1-WARNINGS AND WARRANTY CONDITIONS

SPARE PARTS

In the event of a malfunction, consult the retailer who will forward the call to the Technical Assistance Service.

Use only original spare parts. The retailer or service centre can provide all necessary information regarding spare parts. We do not recommend waiting for the parts to be worn before having them replaced. It is important to perform regular maintenance.

The company declines all liability if the product and any other accessory is used improperly or modied without authorisation. All parts must be replaced with original spare parts.

WARNINGS FOR THE CORRECT DISPOSAL OF THE PRODUCT.

The owner is the sole party responsible for demolishing and disposing of the product. This must be performed in compliance with laws related to safety and environmental protection in force in his/her country. At the end of its working life, the product must not be disposed of as urban waste. It must be taken to a special dierentiated waste collection centre set up by the local authorities or to a retailer that provides this service. Separating and recycling prevents potential negative eects on the environment and health (often caused by inappropriately disposing of product parts). It also allows materials to be recovered in order to obtain signicant savings in energy and resources.

2-INSTALLATION

The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the domestic regulations in force.

PELLETS

Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders. The market oers dierent types of pellets with characteristics that vary according to the wood mixtures used. The most common diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 5 and 30 mm. A good quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water 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. Good-quality wood has a caloric value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is 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.

15 Kg BAG OF FUEL

The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must be cleaned.

The main quality certications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to ISO 17225-2. These certications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular, guarantee the following characteristics:

• caloric value: 4.6 ÷ 5.3 kWh/kg.

• Moisture 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: ≤ 40 mm.

• Content: 100% untreated wood without the addition of binding substances (max 5% bark).

• Packaging: in sacks made from ecologically compatible or biologically decomposing material.

The company strongly recommends using certied fuel for its products (ENplus, DINplus, Ö-Norm M7135). Poor quality pellets or others that do not comply with the characteristics specied previously may compromise the operation of your product and can therefore render the guarantee and product liability invalid.

2-INSTALLATION

FOREWORD

The installation position must be chosen according to the room, to the smoke extraction system, to the chimney ue. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the ue or the chimney cap. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance. The installation must be carried out by a qualied technician, who must issue a declaration of conformity of the system to the purchaser and will assume full responsibility for nal installation and consequent good operation of the product. In particular one must ensure that:

• there is a suitable combustion air inlet and smoke outlet in compliance with the type of product installed

• other stoves or devices installed do not cause depression in the room where the product is installed (for sealed appliances only, a

maximum of 15 Pa of depression in the room is allowed)

• when the product is switched on there is no reux of smoke in the room

• fumes extraction takes place in total safety (sizing, smoke seal, distances from ammable materials..).

We especially recommend to check the data tags of the ue for the safety distances that must be observed in presence of combustible materials and the type of insulating material to be used. These indications must be followed strictly to prevent serious harm to people and the integrity of the home. The installation of the appliance must ensure easy access to clean the appliance itself, the smoke outlet pipes and the ue. It is forbidden to install the stove in rooms with a re hazard. Installation in studio ats, bedrooms and bathrooms is only allowed with sealed or closed appliances equipped with suitable combustion air ducting directly outside. Always maintain adequate distance and protection in order to prevent the product from coming into contact with water.

In the event there are several appliances installed, the external air inlet must be sized accordingly.

MINIMUM DISTANCES

It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow eective aeration of the appliance and a good distribution of heat in the room. Observe the distances from ammable or heat-sensitive objects (sofas, furniture, wood panelling, etc..) as specied. The front distance from inammable materials must be at least 80 cm. If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.

If the oor is made of wood, it is recommended to t a oor protection sheet in compliance with the Standards in force in the country of installation.

Non-ammable walls Flammable walls

TRAY/CAP/LAM

A = 5 cm B = 5 cm

If the oor is made of combustible material, it is recommended to use protection made of non-combustible material (steel, glass...) that also protects the front from falling combusted material during cleaning operations. The appliance must be installed on a oor with adequate load capacity. If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).

