Installing the stove:
According to existing regulati ons, stoves must be placed wi th the following minimum
distances (in centimetres) to i nflammable walls and material s:
Sides: 30 cm Rear: 12 ,5 cm Distanc e to furniture in fr ont of stove: 80 cm
If walls are non-inflammabl e, the stove can be placed cl oser to them. However, we recom-
mend a minimum distance of 5-10 cm. to all ow for cleaning behind the stove. The cl eanout
gate must be accessibl e.
Optimal combustion can only be obtai ned if fresh air i s constantly admitted. It is important,
therefore, to ensure that this i s the case.
The best way to provide a steady fl ow of fresh air i s by installing 1-2 air vent's) i n the room
where the stove is situated. (o ne in each side of the room).
Flooring:
If the floor on which the stove i s to be placed is i nflammable, the floor must be covered
with non-inflammable materi al, such as a steel or glass plate, floor tiles or arti ficial slate,
covering an area of at least 15 cm. from the sides of the stove a nd at least 30 cm. from the
front of it. With regard to the fro nt, however, we recommend 50 cm.
Also, the bearing constructio n must be capable of carryi ng 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 di ameter of at least 15 cm. T his corresponds to a clear of
175 square centimetres. Make s ure the chimney is of a suffici ent height, that it draws well
and that smoke does not bot her your neighbours.
We recommend that you fit yo ur chimney with a damper, all owing for draft control. This
may prove particularl y important on windy days.
Note: the damper must never s hut off draught completel y – always allow at l east 20
square cm free passage thro ugh the chimney.
With nominal usage the stove has tested a Smoke flow of 5,4 g/seco nd and with a smoke
temperature of 296° C i n a room of 20° C.
Varde stoves are always fi tted with a smoke pl ate which redirects smoke to make i ts way
to the chimney as effectivel y as possible. This e nsures that the heat from the smoke is
emitted inside your home rather t han outside it. The smoke pl ate is moveable and placed
on top of the Vermiculi te fire brick side plate. You should make s ure that it is pushed all
the way back against the back wal l of the combustion chamber.
How to light and stoke a fire:
The first time you light up the stove t he enamel will temper, and give off some smoke and
a slight smell. We recommend t hat you leave doors and wi ndows open, as airing the room
will make the smell di sappear. This tempering softens the e namel making it suscepti ble to
damage. Therefore exerci se caution and avoi d touching the enamel. Li kewise we recom-
mend opening the door to the stove at reg ular intervals for the first hours to prevent t he
insulation rope from sticki ng to the enamel.
Never use highly inflammabl e fluids such as spiri t and petrol for lighting up! Instead, use a
crumpled up piece of newspaper or ki ndling blocks topped by 10 -15 small sticks (c. 2 kg.).
A thin layer of ashes at the bottom of t he stove makes li ghting up a fire easier.
Before lighting up the stove, ope n the shaking grate by p ulli ng th e lever all the way out.
Then open the valve on the as h-pan for access of primary air and open the valve ab ove
the door for combustion air (al ternatively, shortly l eave the ash-pan a li ttle open if there is
no wind and no draught in the chimney), t hus all owing th e fire to catc h on. Always remem-
ber to close the ash-pa n again, otherwise the stove ca n be overheated, and this i s not
covered by the warranty.
When the fire burns steady, t hen remember to close the val ve on the ash-li d and also the
shaking grate again, so that t he combustion only gets primary -air through the li ttle hole in
the top of the valve.
Regulations
All local regulations as well as
National and European, sho uld be
adhered to when installi ng your
stove.
All Varde Ovne stoves are closed
fireplaces.
Draught conditi ons
Consult your local stove deal er about
how best to adjust the draug ht in your
chimney.
Chimney Fires
Should you r chimney catch fire, cut
off the air supply to the stove's
combustion chamber and contac t
the emergency services. ( The ma-
jority of fires die out afte r the oxygen
supply is cut off). Foll owing this, the
least you should do is to con tact
your chimney sw eeper, who will
check your stove and chimney for
damage.
Continual fresh air
A continual supply of fresh air is
required in the room in w itch the
stove is situated.
This can be achieved by instal ling 1
-2 vents, whilst al so ensuring that
these can not be bl ocked.
The shaking grate
The shaking grate is si tuated at the
bottom of the combustion chamber.
The ashes will be shaken into t he ash
-pan by the pulling and pus hing of the
lever.
Combustion / Seco ndary air
Pre-heated air for t he combus-
tion process, the amount of
which can be altered accordi ng
to the desired room tempera-
ture, and the effectiveness of
the chimney. A high level of
chimney draught requires a
lesser intake of combustion ai r.
VARDE OVNE A/S
Is a Danish company special is-
ing in functional, environmen-
tally friendly and designed
quality stoves.
