Please read through these operating instructions carefully. You will be informed about the function and handling of
this stove and you will also save fuel and conserve the environment by heating correctly.
The attached equipment sheet is part of these operating instructions.
1. General information
Please check the appliance for transport damage when unpacking it. In case of defects, please report
these immediately to your stove dealer!
National and European standards, local regulations and those under building law as well as the relevant
state building regulations or fire regulations must be complied with when installing, connecting and putting
the fireplace into operation.
The pellet stove described in these instructions has been tested according to DIN EN14785 and
according to the electrical standard, DIN EN 60335-2-102.
2. General safety information
The combustion of fuels releases heat energy, which leads to the surfaces of the heating appliance (e.g.
doors, inspection window panes, side walls, front wall, flue tube) heating up significantly.
The appliance starts independently in "Standby mode". Due to the build-up of heat on the window pane,
care should be taken that no unsupervised persons, who do not know how to operate the pellet stove, are
in the installation room.
Air extraction equipment such as ventilation systems, extractor hoods, vented tumble dryers etc. or other
fireplaces must not have a disruptive influence on the air supply for the stove.
During operation, the combustion air opening provided must not be closed, throttled, constricted, covered
or shut off.
On stoves with an outdoor air connection, the opening must not be shut or closed during operation.
Make children aware of these dangers and keep them away from the fireplace when it is in heating mode.
The combustion chamber door must only be opened for cleaning and maintenance purposes when in
“Off” mode. Otherwise this should always be kept closed.
The pellet stove may only be connected to the mains after being properly connected to the fireplace.
The protective grille in the pellet container must not be removed.
The pellet stove must only be operated when the tank cap is closed.
Never use liquid fuels to ignite the pellet stove or to revive existing embers.
Do not place any laundry items on the stove to dry!
When operating your heating appliance, it is forbidden to work with highly combustible and explosive
materials in the same or adjoining rooms!
The stove must not be set up to be operated jointly with the home’s air conditioning and ventilation units.
Exceptions:
RLU certified appliances can also be operated with extractor hoods, vented tumble dryers and air conditioning and
ventilation units if the stove has also been connected to a balanced flue.
3. Electrical connection
The stove is operated with a mains voltage of 230V 50Hz. The average power consumption is 50-60
Watts. During the ignition phase, the power consumption can increase to 400 Watts.
Only use the original mains cable supplied with the appliance
The socket must be easily accessible.
4. Chimney
The chimney should be made e.g. of stainless steel or ceramic (glazed inside) so that it cannot become
contaminated from soot and damp. This is necessary due to the low flue gas temperature of your pellet stove.
Please observe the national regulations.

4
4.1. Weather conditions
For the safe operation of the fireplace, it must be ensured that the chimney is able to build up the necessary flue draft.
Particular attention needs to be paid to this during the transition period (e.g. autumn and spring) or during poor
weather conditions (e.g. strong wind, fog etc.).
4.2. Chimney flue draft at rated heat output of the stove
min. flue draft
6 Pa
if the minimum flue draft is not reached, then it is not possible to
operate the fireplace properly and it will lead to increased
contamination of the burner and inspection window.
max. flue draft
15 Pa
if the maximum permitted flue draft is exceeded, this leads to
increased fuel consumption.
4.3. Connection to the chimney
For the connection to the chimney, gas-tight flue tubes should be used. Approved flex steel tubes
are also suitable. Please observe the national regulations.
The flue tube must be securely fitted on the flue gas spigot.
The flue gas tube must not be installed with a drop to the chimney.
It is also essential to ensure that the flue tube does not stick out into the open cross-section of the
chimney, which would interfere with the flue gases rising and prevent the optimal cleaning of the
chimney.
The use of wall lagging is recommended for the insertion into the chimney (see Figure 3).
Longer horizontal flue gas connections reduce the necessary flue draft.
All openings leading into the same chimney, such as stove and chimney cleaning apertures, must
be closed.
4.3.1. Multiple use
The stove is not approved for multiple use.
5. Installation
5.1. Minimum gaps to flammable components:
When installing the stove, it is essential to observe the official fire protection regulations.
Please observe the national regulations to this effect.
As the minimum distances from flammable or temperature-sensitive materials (e.g. furniture, wallpaper,
wooden cladding) and from load-bearing walls, the specified gaps “at the back”, “on the sides” and in the “direction of
radiation forwards” must be maintained according to the nameplate.
Floor protection:
In case of flammable or temperature-sensitive floor coverings, the
appliance must be placed on a non-flammable base (see drawing).
Recommendation for floor protection:
A30 cm –at the front
B10 cm –at the sides
Cup to the back wall