2-INSTALLATION

FOREWORD

This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856

- EN1457). The chapter provides indications for installing an ecient and correct smoke ue but is under no circumstances to substitute the regulations in force, which the qualied technician must be in possession of. Check with local authorities whether there are any restrictive regulations in force regarding the intake of air for combustion, the smoke extraction system, the ue or the chimney. The company declines all liability relating to the poor functioning of the boiler if this is due to the use of an insuciently sized ue in violation of regulations in force.

SMOKE FLUE

The ue or chimney is of great importance for the proper operation of a solid fuel-burning heating appliance with natural draught, as modern heating appliances have high eciency with cooler ue gasses and consequently less draught, it is therefore essential that the ue is built up to standard and always kept in perfect working order. A ue that serves a pellet/wood fuelled appliance must be at least category T400 (or greater if the appliance requires, and resistant to soot res. Smoke must be extracted through a single ue made of insulated steel (A) or an existing ue that complies with the intended use (B). A simple air shaft in cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch (AP) - FIG.1. It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same ue.

TECHNICAL CHARACTERISTICS

Have the eciency of the ue checked by an authorised technician. The ue must be sealed against ue gasses, in a vertical direction without narrowing, be made with materials impermeable to smoke, condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend replaces made of A/316 or refractory material with insulated round section double chamber). Be suitably insulated externally to avoid condensation and reduce smoke cooling. It should be separated from combustible or ammable materials with an air gap or insulating materials: check the distance specied by the manufacturer of the replace according to EN1443. The chimney opening must be in the same room as the appliance, or at most in the adjoining room, and have a soot and condensation collection chamber beneath the opening, and be accessible via a watertight metal hatch.

DIMENSIONING

The drop in pressure (draft) of a ue depends on its height. Check the drop in pressure with the values indicated in the technical characteristics. The minimum height of the chimney is 3.5 meters.

The interior cross-section of the ue can be circular (best variation), square or rectangular (the ratio between the interior sides must be ≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be minimum Ø100mm.

The cross-sections/lengths of the chimneys shown in the technical data tables are indications for correct installation. Any alternative congurations must be correctly dimensioned in accordance with the general method of calculation of UNI EN13384-1 or other proven eciency methods.

Below is a list of some ues available on the market:

Steel chimney AISI 316 with

double chamber insulated with ceramic bre or equivalent resistant up to

400°C.

Refractory chimney with double insulated chamber and external lightweight concrete cladding with cellular material such as clay.

Traditional square-section clay chimney with insulating empty inserts.

Avoid products with an internal rectangular section where the larger side is 1.5 times the smaller side (e.g. 20x40 or 15x30).

EXCELLENT GOOD POOR VERY POOR

2-INSTALLATION

MAINTENANCE

The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the ecient functioning of the heater and, if large build-ups accumulate, can catch re. The ue and chimney must be cleaned and checked by a qualied chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that the device is safe. Failure to clean the system jeopardises the safety.

CHIMNEY

The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7. The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/ue system, and arranged so

that smoke extraction is ensured even in strong wind. The chimney must prevent rain, snow or animals from entering the chimney. The height of outow into the atmosphere must be beyond the reux zone created by the

shape of the roof or any obstacles near

the outlet (see Figures 2-3-4-5-6).

2-INSTALLATION

EXTERNAL AIR INLET

It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The ow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b). Adjoining areas may not include sleeping areas, garages or general areas with a re hazard. During installation one must check the minimum clearances required for air intake from outside. Take into account the presence of doors and windows that could interfere with the proper ow of air to the stove (see diagram below). The air intake must have a minimum total net area of 80 cm2: the surface must be increased accordingly if within the room there are other active generators (for example: electric fan for stale air extraction, kitchen hood, other stoves, etc...), which could cause cause depression in the room. One must verify that, with all the equipment on, the pressure drop between the room and the outside does not exceed a value of 4 Pa. If necessary increase the intake section of the air inlet, which must be made at oor level and always protected with a birdproof outer protection grid and in such a way that it cannot be obstructed by any object.

