Installation and operating instructions
! Important manufacturer’s instructions!
Please observe the following instructions:
Quality of wood pellets:
Depending on the manufacturer there are light, dark, shorter and longer pellets. And the quality of one delivery may
differ from another even from the same supplier. The standards for wood pellets are becoming more and more strict
but wood is wood and has its own characteristics regarding ash and clinker.
Your HAAS+SOHN stove
Cleaning requirements:
As soon as you find ash and clinker deposits in the cold combustion pot, it must be cleaned. See operating
instructions! If this is not done, there will be more and more clinker. Then the device will no longer be able to ignite
properly. Pellets may pile up in the combustion pot. In extreme cases, this can reach all the way back to the pellet
chute. Backfire in the pellet container and smouldering in the pellet tank might possibly result. This will destroy
your device and is not covered by the guarantee.
For maximum working life:
• Arrange for commissioning by your trained stove supplier.
• Observe the daily check as described and more frequently if you have received new pellet deliveries or when
the device is brought back into use after the summer.
• Carefully read through all the operating instructions and retain them.

Congratulations! You are the owner of a HAAS + SOHN
pellet stove, a quality product. Please read through
these instructions carefully. They will tell you all about
the functions and operation of this stove, which will
increase the utility of this device and extend its working
life. What is more, with the correct heating you can save
fuel and protect the environment.
We can only give a guarantee on our products if you
observe the following instructions in these installation
and operating instructions. In addition, the stove must be
correctly installed so as to prevent possible accidents.
Look after these instructions well, then you will be able
to familiarise yourself with the correct operation of your
stove at the start of every heating period.
Note:
The installation and operating instructions given in this
manual may differ entirely or in part from public authority
instructions. In that event, the public authority
instructions always apply! The drawings in these
instructions are not to scale and serve only as
illustrations.
1. Description
Pellet stoves are particularly suitable for the constant
heating of residential and work rooms. The
HAAS+SOHN pellet stove is set up to operate in fully
automatic mode, with a choice of 2 operating modes
(“Heating” and “Auto” with a weekly programme).
Depending on the room temperature and on the model,
a volume of fuel for a maximum of 30 hours of constant
operation may be stored in the built-in storage container.
The fuel is fed automatically from the pellet tank to the
grate via a screw conveyor, with the quantity of fuel
automatically being adjusted to the relevant heat output.
The internal control unit regulates the ignition phase, the
heating phase and the cooling down phase, thereby
guaranteeing safe operation of the pellet stove. The
operator console, which consists of a display and four
function keys, is built into the pellet tank cover.
On the display’s information screen the operator can
read the operating status that the stove is currently in,
this being displayed as text. Any error messages are
shown on the display as text complete with the date and
time.
The heating of the air in the room and the creation of
comfortable living conditions is mainly achieved by
convection. This allows you to quickly warm up even
cold
rooms that have been unheated for a lengthy period.
The cooler air of the room enters the stove at the bottom
of the cladding, is heated and flows out again at the top
in the area of the slats. The proportion of radiant heat is
given off by radiation in the area of the viewing window
of the combustion chamber door and from the stove’s
metal surfaces.
2. General instructions, safety instructions
• Before commissioning the pellet stove read the
entire installation and operating instructions through
thoroughly.
• Only permitted handling gear with sufficient
loadbearing capacity may be used for moving your
device.
• Your heating device is not suitable for use as a
ladder or mounting frame.
• For the installation of your stove, the fire protection
authority’s regulations and the local building
regulations in force at the installation site are to be
observed and you should also discuss this with the
district heating inspector. He will also check that the
connection of the device to the fireplace is carried
out correctly.
• All the checks required by law have been performed
on your stove. The mandatory indices regarding
technical combustion efficiency and flue gas
emissions are observed.
• The pellet stove may be connected to a multiple-use
chimney provided that the chimney dimensions
permit this according to DIN EN 13384-1 or DIN EN
13384-2. The supply pressure must be at least 6
Pa and should be 15 Pa as a maximum.
•
L The combustion chamber door may be opened
only
for cleaning and maintenance during operating
status “Off”. Otherwise it is to be kept closed – even
when the stove is not operating in order to avoid
affecting other heating appliances and the
associated risks.
• An adequate supply of fresh air must be guaranteed
to the room where the stove is installed. However,
the pellet stove offers you the option of a direct
connection to the outside air via a suitable air duct.
So operation independent of the air in the room is
possible. (See Section 3 “Installation of the pellet
stove and connection to the chimney”).
