VARDE OVNE Aura 1 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: 12,5 cm Distance to furniture in front of stove: 80 cm
If the stove is placed near combustible material, you shall be aware that the chimney can
have other demands for safety distances to combustible materials than the stove. If there
is doubt, then consult with your local chimneysweeper.
If the stove is installed with insulated chimney all the way down to the flue collar, following
safety distances to combustible material can be used: Sides:30cm Rear:8cm: Front:85cm.
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.
Flooring:
If the floor where 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. Cover-
ing 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.
Weight of Varde Aura 1 104 kg. Weight of Varde Aura 2 101 kg.
Weight of Varde Aura 3 106 kg. Weight of Varde Aura 3 soapstone 190 kg.
Weight of Varde Aura 11 113 kg.
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.
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 above
the door for combustion air (alternatively, shortly leave the ash-pan a little open if there is
no wind and no draught in the chimney), thus allowing the fire to catch on. Always remem-
ber to close the ash-pan 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-lid and also the
shaking grate again.
Regulations
All local regulations as well as
National and European, should be
adhered to when installing your
stove.
All Varde Ovne stoves are closed
fireplaces.
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.
Combustion / Secondary air
Pre-heated air for the combus-
tion process, the amount of
which can be altered according
to the desired room tempera-
ture, and the effectiveness of
the chimney. A high level of
chimney draught requires a
lesser intake of combustion air.

Tertiary air
is constantly added air, which
makes the stove burn even
cleaner, and lowers the content
of tar and soot in the combus-
tion process to an absolute
minimum.
At optimal combustion settings,
glass and combustion chamber
will be burnt completely clean,
and the remaining amount of
ashes will be minimal.
What kind of wood to use?
Generally, beech wood is con-
sidered the best type of wood
for burning. It burns evenly
without producing much smoke
and the ashes are clean and
take up little space. Ash, birch
and maple wood are fine alter-
natives.
Overheating
Occurs if too much wood is
placed in the stove or if the
combustion receives too much
air.
Vermiculite fire bricks
A special non-inflammable
material. The vermiculite fire
bricks both isolate and protect
the stove from attrition. Vermicu-
lite fire bricks and smoke plate
are not covered by the warranty.
Vermiculite is a very porous
material, therefore handle with
care. When refilling the stove,
put in the wood carefully, use
the glove.
In most instances, however, you will have to arrive at the best combustion air settings yourself,
as the height and diameter of your chimney, as well as the quality of the firewood are decisive
factors in determining how your particular stove is best set (see also the section on trouble-
shooting on next side).
When refilling the stove with wood, we recommend opening the stove door only once embers
are left in the combustion chamber. Opening the door whilst the flames are still burning and
producing smoke and gas, might cause smoke to slip into the room instead of up the chimney.
What to burn
This Varde stove is tested and approved for the burning of wood. Only dry wood with a mois-
ture content of maximum 18 percent and the size to fit into the combustion chamber should be
used. The burning of moist wood will result in an increased amount of tarry soot, pollution and
uneconomic fuel consumption. Newly chopped wood contains about 60-70 percent moisture,
which makes it completely unsuitable as fuel. Allow newly chopped firewood to dry in an open
shed for a year before using it in the stove. Split firewood with a diameter larger than 10 cm.
Use firewood with a length on 25-30 cm.
The use of larger quantities of fuel than recommended in the table page 2 will overtax the stove
and result in increased temperatures in the chimney as well as a lowered efficiency. This may
cause damage to both chimney and stove, and the annulment of the warranty. Also, never use
toxic materials such as chipboard, painted or impregnated wood.
Maintenance and cleaning
As any piece of equipment in daily use, your stove needs maintenance.
The stove should only be cleaned when cold. Use a dry cloth for cleaning the exterior of the
stove.
Clean the interior regularly by removing ashes, soot and tar from the combustion chamber. The
smoke plate should be removed for cleaning as the reverse side will be covered in dirt and
soot. Finally check that the smoke's pathway through the smoke pipe and chimney is complete-
ly clear. You should also inspect the gaskets in the door and the ash-pan for signs of wear.
Replace them if permeable. Also, remember to oil the hinges of the door as required.
Empty the ash-pan regularly. It can be emptied into your dustbin, as long as you make sure it
contains no hot embers.
When in doubt as how to clean your stove, contact the dealer from whom you bought your
stove, or your chimney sweeper. It is especially important to check the stove and its chimney
for blockages after a long period of non-use.
The enamelled surface of the stove may wear down at certain places if the stove is
overheated.
Worn surfaces, however, can be repaired with a special Senotherm® spray paint, available at
your local vendor.
The plates in the combustion chamber are Vermiculite plates and will eventually be worn – as
will the smoke plate. Should you accidentally break a plate, for instance by hitting it hard with a
piece of wood, this does not effect the quality of the combustion. You need not replace the
plate until the gap is 5 mm. wide.
The door is constructed with a spring which automatically swings the door shut.
This may be a function required by existing regulations.
The springs is placed in both hinges, and can be removed, if you do not want this option.
Only use original spare parts from Varde Ovne.
Do not make any unauthorised changes.
All external parts of the stove become hot during use, too. Therefore exercise
necessary caution when the stove is in use.
Primary air valve
The valve on the ash-pan is for
access of lightening-air.
- When the valve is closed (the
small handles is horizontal), then it
is in burning position. (the valve is
closed).
- When the valve is opened (the
small handles is vertical), then it is in
lightening position, and a big flow of
primary air is coming into the com-
bustion chamber.
Remember to turn the valve back to
burning position when the fire burns
steady.

Troubleshooting.
Smoke enters the room:
 Not enough draught in the chimney.
 Inspect the smoke pipe or the chimney for blockage.
 Clean the inside of the stove removing soot from the upper vermic-
ulite / smoke plate.
 Make sure the height of the chimney is correct.
The glass or the chimney soot up:
 The wood is too moist.
 Not enough secondary air is applied to the combustion process.
 You may have shut off the supply of primary air too early when
lighting up the stove.
 There always have to be clear flames in the combustion chamber.
The heat is emitted from the stove:
 The wood is too moist (all energy goes into drying it) or of a poor
quality.
 Inspect the position of the smoke plate and make sure there is free
passage for the smoke.
Combustion is too intense:
 Gaskets in the door or the ash-pan are no longer tight and need
replacement.
 The chimney draught is too strong - apply a draught control.
The shaking grate is stuck:
 Inspect the grate for jammed wood, nails or the like.
 Make sure the lever is placed correctly.
Height of chimney
If in doubt, contact your local
stove dealer. He will be able
to inform you of the correct
height.