It is possible to connect the air required for combustion directly to the outside air inlet, with a pipe of at least Ø50mm, with maximum length of 3linear metres; each pipe bend shall be considered equivalent to a linear metre. To attach the pipe see the back of the stove. For stoves installed in studio ats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside. In particular for sealed stoves the connection must be sealed in order not to compromise the overall sealed characteristic of the system.

1.5 m AWAY from smoke outlet

CONNECTION TO FLUE

The connection between the ue and the appliance must be via a smoke duct that conforms with EN 1856-2. The connecting section must extend no more than 4 m horizontally, with a maximum incline of 3% and containing a maximum of 3 90% bends (accessible for inspection - do not count the T joint at the appliance outlet). The diameter of the smoke duct must be equal to or greater than that of the appliance outlet (Ø 80 mm).

Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can withstand the high operating temperatures of the appliance (min. T200 class P1). The use of exible metal tubes in bre cement or aluminium is prohibited. For direction changes, we always recommend the use of a T joint with an inspection cap allowing easy access for cleaning the tubes. Always ensure that the inspection cap is replaced and hermetically sealed with the seal in tact after cleaning. It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to extract the products of combustion directly through the wall, whether into indoor spaces or outdoors. The smoke duct must be a minimum distance of 400 mm from ammable or heat-sensitive structures.

2-INSTALLATION

EXAMPLES OF CORRECT INSTALLATION

1. Installation of Ø150mm ue with hole for the passage of the tube increased by: minimum 100 mm around the tube if next to non ammable parts such as cement, brick, etc.; or minimum 300 mm around the tube (or as prescribed by

data tags) if next to ammable parts such as wood etc.

In both cases, install suitable insulation between the ue

and the ceiling. Always check and respect the data tags on the ue,

in particular the minimum safety distances from combustible materials. The previous rules also apply for holes made in walls.

2. Old ue, minimum pipe Ø100mm with the inclusion of an external access door for chimney cleaning.

3. External ue made of insulated stainless steel pipes,

i.e. with double walls minimum Ø100mm: all securely mounted on the wall. With wind-proof chimney. See g. 7 type A.

4. Ducting system using T joints that allow easy access for cleaning without having to remove the tubes

REMOVING THE FRONT PANEL

After removing the top, open the door "E", remove the four screws "v" at the bottom and remove the prole "Z". Remove the front panel "F" by removing the two screws "u" in the upper part of the stove and the two screws "v" (one per side) in the lower part. When you remove the front "F" pay attention not to damage its surface and that of the door "E".

7-LAM STOVE DISASSEMBLY

ASSEMBLY OF SIDE MESH PANEL

This is the only part that is delivered together with the structure, but not assembled. Take the side "G" and move it close to the structure and let the two lower hooks "K" and the two intermediate hooks "J" enter the structure. Then tighten the two upper screws "z" to securely fasten the panel to the structure. Repeat the same operation for both panels.

Attention!! If you have purchased an accessory kit (e.g. ventilation kit, web interface, etc.) it is recommended to install the accessories and then the side panels.

7-LAM STOVE DISASSEMBLY

ASSEMBLY OF THE STONE SIDE PANELS

The stone side panel kit consists of 4 identical panels and 2 panels rounded on one side. The two rounded panels are those that must be set in the lower part of the stove, with the round part facing downwards. Take the supplied plates and fasten them to the structure with 2 screws; in the lower part "F1", fasten the short part to the stove and in the upper part, fasten the longer part to the structure.

Attention!!! All the material is supplied and the holes of the plates are slotted to allow for easy adjustment.

