1. Introduction
First of all we would like to congratulate you on purchasing your ADF appliance.
The result of a constant search for innovation and quality, these appliances are designed and
constructed in accordance with both current Portuguese and European legislation,
guaranteeing excellent heating performance in the homes where they are installed.
So that you can enjoy the full benefits of the appliance you have just purchased, this manual
will provide all the information you need for its correct installation and use.
Wood –An ecological form of energy
As a totally renewable resource, wood is the most ecological and economical way of producing
heat in your home. The quantity of CO2 released during the combustion of wood is no higher
than what would be released from its natural decomposition, which has occurred over millions
of years on the planet. The carbon dioxide released in its burning and that which is absorbed
during its useful life balances itself out, which means it does not contribute to the green house
warming effect of the planet. Wood ash is a fertiliser that is rich in minerals and easily
absorbed into the atmosphere in a totally ecological way.

Wood –Utilization
Seleçtion
Not all wood has the same heating power. In general, opt for hardwoods such as oak, beech
or fruit trees, the wood of which produces beautiful flames and embers that remain glowing for
a long time. Don’t use logs that are too big.
Drying
whatever wood you choose it must be completely dry: damp or green wood doesn’t heat as
well, since a large part of the energy is consumed in the evaporation of the water it contains.
Besides this, damp wood produces a large amount of smoke and a poor flame, which creates
soot inside the stove, on the glass and in the chimney. Wood should be covered or sheltered
from the rain, but well ventilated. Generally the wood should have a drying period of two
years.
Avoid Using
Resinous woods: These woods release a lot of heat but burn quickly and produce embers and
resin which dirty the chimney and the interior of the stove.
Never use
Wood which has varnish, paint, cement and glues. These can release toxic gases, besides
damaging the stove.
All ADF appliances are designed to burn wood, and only wood that is dry with less than 20%
humidity. Damp wood or other types of fuel that are not recommended will lead to loss of
guarantee.

5
Heat Propagation
There are three forms of heat transmission in a Biomass appliance. However it is through
radiation that your appliance will gain the greatest benefits.
Your stove will naturally cause air movements which are sucked into the lower part and
released through the upper part of the stove. This phenomena is called natural convection .
You may also choose to install a fan in the base of the stove in order to obtain forced
convection so as to increase the speed at which hot air is expelled and the distance that it
reaches.
The fan is thermally controlled by a thermostat that is calibrated for 50 ° C, So the venting
begins when this temperature is reached and rests when temperature drops below this value.

Warnings
A wood-burning stove is, by nature, an appliance which operates at high
temperatures. This means paying attention to potential situations of risk and
making sure they are avoided. With this in mind, please pay particular attention
to children whose natural curiosity may put them at risk and, therefore, should
be kept well away from any heating appliance.
The appliance you have just purchased must be installed by a professional to ensure it’s proper
and safe functioning. Remember that all current safety regulations must be complied with. The
appliance must be installed in such a way as to make maintenance easy. The incorrect
installation of the appliance could cause serious damage to the appliance and put people and
property at risk.
Before installing your appliance make sure that:
The floor is not inflammable;
The floor has adequate resistance capacity;
The room where the appliance is to be installed is well ventilated;
Safety distances from combustible materials are respected as mentioned in this
manual.
Your appliance must be installed in a non-permanent way making access to it easy,
to ensure the general maintenance of both the appliance and chimney.
The appliance must in no circumstances be cemented into its location.

9
Important Recomendations
It is recommended that you engage your installation by a qualified and
accredited professional.
Be careful, the outside of the stove is hot. Use suitable protective gloves
whenever you need to touch any of the hot parts of the appliance or to load
the wood while it is working.
Don’t use your appliance as an incinerator. Burning domestic waste could
cause the release of toxic fumes and cause the early corrosion of the
components of your appliance and the loss of guarantee.
The appliance is not a toy! Keep children away from it.
Check that the flue system is properly sized, ensuring a good run and that
meets European standards, so that no undue flue outlet to the surroundings
occurs.
Keep any possible inflammable materials at a safe distance from the
appliance (minimum 1.5 metres).
NEVER use combustible liquids.
The first time you use your stove you may notice a slight odour from the
curing of the paint. Avoid inhaling it and ventilate the surrounding space
well.
In the case of adverse weather conditions that disrupt the circulation of
smoke is advisable not to utlização equipment.

