2. Requirements for Operating Your Wood-Burning Stove

2.1. External combustion air supply

Every combustion process requires oxygen. This oxygen is extracted from the environment of the heating appliance.
The exterior shell of modern buildings is very dense. As a result, insufficient fresh combustion air flows in, making an external supply of combustion air essential. This is also important if ventilation systems are used in the house.

NOTE!: The combustion air connection is marked on the back of the appliance with a supply air symbol.

Some appliance types may also be connected via the floor.
A pipe or hose with Ø125mm must be used to connect the external combustion air supply. The length of the pipe should not exceed 5m. This connection pipe may con-tain a maximum of three elbows.
If connected directly to the external wall, attention must be paid to the formation of condensate and to
the provision of wind protection at the inlet.
A lack of combustion air can cause poor combustion, in-creased soot formation and increased ash incidence.

2.2. Connection to the chimney

The information contained in this manual is of a general na-ture. National and European standards, local and building regulations, and fire safety provisions must also be observed and complied with.
The stove must be connected to a flue approved by the chimney sweep. Care must be taken to prevent condensa-tion from entering the stove.

NOTE!: The flue connection is marked with an exhaust gas symbol on the back of the appliance

The flue pipe must be connected in line with the technical data sheet. If you have any questions, please contact your dealer.

• The chimney must be laid out according to the technical data of the stove (see section: Technical Data).
• The horizontal length of the flue gas pipe should not exceed 2.5 m.
• A maximum number of 3 x 90° elbows should not be exceeded. Each elbow should be provided with a cleaning aperture.
• The chimney must be resistant to condensation.
• The chimney must provide at least 3-12 Pa draught to ensure the flue gases are sufficiently extracted, even in the event of a power failure.

2.3. Fuel

Pellets
We recommend using ENplus-A1 approved pellets.

NOTE!: Using inferior quality pellets
or other material will impair the functioning of your pellet stove and invalidate the warranty.

When storing the pellets, it is essential that they are kept in a cool, dry place and free from contamination.
Damp pellets impair combustion and clog the screw conveyor.

Firewood

Only use untreated, dry wood.
The wood moisture content should be < 15 %.
Basically, the amount of firewood fed determines the heat output. If significantly too much wood is fed, this can lead to overheating and damage to the stove. Damp wood causes poor combustion and exhaust gas values, as well as soiling of the viewing glass and the flue gas ducts.

2.4. Electrical connection

Your stove is designed for connection to a 230 V -50 Hz mains supply. The connection cable is included in the accessory pack.

The mains socket is located on the back of the appliance and is protected by a T2.5 A glass-tube fuse.

The power consumption of your appliance is indicated on the type plate.

3. Initial Operation, Using the Stove

First steps:

1. The stove must be connected to the flue. There must be a sufficient supply of combustion air.
2. Remove the accessories from the pellet hopper and the firebox. Fill the hopper with pellets and close the hopper lid.
3. Plug in the power cable and set the toggle switch on the back of the stove to “I “.
4. The display will now show the Austroflamm logo. This is followed by the main operating menu with temperature indicators and hopper level.
5. Before the initial start, the pellet worm conveyor must be filled. To do this, open and close the fire-box door. (Confirm the subsequent question on the display: “Have you inserted firewood?” with “YES”.) Next, start the manual filling process. For more detailed information, see the menu item: Manual pellet feed. This process takes about 5 minutes.
6. To start the stove in pellet mode, press the rotary knob for longer than 2 seconds or press “START” on the display.

3.1. Operating the stove via touch display

For installation and any other information, please contact your Austroflamm dealer.

Function- Fill level indicator

The fill level indicator informs you of the fill level of your pellet hopper. If the fill level falls below a certain value, a warning is shown on the dis- play. The fill level indicator must be updated manually each time the pellet hopper is filled.

Care should be taken to prevent the hopper from becoming com-pletely empty, otherwise the fire will go out unintentionally and you the screw conveyor will have to be filled manually before the next pel-let start.

The fill level indicator is calculated according to the size of the pellet hopper of your stove and the corresponding operating time. To en-sure the stove functions correctly, always fill the tank to the top, while setting the indicator to “FULL” at the same time.
Press the fill level icon in the room temperature indicator to set the display to “FULL”.
This function can be deactivated in the setting “Menu item: Fuel”.

‘Did you fill in Log wood?’

The answer to this key question will affect the further functioning and mode of operation of your stove. It will appear each time you close the firebox door.

