1. Before installing a new stove
All our products are tested according to the latest
European requirements and also to the Norwegian
standard NS 3058 and NS 3059, which include particle
tests. However, several European countries have local
regulations for installation of fireplaces, which change
regularly. It is the responsibility of the client that these
regulations are complied with in the country/region
where the fireplace is installed. Nordpeis AS is not
responsible for incorrect installation.
Important to check
(please note that this list is not exhaustive):
• distance from firebox to combustible/flammable
materials
• insulation materials/requirements between
fireplace surround and back wall
• size of floor plates in front of fireplace if required
• flue connection between firebox and chimney
• insulation requirements if flue passes through a
flammable wall
Chimney draught
Compared with older models, the clean burning stoves
of today put significantly higher demands on the
chimney. Even the best stove will not work properly
if the chimney does not have the right dimensions or
is not in good working order. The draught is mainly
controlled by gas temperature, outside temperature, air
supply as well as the height and inner diameter of the
chimney. The diameter of the chimney should never
be less than that of the flue/chimney collar. For draft
requirements at nominal heat output, see technical
table
The draught increases when:
• The chimney becomes warmer than the outside air
• The active length of the chimney over the hearth
increases
• There is good air supply to the combustion
It can be difficult to obtain the right draught conditions
in case the chimney is too large relative to the stove,
as the chimney does not heat up well enough. In
such cases you may want to contact professional for
evaluation of possible measures. Draught that is too
strong can be controlled with a damper. If necessary,
contact a chimney sweeper.
Air supply
A set for fresh air supply is available as accessory.
This will ensure that the air supply to the combustion
chamber is less affected by ventilation systems,
kitchen fans and other factors which can create a
down-draught in the room. In all new construction, we
strongly recommend that it is designed and prepared
for direct supply of outside air. In older houses, the use
of fresh air supply set is also recommended. Insufficient
air supply can cause down-draught and thereby low
combustion efficiency and the problems that this
entails: soot stains on the glass, inefficient use of the
wood and a soot deposits in the chimney.
For your own safety, comply with the assembly instructions.
All safety distances are minimum distances. Installation of the
stove must comply with the current rules and regulations of
the country where the product is installed. Nordpeis AS is not
responsible for wrongly assembled stoves.
The illustrations indicate the approximate centre height of
the recess for the flue. Consider possible inclination of the
flue prior to perforating the chimney. Distortions in floors
and walls may also influence the height. Place the stove
for accurate height and positioning of the flue/chimney
connection.
Subject to errors and changes.
For the latest updated version go to www.nordpeis.com.
2. Technical information
The stoves from Nordpeis all have secondary
combustion and are clean burning. The combustion
takes place in two phases: first the wood burns and
then the gases from the fumes are lit by the hot air.
This ensures that these new stoves have minimal
emissions of soot particles and un-burnt gases (such
as CO) and are thus better for the environment. Clean
burning stoves require a small amount of wood in order
to obtain a good heat output. Use exclusively clean and
dry wood. We recommend seasoned hardwood with a
maximum moisture content of 20%.

Duo 2: Two iron fasteners are screwed onto the pallet
and inserted through the back plate. Loosen these.
Next step is to remove the lower lid on the front of the
stove. It is fastened at the top with two clips at each
side. Pull the lid carefully outwards from the top and lift
it out of the two fasteners at the bottom. On the inside
of the lid there are two screws that must be unfastened
before the product can be removed from the pallet.
Duo 4/5/6: Open the door under the combustion
chamber. Unscrew the four screws that fasten the stove
to the pallet.

