standards as well as the NS3058 Norwegian standard and is thereby approved for installation and use in
Europe. At the same time, the manufacturing process is subject to external quality control. DoP (Declaration
of Performance) and DoC (Declaration of Conformity) can be downloaded at www.adurofire.com/download.
Aduro H2 adheres to the following directives: EMC DIRECTIVE 2014 30 EU, LVD DIRECTIVE 2014 35 EU,
2006 42 Machinery Directive. The Wi-Fi module has been approved according to CMIIT ID: 2016DP3252. All
local regulations including those referring to national and European standards must be complied when
installing the stove.
1.2 Warnings and safety precautions
•The lid to the pellet container must always be closed during use.
•When using wood logs in periods without electrical power you must always look after the stove, as
security sensors are not active.
•The product and the cladding must be stored in a dry place and must not be exposed to weathering.
•Disconnect the product from the power supply before performing any maintenance operation.
•Improper use or poor maintenance of the product can cause hazardous situations.
•Do not place flammable materials on the stove to dry. Keep any flammable materials in safe distance
to the stove according to the manual.
•Failure to have the annual stove maintenance performed by qualified personnel, e.g. an authorized
technician, will result in the loss of the warranty. water or other liquids.
•Installation, start-up visits, tests, and maintenance must be carried out by authorized and qualified
personal.
•Do not operate the product if the glass is broken.
•Turn the product off in the event of a fault or malfunction.
•If one of the following alarms "dropshaft hot", "shaft sensor defekt" or "external auger output defect"
is activated, do not use the stove - not with firewood either - until the fault has been rectified, as this
may damage the stove. Using the stove anyway can lead to a very costly repair of the stove.
If you want to fix the error yourself, then follow this FAQ: https://aduro.microsoftcrmportals.com/en-
us/knowledgebase/article/KA-01157. If it is very important to you to get heat from the stove, even if
there is a fault in the external auger, the internal auger must be removed and the fall shaft (shaft
between the two augers) must be emptied of pellets. Remount the internal auger. The stove can now
be used with firewood until a technician can rectify the fault.
•The doors on the stove must remain closed when it is not used.
•Do not put any fuel or anything else other than wood pellets in the container. We do not recommend
a particular type of pellets, but they must be of a good quality, approved and comply with European
standards. Our experience, however, says that bright pellets burn better than dark pellets. It is
important that you only use dry pellets.
•The product must be powered by an electrical system that is equipped with an earthing stove.
•In the event of fire in the chimney, turn off the device, disconnect it from the main electricity, close
the air inlets and do not open the door and then contact authorities for help.
•This stove can be used by children aged 12 years and above. Children must not play with the stove.
Children without supervision shall not carry out cleaning and maintenance.

53
•Persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge
can use the stove if they have been given supervision or instruction concerning use of the stove in a
safe way and understand the hazards involved.
•The installation of the stove must be in accordance with legislation and regulations in the region or
state.
•Any flammable objects must be kept at a safe distance from the product due to fire hazard in
accordance to the product manual.
•Use only the fuel recommended by Aduro A/S. It is forbidden to use any liquid fuels and bioethanol
fluids for lighting/ rekindle charcoal or pellets.
•Some of the surfaces on the product can get very hot (door, handle, glass, smoke outlet pipes, etc.).
Avoid therefore direct contact with these parts, without adequate protective clothing or suitable tools,
such as gloves with thermal protection.
•Accumulated and unburned pellets in the brazier after “failed start-up” or alarms must be removed
before lighting again. Check that the cave is clean and positioned properly before lighting again.
•We recommend that you install a smoke detector in the room where the Hybrid stove is installed.
•If the smoke temperature exceeds 350 degrees, it can damage the gear motor.
•It is recommended to let the stove burn empty for pellets and clean it before a still stand period
longer than 2 weeks –especially if the humidity is high.
•A yearly service visit is obligatory and crucial to the functioning and safety of the stove. See section
6.4.
Aduro A/S declines all responsibility for any damage which may be caused, directly or indirectly, to persons,
animals, or objects as due to non-compliance with any provision specified in the manual, especially warnings

When taking your Aduro H2 home, please ensure that it travels in an upright position. The packaging must
be disposed according to national rules regarding disposal of waste.
2. Installation of the Aduro H2
You are welcome to install your Aduro H2 yourself –but we strongly recommend that you consult your
chimney sweep before you begin the installation. Your dealer can also provide you with installation advice. It
is important to ensure that all local rules and regulations, including ones relating to national and European
standards, are complied with when installing this device. Further, it is important to ensure that the fireproof
tiles and the exhaust deflector in steel is placed correctly. Remember, it is your responsibility that rules in
force are complied with.
2.1 Position of the hybrid stove/distance requirements
The new Aduro H2 must be installed in a suitable and physically possible position. You need to be sure that
the position complies with local regulations. Distance requirements will only apply if the Aduro H2 is to be
placed close to flammable materials:
You may not begin to use the Aduro H2 until it has been inspected and
approved by your local chimney sweep.