As well as having passed the
Danish (DS/EN 13240 PLUS),
Swedish (SP), Norwegian
(Sintef) and German (DINplus)
Kite marks, the stoves is al so
awarded the coveted Svane-
maerke for environmentall y-
friendly products. (CO value o n
0,16 % and a smoke tempera-
ture of less than 300 °C).
Tertiary air
is constantly added air, whic h
makes the stove burn even
cleaner, and lowers the conte nt
of tar and soot in the combus-
tion process to an absolute
minimum.
At optimal combustion settings,
glass and combustion chamber
will be burnt completel y clean,
and the remaining amount of
ashes will be minimal .
What kind of wood t o use?
Generally, beech wood is co n-
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, birc h
and maple wood are fine alter-
natives.
Overheating
Occurs if too much wood is
placed in the stove or if the
combustion receives too muc h
air.
Vermiculite fire bri cks
A special non-inflammable
material. The vermiculi te fire
bricks both isolate and protect
the stove from attriti on. Vermicu-
lite fire bricks and smoke plate
are not covered by the warr anty.
Vermiculite is a very porous
material, therefore handle wi th
care. When refilling the stove,
put in the wood carefull y, use
the glove.
In most instances, however, yo u will have to arrive at the b est combustion air settings yo ur-
self, as the height and diameter of yo ur chimney, as well as the quality of the firewood are
decisive factors in determini ng how your particular stove i s best set (see also the secti on on
troubleshooting on next side).
If you are wondering why your stove i s fitted wi th an air beam with small holes in it, running
through the rear of the comb ustion chamber, this is merel y a consequence of our newl y devel-
oped combustion system. W e refer to these ai r ducts as the ‘tertiary ai r’, and will prove hel pful
as you install your new Varde stove.
When refilling the stove with wood, we r ecommend opening t he stove door only once embers
are left in the combustion chamber. Op ening the door whil st the flames are still burning and
producing smoke and gas, mi ght cause smoke to sli p into the room instead of up the chim ney.
What to burn
This Varde stove is tested a nd approved for the burning of wood. O nly dry wood with a moi s-
ture content of maximum 21 perce nt and the size to fit i nto the combustion chamber should be
used. The burning of moist wood wi ll result in an increased amo unt of tarry soot, pollution a nd
uneconomic fuel consumptio n. Newly chopped wood contai ns about 60-70 perce nt moisture,
which makes it completel y unsuitable as fuel. All ow newly chopped firewood to dry in an ope n
shed for a year before using i t in the stove. Split fi rewood with a diameter larger than 10 cm.
Use firewood with a length o n 25-30 cm.
The use of larger quantiti es of fuel than recommended in the tabl e page 2 will overtax the stove
and result in increased temperat ures in the chimney as well as a lowered efficiency. This may
cause damage to both chim ney and stove, and the annulment of the warra nty. Also, never use
toxic materials such as chipboard, pai nted or impregnated wood.
Maintenance a nd cleaning
As any piece of equipment i n daily use, your stove needs mai ntenance.
The stove should only be cl eaned when cold. Use a dry cl oth for cleaning the exterior of the
stove.
Clean the interior regularl y by removing ashes, soot and tar from t he combustion chamber. T he
smoke plate should be removed for cl eaning as the reverse si de will be covered in dirt and
soot. Finally check that the smoke's pat hway through the smoke pipe a nd chimney is com-
pletely clear. You should al so inspect the gaskets in the door and the as h-pan for si gns of
wear. Replace them if permeabl e. Also, remember to oil the hinges of the door as required.
Empty the ash-pan regularl y. It can be emptied i nto your dustbin, as long as you make sure i t
contains no hot embers.
When in doubt as how to clea n your stove, contact the dealer from whom yo u bought your
stove, or your chimney sweeper. It i s especially important to c heck the stove and its chimney
for blockages after a long peri od of non-use.
The enamelled surface of the stove may wear down at certain places if the stove is over-
heated.
Worn surfaces, however, ca n be repaired with a speci al Senotherm® spr ay paint, avail able at
your local vendor.
The plates in the combustio n chamber are Ver miculite plates and will eventuall y be worn – as
will the smoke plate. Should yo u accidentally break a pl ate, for instance by hitting it hard wi th a
piece of wood, this does not effect t he quality of the combusti on. You need not replace the
plate until the gap is 5 mm. wi de.
The door is constr ucted with a spri ng which a utomatically swings the door shut.
This may be a function required by e xisting regulati ons.
The springs is placed i n both hinges, and can be removed, i f you do not want this opti on.
Only use original s pare parts from V arde Ovne.
Do not make an y unauthorised cha nges.
All external parts of the stove becom e hot during use, too. Therefore ex ercise
necessary caution when the sto ve is in use.
Primary air valve
The valve on the ash-pan is for
access of lightening-air.
- When the valve is cl osed (the
small handl es is horizontal), then it
is in burning position. (the valve is
closed).
- When the valve is opened ( the
small handl es 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 val ve back to
burning position when the fire burns
steady.