Tap ‘Yes’ to switch to firewood mode or if you have put on new fire-wood. If you make no selection, ‘YES’ will be automatically selected after 10 seconds.

4. Operating modes of the stove

4.1. Functional diagram of your combi stove

4.2. Pellet mode

Automatic Ignition

The stove can be started with the Start/Stop button in the status display or heat output display.Optionally, it can be started via IR remote control or via the app.
Pellet ignition is fully automatic and occurs in several phases. These phases are shown on the display. (Positioning the riddling grate – filling the burner pot – ignition phase 1 – in-creasing the temperature in the firebox – ignition phase 2 – monitoring ignition – ignition phase 3 – release or control by the user – full combustion phase).
Pressing the Start/Stop button during the ignition phase terminates ignition. An error message “E102” will be displayed if ignition is interrupted.

Pellet mode

In pellet mode, the pellet quantity and combustion air are supplied in accordance with the heat output setting.
The room temperature required must be specified in the room temperature display. Once this is attained, the stove automatically regulates to the lowest output level or switches OFF, if the ECO function is enabled. (See Settings/ECO mode.)
Tapping the ‘STOP’ button switches the stove to the burn-out or cooling-down phase.
The current room temperature is measured by means of the wired temperature sensor on the rear side of the unit.
In pellet mode, a fluctuating flue draught or increasing fouling of the flue gas passes is automatically compensated by the flue gas fan. An error message is output only in ex-treme cases.

If the door is opened and closed again during pellet mode, the system switches to the op-erating phase ‘Hybrid start’.

4.3. Firewood mode

Heat output setting firewood ↔ amount of firewood
The heat output setting influences the automatic combustion process. To ensure optimal combustion, the output should be selected to match the amount of firewood inserted.
Output level 1: Ember maintenance (no firewood combustion)
Output level 2: approx. 1.0 kg of wood
Output level 3: approx. 1.4 kg of wood
Output level 4: approx. 1.7 kg of wood
Output level 5: approx. 2.0 kg of wood

Hybrid start

The hybrid start is used to ignite the firewood via pellet ignition. Here, pellets are in-jected and the air dampers for the combustion air supply are opened. This ensures that the firewood placed inside the stove burns optimally.
CAUTION: Make sure that the combustion recess is not completely covered with fire-wood (risk of deflagration).
After a few minutes the stove switches to the operating phase ‘Firewood start I’ to con-tinue inflaming the firewood.
If the door is opened and closed again during ‘Hybrid start'” and then ‘NO’ is tapped on the display, the stove switches back to pellet mode.

Firewood start I

Upon elapse of the ‘Hybrid start’ the furnace switches to this operating phase. Here it is en-sured that all pellets combust in the combustion bowl and that the firewood continues to be inflamed.
If the firebox door is opened and closed again when the stove is idle (and the question “Have you inserted firewood?” is answered with “Yes” on the display), the stove also changes to the operating status “Firewood start I”.
In this operating phase, all air dampers are fully open and the flue gas fan rotates at a given speed. After at-taining a specific firebox temperature and the elapse of a specific time, a switch to ‘Firewood start II’ is per-formed.
If no temperature increase is detected, the stove automatically switches to the ‘OFF’ state again. However, the stove remembers that firewood has been inserted. (A small green icon appears on the display.) After the next pellet ignition, the stove automatically switches over to ‘Hybrid start’.

Firewood start II
In this operating status, the riddling grate is opened after approx. 2 minutes. As a result, the primary air damper is closed and the firewod continues to be fanned until a certain temperature in the firebox is reached (depending on the selected heat output). Once this temperature has been obtained, the stove switches to the status “Firewood mode”.

Firewood mode
In this operating status, the stove automatically controls combustion of the firewood.
Depending on the output setting, the stove will attempt to maintain a specific firebox temperature. If this cannot be achieved, automatic switching to the next lower output level is performed in the background (not visible on the display). This achieves optimal combustion and ember maintenance of maximum duration in the burn-out process.

Power setting 1 is not suitable for burning newly inserted firewood.
This level is intended only for the purpose of achieving maintenance of the embers for as long as possible.