55
Distance to flammable material (see also illustration below)
Behind the stove
To the sides
Corner arrangement
To furniture
7.5 cm
40 cm
10 cm
100 cm
To secure access to inspection openings and enough air for the combustion, there needs to be a distance of
at least 8 cm to the wall behind. However, to ensure easy access during service and cleaning, we
recommend keeping a distance of min. 10 cm to the wall. You must be prepared to dismount the flue pipe
and turn the stove during the yearly inspection and by maintenance.
If the Aduro H2 is to be placed close to flammable material such as a wooden floor or carpet it must be
placed on a non-flammable base. The floor plate should extend for at least 30 cm in front of the Aduro H2
and 15 cm on each side –measured from the combustion chamber opening.
Please ensure that all local rules and regulations are complied with, including CE marking of the exhaust
connector. Additionally, distance requirements to flammable material for the exhaust connector must be
respected.
2.2 Pipe connection
Aduro H2 leaves the factory with the flue outlet mounted on the top. If you require the flue outlet on the back,
remove the round circle from the rear cover at the upper rear of the stove and then exchange the exhaust
connector (located on the top outlet above the stove) with the cover plate (that covers the rear outlet). The
top outlet is finished with the plate that lies in the ash pan. We recommend that you place a thin gasket
between the flue pipe and exhaust branch. A flue pipe with an internal diameter of 150 mm should be used
for Aduro stoves. Aduro H2 is tested and approved for use with an uninsulated fluepipe of minimum 100 cm.
The Aduro H2 must be installed on a floor with the adequate load-bearing
capacity. If the existing construction does not meet this requirement,
appropriate adaptation measures must be taken (e.g. a load-distributing plate).

56
2.3 Connection to a brick chimney
If the stove is being connected to a brick chimney, the rear outlet should be used, or a curved flue pipe via
the top outlet. After measurement, a hole is made in the chimney in which the pipe sleeve is placed, and
fireplace mortar is used to seal it in place. The stove is placed in position and the flue pipe is put in place. A
thin gasket is placed between the flue pipe and the pipe sleeve to seal the joints. The flue pipe should
protrude into the pipe sleeve but must not block the opening in the chimney (see the illustration below).
The Aduro H2 can be connected to a chimney to which other heat sources are connected.
2.4 Supply of combustion air
All wood burning stoves need constant supply of air to ensure a
clean and efficient combustion. This is often a problem in
modern energy-efficient houses that are very tight. Therefore,
the Aduro H2 is equipped with external supply of combustion
air, where the air to the combustion is supplied from the outside
and directly into the wood burning stove. Air from outside can
be provided through a channel, which is connected to the
connecting pipe under the combustion chamber. The amount of
air needed for combustion is 25 m3/h.
The connecting pipe has an external diameter of 78 mm, to
which you need a pipe with a diameter of 80 mm. If the
pipework is more than 100 cm, or if there are bends on the
tube, the resistance in the pipe increases significantly. Negative
pressure outside on the sheltered side of the house can also affect the resistance of the pipe significantly. In
these situations, the pipe should have a diameter of minimum 100 mm. It may also require a stronger
chimney draft, which you can achieve by installing an Aduro DraftOptimizer. You can easily test the
resistance in the pipe by opening a window close to the stove, disconnect the external air supply and then
light up the stove. If the combustion looks different than before, there is too much resistance in the external
air supply. If the pipe work is further than 1 m the pipe diameter must be increased to 100 mm and a
correspondingly larger wall valve must be chosen. In warm rooms the channel should be insulated with 30
mm mineral wool covered with a damp-proof course (plastic). It is important that the lead-in between the pipe
and the wall (or floor) is sealed with jointing compound. You can eventually use the complete Aduro fresh air
kit.