10
4-Installation
All local regulations, including those that reference to national or
European standards must be adhered to when installing the
apparatus.
The Chimney
You will only get the maximum efficiency from your appliance if the chimney is also efficient.
Before installing your ADF appliance check that the chimney is clean and unobstructed. If you
have any difficulties ask a professional to examine the chimney.
Both the height of the chimney, as well as breaks in
pressure in the chimneys are directly related to your
drawing, so the line must have the most straight as
possible, or failing which trajectory never suffer higher
angular deviation at 45 º to the vertical. It is also ideal that
the construction of the conduct of the flue passes through
the interior of the building thus ensuring better insulation,
and so avoid unwanted condensation originated by
temperature differentials, which sooner or later may
damage the system. (Not suitable are the flue ducts from
the outside and without insulation).
The chimneys must have individual outputs flues, and is
totally inadvisable grouping several chimneys in collective
behaviors. The outlet smoke pipes must have constant
section from the output of the stove to exhaust venting to
the atmosphere. Recommended for the exits for fumes of
fireplaces dimensions are defined in the Technical data
table.
The hat of the chimney must not possess an obstructive
manner towards the currents of outer air, ie it must allow air
to enter through the side exit can access the opposite side
causing no air currents descendants.

11
Encasing the fireplace
The appliance must be installed in areas that have adequate bearing capacity and are
composed of non-combustible materials. If the area where the equipment will be installed no
longer fulfills this requirement, appropriate measures should be taken (for example, a plate
load distribution). Flame-resistant material should be placed high temperatures across the back
of the stove, with a minimum thickness of 20 cm.
It should be noted that the stove should never be physically restrained in any direction once
should insure themselves the phenomena of thermal expansion that the materials will be
subjected. It is considered prudent that the clearance for expansion is approximately 5 mm to
each side of the fireplace.
Should never obstruct the vents! It is also desirable that in homes with good insulation and /
or possessing contiguous spaces with exhaustion, is placed a grill vent connected to the
outside of the house with about 100 cm2. Thus supplies the surrounding space with a good
supply of oxygen in order not to exhaust, and air masses moving in the right direction. As for
the air intake grilles must be taken into account that must be positioned so as not to be easy
clogging. When simultaneous with other heating appliances operating shall ensure the
existence of sufficient oxygen.

distribution
* When using the output distribution of convection (6) pg.4 before installing the equipment
remove the screw (see picture above), to release the adjuster convection.
In case of not using the output distribution of convection never remove this screw

12
Tubing
You will only get the maximum efficiency from your appliance if the chimney is also efficient.
Before installing your ADF appliance check that the chimney is clean and unobstructed. If you
have any difficulties ask a professional to examine the chimney.
Since both the height of the chimney and any breaks in pressure in the chimney are directly
linked to its draft, the conduits should have the straightest trajectory possible or where that is
impossible, the angle shouldn’t exceed 45º
Ideally, the flue conduit is constructed to pass up the inside of the building ensuring a better
insulation and avoiding any unwanted condensation originating from differences in
temperature that sooner or later could damage the system. The tubing should be preferably in
stainless steel and thermally insulated along its whole length in order to avoid condensation
specially in cold climates.
Chimneys should have a single flue and
the grouping of several chimneys into a
shared flue is not advised.
The flue conduit for conveying the smoke must
be unbroken from leaving the appliance to the
evacuation of smoke into the atmosphere.
The form of the chimney cap must not obstruct currents of air from
the outside. In other words it must allow the air to enter through one side and leave through
the opposite side so as not to cause descending currents of air.
The sizes recommended for flues for the appliance can be found on page 7 of this manual. As
you can see, the correct installation of the chimney is a crucial aspect for obtaining the best
possible performance from your appliance and, given its technical nature, it is subject to
different regulations which should be taken into account and complied with.

