Installing the stove:

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

distances (in centimetres) to inflammable walls and materials:

In-Line 47: Sides: 30 cm Rear: 30 cm Distance to furniture in front of stove: 105 cm

In-Line 55: Sides: 35 cm Rear: 35 cm Distance to furniture in front of stove: 110 cm

Both stoves must be placed with this minimum distance to the floor: 30 cm

If walls are non-inflammable, the stove can be placed closer to them. However, we recom-

mend a minimum distance of 2-10 cm.

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 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. Read the table on page 4, to find out how much your stove weights.

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 valve under the door for combustion air.

After lightening the fire, you can ad extra oxygen by opening the door a little bit, (the door

handle has 2 steps: In step 1 the door is closed and in burning positing. In step 2 the door

is a little bit opened and in lighting position).

When the fire burns steady, then always remember to close the door again, otherwise the

stove can be overheated, and this is not covered 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.

Combustion / 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.

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 PLUS),

Swedish (SP) and Norwegian

(Sintef) Kite marks, the stoves is

also awarded the coveted

Svanemaerke for environmen-

tally-friendly products. (CO value

on less than 0,20 % and a

smoke temperature of less than

275 °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 air beam with small holes in it, running

through the rear of the combustion chamber, this is merely a consequence of our newly devel-

oped 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 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.

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.

Do you have a question about the VARDE OVNE IN-LINE 47 and is the answer not in the manual?

This document describes the Varde In-Line 47 and Varde In-Line 55 stoves, which are designed for intermittent combustion and approved according to DS/EN 13240 standards. These stoves are closed fireplaces and can be connected to a chimney used by other fireplaces, provided appropriate rules and regulations are followed.

Function Description

The Varde In-Line stoves are designed to provide efficient and environmentally friendly heating. They utilize a combustion system that includes "tertiary air," which is constantly added to make the stove burn cleaner and minimize tar and soot content in the combustion process. At optimal combustion settings, the glass and combustion chamber will burn completely clean, leaving minimal ashes. The stoves are also fitted with a smoke plate that redirects smoke to maximize heat emission inside the home. This smoke plate is movable and positioned on top of the Vermiculite fire brick side plate, and should be pushed back against the combustion chamber's rear wall.

The stoves are designed to operate with a continuous supply of fresh air in the room, which can be achieved by installing 1-2 vents and ensuring they are not blocked. Pre-heated air is supplied for the combustion process, and its amount can be adjusted based on the desired room temperature and chimney effectiveness. A high level of chimney draught requires a lesser intake of combustion air.

Usage Features

Lighting and Stoking:

First Use: The enamel will temper, emitting some smoke and a slight smell. Air the room by opening doors and windows. The tempering softens the enamel, making it susceptible to damage; handle with caution and avoid touching. Open the stove door at regular intervals for the first hours to prevent the insulation rope from sticking.
Fuel: Do not use highly inflammable fluids (spirit, petrol). Instead, use crumpled newspaper or kindling blocks topped by 10-15 small sticks (approx. 2 kg). A thin layer of ashes at the bottom makes lighting easier.
Combustion Air: Open the valve under the door for combustion air before lighting.
Adding Oxygen: After lighting, open the door a little bit (door handle has 2 steps: step 1 is closed/burning, step 2 is slightly opened/lighting position).
Closing the Door: Once the fire burns steadily, close the door. Overheating can occur if left open, which is not covered by the warranty.

Recommended Fuel: Only dry wood with a moisture content of maximum 21% and sized to fit the combustion chamber should be used. Moist wood causes increased tarry soot, pollution, and uneconomic fuel consumption. Newly chopped wood (60-70% moisture) is unsuitable; allow it to dry in an open shed for a year. Split firewood with a diameter larger than 10 cm. Use firewood with a length of 20-25 cm.

Best Wood Types: Beech wood is considered ideal, burning evenly without much smoke and leaving clean, minimal ashes. Ash, birch, and maple wood are fine alternatives.

Overheating: Occurs if too much wood is placed in the stove or if the combustion receives too much air. Using larger quantities of fuel than recommended will overtax the stove, increasing chimney temperatures and lowering efficiency, potentially damaging both chimney and stove, and annulling the warranty. Never use toxic materials such as chipboard, painted, or impregnated wood.

Vermiculite Fire Bricks: These are special non-inflammable, porous materials that isolate and protect the stove from attrition. They are not covered by the warranty. Handle with care; when refilling, put wood in carefully and use a glove. If a plate breaks (e.g., by hitting it hard with wood), it does not affect combustion quality. Replacement is only needed if the gap is 5 mm wide.
