1. ARTE®FIREPLACE -AGREEK QUALITY PRODUCT
Thank you for buying an ARTE®fireplace - we believe that you will have as much pleasure from our product as we have.
Your ARTE®fireplace is made in such a way, to extract the maximum possible energy from the wood with the minimum possible emissions,
using the most innovative technology and the most robust design - made in Greece!
These instructions contain interesting and informative facts and all you need to know about the subjects of heating, wood, and operating
your ARTE®fireplace. Please read these instructions carefully before using your fireplace for the first time and keep them in a safe place.
2. FACTS ABOUT WOOD AND THE ENVIRONMENT
2.1. Why use wood?
With proper forest management, burning wood does not deplete the earth’s resources. Heating with wood usually does not contribute to
global warming. The young trees that replace the trees in your fireplace absorb carbon dioxide from the air. Burning firewood releases only as
much CO2 as the tree has absorbed from the atmosphere during its growth. Wood rotting in the forest generates the same amount of CO2 as
the same wood burning.
Besides being environmentally friendly, the heat from a fireplace warms you like the warming rays of the sun during the sunny winter days. It is
the radiated heat that transmitted by electromagnetic waves in the infrared range. Even when the air is very cold you can feel the warm rays
of the sun on your skin.
Another advantage to wood is that it is produced locally, which creates local employment, and more tax revenues stay in the province.
2.2. Buying firewood
Where can I get my firewood?
Regenerated ready-to-burn firewood can be purchased from dealers:
Fireplace ready, stored for at least two years
Pre-dried, stored for one year
Fresh from the forest
Whether you have cut your own wood or bought it, the important thing is: the wood should be dried for at least two years before it is burned.
2.3. Storing your wood
The full potential for heat will not be realized if you neglect the
simple chore of piling and protecting your wood. Proper storage
is essential to avoid moisture, bacteria, and insect problems in
your home.
To avoid problems with insects and moisture, store the wood as
far from your house as is practical. Do not store wood in your
basement; one cord of wood can give off more than 500 liters of
water. The basic rule is to hide the wood from water, but not from
the sun or wind (Pic. 2.3.1 & 2.3.2) Green wood will dry slowly or
not at all if unprotected, while seasoned wood left unprotected
may become unseasoned.
There are three basic rules to follow when storing wood:
Allow air circulation by piling one tier wide if possible
Protect wood from rain and snow by covering with a tarp or woodshed roof.
The ideal residual moisture is 12 - 15% and should be no higher!
The manuals which are enclosed with the product must be
kept throughout the product’s entire service life.
Pic. 2.3.1 Pic. 2.3.2

INSTALLATION &USERS MANUAL FIREPLACE | NEAT 70/80/90

Pile wood off the ground on scrap lumber or wooden pallets.
The time-honored way to cure wood is to buck, split, and stack wood off the ground for one full year. How-ever, wood can generally be
reduced to 20 per cent moisture content in two to three months. The ideal 10% to 15% may take longer (almost 18 months).
2.4. Wood types and calorific value
A wood’s efficiency does not depend only on its type, but also on its humidity, as well as the temperature of the combustion chamber.
For more efficient and longer burning, without emission of hazardous substances, woods must be dry. Ideally, their humidity percentage must
not exceed 10% to 15%.
If this percentage is over 20%, the wood is not burned properly, whereas if the piece of wood has been cut recently, the humidity is over 60%
making it unsuitable for burning. The reason for that is that the fire will be weak and pale and will produce dense smoke, unburned tar and
creosote, soiling the ceramic glass and the flu.
It is preferable to get your wood supplies during the summer months and store them, to ensure better combustion quality during the winter.
Useful tips
Always choose dry firewood.
Avoid wood that pops (chestnut, conifers such as cedar, spruce and pine), as they may damage your fireplace or the flue.
Pay attention to the size of the logs. Good firewood must have been cut at least twice.
You should prefer oak, beech, olive wood, which is hard wood with high density since they will burn for longer.
Briquettes
They ignite very easily, and burn slowly. They are economically advantageous because you will burn smaller quantities compared to common
firewood and they are easily stored. Also, you have less quantity of ashes vs. to wood.