57
2.5 Aduro Hybrid App
It is possible to control Aduro H2 in three ways:
1. Through the control panel on the stove.
2. Through the app Aduro Hybrid and the Wi-Fi module “Aduro” in the near of the stove
3. Through the app Aduro Hybrid when the Wi-Fi module is connected to the router and connected to
Aduro Cloud. When your stove is connected to Aduro Cloud, it can be controlled remotely.
The app Aduro Hybrid is free and can be downloaded from App Store or Google Play.
Configuration of the app
1. Connect the stove to power outlet (see section 2.6).
2. Download the Aduro Hybrid app from either Google Play (Android) or App Store (Apple).
3. Follow the instructions in the guidance of the app or from our website www.adurofire.com/aduro-
hybrid under “Frequently asked questions” and “Wi-Fi connection”.
4. The serial number for operation (5-6 digits) and password for the app (10 digits) can be found on the
label inside the bottom front door. It looks like this:
5. Software and app are now updated to the newest version.
6. Now you are connected and able to operate using the app.
App features
The app has several features to choose from; heat level, desired room temperature, and timer/week
program. The timer/week program makes it possible to plan, how the stove should run during the week.
Control with Wi-Fi
Smartphone/Tablet
Router

0123456789

58
The frontpage of the app shows:
1. Power status
2. Heat level
3. Smoke temperature
4. CO level (Safety measurement which measures whether there is smoke in the back of the system).
A green bar is OK. If the bar reaches yellow, the hybrid stove will lower its heat level to 1. If the bar
reaches red, the stove will turn off itself.
The CO sensor is located by the pellet inlet to prevent the stove from firing when the chimney draft is not
sufficient. The CO sensor could be affected by the pellets. Some pellet bags have a high level of CO that can
affect the sensor up to 24 hours after loading the stove with pellets. If this problem occurs, you can open the
door to the pellet container and add fresh air to the room until the CO level has dropped.
2.5.1 How to connect the stove to the internet
For successful connection, there must be a stable Wi-Fi signal where the stove is installed. In case of weak
or unstable signal, the use of the stove could be affected.
It is recommended to install the stove where there is a maximum Wi-Fi signal with 3 out of 3 or 4 out of
4 . Your smartphone/tablet must be connected to the local Wi-Fi network. If you experience any
difficulties controlling the stove via the smartphone/tablet, it is due to the fact that the smartphone/tablet has
a control system that does not meet our requirements (See 2.5). If you are able to control the stove through
the smartphone/tablet but can’t connect the stove to the Wi-Fi router, the router is too old and/or the signal
too weak. If this is the case, we recommend you to buy a new router with a strong signal and a Wi-Fi
amplifier that is located somewhere between the router and the stove.
If other electronic devices work well in the house, but the hybrid stove can’t be connected, it is due to the fact
that the hybrid stove requires a stronger Wi-Fi signal than other electronic devices.
2.6 Electrical connection
Aduro H2 comes with approx. 1.5 meter of cord with an Euro-plug, that should be connected to a 230V /
50Hz outlet. Power consumption during operation is approx. 33 watts. The cord must be positioned so it is
not in contact with hot surfaces or pointed objects.
2.7 Register your stove on Aduro Cloud
We highly recommend that you register your hybrid stove on our cloud www.adurocloud.com as soon as the
stove is connected to your Wi-Fi router. By registering your stove, you will have access and overview of your
stove’s data – what it does, how it burns (graphs, statistics, logs, settings) etc. When your stove is registered,
At our website you can find more information on how to configurate the Wi-Fi.
Go to https://www.adurofire.com/aduro-hybrid/ under “Frequently asked questions”
and “Wi-Fi connection”.

59
it is helpful for you as a user, but also helpful for us and the craftsmen, if something happens to the stove, or
when it needs the yearly service visit from a professional. In Aduro Customer Service you can find a
guideline on how to access the cloud. You can access the service center here.
3. Lighting a fire in the Aduro H2
You can light the fire using just pellets or light it manually with wood –or a combination where you put
firewood in the combustion chamber and use the pellets to light the fire. We recommend a combined usage,
since firing with wood gives a higher temperature which burn the remains of the pellets.
Important safety information
•The Aduro H2 will become warm during use and therefore it should be treated with all necessary
caution.
•Never keep easily combustible fluids such as petrol in the near of the Aduro H2.
•Never use easily combustible fluids to light the fire in the Aduro H2.
•When lighting a fire, it is important to get the fire burning fast. If the fire does not start quickly and
wood only smoulders, it can cause strong smoke formation and in worst case cause an explosive
ignition of the flue gasses, which can damage the stove.
•Never empty the ash pan when the Aduro H2 is warm. Embers may still be found in the ash pan
for up to 24 hours after the fire has gone out. Please wait to empty the ash pan until you are sure
that there are no embers in the ash.
•The door should be kept closed while the Aduro H2 is in use. While lighting the fire, the door can
stand ajar for the first few minutes.
•The pellet function stops if the door is opened.
•When putting logs in a hot stove, you must always open the primary air intake and make sure that
the wood ignites within 2-3 minutes. If the wood does not ignite, add some ignition products and
ignite them manually.
•In the event of a chimney fire: Close all the dampers on the Aduro H2 and call the fire-fighting
service.
3.1 Damper
The stove is equipped with a damper under the door, which regulates the combustion air: primary,
secondary, and tertiary air supply. The primary air is used at the beginning to get the fire going, the
secondary air keeps the fire burning evenly, and the tertiary air ensures that flue gasses are burned. You
must always add secondary and tertiary air, while firing the stove. According to our experiences regarding
the use of the pellet function, we recommend that the damper is always completely closed to achieve the
optimum combustion of the pellets.
The damper allows you to adjust the Aduro H2 according to the chimney draft and the heat output, you
require. The longer the damper is pulled out, the more air is added and the more powerful the combustion.
The illustration below shows the stove seen from the front with the dampers indicated. Use edge of door to
read position of inlet air:

