That said, we would like to point out that :

• This manual and the technical data sheet, which are also available on our website,, provide all the specific indications and information that are necessary and fundamental for choosing the product, installing it correctly and sizing the smoke outlet system accordingly;
• the Products must be installed, checked and maintained by authorised personnel, according to the instructions in this manual and in compliance with local regulations and the installation and maintenance standards in force in the various countries, in order to have an efficient heating system that is correctly sized according to the requirements of the house,
• if the Products are subjected to thermal stress, with continuous operation for several hours at high power levels (e.g. 3, 4 hours a day at power levels P4 or P5), it is recommended that cleaning be carried out more often and that the interval between ordinary maintenance operations be reduced, depending on the operating condition of the Product. Please also note that in these working conditions, the risk of premature wear of the product increases, especially in the parts exposed to the direct heat of the flame (e.g. the combustion chamber), whose original condition could be altered and damaged, which could also cause noise during operation of the product due to mechanical expansion.

The manufacturer accepts no responsibility for any failure to comply with the above instructions.

INSTALLATION

PREAMBLE
The installation of the heating system (generator + combustion air supply + exhaust system + any hydraulic/aerodynamic system) must be carried out in compliance with the laws and regulations in force 1, by an authorised technician, who must provide the plant manager with a declaration of conformity of the system itself and who will assume full responsibility for the final installation and correct operation of the resulting product.
The manufacturer declines all responsibility for installations that do not comply with the regulations and laws in force and for inappropriate use of the appliance.
In particular, it is important to ensure that :

• the environment is suitable for the installation of the appliance (load-bearing capacity of the floor, presence or possibility of installing a suitable electrical/hydraulic/air-conditioning system if necessary, volume compatible with the characteristics of the appliance, etc.);
• the appliance is connected to a smoke outlet system that is correctly dimensioned in accordance with standard EN 13384-1, is soot fire resistant and respects the prescribed distances from combustible materials indicated on the rating plate;
• there is an adequate flow of combustion air for the appliance;
• the other combustion appliances or extraction devices installed do not depressurise the room where the product is installed by more than 4 Pa in relation to the outside (for sealed installations only, a maximum of 15 Pa of negative pressure in the environment is permissible).

The national regulations governing the installation of domestic appliances are 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 scrupulously respect the safety distances from combustible materials to avoid serious damage to people’s health and the integrity of the home.

The appliance must be installed in such a way as to ensure easy access for maintenance of the appliance itself, the smoke outlet pipes and the flue pipe.
Always maintain an appropriate distance and protection to avoid the product coming into contact with water.

The stove must not be installed in premises where there is a risk of fire. With the exception of airtight installations, the coexistence in the same room or in adjoining rooms of continuous or discontinuous liquid fuel appliances that draw combustion air from the room in which they are installed, or of type B gas appliances intended for space heating, with or without production of domestic hot water, is also prohibited.

Leak-tight installation means that the product is certified leak-tight and that its installation (combustion air ducting and connection to the chimney) is hermetically sealed with respect to the installation environment.

A sealed installation does not consume oxygen from the environment by taking all the air from the outside environment (provided the ductwork is correctly designed) and the products can therefore be placed inside all homes that require a high degree of insulation, such as «passive houses» or «energy- efficient houses». Thanks to this technology, there is no risk of smoke emissions into the environment, and there is no need for free air intakes in the installation room or for relative ventilation grilles. As a result, there will be no more cold air flows in the environment, making it less comfortable and compromising the overall efficiency of the system. The sealed stove, which can also be installed in a watertight system, is compatible with the presence of forced ventilation or rooms that may be at low pressure relative to the outside.

Air intake
An adequate external air intake must be provided to supply the combustion air required for the product to operate correctly. The air supply between the outside and the installation room can be via a free air intake or by channelling the air directly to the outside 3.

