General warn and safety
instructions
Observance of the general introductory warning
information is vital.
xRead the complete manual carefully prior to
commissioning of the stove.
xDo only use approved transport aids with
adequate lift capacity for transport of your stove.
xThe combustion of fuel releases thermal energy
that may cause strong heating of the surface of
the stove, the doors, the door and operation
handles, the door glasses, the flue tubes and
possibly the front panel of the stove. These parts
may not be touched without applicable protection
clothes or devices, such as thermal protection
gloves or operation devices (operation handle).
xInstruct your children on such special risks and
keep them away from the stove during heating
operation.
xDo not place not fire-resistant items on the stove
or near to it.
xDo not place wet clothes on the stove for drying.
xClothes drier or similar must be positioned in a
safe distance to the stove – FIRE RISK!
xDo not process inflammable and explosive
materials in the same or in neighbouring rooms
while your stove is operated.
xThe owner is responsible for the cleanness of
the stove at all times.
xThe manufacturer’s warranty is valid only if the
initial commissioning with system acceptance
was performed by a service partner certified by
Rüegg, and a copy of the “report of system
acceptance” has been sent to Rüegg. The
service partners are in possession of a
certificated issued by Rüegg authorizing them for
service and repairing works on your pellet stove.
The packaging
The packaging of your new pellet stove offers optimal
protection against damages. However, damages to
stove and accessories might be caused during
transport.
Please check you pellet stove carefully for damages
and completeness after delivery! Any defects must be
notified immediately to your stove dealer! The
packaging is largely environmentally friendly.
The box and the film (PE) may be disposed off via the
communal waste collection points for recycling.

Please ask your pellet stove dealer for certified fuel
and a list of controlled fuel producers. The use of low-
quality or inadmissible pellet fuel will impair the
functioning of your pellet stove and may result in the
loss of your warranty, the guaranty and the connected
product liability.
Observe waste incineration legislation!
Storage of pellets
To ensure trouble-free pellet combustion pellets
should be stored in a dry and clean place.
Technology
The state of the art of your new pellet stove is
ensured by years of laboratory and practice based
test series.
The practical benefits of your pellet stove are
convincing:
Ease of use – operational safety
Electronic monitoring combined with a combustion
temperature control monitors and controls the
interplay of flue fan, conveyor screw and temperature.
This control system ensures an optimal combustion
and operation condition. The operating effort is
reduced to the necessary minimum – this helps to
prevent faulty operation and ensures optimal
operation at the same time.
Higest efficiency – Lowest
emissions
A large heat exchanger surface combined with an
optimal combustion air control allows excellent fuel
efficiency.
Accurate dosing of pellets in an optimized high-quality
grey cast burner pot allows a nearly perfect
combustion with excellent emission specifications –
this is guaranteed for every operating phase.
TAOS green in favour of the
environment
Wood pellets as a fuel are CO2neutral and
consequently environmentally friendly and
sustainable. In addition, all Rüegg stoves can be fitted
with a Fine particulate collector (option). This
makes them to the cleanest stoves in general with the
“Zumik®on“ fine particulate collector allowing to
reduce the already low fine particulate rate by around
another 90%!
The TAOS pellet stove is optimally suited to be
refitted with such fine particulate collector by your
special dealer. Simply ask for the green kit.
Rüegg is the leading manufacturer for fine particulate
collectors for firewood and pellets furnaces. For
further information check our homepage
(www.zumikron.ch)

