Der T-SKY eco2 / T-ART eco2 ist mit einer automatischen,
thermostatgesteuerten Zuluftklappe ausgerüstet, die sich
nach dem Holzabbrand automatisch verschließt. Ein zu ra-
sches Auskühlen des Speicherofens wird somit verhindert
und die Wärmeleistung verlängert.
Der T-SKY eco2 / T-ART eco2 ist mit einer selbstschliessenden
Feuerraumtüre ausgerüstet, die sich automatisch verriegelt.
Gleichzeitig erfüllt die Feuerraumtür die Zulassungskriterien
des DIBt für den Einsatz bei raumluftunabhängigem Betrieb
(kontrollierte Wohnraumlüftung).
Der Abbrand des Brennholzes im
T-SKY eco2 / T-ART eco2
erfolgt von oben nach unten. Die Top-Down Verbrennung ge-
währleistet niedrigste Emissionswerte. Durch den sauberen
Abbrand bleibt nur wenig Asche zurück. Mit einer Holzladung
erleben Sie ein Flammenspiel von ca. 2 Stunden.
Mit dem Konvektionsmodul des T-SKY
eco2
DUO erhalten Sie
im „Handumdrehen“ den Zusatznutzen einer höheren Direkt-
wärmeabgabe in der Anheiz- und Abbrandphase. Wählen Sie
bei Bedarf zwischen Konvektionsunterstützung und purer
Strahlungswärme.
Als Neuheit besitzen alle T-SKY eco2 / T-ART eco2-Modelle
einen manuellen Anheizschieber. Die individuell bedienba-
re Starthilfe zum Anheizen unterstützt bei schwierigen Zug-
oder Witterungsbedingungen den Anheizvorgang.

Le T-SKY eco2 / T-ART eco2 est équipé d’une vanne d’air
d’amenée commandée par thermostat qui se ferme auto-
matiquement après la combustion du bois. Un refroidisse-
ment trop rapide du poêle à accumulation est ainsi empê-
ché et la puissance calorifique est accrue
Le T-SKY eco
2
/ T-ART eco2
est équipé d’une porte de foyer à fer-
meture automatique qui se verrouille automatiquement. Cette
porte répond en même temps aux critères d’homologation du
DIBt pour l’utilisation en fonctionnement indépendant de l’air
ambiant (ventilation contrôlée de l’espace d’habitation).
La combustion du bois dans le T-SKY eco
2
/ T-ART eco2
se fait
du haut en bas. La combustion du haut en bas garantit les
valeurs d’émissions les plus faibles. Grâce à une combustion
bien propre, il ne reste que peu de cendre. Avec une charge de
bois, le jeu des flammes se poursuit pendant environ 2 heures.
Avec le module de convection du
T-SKY eco2
DUO, vous béné-
ficiez en un „tour de main“ de l’utilité supplémentaire d’une
diffusion directe accrue de chaleur pendant la phase de début
de chauffe et de combustion. Au besoin, choisissez entre l’assis-
tance fournie par la convection et la chaleur rayonnante pure.
La nouveauté : tous les modèles T-SKY eco2 / T-ART eco2
possèdent une manette d’allumage. Cette aide au démar-
rage utilisable manuellement facilite l’allumage en cas de
mauvais tirage ou de conditions météorologiques difficiles.
The T-SKY eco2 / T-ART eco2 is fitted with an automatic, ther-
mostat controlled air supply flap that closes automatically
after the fi ewood has stopped burning. This prevents the
storage heating stove from cooling down too quickly, and
heat is emitted longer.
The T-SKY eco2 / T-ART eco2 is fitted with a self closing firin
chamber door that locks automatically. At the same time the
firing chamber door fulfils the DIBt approval criteria for op-
erations independent of indoor air (controlled living space
ventilation).
In the T-SKY
eco2 / T-ART eco2
, fi ewood burns from top to
bottom. Topdown combustion has the lowest emissions. This
clean mode of combustion leaves only little ash. A single charge
of fi ewood presents flickering flames for about two hours.
The convection module for the
T-SKY eco2
DUO gives you,
at the flick of a wrist, the additional benefits of greater
direct heat emission in the heating up and burning down
phases. Choose whenever you wish between assisted
convection or pure radiated heat.
A new innovation for all T-SKY
eco2 / T-ART eco2
models is the
addition of a manual start-up slide. The individually opera-
ble starting aid for heating provides support for the heat-up
process in the event of difficult wind or eather conditions.
La T-SKY eco2 / T-ART eco2 è dotata di una valvola aria di ali-
mentazione automatica regolata mediante termostato che
si chiude automaticamente dopo la combustione del legno.
Si impedisce così un raffreddamento troppo rapido della
stufa ad accumulo e la potenza calorifica viene p olungata.
La T-SKY eco
2 / T-ART eco2
è dotata di uno sportello con chiu-
sura autonoma. Contemporaneamente la porta del camino
soddisfa i criteri di abilitazione del DIBt per quanto riguarda
l’utilizzo in esercizio non in funzione dell’aria (ventilazione
controllata degli spazi abitativi).
La combustione della legna da ardere avviene dall’alto al
basso nella T-SKY eco2 / T-ART eco2. La combustione top-
down garantisce minori emissioni. Grazie alla combustione
meno inquinante rimangono solo poche ceneri. Con una ca-
rica di legna si può avere un bel fuoco per ca. 2 ore.
Con il modulo a convezione della T-SKY eco2 DUO si hanno
«in un batter d’occhio» i vantaggi supplementari di un’emis-
sione di calore diretta maggiore nella fase di accensione e
combustione. Se necessario, si può scegliere tra il supporto
della convezione e il calore radiante puro.
Come novità tutti i modelli
T-SKY eco2 / T-ART eco2
dispon-
gono di una valvola di accensione manuale. L‘avviamento con
comando individuale per l‘accensione supporta la procedura
in caso di condizioni di tiraggio o climatiche non ottimali.