60
3.1.1 Secondary air supply
In normal circumstances, the Aduro H2 should be working with this damper between 60 % and 100 % open
(the damper is placed between position 2 and 3). You should never close the air intake so far that the flames
are extinguished. There should always be visible flames in order to achieve clean and efficient combustion.
A too low supply of air can lead to bad combustion, high emissions and a bad efficiency.
If you wish to fire the stove with the lowest effect possible –around 3 kW –you must close the secondary air
supply almost completely 45 minutes after the wood has been put in. At this point there are only few flames
and the stove can burn clean by using the tertiary air from behind in the stove.
3.1.2 Primary damper
When you add a new log, the primary damper should be opened until the fire is burning properly. In order to
utilize the fuel to the fullest extent, the embers should have burnt for so long that it is necessary to open the
primary damper for approx. 2 minutes to get the new log to burn.
In order to reduce the risk of ash falling from the stove when the door is opened to add more fuel, it is a good
idea to open the primary damper for approx. 1 minute before the door is opened. This increases the draft
through the stove and reduces the risk that ash will drop on the floor.
3.2 Aduro-tronic
The patent-applied control Aduro-tronic is a manually operated mechanical start-up
device, which works without the use of electricity and automatically regulates the
combustion. All you have to do is put dry wood in the stove and activate the control
system. Aduro-tronic does the rest, leaving you to enjoy the flames, the benefits of
efficient combustion, and a reduced firewood usage up to 40 %. For further
information, go to www.adurofire.com.
If you overload the Aduro H2 and burn more than approx. 3.1 kg wood per hour,
there is a risk that the lacquered surface of the stove will become discolored
and eventually fall off. The stove can be repainted, but this is not covered by
the manufacturer’s guarantee. In the same way, any other damage to the stove
caused by overloading will not be covered by the warranty. If the smoke
temperature exceeds 350 degrees, it can damage the gear motor.
1: Fully open primary, secondary, and tertiary air inlet. This
position can be maintained with the Aduro key, which must be
placed in the two holes.
2: Closed primary air inlet, fully open secondary- and tertiary
air inlet.
3: Closed primary air inlet, half way closed secondary air inlet
and fully open tertiary air inlet.
4: Closed primary and secondary air inlet, fully open tertiary air
inlet.
5: Regulator pushed all the way in. All air inlet closed (only
used when burning wood pellets).

61
3.2.1 How to operate Aduro-tronic
When lighting with wood only
When lighting a fire in the Aduro H2 for the first time, the maximum
amount of primary air will be needed to light the fire. For that reason, the
primary damper can be kept “forcibly open”. This is done by pulling the
primary damper forward as far as possible and then fixing it with the
Aduro Key (see illustration). When the stove is warm and a layer of
embers has been created on the bottom of the combustion chamber, the
Aduro-tronic can be set to the automatic position, i.e. the Aduro Key can
be removed. Alternatively, you can leave the door ajar the first minutes
during lighting the fire (without the key).
When stoking
Each time fresh wood is put in the stove, a precise amount of primary air
will be allowed in for the first few minutes. What’s more important is that
the primary air is not allowed in for too long. This is to ensure optimum combustion. The Aduro-tronic control
will ensure intake of primary air at the right tempo. The automatic is activated by pulling the primary damper
out each time fresh wood is put in the stove. The automatic closes then the primary air gradually.
Regulation of the Aduro-tronic control
The control is pre-set to close the primary air intake within 6 minutes. This setting has been used during
testing at the Danish Technological Institute using a standard chimney and ‘standard’ sized logs (approx. 30
cm long, 10x10 cm thick) with maximum moisture content of 18%. In practice, such circumstances can differ,
which is why the Aduro-tronic control can be adjusted to your circumstances. If you want a slower intake of
primary air (e.g. for a slower flue draft, larger sized wood or for longer intervals between stoking), adjust the
screw on the front of the control level using a small allen key to slow closure rate. If the screw is turned to the
right closing time is increased and if turned to the left closing time is reduced.
3.3 How do I light the fire in my Aduro H2?
During transportation, it may happen that the exhaust deflector in steel falls
out of place. Therefore, before using the stove, please make sure that the
exhaust deflector is properly placed (on the hooks or fastened to the bolts
depending on the model) for optimum combustion and preventing soot on
the glass.
If you only want to use your Aduro H2 with wood, the hybrid stove has a
damper (see illustration) for closing the pellet combustion manually. The
pellet function does not work when this damper is closed. The damper is
necessary, as you need to close the air to the pellet combustion to achieve
the most optimum combustion of the wood. However, if using both pellets
and wood, the damper must be open (pulled forward).

