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.
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
cases you should 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
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 draft
enough. In such
recommended.
Insufficient
Warning! Keep the air intakes, supplying
combustion air, free from blockage.
If the requirements for ventilation are
NOT complied with, the product can overheat.
This can cause a fire.
Warrning! Extractor fans when operating
in the same room or space as the appliance
may cause problem.
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.

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%.
