General safety instructions for the
operation of your stove
•Thoroughly read the entire manual before starting up
your stove and observe the caution notices.
•Your heating unit may not be moved without approved
means of transport with sufficient load-bearing capacity.
•Your heating unit is not suitable to be used as a stand or
as a ladder.
•Please keep in mind that your
stove’s surface heats up considerably
during operation. We therefore
recommend wearing a safety mitten
when operating your stove.
•Attention – stove varnish is no rust prevention!
•Make your children aware of this particular danger and
keep them at a distance from the heating unit whenever it is
in operation.
•Only burn approved fuels and materials listed in the
chapter “Clean Burning”.
•The burning or placing of flammable or explosive
materials, like empty spray cans and such like into the
firebox as well as the storage of such materials in the
immediate vicinity of your heating unit is strictly forbidden
due the danger of explosion.
•Do not wear loose or flammable clothing when adding
fuel to the fire.
•Placing non-heat-resistant objects on the heating unit or
in the vicinity of the heating unit is forbidden.
•Do not lay laundry onto the stove for drying. Laundry
hung up to dry must be kept at a safe distance from the
stove because of the danger of fire.
•The woodstove DEXTER is no “slow combustion stove”
(must hold embers for at least 4 hours).
•During the operation of your heating unit it is forbidden to
use flammable or explosive materials in the same or an
adjacent room to the one in which your heating unit is
located.
•The appliance must be operated with the stove door
closed.
•The stove door and all fittings for adjusting the stove
must be closed, if the appliance is out of use.

Combustion air
Being the user of the stove you must take care of a sufficient combustion air supply. Sealed-up windows and doors may not allow a
sufficient combustion air supply or disturb the draught behaviour of your stove. Please ensure the additional supply of fresh
combustion air if necessary. For details please consult your specialist retailer. Make sure that the combustion air intakes are not
blocked!
Stove pipe connection
For your own safety stringent laws apply for connecting stove pipes to the chimney. Your professional dealer or distributor
knows these laws. Please have your certified retailer carry out the connection of your stove.
Floor load capacity and Hearth
Make sure that the load capacity of the supporting construction is sufficient to carry the weight of the entire unit, before the
heating unit is installed.
The hearth requirement is minimum 820mm deep x 1120mm wide x 9mm thick fibre cement sheet (Bellis board or similar, with
minimum of 300mm in front of 2 sides of glass.
Flue Connection to Heater
The flue collar fitted to the unit is 5” – Inner diameter is tapered from 137mm and outer diameter is 148mm.
The top flue connection requires either a 5” to 6” adaptor to fit within the top box, or the Austroflamm Flue damper (fits to the
outside of the flue collar (ensure the connection is sealed with fire cement on the inside).
If using the flue damper inside the top box, ensure the damper is set to 30 degrees from the horizontal (assuming a 4.6m
flue height from the hearth).
For rear connection, the rear flue blanking plate is swapped with the flue collar supplied on top of the firebox. Use the top
box with blanking cover to cover the unit. Using the 5’ to 6” adaptor into the flue collar, have holes drilled through the cast
flue collar into the stainless steel active so the flue is mechanically fixed, and seal with fire cement. Connect to a wall
penetration kit or a drop box with triple skin T-piece and flue as per normal with rear wall flue installation. See pics on page
8.

3. CORRECT OPERATION OF YOUR STOVE
Approved fuels
Dry, well cured and natural wood (hardwood preferred),
wood briquettes.
Maximum amount of fuel
Maximum amount of fuel to be added: 1,4 kg wood. Larger
amounts of fuel can lead to overheating and thus damage
the stove.
Clean burning
The wood must be dry (relative wood moisture < 15%) and
untreated and the right amount of wood must be burned in
order to ensure a clean fire that releases only small
amounts of emissions.
Startup procedures
During the first 3-4 operations - at nominal heat output -
there may be some odour development and the varnish has
not yet hardened.
Making a fire
For the correct and safe operation of your stove please pay
attention of the chimney developing the necessary feed
pressure. This must especially be considered before the
initial operation (or e.g. after the summer heating break) and
during the mid-season heating periods (e.g. at strong wind,
etc.).
If there is not enough feed pressure, please light only some
paper or small kindling first, in order to “warm up” the stove
and the chimney.
The air inlet must not be covered or closed.
Clean grate, empty ash drawer if necessary (watch out for
ambers!).
Position the lever for the combustion air to the open (“AUF”)
position (see fig. 4).
Place 2-3 logs (approx. 1,0 kg in total) crossways in the
combustion chamber (1) with sufficient distance from each
other (min. 2 cm), on top of that place some softwood
chippings (0,4 kg) (2) and some ignition aid and light (3).
(see fig. 3)
Close the door!
We recommend to let the first load burn down without
changing the air lever position.
As soon as no visible flames are left (only embers left in the
combustion chamber), you can put another load of logs
(approx. 1,4 kg) in the combustion chamber if desired.
When reloading the stove please repeat the procedure as
mentioned under “first lighting”: air lever position on “AUF”
(= open), open door carefully, place logs, close door.
Fig. 4: air knob
After a few minutes, when the logs burn well on all sides
(bright, high flames - see fig. 5), you can adjust the heat
output with the air lever (lever on max. position “AUF” =
maximum heat output), the flames should be yellow and
never look blueish or have black tips (otherwise add more
air) – see fig. 4. Never close air supply completely during
operation. Danger of flash-fire!
The stove door may be opened only for refuelling or
disposing of ashes and is to be closed again afterwards.

Heating in-between seasons
Heating the stove in between seasons, when the outside
temperatures are higher, the flue gases may not be able to
escape completely and this may lead to disturbances in the
chimney draught, especially if the temperatures are rising
suddenly. The stove has to be charged with less wood and
the primary air has to be increased so that the wood can
burn down faster (with visible flames) and thus the chimney
flue can stabilize.
Chimney fire
A chimney fire may occur, due to sooting and deposits in the
chimney, if impropes or humid fuel is used. In case of a
chimney fire close all air inlets on the fireplace/chimney
immediately and call the fire brigade. Please have an expert
inspect your chimney for cracks and air-tightness after the
burning out of the chimney.

Accessories
You can obtain floor plates made of glass or steel, care products or the Heat Memory System for heat storage from your
certified dealer.
IMPORTANT: Have defective parts replaced by your certified dealer. This will guarantee that your stove functions
properly and safely.
The fireplae must not be altered.
Maintenance
To clean the glass, please use a specialised product such as Thermohit glass cleaner. Lacquered surfaces are to be
cleaned only with a cloth (may be damp). Special cleaning agents should also be used for stainless steel surfaces.
Only gaskets in good order ensure the proper function of your stove!
Cleaning
The stove, flue outlets and smoke pipes should be cleaned and inspected for deposits every year – if necessary more often,
e.g. after the cleaning of the chimney. The chimney also has to be cleaned regularly by the chimneysweeper. Your
chimneysweeper will inform you of the necessary inspection intervals. An expert should inspect the stove annually.
