VARDE OVNE Thurø 1 Installation And User Manual

Installing the stove:
According to existing regulations, stoves must be placed with the following minimum
distances (in centimetres) to inflammable walls and materials:
Sides: 30 cm Rear: 20 cm Distance to furniture in front of stove: 100 cm
If walls are non-inflammable, the stove can be placed closer to them. However, we recom-
mend a minimum distance of 5-10 cm. to allow for cleaning behind the stove. The cleanout
gate must be accessible.
Optimal combustion can only be obtained if fresh air is constantly admitted. It is important,
therefore, to ensure that this is the case.
The best way to provide a steady flow of fresh air is by installing 1-2 air vent's) in the room
where the stove is situated. (one in each side of the room).
Flooring:
If the floor on which the stove is to be placed is inflammable, the floor must be covered
with non-inflammable material, such as a steel or glass plate, floor tiles or artificial slate,
covering an area of at least 15 cm. from the sides of the stove and at least 30 cm. from the
front of it.
With regard to the front, however, we recommend 50 cm.
Also, the bearing construction must be capable of carrying the combined weight of stove
and chimney.
The weight of Thurø 1 is: 117kg.
The chimney:
Always use a chimney with a diameter of at least 15 cm. This corresponds to a clear of
175 square centimetres. Make sure the chimney is of a sufficient height, that it draws well
and that smoke does not bother your neighbours.
We recommend that you fit your chimney with a damper, allowing for draft control. This
may prove particularly important on windy days.
Note: the damper must never shut off draught completely – always allow at least 20
square cm free passage through the chimney.
With nominal usage the stove has tested a Smoke flow of 5,5 g/second and with a smoke
temperature of 310° C in a room of 20° C.
Varde stoves are always fitted with a smoke plate which redirects smoke to make its way
to the chimney as effectively as possible. This ensures that the heat from the smoke is
emitted inside your home rather than outside it. The smoke plate is moveable and placed
on top of the Vermiculite fire brick side plate. You should make sure that it is pushed all
the way back against the back wall of the combustion chamber.
How to light and stoke a fire:
The first time you light up the stove the enamel will temper, and give off some smoke and
a slight smell. We recommend that you leave doors and windows open, as airing the room
will make the smell disappear. This tempering softens the enamel making it susceptible to
damage. Therefore exercise caution and avoid touching the enamel. Likewise we recom-
mend opening the door to the stove at regular intervals for the first hours to prevent the
insulation rope from sticking to the enamel.
Never use highly inflammable fluids such as spirit and petrol for lighting up! Instead, use a
crumpled up piece of newspaper or kindling blocks topped by 10-15 small sticks (c. 2 kg.).
A thin layer of ashes at the bottom of the stove makes lighting up a fire easier.
Before lighting up the stove, open the shaking grate by pulling the lever all the way out.
Then open the valve on the ash-pan for access of primary air and open the valve under
the ash-pan for combustion air (alternatively, shortly leave the door a little bit open if
there is no wind and no draught in the chimney), thus allowing the fire to catch on. Always
remember to close the door again, otherwise the stove can be overheated, and this is not
covered by the warranty.
When the fire burns steady, then remember to close the valve on the ash-pan again, until
its c. 10 % open.

Draught conditions
Consult your local stove dealer about
how best to adjust the draught in your
chimney.
Chimney Fires
Should your chimney catch fire, cut
off the air supply to the stove's
combustion chamber and contact
the emergency services. (The ma-
jority of fires die out after the oxygen
supply is cut off). Following this, the
least you should do is to contact
your chimney sweeper, who will
check your stove and chimney for
damage.
Continual fresh air
A continual supply of fresh air is
required in the room in witch the
stove is situated.
This can be achieved by installing 1
-2 vents, whilst also ensuring that
these can not be blocked.
The shaking grate
The shaking grate is situated at the
bottom of the combustion chamber.
The ashes will be shaken into the ash
-pan by the pulling and pushing of the
lever.
Primary air
Also known as ´sub-air´, the air which
is drawn into the combustion cham-
ber through the air valve on the door.
