an inammable container to remove the ashes. It is
recommended to leave a layer of ashes in the bottom
as this further insulates the burn chamber.
Thermotte® Plates (insulation plates)
These heat-insulating plates in the burn chamber
contribute to a high combustion temperature, a
better gas exhaustion of the wood and a higher rate
of efciency. The plates are not harmful and are
exchanged when worn (less than half of their original
thickness). Any ssures in the Thermotte® plates will
not reduce their insulation efciency. If you need new
plates, contact your dealer. Their original thickness is
28 mm. Please note: Too long wood logs can cause
additional strain and crack the plates, due to the
tension created between the side plates.
Cleaning and Inspection
The insert should be inspected thoroughly and
cleaned at least once per season (possibly in
combination with the chimney and chimney pipes
being swept). Ensure that all joints are tight and that
the gaskets are rightly positioned. Exchange any
gaskets that are worn or deformed.
7. Warranty
The steel inserts from Nordpeis AS benet of a 5-year
warranty. Any claim during this period should primarily
be made to the dealer who sold the insert. The
warranty does not include normal wear and tear on
items such as: Thermotte® plates, smoke bafe, glass
and gaskets. New parts can be ordered at your dealer.
The warranty does not include damages that are
caused by wrong handling or misuse of the insert
(see section Advice on lighting a re). The warranty
only entails the product. There is no compensation for
third party damage or damage to other items caused
by use of the insert. Demounting, remounting, delays
and transport are not covered for any fault that can be
noticed before assembly. A dated invoice is required
for any repair covered by the warranty.
The inserts have a plaque with the SINTEF number
on the inside of one of the legs. N-23G Sintef nr:
110-0264. Complete product documentation can be
downloaded at www.nbl.sintef.no.
The CE mark is situated on one of the sides of the
insert.
8. Advice on making up a re
The best way to make up a re is with the use of re
briquettes. Newspapers cause a lot of ashes and
the ink is damaging for the environment. Advertising
yers, magazines and milk cartons etc are not suitable
for making up a re. It is extremely important that
clean and dry wood is used at all times.
Humid wood requires a lot of air for the combustion,
as extra energy/heat is required for drying the humid
wood. The heat effect is therefore minimal. In addition
this causes soot creation in the chimney with the risk
of creosote and chimney re.
Combustion complications
Too much air supply to the combustion creates an
uncontrollable ame that very quickly will heat up the
entire insert to extremely high temperatures (valid
when heating with closed or almost closed door).
Never completely ll up the burn chamber with wood,
as this can reduce the lifetime of the Thermotte®
plates signicantly as it can cause ssures in the
plates.
Some technical information on combustion
In order to obtain an optimal combustion, the
temperature needs to reach 600-800ºC. It is
recommended to keep an even re with a small
amount of wood. If too many logs are put on the hot
ember, the air supply will not be sufcient for reaching
the require temperature, and the gases will go out
un-burnt. For this reason it is important to increase the
air supply just after adding the logs in order to have
proper ames in the burn chamber so that the gases
are burnt.
Use split wood logs rather than whole round pieces of
wood. This will give a better heat effect and cleaner
combustion. The inserts from Nordpeis are intended
for, and only approved for, wood combustion.
NB! Handle the Thermotte® plates with care
when emptying the ashes, especially when
using an ash spade.
Warning: NEVER use a lighting fuel such as
petrol, parafn, methylated spirits or similar for
lighting a re. This could cause you injury as
well as damaging the product.
Warning: NEVER use impregnated wood,
painted wood, plywood, chipboard, rubbish,
milk cartons, and printed material or similar. If
any of these items are used as fuel the warranty
is invalid, as they can contain hazardous,
etching and dangerous fumes when burnt.
In addition the poisonous gas dioxin can
develop, that can damage the insert and be
harmful to the environment.
Warning: Be careful that the product is not
overheated, as this can cause irreparable
damage, which is not covered by the warranty.
