Warning: this appliance is designed and prepared to work with the types of fuel, degree of humidity of the fuel, fuel loads, fuel load frequencies, flue draught and system of installation indicated in this Instruction Book. Failure to respect these conditions may lead to problems with the appliance (deterioration, shorter useful life, etc.) which are not covered by the Lacunza warrant).
To obtain these data, tests have been done on the standards AS/NZS 4012 (2014), AS/NZS 4013 (2014) and AS/NZS 2918 (2018), with eucalyptus wood.

INSTRUCTIONS FOR THE INSTALLER

Warning to installers
All local and national regulations, including all those referring to national and European standards, must be observed when installing the appliance.
Installation of the appliance must be performed by an authorised installer.
An incorrectly installed appliance may lead to serious incidents (fires, creation of harmful gases, deterioration of nearby fixtures, etc.).

Lacunza’s liability is limited to the supply of the material and does not include installation of the appliance.

Room for installation

Ventilation of the room
The appliance needs to consume oxygen (air) in order to work properly. Ensure a suitable air supply in the room in which the appliance is fitted. This quantity of oxygen is additional to the oxygen that we need in order to breathe (air renewal).
In order to ensure the high quality of the air you breathe and to avoid potential accidents resulting from high concentrations of the gases produced by combustion (mainly carbon dioxide and carbon monoxide), it is absolutely crucial to ensure the suitable renewal of the air in the room in which the appliance is fitted.
For the installation of its appliances, Lacunza recommends an additional section for these openings. One of these two grilles must be situated high up in the room (at  less than 30 cm from the ceiling) and the other one low down (at less than 30 cm from the floor). Both grilles must open outdoors in order to renew the air in the room with fresh air.
The minimum section that each of these grilles must have depends on the nominal output of the appliance in accordance with the following table:

Output of the appliance (kW)| Minimum additional section

of each of the grilles (cm 2)

---|---
P ≤ 10kW| 70
10 < P ≤ 15| 90
15 < P ≤ 20| 120
20 < P ≤ 25| 150
25 < P ≤ 30| 180
30 < P ≤ 35| 210
P > 35| 240

In the case of appliances on which it is possible to pipe combustion air in from outdoors, the specifications described in the Table above are not necessary.
The appliance must always be used with the door(s) closed.
In rooms equipped with Controlled Mechanical Ventilation, the system extracts and renews the ambient air; in such cases, the room is at slightly low pressure and it is necessary to install a nonclosable outside-air inlet with a section of at least 90 cm².

Location of the appliance in the room
Choose a location in the room which favours good hot-air distribution by convection and radiation.
WARNING!: The appliance must be placed on a raised support or bench that allows the passage of air for combustion under of it.

Installation of the appliance

. Floor
Make sure that the base can withstand the total constructed weight of the appliance and its casing.
The apparatus should not be placed on combustible material.

Nickel 800
A minimum 520mm deep x 720mm wide x 50mm thick floor protector (Skamol board) should be used under the appliance base when installing the appliance (see joint AS/NZS 2918:2018 3.3.2). A minimum 450mm deep x 1110mm wide x 36mm thick floor protector (compressed board) should be used in front of each of the appliance doors and be placed centrally in the 1110mm width. The Thermal resistivity of the 50mm skamol board floor protector is 0.74m².K/W. The Thermal resistivity of the floor protector is 0.16m².K/W for 36mm thick compressed board sheets. Minimum air gap of 40mm must be maintained under the appliance base to the Skamol floor protector.

Nickel 1000
A minimum 510mm deep x 1015mm wide x 50mm thick floor protector (Skamol board) should be used under the appliance base when installing the appliance (see joint AS/NZS 2918:2018 3.3.2). A minimum 600mm deep x 1320mm wide x 36mm thick floor protector (compressed board) should be used in front of each of the appliance doors and be placed centrally in the 1320mm width. The Thermal resistivity of the 50mm skamol board floor protector is 0.74m².K/W. The Thermal resistivity of the floor protector is 0.16m².K/W for 36mm thick compressed board sheets. Minimum air gap of 50mm must be maintained under the appliance base to the Skamol floor protector.

Safety distances
Be sure to respect the appliance installation distances from combustible materials.

Bear in mind that it may even be necessary to protect non-combustible material in order to prevent breakage, deformation, etc., as a result of overheating if the non-combustible material is not designed to withstand high temperatures.

Checks before lighting for the first time

• Make sure that the glasses are not broken or damaged.
• Make sure that the flueway is not obstructed with packing or loose parts.
• Check the deflectors are correctly positioned.
• Make sure that the airtight joints on the flue circuit are in perfect condition.
• Make sure that the doors close properly.
• Make sure that all moving parts are fitted in place.