7-LAM STOVE DISASSEMBLY

Take the rst panel "M" (with the curved part facing downwards) and insert it in the lower part of the structure using the bracket that is pre-assembled on the back of the panel (see detail "G1"). Then bring the panel close to the structure, rest the supplied bar ''Q'' on the top and insert the two pins ''x'' into the holes to fasten it to the stone panel (part of the pin will remain outside the bar ''Q'' in order to fasten the upper panel ''N''). Secure bar "Q" to the bracket "F1", previously fastened to the structure, with the screw "v".

7-LAM STOVE DISASSEMBLY

Take the panel "N" and place it in the pins "x". As for the panel below ("M") bring the panel close to the structure, rest the supplied bar

"Q" on the top and insert the two pins "x" into the holes to fasten it to the stone panel (part of the pin will remain outside the bar "Q" in

order to fasten the upper panel "O").

Complete the fastening operations by inserting the two pins "x" at the top.

8-LOADING THE PELLETS

LOADING THE PELLETS

The fuel is loaded at the top of the stove by lifting door “k” by its rubber handle. Pour the pellets in slowly so that it is deposited at the bottom of the hopper. The door has two opening modes, one to load the pellet and the other to clean the top inside part of the stove with a vacuum cleaner as needed. A grid “w” has been tted at the rst door opening step to prevent the pellet from escaping to the front of the stove. Inside the stove the word “MAX” can be seen on one side, indicating the maximum level of the pellet before it spills between the panels and the structure of the stove.

Never remove the protection grid inside the hopper. When loading, do not let the pellet bag come into contact with hot surfaces. No other type of fuel other than pellets is to be inserted into the hopper, in compliance with above-mentioned specications. Store the spare fuel at an adequate safe distance. Do not pour pellets directly onto the brazier but only into the hopper. Most of the stove surfaces are very hot (door, handle, glass, smoke outlet pipes, hopper door etc.), therefore it is recommended to avoid coming into contact with these parts without appropriate protective clothing.

8-LOADING THE PELLETS

The CAP stove top opening system is dierent from the TRAY stove. The rear pellet loading grid has the same system, all you need to do

is lift door “k” using the rubber handle, whereas the front grid “j” is lifted by about 15° to let the vacuum cleaner pipe in for cleaning any spilled pellet. Should this opening not be enough for cleaning, the two hooks “z” may be removed and door “j” may be pulled out.

8-LOADING THE PELLETS

LAM STOVE PELLET LOADING

Open the pellet loading door "A" by pulling the handle "s" on the right side of the stove, under the cover "A". At this point, lift the part of the rear cover "A", which is mobile at this point. Lift the protective grid "B" (by the rubber handle) for it to rest on the part of the front cover "B" of the stove. This is necessary to prevent the pellets from settling under cover "B".

9-FIRST START-UP

PRECAUTIONS BEFORE START-UP GENERAL PRECAUTIONS

Remove any objects that may burn from the brazier (manual, various adhesive labels or any polystyrene).

Check that the brazier is positioned correctly and rests properly on the base.

The rst start-up may not be successful as the feed screw is empty and does not always manage to load the required amount of pellets in time to light the ame.

CANCEL THE FAILED IGNITION ALARM BY PRESSING AND HOLDING THE ON/OFF KEY FOR A FEW SECONDS. REMOVE THE PELLET LEFT IN THE BRAZIER AND REPEAT THE START-UP. (SEE "SAFET Y DEVICES/ALARMS" PARAGRAPH)

If after repeated attempts, the ame fails to ignite, despite a regular ow of pellets in the brazier, which must rest snugly against the slots and be clean without any ash incrustations. If no anomaly is found during this inspection, there may be a problem with the

product components or installation may not be correct.

REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.

Do not touch the boiler during the rst lighting, as it is during this phase that the paint sets. If you touch the paint, you may expose the steel surface.

If necessary, touch up the paint with the spray can of the specic colour. (See "Pellet stove accessories")

It is good practice to ensure eective ventilation in the room during the initial start-up, as the boiler will emit some smoke and smell of paint.