1. TONWERK STORAGE HEATING
STOVE – A SWISS QUALITY PRODUCT
Thank you for buying a Tonwerk storage heating stove we are sure you will
derive as much pleasure from our product as we do.
These instructions contain interesting and informative facts and all you need
to know about the subjects of heating, wood, and operating your Tonwerk
storage heating stove. Please read these instructions carefully before using
your stove for the first time and keep them in a safe place.
WE ARE SATISFIED WITH OUR WORK WHEN YOU HAVE NO MORE QUESTIONS.
In our energy-conscious times we have made it our mission to extract the
maximum possible energy from the raw material wood with the minimum pos-
sible emissions.
We want to utilise effectively wood, fire, and the heat they generate.
WE HAVE CREATED A LIVING SPACE FOR YOUR WOOD FIRE –
THE TONWERK STORAGE HEATING STOVE!
Your Tonwerk storage heating stove never fails to fascinate with its extraor-
dinary design and a heart of the most innovative technology handmade in 
Switzerland!
1.1  THE STORAGE HEATING STOVE
The storage heating stove is a fireplace made of ceramic or natural stone.
The energy or heat generated by burning wood is absorbed by the ceramic
storage core. Once the wood has completely burned, this core, as a heat ex-
changer, radiates the stored energy in the form of heat at a carefully dosed rate,
releasing it over its surface for an extended time into the environment.
1.2  THE RADIATED HEAT
The human organism responds to radiated heat with a particularly pleasant
feeling. It is physiologically beneficial and soothing.
Since prehistoric times humans have utilised and enjoyed radiated heat. It
is transmitted by electromagnetic waves in the infrared range. Radiated heat
travels through air without loss and without heating this. Not until it encoun-
ters solid bodies like walls, objects, and also people does it generate heat.
This effect is familiar to everyone from sunny winter days.
Even when the air is very cold you can feel the warm rays of the sun on your
skin.
It makes you feel a temperature that is higher than the actual air temperature.
This explains the great benefits and the sustainability of radiated heat.