The free air intake must:

• be built close to ground level
• always be protected by an external grille so that it cannot be obstructed by any object
• have a total free area of at least 80 cm² (net of grille)

The presence in the same room of other extraction devices (for example: vmc, electric fan for extracting stale air, kitchen hood, other stoves, etc.) can create a negative pressure in the environment. In this case, with the exception of airtight installations, it is necessary to check that with all the equipment switched on, the installation room is not subjected to a negative pressure of more than 4 Pafrom the outside. If necessary, increase the air intake cross-section.  The air required for combustion can be ducted outside by connecting the outside air intake directly to the combustion air inlet, which is usually at the rear of the appliance. The pipe must comply with the following dimensions (each 90° bend is equivalent to one linear metre):

If the combustion air is ducted to leaky products, ensure that the installation room is not subjected to a negative pressure of more than 4 Pafrom the outside, otherwise provide an additional air intake in the room.

Fittings for the smoke outlet system

The flue system is particularly important for the correct operation of the appliance and must be correctly dimensioned in accordance with standard EN 13384-1.
It must always be carried out/adapted/checked by a legally authorised operator and must comply with the regulations in force in the country where the appliance is installed.
The Manufacturer declines all responsibility in the event of malfunctions attributable to a poorly dimensioned or non-compliant smoke outlet system.

Flue pipes (flue connection)
The flue is the pipe that connects the appliance to the flue.
In particular, this smoke connection must comply with the following requirements:

• comply with product standard EN 1856-2;
• its cross-section diameter must be constant and at least identical to that of the appliance outlet from the fireplace outlet to the flue connection;
• The length of the horizontal section must be as short as possible and its projection in plan must not exceed 4 metres;
• horizontal sections must have a minimum upward slope of 3%;
• changes of direction must be at an angle of no more than 90° and be easily inspected
• the number of changes of direction, including that for entry into the flue, and excluding the T in the case of side or rear exit, must not exceed 3;
• it must be insulated if it passes outside the installation room
• it must not pass through rooms where the installation of combustion appliances is prohibited.
• It is forbidden to use flexible metal tubes, fibre cement or aluminium pipes;

In all cases, the flues must be sealed against combustion products and any condensate. To achieve this, it is recommended to use tubes with a silicone gasket or similar sealing devices that can withstand the operating temperatures of the appliance (e.g. T200 P1) and which, when the gaskets are removed, are still certified T400 N1 G.

Flue pipe (chimney or flue liner)
When constructing the flue, the following requirements must be complied with:

• comply with the applicable product standard (EN 1856, EN 1857 EN 1457, EN 1806, EN 13063, etc.);
• be made of materials that are suitable for withstanding normal mechanical, chemical and thermal stresses, and have adequate thermal insulation to limit the formation of condensation;
• have a predominantly vertical course and be free of bottlenecks along its entire length;
• be correctly spaced, leaving an air gap, and insulated from combustible materials;
• the flue inside the home must be insulated and may be inserted into a skylight, provided it complies with intubation regulations;
• the flue channel must be connected to the flue pipe by means of a «T» fitting with an examinable collection chamber to collect any soot and potential condensate;
• when the sizing provides for operation in humid conditions, a suitable collection system and condensate drain must be installed.

It is recommended to check, in the nominal data of the flue, the safety distances to be respected 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 flue or to a flue in common (*) with other combustion appliances or with hood evacuation systems.
It is forbidden to use the exhaust system directed towards the wall or towards enclosed spaces or any other form of exhaust that is not provided for by the regulations in force in the country of installation.

Chimney terminal
The ridge, i.e. the end of the flue, must meet the following requirements:

• the cross-sectional area of the flue outlet must be at least twice the internal cross-sectional area of the chimney;
• prevent rain or snow from penetrating;
• ensure that flue gases escape even in windy conditions (windproof ridge);
• the outlet height must be outside the backflow zone (*) (refer to national regulations to identify the backflow zone);
• it must always be built away from aerials or satellite dishes and must never be used as a support.