General instructions
For levelling of the stove the machine mounts under
the device can be adjusted in height and locked
(counter nut SW13).
The function of the smoke venting system is based on
negative pressure in the combustion chamber and a
minor superpressure on the flue gas outlet. Therefore
correct and airtight installation of the flue gas
connection must be ensured.
The device must be connected to a chimney approved
for solid fuels. The diameter of the chimney must be
at least 120mm. In case of a chimney with a diameter
exceeding 200mm and a certain height installation of
a draft reduction may be required. This is why you
should consult a chimney expert prior to installation of
the stove. In cooperation with the stove fitter who may
adjust the parameters of the control, the chimney
expert can ensure the proper connection of the stove
to the chimney.
IMPORTANT!
Only use heat resistant sealing materials and
applicable sealing bands, heat resistant silicone and
mineral wool.
We recommend to charge an authorized expert with
the assembly (and/or control and acceptance for self
installation)!
Also ensure that the flue tube does no extend into the
free cross section of the chimney.
CAUTION!
xPlease observe the applicable regional building
regulations. Ask your chimney sweep for advice.
xFlue pipes should not be too long.
xAvoid too many changes of direction for the flue
gas flow to the chimney. (e.g. too many corners
and bends)
In case of self installation the installation must be
accepted by a partner certified by Rüegg in order for
the warranty to be valid. The costs for the initial
commissioning with customer introduction and setting
of the parameters by the charged service partner are
in most cases charged separately. Ask your service
partner for a service subscription.
Electric connection
The stove is supplied with an approximately 2.5m long
connection cable with a Euro plug. Connect the cable
to a 220/230V, 50Hz power connection. For
installations in Switzerland replace the Euro plug by
the supplied plug. The average electric power
consumption during operation is approximately 100W.
During the automatic ignition process (duration
approximately 10 minutes) approximately 350W. The
connection cable must be laid in a way that any
contact with hot or sharp-edged external surfaces of
the stove is avoided.
Combustion air
Every combustion procedure requires oxygen and/or
air. For individual stoves this combustion air is
generally taken from the living area. The air taken
from the living area must be reintroduced. In modern
houses with very tight fitting windows and doors the
amount of air flowing back may not be enough. This
situation may also become problematic due to
additional ventilation in the house (e.g. in the kitchen
or toilet).
External air supply
This external air supply means, that this air is supplied
to the stoves adaption connector by means of a tube
or duct, directly from outside or from another room
(e.g. cellar or boiler room) This connector does not
lead directly into the combustion chamber, but to the
inside of the pellet stove. This has the advantage that
the stove can take exactly the amount of air it needs,
and that this air is already preheated by passing
through the room. If the stove is not used, there
should be a possibility to close this air supply as close
to the facade as possible, to prevent cold damp air to
flow into the duct and unnecessarily cool down the
room or at temperatures well underneath 0° C to
provoke condensation problems. Therefore it is
important to insulate the ducts and make sure that
eventual condensation fluid can run off freely in the
right direction.

7
Connecting the Rüegg room sensor
Disconnect stove from the power supply before
connecting the multi-pin plug. Subsequently carefully
tighten multi-pin plug on board using screws.
The white plastic casing is designed for wall
mounting. For this purpose holes for screws are
provided in the inside of the casing.
After mounting to the wall lock casing cover (min.
approximately. 2m distance to the stove).
Chimney
Only a correct calculation of the chimney according to
e.g. DIN 4705 guarantees a correct dimensioned
chimney. Especially in rather air tight houses (low
energy houses), the installation of a draft reducer
afterward s is almost impossible, because there may
be no direct contact between the outside air and the
room air. The chimney connection has to be executed
according to the national prescriptions that are in
force at that time.
Floor protection
Floor space: Due to its weight the firing installation
must be set up on a suitable, fire-resistant surface.
For minimum distances from the outer edges of the
stove to the base plate edges refer to the drawing.
Note: The indicated safety distances may differ from
the applicable legal regulations. Observe the
applicable local regulations for your country.
The glass or steel plate ensures protection of the floor
from the heat of the stove and from embers that might
fall down when the combustion chamber door is
opened.
Especially for flammable floors (wood, carpet, etc.) a
floor protection is required!
Safety distances
For flammable objects:
(Measured from the outside of the stove):
-20 cm from the back and the sides
-80 cm from the front
For non flammable objects:
(Measured from the outside of the stove):
- 10 cm from the back and the sides
- 40 cm from the front
Note: If the flue tube is lead vertically behind the stove
before entering the chimney, the safety distance from
the outside of the tube to the wall or to objects must
be respected.

Important information on how to use the menu (illustrations)
The illustrations below always depart from the display field in the oval frame. The illustrations in these operating
instructions show the display screens and the buttons that have to be pressed in order to access the next screen (in
the direction of the arrow).
In the main menu tree illustration (page 11) you will find a number in a circle below or next to some menu items. On
the following pages the same number in a circle will be shown to indicate that the instruction for the corresponding
menu item is continued.
In order to benefit from the various options offered by the pellet stove in advanced mode you should take your time
to read the operating instructions thoroughly.
Changing to advanced operating mode
The advanced operating mode is accessed by pressing and holding the MENU button for at least 5 seconds while
the stove is switched off (EASY OFF) (see illustration). The display will change to HEAT OFF or to the function mode
display which has been selected when the advanced operating mode was closed the last time (variable mode
display, see next section).
The advanced operating mode offers three alternatives on how to operate the stove:
HEAT mode: (manual operation) operation by selecting the heating performance. (page12 “heating in the
HEAT mode“)
ROOM mode: (thermostat controlled operation) operation by selecting the required room temperature.
(page12 “heating in ROOM mode“)
AUTO mode: (automatic operation) programming of the heating times and temperature. (page 13 “heating
in the AUTO mode“)
To return to simple operating mode press the MENU button for 5 seconds.
Variable mode display
When selecting the advanced operating mode the display will not show EASY but the name of the current selected
mode. This means that the variable mode display will show HEAT,ROOM or AUTO, according to the selected
function (see illustration main menu tree next page). In addition, the display will show the current activity of the pellet
stove: It will show IGNIT for ignition, START for the start-up phase, STANDBY for the stand-by phase or STOP if the
required temperature has been reached in AUTO or ROOM mode.
The particularity of the variable mode display is the varying information shown on the display on the same position of
the main menu tree (illustration on the following page). This means that the varying screens in the variable mode
display can be the departing point for the main menu tree.

