First, we would like to congratulate you on becoming a happy owner of a Viking wood burning
range, made in Austria with highest quality materials.
Your new wood burning range is both a meless and eecve heat source with more than 100
years of development and history. The Viking range is equipped with the latest combuson
technology to provide maximum heat output and minimal environmental impact. We hope
you will enjoy many cosy days with your new range and benet greatly from it in the future.
However, remember to read the installaon and maintenance manual carefully before
commencing assembly and before pung the range to use.
Warm regards,
Josef Davidssons

The manual contains instrucons on how to mount and
install the Viking 40. To ensure the funcon and safety
of the range, we recommend that installaon be carried
out by a professional. Contact one of our dealers who

When installing a replace and erecng a chimney,
a building applicaon must be submied to the
municipality's building commiee. Contact your building
commiee if you are unsure of how the applicaon
works.

Make sure that the ground oor in your home has
sucient bearing capacity for a wood burning range with
a chimney. Normally, a wood burning range and chimney
can be placed on a standard wooden frame in a single-
family house if the total weight does not exceed 400 kg.
Hearthstone
Ember coming from the range poses a risk of re. If you
have a ammable oor in front of your wood burning
range, it must be protected by a hearthstone that covers
at least 300 mm in front of the door and 100 mm along
each side. The hearthstone can consist of, for example,
natural stone, concrete, sheet metal or glass.
The specied safety distances in this manual apply to the
Swedish market. If the wood burning range is installed in
another country, the local regulaons must be met.

When burning, some areas of the wood burning range become very hot and can cause burns when
touched. Also, be careful with heat radiang through the door glass. If combusble material is placed
closer than the specied safety distance, it can quickly catch re. Smouldering combuson can cause
rapid gas ignion with the risk of injury to persons and property.

The installaon must be inspected by a competent
chimney sweeper before using the range.
Approved for connecng to the chimney with 1/2
stone enclosure (350°). Mulple use (connecon to
common chimney) is allowed as long as respecve local
regulaons are adhered to.

Viking 40 is made in Austria with a tradion dang back
to the 1930s. The range consists of high quality steel
with cast iron doors. The combuson chamber is lined
with chamoe stone, and a cast iron grid forms the
replace base.
The range is equipped with an upper of steel or glass
ceramic (oponal) that serves as a single large cooker /
hot plate. The basic structure of the range consists of
machine-welded sheet metal plates to which external
plates are screwed. The replace door is equipped with
a double, air-polished ceramic hardened glass that allows
for a wonderful and soot-free view of the re. Maximum
heat output and low wood consumpon are obtained
due to the fact that the hearth and gaps are equipped
with a reproof sealant, and by burning the wood under
automac supply of preheated secondary air through the
holes in the hearth’s back plate. Primary air is supplied
above the door glass.
Chimney
The ue diameter should be at least 125 mm, have a
chimney dra of at least 0.12 mbar and a recommended
minimum height of 3.5 m on the ue (calculated from the
replace's connecon).
Adjustable cooking height
The total height of the hearth is adjustable between
850-920 mm. Li up the hearth in the front so that the
hearth rests on the rear adjusng screws to more easily
adjust the front adjusng screws and vice versa. The four
adjusng screws have a M10 thread with a key width of
17 mm.

When mounng close to ammable components, re-

In addion to radiang heat, the Viking 40 is also
equipped with convecon technology. This means that
the cool room air is sucked into the sides of the wood
burning range, heated, pushed out through the oval holes
on the hob and nally ows into the room. This allows
the hot air to spread more easily around the room.

The primary air is supplied when the glass door of
the range is le half-open during the lling up of
rewood and during the ignion phase. Secondary
air is supplied through the buery valve under the
range. The secondary air is then heated in the range and
disseminates into the re through the holes in the range’s
back plate.

The wood burning range meets the requirements for
connecon to a chimney designed for 350°C smoke
temperature.
The adapter measures 120 mm on the outside; applicable
with both rear and side connecon.
The opmum chimney dra is between -10 to -15 Pa.
The dra is mainly aected by the length and area of
the chimney, but also by how pressure-ght it is. The
minimum recommended chimney length is 3.5 m, and
the appropriate cross seconal area is 120-180 cm² (125
mm in diameter).
A ue with narrow bends and horizontal draught reduces
the dra in the chimney. The maximum horizontal ue is
500 mm, provided that the vercal ue length is at least
5 m.
It should be possible to sweep the ue throughout its
length, and the soot doors must be easily accessible.
Check that the chimney is sealed and that no leakage
occurs near the soot doors and smoke connecons.
The range can be connected to the chimney with several
replaces.