•
L Attention! The pellet stove may not be set
up to be operated jointly with the home’s air
conditioning and ventilation units.
4
• The chimney (fireplace or flue) must be made of
stainless steel or ceramics (glazed internally) and
suitable for wet operation so that it cannot rot.
• The pellet stove cannot be connected to the mains
electricity until it has been correctly connected to the
fireplace.
• The pellet stove may not be installed in the open
air!
•
L Attention! The mains cable plug must remain
freely accessible after installation.
• The pellet stove may only be operated with standard
wood pellets (6 mm diameter). (See Section 7.1
“Fuel”).
• The protective grille located in the pellet container
must not be removed.
•
L Attention! The Pelletto stove may only be
operated with the tank cover closed.
• Placing non-heat-resistant materials or objects on
the stove or within the specified minimum distances
is forbidden. Here please note in particular that
during “Standby” operating status, the stove may
unexpectedly and unintentionally start heating when
the room temperature falls below the desired
temperature.
• Never use liquid fuels to ignite the pellet stove or to
revive existing embers.
• With the burning up of fuels, heat energy is
released, leading to strong heating of the heating
device’s surfaces (e.g. doors, door and control
handles, viewing window panels, side walls, front
wall, flue tubes). Touching these parts without
suitable heat protection gloves or a tool is to be
avoided!
• The device ignites by itself in “Standby” mode.
Because of the heat generated on the panel, make
sure that no-one who is unfamiliar with the operation
of the pellet stove is unsupervised in the room where
it is installed.
• Bring these risks to your children’s and guests
attention!
• In particular, any cleaning staff should be informed
and instructed regarding the possible unexpected
heating up of the stove.
• Placing non-heat-resistant objects on or near the
heating device (even when it is cold, since it can
ignite again by itself) is forbidden!
• Do not lay any laundry on the stove to dry!
• Clotheshorses for drying clothes and the like must
be positioned at sufficient distance from the heating
device – fire risk!
• When operating your heating device, it is forbidden
to work with highly flammable or explosive
substances in the same room or an adjacent one!
3. Installation of the pellet stove and connection to
the chimney
The packaging on your new pellet stove gives it optimum
protection against damage. Nevertheless, damage may
have occurred to the stove or to accessories in transit.
Please therefore check your stove after unpacking for
damage and completeness! Report any defects or
anything missing to your specialist stove dealer without
delay!
Remark: Combustion chamber cladding that is loose or
has come off its fastenings and the like are not defects.
(See Section 7.2. “Commissioning your pellet stove”).
The packaging on your stove is by and large
environmentally neutral. The timber packaging is not
untreated. The timber, the cardboard and the films can
be taken without problems to your local recycling centre.
For the correct operation of your pellet stove it is
important that it stands horizontally
.
The room temperature sensor that is located on the back
wall has a length of about 1.5 m and should be
positioned hanging free at the back.

Floor protection
The floor is to be protected from the radiant heat from
the area of the viewing window (combustion chamber).
In addition, for practical reasons associated with
cleaning it is recommended that you install your pellet
stove on a fireproof base that extends beyond the device
at the back and on the sides by at least 5 cm and at the
front by at least 50 cm. We have floor protection plates
(underlay plates or U plates) in our range of accessories.
If required, you may order them from your specialist
stove dealer. As an alternative, a tile or stone floor is of
course very suitable.
Safety gaps (minimum gaps):
During installation of the stove it is absolutely essential
to observe the official fire protection regulations. Ask
your district heating inspector about this.
The following must be maintained as the minimum
distances from flammable or temperature-sensitive
materials (e.g. furniture, wallpaper, wooden cladding)
and from loadbearing walls. (See drawing):
A 5 cm from the back wall
B 10 cm from the side walls and
C 80 cm in the direction of radiation.
Figure 2: Safety gaps
The chimney (fireplace or flue) must for example be
made of stainless steel or ceramics (glazed internally) so
that it cannot rot. This is necessary because of the low
temperature of flue gases from your pellet stove.
Standard trade flue tubes may be used for the
connection to the fireplace. Approved Flex steel flues
are also suitable.
Since excess pressure may build up at the smoke outlet
because of the way that the pellet stove works with an
induced draught fan, all fume outlet pipes as far as the
intake to the fireplace must be gas-tight. It is also
essential to ensure that the flue tube does not stick out
into the open cross-section of the chimney. The use of
wall lagging is recommended for the insertion into the
chimney. (See Figure 3).