Duo 4/5/6:
NB! Please note that the legs of Duo 2, 4 and 5/6 must
be adjusted upwards, about 8 mm, if a form-fitted floor
plate is used. Please also note that the height of the
flue/chimney connection will also change if the product
is raised.
The CE mark should be placed to the
right in the chamber under the combustion chamber. FIG 14.
Assembly Duo 6 soapstone FIG 21-28
5. Lighting the fire for the first time
Duo 1: Does not have adjustable legs
When the stove is assembled and all instructions have
been observed, a fire can be lit.
Duo 2 FIG 5-6: In order to adjust the front legs;
Remove the lower lid in front by tilting it out of the clips
at the top (A) and lifting it out from the bottom (B).
In order to adjust the rear legs; Remove the back plate
as shown in FIG 8-10D.
Use a 17 mm wrench in order to adjust the legs.
Duo 4/5/6 FIG 7: Open the door to the space under the
combustion chamber. Remove the 4 plastic lids and
adjust the legs with a 17 mm wrench. Put the plastic lids
back in place.
Flue outlet collar
Duo is delivered standard with a top flue outlet
collar.
Take care when inserting logs into the burn chamber,
in order not to damage the Thermotte plates. Please
note that there might be some humidity in the insulation
plates which can result in a slower burn rate the first few
times the stove is used. These will be resolved once
the humidity has evaporated. Possibly leave the door
slightly open the first 2-3 times that the stove is used. It
is advisable to ventilate the room well when firing
for the first time as the varnish on the stove may
release some smoke or smell. Both the smoke and
smell will disappear and are not hazardous.
Lighting a fire
Insert small dry pieces of kindling wood, ignite and
ensure that the flames have established on the wood
before closing the door. Open the air vent control (FIG
4) before you close the door. Additional ignition air is
obtained by keeping the door slightly open. When the
flames are stable and the chimney is warm, the air
supply is regulated with the air vent control.
For rear connection
FIG 8-11: Remove the top plate (A). Unfasten the
two screws that holds the collar in place and remove
the collar (B). Unfasten the two screws and bracket
that hold the back plate in place (C-D). Use a Phillips
screwdriver in order tu unscrew the two screws that
keep the lid in place behind the back plate (E). Unscrew
the two screws that keep the lid in place over the flue
outlet and place the lid where the flue outlet collar was
before (FIG 11A-C). When the back plate is put back
in place it is important to push it well in place in order
to minimise the risk of gaps between the plate and the
sides of the stove.
When there is a glowing layer of ash, new wood logs
can be inserted. Pull the hot ember to the front of the
combustion chamber when inserting new logs so that
the wood is ignited from the front. Keep the door slightly
open each time new logs are inserted so that the flames
get established. The fire should burn with bright and
lively flames.
Connecting the flue
Please be aware when connecting the 150 mm flue to
the smoke dome that the flue is placed outside the flue
outlet collar. *Alternative versions exsists due to
National requirements. For the flue connection to the
chimney, follow the recommendations from the chimney
manufacturer
Using the stove with low combustion effect and firing
around the clock increase pollution as well as the risk
for a fire in the chimney. Never allow the stove or flue
to become glowing red. Turn off the air vent control
should this happen. Regulation of the air vent control
takes some experience, but after a little while a natural
rhythm for the fire will be found.
Air Supply
For connecting the fresh air supply set see FIG DUO
Air 1, 2 and 4/5/6.
Placement of CE mark
The CE-mark which is included should be placed on the
stove.
Duo 1:
The CE mark should be placed on the oblique surface behind the stove.
FIG 12.
Duo 2: The CE mark should be placed in the middle of the plate behind the lower lid in the front. FIG 13.
GB
IMPORTANT! Always remember to open the air
vent control and the door when new wood logs
are inserted into a hot burn chamber. Let the
flames get established on the wood before the air
supply is reduced.
When the draught in the chimney is low and
the vents are closed, the gas from the firewood
can be ignited with a bang. This can cause
damages to the product as well as the immediate
environment.

6. Maintenance
Cleaning and inspection
The stove should be inspected thoroughly and cleaned
at least once per season (possibly in combination
with the sweeping of the chimney and chimney pipes).
Ensure that all joints are tight and that the gaskets are
rightly positioned. Exchange any gaskets that are worn
or deformed.
Remember that the stove must always be cold when
inspected.
of clean and damp kitchen roll paper. NB! Only clean
when the glass is cold.
Check regularly that the transition between the glass
and the door is completely tight. Possibly tighten the
screws that hold the glass in place - but not too hard, as
this can cause the glass to crack.
Periodically, it may be necessary to change the gaskets
on the door to ensure that the burn chamber is air tight
and working optimally. These gaskets can be bought as
a set, usually including ceramic glue.
Ashes
The ashes should be removed at regular intervals.
Be aware that the ashes can contain hot ember even
several days after the fire is finished. Use a container
of non-combustible material to remove the ashes. It is
recommended to leave a layer of ashes in the bottom
as this further insulates the burn chamber. Take care
with the Thermotte plates when the ashes are removed,
particularly when using an ash shovel, so as not to
damage them.
Thermotte™ insulating plates
The insulating plates in the burn chamber (FIG 2)
contribute to a high combustion temperature, which
leads to cleaner combustion of the wood and a higher
rate of efficiency. Any fissures in the plates will not
reduce their insulation efficiency.
If new plates are needed, contact your dealer.