62
3.3.1 The first time a fire is lit
During the first firing, which should be carried out using approximately 1 kg of wood, the stoking door must
be left slightly open and must not be closed until the stove is cold. This is to prevent the sealing rope sticking
to the stove.
The first few times the Aduro H2 is used, there may be some smoke and unpleasant odours from the Aduro
H2, which is fairly normal. This is caused by the heat-resistant paint hardening. Make sure there is sufficient
ventilation during this stage. It is also important not to let the fire burn too fiercely the first 2-3 times, so that
the Aduro H2 has time to expand slowly. You should also be aware that the stove may make clicking sounds
as it heats up and cools down –rather like pouring boiling water into a sink. These are caused by the great
differences in temperature to which the materials are being exposed.
3.3.2 Lighting the fire manually with firewood
The fire lighting method is very important for starting combustion quickly and efficient.
1. Pull the damper under the door fully out so that primary, secondary, and tertiary air supply is
completely open.
2. Place a log of wood crosswise in the combustion chamber and put 2 firelighters close to the log.
Light the firelighters and quickly put a new log close to the firelighters and several small logs at an
angle above it. Air must be able to reach the firelighters, but the logs should be touching to “warm”
each other.
3. Keep the door approx. 1 cm ajar, until the glass is too hot to touch. Then close the door. When there
are distinct, visible flames and the fire has taken hold, close the primary air intake.
3.3.3 How do I add pellets?
Place the enclosed funnel in the opening of the pellet box and add the pellets. The pellets are distributed
with a poker in the box to make use of the entire capacity (approx. 13 kg of pellets).
By the first use, the augers must be filled with pellets:
Open the door to the combustion chamber and lift out the front of the
brazier (the black cast iron cone with the Aduro logo) so you can see the
pellets. Close the stove’s door. Press and hold the AUGER button and
the augers will start transporting the pellets (only at OFF mode yellow
button). After approx. 12 minutes where you press and hold the AUGER
button, the auger pipe will be filled with pellets. Stop pressing the AUGER
button when the pellets are about 2 cm under the auger pipe’s top edge.
Insert the brazier and close the stove’s door. In section 5 you will find an
overview of the different alarms.
The control handle will get warm when the Aduro H2 is in use. Please use the
glove provided when you operate the Aduro H2.

63
3.3.4 Lighting the fire with pellets
Before the pellet function of the stove is turned on, you should ensure that there are enough pellets
underneath the brazier. You can do this by moving the brazier to the side. If there are pellets up to around 1
cm under the edge of the auger tube, there are enough pellets. You can now put the brazier back in place.
Remember to check that it is placed correctly and fits tightly. Then, you can turn on the stove.
Push the ON/OFF button and wait until the ON button displays a constant green colour. The lighting of the
fire will then start automatically, and the pellet burner will start. When the stove is lighting, the combustion
chamber will be filled with smoke until the ignition starts. After approx. 6 minutes flames should appear.
Normal use should be achieved after 15-20 minutes.
When the smoke temperature reaches 90 degrees, the stove will shift from the “warm up mode” to “normal
mode” and continue with the last settings. You can manually change between 3 heat levels without using the
app by pushing the logo with an auger, which is placed directly under the ON/OFF button on the display.
•Step 3 (100 % operation): ‘ON button’ lights green constantly.
•Step 2 (50 % operation): ‘ON button’ flashes quickly.
•Step 1 (10 % operation): ‘ON button’ flashes slowly.
When you want to switch of the pellet burner, push the ON/OFF button or use the app.
If you experience that the stove does not turn on in the first or second attempt but instead shows the alarm
“ignition failed”, it is important that you do not try to turn on the stove again. Instead, wait until there is no
more smoke in the combustion chamber, and then move the brazier to the side and scrape the pellets away
if they have accumulated. You can now put the brazier back in place. Remember to check if it is placed
correctly. Then, you can turn on the stove again. The alarm “ignition failed” is often caused by an insufficient
chimney draft. You can create chimney draft by igniting some paper or small pieces of firewood - this can
sometimes remove pockets of air in the chimney.
The pellet function can burn up to 24 hours on a full pellet container at level 1, 12 hours at level 2, and 8
hours at level 3. The stove is capable of running day and night, if pellets are added in time.
3.3.5 Lighting the fire with wood and pellets at the same time
Cold stove
Put dry wood in the combustion chamber - just as if you wanted to start the stove manually (see section
3.3.1). However, you won’t need any firelighters. The fire is lid with pellets. It will be an advantage, if you
start with a closed air inlet until the fire is burning in the pellet burner. After this, you can open the air inlet for
Brazier