Do not stand close to the stove and, as mentioned, air the room. The smoke and smell of paint will disappear after about an hour of operation, however, they are not harmful in any case. The boiler will be subject to expansion and contraction during the lighting and cooling down stages, and may therefore make slight creaking noises. This is absolutely normal as the structure is made of laminated steel and must not be considered a defect. It is extremely important to make sure the boiler does not reach high temperatures straight away, but to increase the temperature gradually using low power at rst. This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.

DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

10-REMOTE CONTROL MAX

GENERAL FEATURES OF THE LCD REMOTE CONTROL

The remote control works at a transmission frequency of 434.5 MHz. Power the product with 3 AAA batteries as follows: Remove the battery compartment cover by pressing and lifting according to the arrow Insert the batteries observing the correct polarity (+) and (-) Close the battery compartment cover.

When the remote control is powered it automatically prompts to set the time. The remote control has a special icon on the display to indicate when the batteries are almost at. If the at battery icon appears, the batteries are almost at and the remote control is about to switch o.

Used batteries contain metals which are harmful to the environment, so they must be disposed of separately in appropriate containers.

GRAPHIC APPEARANCE

In the instructions we will often refer to the indications of the keys shown in the gure. Always keep it at hand for simplicity's sake.

10-REMOTE CONTROL MAX

REMOTE CONTROL OPERATION

General rules

By pressing key A for 1” the product is switched on and o. Key C is used to make all changes. Key E is used to conrm the changes. By pressing key B one selects the product operating mode. Use key D to see the SLEEP setting. Whichever the mode is, press key A briey (or leave the keypad idle for 7”) to go back to the initial display.

INITIAL SETTINGS

Setting the time

Both with the remote control on and o, by pressing keys B+E at the same time for 3” one accesses the time/day setting mode. The hour digits will start to ash; they can be changed with key C. By pressing key E the changes are conrmed.At this point the minutes digits will start to ash. Follow the same modify/conrm procedure, one will then go onto the time display mode (12h or 24h) and nally the day will start to ash. Conrm this data to exit the settings. NOTE: each time the remote control is powered, the time is reset and the display automatically enters the time setting mode.

°C – °F setting

Only with the stove switched o, by pressing key B for 5” one changes the unit of measure of the temperature, from Celsius to Fahrenheit and vice versa.

SETTING THE OPERATING MODE

With the remote control switched on, key B allows to set one of the 4 product operating modes. Figure 1-2-3-4 displays the 4 basic displays, respectively: Manual, Automatic, Timer and Eco mode.

MANUAL Mode (MAN) In this mode one can set the ame power manually (5 levels - act directly on key C to change). Figure 1

AUTOMATIC Mode (AUTO)

In this mode one can set the desired room temperature, and the stove will modulate the ame power automatically to reach the temperature. Figure 2

TIMER Mode (TIMER)

Select this operating mode to switch the product on and o automatically, according to 6 customised time slots (P1 – P6). The following can be set for each time slot:

• Switch-on time

• Switch-o time

• Desired room temperature in the time slot

• Days of the week in which the time slot is active

When the stove is switched on (manually via key A or automatically via a time slot) the product works in the automatic mode described above. A time slot appears automatically when it is active (P1 in gure 3) and the desired temperature is changed according to the value set in the time slot. However, the user can always modify this value as desired and in real time. Refer to the relevant paragraph to learn how to set the time slots.

FIG.3 FIG.5FIG.4

8:20

ECO Mode (ECO)

This mode is activated/disabled with the remote control switched on by pressing key B for 5”. ECO is an automatic mode with the only dierence that if the set temperature is reached and remains so for the following 20 minutes (despite ame modulation), the product switches o and remains on stand-by until the room temperature drops 2 degrees below the desired temperature (and in any case for at least 5 minutes from the last shutdown). The product is then switched on again. Figure 4 If the room is not suciently insulated, ame modulation does not allow the set temperature to stay satised for 20 consecutive minutes and the product will not switch o.