Birch
It’s a soft wood that ignites easily with great thermal energy production. It
produces less smoke and ash compared to other wood and burns silently. The
same characteristics apply for lime and chestnut.
Beech
Hard wood is ideal for firewood but requires a high temperature to ignite. It
weights a lot; it is dense and burns with a calm and long fire for a longer time.
Best when well seasoned. The same applies for oak, but seasoned for 2-3
years.
The various wood types have various calorific values

Briquette 5.000
Birch 4.800
Walnut 4.731

Olive 4.100
Poplar

Table 2.4.1
860Kcal/h = 1 kW/h
The values are based on 15% residual wood moisture.
2.5. Determining the heat output
There is not a specific rule that enables the calculation of the required heat output. This depends on the amount of space that is required to
be heated and mostly on its insulation. In average the required heat output for a properly insulated room and with external temperature of 0ο
is 40 kCal/h per m3.
Taking into account that 1kW equals 860 kCal/h an equivalent of 50W/m3can be used. For example, to heat a 50 m3room (10 x 6 x 2.5m) in
an insulated residence, the output required is 150m3x 50W/m3= 7500W or 7.5 kW.
So for the main heating, a 10kW appliance is enough.

must be at least 35 cm (Pic. 6.1.1).
For non flammable material, no requirements apply.
6.2. Wooden beams protection
Given its properties, heat is transmitted through radiation. In case there are any wooden beams inside the radiation zone or in the way of the
hot air, they MUST be properly insulated because the continuous exposure in high temperatures can make them deteriorate faster or even
cause self ignition. Use proper insulation materials that are in accordance with European rules or, in case of high thermal stress you can also
use metal linings.
6.3. General security instructions
Never leave children alone or without supervision near the fireplace when it is lit.
Teach children how to operate the fireplace correctly and safely.
Never touch the external surfaces of the fireplace or the glass when it is lit. There is a high risk of burns!
Due to the self closing door, you have to be extra careful when you are filling the fireplace.
It is forbidden to use the fireplace as a waste incinerator.
Don’t use burned or used wood as fuel.
Remove the ash only after it has completely cooled off.
Ash should be placed outdoors or be disposed in a place where there is no risk of ignition.
Immediately inform your specialized local supplier if you find any malfunction.
Don’t use chemicals or liquids as fire starters.
Do not use ANY fuel other than the recommended
6.4. Flue security instructions
Prior to installing the ARTE® fireplace the chimney sweep or a qualified technician should check the condition and operation of your chimney
in accordance with the standards EN13384-1 & EN13384-2.
This way you ensure the best conditions for heating without issues.
6.4.1. Basic requirements for proper flue operation
The internal section of the flue must preferably be circular. In a case of square or rectangular
flue, the internal corners should have a radius of at least 20mm. In case of rectangular flue, the
ratio of the sides should be at maximum 1: 1.5
The flue must be properly insulated and waterproof and constructed of materials with thermal
resistance and resistance to combustion products and any deposits.
The flue must have no constrictions; it must have a vertical path and it should not change in
direction that exceeds 45o. (Pic. 6.4.1.1)
In case of an existing flue the construction material should be checked. Materials such as
cement with lime, galvanized steel and rough or porous materials are contraindicated as they
Pic. 6.1.1 Pic. 6.1.2
Follow the operating instructions supplied with the product to help prevent fire and
protect the environment.
Pic. 6.4.1.1