With longer flue gas pipework, horizontal sections and
constrictions must be avoided and specially insulated
flue tubes should be used. Pipework rising in the
direction of the chimney is recommended.
Figure 3: Chimney connection
1 = Wall lagging
2 = Gas-tight pipework
3 = Underlay plate
External air intake:
In airtight buildings, whilst the pellet stove is operating, a
reduction in the oxygen level in the room where the
stove is installed may occur, so adequate ventilation
must be ensured. For this the pellet stove offers you the
option of operating independently of the air in the room.
To do this, connect the air intake elbow located on the
back (diameter: 50 mm) to a hose or a similar suitable
air duct. The end of the air duct must be located in the
open air or in a well-ventilated room within the building.
When installing the pellet stove in combination with
controlled residential room ventilation, the end of the air
intake duct must not be connected to the ventilation
system in an adjacent room with the air connection
system. To ensure sufficient volume of air intake, the
pipe should not be longer than about 3 m and not have
too many bends. This pipe should have a
6
minimum diameter of 5 cm. (The bigger, the better). If
the pipe goes to the open air, it must end with a
downward 90° bend or with wind protection. (See Figure
4).
Figure 4: Wind protection of the air intake pipe
The following table applies to the sizing of the air intake
pipe:
Diameter of the
intake pipe *
Maximum
length *
Max. number of
90° bends
50 mm 0.5 m 1
70 mm 1 m 1
100 mm 3 m 3
*The figures given apply as appropriate. With a flat duct
or similar, a suitable cross-section is to be chosen.
If the pipes are narrower than these dimensions, it may
be that the volume of combustion air is insufficient. This
will result in heavier buildup of clinker in the grate and
thereby to safety shutdowns.
Connection to the electricity supply:
Connect the stove to the electricity supply with the mains
cable supplied. (See Figure 1).
4. The pellet stove’s functional characteristics
Your pellet stove is designed to operate in such a way
as to maintain a constant comfortable room temperature.
The generation of heat in the stove is therefore
automatically controlled by the desired room
temperature (target temperature) set by the operator.
Depending on the difference between the target
temperature and the current room temperature (actual
temperature) the control unit selects output or “Standby”
mode in a modular fashion. So the pellet stove
guarantees the best possible adjustment of
the combustion behaviour of the pellet stove for the
situation in the room where it is installed without
constant manual corrective measures.
5. The pellet stove’s operating statuses:
The operation of the pellet stove is characterised by 8
operating statuses:
The ignition phase begins if the current room
temperature falls below the set target temperature by
1ºC and the stove has cooled down to a temperature of
below 80C°.
5.1. Ignition phase
In the “Ignition phase” the grate is filled with a precisely
defined quantity of fuel and this quantity of fuel is ignited
with a glow igniter.
The “Ignition phase”, which is divided into 10 zones, is
ended after reaching a precisely defined temperature on
the “flame temperature sensor” and the control unit
switches to “Heating Mode” operating status.
The duration of the “Ignition phase” may vary but it is
restricted to a maximum length of about 20 minutes.
If during these 20 minutes no flame is formed or the
required temperature is not reached at the “flame
temperature sensor – flue gas”, a safety shutdown is
initiated.
Here the rotation speed of the induced draught fan is
constantly measured and checked by means of the
rotation speed feedback.
5.2. Heating mode
After successful completion of the “Ignition phase”, the
stove automatically switches to “Heating mode”
operating status.
In “Heating mode” operating status, the stove’s heat
output is adjusted in modular fashion on the basis of the
room temperature or the difference between the actual
room temperature and the target room temperature.
If there is a great difference between the target room
temperature and the actual room temperature, then the
stove will operate with greater heat output (maximum 8
kW).
The closer the actual room temperature comes to the
target room temperature, the more the heat output of the
stove is reduced (minimum heat output = 2.5 kW).
Depending on the required heat output, the relevant
quantity of fuel will be supplied at a regular rate via the
pellet chute to the grate by means of the screw
conveyor.
During the “Heating mode” operating status, the flame or
combustion chamber temperature is measured just
above the flame by means of a special thermosensor
whose signals are processed in the control unit and are
the basis
7
for the relationship of the “energy level in the grate” and
the combustion air volume taken in, which ensures “ideal
combustion” and a high level of efficiency.
During the “Heating mode” operating status, the rotation
speed of the induced draught fan is monitored by means
of rotation speed feedback and constant comparison
between the target and actual rotation speeds.
In the event of a large difference between the actual
rotation speed and the target rotation speed, a safety
shutdown will be initiated and an error message is
shown on the operator console display.
