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 particle
9
tests. However, several European countries have local
regulations for installation of fireplaces, which change
10
regularly. It is the responsibility of the client that these
regulations are complied with in the country/region
10
where the fireplace is installed. Nordpeis AS is not
responsible for incorrect installation.

Important to check
10
(please note that this list is not exhaustive):
11
• distance from firebox to combustible/flammable
11
materials
11
• insulation materials/requirements between
11
fireplace surround and back wall
11
• size of floor plates in front of fireplace if required
11
• flue connection between firebox and chimney
• insulation requirements if flue passes through a
11
flammable wall
• an access for cleaning the appliance, the flue gas
12
connector, the chimney flue must be provided

Chimney draft
12
Compared with older models, the clean burning inserts
12
of today put significantly higher demands on the
chimney. Even the best insert will not work properly
13
if the chimney does not have the right dimensions or
13
is not in good working order. The draught is mainly
controlled by gas temperature, outside temperature, air
14
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.
Attention! Adverse flue draught or adverse weather
conditions, e. g. mist, wind etc., may interfere the
necessary flue draught. This should be checked be-
fore lightening the fireplace. If there is no necessary
flue draught in the chimney, the use of the fireplace
should be avoided.
