Shared Flue Gas System; Technical Information - Nordpeis N-20 U Manuel D'installation

Shared flue gas system

Appliance can be connected to shared flue gas pipe
sytem. In case of simultaneous operation with other
heating appliances, there must be sufficient combustion
air provided.
Warning! In case of the appliance connected to
shared flue gas pipe system - the Self Closing
Door system must be operational. See FIG 9
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.
Warrning! Extractor fans when operating
in the same room or space as the appliance
may cause problem.
Warning: Keep the air intakes, supplying
combustion and convection air free from blocka-
ge. If the requirements for ventilation are
NOT complied with, the product can overheat.
This can cause a fire.
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.
Subject to errors and changes.

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%.
