Installation and user’s manual: TT40

(EN 13240/CE marked / Sintef)

Congratulations on your new TermaTech wood-burning stove.
In order to enjoy your new wood-burning stove as much as possible it is important that you read
this user’s manual thoroughly, even if you have previously owned a wood-burning stove.
Before you can really enjoy your wood-burning you have to become familiar with it. Already after
firing the first few times you will begin to be familiar with your new wood-burning stove. In the
following sections we will go through the use.

TermaTech wood-burning stoves are tested and approved according to the EN 13240 (CE) norm
as well as Sintef approval in Norway, i.e. according to some of Europe’s strictest demands for
wood-burning stoves.

Naturally the stoves are also in accordance with the requirements in the Danish ’Order concerning

wood-burning stoves’ which came into effect on 1.6.2008. The approvals give you a guarantee that
your wood-burning stove is approved according to the most important Scandinavian and European
standards which means that the stove complies with a number of requirements for among other
things safety, environment and efficiency which leads to good firing economy.

1. Before installing the wood-burning stove

When installing your wood-burning stove you must make sure that all local laws, incl. those that
refer to national and European standards, are followed. It is always a good idea to consult your
chimney sweep before installation. It must be emphasised that the chimney sweep always has to
approve the installation, even if a wood-burning stove was installed previously. You also have to
make sure that the placement complies with the current rules in the Building Regulations for small
houses. See the below statement of minimum distances to flammable materials. If the wood­burning stove is to be installed near a non-inflammable there are no requirements for minimum
distance, but we recommend 8-10 cm behind the stove for cleaning purposes.

2. Distance to flammable material

All distances have been determined in connection with approval of the wood-burning stove.
100 mm behind the stove to flammable material.

200 mm beside the stove to flammable material.
900 mm in front of the stove to flammable material.

100 mm behind
200 mm to the side
900 mm in front

The floor underneath the wood-burning stove must be non-inflammable or coated with a non­inflammable material. The non-inflammable material, e.g. a steel plate, glass plate, slate/ imitation
slate or tile, must be placed so it reaches at least 300 mm in front of the wood-burning stove and at
least 150 mm to each side of the opening of the wood-burning stove.

3. The chimney

The chimney is the lung of the wood-burning stove, i.e. a chimney with good draught is a
precondition for good combustion. You must use a chimney with a diameter of at least Ø150 mm
which is the equivalent of an internal diameter of 175 cm² for your TermaTech stove. It is important
to follow the directions in the Building regulations for small houses and to make sure that the
existing or new chimney is high enough to ensure optimum draught in the wood-burning stove. The
chimney must be of sufficient height so the draught conditions are okay and the smoke does not
bother anyone. We recommend 80 cm above the ridge. If the chimney does not have sufficient
draught smoke nuisances and poor combustion can occur. If the chimney draught is not sufficient
an evacuator can be mounted on the chimney. If there is too much draught, a damper can be
mounted on the chimney. Ask your dealer or your local chimney sweep if your have doubts.

4. Ventilation

Combustion air is a precondition for a good and clean combustion. In most cases there is sufficient
air in the room. However in special cases 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 exterior wall of the
room. Air valves which add necessary combustion air must be kept clean.

5. Before use of the oven

It is very important that you make sure that the heat cover above the firewood compartment is
mounted in the stove; it is loose from the manufacturer and could fall down during transport. Place
the heat cover right below the door/bottom of the combustion chamber so it protects the firewood
compartment against radiant heat. The heat cover is mounted by letting the 4 pegs rest on
convection holes inside the firewood compartment.

6. Before the first lighting

The first 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 first couple of times the stove
is heated, and it may cause some odour nuisances. So make sure that you have proper ventilation.

7. Lighting and firing in the wood-burning stove

It is very important to heat your wood-burning stove and chimney as fast as possible in order to
create optimum draught in the chimney and achieve the best combustion. A wood-burning stove
made from sheet iron will give during lighting/cooling, this may result in creaks, that is completely
normal for the stove and should not be considered as a complaint.

1. When you light your wood-burning stove we recommend the use of kindling, i.e. thin
wooden sticks (app. 1.2 – 1.5 kg), in the bottom of the stove, laid in a criss-cross
pattern as a log house. Put 2 firelighters in the middle and light them (never use
alcohol, petrol, other flammable liquids or newspapers or magazines for lighting).

2. Open air damper for lighting air (the damper at the bottom of the wood-burning
stove), this is done by pushing the rod under the door all the way to the right.

3. Leave the door ajar so there is an opening of about 2-3 cm. Leave the stove like
that for about 8-10 minutes before you close the door completely.

4. The air damper at the top of the oven, above the door, is opened completely by
pushing it to the right.

5. Let the kindling burn to a solid layer of embers (there are no more flames) before
firewood is put into the wood-burning stove.
