Shared Flue Gas System; Air Supply; Technical Information - Nordpeis S-31A Manuel D'installation

Shared flue gas sytem
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 (FIG AIR_mm)
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 recommended. Insufficient
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.
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 blockage.
If the requirements for ventilation are
NOT complied with, the product can overheat.
This can cause a fire.
For your own safety, 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

The inserts from Nordpeis 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 inserts have minimal emissions of soot parti-
cles and unburnt gases (such as CO) and are thus bet-
ter for the environment. Clean burning inserts require
a small amount of wood in order to obtain a good heat
output. Use exclusively clean and dry wood.
