1. Prior to assembling the insert
All our products are tested according to the latest
9
European requirements and also to the Norwegian
9
standard NS 3058 and NS 3059, which include
9
particle tests. However, several European countries
10
have local regulations for installation of fireplaces,
which change regularly. It is the responsibility
10
of the client that these regulations are complied
10
with in the country/region where the fireplace is
11
installed. Nordpeis AS is not responsible for incorrect
11
installation.

Important to check
11
(please note that this list is not exhaustive):
•
distance from firebox to combustible/flammable
11
materials
12
•
insulation materials/requirements between
12
fireplace surround and back wall
12
•
size of floor plates in front of fireplace if required
12
•
flue connection between firebox and chimney

•
insulation requirements if flue passes through a
flammable wall

Chimney Draught
Compared with older models, the clean burning
inserts of today put significantly higher demands
14
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. At nominal effect there should be a
negative pressure of 12 to 25 Pascal.
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.
Air Supply (FIG N-20F AIR)
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
