VARDE OVNE Varde Cast Iron S1 Installation And User Manual

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: 30 cm Rear: 15 cm Distance to furniture in front of stove:
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 stove Varde S1 is to be placed on a floor witch is inflammable, the floor must be cov-
ered 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.
If the stove Varde S3 (low feet) is to be placed on a non-inflammable bench witch min. is 27
cm. high, an inflammable floor around the bench has to be covered the same way as for
Varde S1.
If the stove Varde S3 (low feet) is to be placed directly on the floor, the floor has to be made
of non-inflammable materials under the stove, as well as 15 cm. on the sides and 50 cm. in
front of the stove.
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
centimetres free passage through the chimney.
With nominal usage the stove has tested a Smoke flow of 6,0 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.
Lighting for the first time:
The first time that the stove is lit, lighting should be terminated after the initial fire has
caught. This is so that the cement that is used as sealant is able to harden, after that the
stove can be used according to the following instructions.
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 dam-
age. 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 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 a lot easier.
Before lighting up the stove, you have to open completely for the combustion air
(Secondary air) by pushing the grip under the door to the right side, (alternatively, shortly
leave the door a little 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 after some minutes, otherwise
the stove and the chimney can be overheated, and this is not covered by the warranty.
By lighting up we recommend to let the secondary air fully open all the time, this to warm up
the stove and chimney to appropriate working temperature.
Once the wood has burnt to embers, you may refill the stove with the next lot of wood, once
again having the damper fully open until the wood is burning well, then adjust it to the below
described positions.
The following optimal register and fuel quantity settings are recommended (in case of similar chimney draught):

Draught conditions
Consult your local stove dealer or
chimney sweeper 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 com-
bustion chamber and contact the
emergency services.
(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.
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 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.
Overheating
Occurs if too much wood is placed
in the stove or if the combustion

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.
