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 re.
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 ue. Consider possible inclination of the ue
prior to perforating the chimney. Distortions in oors and walls
may also inuence the height. Place the stove for accurate
height and positioning of the ue/chimney connection.

2. Technical information
The stoves from Nordpeis all 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 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%.

1. Before installing a new stove
All our products are tested according to the latest
European requirements. 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:
• 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 stoves
of today put signicantly 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. Recommended eective chimney height is
minimum 4 meters. 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 dicult 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 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 aected 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. Insucient
air supply can cause down-draught and thereby low
combustion eciency and the problems that this entails:
soot stains on the glass, inecient use of the wood and
a soot deposits in the chimney.
