For the purposes of the guarantee and for other enquiries, it is important that you are able to quote this number.
HOW TO SUCCEED WITH YOUR NEW WOOD BURNING STOVE
In Aduro’s Customer Service Center you will find tips and tricks on how to succeed with your new Asgård wood burning stove. Here you will have direct access to interesting content about maintenance of your stove as well as support related information.

General

The wood burning stove complies with the European Directive Ecodesign 2022, the EN13240 European standard 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. DoC (Declaration of Conformity) can be downloaded at www.adurofire.com/download/.
1.2 Transportation
When taking your wood burning stove home, please ensure that it travels in an upright position. If you wish to lay it flat, it is important that you remove all loose parts from the combustion chamber (cast iron grate, baffle plates, and insulation tiles) and remove the ashpan. Otherwise, you can leave the insulation tiles and the cast iron grate in the combustion chamber and then fill it up with surplus packaging to secure the loose parts.

Installation of the stove

You may install your wood burning stove yourself – but we strongly recommend that you consult your chimney sweep before beginning the installation. 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.
Your dealer can also provide you with installation advice. Remember, it is your responsibility that rules in force are complied with.
APPLIES TO UK INSTALLATION ONLY: To comply with UK building regulations an approved CO monitor should be installed in the same room as the appliance.
You may not begin to use the stove until it has been inspected and approved by your local chimney sweep.

2.1 Position of the stove / distance requirements
Distance requirements will only apply if the wood burning stove is to be placed close to flammable materials:

Distance to flammable material (cm)| To the sides (A)| Behind the stove (B)| Distance to furniture (C)| Above the stove
---|---|---|---|---
Asgard 1| 30| 10| 85| 50
Asgard 2| 30| 10| 85| 50
Asgard 3| 30| 25| 100| 50
Asgard 9| 30| 10| 85| 50

If the stove is positioned against a brick wall or other non-flammable material, there are no minimum distance requirements. To facilitate cleaning and for the best use of the convection air, we recommend that you leave approx. 5-10 cm to the wall.
If the wood burning stove is to be placed on a 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 wood burning stove and 15 cm on each side measured from the opening of the combustion chamber.
The wood burning stove must be installed on a floor with the adequate loadbearing capacity. If the existing construction does not meet this requirement, appropriate adaptation measures must be taken (e.g., a load- distributing plate).

2.2 Pipe connection
Please ensure that all local rules and regulations are complied with, including CE marking of the flue pipe.
Additionally, distance requirements to flammable material for the pipe must be respected.
The stove leaves the factory with the flue outlet mounted on the top. A flue pipe with an internal diameter of 150 mm should be used for all Asgård stoves.

2.3 Connection to a brick chimney
If the stove is being connected to a brick chimney, a curved flue pipe should be used. After measuring, a hole is made in the chimney in which the pipe sleeve is placed, and stove 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). You may benefit from putting a slim gasket between the flue outlet on the stove and the flue pipe. You may benefit from putting a slim gasket between the flue outlet on the stove and the flue pipe.
2.4 Transport handle
The stove comes with a temporary transport handle, which should be replaced with the permanent handle found inside the stove upon installation.

Lighting the stove

Important safety information:

The wood burning stove 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 vicinity of the wood burning stove.
Never use easily combustible fluids to light the fire in the wood burning stove.
When lighting a fire and adding new wood logs, 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 ashpan when the wood burning stove is warm. Embers may still be found in the ashpan for up to 24 hours after the fire has gone out. Please wait to empty the ashpan until you are sure that there are no embers in the ash.
The door should be kept closed while the wood burning stove is in use. While lighting the fire, the door can stand ajar for the first few minutes.
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. Please make sure that the flames are burning steadily for the first 10 minutes before you leave the stove.
In the event of a chimney fire: Close all the dampers on the wood burning stove and call the firefighting service.

3.1 Damper
The stove is equipped with air dampers for regulation of the primary and secondary air supply. The primary air is used at the beginning to get the fire going, and the secondary air keeps the fire burning evenly. The tertiary air ensures that flue gasses are burned and is not adjustable. You must always add secondary and tertiary air, while firing the stove.

3.1.1 Primary damper
When you add new logs, the primary damper should be opened until the fire is burning properly. In order to utilise 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 logs burning. However, it is important to fire at a certain time so that the flames do not go out during the closing time for the Aduro-tronic.
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.
3.1.2 Secondary damper
The secondary damper behind the door allows you to adjust the wood burning stove to the chimney draft and the required heat output. Turning the damper to the left decreases the air supply and turning to the right increases the air supply. In normal circumstances, the wood burning stove should be working with this damper open between 60 % and 100 %. You should never close the air supply so far that the flames go out. There should always be visible flames in order to achieve a clean and efficient combustion. A too low supply of air can lead to bad combustion, high emissions, and a low efficiency. The air-wash system that minimises soot on the front glass is also adjusted by this damper.
If you want to fire in the stove with the lowest possible effect – around 3 kW – you must close the secondary damper almost completely approx. 45 minutes after stoking. At this point there are only few flames, and the stove can burn clean by using the tertiary air from the back of the combustion chamber.

