2. FUEL
2.1. RECOMMENDED FUEL
The quality of the wood is extremely important for the optimal functioning of
the stove (output, clear glass, etc.).
Good quality wood is wood that has been dried under an aerated shelter for
at least 2 years (+ 18% moisture content). Damp wood gives off less heat
and dirties the stove and the chimney.
You can also use briquettes, and it is best to use them in combination with
wood because burning only briquettes makes the temperature too high.
Optimum fuel efficiency and optimal operation of the heater is achieved
loading of about 3.5 kg wood per hour, horizontally placed on the grate in
the middle of the combustion chamber.
Chimney draft should be 12 -15 Pa and regulator of air supply at maximum.
2.2. FORBIDDEN FUEL
The use of treated wood (painted, etc.) and all types of household
waste, which can disperse hazardous gases, is FORBIDDEN and
CANCELS OUT ANY CLAIM ON THE GUARANTEE. The use of fluid
fuel (petrol, etc.) is also forbidden.
2.3. STARTING THE FIRE
Regulator of air supply at maximum (Pic.16).
Open the lifting door (Pic.3).
Put a bed of tinder (paper or firelighters) with a little kindling (small twigs
or pieces of wood) in the stove and light the tinder.
Leave the door slightly open (+ 3 cm) to get a turbo stream of air that
will make the some kindling catch fire.
After the kindling have caught fire and burn well, the logs may be placed
on the fire. After the logs have caught fire, the door may be shut.
NOTE: When a fire is made for the first time, the paint will harden and that
give off smoke and a smell, which starts after the fire has burned for about
10 minutes and lasts for about 30 minutes. Make sure the room is ample
ventilated.
CAUTION:
It is not necessary to overload the fireplace with wood. 1 kg dry
wood gives a 4 kW power.
Example: a fireplace with an 80% return gives a power for about
4kw x 80% = +/- 3.2 kW for 1 kg dry wood.
If you want a power of 6-7 kW, it is just enough to put 2 kg wood
in the fireplace per hour. This is like one-two normal pieces of
wood.
Be careful not to use pallet wood (this gives an enormous heat) for
continuous heating. This can lead to fire hazard. We are not
responsible for the bad use of the fireplaces and any consequence
for not following this guideline.
The outer surfaces of the device are hot during operation, what
should be paid proper attention to avoid burn injury.
Pic.5
To close, push the door gently (but not to soft) against the hooks.
Make sure that all hooks are hooked.
Pic.4
Above the glass (below the upper frame) hooks are provided. Push
them upwards with your fingers. The window can be now opened at
an angle of to 45°.

3. INSTALLATION
3.1. ACTIONS TO BE TAKEN UPON INSTALLATION
Your supplier is the specialist who chooses to represent M-design in your area.
For your own safety and satisfaction, we advise you to entrust him with the
installation. The appliance has to be installed according to certain prescribed
rules and local regulations.
In the absence of the correct regulations in Belgium, the French regulations in
respect of installation will be (D.T.U. 24.2.2) applicable.
The device must be built on an area with adequate bearing capacity or slabs,
which can spread the weight of the device. The device must be placed so as to
meet all safety distance from combustible materials that could cause a fire.
However, if you decide to carry out the work on your own, we advise you to
do the following:
• Refer to the terms and conditions of our contract of guarantee.
• Ask your supplier for advice.
3.2. POSITIONING THE FIREPLACE
Foundation under the fireplace insert must be of non-combustible material, flat
and must withstand thermal stress. Also, the walls and ceiling material, with
which the finishing fireplace insert, cannot be flammable or should be used
with suitable insulation.
The floor must be guaranteed minimum load capacity 1000 kg m-2 in the
place of installation of the fireplace insert.
The floor in front of fireplace insert must be from non-combustible material at
least 100 cm in front of the front wall of the fireplace insert. The device must
be installed so that the front of it remained free space on a minimum ground
plan of about 1 x 1 m.
Place the appliance on a stable surface using the adjustable feet. Adjust the
height of the appliance turning the bolt.
THE STOVE MAY NOT BE PLACED DIRECT ON THE
FLOOR TO ALLOW NATURAL CONVECTION. THE
APPERTURES FOR THE AIR SUPPLY (IN) IS SITUATED
UNDERNEATH THE APPLIANCES.
Regulating the height of the appliance:
This can be made in two ways.
A regulation by 5 cm (Pic.6) and a fine regulation by screw (Pic.7 ).
The minimal height as from ground to the 4th side frame is 8 cm (A min).
The minimal height “C min” will be 22,6 cm, measured as from the ground to 4th
side frame.
3.3. AIR SUPPLY FOR COMBUSTION
Every form of combustion uses air. In the case of a thermally sealed room
supplementary air supply is essential. One must at all times avoid creating
under-pressure in the room. If a cooking hood appears to be absolutely
essential in the adjoining room, sufficient air supply will have to be provided
to avoid every form of under-pressure.
You need an air supply with dia. 150mm coming from outside, or a ventilated
place (garage, basement ...). This air inlet you have to connect to the Argento.
Opening for the external air supply is located at the bottom and sides of the
fireplace Argento (Pic.9). For the air supply from side is necessary to remove
the side covers.