(*) unless there are specific national derogations (clearly specified in the relevant language instructions) which, under appropriate conditions, allow this; in this case, the product/system requirements laid down in the regulations/technical specifications/legislation in force in that country must be strictly complied with

INSTALLATION EXAMPLES 4 (DIAMETERS AND LENGTHS TO BE SCALED)

1. Installation of the flue pipe with a hole for the passage of the pipe increased by:

2. 100 mm minimum around the pipe if it communicates with non-flammable parts such as cement, bricks, etc. or

3. 300 mm minimum around the pipe (or as specified in the nominal data) if it communicates with flammable parts such as wood, etc.
   In both cases, suitable insulation must be inserted between the flue and the floor.
   We recommend that you check and comply with the flue pipe ratings, particularly the safety distances from flammable materials.
   The above rules also apply to holes in the wall.

4. Old flue, surrounded by an external door to allow the chimney to be cleaned.

5. External flue made exclusively from insulated stainless steel pipes, i.e. double-walled and firmly anchored to the wall. With a windproof chimney terminal.

UNPACKING

INSTRUCTIONS FOR DISPOSAL OF PACKAGING
The material from which the appliance is packaged must be disposed of correctly, with the aim of facilitating its collection, reuse, recovery and recycling where possible.
The table below lists the components that may make up the packaging and the corresponding instructions for correct disposal.

AIR OXIDIZER

COMBUSTION AIR INLET
AHLMA stoves can be connected directly to the outside to supply combustion air or fresh air.
This connection is not compulsory for a ventilated room in accordance with D.T.U 24.1.
In the case of an airtight house (BBC or RT 2012 compliant), the direct connection to the outside with a 120 Ø duct can be made from underneath (crawl space for example) or from behind (pre-cut passage in the rear cladding sheet).

NEVER BLOCK THE COMBUSTION AIR INLET.

FLUE GAS

FLUE CONNECTION
It is recommended to connect the product to the flue using aluminised steel pipes and elbows capable of withstanding the high tempe-ratures reached in this area and the corrosion caused by the flue gases. These fittings are available in different sizes on request (see our catalogue) and simplify installation by simply fitting them together.
The flue connection can be top or rear.
To make the connection, proceed as follows:

• Unscrew the rear cover
• Swap the rear cover over the top hole
• proceed to connecting to the flue

Any increase in the cross-section of the connection must be made directly above the product hood, and not along the flue.
Once the installation is complete, the flue connection must be insulated with a ceramic fibre insulation mat or a material that can withstand a temperature of at least 600°C.

CHOICE OF FUEL

The information in this chapter refers explicitly to the Italian installation standard UNI 10683. In all cases, the standards in force in the country of installation must be complied with.

THE FUEL
Here are a few useful tips on how to use the product correctly

• Burn only natural, untreated wood with a maximum moisture content of 20%, which corresponds to wood that has been cut and properly dried for 2 years.
• All types of wood are suitable, both hard and soft: beech, maple, oak, birch, acacia, fir, pine, larch, etc.
• Always use wood of the right calibre and in pieces, as the whole trunk prevents air from getting inside.
• Always burn wood horizontally, not upright.
• When reloading, use the quantity of wood indicated by the manufacturer and do not reload one piece after another, as the flame will never reach the temperature required for proper combustion.
• Do not insert a larger quantity than indicated to avoid excessive flames and high smoke and wall temperatures.
• The thickness and length of the wood must always comply with the manufacturer’s instructions: the length (25 or 30 cm) depends on the dimensions of the hearth plate in the combustion chamber.

Here are some useful tips on storing wood correctly:

• stored wood must already be cut for use.

• optimum drying requires a minimum of 2 years (longer drying times would not result in higher drying).

• Wood must be cut in winter and stored outside in summer.
  Storage must be carried out :

• in a well ventilated and aerated place

• in a covered area away from rain and sunlight, as the wood will lose its quality(DO NOT cover the wood with tarpaulins that touch the ground, as they will have the effect of a tightly closed lid and the wood will become even wetter).

• so that the wood is not laid directly on the ground but at a distance of around 20-30 cm to prevent it rotting.

• outdoors if possible, otherwise in well-ventilated rooms or cellars to avoid mould formation (always leave the window open!).

• Wood must always be stored at a safe distance from the combustion appliance – fire and safety regulations must always be complied with.