NOTE: It is recommended to use the ECO mode only in well-insulated rooms in order to prevent start-up and shutdown from occurring within short periods of time.

The remote control remains on even when the product is o when in ECO mode, in order to indicate that this shutdown is only temporary. Obviously, if the product is switched o via key A, ECO mode is exited and the product remains o.

Up to 6 automatic start-up and shutdown time slots (E1 – E6) can also be set in ECO mode, which are independent from those of TIMER mode (P1 – P6). If they have been activated, TIMER-ECO appears on the display (gure 5) permanently, even if the remote control is switched o. Refer to the relevant paragraph to learn how to set the time slots.

It detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset value.

PELLET HOPPER TEMPERATURE PROBE

If the temperature exceeds the preset safety value, it immediately stops the product, which must cool down before the stove is restarted.

ELECTRICAL SAFETY

The product is protected against power surges by a general fuse located in the control panel on the back. Other fuses that protect the electronic boards are found on the latter.

SMOKE FAN BREAKAGE

If the fan stops, the circuit board promptly blocks the supply of pellets and the alarm is displayed.

GEAR MOTOR BREAKAGE

If the gear motor stops, the product switches o and the relative alarm is signalled.

TEMPORARY POWER CUT

If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then it restarts.

FAILED START-UP

If no ame lights during start-up, the product will go into alarm conditions.

TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED.

It is possible to relight the product and therefore restore the automatic operation of the probe only after having eliminated the cause of the intervention of the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene according to the alarm message displayed on the appliance.

ALARM ALERTS

In the event an operating anomaly occurs the stove starts switching o due to the alarm and informs the user of the type of fault that has taken place via a 3 digit code which stays displayed on the rear emergency panel. The alarm is indicated permanently by the relative 3 digit code, by a ashing red LED that lights up on the emergency panel and an intermittent sound signal for the rst 10 minutes of the alarm. Read the instructions in the following 2 paragraphs to cancel the alarm status and restore the normal operating mode of the stove. The following table describes the possible alarms indicated by the stove, associated to the respective code that appears on the emergency panel and helpful tips to solve the problem.

Mechanical stove block

The following conditions may cause the mechanical stove block:

• Structure overheating (“A03”)

• Smoke overheating (“A04”)

• During stove operation air has entered the combustion chamber or there is an obstruction

in the chimney ue (“A05”)

The block is signalled on the display and with a sound signal. In this situation the shutdown stage is activated automatically.When this procedure is started, any test operation to restore the system is useless. The display signals the cause of the blockage.

If “A03” appears: the structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation. When the product is suciently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03. Once the alarm is cancelled, the product can be switched on normally. If “A04” appears: The stove switches o automatically. Let the stove cool down for a few minutes and then switch it on again. Check the smoke expulsion and the type of pellets used. If “A05” appears: the door has been left open for too long or a signicant amount of air has entered (e.g. missing smoke fan inspection cap). If these causes are excluded, check and if necessary clean the smoke duct and ue. (it is recommended that this operation is carried out by an MCZ qualied technician.

The product can be switched on again only after having eliminated the cause permanently.

15-CLEANING

EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER

ATTENTION! All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected. Disconnect the product from the 230V power supply before performing any maintenance operation.

The product requires little maintenance if used with certied good quality pellets.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

Before each lighting

Clean and empty any ash or deposits from ash drawer “C” that might obstruct the air ow holes, paying attention to any hot ashes. If the pellets in the hopper run out, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before each start-up. You may only use a vacuum cleaner to remove ash when it is completely cold. In this case, use a suitable vacuum cleaner to remove small sized particles. The quality of the pellets used and user experience will determine the cleaning frequency required.

However, it is recommended not to exceed 2 or 3 days.

REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE IGNITION AND OPTIMAL OPERATION OF YOUR PELLET PRODUCT.

For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the bottom. If good quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the component.

CLEANING THE GLASS

It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specic detergent and clean with a cloth.