easier lighting of the firewood. When the logs have caught fire and the smoke temperature is about 280
degrees, the pellet supply will stop automatically.
The stove in pellet operation
When the stove is in pellet operation, you can always add firewood –you just have to remember to close the
door within 3 minutes. Open the door carefully and the pellet supply will stop and the ALARM flashes red.
Add firewood of the correct quality and respect the MAX load line. Close the door again. The stove will now
continue combustion of pellets. When the logs are burning and the smoke temperature is about 280 degrees,
the pellet supply stops automatically. After this, the stove will change to WOOD BURNING mode.
It may occur that the temperature rises above 300 degrees when using pellet operation on heat level 3. If this
happens, the pellet supply stops automatically and the stove will shift to wood burning mode. To avoid this,
reduce the amount of pellets at heat level 3. This is done in the service menu by choosing “auger”.
If you use the function "Heat Level" on the app and want the stove to restart automatically
on pellets when the wood has burned out, you can set the Aduro Hybrid on standby mode
with just 1 click on the button (see illustration). The stove will now be in standby mode and
await a smoke temperature below 100 degrees before it starts the pellet combustion and
ignites again. However, if you use the function "Desired Room Temperature", the Hybrid will
start automatically again when the smoke temperature is below 100 degrees.
IMPORTANT!
If the door to the combustion chamber is open for more than 3 minutes, the pellet combustion will shut
down and must be started again by pushing ON/OFF. The stove starts when the smoke temperature is
below 100 degrees. If the stove flashes green ON, it means that the stove will start, but is waiting for the
smoke temperature to be below 100 degrees C or timer.
When you want to switch off the pellet burner, push the ON/OFF button. If you open the stove door during
operation, the red ALARM will light. If you close the door before 3 minutes, the pellet burner goes back to
ON mode automatically.
3.4 How should I use my Aduro H2?
The Aduro H2 is intended for intermittent combustion. This means that each stoking should burn down to
embers before new logs are added.
In order to obtain the best possible combustion, you should regulate the effect/heat output with the fuel.
Burning small logs provides more powerful combustion than burning large logs as the surface area is greater
and more gas is released. The amount of wood in the combustion chamber is another factor that affects
combustion. The optimum combustion is achieved by adding two pieces of logs. If you want an enhanced
effect, you can add more logs. The nominal heat output is reached by burning approx. 1.5 kg per hour,
divided between 3 pieces with a length of approx. 21 cm.
If you experience problems lighting the fire or the fire dies after a short time, it can be due to the following
reasons:
•The firewood is not dry enough. The firewood should have a moisture content of max. 18%.
•There is a negative pressure in the house.

65
•The smoke outlet from the outside may be blocked from sooth. This can occur after chimney
sweeping. Control the smoke outlet.
•The used amount of wood may have been too small. Therefore, the embers were too weak and cold
to light the next load of wood.
3.5 Recommended fuels
3.5.1 Wood and wood briquettes
Wood that has been stored indoors has a tendency to become too dry and will burn too quickly. We
recommend that you fell the wood in the winter, when a lot of the moisture in the wood will have been drawn
down into the roots. In order to achieve optimum combustion, the wood’s moisture level should not exceed
18 %, which roughly corresponds to storing the wood under cover outdoors for one year. The moisture level
of the wood can be measured using a moisture meter or by applying washing up liquid to one end of the log
and blowing air in the other end. If the wood is dry enough, soap bubbles will appear. The wood should be
chopped into logs with a diameter of approx. 10 cm and a log length of max. 39 cm.
Correct firing provides optimum heat output and maximum economy. At the same time, correct firing
prevents environmental damage in the form of smoke and malodorous fumes and also reduces the risk of
chimney fires. Well-seasoned wood fuel is essential for correct use. Make sure your fuel is kept dry. If the
fuel is wet, a large proportion of the heat will be used to vaporize the water, and this energy will disappear up
the chimney. It is clearly not only uneconomical to fire with wet fuel but also, as mentioned above, increases
the risk of producing soot, smoke and other environmentally damaging by-products.
Burning varnished wood, impregnated wood, chipboard, paper and other waste is strictly forbidden. Burning
these materials will damage the environment, the Aduro H2 and your own health. Fossil fuels must not be
used.
3.5.2 Pellets
You can only use Ø6 mm pellets with a maximum length of 40 mm –type ENplus quality A1. We recommend
that you use pellets of a good quality –and preferably bright pellets instead of dark pellets. The quality of the
wooden pellets has a direct influence on the noise level, the efficiency, and the cleaning interval of the stove.
It is important that the pellets are kept dry, as moist pellets can reduce the nominal heat output by up to 50%.
When the firing season is coming to an end, it is important to completely remove all pellets from the pellet
container and the augers. If you don't do this, material damage can occur when you start using the stove
again.
At our website www.adurofire.com/aduro-hybrid you can find more information.
The brazier must not be removed during use with either wood nor pellets
(doesn’t apply when conducting a fast cleaning under the brazier to clean out
ash and cinders). Never use wood with nails and other objects that can damage
the auger carrying the pellets. Never place pellets in the combustion chamber.
Pellets must be supplied from the pellet container.