2.1  WHAT IS WOOD?
Do you know what you are putting in
the firing chamber of your Tonwerk
storage heating stove when you are
filling it with wood
This is 50% carbon, 42% oxygen, 6%
hydrogen, and 2% mineral substances,
nitrogen, oils, resins, tanning agents,
and colorants.
… that is wood!
2.2 ENVIRONMENTAL
PROTECTION
Burning fi ewood releases only as
much CO2 as the tree has absorbed
from the atmosphere during its growth.
And when the fi ewood comes from
nearby there are no additional CO2
emissions from transport.
Wood rotting in the forest generates
the same amount of CO2 as the same
wood burning.
Damp wood damages 
your fireplace and
reduces efficiency!
2.3 BUYING FIREWOOD
Where can I get my fi ewood?
BUYING READY-TO-BURN FIRE-
WOOD
Regenerated ready-to-burn fi ewood
can be purchased from dealers:
stove-ready, stored for at least two
years
• predried, stored for one year
• fresh from the forest
Every dealer has a wood moisture me-
ter that they use to test the wood they 
buy. The ideal residual moisture is 12–
15% and should be no higher!
TREATING FIREWOOD YOURSELF
Unseasoned wood can be purchased
from the forestry office, owners of
woodland, or the community:
trunks lying in the forest
• seasoned trunks by the wayside
Whether you have cut your own wood
or bought it, the important thing is:
the wood should be dried for at least 
two years before it is burned!
2.4 DRYING AND STORING
   WOOD
DRYING
The water content of fi ewood has a
great effect on its burning properties.
Your wood should be as dry as possi-
ble. Only then can it give off much heat
and burn without polluting the envi-
ronment. Freshly cut wood can contain
between 45 and 60% moisture depen-
ding on the season and type. After
the optimal drying this water content
drops to below 15%. Depending on the
wood type this can take about two ye-
ars, and even longer for some kinds.
STORAGE
If
fi ewood is to dry thoroughly, it must
be cut into small pieces.
Check this yourself: the circumference
should be max 20–25 cm. Store the
wood out of doors, protect it from rain
and snow, and make sure it is well ven-
tilated.
2.5 WOOD TYPES AND
  CALORIFIC VALUE
The calorific value describes the heat
energy released when one kilogram
of fuel is burned under specific condi-
tions.
The calorific value is based on the vo-
lume specified in stacked or solid cu-
bic metres.
The various wood types have various
calorific alues:

Loose  cubic  metre  (lcm): The loose
cubic metre is a measure for chopped
fi ewood that is loosely packaged for
trade and transport. One loose cubic
metre is 0.7 steres or about 0.5 solid
cubic metres.
NOTE THE SPECIFIED UNIT OF 
MEASUREMENT WHEN ORDERING!
Solid cubic metre (scm): As its name
suggests, the solid cubic meter corre-
sponds to one cubic metre of solid as
opposed to stacked wood.
Stacked  cubic  metre  (stcm)  or  stere 
(st): A stacked cubic metre or stere
corresponds to one cubic metre of sta-
cked wood including the gaps between
layers. One stere equals 0.7 solid cu-
bic metres.

2.7   WHAT HAPPENS WHEN WOOD BURNS
Burning or combustion is a rapid oxidation of substances forming flames. When wood
burns, the oxygen in the air combines with the carbon and hydrogen in the wood. In
the process, energy is released in the form of heat and light. In the ideal case the
products of complete combustion are only carbon dioxide, ashes (formed primarily of
the wood’s mineral constituents), and water.
The combustion process on fi ewood can be divided roughly into three phases.
Heating and drying  In this first phase the water and other volatile substances
stored in the fi ewood evaporate.
Pyrolysis  In this second phase the fi ewood decomposes at temperatures from
about 150 °C.
Actual combustion  In this third phase the gases formed in the first two phases re-
act with additional oxygen from the atmosphere to form carbon dioxide and water.
Also any remaining charcoal burns completely with time in the combustion zone.
Only ashes remain as the single residue of combustion. Each phase of combustion
can be observed very easily on an open fi e.
Burning wood is a
proactive contribution
to climate protection!

