Others cover plate (types) have 4 holes where the plate have to be placed on the 4 pins in the
bottom of the burning chamber.
When you wish to push the ash into the ashtray please remove the coverplate and use it to push
the ash down into the ash tray.
National and European norms
The regulations in force at the time in question, including those that refer to national and Euro-
pean standards, must be respected when installing the wood-burning stove. Contact your local
dealer for further advice and guidance in connection with mounting. Notify your Hetas installer
before you use your wood-burning stove. It must be ensured that there is suffi cient airfl ow for the
combustion in the stove, so care must be taken concerning closely shut windows and doors that
may hinder the fl ow of air to the combustion.

Safety references

The surface of the stove as well as knobs, handle, window, smoke pipe, etc. become very hot
when the stove is in use. Touching these parts without necessary protection (glove or other pro-
tective material) can lead to burns.
Remember to make children aware of this danger and make sure to keep them away from the
wood-burning stove when it is in use. For this purpose TermaTech off ers various grates for the
protection of children. (Ask your dealer)
Allowed in the wood-burning stove
Only use dry and clean wood for combustion in the wood-burning stove.
Maximum size of logs used in the stove is up to 30 cm in length and 10 cm in diameter.
Maximum fi lling:
Wood must not be added to the wood-burning stove above the tertiary holes of the rearmost
vermiculite/insulation plates, corresponding to approximately 15 cm from the bottom plate of the
combustion chamber.
Only use dry wood. The burning of waste, synthetic materials and other treated or impregnated
materials is not allowed as it is very hazardous to the environment. Furthermore the stove and
the chimney will be damaged by these materials. There is a danger of emission of unhealthy sub-
stances which can also lead to complaints from neighbours.
Dry and clean wood has a maximum of 20% water which is achieved with outdoor storage for
between 1 year (soft wood) and 2 years (hard wood). The wood must be in contact with air du-
ring storage so the moisture can get out of the wood.
Firewood is not meant to burn overnight. Never close off the airfl ow completely, instead let the
fi re die out and light it again when you need it.
We warn against closing off the airfl ow completely. The wood-burning stove can only burn sensi-
bly and environmentally friendly if there is suffi cient airfl ow for the combustion.
Cleaning and checks
The wood-burning stove and the smoke pipe should be checked and cleaned once a year. The
chimney must also be cleaned by the chimney sweep that will set the necessary intervals for
cleaning / sweeping.
The wood-burning stove should be checked by a professional about once a year.
After the chimney sweep has cleaned the pipe, he will often clean the burner inside as well.

Combustion air

Combustion air is a precondition for a good and clean combustion.
The air is normally taken from the room where the wood-burning stove is mounted, however
in some circumstances it may be necessary to provide extra air in the room where the stove is
placed. This can e.g. be done by mounting an air valve in the room's outer wall. Air valves that
supply necessary combustion air must be kept free from blockage.
An exhaust fan in the same room or close to the wood-burning stove can also have a negative
eff ect on the combustion (at worst it can lead to exhaust gases in the room, even with the stove
door closed). Therefore, in the above case, the wood-burning stove and the exhaust fan must
never be in use at the same time.
The amount of air that must be used for combustion is approximately 8.2m3/per kg. of fi rewood.
The TT20/21 models are available with combustion air branch, which has a connecting pipe/spigot
of Ø80mm, use an air hose of Ø80mm.
Ask your dealer for further information.
Adjustable feet (not for TT20Streamline+R)
The enclosed adjustable feet are to be used if the fl oor is uneven or they can also be used to
create the impression that the stove is "fl ying" / "fl oating"

Distances to fl ammable materials using UNINSULATED fl uepipes*
The stove must be put on a non infl ammable foundation. This foundation must as a minimum
cover 150 mm on each side of the stove and 300 mm in front of the stove.
For infl ammable material like infl ammable walls made of wood, furniture, etc. the following mini-
mum distances apply for safety reasons (*These distances only apply to the stove. Other distan-
ces apply to fl uepipes):
150 mm behind the stove to fl ammable material.
350 mm beside the stove to fl ammable material.
125 mm behind/beside if mounted 45° in a corner.
1000 mm in front of the stove to fl ammable material.

Distance to non-fl ammable materials
It is recommended that there is a minimum of 50-100 mm behind and beside the stove so the
stove can dispose of the heat, this distance makes cleaning of and around the stove easier. In ad-
dition, refer to the relevant Building Regulations.

Requirements for the chimney

The chimney must be of suffi cient height so the draught conditions are okay the smoke does
not bother anyone. Good draught in the chimney is crucial to the stove working as intended and
burns as environmentally friendly as possible. The height of the chimney must typically be a mini-
mum of 3.5 m from the top of the stove to the top of the chimney.
The chimney must have a minimum internal diameter of Ø150mm.
The chimney must be equipped with an easily accessible cleaning hatch. All joints and connec-
tions must be tight and the chimney must be able to provide a draught of at least 1.2 mm water
gauge (12Pa).
It is possible to connect the wood-burning stove to chimneys that are also used for other purpo-
ses. However, the concrete conditions must be assessed by the fi tter and/or chimney sweep.
If the stove is to be mounted with back/rear exit the following is done:
The round, welded or screwed cover plate at the back of the stove is removed. Then the cut-out
piece on the base-plate is removed (the thin division plate). Be careful not to drop the piece bet-
ween the back plate and the stove! This is best done with a screwdriver / chisel or pliers.
Finally the screwed smoke cover is removed and then the exhaust branch can be mounted.
Remember to fi x the smoke cover at the top of the stove before use.
Demands for the fl oor:
The foundation must be able to bear the stove and possibly the chimney's weight.
INSTALLATION INSTRUCTIONS IN SMOKE CONTROL AREAS
Installation in a smoke control area requires the additional assembling / installation of the "Dam-
per control unit" which must be installed by the installer. See drawing and picture on page 33 .
LIGHTING INSTRUCTION
The fi rst time
The fi rst time the stove is lit is must be done gently as all the materials need to get use to the
heat. The Senotherm varnish that the stove is painted with will harden the fi rst couple of times
the stove is heated, and it may cause some odour nuisances. So make sure that you have proper
ventilation. Do not touch the painted surface, when the stove is hot. The painting has to harden
up fi rst.
Use of the stove
Below is the procedure used for testing/approval of the stove. It is this procedure that will lead to
the best combustion for the given chimney. Firewood amount and damper setting can be adjusted
to the individual need for heating and the draught in the concrete chimney.