Height adjustment and levelling the appliance
The appliance must be perfectly level, horizontally and vertically, both at the front and on the sides (use a spirit level).
The appliance has adjustable legs with which to adjust its height.
The legs can be adjusted using a 24mm spanner.

Casing
If the customer would like to coat the appliance, the following instructions should be followed.
Make sure that the material around the appliance is not flammable or likely to deteriorate as a result of heat (wallpaper, carpet, plastic-based casing, Silestone, etc.).
The image below gives an example of how the appliance can be encased properly:

Key to casing diagram:

1. Ceiling
2. Flue
3. Incombustible material (Inner hood insulation)
4. Insulating deflector made of incombustible material
5. Wall
6. Fresh-air inlet (1,000 cm2) 7 Hot-air outlet (1,000 cm2)

Figure No.9 – Exterior diagram of the casing

In order to enable suitable air circulation and correct operation, the casing must have a fresh-air inlet with a minimum section of 1,000cm2 beneath the level of the actual appliance and a hot-air outlet measuring at least 1,000cm2 above it (just before the insulating deflector inside the casing). These inlet and outlet sections must ensure air renewal in such a way as to avoid damage to parts inside the hood due to excess temperature.
This specification must be observed regardless of the type of installation chosen (with or without forced ventilation, combustion air from indoors or outdoors, directed hot-air outlets with or without pipes, etc.). A further hot-air ventilation grille is also recommended between the insulating deflector on the hood and the ceiling.

As well as this, the hood/closure should have a free opening of at least 100 cm2 for the intake of air for combustion.

Warning: on appliances on which it is possible to pipe air to the firebox, the hood requires a further air inlet at the bottom, in addition to the 1,000cm2 inlet, if the air supply comes from the room in which the appliance is fitted.
On non-central-heating appliances (without back boiler), Lacunza does not recommend enveloping the outside of appliances with insulation.
Never completely block off the lateral ventilation grilles of the fairing.
The installer must fit the necessary inspection accesses (trap doors, hatches, etc.) so that everything inside the hood that may need maintenance work or replacement can be accessed at any time, e.g. counterweight system, hydraulic components, heating circuit safety
components..

Connection to the flue
The appliance must be connected to the chimney flue using special piping designed to resist the products of combustion (e.g. stainless steel, enamelled steel, etc.).
To connect the flue to the socket flange, insert the piping inside the flange and seal the joint with fire sealant or fire cement to make it completely airtight.
The installer must ensure that the pipe connected to the appliance is well secured and there is no chance of it coming free from its housing (e.g. as a result of dilatation due to temperature, etc.).

Piping air to the firebox
On this model, it is possible to pipe air to the appliance for combustion straight from outdoors. We recommend that, if possible, air be drawn from outdoors for combustion via a non-closable pipe with a diameter of 120mm leading to the nozzle on the bottom-front of the appliance.
If the tube is straight, it can have a maximum of 12 meters in length. If you use accessories like elbows, you must subtract the total length (12 meters) 1 meter for each accessory used.
This is the best option because it means that draughts are not created in and oxygen is not consumed from the room in which the appliance is fitted. A further advantage is that there is no danger of downdraught which may hinder the correct updraught of the appliance when an extractor or mechanical ventilation appliance is used in the same room as the central-heating appliance or in another one alongside it.

If this is not possible, ensure that the appliance receives air for combustion via the relevant grille at the bottom of the hood (in addition to the hood ventilation grilles).

Exterior Frame. Removal and assembly

To fit the frame, proceed as follows:

• Bend all the tabs lacated in the upper and lower part of the frame, as shown in te picture.

• Insert the frame in the appliance pressing.

Chimney flue
The chimney flue must comply with present standards on the installation of chimneys.
In rooms equipped with Controlled Mechanical Ventilation, the ventilation outlet must never be connected to the flue.
The appliance must always have its own chimney flue, never sharing a chimney flue with another appliance.

Type of flue
The flue must be made of special material designed to resist the products of combustion (e.g. stainless steel, enamelled steel, etc.).
Non-central-heating appliances (without back boiler) require an insulated, double-sleeve flue only on those sections that run outdoors or through cold areas. Single piping can be used inside the building, the heat of the gases serving to heat rooms, insulating only those sections where excess temperature may cause damage.

If the chimney is constructed, then it is necessary to pipe and insulate it to ensure correct updraught.

