Installing the stove:
According to existing regulations, stoves must be placed with the following minimum
distances (in centimetres) to inflammable walls and materials:
Sides:
25 cm
Rear:
20 cm
Distance to furniture in front of stove:
75 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 Farsø 1 is:
73 kg.
The weight of Farsø 4 is:
70 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.
With nominal usage the stove has tested a Smoke flow of 3,6 g/second and with a smoke
temperature of 241° 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 door for access of
primary air
and pull out the valve above
the door 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 remem-
ber to close the door again, otherwise the stove can be overheated, and this is not cov-
ered by the warranty.
When the fire burns steady, then remember to close the valve on the door again, until its
½ mm open.
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.
VARDE OVNE A/S
Is a Danish company specialis-
ing in functional, environmen-
tally friendly and designed
quality stoves.
The stove has passed the Dan-
ish (DS/EN 13240), Swedish
(SP), and German (DIN) Kite
marks, with following results:
(CO value on 0,15 % and a
smoke temperature of less than
250 °C).
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
your-
self, 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
troubleshooting 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 21 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 20-25 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 com-
pletely 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
over-
heated.
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
Also known as ´sub-air´, the air which
is drawn into the combustion cham-
ber through the air valve on the door.