FUEL: Wood
To get the maximum performance from your product, it’s essential to use wood with the right characteristics.
We recommend using oak-beech-oak-robin-oak firewood or compressed non- coniferous logs. These have a high calorific value and must be used with care to avoid overheating, which can damage the product. Fuels such as poplar-pine- lime-chest-nut-eucalyptus-myth are soft woods: they have a low calorific value. For all the types of wood listed, the moisture they contain is fundamental.
By lighting a fire with a higher humidity level, most of its energy content will be used to dry out the water. Using damp wood also leads to poor combustion and deposits of soot and tar in the flue, which in the worst case can cause fires. This will also have the disadvantage of causing soot deposits on the product’s glass and disturbing neighbours.

Warning!
It is strictly forbidden to use fossil fuels, impregnated, painted or glued wood, chipboard, plastic or coloured printed documents as fuel. All the above products generate hydrochloric acid or heavy metals during combustion, which are harmful to the environment and the home.
Hydrochloric acid can also corrode the steel or masonry of the flue.

The table below shows the moisture content and calorific value of a burnt 1 kg log.
The optimum condition of use with a drying time of 24 months will correspond to a humidity of 16% and a corresponding energy of 15,350 kJ/kg.
A significant loss of 25% is obtained when the wood has a moisture content of 29% and an energy of 12,200 kJ/kg.

• The type of wood: it is recommended to use only virgin, uncontaminated wood, and to find out about the properties of the wood and how to dry it properly;
• Moisture: only dry wood should be used, as damp wood does not heat up well, reduces the efficiency of the appliance and produces polluting emissions;
• Dimensions: split wood is preferable to round wood, and logs of uniform dimensions, ideally medium or small (25-33 cm in length, 5- 15 cm in diameter).

CONCLUSION
The table determines the energy loss of wood and can be summarised as follows: Losing 25% of energy is equivalent to losing 1 log (1 kg) out of every 4.

• Remove components that could burn (instructions and various adhesive labels) from the product firebox and door.
• Remove the adhesives from the glass ceramic, otherwise the high temperature may melt them and cause irreparable damage to the glass.
• The product can be placed in a corner or against a wall and can be installed at any height by building a suitable support.
• Avoid touching the product during the initial ignition, as the paint will finish drying and harden during this phase. It is recommended to ensure that the room is well ventilated during the initial lighting, as the product will give off a little smoke and varnish smell, which is perfectly normal!
• If necessary, refresh the paint with a spray can of the corresponding colour.
• Do not stand near the product and, as already mentioned, ventilate the room well. Smoke and the smell of paint will disappear after about an hour’s operation, but they are not harmful to health.
• The product will tend to expand or contract during the ignition and cooling phases, and may therefore make a slight squeaking noise.
• This phenomenon, which is completely normal given that the structure is made from rolled steel, should not be considered a defect.

ONLY FOR THE FIRST IGNITION
It is extremely important not to overheat the product immediately, but to bring it up to the right temperature gradually.
This prevents damage to the welds and the steel structure.

FUNCTION TEST

WARNING!!
BEFORE CARRYING OUT ANY OTHER ASSEMBLY OPERATION ON THE CLADDING, CARRY OUT A GENERAL INSPECTION OF THE PRODUCT IN ACCORDANCE WITH THE FOLLOWING INSTRUCTIONS:

Light a moderate fire to check that there are no smoke/soot leaks from the flue connection.

THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR DAMAGE TO THE CLADDING IF THE ABOVE PREVENTIVE CHECKS ARE NOT CARRIED OUT AND IF IT IS NECESSARY TO DEMOLISH THE CLADDING IN ORDER TO CARRY OUT REPAIRS OR ADJUSTMENTS.

STEPS FOR THE FIRST TEST IGNITION

• Make sure you have fully read and understood the contents of this manual.

• Remove components that could burn (instructions and various adhesive labels) from the product firebox and door.

• Remove the adhesives from the glass ceramic, otherwise the high temperature may melt them and cause irreparable damage to the glass. In this case, the manufacturer will not recognise the guarantee on the glass.

• Open the combustion air regulator as far as it will go (lever fully to the left).

• Place small pieces of very dry wood (15/20% humidity).