3.2 MODEL –
SELF-CLOSING FIRING
CHAMBER DOOR
The Tonwerk storage heating stove is fit
ted as standard with a self closing firing
chamber door. This is an important opera-
ting and safety element. The door closes
automatically as soon as it is released.
Consequently the Tonwerk storage he-
ating stove is suitable for connection to
flues with multiple installations (several
Model 1 stoves connected to the same
flue).
3.5  RATINGS PLATE
The type plate is found on the left in-
ner side of the housing.
3.6 OPERATION
INDEPENDENT OF
INDOOR AIR
Operating your stove independently
of indoor air requires a direct exter-
nal supply of air to the air nozzle in
the base of the stove. The connec-
tors must be airtight. Your Tonwerk
storage heating stove is designed for
operation at an air/gas flue or with a
separate combustion air line ( FC61X ).
Check regularly that the firing
chamber door closes properly and the
air and gas ways are tight.
3.4 CE CONFORMITY
The manufacturer, Tonwerk Lausen AG,
confirms that the Tonwerk storage he-
ating stove conforms to the stan dards
under EN 15250 and that the quality
requirements are constantly monito-
red.
Room sealed appliances and multiple
connection of the flue
For air independent operation with
domestic ventilation is an multiple
connection of the flue only allowed
inside the same living unit.
4.3 GENERAL SAFETY
INSTRUCTIONS
• Never leave children alone or unat-
tended at a burning fi eplace.
• Teach your children how to behave pro-
perly and operate safely the fi eplace.
Every stove gets hot when fi ed: risk
of burning!
• Avoid touching the outside surfaces
when the stove is operating.
• Do not burn refuse or painted wood.
• Dispose of the ashes only after they
have cooled completely.
• Inform your specialised dealer wit-
hout delay of defect gaskets.
Observe the information in our
operating instructions and make a
proactive contribution to fi e pre-
vention and the protection of our
environment.
4.4 CHIMNEY SAFETY 
INSTRUCTIONS
The required chimney flue shall be 12
Pa. If the height and cross-section of the
chimney cannot be adapted to meet the
requirements, this may result in wind-
related problems and consequently dis-
rupted combustion, as well as formati-
on of condensation. If the chimney flu
is too high, draught stabilisers shall be
installed. Local and national regulati-
ons must be complied with.
If the chimney catches fire, immediately
call the fire brigade.
4.5 CONDUCT DURING
MALFUNCTIONS – 
SHUTTING DOWN
SAFELY
In rare cases, also a pilot fi e can fail to
generate a draught in the flue
You must then ask your chimney
sweep for advice. On no account must
you attempt to light a larger fi e. When
smoke escapes from your stove, air
the room immediately and contact
your chimney sweep. You should then
refrain from firing our stove.