13
The need to gain access for the maintenance of the tubing must
be taken into account, therefore the fixing of the tubing should
not be permanent.
The chimney must be at least 0.6m from the highest part of the
roof. In any other area which is not the highest point, it should
be at least 1 m above the roof. Your chimney should be cleaned
at least once a season.

whole perimeter. It is recommended that at least one of the four hot air outlets of the
appliance is connected.
The grills for the entrance of air must be positioned so they are not obstructed.
When installing the appliance all local regulations must be complied with, including
those relating to national and European norms

6- Using the equipment
Ignition
LIGHTING ( FROM COLD)
1. When using this appliance for the first time, or after a prolonged break, it is extremely
important to carefully examine the chimney and check that it is clean and unobstructed. If
you have any problems ask a professional to carry out an inspection.
2. The appliance was designed to function intermittently, with intervals for loading wood of
between 45 to 60 min.
3. Completely open the air combustion control. At the bottom of the stove place a product
that burns easily (firelighters, pine needles, pine cones or other).
4. On the top of this, place small logs stacked horizontally (around 1Kg).
5. Leave the door slightly open with a gap of 2cm. This will allow air to get in and help the fire
get started more quickly and efficiently. Keep the air combustion control completely open.
6. After 5 to 10 minutes close the door reduce the amount of air coming in through the air
combustion control.
7. Let the fire burn until it creates the first embers.
Note: Thin and dry pieces of wood should be used for lighting.
Normal Procedure –After lighting
1. Open the door slowly, spread the embers equally over the base of the stove
2. Place logs of approximately 1kg each, horizontally. Don’t overload the appliance
and check the recommended maximum load for your model on the chart for
appliance characteristics 7.
3. Close the door
4. Choose a position on the air combustion control to achieve a regular lasting burn,
avoid an excessive burn.
Note:
 You should only reload the stove when the previous load has been completely
consumed. Don’t overload your stove ;
The paint coating the stove was not subjected to cooking in an oven, so it will
harden with the first time used. Also why on first use, emission of fumes and odors
may occur. Avoid inhalation and ventilate the surrounding space.

19
Warning: the appliance was not designed to work with the door open. Do not
open the door of your appliance suddenly, this could overpressure the combustion
chamber causing smoke or even flames to be released into the room.
Warning: if you notice any adverse atmospheric conditions which affect the draw
of the smoke it is advisable not to use the appliance.
Warning: for well insulated homes or those with forced air ventilation in the
kitchen or bathroom, it is advisable to place a ventilation grill on an outer wall
near the appliance. This safety mechanism is important to avoid oxygen in the
room from running out and from avoiding smoke from the chimney. The area of
the fresh air grill should be at least 100 cm2 and should always be kept unblocked
7-Maintenance and Cleaning
Your appliance can function for various years without any major
maintenance operations. However, you can increase its operating life and
considerably diminish the risks if you follow these principles of Cleaning
and Maintenance.
Cleaning and maintenance operations should always be carried out when the
appliance is cold.
Cleaning
empty the ash drawer often, thus preventing contact with the ash grate, your cause
warping bearing in mind that, these may remain hot enough until hours after flame
extinction.
If sooting appears on the glass it can normally be removed by using a product
specifically for cleaning glass. If the darkening persists, ask ADF or one of our agents
for a cleaning product specifically to remove carbon residues.

20
Maitenance
When the cold season ends, a time when your appliance can rest for some time,
carry out a comprehensive cleaning of ashes and any residue inside the stove
without using any abrasive products.
With the help of an ash vacuum cleaner, vacuum the burning chamber.
Clean the fan chamber and the fans. This operation should be carried out by a
qualified professional.
Over time you may think that your appliance needs painting. In this case, paint the
appliance using a high-temperature spray paint provided by ADF. You should only
paint the appliance when it is completely cold. Before painting, carefully cover any
nearby areas that you don’t want to paint (glass and hearth) and follow the
instructions on the paint can.
Clean the chimney and the neck of the chimney (remove flame deflector) at least
once a year. If necessary ask a qualified professional to do the job.
Periodically check, and replace where necessary, the sealing cord around the door.
Only use replacement pieces recommended by ADF.
Fires
This ADF appliance was designed in accordance with existing legislation so as to minimise
eventual risks of a fire in the chimney. However, should this occur:
1. Remain calm and check that conditions are safe enough for you to close down the
appliance.
2. Completely close the door of the stove.
3. Completely close the admission of air and the flue.
4. The appliance should then go out by itself due to lack of oxygen.
5. If the area is unsafe, then move away from the danger and immediately call the fire
services for help using the European emergency number.
6. Before using the appliance again, ask a qualified professional to carry out an
inspection of the chimney.