• Light a moderate fire, without overheating the structure. If the fireplace is new, it may emit an odour due to the presence of an oily patina and excess paint, which disappears after it has been lit a few times.

• If necessary, leave the door slightly open so that the wood can burn better and any internal moisture can dry out. When the flame is stable, close the door completely.

• A high percentage of humidity causes condensation in the product, impairing the draught and generating smoke and a considerable deposit of soot in the firebox, on the glass of the firebox door and on the flue, with a possible risk of the glass catching fire; a high percentage of humidity also results in a much lower overall efficiency.

• Using damp or treated wood gives off more smoke than normal, which can dirty the glass more quickly. The low performance of the chimney can also affect the cleanliness of the glass, as the smoke remains in the combustion chamber for longer than normal.

• Do not use treated (painted or lacquered wood) or non-compliant (plastic or derived products) fuels, which may emit toxic or polluting substances.

• Do not burn waste.

• The gases produced by combustion resulting from the use of unsuitable fuel can cause damage to the product, the flue, pollution and harm to your health.

• The quality of the flame and the cleanliness of the internal surfaces of the product (white Alutec and clean glass) are an excellent indicator of the internal temperature of the appliance (*). In fact, the higher the internal temperature, the better the performance and cleanliness of operation; the best operating performance is achieved when a sufficient bed of glowing embers accumulates at the base of the firebox to maintain an even, high internal temperature.
  Once the ignition and chamber overheating phase is over, the flame can be lowered by turning the flame control knob to the «CLOSED» position. The following loads must be loaded with the SPECIFIED quantity of wood specified in the product’s TECHNICAL characteristics.

• (*) The performance and achievement of internal temperatures and the resulting cleanliness are strongly influenced by the quality and humidity of the wood (<20%) and by the quality and draught of the flue (>12 Pa when hot)

FUEL LOADING
To load the fuel as usual, simply open the firebox door using the cold hand provided. During use, the metal structure and glass reach high temperatures, suitable thermal protection should therefore be used (e.g. gloves). During normal use, always keep the firebox door fully closed, as intermediate positions cause abnormal combustion (forging effect), rapid consumption of wood and may also cause smoke to escape due to the high firebox temperature. Only open the door for fuel loading operations, and only for short periods. Maximum efficiency and optimum product performance are achieved with the door closed, because the airtightness of the combustion chamber and the calibrated oxygen inlet allow efficiency levels to be increased.

To obtain the rated output and optimum combustion conditions, insert the load of wood and observe the refuelling interval indicated in the technical data table.

COMBUSTION CONTROL

Air inlet control lever
The stove is equipped with an air inlet control that regulates the combustion of the wood and thus influences the output of the stove. The stove is set to maximum output when the air intake control is pulled fully in (MAXI position).

Ignition procedure

• Set the air inlet control to the MAXI position;
• Pull the ash removal control towards you as far as it will go;
• Place 4 to 5 crumpled sheets of newspaper on the bottom of the heater;
• Place several pieces of small wood such as fir or wood from a crate, etc. on the paper;
• Set fire to the paper in several well-spaced areas around the bottom of the heater and close the door;
• Wait a few minutes for embers to form, group them towards the centre and place several small, dry logs;
• When the logs are sufficiently burnt (about ½ hour after lighting), group the embers towards the centre and load with logs;
• Wait a further 5 to 10 minutes until the logs are well ignited, then adjust your stove to suit your preference

COMBUSTION CONTROL

WARNING: Failure to follow this procedure could result in the glass becoming clogged or your stove going out.
When the stove is in the MINI position, the amount of air inside is very limited (idle position). As the secondary air supply is the key to keeping the glass clean, we strongly recommend that you never set the air inlet control to the MINI position for more than 20 minutes, to avoid clogging the stove or the glass. On the other hand, if the glass starts to get dirty, we recommend that you restart the fire and set the control to MAXI position, which will automatically clean the glass using the pyrolysis effect.

Reloading procedure

• Open the stove door and reload with wood;
• Close the door and set the air inlet control to MAXI position;
• Wait a few minutes for the logs to ignite sufficiently, then reposition the air inlet control to obtain the desired output.