• The diameter of the pipe must be the same as the diameter of the flue socket on the appliance over its entire length in order to ensure correct operation.
• The flue must prevent the entry of rainwater.
• The flue must be clean and airtight over its entire length.
• The flue must be at least 5m tall and the chimney cap must not hinder the free release of gases.
• If the flue tends to suffer from downdraught, then it is necessary to fit an effective anti-downdraught cowl, a static cowl or a smoke extraction fan, or reshape the chimney.
• Never make 90º bends, due to the great loss of draught they cause, and reduce 45º bends down to an absolute minimum. Each 45º bend is equivalent to a 0.5m reduction in flue length. Horizontal flue sections should not be installed because they cut updraught a great deal.
• The appliance is designed to operate under controlled draught conditions. The appliance must operate at a chimney draght of between 12Pa and 15Pa. To ensure this draught, an automatic draught moderator must be installed in the flue. Uncontrolled draught operation  can lead to quick damage of the appliance, which will not be covered by the warranty.
• The flue must not rest its weight on the appliance, as this could damage the worktop.
• Bear in mind that high temperatures may be reached in the flue, meaning that it is essential that insulation be enhanced in sections in which combustible material is present (wooden beams, furniture, etc.). It may even be necessary to protect non-combustible material in order to prevent breakage, deformation, etc., as a result of overheating if the material is not designed to withstand high temperatures.

It must be possible to clean the entire flue, no sections being left inaccessible for cleaning purposes.

Chimney crown
The upper end of the chimney must clear the roof, the roof ridge or any obstacle located on the roof by at least 1m.

The chimney crown must clear the highest point of any neighbouring building or obstacle located within a 10m radius of the chimney outlet by more than 1m.

The chimney crown must clear any neighbouring building or obstacle located within a radius of 10m to 20m from the chimney outlet.

INSTRUCTIONS OF USE

The manufacturer accepts no liability whatsoever for damage caused to parts as a result of the improper use of non-recommended fuels, modifications made to the appliance or how it is installed. Only use original replacement parts.

All local and national regulations, including those referring to national and European standards, must be observed when using the appliance.
Heat is diffused by radiation and convection via the front and exterior of the appliance.

Fuel
This appliance must not be used as an incinerator. Do not use non-recommended fuels.

• Use dry logs (max. 16% humidity), cut at least 2 years ago, clean of resin and stored in a sheltered, ventilated place.
• Use hard woods with high calorie values and good ember production.
• Large logs should be cut to useable lengths before being stored. The logs  should have a maximum diameter of 150mm.
• Finely-chopped wood produces greater heat output, but also burns more quickly.

Optimum fuels:

• Beech, hardwood and eucalyptus logs.

Other fuels:

• Oak, chestnut, ash, maple, birch, elm, etc.
• Resinous wood may mean that the appliance and the flue need to be cleaned more often.

Non-permitted fuels:

• All types of coal and liquid fuel.
• “Green wood”. Green or damp wood reduces the performance of the appliance and leads to soot and tar build-up on the inner walls of the flue, obstructing it.

“Recovered wood”. The burning oftreated woods (railway sleepers, telegraph posts, plywood, fibreboard, pallets, etc.) quickly blocks the system (soot and tar build-up), harms the environment (pollution, smells) and may lead to deformation of the firebox due to

• overheating.
• All materials which are not wood (plastic, spray cans, etc.).

Green and reprocessed wood may cause chimney fires.

The graph below shows how the humidity of firewood affects its heat output:

Lighting
Use of the appliance in warm weather (warm days, early hours of the afternoon on sunny days) may lead to lighting and updraught problems.
Certain weather conditions, such as fog, ice, humidity entering the flue, etc., may hinder sufficient updraught in the flue and lead to suffocation.
Proceed as follows in order to light the appliance satisfactorily:

• Open the firebox door(s) and open all the firebox air-intake inlets to the full.
• Place paper or a firelighter and some wood chips in the firebox.
• Light the paper or firelighter.
• Leave the door slightly ajar, the width of two or three fingers, for about 15 minutes until the glass warms up.
• The first time the appliance is lit, the fire should be gentle to allow the parts of the appliance to dilate and dry.

Important: The first time it is lit up, the appliance may give off smoke and strange smells. This is not a cause for concern. Open an outdoor window to ventilate the room during the first few hours of operation.
If you notice water around the appliance, this is produced by the condensation of the moisture in the wood on lighting the fire. This condensation will no longer appear when the appliance has been lit three or four times and has adapted to its flue. If it does not disappear, then check the flue draught (length and diameter of the flue, flue insulation, airtightness) and the humidity of the wood used.

Loading fuel

• In order to load firewood, open the firebox door gently, preventing the sudden entry of air to the firebox so that smoke does not enter the room that the appliance is installed in.
• Perform this operation with the glove to prevent burns to the hands.
• Always load with medium primary air settings (see table in section 1.1).
• For minimum burning (e.g. at night), use thicker logs.
• When the firebox is loaded, close the door.

Be careful when placing logs in the firebox on appliances with vermiculite interiors. Vermiculite is a fragile material and may crack if knocked.

