INDEX 1. Prior to assembling the insert
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 replaces, which change
regularly. It is the responsibility of the client that these
regulations are complied with in the country/region
where the replace is installed. Nordpeis AS is not
responsible for incorrect installation.
Important to check
(please note that this list is not exhaustive)
• distance from rebox to combustible/ammable
materials
• insulation materials/requirements between
replace surround and back wall
• size of oor plates in front of replace if required
• ue connection between rebox and chimney
• insulation requirements if ue passes through a
ammable wall
Chimney draught
Compared with older models, the clean burning inserts
of today put signicantly higher demands on the
chimney. Even the best insert 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 ue/chimney collar. At nominal heat
output there should be a negative pressure of 12 to 25
Pascal.
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 difcult to obtain the right draught conditions
in case the chimney is too large relative to the insert,
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 (FIG AIR_mm)
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. Insufcient
air supply can cause down-draught and thereby low
combustion efciency and the problems that this entails
soot stains on the glass, inefcient use of the wood and

10 GB
a soot deposits in the chimney.
For your own safety, comply with the assembly instructions.
All safety distances are minimum distances. Installation of the
insert must comply with the current rules and regulations of
the country where the product is installed. Nordpeis AS is not
responsible for wrongly assembled inserts.
Subject to errors and changes.

2. Technical information
The inserts from Nordpeis have secondary combustion
and are clean burning. The combustion takes place in
two phases rst the wood burns and then the gases
from the fumes are lit by the hot air. This ensures that
these new inserts have minimal emissions of soot parti-
cles and unburnt gases (such as CO) and are thus bet-
ter for the environment. Clean burning inserts require
a small amount of wood in order to obtain a good heat
output. Use exclusively clean and dry wood.

*Intermittent combustion refers to normal use of a replace,
i.e. new wood is inserted when the previous load has burned
down to ember
Warning If the requirements for ventilation are
NOT complied with, the heating circulation effect
will be considerably reduced and
overheating can occur.
This can in a worst case scenario cause a re.
3. Distance to combustible material
Ensure that the safety distances are respected
(FIG 2).
When connecting a steel chimney to the top outlet use
the security distances required from the manufacturer.
Floorplate
Please follow the rules and regulations regarding
oorplates in your country
Important! When placing the insert on a
combustible oor, a steel plate of at least 0.7mm
must cover the entire oor surface inside the
surround. Any ooring made of combustible
material, such as linoleum, carpets etc. must be
removed from underneath the steel plate.
The insert expands when in use, and for this
reason the insert must NEVER rest on the
surround, but have a gap of about 3 mm. The
insert must neither rest on the bench plate or
against the sides. It is recommended to dry
stack the surround in order to adjust the insert
prior to perforating the chimney for the ue
connection.
4. Assembly
Check the packing list to ensure that all loose parts
are included.
The door is opened by pulling the handle out FIG 4.
Assembly and adjusting the legs FIG 5
The insert is delivered with adjustable legs. These can
be mounted on the insert using the added washers and
bolts FIG 5.
Carefully lay the insert on its back. Ensure that the
transportation padding is put inside the insert before
turning it over, so that the insulating plates in the burn
chamber do not fall down and break.
Fasten the screws on to the insert with a 13 mm
spanner/wrench.
Adjust the legs (FIG 5) to the desired height before
returning the insert to an upright position (do not tilt
the insert). The height varies according to the
surround.

the air vent control.
FIG 7
The insert is delivered prepared for top connection. If
the insert is to be connected at the back, the ue outlet
collar must be placed according to FIG 8
FIG 8
Remove the cutout at the back of the radiation shield
(A). Remove the ue outlet cover and smoke outlet
collar (B). Mount the ue outlet collar on the back outlet
and t the ue outlet cover over the top outlet (C). The
insert can now be connected at the back.
Connection of the ue
Please be aware when connecting the 150 mm ue to
the smoke dome that the ue is placed outside the ue
outlet collar. *Alternative versions exsists due to
National requirements.
For the ue connection to the chimney, follow the
recommendations from the chimney manufacturer.
Operational control
When the insert is in an upright position, and prior to
mounting the surround, control that all functions are
easy to manoeuvre and appear satisfactory.
Air vent control
(Up in the centre FIG 6)
Left Completely open
Right Closed
Painting the Surround
It is recommended to use the insert a few times in
order to let the varnish harden before any masking and
painting. Only use water based breathing paint and a
designated masking tape. Carefully remove the tape in
order not to damage the varnish.
5. Lighting the re for the rst time
When the insert is assembled and all instructions have
been observed, a re can be lit. Be careful with
touching the insert the rst few times it is used as it may
damage the varnish. This is only true when the insert is
new and the varnish has not yet heat cured.
Avoid strong hits when inserting logs into the burn
chamber, in order not to damage the Thermotte plates.
Be aware that humidity in the insulation plates can
cause slow combustion at initial ring, which will be
resolved as the humidity evaporates. Possibly leave the
door slightly open the rst 2-3 times that the insert is
used.
It is advisable to air well when lighting a re for the
rst time as the varnish on the insert will release
some smoke or smell. This smoke and smell will
disappear and are not hazardous. When lighting the re
for the rst time we also recommend opening/shutting
the door regularly the rst two hours to aviod the door
gasket sticking to the varnish
Lighting a re
Open the vent control (FIG 6). Insert small dry pieces
of wood, ignite and ensure that the ames have a good
grip of the wood. Close the door when the ames are
stable and the chimney is warm. If it is not closed the
insert and chimney may overheat. The air supply is then
regulated with the vent control.
When there is a glowing layer of coal, new wood logs
can be inserted. Remember to pull the hot ember for-
ward in the insert when inserting new logs so that the
wood is ignited from the front. The vent control should
be opened each time new logs are inserted so that the
ames get a good grip. The re should burn with bright
and lively ames.
Using the insert with low combustion effect increases
the pollution as well as the risk of a re in the chimney.
Never allow the insert or ue to become glowing red.
Turn off the vent control should this happen. Regulation
of the vent control takes some experience, but after a
little while you will nd a natural rhythm for the re.
IMPORTANT! Always remember to open the air
vent control (preferably also the door) before
new wood logs are inserted into a hot burn
chamber. Let the ames get a good grip on the
wood before the air control setting is reduced.
When the draught in the chimney is low and
the vent is closed, the gas from the rewood
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 insert 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 insert must always be cold when
inspected.
Ashes
The ashes should be removed with regular intervals.
Be aware that the ashes can contain hot ember even
several days after the re is nished. 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

