1. Prior to assembling the insert
All our products are tested according to the latest
European requirements and also
to the Norwegian
standard NS 3058 and NS 3059,
which include particle
tests. However, several European countries have local
regulations for installation of fireplaces, which change
regularly. It is the responsibility of the client that these
regulations are complied with in the country/region
where the fireplace is installed. Nordpeis AS is not
responsible for incorrect installation.
Important to check
(please note that this list is not exhaustive) :
• distance from firebox to combustible/flammable
materials
• insulation materials/requirements between
fireplace surround and back wall
• size of floor plates in front of fireplace if required
• flue connection between firebox and chimney
• insulation requirements if flue passes through a
flammable wall
• an access for cleaning the appliance, the flue gas
connector, the chimney flue must be provided
Chimney draft
Compared with older models, the clean burning inserts
of today put significantly higher demands 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. 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.