During the “Heating mode” operating status, the
maximum and minimum heat output are each controlled
by safety limits (maximum and minimum flue gas
temperature) i.e. if during the “Heating mode” operating
status the maximum flue gas temperature is exceeded
or if the flue gas temperature falls below the minimum, a
safety shutdown will be initiated.
5.3. Burner test
Every 30 minutes during the “Heating mode” operating
status, a burner test is performed.
The burner test is performed regardless of the heat
output currently being delivered by the stove.
This process takes about 2 minutes.
5.4. Cooling down
If the set target room temperature is reached i.e. the
actual room temperature and the target room
temperature match, then the control unit switches to
“Cooling down” operating status.
The fuel supply is stopped i.e. the screw conveyor that is
located in the screw conveyor tube, stops, the rotation
speed of the induced draught fan is regulated to a
precisely defined rotation speed and the fuel which is
still in the grate is burnt.
The cooling down phase is restricted by timing control
(duration about 15 minutes).
After the end of the “Cooling down” operating status, the
device switches to “Standby” operating status.
5.5. Standby
There is no combustion process going on in this
operating status, all the components, the induced
draught fan and the screw conveyor are stopped, the
ignition is switched off and the device is in a “waiting
position.”
Before the stove can switch back from “Standby”
operating status to the “Ignition phase” operating status,
two ignition conditions must be fulfilled:
1. The room temperature must be at least 1.0ºC
below the set target room temperature.
2. The flue gas temperature measured with the
thermosensor must be lower than 70°C.
It is only when both these ignition conditions have been
fulfilled that the device switches back from “Standby”
operating status to “Ignition phase” operating status.
L Attention!
The device starts by itself in “Standby mode”.
Because of the heat generated on the panel, you
must ensure that there is no-one who is unfamiliar
with the operation of the pellet stove unsupervised
in the room where it is installed.
Placing non-heat-resistant materials or objects on
the stove or within the specified minimum distances
is forbidden.
5.6. Safety shutdown (shutdown)
If a fault occurs, regardless of in which operating status
or which operating mode, a safety shutdown is initiated.
The safety shutdown process is precisely defined.
During the safety shutdown, the components are
switched on or off as follows:
Induced draught fan – ON
Screw conveyor – OFF
Ignition – OFF
The ending of the safety shutdown is temperaturedependent i.e. the “Safety shutdown” operating status is
maintained until the stove has cooled down to a flue gas
temperature of below 80°C.
Once the safety shutdown is ended, the control unit
switches to the “Fault” operating status.
5.7. Faults
The stove can no longer be automatically started up.
The operator can see the fault on the display.
Once the fault has been properly corrected and the error
message on the operator console has been cleared, the
stove may be started up again.
8
5.8. Switching off – operating status OFF
Procedure:
Press the left key on the operator console until the
information screen appears.
Press the right key (Menu), then move the cursor to
Operating Mode with the two middle keys – press the
right key (Select) – move the cursor to “OFF” operating
mode with the two middle keys – press the right key
(Save).
The stove initiates the Cooling down operating status
and can no longer switch to Heating mode by itself, even
if the room temperature falls below the set room
temperature.
During OFF operating status, the operator console and
parts of the control system continue to be supplied with
power. (About 9 Watts per hour).
5.9. Power cut
The control unit has a backup battery so that the data
are retained during a power cut.
A distinction is made between a short power cut and a
long power cut.
Short power cut – duration of the power cut shorter than
30 seconds:
Once the electricity supply has been restored, the stove
continues its operation from where it was before the
power cut.
Long power cut – duration of the power cut longer than
30 seconds:
Once the electricity supply is restored, the stove
switches to Safety shutdown operating status.
A small amount of flue gas may escape during a power
cut.
5.10. Overheating
If the maximum permitted flue gas temperature is
exceeded, a safety shutdown is initiated and the
following error message is shown on the display:
“Shutdown flue gas temperature in Heating mode too
high”.
The stove cannot restart its heating mode until the error
message has been cleared on the operator console and
the desired operating mode has been reset.
5.11. Low temperature shutdown
If during the Heating mode operating status the stove
cools down below a minimum temperature, a safety
shutdown is initiated and the following error message is
shown on the display:
“Shutdown flue gas temperature heating mode too low”
The stove cannot restart its heating mode until the error
message has been cleared on the operator console and
the desired operating mode has been reset.
