Shared Flue Gas System; Air Supply; Technical Information - Nordpeis Q-24UL Manuel D'installation

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 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.
Shared flue gas sytem
Appliance can be connected to shared flue gas pipe
system.
Warning! In case of the appliance connected to
shared flue gas pipe system - the Self Closing
Door system must be operational. See Paragraph
4. Assembly - Self Closing Door.
Air supply (=mm AIR)
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 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
inserts.

2. Technical information

Inserts 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 heated air. This
ensures that new inserts have minimal emissions of
soot particles and un-burnt gases (such as CO) and
are thus better for the environment. Clean burning
inserts require a small amount of wood to obtain good
heat output. Use exclusively clean and dry wood. We
recommend seasoned hardwood with a maximum
moisture content of 20%.

Operation
* Intermittent combustion refers to normal use of a fireplace, 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 cooling airflow around the
product will be considerably reduced and
the product can overheat.
This can cause a fire.