3.4. INSTALLATION OF FIREPLACE IN THE PLACE OF USE
When the Argento is installed there is possibility to choose distribution of hot
air with ducts, where inlet temperature is 150 °C. In this case is Argento
supplied with convection chamber - premium version (Pic.10). If hot air ducts
are not in demand, hot air needs to be provided flow out of the surround. Air
circulation must be ensured. There is also possibility to place Argento to the
accumulation surrounds then you can install the device without convection
chamber (Pic.11).
Pic.10 Pic.11
4. INSULATION AND FINISHING
Please, follow this instruction. The appliance can overheat if you do
not apply these instructions.
Once installation is complete, the appliance can be fitted. Once you have
checked everything, you can perform the final insulating and finishing
operations.
The built-in part of the furnace tends to be very warm. Please check that the
furnace is not fitted too narrow and that there is adequate space for the
elimination of hot air. For insulation of the furnace, we advise you to use
M-Design insulating plates. You are advised against using any other insulation
product. Inflammable materials as well may not be used for the finishing.
The masonry must be raised around the furnace. Because of the
expansion of the furnace during combustion, an interstice of at least
5 mm must be provided on front side and 4cm on others sides of the
appliance. The masonry must not lean against the furnace.
THE APPLIANCE MUST BE SET FREE.
Please pay attention to leave approx. 2 mm inbetween the finishing
frame and masonry (mounting a 3-sided frame).
This dilatation space is used to compensate thermal expansion of
the fireplace and its individual parts when is heated and cooled.
A very essential point when setting up the Argento is that the distance has to
be respected inbetween fireplace and the finishing material for the
mantlepiece such as marble, gipsum...
It is necessary that air can move freely around the device. Air gap allows air
circulation in the surrounding appliance, through natural convection.

5. CONVECTION CURRENT
5.1. NATURAL CONVECTION AND HOT AIR DUCTS
Please follow the installation guide. The appliance can overheat if
you not apply those instructions.
It is compulsory to open hot air vents at the top of the appliance (Pic.13/1).
The entrances for the air supply convection are situated on the bottom side of
the Argento (Pic.13/2) and also through the opening that is provided for the
fan.
The device is placed at least 20 mm above the floor (if placed on the floor) to
allow for natural convection.
A clearance of at least 4 dm3, excluding the measurements of a dust filter, or
at least 6 dm3, including the measurements of a filter, must be provided for in
the masonry.
The enclosure of the appliance must be provided with ventilation grills or
openings allowing for the elimination of heat by convection. It is possible to
have a convection kit fitted with the appliance. This system directs the heat
inside the room by means of flexible tubes (dia. 150 mm).
Thermally insulated ducts are essential for the optimal functioning of the
appliance (these cause ‘draught’ in the convection air current). By using the
maximum number of ducts (at least 2), the output is improved and the noise
(that is caused by the displacement) is reduced.
For the purposes of the installation of these ducts it is best to go vertically
upwards first for at least 1m and then to change direction, making a rather
wide bend and avoid using a flue terminal grid with a small clearance
because the speed loss that this causes reduces the efficiency of the hot air
vents.
Place all the fittings that you use at the same lengths and angles if possible,
otherwise some grids could give off more heat than others and, seeing that a
hot air pipe functions in a manner similar to a chimney, the one that is hot first
has the most draught and therefore becomes hot even more quickly.
Note: A circulation of hot air requires that no under-pressure be created in the
room. A grid that is near the floor sees to it that cold air can be drawn in.
Don’t connect those with a flexible. Air will find the way to get at the right
place.
M-design has developed its ideal hot air grids which have many advantages
(Pic. next page) and for the elimination of hot air and the entry of warm air
we advise you to use these Design grills made by M-Design. To simplify the
mounting of the grids you can use the corner profile which is furnished with the
grid. This profile can be mounted on the side of the grid (two little wholes and
screws are provided).
ATTENTION: A house is never completely 100 % dustfree, heating appliances and
warmth circulation creates dust particles. During the periods where you are not using
the fireplace, dust is accumulated in the flexible pipe and the grills. This could cause a
problem with a smell, so we would certainly advise you to clear the flexible and air
inlets and outlets using a vacuum cleaner regularly. The smell caused by these dust
particles will disappear after you have used the fireplace again a few times. This
phenomenon is very common and can be compared to the gray traces appearing
above your radiators. Optionally you can order design metal lids to cover the inlets
and outlets during the summertime.
5.2. FAN
Installation:
Remove the Chamotflex plates, the bottom plates and the opening to the fan.
Now slide the fan downwards to just under the stove.
Make the necessary electrical connections.
Fan dimmer:
Leave the adjustment of the fan speed closed.
Fuse 1.5A (Take the knob off, unscrew the little plate, take it out if it is
needed to be replaced.)
The adjustment screw for the minimum speed is under the knob. (M-design has
developed a new induction dimmer which lets the fan run noiselessly and
which may be bought as an option.)
The fan (optional) may be started after the fire has burned for 15 minutes.
Let the fan turn at the maximum speed for 12 hours the first time to let it run
in.

