I portant!
Before lighting up your Varde Stove for the
first time, we recommend that you read these
instructions carefully and contact your local
stove vendor or building authoorities to inquire
about existing regulations regarding the
intallation of stoves. Please follow these
regulations closely.
Inspection of installation
It is very important that the installation be
inspected by a qualified chimney sweeper
before the stove is in used for the first time.
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.
The stove is designed for intermittent
combustion and can be connected to a
chimney used by other fireplaces, as long as
the appropriate rules and regulations are
adhered to.
This Varde Stove
Has passed the
anish /European Standard S/EN 13240
and the German ( INplus) test , and have
thereby proved to be a environmentally friendly
product.
Proffesional installation
We recommend that you consult with the
dealer where you purchased the stove or an
other competent installer, as there may be
specific things to consider during the
installation. You should also reseive the
applicable rules for installing the stove and
follow them.
Please Note!
You are by law required to register your stove at the local chimney-sweeper.
Until installation keep the stove dry and not to cold. The stove cannot stand moisture.
That an existing chimney, not necessarily is effective enough for a new modern stove.
Vermiculite is a very porous material, therefore handle with care. When refilling the stove, put
the wood carefully, use the glove.

Flooring:
If the floor on which the stove is to be placed is inflammable, the floor must be covered with non
-flammable material, such as steel or glass plate, floor tiles or artifical 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. Regarding the
front, however, we recommend 50 cm. Also, the Floor construction must be capable of carrying
the combined weight of stove and chimney.
Installation distance:
If walls are non-inflammable, the stove can be placed closer to them. However, we recommend
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).
According to existing regulations, stoves must be placed with the following minimum distances
in mm to inflammable walls and materials. The distance from the outer edge of the flue pipe to
inflammable material is descriped as for horizontal Flue 300mm and the distance for vertical flue
is 225mm

The chi ney:
Always use a chimney with a diameter of at least 15 cm. This corresponds to a clear of 175 cm
2
.
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 cm² free
passage through the chimney.
With nominal usage the stove has tested a flue gas flow of 4,9 g/second and with a flue gas
temperature of 265 °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 Ver-
miculite fire brick side plate. You should make sure that it is pushed all the way back against the
back wall of the combustion chamber.
Draught conditions
Consult your local stove dealer about how best to adjust the draught in your chimney.
Hight of chi ney
If in doubt, contact your local stove dealer. He will be able to inform you of the correct hight.
Connection of Flue pipe:
Infor ation about the new cast iron adapter, Part no.: 134
Your stove is equipped with the new cast iron adapter from Varde Ovne.
The adapter is suitable for smoke pipes with inner diameter on 150 mm.
If you need it, it’s now possible for you to make a condensate drain-hole in the adapter.
♦ Carefully punch a chisel or the like through the adapter in the outer groove, at the arrow
mark. This way you can establish a condensate drain hole in the adapter.
Arrow mark for the hole. Now the condensate – hole is
ready.
Carefully punch a hole with a
chisel or the like.

Co bustion/Secondary air
Pre-heated air for the combustion process, the amount of which can be altered according to the
desired room temperature, and the effectiveness of the chimney. A high level of chimney
draught requires a lesser intake of combustion air.
Pri ary air
Also known as ´sub-air´, the air which is drawn into the combustion chamber through the air
valve on the ash pan.
Continual fresh air
A continual supply of fresh air is required in the room in wich the stove is situated. This can be
achieved by installing 1-2 vents, whilst also ensurring that these can not be blocked. The
quantity of air used for burning, is approx. 15,5 m³ / h.
Overheating
Occurs if too much wood is placed in the stove or if the combustion receives too much air.
The Shake grate
The shaking grate is sittuated at the
bottom of the combustions chamber. The
ashes will be shaken into the ashpan by
pulling and pushing of the lever.

Ver iculite
The plates in the co bustion cha ber are Ver iculite plates and will aventually be worn,
- as will the smoke plate. Should you accidentally breah the 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.
Ver iculite
A special non-flammable material. The vermiculite fire plates both isolate and protect the stove
from attrition. Vermiculite plates and deflector not covered by the warranty. Vermiculite is a
very porous material, therefore handle with care. When refilling the stove, put the wood
carefully, use the glove.
How too replace the Ver iculite
1. eflector, lift easily, bottom bag end are tilted forward, take down.
2. The left side plate can be easily liftes up and rotated out.
3. Right side plate can be easily lifted up and rotated out.
4. The back cover is liftes up and out of the stove.
Mounting of new Vermiculite plates follow point 4 towards point 1.