5. OPERATING INSTRUCTIONS
5.1  BEFORE FIRING THE
STOVE FOR THE FIRST
TIME
Dear Customer, You have now been
instructed by one of our specialised
dealers on how to fi e your Tonwerk
storage heating stove.
In these operating instructions we
wish to set down each step that you
must take if you are to encounter no
problems when operating your Ton-
werk storage heating stove.
Read through these operating instruc-
tions carefully and keep them in a safe
place. Your specialised dealer will be
pleased to assist you with any que-
stions you may have.
5.3.4  CLOSING THE FIRE CHAMBER DOOR
The optimal closing of the fi e chamber door allows for convenient filling and main-
tenance of the fi e chamber.
If your stove is used in a house/flat with an incoming and outgoing ventilation sys-
tem, the door must be able to close automatically at any time.
In this case, using the door lock is at the user’s own risk.
Operation: Make sure not to press against the closed door in order to prevent da-
mages to the mechanics.
5.3.5  VENT PIPE AND VENTILATINGSYSTEM
Operation with indoor air: Extractor hoods and ventilating systems can affect the
operation of your Tonwerk storage heating stove. Please make sure that there is
adequate incoming air for multiple installations.Operating the extractor hood and
ventilating system can force dangerous flue gases out of the stove and into the
room. Under the firing regulations, joint operations are permitted only in conjunc-
tion with a flue gas controller. When the extractor hood or ventilating system is put
into operation, at least one window in the room must be open.
Operation independent of indoor air: Make sure that the room is adequately ventilated
when your stove is operating independently of indoor air. When the firing chamber door
is opened for more fi ewood, there must be no sustained underpressure in the room.
5
.3.6  HEATING IN THE TRANSITION TIME 
AND IN DIFFICULT CONDITIONS
In damp or foggy weather, at outdoor temperatures from 15 °C, and during the tran-
sition time you are advised to light a pilot fi e before firing the stove proper. This
serves to displace the cold, heavy air in the chimney and to create the right condi-
tions for the optimal extraction of smoke.
This pilot fi e is lit with paper in the chimney’s inspection aperture until extraction
is assured.
5.3 GENERAL INFORMATION
5.3.1  PREPARATIONS
FOR FIRING
Have ready an adequate supply of
chopped fi ewood, ecofriendly lighting
aids, and kindling. You are best storing
the wood in a warm room for a number
of days before firing
5.3.2   INSTRUCTIONS FOR 
FIRST-TIME USE OF
THE TONWERK 
STORAGE STOVE
1. Heat your stove for the first time
with around 3/4 of the quantity of
wood specified in the operating in-
structions (around 4 kg), without
piling it up.
2. Repeat the above process a 2nd
time, after a minimum of around 8
10 hours have elapsed, and then
after another 8 hours have elapsed,
operate it with a full load of wood,
or pile up as desired.
5.3.3  DRYING THE 
STOVEPIPE PAINT

The supplier of the ventilation system
must ensure that the pressure does
not exceed 4 Pa.
6. FIRING THE STOVE
Now place around 6 wooden logs (around 33cm long, each around 0.8 kg in weight)
into the fi ebox. The firing chamber is slightly inclined to the rear, to ensure the
wooden logs remain at the back, against the rear wall of the firing chamber and do
not topple over against the pane of glass. If the wooden logs are cut at an angle and
resting against the fi ebox door, you must turn the logs until they are inclined to the
rear. Place pairs of wooden logs behind each other, as compactly as possible en-
sure that free space of around 2cm is allowed between the wood and the side wall
of the fi ebox. The front ash collar must not be covered with wood.
Insert 1-2 fi elighters (impregnated starter cubes) in the middle of the standing
wooden logs and cover them with a generous quantity of small kindling. Now light
the fi elighters and release the fi ebox door.
The firebox door will automatically close and establish a seal.
Close the heating start flap when flames em ge, to ensure optimal through-
ventilation for the storage core. For this purpose, push the control knob into the
original position as far as it will go.
Once the wooden logs have burnt down, insert another 2 logs, each around 0.8
kg. Depending on the degree of compactness and flue d aught, the fully-loaded
quantity of 6 kg will burn down in 120 to 150 minutes.
CAUTION!
Avoid opening the fi ebox door at any time during the combustion and burnout
phases.
Manual model 
T-SKY eco2 / T-ART eco2
Open the fi ebox door. Open the com-
bustion air slide, by moving the con-
trol lever all the way to the right to the
“Symbol +”. Open the heating start
flap when initial heating is difficult, by
pulling the control knob backwards.