ATTENTION! Do not use abrasive products and do not spray the glass cleaning product on the painted parts and on the door gaskets (ceramic bre cord).

15-CLEANING

CLEANING THE AIR FILTER

When the stove is installed, one must t the rear of the stove with the wire mesh air lter, whose purpose is to prevent dirt entering the motor body and the internal sensor. It is recommended to check that the lter is clean every 15/20 days. If needed remove u or the material that has deposited on it. Inspection and cleaning are required more frequently if there are pets in the house. To clean, simply turn the knob that holds the lter on the air intake pipe and remove the lter by turning it in the direction indicated by the arrow. To clean it use a brush or a damp cloth or compressed air.

The lter is made of metallic mesh and is soft and exible to the touch therefore, when cleaning, be careful not to crush or damage it. In the event of breakage it must be replaced. ATTENTION! Never let the stove work without the air lter tted. MCZ cannot be held liable for any damage caused to the internal components if this requirement is not complied with.

15-CLEANING

PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN

CLEANING THE HEAT EXCHANGER AND THE LOWER COMPARTMENT

Half-way through the winter season, but especially at the end, the compartment through which the exhaust smoke passes will need to be cleaned. This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes very dicult to remove it due to the humidity compacting it over time.

CLEANING THE LOWER COMPARTMENT

Open the stove door, remove brazier “A” and clean around it. After that, extract ash drawer “B”, remove the two screws “D” and then plate

“C”. Clean everything with the vacuum cleaner and reassemble the parts. If necessary replace the gasket underneath plate “C”.

We recommend performing this operation after cleaning the upper exchanger.

CLEANING THE LOWER COMPARTMENT - FIGURE: TRAY STOVE

15-CLEANING

CLEANING THE EXCHANGER

Remove the top when the stove is cold. Next, at the front of the stove, near the exchanger, remove plates “r” by loosening screws “q” and loosening screw “x”. On the side of the exchanger, loosen screws “o” and remove plates “p” (one on the right and one on the left). If needed replace the gasket.

ATTENTION! Correctly replace the gasket.

FIGURE: TRAY STOVE

15-CLEANING

The exchanger can now be lifted and the walls of the hearth can be scraped with a sti rod or a bottle brush, so that the dirt falls into the lower compartment.

CAUTION:

the exchanger must be cleaned at the end of the season by an authorised and qualied technician so that any worn

seals may be replaced.

FIGURE: TRAY STOVE

CLEANING THE SMOKE DUCT AND GENERAL CHECKS

Clean the smoke extractor duct, especially around the "T" joints, bends and any horizontal sections. For information on cleaning the ue, contact a chimney sweep.

Check the seal of the ceramic bre gaskets on the door of the stove. If necessary, order new replacement seals from the retailer or contact an authorized service centre to carry out this task.

CAUTION: The frequency with which the smoke outlet system is cleaned depends on the use of the boiler and the type of

installation. We recommend relying on an authorised service centre for end-of-season cleaning and maintenance, as they will carry out all of the previously mentioned work and inspect the stove components.

15-CLEANING

END-OF-SEASON SHUTDOWN

At the end of each season, before switching the product o, it is recommended to remove all the pellets from the hopper with a vacuum cleaner with a long pipe.

When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the power cable for additional safety, especially in the presence of children.

The service fuse may have to be replaced if the control panel display does not switch on when the product is switched on again by pressing the main switch on its side. There is a fusebox on the side of the product, near the power socket. Open the fusebox cover with a screwdriver and replace the fuses if necessary (3.15 A delayed) - seek assistance from an authorised and qualied technician.

CHECKING THE INTERNAL COMPONENTS

ATTENTION! The internal electromechanical components must only be checked by qualied personnel whose technical expertise

includes combustion and electricity.

We recommend that an annual maintenance service is carried out with a scheduled ser vice contract. This service is essentially a visual and functional inspection of the following components: The following is a summary of the checks and/or maintenance that are indispensable for the correct operation of the product.