CERAMIC GLASS
CANNOT BE
RECYCLED
Ceramic glass should
be disposed of as residual waste, together with
pottery and porcelain
Recycling of the ceramic glass
Ceramic glass cannot be recycled. Old glass, breakage
or otherwise unusable ceramic glass, must be discarded
as residual waste. Ceramic glass has a higher melting
temperature, and can therefore not be recycled together
with glass. In case it would be mixed with ordinary
glass, it would damage the raw material and could, in
worst case end the recycling of glass. It is an important
contribution to the environment to ensure that ceramic
glass does not end up with the recycling of ordinary
glass.
Packaging recycle
The packaging accompanying the product should be
recycled according to national regulations.
7. Warranty
Please note: Wood logs that are too long can cause
strain and crack the plates, due to the tension created
between the side plates.
Please also note that the Thermotte plates may release
coloured dust when touched. Avoid touching any cast
iron parts with dust on your fingers. Any visible dust
on cast iron can be brushed off with the glove that is
included.
Door and glass
Should there be any soot on the glass it may be
necessary to clean it. Use dedicated glass cleaner,
as other detergents may damage the glass. (NB! Be
careful, even dedicated glass cleaner can damage the
varnish on the door frame). A good advice for cleaning
the glass is to use a damp cloth or kitchen roll paper
and apply some ash from the burn chamber. Rub
around the ash on the glass and finish off with a piece

8. Advice on lighting a fire
The best way to light a fire is with the use of lightening
briquettes and dry kindling wood. Newspapers cause a
lot of ash and the ink is damaging for the environment.
Advertising flyers, magazines, milk cartons and similar
are not suitable for lighting a fire. Good air supply is
important at ignition. When the flue is hot the draught
increases and door can be closed.
GB
Warning:
NEVER use impregnated wood, painted wood,
plywood, chipboard, rubbish, milk cartons,
printed material or similar. If any of these items
are used as fuel the warranty is invalid.
Warning: NEVER use a lighting fuel such as
petrol, karosine, alcohol or similar for lighting
a fire. This could cause injury to you as well
as damaging the product.
Use clean and dry wood with a maximum moisture
content of 20%. The wood should be dried for a
minimum of 6 months after it is cut. Humid wood
requires a lot of air for the combustion, as extra energy/
heat is required for drying the humid wood and the heat
effect is therefore minimal. This in addition creates soot
in the chimney with the risk of creosote and chimney
fire.
Common to these materials is that during
combustion they can form hydrochloric
acid and heavy metals that are harmful to
the environment, yourself and the insert.
Hydrochloric acid can also corrode the steel in
the chimney or masonry in a masonry chimney.
Also, avoid burning with bark, sawdust or other
extremely fine wood, apart from when lighting
a fire. This form of fuel can easily cause a
flashover that can lead to temperatures that are
too high.
Storing of wood
In order to ensure that the wood is dry, the tree should
be cut in winter and stored during the summer, covered
and in a location with adequate ventilation. The wood
pile must never be covered by a tarpaulin lying against
the ground as the tarpaulin will then act as a sealed lid
that will prevent the wood from drying. Always keep a
small amount of wood indoors for a few days before
use so that moisture in the surface of the wood can
evaporate.
Warning:
Make sure the insert is not overheated - it can
cause irreparable damage to the product. Such
damage is not covered by the warranty.

Usage
Not enough air to the combustion may cause the glass
to soot. Hence, supply the fire with air just after the
wood is added, so that the flames and gases in the
combustion chamber are properly burnt. Open the air
vent and have the door slightly ajar in order for the
flames to establish properly on the wood.
Note that the air supply for the combustion also can
be too large and cause an uncontrollable fire that very
quickly heats up the whole combustion chamber to an
extremely high temperature (when using with a closed
or nearly closed door). For this reason you should never
fill the combustion chamber completely with wood.
It is recommended to keep an even fire with a small
amount of wood. Too many logs put on hot ember, may
result in combustion air starvation, and the gases will
be released unburnt. For this reason it is important to
increase the air supply just after adding logs.
Choice of fuel
All types of wood, such as birch, beech, oak, elm, ash
and fruit trees, can be used as fuel in the insert. Wood
species have different degrees of density - the more
dense the wood is, the higher the energy value. Beech,
oak and birch has the highest density.
Attention! We do not recommend using fuel
briquettes/ compact wood in our products. Use of
such fuel may cause the product to overheat and
exceed the temperatures determined safe.
Burning briquettes/ compact wood is done so at
your own risk and only small amounts (max 1/3 of
normal load) should be used for each load.

