Installing the stove:

According to existing regulations, stoves must be placed with the following minimum dis-

tances (in centimetres) to inflammable walls and materials:

Sides: 25 cm Rear: 10 cm Distance to furniture in front of stove: 80 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, 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.

Find the weight of the stoves on page 4.

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 4,8 g/second and with a smoke

temperature of 304° 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 ignition air and open the valve on top on

the Stove 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 ignition air valve on the ash-lid

again, (the handle is in vertical position). When the stove is burning nominal, there may not

be added air through this valve, it may cause overheating of the stove, and this is not cov-

ered by the warranty.

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.

As well as having passed the

Danish (DS/EN 13240),

Swedish (SP), Norwegian

(Sintef) and German (DINplus)

Kite marks, the stove is also

awarded the coveted Svane-

maerke for environmentally-

friendly products.

(CO value lower than 0,12 %

and a smoke temperature of

less than 305 °C).

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 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).

If you are wondering why your stove is fitted with an gap in the rear vermiculite plate in the

combustion chamber, with small holes through the back steel plate, where air is running

through into the combustion chamber. This is merely a consequence of our newly developed

combustion system. We refer to these air ducts as the ‘tertiary air’, and will prove helpful as

you install your new Varde stove.

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 couple of years 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

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 spring is placed behind the left steel-sideplate, 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.

Ignition air valve

The valve on the ash-pan is con-

structed as a ignition air valve, and

may only be used when lighting up

the stove. When the stove is burning

the valve has to be closed again.

- The valve is closed (burning posi-

tion) when the handle on the valve is

standing in vertical position.

- The valve is opened (ignition

position), when the handle is in

horizontal position and the hole in

the valve is in the topside.

Remember to turn the valve back to

burning position when the fire burns

steady.