12 GB
with the Thermotte plates when the ashes are re-
moved, particularly when using an ash spade.
Thermotte™ plates
The thermotte plates (FIG 3) in the burn chamber
contribute to a high combustion temperature, which
leads to cleaner combustion of the wood and a higher
rate of efciency. Any ssures in the plates will not
reduce their insulation efciency.
If new plates are needed, contact your dealer. Please
note Wood logs that are too long can cause additional
strain and crack the plates, due to the tension created
between the side plates.
In case it is necessary to take out the Thermotte™
plates, this is done in following order.
A. Smoke bafe plate
B. Back plate
C. Front bottom plate
D. Bottom plate
E. Right side plate
F. Left side plate
Door and glass
Should there be any soot on the glass it may be
necessary to clean it. Use dedicated glass cleaner.
(Attention! Be careful, detergents can damage the
varnish and the gaskets). If different detergents are
used they may damage the glass. 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 soot on the glass and nish off with a piece
of clean and damp kitchen roll paper.
Attention! 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 including
ceramic glue.
Ceramic glass should
be disposed of as resid-
ual waste, together with
pottery and porcelain
CERAMIC GLASS
CANNOT BE
RECYCLED
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. If 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
For detailed description of the warranty conditions
see the enclosed warranty card or visit our website
www.nordpeis.com
The CE mark is placed on the side of the insert.
8. Advice on lighting a re
The best way to light a re 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 yers, magazines, milk cartons and similar
are not suitable for lighting a re. Good air supply is
important at ignition. When the ue is hot the draught
increases and door can be closed.
Warning: NEVER use a lighting fuel such as
petrol, karosine, alcohol or similar for lighting
a re. 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
re.
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.
Usage
Not enough air to the combustion may cause the glass
to soot. Hence, supply the re with air just after the
wood is added, so that the ames and gases in the

13
GB
combustion chamber are properly burnt. Open the air
vent and have the door slightly ajar in order for the
ames to establish properly on the wood.
Note that the air supply for the combustion also can
be too large and cause an uncontrollable re 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
ll the combustion chamber completely with wood.
It is recommended to keep an even re 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.
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.
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 ne wood, apart from when lighting
a re. This form of fuel can easily cause a
ashover that can lead to temperatures that are
too high.
Warning:
Make sure the insert is not overheated - it can
cause irreparable damage to the product. Such
damage is not covered by the warranty.

Some advice in case of combustion problems
Error Explanation Solution
No draught
The chimney is blocked. Contact a chimney sweeper / dealer for more information or clean
the ue, smoke bafe and burn chamber.
The ue is sooty or there is accumulated soot on the
smoke bafe.
The smoke bafe is wrongly positioned. Verify the assembly of the smoke bafe - see assembly instructions.
The insert
release smoke
when lighting
the re and dur-
ing combustion
Downdraught in the room caused by no draught, that the
house is too “air tight”.
Light the re 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 ues from two replaces/stoves are connected to the
same chimney at the same height.
One ue must be repositioned. The height difference of the two ue
pipes must be of at least 30 cm.
The ue is in a declining position from the smoke dome to
the chimney.
The ue 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 ue is too far into the chimney.
The ue must be reconnected so that it does not enter into the chim-
ney 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 replaces that are
not in use are open and create a false draught.
Close damper, doors and top draught vents on replaces that are
not in use.
An open hole in the chimney after that a replace 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 ue 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 retted, 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 replace 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 replace
releases smoke
inside when
it is windy
outside.
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
at.
Increase the height of the chimney and/or install a chimney cap/
smoke suction device*.
The replace
does not heat
sufciently.
The replace combustion receives too much oxygen due
to a leakage under the lower border of the insert or too
strong chimney draught. Difcult to regulate the combus-
tion and the wood burn up too quickly.
Any possible leakage must be sealed off. A draught regulator or pos-
sibly a damper can reduce the chimney draught. NB! A leakage of
only 5 cm2 is enough for 30% of the heated air to disappear.
Too much
draught
The smoke buffer is wrongly positioned. Verify the positioning of the smoke buffer – see assembly instruc-
tions.
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 at. Replace the gaskets, contact your dealer.
The chimney is too large. Contact chimneysweeper or other professional for more details.
The glass is
sooty
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 ames have a good
take on the wood.
White glass
Bad combustion (the temperature is too low). Follow the guidelines in this user guide for correct combustion.
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
released when
the door is
opened
A levelling out of pressure occurs in the burn chamber. Open the air vent control for about 1 min before opening the door –
avoid opening the door too quickly.
The door is opened when there is a re in the burn
chamber. Open the door carefully and/or only when there is hot ember.
White smoke The combustion temperature is too low. Increase the air supply.
The wood is humid and contains water damp. Ensure to use only dry and clean wood.
Black or grey/
black smoke Insufcient combustion. Increase the air supply.