Carefully open a hole in the spot where you will
connect your wood burning range to the chimney
stack.

MAINTENANCE
The grid should be shaken and cleaned from ashes
regularly.
Empty the ash pan as soon as it is full.
Aer a period of burning, some soot may have seled on
the glass. With the Sotrent dry sponge you can keep the
glass clean easily.
Keep the hearth and ue clean. If you use the range
oen, you should sweep the chimney every once in a
while in between the visits of the chimney sweeper.
Exterior of the range
The enamelled surfaces are cleaned with lukewarm
water when the range is cold. Under no circumstances
may abrasives, scraping or scouring detergents or objects
be used.

For cleaning and care of precious steel parts (stainless
steel, etc.), only the special products that are
commercially available should be used.
Steel hob
The hob is face grinded and oiled on delivery to prevent
rusng. The oil evaporates at the rst use and may
smoke a bit. The heat will make the steel hob darken, and
aer a while it will obtain an evenly dark colour. You can
use a sponge or a scraper if something has boiled over,
for example.
Ceramic hob
The ceramic hob is mechanically very stable and can
easily withstand medium impact bumps. If cracks or
scratches should occur due to mechanical impact, the
use of the range must be immediately disconnued.
The ceramic hob has to be replaced with a new one.
However, if the glass ceramic hob breaks due to improper
handling during use, the break should be covered with
the ash / soot collectors unl the range has cooled down.
The ceramic hobs are cleaned with the same detergent
that are used on the glass hob on an electric stove.

A new wood burning range should be red with care
during the rst few occasions. That makes the heat-
resistant colour more durable. There may also be a
slightly unpleasant smell at the rst ring. This is normal
and due to the fact of excess paint or oil coang remains
on the range. The smell will disappear at the rst ring
and will not return.
Firewood
The best heat value is obtained from split birch wood.
Leafy trees generally burn calmer than conifer wood,
which creates a more even heat. If you are burning
oak, beech or other wood with high heat value, always
mix the wood with other wood. Otherwise you risk
damaging your hearth. The wood must be dry, with
preferably 15-20% moisture content. With a normal re,
approximately 1.5-2 kg wood / hour is a suitable amount
of wood. 1 kg birch wood produces about 4 kW power.

Fully open the supply air valve (buery valve under the
range door). Place briquees in the centre of the hearth.
Pile up about 1.5 kg of small wood logs crosswise, like a
log house, on top of the briquees. Start by lighng the
briquees. These should in turn ignite the wood. Keep
the hearth door open during the rst few minutes unl
the wood is properly ignited. Depending on the chimney
dra, you may need to have to leave the door open
slightly longer to build a temperature in the hearth and
get a sasfactory chimney dra. Then close the door
and adjust the valve to the desired intensity of the re.
The range should be properly heated before starng to
reduce the air supply.

When the intensity of the re has decreased, it is me to
replenish. Open the door carefully. That way, you avoid
smoke gusts. Use a replace tool or a piece of wood
to distribute ash and glow. Replenish with 2-4 logs and
close the door when the wood has ignited properly (1.5-2
kg wood). Firewood should only be relled when there is
only embers in the combuson chamber (no ames). Aer
the fuel rell, the hearth door must be kept half-open
unl the wood has ignited properly.

Make sure the logs don’t get too close to the door.
Otherwise, ember and ashes may fall out when the door
is opened.

In order to kindle the re correctly, it is necessary
to achieve as high a temperature as possible in the
hearth. Then you’ll have a clean combuson and get
the most out of the range and the rewood. With clean
combuson, you avoid soot coang in the hearth and
on the glass. When used correctly, the smoke will not be
visible when the range has heated up.

For operaon during seasonal change, that is, at higher
ambient temperatures than 15°C, the sudden change
in outdoor temperature can change the pressure in the
ue gas sha, so that the combuson gases are not
completely discharged. The range should then be lled
with less rewood at a me and have the buery valve
open (posion 1) so that the fuel burns faster and thus
stabilizes the outlet pressure.