If the heat output is changed on the display, the combustion control is restored to the preset output.
If you change the heat output on the display, the combustion control is reset to the output setting.
If the firebox door is opened and closed again, the query ‘Have you inserted fire-wood?’ is shown on the display.
If you answer this with a ‘Yes’, a switch back to the status ‘Firewood start II’ is performed. This ensures the lighting-up of the new firewood.
If you answer this with a ‘No’, the stove remains in firewood mode status. Automatic con-trol is continued without having to light new firewood.
If no further firewood is put on, the stove automatically switches to burn-out and finally closes the dampers.
If the stove is not yet turned on at this point in time and the room temperature setting has not yet been attained, the stove will start automatically again in pellet mode.
Firewood mode with non-electrical operation
In an emergency the stove can be heated with firewood, without any electricity. In this emergency mode, the secondary damper is fully open at all times. Manual control is not possible.

CAUTION: for non-electrical operation a flue draught of at least 12 Pa is required.
Use sufficient kindling wood when lighting the fire, and when in heating mode, ensure the firewood added is of the right dimensions.

On stove models with an automatic riddling grate, the ashes on the riddling grate are tipped into the ash pan  each time the stove stops. The ash pan can be emptied as required.

The accumulation of flue ash in the combustion chamber is normal and should be removed once a week, if  the stove is in operation.

The burner pot and the riddling grate should be inspected every 2-3 days of operation to ensure that there  are no adhering deposits, and cleaned with a wire brush.

The tilting grate is closed by pressing the „Release Ash drawer“ button. This process takes about 90 seconds.  The ash drawer can then be removed.

This function is only possible in operating state „OFF“.

7. Replacement of the storage battery

A CR2032 storage battery is located in the control unit. This storage battery enables the control unit to save certain data – e.g. time, date, heating times etc. even during a power failure, or when the mains power supply is disconnected.
If the battery is flat, the control unit will continue to function normally. However, in the event of a power fail-ure, the above-mentioned data will be lost. These data must then be saved afresh.

Replace the battery every 2 years as follows:
1. The battery is located on the central control unit. To replace it, first remove the side panel on the right of the stove. Then detach the control unit cover.
2. Remove the old battery from the retainer using a pair of insulated pliers or a similar tool.
3. Insert the new battery, observing the correct polarity.

8. Guarantee / warranty

1. Warranty statement: For your AUSTROFLAMM pellet stove, we guarantee the flawless performance of the body for six years, and of all other steel and cast iron components for two years from the date of first sale. Steel and cast-iron parts and electrical and electronic components that manifest material- and or proces-sing defects during the guarantee period (warranty case) will be replaced for new parts provided that the warranty case has been asserted to the best of the holder’s knowledge within the statutory warranty pe-riod. Functional problems with electronic accessories (e.g. WLAN BOX, SmartSpot) shall only justify a war-ranty claim for the particular accessory. Our warranty only covers the free delivery of the new parts: work- and travel times are not recorded.
2. Exceptions: We do not provide a guarantee on wear parts (e.g. Keramott, seals and grate or combustion cavity, ignition cartridge, temperature sensor, flange bearing), surface coatings, varnish, glass and cera-mics. In the case of such defects no warranty case has occurred. When heating up, during operation and when cooling down, your pellet stove may produce some noise (crackling, soft clicking). This is caused by the various materials expanding and contracting under the in-fluence of temperature in your pellet stove. Noise of this kind does not constitute a warranty claim and do not constitute a warranty claim. The territorial scope of validity of our guarantee covers Austria and Germany. In all other countries, sepa-rate conditions of the importer apply to the respective country. No warranty case occurs if your Austroflamm pellet stove is not located within the territorial scope of vali-dity, which does not change if it is transported or dispatched by Austroflamm.”
3. Requirements: A warranty case shall only then be replaceable if your Austroflamm pellet stove has been operated, maintained, installed and commissioned by a specialist authorized by Austroflamm, all in com-pliance with the user handbook. For the replaceability of the warranty case the start-up log must be recei-ved by Austroflamm within one month at the latest of the initial commissioning. In order to make a claim on the warranty, repairs to your pellet stove insert must only be carried out by a service engineer authori-zed by Austroflamm. The warranty claim is asserted with the invoice and serial number with the Austroflamm specialist dealer via whom the purchase was made. An unjustified warranty claim will be charged back to you. Servicing falls due after a number of hours specific to the appliance has been reached, but at least 1x an-nually in order to GUARANTEE THE WARRANTY!
4. Guarantee: This guarantee does not affect your statutory warranty rights towards us. Should your Austro-flamm pellet stove already be defective at the point of handover, you can always connect us within the framework of the statutory warrant regardless of whether there is a warranty claim or the guarantee is clai-med.