INSTALLATION &USERS MANUAL FIREPLACE | NEAT 70/80/90

create issues in the correct operation of the fireplace. Also, a proper study for the flue size must be conducted because often old flues have
quite large diameters. This means that the amount of air draft is not proportional to the heat generated by the fireplace and by extension
means that you consume more wood than necessary and will spend more time on maintenance. The solution proposed in these cases is the
connection of an inner tube inside the flue. This tube should extend over the whole length of the flue and at no point should exceed in
diameter the outlet flue of the fireplace. If the existing flue has the desired diameter a proper cleaning by qualified personnel should be
done.
Inserting the pipe along the outer wall must be properly studied to avoid heat loss. This solution, however, is contraindicated, as positioning
the flue inside the house warms more spaces as heat of the flue remains in the house.
6.4.2. Chimney placement
The placement of the chimney on the roof is a particularly decisive factor in the convection of the fireplace.
An incorrectly fitted chimney may generate reimbursement of exhaust into the heating space due to down flow of the air.
Follow the instructions below to ensure proper dissipation of smoke. (Pic. 6.4.2.1)
The ending of the chimney must be at least 50cm above the top of the roof.
If there is more than one chimney on the roof, they must be positioned at least 2m apart.
If there are two adjacent chimneys, their ends must be at least 50cm apart.
If there is a tall building or tree next to the house, then you should place the chimney at a distance greater than 5m from the obstacle.
It is prohibited to connect several devices to the same chimney. Every chimney should be autonomous. (Pic. 6.4.2.2)
In case of an inclined roof, the height of the chimney is defined depending on the inclination and the distance of the chimney from the
ridge according to the following table. (Pic. 6.4.2.3)

6.4.3. Chimney cap
The chimney draft depends broadly on the adequacy of the cap.
Pic. 6.4.2.1

So, in case the chimney is built, its exhaust diameter should be at least twice the inside diameter of the chimney. Knowing that it is necessary
to protrude from the ridge of the roof, the cap must ensure the proper smoke dissipation in case of strong wind.
A chimney cap must meet the following requirements:
Internal diameter must be equal to the diameter of the chimney.
Exhaust diameter be at least twice the inside diameter of the chimney.
It should be constructed in such a way as to avoid the entrance of rain, snow and any foreign body in the chimney
It can be checked, maintained and cleaned easily.
6.5. Malfunction - Secure fireplace shutdown
In rare occasions even a test fire may not cause sufficient draft in the flue. In this case contact your chimney sweep. Under no circumstances
should you try to light a larger fire. If smoke escapes from the fireplace, ventilate the room immediately and contact your chimney sweep.
DON’T LIGHT THE FIREPLACE!
7. INSTALLATION
7.1. General information for installation
It is necessary that the flue gas tube is connected to a certified conduit with the same diameter as the fireplace, by
following the dimensions of the adjacent image (Pic. 7.1.1). For NEAT fireplaces the minimum diameter of the flue is
150mm if it is steel made or 180mm if it is made with concrete, ceramic or brick. The flue must be properly insulated
with stone wool with thickness of at least 4cm with external aluminum foil. Do not use fiberglass or paper based
insulation. Also, do not use flexible thin walled metallic tubes or asbestos tubes. The tube should be perfectly sealed
and well insulated throughout its length.
7.2. Installation in existing fireplace
Before installing the fireplace you must ensure that the minimum height of the installation space is 490mm and the opening is at least
695/795/895mm, according to the type of the device.
To install an ARTE® NEAT fireplace in an existing fireplace is necessary to remove the main unit from the metallic shell, as other metal parts
also. The following steps explain this procedure.
Make sure that the floor can withstand the weight of the device. If the existing
construction cannot withstand the weight of the device, a load distributing plate is
necessary.
Also, make sure you provide proper insulation in case the floor is built using flammable
materials.