Some advice in case of combustion problems
Error
Explanation
The chimney is blocked
No draught
The flue is sooty or there is accumulated soot on the
smoke baffle
Solution
Contact a chimney sweeper / dealer for more information or clean
the flue, smoke baffle and burn chamber.
The smoke baffle is wrongly positioned
Verify the assembly of the smoke baffle - see assembly instructions.
Downdraught in the room caused by no draught, that the
house is too “air tight”.
Light the fire with an open window. If this helps, more/bigger vents
must be installed in the room.
Downdraught in the room – caused by extractor and/or
central ventilation system that pulls too much air out of
the room.
Turn off/regulate extractor and/or other ventilation. If this helps,
more vents must be installed.
The flues from two fireplaces/stoves are connected to
the same chimney at the same height.
One flue must be repositioned. The height difference of the two flue
pipes must be of at least 30 cm.
The flue is in a declining position from the smoke dome
to the chimney.
The flue must be moved so that there is an inclination of at least
10º from smoke dome to chimney. Possibly install a smoke suction
device*.
The flue is too far into the chimney.
The flue must be reconnected so that it does not enter into the
chimney but ends 5 mm before the chimney inner wall. Possibly
install a smoke suction device*.
Soot hatch in the basement or attic that is open and thus
creating a false draught.
Soot hatches must always be closed. Hatches that are not tight or
are defected must be changed.
Damper/top draught vents or doors on fireplaces that are
not in use are open and create a false draught.
Close damper, doors and top draught vents on fireplaces that are
not in use.
An open hole in the chimney after that a fireplace has
been removed, thus creating a false draught.
Holes must be completely sealed off with masonry.
Defect masonry in the chimney, e.g. it is not airtight
around the flue pipe entry and/or broken partition inside
the chimney creating a false draught.
Seal and plaster all cracks and sites that are not tight.
The cross-section in the chimney is too large which
results in no or very low draught.
The chimney must be refitted, possibly install a smoke suction
device*.
The cross-section in the chimney is too small and the
chimney cannot carry out all the smoke.
Change to a smaller fireplace or build new chimney with a larger
cross section. Possibly install a smoke suction device*.
The chimney is too low and hence a poor draught.
Increase the height of the chimney and/or install a chimney cap/
smoke suction device*.
The chimney is too low in relationship to the surrounding
terrain, buildings, trees etc.
Increase the height of the chimney and/or install a chimney cap/
smoke suction device*.
Turbulence around the chimney due to the roof being
too flat.
Increase the height of the chimney and/or install a chimney cap/
smoke suction device*.
The combustion receives too much oxygen due to a
leakage under the lower border of the stove or too strong
chimney draught. Difficult to regulate the combustion and
the wood burn up too quickly.
Any possible leakage must be sealed off. A draught regulator or
possibly a damper can reduce the chimney draught. NB! A leakage
of only 5 cm2 is enough for 30% of the heated air to disappear.
The smoke buffer is wrongly positioned.
Verify the positioning of the smoke buffer – see assembly instructions.
In case of using oven-dried wood, this requires less air
supply than when using normal wood.
Turn down the air supply.
The gaskets around the door are worn and totally flat.
Replace the gaskets, contact your dealer.
The chimney is too large.
Contact chimneysweeper or other professional for more details.
The wood is too wet.
Only use dry wood with a humidity of maximum 20%.
The air vent control is closed too tightly.
Open the air vent control to add air to the combustion. When new
wood logs are inserted all vent controls should be completely
opened or the door slightly opened until the flames have a good
take on the wood.
Bad combustion (the temperature is too low)
Follow the guidelines in this user guide for correct combustion.
White glass
Using wrong material for combustion (such as: painted
or impregnated wood, plastic laminate, plywood etc)
Ensure to use only dry and clean wood.
Smoke is