4. The chimney
The optimum combustion is achieved at a constant chimney draft of 10-14 Pascal (Pa) measured in the flue
pipe above the stove (when having a smoke exhauster). However, with natural draft (chimney without smoke
exhauster) the draft in the chimney will be between 18-25 Pa when conditions are optimum. There are many
factors that affect the chimney draft, including the outside temperature, wind strength, and surrounding
buildings. There are no requirements with respect to specific chimney heights, but a chimney must be tall
enough to provide a good draft. If the recommended chimney draft is not achieved, there may be problems
with smoke out of the door by firing.

4.1 Inadequate draft in the chimney
If you experience poor draft in the stove after the installation, please make sure that there is nothing in the
chimney to restrict the smoke and that no nearby buildings or trees affect the winds around the chimney.
If the chimney is too short, leaks, or is inadequately insulated, there may be problems with the chimney draft
(let the chimney sweep assess this). The draft should be sufficient during the ignition phase when the
stove/chimney is cold to provide a clean combustion and prevent smoke leakage. Therefore, we recommend
a chimney draft around 5 Pa in the ignition phase.
Once the ignition is a success and the smoke temperature is rising, it is important that the chimney draft
reaches a stable area around 18-25 Pa in operation (1 hour after ignition) when the chimney/stove is hot.
The draft in the area of 18-25 Pa when the stove is hot is essential in order to achieve an optimum and clean
combustion and avoid problems such as pellet accumulation and smoke leakage. Therefore, we recommend
that you measure your chimney draft when the chimney is cold and when it is hot after 1 hour in operation.
In practice, the chimney draft will differ –especially in cold condition. Therefore, the best indication of the
chimney draft is to measure the draft when it is hot. If the chimney sweep judges the draft to be sufficient, but
you still have problems lighting a fire in “wood mode”, try extending the fire lighting phase by using more thin
pieces of kindling and 1-2 firelighters, so that the chimney gets thoroughly warm. The chimney will not draw
at optimum effect until it is warm. When a layer of embers has been formed, add 2-3 dry logs.
When in "pellet mode", the stove will not be able to ignite and instead give the alarm “failed ignition” if there
is not enough chimney draft in the ignition phase. If you experience that the stove does not turn on in the first
or second attempt but instead shows the alarm “ignition failed”, it is important that you do not try to turn on
the stove again. Instead, wait until there is no more smoke in the combustion chamber, and then move the
brazier to the side and scrape the pellets away if they have accumulated. You can now put the brazier back
in place. Remember to check if it is placed correctly. Then, you can turn on the stove again. The alarm
“ignition failed” is often caused by an insufficient chimney draft. You can create chimney draft by igniting
some paper or small pieces of firewood - this can sometimes remove pockets of air in the chimney.
If it is impossible to establish a sufficiently natural chimney draft, the chimney can be fitted with a smoke
exhauster, e.g. Aduro DraftOptimizer.

67
4.2 Chimney and Smoke
If you experience smoke coming out of the stove or the start section of the smoke pipe, it could be due to
certain weather conditions. On stormy or cold winter days or if the chimney has not been used in a while, a
cold plug can be created in the chimney, meaning the natural draft will be at its minimum.
If the chimney is cold and cold plugs are created, you may experience smoke leaks during the ignition and
startup phase. In this situation there can be more smoke than usually in the combustion chamber and some
of it might leak out of the stove. Therefore, if you have a cold chimney that has not been used for a while, we
recommend that you use some wood sticks to heat the chimney and eliminate the cold plug before turning
the pellet function on.
4.3 Draft and pellet combustion
The pellet combustion is affected by the draft in the chimney. If necessary, it is important to reduce or
improve the draft with a damper in the chimney or with a smoke exhauster, e.g. Aduro DraftOptimizer, if the
draft is too high or insufficient.
You can connect Aduro DraftOptimizer to Aduro H2 and control it automatically to ensure optimum draft. For
further information, go to www.adurofire.com.
Aduro Hybrid has certain standard settings when it comes to the speed of the auger and the fan, and in order
to achieve the most efficient / clean pellet combustion, it may sometimes be necessary for the user to adjust
these settings to customize the stove to their own installation such as chimney, smoke pipe, external factors
from the outside etc. If you're interested in knowing more about the app's features/functions, calibration, and
various FAQ’s, then you can read more about it on our website www.adurofire.com.
Below 3 examples of pellet combustion, depending on the draft level:
Optimum flame
Flame generates high quantity of ”sparkles” = the chimney draft is too high