5.3. CHIMNEY
The construction of chimney must comply with strict conditions:
The flue must be thermally insulated. The opening into the flue and its
position are very important.
One individual flue does not have more than two changes of direction. The
angle of the corner of these changes of direction may not be greater than
45 ° with the perpendicular.
The existing obstacles in the vicinity of the opening into the flue must be
taken into account.
Do not connect more than one stove to a chimney.
All the Argento stoves have a standard flue opening of 200mm or 250 mm. in
diameter. Certain chimney configurations may require different standard
diameters. In that case, look at table for the height of the flue and the
possibility of reducing the diameter with the help of a reduction piece.
Chimney connection is situated on the top of device.
When the door is closed there is slow directed flue flow to the chimney in
combustion chamber. Valve for short cut is opened and closed according door
movements. It is automatically opened when the window is slid open, so that no
smoke escapes into the living room.
Note: per 45° change of direction, one must keep to within 1m of this table.

5.4. AIR SUPPLY REGULATION
The air supply to the Argento can be regulated manually. Use the key (Pic.15)
to slide the regulator to the left to close primary and secondary air and on
the right for opening primary and secondary air. When door is open this
regulation will not have an effect on the fire.

6. GENERAL RECOMMENDATIONS
The appliance must be connected to the chimney and tested before the
material is cemented in. In order to ensure that the appliance functions
optimally do not put any inflammable materials in the immediate vicinity of
the stove. Insulating materials: it is preferable to use “high temperature”
materials. It is strongly advisable to position the chimney and to connect the
stove in such a way that no humidity or water can enter the stove. Humidity
and water are the biggest enemies of the Chamotflex in the appliance
because it can swell and burst after the fire has been lit.
Note: If you leave the door open, little burning pieces of wood may be
projected onto the floor.
6.1. MAINTENANCE
Besides regularly cleaning the window, you must have your chimney swept
at least once a year for optimal functioning of the Argento. (Not only is
this a legal requirement, but it is also meant for your own safety.).
A fire brick (Chamotte) can still work perfectly, even if it is cracked, but if
pieces are missing the brick must be replaced to effectively protect the
combustion chamber.
Remove the remainder of the ash in time, take the ash pan and remove a
great part of the ashes from the Argento. Note: Never remove all the
ashes because a fire always burns better with its own ashes.
Cleaning of labyrinth deflector:
Before 11/2015: Fold out the deflector 1 toward (soot will fell down).
This cleaning is necessary to do once a month during winter heating
season. In case if you don`t clean it the labyrinth deflector can
obstruct and it can caused bad combustion and excessive smoke.
After 11/2015: self-cleaning of labyrinth deflector by door opening.
Closed door Opened door
It is necessary to grease the convection mechanism with heat-resistant
silicone oil if you use the stove frequently. DO NOT USE ANY OTHER type
of grease or oil. This Teflon-based grease is also available from the
M-design dealers. The mechanism could otherwise dry out and the window
could be blocked when the temperature is constantly high.
6.2. CLEANING THE WINDOW
Close the window.
Open the window to 45°.
Once you have done this, you can slide it up and down to clean it.
We advise you to use M-design’s “Bio-Clean” to clean the window, which
is available from your supplier. It is one of the few products that do not
harm the lacquer.