When the wood has burnt completely
and all the flames have disappeared,
switch the combustion air slide to the
“Symbol –“ which shuts off the air sup-
ply.
Automatic model
When the wood has burnt completely
and all that is left is residual embers
in the fi ebox, the automatic air flap
closes on its own.
Automatic model T-SKY eco2/ T-ART eco2
Open the heating start flap when initial
heating is difficult, by pulling the con-
trol knob backwards.
NOTE!
If the fi ebox door does not close

the lock when cleaning), the sto-
rage stove must not be operated.
In this case, try to bring the lock
latch into the starting position or
inform the specialist dealer.

the storage heating stove, simply leave the convection module open. Bear in mind
that direct heat emission reduces the heat storage capacity and causes your sto-
rage heating stove to cool down faster.
6.3 ADDING MORE WOOD
When you want to heat for longer, add two pieces of fi ewood when there is an
adequate basic fi ebed. When building the fi e or adding wood, distribute any re-
maining coals evenly with a poker.
Slowly open the firing chamber door, first a gap, so that the pressure in the firing
chamber is equalised. This helps to prevent ash from flying into the oom.
Distribute the basic fi ebed evenly over the firing chamber base, place one-off
two pieces of fi ewood against the rear wall of the combustion chamber, and
release the firing chamber door. The new fi ewood ignites in a few minutes and
burns from bottom to top.
No fi ewood may be added when the basic fi ebed is higher than the ash shield.

:
When the wood has burnt up completely and all the flames have disappeared, switch
the combustion air slide to the “Symbol –”, which shuts off the air supply.
Automatic model:
When the wood has burnt up completely, the thermostatically-controlled air-inlet fla
closes automatically, which helps ensure lasting emission of the radiant heat.
NOTE!
Opening the firing chamber door always and automatically opens the air supply
fla . This closes again when the fi ewood has burned completely and there are only
embers in the firing chambe .
When your storage heating stove is not connected to an external supply of fresh air, please make
sure that the room is ventilated adequately while the firewood is burning.

7. CLEANING AND CARING FOR YOUR STOVE
7.1 MANUEL VENTIALATION ADJUSTING DEVICE
When you do not intend to fi e
the stove for a long time after
cleaning or opening the firing
chamber door (e.g. during the
summer months), please press
the manuel ventialation
adjusting device to close the air
supply valve.
Under no circumstances 
may the manuel
ventialation adjusting
device be pressed to 
stop the supply of air 
prematurely to burning 
firewood!
!
Empty the ash drawer as soon as it is full. Only
empty when the stove is cold into a fireproof
container (embers - fire hazard). If necessary
you can clean the window with a moist cloth
and some ashes. Repeat for stubborn soiling
or use a special flue window cleaner. When
using a fireplace glass cleaner, please make
sure no liquid enters the space between the
window and the door chassis. The liquid can
damage the printing on the window.
Opening the firing room door for cleaning
purposes also opens the air supply fla. We
recommend cleaning the stove before it is
fired again.
Rough surfaces on the outer cladding can be
vacuumed off with an upholstery attachment.
Polished surfaces are cleaned with a spraywet
cloth. The provided cleaning stone is used to
remove stub-born soiling. Under no
circumstances must you use hard brushes or
chemical cleaning agents. The optimal
functionality can be assured only when the
chim-ney, stovepipe, and stove are cleaned at
least once a year.
7.2 OPERATING MANUEL VENTIALATION

8. TIPS & TRICKS
Wood does not ignite when stove 
is fired; fire just smoulders away; 
fire extinguishes:
• kindling unsuitable
• wood too damp
• fi ewood too thick
Heavy sooting in the firing 
chamber; heavy sooting on the 
window: 
open the combustion air supply
• too little wood
• fi ewood damp or too thick
Smoke escapes from the stove:
assure adequate extraction in
the chimney, light pilot fi e
provide for adequate supply of air
8.1  POINTERS
When operating the T-SKY with ba-
lanced flue operation, it is advis-
able after each period of heating
to have the state of the door seal
checked by a professional and re-
placed as required.
The fi ebox is made of vermicu-
lite and high-quality fi ebricks. All
types of refractory material are
subject to thermal stresses, which
may lead to cracks. For this rea-
son, any crack in the lining of the
fi ebox is a sign of natural wear
and tear.
Your specialised dealer will be 
pleased to assist you with any 
further questions you may have.