stop after a few minutes. After re-establishing the
contact the device will restart.
(see „EXT“ page 15/16)
Fan stop delay for all error messages
The fan stop delay occurs for all error situations and
at least until the flame sensor identifies a temperature
exceeding 100°C.
System stop in case of flame sensor failure
In the event of a failure of the flame sensor in the
combustion chamber the pellet feeding will be
stopped and the fan will run for another 10 minutes.
Power failure during operation
After a power failure the flame temperature will be
checked. If the temperature exceeds 300°C the
device will not attempt to restart but continue the
normal operation.
Below 300°C: Normal start process with ignition
cartridge. The stove must be started manually via the
operation panel.
Power failure during ignition process
The ignition process will be carried out by use of the
ignition cartridge after reestablishment of the power
supply.
Electric ignition
The pellet stove is equipped with an electric ignition
system. The electric ignition is operated when the
stove start-up program is initiated. Ignition duty cycle:
approximately 10 min.
IMPORTANT!
If the electric ignition is faulty please request a service
or repair visit.
Firing- up without electric ignition:
In case of the electric ignition being faulty proceed as
follows:
1.Check if the pellet container is filled and the
combustion chamber is clean and free from
impurities.
2.Place approved firelighters in the fire pan and cover
with a small handful of pellets.
CAUTION!
Do not use flammable liquids (e.g. burning spirit) for
firing-up the stove!
3.Light the firelighter in the fire pan using a match and
close the stove door carefully. Press the I/O button
to start the stove.
Pellet consumption
The pellet consumption depends on the heating
output. The pellet stove can be used permanently
without any concerns and free from risk; however, we
recommend that you reduce the heating output
overnight and when the room is left for a longer
period.
In case of any inquiries regarding the pellets please
contact your certified dealer.
(Further information on the pellets: page 4)

Fuel feed
IMPORTANT! Avoid contact of pellet bag with the hot
stove during fuel feeding!
Remove any pellets that have not been put in the
storage container immediately!
To prevent the fire from going out due to lack of fuel,
we recommend that an adequate filling level is
maintained in the storage container. A 15kg bag of
pellets can be fed to your pellet stove when the filling
of the pellet container is less than 2kg. Check the
filling level regularly. The container lid should,
however, always be kept closed unless the container
is being filled.
Prior to refilling pellets use a vacuum cleaner to clear
the pellet container from wood dust.
Use the supplied glove when filling the storage
container.

Faults – causes - measures
PROBLEM/ERROR
DISPLAY FAULT DESCRIPTION
MEASURES
(Start with first step. If not successful, perform with next
step)
“NOT IGNITED“ Fire ignition prevented due to certain conditions.
- Check pellet supply and refill pellets, if required (for first start
add some pellets manually to the fire pan)
- Restart stove
- Check supply air
- Have ignition cartridge checked (If ignition cartridge is defect
use match to light pellets until fault is fixed)
“DOOR OPEN“ Door is not closed or not closed properly. - Close door
- Have door contact switch checked
“STB“ The safety temperature limiter (STB) was activated
due to overheating in the stove.
- Remove all objects that are too close to the stove (see page
4)
- Allow stove to cool down and relock STB in position (page
18)
- Clean all flue gas channels
“NO PELLETS“ The pellet supply to the fire pan stopped or fire
ignition prevented by other conditions.
- Check filling level in pellet container
- Replace pellets with another sort (quality)
- If tank is empty clean container and loosen/refill pellets, if
required
“FAN DEFECT“ The flue fan is faulty/insufficient circulation of flue
gas and/or supply air.
- Unplug device from the main supply for a short while, clean
fan gas channels and restart stove. In case of repeated
occurrence >>
- contact customer service (service partner)