18. Ensure that the washer is in on the hinge. Place the door and and clip the retaining ring. (Pic. 7.2.20)
Before installing a NEAT fireplace you must close the inner part of the flue with a deflector with an
appropriately drilled plate or other refractory material that can withstand high temperatures
without damage.
The space extending around and over the device up to the deflector must be ventilated
continuously. For this reason you must allow cool air from a lower spot, for example, the bottom and
the outlet of the hot air from above. (Pic. 7.2.21)
These openings must remain free and not able to be covered. The must also have a minimum
surface of 300cm2, for example, a grille with size 30x10cm.
This way you achieve:
greater security
Increase on the heat of the room, due to the air circulating around the device.
The hot air extract grille must be placed on top of the trunk approximately 20cm from the ceiling.
The grille must always be installed, as its purpose is to allow, the heat that builds up inside the trunk
to be released in the room and also to relieve the pressure created.
7.3. Installation on a ARTE base
ARTE® gives you the option to install NEAT fireplace on a compatible base (Pic. 7.3.1) (optional equipment). In
this case you can align the device by leveling the ARTE base legs. So the disassembly of the main unit from the
metallic shell is not necessary.

7.4. Air supply to adjacent rooms (Channel set-Optional Equipment)
ARTE® NEAT fireplaces have an option for connecting air tubes and provide hot air in adjacent rooms. At the top of the device there are two
holes in which you can connect said conductors.
To install the conductors you must follow the procedure below:
1. Configure appropriately the adjacent walls or drywall to install air ducts, with maximum diameter of 150mm, which must be properly
insulated.
2. Remove the holes covers by using a hammer. (Pic. 7.4.1)
3. Install collars with a diameter of 150mm (optional equipment) on the holes and bend the mounting strips. (Pic. 7.4.2)
4. Mount the air ducts to the collars by using clamps. (Pic. 7.4.3)
Pic. 7.4.1 Pic. 7.4.2 Pic. 7.4.3
The air ducts must be properly insulated to avoid noise and heat loss.
The output of the air ducts must be at least 2m above the floor so that the hot air is not directed straight on humans.
In case tubes over 5m are used, you must also install ventilators on the end of the tube in order to propel the air ducts that provide hot air on
adjacent rooms.
7.5. Combustion air intake
ARTE® NEAT fireplaces provide two different options for combustion air intake.
1. Use of internal air:
To use internal air remove the covers from the front of the device. (Pic. 7.5.1)
The presence of kitchen hoods, ventilation systems or other heating appliances may affect the operation of the fireplace. When operating
Opening the holes for the combustion air intake is IMPORTANT!
In case it is not done, there is serious risk of destroying the fireplace.

more than one device, make sure that there is sufficient air intake. The simultaneous operation of a kitchen hood or a ventilation system
with the fireplace may draw in hazardous gases from the fireplace towards the interior of the room.
According to the operating regulations, the concomitant use of similar devices may be
acceptable only if there is a flue gas control device. When there is a kitchen hood, a ventilation
system or other heating appliances in use, at least one window in the room must remain open.
2. Use of external air:
To use external air remove the bottom or the rear cover depending on the place you want to adjust the air inlet (Pic. 7.5.2) & (Pic.7.5.3)
Although the fireplace uses external air for combustion, make sure that the room is ventilated adequately when the fireplace operates
with external fresh air. When you open the door of the combustion chamber for adding firewood there should be no pressure difference
between outdoor and indoor air in the room, so it is good to keep the door open for about 1.5cm for 5-6 seconds and then fully open it.
ARTE® NEAT fireplaces allow fresh air from two different inlets:

8.3. General information
8.3.1. When the fireplace paint dries
ARTE ® products are painted in spray booth with as more environmentally friendly and ecological colors as possible. There is although a
possibility that the first few times the fireplace is lighted, the paint emits an odor. Let the fire burn with intense convection until all traces of
gas disappear and there is no longer a smell. The gas is not toxic, but the room should be well ventilated.
8.3.2. Incineration preparation
Prepare sufficient amount of chopped firewood, kindling and branches or torches. Before using the wood it is recommended to store them
in a warm place for a few days.
8.3.3. Heating during seasonal change or in adverse weather conditions
When there is high humidity or fog, with temperatures ≥15 ° C, but also during the transitional period between seasons, it is recommended
to light a test fire before normally lighting the fireplace. This will displace the cold, heavy air that is inside the flue and create the right
conditions for optimum smoke dissipation.
9. LIGHTING THE FIREPLACE
9.1. Traditional method of lighting
Every time you light the fireplace, it initially requires large volumes of air. When the fireplace is cold, leave the door slightly open for the first
few minutes and turn the combustion air regulator (Table 8.2.1, line 3) on position 8.
To form an adequate layer of ash at the base of the fireplace, use 1-2 kg of dry kindling the first time you light it. If it is possible, constantly
maintain a layer of ash with thickness of 2-3 cm at the base of the combustion chamber for added insulation.
1. Place 2-4 kindling tablets or 7-10 wrapped newspaper sheets beneath 1-2 kg dry kindling.
2. Turn the combustion air regulator (Table 8.2.1, line 3) on position 8.
3. After the the ignition of the tablets/wrapped sheets, leave the door slightly open in order to ensure an adequate convection of the flue.
4. Once you ensure the flue is warm enough (after 5-10 minutes), close the door. If all required conditions are met, after 15-20 minutes a thick
layer of cinder will be formed in the combustion chamber and the temperature will rise, which is essential for the continuation of
combustion.
5. Once the requirement described in point 4 is met, place 2-3 logs with overall weight of 1-3 kg, depending on the size of the fireplace, on
the cinder, with a distance of about 1cm from one another.
6. Open the air supply to the maximum level and close the door. The wood will begin to burn within 2-3 minutes. If not, open the door slightly
in order for enough air for combustion to enter. Close the door again once the wood ignites.
7. Lower the combustion air regulator (Table 8.2.1, line 3) between positions 1 to 4, so that the combustion continues seamleassly and ensure
there is adequate air supply (oxygen) to maintain the flame clear and powerful when you reduce the amount of combustion air and after.
8. As soon as the fire leaves a thick layer of cinder, you can add more firewood by repeating steps 5-7, every 45-55 minutes according to the
type of the device.
9.2. Lighting without CO emissions (FROM TOP TO BOTTOM)
1. Turn the combustion air regulator (Table 8.2.1, line 3) on position 8. If needed, leave the door slightly open in order to ensure an adequate
convection of the flue.
NEVER USE THE DEVICE WITH MAIN DOOR OPEN BECAUSE
YOU RUN THE RISK OF DESTROING THE DEVICE!!!
To avoid covering the glass with soot, it is
important not to let logs lean against it.
Don’t leave the fireplace unattended as long as the door remains open.
Due to the self-closing door you should be very careful for
any accidents during the fueling of the fireplace.

2. Place 2-3 logs with overall weight of 1-3 kg and 30-60cm, depending on the size of the fireplace.
3. Place 2-3 kindling tablets or 5-8 wrapped newspaper sheets between the logs.
4. Add a few twigs (1-2 kg) on the top in zigzag arrangement.
5. Finally, place a medium log on top of the stack and light the tablets/wrapped sheets.
6. Once you ensure the flue is warm enough (after 5-10 minutes), close the door.
7. Lower the combustion air regulator (Table 8.2.1, line 3) between positions 1 to 4, so that the combustion continues seamleassly and ensure
there is adequate air supply (oxygen) to maintain the flame clear and powerful when you reduce the amount of combustion air and after.
8. As soon as the fire leaves a thick layer of cinder, you can add more firewood, every 45-55 minutes according to the type of the device.
Feed the fireplace often but with small amounts of firewood, at most 1-3 kg, depending on the size of the fireplace, each time. If the fireplace
is overly full, the generated heat may cause excessive strain on the flue. The supply of firewood should be done in moderation.
Wood combustion rules
If you want less heat, put a smaller quantity of wood in the fireplace and reduce the amount of air. It is however important to maintain
an adequate layer of cinder.
Less heat = Less wood = Less air.
More heat = More wood = More air.
When the fireplace operates at excessively low power or if the wood is not sufficiently dry, soot might deposit on the glass.
10. PRIMARY AND SECONDARY COMBUSTION
The combustion of wood requires a process of primary and secondary combustion to be efficient.
1. Primary combustion
Primary combustion is the initial wood burning at relatively low temperatures. During the primary combustion, large amounts of soot, creosote
and gas are produced due to the existence of water in the wood. Creosote, in primary combustion, contains 60% of the potential energy of
wood, but it is deposited in the form of soot inside the fireplace and the flue without imparting any heating.
2. Secondary combustion
The combustion chamber is insulated so as to increase the temperature of the core and by
providing just the right amount of oxygen necessary to 600OC, the creosote ignites spontaneously.
This creates a chain reaction that increases the temperature inside the fireplace from 600OC to
about 870OC without having to add any more fuel. This is the secondary combustion.
Thereby, the more proper secondary combustion is achieved the higher temperatures are
produced and the less residue is left (gas and particles). The vast majority of secondary combustion
is only done in the upper part of the chamber near the outlet of the flue. Thus a large part of the
heat that is achieved, is discharged directly through the draft of the flue to the exterior and not in
the heating area.
ARTE’s® chamber manages to provide the maximum secondary combustion performance. The
The openings of the secondary air supply
should not be covered by firewood.
The fire should be vigorous and the smoke exiting
from the flue must be almost unnoticeable.
The fire should not be smoldering because it is causing more pollution.
If the door remains slightly open, fire gases and flames may
escape from the opening of the fireplace causing a risk of fire
or asphyxiation. We recommend installing a smoke detector in
the room where the fireplace is located.
DO NOT OVERHEAT THE FIREPLACE! There is risk of fire or permanent damage.
If any part of the fireplace starts glowing, then the device is overheating.