68
Flame is low and brazier is overflown = the chimney draft is not sufficient
You can partly compensate for an inadequate chimney draft by increasing the fan speed on the hybrid stove.
This is done in the service menu of the app.
5. Control of Aduro H2
Aduro H2 has the following ALARM modes where pellet delivery must be stopped immediately:
•SMOKE SENSOR: smoke sensor defect.
•SHAFT SENSOR: shaft sensor defect.
•TERMO: shaft sensor too hot.
•DOOR CONTACT: door open.
•PELLET DAMPER: damper closed.
•EXIT: defect exit for external auger.
•FUEL: smoke temperature too low after more than an hour of operation –no fuel?
•LIGHTING: smoke temperature not reached after two attempts to light the fire.
•CO: CO (carbon monoxide) level is too high.
Here the ALARM will light red. When the cause of alarm has been rectified, the stove can be started by
pushing ON/OFF twice.

69
The development within phones and electronics continuously provides new possibilities and demands for
updates and developments of the app. When you buy an Aduro Hybrid stove, updates of the app and control
system are included 5 years after purchase. After this, charges may apply for updates.
6. Maintenance of the stove
6.1 Daily maintenance –when using pellets
When you add pellets, you should brush the brazier free from of ashes and cinders. Open the door to the
combustion chamber and lift the front of the brazier (the black cast iron cone with the Aduro logo). Brush the
ashes and the cinders through the grate to the ash pan. Avoid brushing ashes and cinders down into the
pellet auger. Put back the front of the brazier.
Empty the ashpan when needed.
All maintenance and cleaning of the Aduro H2 should be carried out when the
stove is cold and power disconnected.

70
Brazier
We recommend two types of maintenance during the week: a short cleaning while the stove is lit (cannot last
more than 3 minutes because of the sensor in the door) and a thorough cleaning where the stove is turned
off and cold. We recommend that you conduct the short cleaning 2 times a day and the thorough cleaning
every 4 days.
During the short cleaning, the stove must be cleaned under the brazier. We recommend that you use gloves.
By using a tong or a similar tool, you can move the brazier to the side and clean out ash and cinders. Put the
brazier back in place. During the thorough cleaning, the fireproof tiles must be removed, and the auger and
the combustion chamber must be vacuumed thoroughly.
6.2 Regularly maintenance –when needed
Ashes
Empty the ashpan before it gets completely full. Always leave a layer of ashes in the stove because it
insulates and makes it easier to light a fire.
Remove the brazier and clean the top auger for ashes with a vacuum cleaner. This is done easiest by
making a "paper ring" of paper roll, which is laid around the opening of the auger. Then press the vacuum
cleaner muzzle down towards the "paper ring" so it fits tightly. After this, the ashes can be vacuumed up.
Glass
Wet wood, insufficient chimney draft, and wrong use of the hybrid stove can leave soot stains on the glass.
They can easily be removed using a damp cloth that you dip in cold ash and rub on the sooty glass. Special
cleaning agents are also available to remove soot from glass, e.g. the Aduro Easy Clean pad. The pad
neither scratches nor damages the glass, and it can be used multiple times. Water or other cleaning agents
are not necessary.
It is common maintenance to tighten the glass fittings and the hinges shortly after the stove has been
installed as well as to check if the gaskets are properly placed.
Pellet container
Burn all pellets and brush the container clean.
6.3 Periodically maintenance –after about 500 hours of use
If the stove is placed in dusty surroundings, it can be necessary to clean the ventilator. Clean the brazier for
ash and cinders, e.g. with a scraper. Clean the air pathway for electrical igniter for ash and cinders that might
be covering the hole placed on the left side of the tube under the brazier, e.g. using a small, straight
screwdriver.
For further information regarding maintenance of the stove, please go to www.adurofire.com.
6.4 Yearly maintenance
The yearly maintenance must be conducted by a professional. Contact your local Aduro GO partner for
further information as rules for chimney sweeping and stove maintenance differ from area to area.