The new stove
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 recommend opening the door to
the stove at regular intervals for the first
hours to prevent the insulations rope from
sticking to the enamel.
What kind of wood to use?
Generally, beech wood is considered the best
type of wood for burning. It burns evenly
without producing much smoke and ashes are
clean and take up little space. Ash, birch and
maple wood are fine alternatives.
How big the firewood?
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 tabel belove will overtax
the stove and resulte 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.

The following optimal register and fuel quanitty settings are recommended(in case of similar chimney
draught):
What to burn.
This Varde Stove is tested and approved for
the burning of wood. Only dry wood with a
moisture 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
chooped firewood to dry in a open shed for a
couple of years before using it in the stove.
Do not use! - Consider the environ ent
Also, never use toxic materials such as
chipboard, painted or impregnated wood.
The use of larger quantities of fuel than
recommended in the tabel belove will overtax
the stove and resulte 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.
Topdown Lightning of the fire

13
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 exeercise caution and avoid touching the enamel. Likewise we recommend opening
the door to the stove at regular intervals for the first hours to prevent the insulations rope from
sticking to the enamel.
Never use highly inflammable fluids such as sprit and petrol for lighting up!
We recommend a ”Top- own” lightning, where you light the wood in the upper area of the
combustions chamber and not in the ground. This method is the most environmental metod to
light a fire. The metod will keep the glass clean. In the combustion chamber you make a cross
(╬) of 4 small pieces of wood with a small distance between each one of them. On top you of
them you make another cross (╬) of 8-12 smaller sticks (0,5-1 kg.), on top of this firewood and
in between use 2-3 kildning blocks. A thin layer of ashes at the bottom of the stove makes light-
ing up a fire easier.
Before lighting up the stove, open the Shake grate by pulling the lever all the way out.
Then open the valve on the ash-pan for access of pri ary 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 overheadted, 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 approx. 10 % open.
In most instances, however, you will have to achieve the best co bustion air settings your-
self, as the height and draught of your chimney, as well as the quality of the firewood are deci-
sive factors in determining how your particular stove is best set.
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 slip into the room instead of up the chimney.

14
Maintenance:
As any piece of equipment in daily use, your stove needs maintenance.
The stoves should only be cleaned when cold. Use a dry cloth for cleaning the exterior of the
stove.
Clean the interior regulary by removing ashes, soot and tar from the combustion chamber. The
eflector should be removed for cleaning as the reverse side will be covered in dirt and soot.
Finally check that the smoke pathway thhrough the smoke pipe and chimney is completely 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 regulary. 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 blokages after a long period of
non-use.
The ena elled 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 co bustion cha ber are Ver iculite plates and will aventually be worn,
- as will the smoke plate. Should you accidentally breah the plate, for instance by hitting it hard
with a piece of wood, this does not effect the quality of the combustion. You do not need to
replace the plate until the gap is 5 mm wide.
Only use original parts fro Varde Ovne A/S
Do not ake any unauthorised changes.
All external parts of the stove beco e hot during use, too. Therefore exercise
necessary caution when the stove is in use.
IMPORTANT!!
Chi ney Fires
Should your chimney catch fire, cut off the air supply to the stove’s combustion chamber and
contact the emergency service. (The majority 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.

Troubleshooting.
S oke enters the roo :
• Not enough draugh in the chimney.
• Inspect the smoke pipe or the chimney for blockage.
• Clean the inside of the stove removing soot from the upper vermiculite / smoke
( eflector) plate.
• Make sure the hight of the chimney is correct.
The glass or the chi ney 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 ignition air too aerly when lightning up the stove.
• There always have to be clear flames in the combustion chamber.
The heat is e itted fro 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.
• The amount of combustion(secondary air) air is not enough.
Co bustion is too intense:
• Gaskets in the door or the ash-pan are no longer tight and need replacement.
• The chimney draugh is too strong—apply a valve in the chimney.
• Inspect that the ignition air is closed.
The Shake grate is stuck:
• Inspect the grate for jammed wood, nails or the like.
• Make sure the lever is placed correctly .
