Chimney draught

Compared with older models, the clean burning inserts
of today put significantly 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 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
• 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 insert,
as the chimney does not heat up well enough. In such
cases you sould 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 an 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 constructions, we strongly
recommend the product is designed and prepared
for direct supply of outside air. In older houses also,
the use of fresh air supply set is also recommended.
Insufficient air supply can cause poor draught and
thereby low combustion efficiency and the problems this
entails: soot stains on the glass, inefficient utilisation of
the wood and a soot deposits in the chimney.
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, fully 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 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%.