combustion chamber’s design including air intakes to the rear side and air curtain on the ceramic crystal , succeeds perfect air circulation in
such a way that on any single section of the chamber the sufficient amount of preheated oxygen is provided. This way the whole area of the
chamber is converted in a secondary combustion chamber, not only the upper part, and thus its performance dramatically increasies and
inversely gas residue reduces.
11. CLEANING &MAINTAINING THE FIREPLACE
11.1. External maintenance
The fireplace surface is painted with heat-resistant paint. It is best kept clean by vacuuming with a soft brush attachment or by wiping with a
lint-free cloth. Over a period of time, the painted surface may become slightly grey. A canister of touch-up ARTE®spray paint should be
available from your fireplace supplier. This can be applied - in accordance with the instructions - in just a few minutes. When first firing, after
touching up, the fireplace will give off a slight smell as the paint cures. Make sure to ventilate the room well during this phase.
11.2. Internal maintenance
11.2.1. Ash disposal
Empty the excess ash as often as necessary in order for the level to remain below the appropriate
(Pic. 11.2.1.1). ARTE® NEAT fireplace is designed to produce the least amount of ash, almost 1Kg
for every 100Kgs of firewood. Dispose the ash by following these steps:
Open the main door and use a small shovel or a scoop to remove the excess ash.
Dispose the ash in a metallic container with a tight lid
The closed container with the ash should be placed on a nonflammable floor or on the ground,
away from flammable materials until the final disposal of the ash. The ash must be stored in a
closed container until cooled down, or buried on the ground or dispersed somewhere.
11.2.2. Glass
If the fireplace is generally operated at the correct temperature, there should be little or no soot on the glass. If it does settle during lighting,
most will burn off as temperature increases.
For normal cleaning, moisten a paper towel with warm water and add some ash from the combustion chamber. Rub it over the glass and
then clean the glass with clean water and dry it well. For heavier deposits that cannot be cleaned, use glass cleaner, applied when the glass
is cold, in accordance with the instructions.
Never use abrasive cleaners on the glass surface.
Reasons for the presence of dirt on the glass
Firewood is too wet
Logs are too large or not split
Combustion temeratures are too low
Never empty a fireplace while in use.
Never use your household or shop vacuum
cleaner to remove ash from the fireplace.
Always remove and dispose of the ash properly.
Due to the self-closing door you should be very careful for any
accidents during the maintenance of the fireplace
When performing maintenance on the fireplace, always
protect yourself, using safety goggles and gloves