3.2 Ventilation / fresh air supply
In order for the wood burning stove to function at optimum efficiency, air is needed for the combustion process. There must be sufficient fresh air coming into the room where the wood burning stove is placed. In very well-insulated houses or houses with powerful cooker hoods and/or air conditioning systems, a vacuum can be created around the wood burning stove, leading to smoke leakage and poor combustion. In these circumstances, it might be necessary to open a window to provide air for the combustion and to equalize the vacuum. Alternatively, you could place an air vent in the room where the wood burning stove is placed. The amount of air needed for the combustion is 25 m3/h.

3.3 How should I use my wood burning stove?
The wood burning stove is intended for intermittent combustion. This means that each stoking should burn down to embers before new logs are added.
You can regulate the effect/heat output with the fuel. Burning small logs provides more powerful combustion than burning large logs. The ideal heat output is reached by burning approx. 1.3 kg wood per hour.
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. See section 3.2.
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. This results in a too little and too cold layer of embers which cannot light the new wood.

If you overload the wood burning stove and burn more than the recommended amount of wood per hour (see section 1.3), there is a risk that the surface of the stove will become discoloured and eventually fall off. The stove can be resurfaced.

3.4 The first time a fire is lit
The wood burning stove is packed in recycling packaging. The wood from the packaging can be sawed into smaller pieces and used the first few times a fire is lit. The plastic packaging must be disposed according to national rules regarding disposal of waste.
The first few times the wood burning stove is used, there may be some smoke and unpleasant odours from the wood burning stove, 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 wood burning stove has time to expand slowly.
You should also be aware that the stove may make some clicking sounds as it heats up and cools down – like pouring boiling water into a sink. These are caused by the great differences in temperature to which the materials are being exposed.
During the first firing, which should be carried out using approximately 1 kg of wood, the door must be left slightly open and must not be closed until the stove is cold. This is to prevent the gaskets from sticking to the stove.

3.5 Lighting a fire in the wood burning stove
How you light a fire is very important for a quick and efficient ignition phase. Follow these instructions when lighting the stove:

Open the primary damper at the bottom of the door and the secondary damper at the top of the door.
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.
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 damper.

The control handles will get warm when the wood burning stove is in use.
Please use the glove provided when you operate the wood burning stove.
3.6 Recommended fuels
We recommend the use of split hardwood that has been stored outdoors under cover for at least 1 year.
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 during 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 outdoors under a cover for one year. The moisture level of the wood can be measured using a wood moisture meter or by applying dishwashing 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 length of max 32 cm (Asgard 1, 2 & 9) / max 35 cm (Asgård 3). Firing with wet fuel will reduce the energy efficiency and increase the particle emission.
Burning varnished wood, impregnated wood, chipboard, paper, and other waste is strictly forbidden. Burning these materials will damage the environment, the wood burning stove, and your own health. Fossil fuels must not be used.

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. Therefore, we recommend that you measure the 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, try extending the ignition 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.
If it is impossible to establish a sufficient natural chimney draft, you can mount a smoke exhauster, e.g. Aduro DraftOptimizer.

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.

Maintenance and cleaning of the stove

All maintenance and cleaning of the stove should be carried out when the stove is cold.

Combustion chamber
The fireproof tiles in the combustion chamber eventually wear out and should be replaced when the cracks are more than 0.5 cm wide. The durability of the tiles depends on how often and how intensively the stove is used. You can change the tiles yourself. They are available as a ready-to-use set. You can buy the sets at www.aduroshop.com.
Glass
Wet wood, unsatisfactory chimney draft, and wrong use of the stove can leave soot stains on the glass panes. It 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 is for multiple usage. 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.
Gaskets
Check if the gaskets around glass and door are properly placed. Over time, the gaskets will wear out and should therefore be checked regularly. If leakages appear, they should be replaced, as it is essential that the stove is tight.
Adjusting the door
Adjusting the door and the closing mechanism is a necessary part of the maintenance of the stove, which you can easily do yourself. If the door hangs on one side, feels sluggish to close or does not close properly, you should adjust and tighten the hinges and fittings around the door.
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.
Cleaning the stove
The stove’s surface will stay at its best just by being vacuumed with a small, soft mouthpiece or dusted with a soft, dry cloth. Do not use spirit or other solvents, as they will remove the paint.
Do not clean the stove with water. If the stove is exposed to moisture, the stove may develop rust.
The inside of the stove and the flue pipe can be cleaned through the door or alternatively through the cleaning aperture in the flue pipe/chimney. The upper fireproof tile (the exhaust deflector) can be removed.
To allow free access to the top of the stove and the flue pipe, remove the exhaust deflector in steel. The flue pipe can be removed from the stove and cleaned. Cleaning of the inside of the stove and the flue pipe should be undertaken at least once a year, or more frequently if necessary, depending on how often the stove is used. This work can also be carried out by the chimney sweep or your local Aduro GO partner.
Repairing the surface
The stove is painted with a heat resistant paint that can withstand temperatures up to 500 degrees. If the surface of the stove gets scratched or worn, it can easily be renewed using this type of paint. The paint is available in black metallic at www.aduroshop.com/aduro-spray-black-metallic- 53262a.
Spare parts and unauthorized alterations
You may only use original spare parts for your stove. All forms of unauthorized alterations to the stove are strictly forbidden, as the stove will no longer comply with the approved specifications. At www.aduroshop.com you can buy original spare parts for your stove.