5
5.2. Combustion air supply
It must be ensured that there is sufficient fresh air at the place of installation.
5.3. Outside air connection
We recommend using the outside air connection for the supply of combustion air in order not to use up the
valuable indoor air when heating.
To do this, connect the air intake elbow located on the back to a hose or a similar, suitable air duct or to a
chimney system designed for this purpose. The diameter of the air duct must be at least the diameter of
the outdoor air connection on the stove.
The end of the air duct must be located outside or in a well ventilated area (basement).
It is not recommended to feed the cold air into the room from outside via a direct duct, as this can lead to the
build-up of condensation.
In order to guarantee a sufficient supply of air, the duct should not be longer than approx. 3 m and not
have too many bends.
If the duct leads outside, it must end with a 90° bend facing down or a wind protection device (see Figure
4).
Figure 4: Wind protection of air supply duct
For operation independent of indoor air with RLU certified appliances, the outside air connection must be
connected.
For the dimensions of the air supply duct:
Air supply duct diameter
Maximum length
Max. number of 90°
bends
50mm
0.5 m

7. Operating the pellet stove
7.1. Suitable fuels
Pellets with 6mm diameter
Identification: DINplus, ÖNorm M 7135, ENplus-A1
7.2. Unsuitable fuels
The use of lower-quality or unauthorised fuel adversely affects the operation of your pellet stove and may lead
to the lapse of the guarantee.
Burning wood pellets of a poor quality leads to cleaning intervals becoming shorter and more fuel being
consumed.
Unauthorised fuels are, for example
wood chips
straw
maize
firewood
etc.

7.3. Using for the first time
7.3.1. General:
Before using for the first time
Remove any stickers.
Remove all accessories from the pellet tank and the
combustion chamber.
Check whether the combustion chamber cladding (see appliance sheet - combustion chamber
replacement part Figure 8a) is attached to its fastenings. This could have slipped out of its position as a
result of the transportation or installation of the stove.
Check that the burner fits perfectly in its mounting.
Close the combustion chamber door.
Fill the storage container with pellets
Plug in mains cable
Tip!!
Only when using for the first time, place approx. 30 pellets in the burner. This speeds up the ignition process.

test laboratories!
In this menu, the partial load / nominal load is tested according to EN 14785
standard.
Procedure:
Use the "Plus" or "Minus" keys to enter the required code.
The code is as follows: 1854
Pressing the "OK" button saves the setting.
The test setting partial load or nominal load is then selected.
Pressing the "OK" button activates the "START" of the respective test setting.
10. Operating statuses:
10.1. Start Zone 1-20 ( Start phase )
The start phase begins if:
the current room temperature falls below the set target temperature by 1°C
the stove is cooled down to a temperature below 70 C°
During the “Start phase”, the burner tray is filled with a precisely defined amount of fuel and this fuel is ignited using
an electric ignition.
The whole “Start phase” can go through up to 20 zones. It finishes after reaching a precisely defined temperature at
the “flame temperature sensor” and the control system puts the stove into “Heating mode”.
The duration of the “Start phase” can therefore vary.
If, during the start phase, no flame generation can be achieved or the required temperature at the “flame temperature
sensor” cannot be reached, a switch-off process is initiated.