6. Description of operator console keys

7. Operating the pellet stove
The pellet stove may only be heated by adults. Make
sure that children are never left alone with the pellet
stove. (Do not leave the pellet stove unsupervised for a
long period). The pellet stove may only be used in
accordance with these operating instructions.
Please observe the safety instructions set out in Section
2.
7.1. Fuel
The pellet stove may only be operated with “pellet” fuel.
With this fuel you have chosen CO
2
-neutral heating for
your home.
Pellets are made from wood waste from sawmills and
planing works and from wood collected from forestry
businesses. These raw materials are therefore of 100%
natural origin and are ground, dried and pressed into
“pellet” fuel without the addition of binding agents.
This fuel is standardised (e.g. DIN 5173, Ö-Norm [Eco
standard] M 7135, EN 14961-2).

L Important: Your HAAS+SOHN Pelletto pellet
stove may only be operated with standardised wood
pellets with a 6 mm diameter.
You can identify good quality wood pellets by eye by:
smooth, shiny surface, uniform length, little dust. Wood
pellets of lower quality are characterised by: Lengthwise
and crosswise cracks, a high proportion of dust, different
lengths. Precise quality features may however only be
identified with suitable technical analysis equipment.
A simple quality test: Put a few wood pellets in a glass of
water:
Good quality: Pellets sink
Lower quality: Pellets float.
The use of lower-quality or unauthorised fuel adversely
affects the operation of your pellet stove and may in
addition lead to the lapse of the guarantee and the
associated product liability. Unauthorised fuels include
woodchips, straw and maize. Burning wood pellets of
poor quality leads to shortening of the cleaning intervals
and to increased fuel consumption, so the pellet tank
has to be filled more frequently.
Wood pellets are packed in plastic or paper sacks. To
ensure problem-free combustion of the wood pellets it is
necessary to dry the fuel as much as possible and to
transport and store it free from dirt. On contact with
moisture, pellets swell considerably.
When filling the storage container with wood pellets,
make sure that the pellet sacks do not come into contact
with the hot surfaces of the stove.
Two kilograms of wood pellets have about the same
energy content as a litre of “extra light heating oil.” In
terms of volume, 3 m
3
of wood pellets are equivalent to
about 1,000 litres of heating oil. Variations in heat output
by the pellet stove are caused not only by the quality of
the pellets but also by the raw material of the wood (type
of wood).
7.2. Commissioning your pellet stove
The materials making up your pellet stove must
gradually get used to the heat generation. By careful
warming up you avoid cracks in the combustion
chamber plates, damage to the paintwork and warping
of materials. So do not set the target temperature too
high on the control unit (about 1.5°C to 2°C higher than
the current room temperature).
• Before commissioning, remove any stickers and any
accessories from the ash pan and the combustion
chamber. This also applies to any
transportation/handling securing materials.
• Check that the combustion chamber cladding is
attached to its fastenings. (This might have slipped
out
of its position as a result of the transportation or
installation of the stove).
• Check that the combustion pot fits perfectly in its
frame.
• Close the combustion chamber door.
• Fill the storage container with standard wood pellets
(Ø 6 mm).
• Insert the mains cable.
• Set the On-Off toggle switch to “1”.
• Once the toggle switch has been set to ON, the
control unit commences initialisation. This process
takes a few seconds.
• After initialisation, the Information screen appears –
press the right key (Menu) – move cursor to
Operating mode – press the right key (Select) –
select the desired operating mode with the cursor –
press the right key (Save).
Tip!!
Only when commissioning, place about 30
pellets in the burner. This will speed up the
ignition process.
General:
If the ignition phase could not be successfully
run i.e. no flame generation or the required
temperature could not be reached at the flue
gas thermosensor, then a safety shutdown is
initiated and an error message generated
(“Ignition phase target temp. flue gas not reached –
check burner – date and time”).
Correcting the fault:
Once the stove has cooled down, empty the burner and,
if necessary, clean it. Take care! There may still be
residual embers in the ash! Then press the left key on
the operator console repeatedly until the error message
appears – then press the right key of the operator
console (Clear) – now the Info screen appears – press
the right key (Menu) – move the cursor to Operating
mode and press the right key (Select) – the screen in
which the operating mode may be selected appears –
select desired operating mode with the cursor and press
the right key (Save). The stove begins the ignition
phase.
Note: Any smoke generation caused by further drying of
the paint stops after a short while. Please properly
ventilate the room where the stove is installed. However,
the paint does not contain any toxic vapours.
7.3. Selecting the operating mode
The control unit allows easy selection of operating mode
from the “Heating” and “Auto” weekly programme
modes.
