2.6. Regulation - and smoke dampers mounted on the chimney

If the chimney is provided with at regulation-/smoke damper it should only be opened up to 80%
of the aperture area.

2.7. National og European norms

The regulations in force at the time in question, including those that refer to national and
European standards, must be respected when installing the wood-burning stove. Contact your
local dealer for further advice and guidance in connection with mounting. Notify the chimney
sweeper before you use your wood-burning stove.

2.8. Airflow requirements for the wood burning stove.

The wood-burning stove require air for it to function safely and environmentally friendly. If the
room/house where the stove is installed is too tight, there will not be sufficient air in the house
and thereby in valve of the stove. If there is not adequate air the stove will soot the window and
the chimney, irritate the environment and neighbours and in worst case the fire will die out. For
these reasons always make sure that there is enough air in the room. Please note that if a venti-
lator is installed in the house an underpressure can be created (similar to an extractor fan) which
in worst case can result in reverse smoke flow thereby out through the valve of the stove and into
to lounge/room. This can be dangerous (smoke poisoning) and at the least soot the house. Read
also section 3.4.

3.0. Combustion instruction

3.1. Intermittent combustion

Your new wood-burning stove has been approved for intermittent burning and not for continuous
burning. This means that the fire burns correctly with a small amount of wood with a burning
time of approx. one hour between loading.

3.2. Lighting the first time

The first time the stove is lit it must be done gently. All materials will for the first time become
very hot. The varnish (Senotherm UHT) that the stove has been painted with will harden during
heating. Do not touch the varnish when it is warm and soft. This may cause unpleasant odour. It
is therefore recommended to ensure good ventilation the first few times you light up.

3.3. The grate at the bottom of the burning chamber

The grate which lies at the bottom of the burning chamber ensures a good clean combustion as
air can pass through. The ashes fall through the grate into the ash box. When emptying the ash
box please remove the grate in order to clean the remaining ash into the ash box before empty-
ing.

3.4. Combustion air

Adequate combustion air is a precondition for good and clean combustion.
The air is normally taken from the room in which the stove is mounted. However, under some cir-
cumstances it may be necessary for provide extra air in the room where the stove is placed. This
can for example 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 stove can also have a negative effect 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 exhaust fan must never be in use at
the same time. The TT70 series are delivered with a direct air connection. To secure that the
combustion air is not taken from the room one can install an air hose Ø80mm on the direct air
connection. This air hose can be led through an outside wall so that the combustion air is taken
from the outside. Ask your dealer for further information.

3.5. Heating materials for the wood-burning stove

Only use dry and clean wood in the wood-burning stove. The water content should be between
12 and 20%. The maximum log length used is the width of the combustion chamber minus 4cm
(width of the combustion chamber can be found under 11.0) and 10 cm in diameter.
The burning of synthetic materials and impregnated materials is not allowed as it is damaging to
the environment. Furthermore, the stove and chimney will also become damaged with the use of
such materials. There is furthermore a danger of emission of unhealthy substances. The wood-
burning stove is not meant to "burn overnight". Never close off the air flow completely, instead let
the fire die out and light it again when needed.
We warn against closing off the air flow completely. The wood-burning stove can only burn sensi-
bly and environmentally friendly if there is sufficient airflow for combustion.

3.6. 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.