Operation
The appliance should be operated with the doors closed.

For safety reasons, never close all the appliance’s combustion-air intakes.

Air intake
By opening this inlet, air enters the firebox in the following sequential way:

1. 1º- Through the double combustion holes on the sides of the combustion chamber.
2. 2º- At the top of the combustion chamber door.
3. 3º- Finally, air is introduced into the combustion chamber through the grille.

IMPORTANT: Keeping the secondary-air intake open (the air that enters the firebox via the top of the firebox door) helps keep the door glass cleaner for longer.

IMPORTANT: The appliance is exposed to extreme changes in temperature and may, as a result, make noises when in operation. These noises are a natural result of expansion/contraction of the parts which make up the appliance. Do not be alarmed by noises of this kind.

In order to obtain maximum output, open all the air intakes to the firebox and in order to obtain minimum output, tend towards closing them.
For normal use, we recommend you the air Intake 50 % open.

• High burn rate: The appliance shall be operated with combustion rate controls fully open.
•  Low burn rate: The appliance shall be operated with all combustion rate controls adjusted to the minimum setting.
• Medium burn rate: The appliance shall be operated with the register in the middle of its position.

Lacunza recommends doing medium burn cycles.

Removing ash
Following sustained use of the appliance, it is necessary to remove the ash from the firebox. Remove the ashpit box when cold or using something to prevent yourself from getting burned (glove).
Never throw hot embers into the rubbish.
Access the ashpit by opening the door on the appliance.

Deflectors.
The appliance has 1 vermiculite deflector and 2 stainless-steel reinforcement.

Removing the Nickel deflector Follow the next steps:
First, remove the 2 separators.

MAINTENANCE AND IMPORTANT ADVICE

Maintenance of the appliance
The appliance, the flue connector piping and the flue must be cleaned regularly, particularly following long periods without use.

Firebox
Clean the firebox area of ash, etc.

Inside the appliance
The inside of the firebox can also be accessed from the bottom by extracting- pushing up the cast-iron grille and removing the refractories and the ashpit. Clean the area of ash through the hollow left after removal (use a vacuum cleaner if necessary).
Clean the firebox area of ash. Clean the deflector, where soot may build up.

Flue socket
The flue socket area must always be kept clean for the appliance to work properly. It must be cleaned as often as required. How often it is cleaned depends on how much the appliance is used and the type of fuel employed.

Painted sheet-steel-cast-iron parts.
These parts should be cleaned with a brush or dry cloth. Do not dampen the parts: the steel could rust and the paint could blister and chip. Be particularly careful when cleaning the glass: the liquids used must not dampen the painted steel.

Firebox glass
To keep the glass as clean as possible for as long as possible, the secondary air register should be kept open. However, over the hours of use, the glass may become dirty. To clean it, we will use specific degreasing products or dry cleaning products for this task.
The cleaning should be carried out with the glass cold and taking care not to apply the glass cleaner directly on the glass as, if it comes into contact with the door’s closing cord, it may deteriorate. Put the cleaning product on the cloth.
Caution, the vitro ceramic glass is prepared to support 700ºC. Never let burning woods or combustion flame beating against the glass for prolonged periods of time. In this case, the glass would be submit to temperatures above 750ºC, this could change the internal structure of the glass and make it opaque (irreversible phenomenon).
Attention, never let the product drip into the lower part of the glass. The accumulation of the cleaning product, with soot or ash residues, can damage the screen printing on the glass.

Note: If we use the appliance in draught conditions higher than 15Pa or burn more wood (per hour) than those indicated in table 1.1, we will subject the appliance to working conditions higher than those designed for it. This can lead to aggressive fouling of the glass (white halo), which cannot be cleaned by the traditional method.

Air intake registers
In the air intake for combustion registers, remains of ash, sawdust, cleaning fluids, etc. may accumulate, which restrict or hinder its movement. In these cases, they should be released and cleaned.

Maintenance of the chimneyflue
VERY IMPORTANT: In order to avoid incidents (chimney fires, etc.), it is necessary to perform maintenance and cleaning operations on a regular basis; if the appliance is used often, then the chimney and the flue connector piping must be swept several times a year.
In the event of fire in the chimney, close the flue draught, close doors and windows, remove embers from the firebox, block the connection hole with damp cloths and call the fire brigade.

Important advice
Lacunza recommends that only Lacunza-authorised replacement parts be used.
Lacunza accepts no liability for any modification to the product which it has not authorised.
This appliance is a heat-producing appliance and contact may lead to burns.

This appliance may remain HOT for a period of time after it has gone out. MAKE SURE THAT SMALL CHILDREN DO NOT GO NEAR IT.
