loading, do not let the pellet bag come into contact with hot surfaces. Never remove the protection grid inside the hopper. No type of fuel other than pellets is to be inserted into the hopper, in compliance with the above-mentioned specifications. Store the spare fuel at an adequate safe distance. Do not pour pellets directly onto the brazier but only into the hopper. When the appliance is running and when it is turned off, most of the stove surfaces are very hot (door, handle, glass, smoke outlet pipes, etc.). Therefore it is recommended to avoid coming into contact with these parts.
