Congratulations on purchasing a new replace insert from Nordpeis.
Your replace insert has been tested and documented by the National Fire Laboratory of Norway,
SINTEF, to assure it’s safety and environmental compliance. SINTEF test requirements are amongst

The purpose of this manual is to provide guidance on how to operate your new appliance safely and
efciently – we can not stress the importance of reading this manual before using your appliance
enough.
It is your responsibility to ensure that the wood you intend to burn on this appliance is well seasoned
(a minimum of 2 years old with a moisture content of no more than 20%) – this will enable your re-
place insert to operate efciently.
Nordpeis have over 30 years of experience in developing and manufacturing stoves and replace
inserts. We only introduce our products to the marketplace after several years of research and testing
on our combustion techniques have taken place.
We thank you for chosing a Nordpeis product and hope it will give you many years of warmth and
comfort in the future.

IMPORTANT INFORMATION
This appliance must be installed in line with current building regulations either by a registered
installer or in conjunction with your local Building Inspector. If in doubt, please consult your
stockist or local planning ofce.
If installed incorrectly, this appliance could contribute towards serious accidents and / or
damage to your property and could invalidate your warranty.
The manufacturer’s responsibility is limited to the supply of this appliance.
We recommend that a reguard is used in the presence of children and old / inrm people for
safety.
The installer should comply with Health & Safety regulations.
Adequate facilities should be provided for handling the appliance.
Extra care should be taken to avoid accidents and breakage of the glass panels.
Care should be taken to avoid re cement contacting the skin. The material is caustic and in
the event of skin coming into contact with the re cement, wash off immediately with clean
water.

1. Before installation
Make sure the chimney is in good working order and that the required chimney draft of between 14
– 25 Pascal negative is obtained. A minimum chimney height of 4meters is required. The chimney
must be Class I – suitable for use with wood. Please ensure the chimney is swept prior to installing
the appliance. The chimney is the key to successful installation and operation of the appliance. If the
chimney is in poor condition or of the wrong design or construction the performance will be adversely
effected and problems will be experienced with combustion and possible smoke emission into the
room. The chimney should be one of the following types:-
• Brick built with suitable liner for use with wood / solid fuel appliances
• Twin wall stainless steel approved for use with both wood / solid fuel appliances
• Prefabricated “concrete” type systems approved for use with wood / sold fuel
appliances
DO NOT USE FLEXIBLE LINERS DESIGNED FOR USE ONLY WITH GAS APPLIANCES
NEVER ALLOW THE APPLIANCE TO CARRY THE WEIGHT OF THE CHIMNEY
You must ensure that there is sufcient fresh air supply within the room as per Building Regulations. If
insufcient fresh air is provided this will lower the atmospheric pressure within the room and may lead
to poor combustion and smoke leakage from the appliance. We recommend that a minimum airbrick
of 33cm² is installed (54cm² for installations with ue draft stabilisers).
The replace should stand on a reproof hearth suitably constructed from materials which are able to
support the weight of the appliance and the ue system. The hearth needs to be 300mm to the front
of the appliance and 150mm to each side of the replace and must conform to current Building Regu-
lations. You must ensure that the hearth can not be inadvertently be covered by carpet, rugs etc – this
can be done by adding a kerb etc.
The following clearances around the replace must be observed to allow the correct operating proce-
dure:-
75mm either side of the replace
200mm above the replace to non-combustible material
380mm above the replace to combustible material
We have on page 19 placed a check form you can use to prove correct installation of your new re-
place.

4. Installation site
Make sure not to under exceed any safety distances. The replace should be sited with the appliance
door no less than 1 meter away from combustial materials. When mounting steel chimney on top of
the replace we refer to the assembly manual from the respective chimney manufacturer. Comply with
the safety distances that are required when mounting a steel chimney.
The replace insert model and the concrete surrounding determines height on rewall. The distance
between smoke pipe and ammable wall & construction must be at least 300 mm. The shortest dis-
tance between upper air outlets or top of concrete surrounding must be at least 380 mm.
All measures are approximately as misalignment in wall and oor, and distance
to centre of smoke inlet into chimney can vary.

5. Assembling N-21/N-24
The following tools are necessary:
13-mm. spanner
Drill / screwdriver for crosshead screws
Caulking gun
Possibly a hammer
First you should run an inventory on all loose parts, and it should contain the following parts (look
at gure 1 (N-21) and gure 2 (N-24):

IMPORTANT! Be careful when touching the re insert during it’s rst rings as the paint will
be very soft until it has cured. It can take several rings to cure the paint.

Adjust the length of the legs to t the concrete frame.
Working range of legs:
From: To:
For N-21: 224 mm 330 mm
For N-24: 240 mm 330 mm
Now raise the inset back into upright position (do not tilt, but lift
the insert back into upright position)
•

Carefully place the inset on it’s back and start assembling the legs this way:
Fasten adjustment screws to the legs (you might want to give the screw a stroke with the hammer
to get in place as shown in gure 3a). The nut should be xed into the hexagonal hole.
Fasten the legs to the body by using the accompanying screws (gure 3b). The leg must surround
the supporting bracket under the inset, as shown in gure 3c. The vertical opening in the legs
should point towards the centre.