10.2. Heating mode
After the positive conclusion of the “Start phase”, the stove automatically switches to “Heating mode”.
In “Heating mode”, the heat output of the stove is adjusted in modular fashion to the room temperature or to the
difference between the ACTUAL and TARGET room temperatures.
If the difference between the ACTUAL and TARGET room temperatures is big, then the stove heats with a bigger
heat output.
The nearer the ACTUAL and TARGET room temperatures get to each other, the more the stove's heat output is
reduced.
10.3. Burner test (burner cleaning)
During the “Heating mode” operating status, an automatic burner cleaning process is carried out at regular time
intervals (e.g. 30 minutes).
This process takes approx. 2 minutes.
10.4. Cooling down
If the set TARGET room temperature is reached or the “ON/OFF” button is pressed, then the operating status
switches to “Cooling down”.
The cooling down phase is restricted by timing control (duration about 15 minutes).
After the end of the “Cooling down” operating status, the appliance switches to “Standby” operating status or “OFF”.
10.5. ECO mode
Eco mode means continuous operation at a low output, if the “ACTUAL room temperature” is higher than the set
“TARGET room temperature” i.e. the stove does not switch off but continues to run on a “smaller flame”.
If the set “TARGET room temperature” is exceeded by more than 2°C in eco mode despite a small flame,
eco mode is automatically switched off and the stove switches to the “Cooling down” operating status.
Eco mode function is automatically deactivated.
If an “ACTUAL room temperature” of 30°C is exceeded in eco mode,
eco mode is automatically switched off and the stove switches to the “Cooling down” operating status.
Eco mode function is automatically deactivated.
10.6. Standby
The stove is in a waiting position
Before the stove can switch from “Standby” back to the “Start zone 1-20” operating status, two start conditions must
be fulfilled:
The ACTUAL room temperature must be at least 1.0 °C below the set TARGET room temperature
The flue gas temperature measured with the flue gas thermosensor must be less than 70 °C
10.7. Switch-off
If a fault occurs, then a switch-off is initiated. The components are switched on or off as follows:
Induced draught fan –ON
Screw conveyor –OFF
Ignition –OFF
10.8. Cooling down
The end of the switch-off process depends on time and temperature.

A safety temperature limiter (STL) automatically switches the stove off if it overheats. The error F001 is shown on the
console display under operating status.
12. Power cut
The control unit has a backup battery so that data is retained during a power cut.
A distinction is made between a short power cut and a long power cut.
Short power cut:
The short cut lasts for less than about 30 seconds:
Once the electricity supply has been restored, the stove continues its operation.
Long power cut:
The short cut lasts for more than about 30 seconds:
Once the electricity supply is restored, the stove switches to the Switch-off operating status and
subsequently to “OFF”.
13. Cleaning and maintenance work (see Appliance sheet 4).
14. Faults, causes, correction
You can correct simple operating faults yourself with the following guide. For further information please consult your
specialist dealer.
If a fault occurs, you will be shown this on the display.
In the event of a fault, do not pull the mains plug out straight away, so that the internal safety functions can
continue to operate fully. Only in this way can the flue gases present be extracted via the chimney using the
fan. Only pull out the mains plug before starting work on the cold appliance.

16. Warranty
HAAS + SOHN gives the purchaser a warranty within the context of the statutory regulations. The two-year guarantee
period commences on the date of the actual handover.
The receipt is to be presented as evidence.
If a defect occurs in your appliance within the warranty period, HAAS + SOHN will correct (repair) this defect in the
shortest possible time or optionally replace the defective item. Cancellation of the contract /a reduction in price is
excluded in so far as this does not conflict with the statutory regulations. Only replacement parts that are expressly
authorised or offered by the manufacturer may be used.
Changes to the item purchased that are connected with normal use (wear to the parts that come into contact with fire
such as combustion chamber cladding, burner, ignition cartridge, combustion recess, grate, paintwork, tension and
deflection plates, sensors, glass ceramics and seals, seals of any kind, handles), invalidate a warranty.
Maintenance or cleaning not performed or performed inadequately, a flue draft that is incorrectly set to the appliance
or is insufficient or too high, improper commissioning, negligence and changes to the appliance, also invalidate a
warranty.
If any constructional change is made to the stove or if it is not used for the intended purpose, any claim
under warranty lapses.