Adjusting the air inlet control according to the desired output or tempo:

__

Reloading wood

| for 5 to 10 minutes| MAXI
beyond| depending on power required
Maximum speed (*)| MAXI
Allure mini| half distance between MINI and 50%

(*): The maximum speed is recommended for a few minutes after reloading the wood or for a few hours a day in very cold weather, although you should be aware that this setting will lead to your wood being over-consumed.

FIREPLACE DOOR

DOOR OPENING
Handling the stove door:
The stove door handle must be handled with a protective glove (supplied with your appliance) and always with care. For greater safety, the door is equipped with a system that keeps it open, so you can recharge your stove in better conditions.
If the door does not stay open at 90°, you can adjust the position of the door stop screw shown below. Loosen the clamping nut, then turn the screw.

Handling the firewood door:
The stove is equipped with a log door that opens by push-button or «Push & Pull» system. To open the door, simply press on the right-hand side of the door. A slight «click» is then heard, indicating that the door is open.
To close it again, simply push the door until it clicks again, meaning that you can release the door because it’s closed.

WARNING: It is strictly forbidden to store anything easily flammable in the lower part of the stove (newspaper, crates, firelighters, etc.).

CLEANING

WARNING!
All cleaning operations on all components must be carried out with the product completely cool; ensure that the ashes are extinguished, use personal protection safety devices and use appropriate equipment for maintenance.

CLEANING BY THE USER
ASH CLEANING
It is recommended to clean the hearth plate thoroughly to ensure correct combustion. To remove the ashes from the fireback, use a metal shovel and, if necessary, a brush to place the ashes in non-flammable containers for transport.

GLASS CLEANING
To clean the glass, you can use special products (see our catalogue), a cloth soaked in a solution of water and ammonia or a little white ash and a sheet of newspaper.

WARNING!
Do not spray on painted parts or door seals (ceramic fibre cord)

Never apply the cleaner directly to the glass, and above all never leave the product to act. This type of application will systematically lead to damage to elements (paint, screen printing) not covered by the warranty.

• Step 1: Soak a soft cloth and spray your product (liquid or foam) directly onto it.

• Step 2: Scrub the glass thoroughly to remove all the dirt. Repeat steps 1 and 2 if necessary.

• Step 3: Soak a second clean cloth or paper towel in water.

• Step 4: Rinse the glass, taking care to wipe the entire surface with a cloth soaked in water.

• Step 5: Dry your glass to avoid streaks and premature soiling the next time you light it.

CLEANING REFRACTORY WALLS
They do not require cleaning, as this material does not absorb soot but repels it when the fire is hot. After the ignition phase, during which the fire tends to blacken, the refractories tend to turn white again, from the base of the flame, when the combustion chamber is at the right temperature (~ 400°C).
If this phenomenon does not occur, it may be caused by:

• Damp or resinous wood that does not release enough heat or that dirties the combustion chamber
• Poor performance of the chimney, causing the smoke to linger too long in the combustion chamber, fouling the firebox
• Poor chimney performance, which prevents the product from achieving high yields and, consequently, the refractories from reaching the appropriate temperatures.
• Never clean the refractory with a damp cloth or anything else, as it could become stained.
• At most, use a dry brush to remove large deposits of soot.
• In view of the aforementioned warnings and indications, the absence of «whitening» should not be considered a defect.

CLEANING BY A SPECIALIST TECHNICIAN

FLUE CLEANING
It is recommended to clean the flue pipe mechanically at least once a year. Excessive deposits of unburnt slag can cause problems with flue smoke outlet and flue fires. To clean the appliance flue, remove the smoke deflector: to remove it correctly, lift it at the front while simultaneously moving it forward to release it from the rear support brackets.

CLEANING THE FLUE
The flue pipe must always be kept clean, as deposits of unburnt soot or oil reduce the cross-section and block the draught, compromising the correct operation of the product and, if present in large quantities, can catch fire.
The flue and chimney terminal must be cleaned and inspected by a qualified chimney sweep at least once a year. After the inspection/maintenance, obtain a written declaration confirming that the system is operating safely. Failure to clean compromises safety.
