8. Warranty

The cast iron parts of Trio from Nordpeis AS have a
5-year warranty. Any claim during this period should
primarily be made to the dealer who sold the stove.
The warranty does not include: Thermotte® plates,
smoke baffle, glass and gaskets. By normal wear and
tear on above mentioned parts, new parts can be
ordered at your dealer.
The warranty does not include damages that are
caused by wrong handling or misuse of the stove;
e,g, overheating due to incorrect regulation of the air
supply or the use of incorrect fuel.
The warranty only entails the product. There is no
compensation for third party damage or damage to
other items caused by use of the stove. 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 stoves has Sintef number: 110-0301.
Complete product documentation can be downloaded
at www.nbl.sintef.no.
The CE mark is situated under the top lid.

9. Advice on making up a fire

The best way to make up a fire is with the use of fire
briquettes. Newspapers cause a lot of ashes and
the ink is damaging for the environment. Advertising
flyers, magazines and milk cartons etc are not suitable
for making up a fire.
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 fire.
Warning: NEVER use a lighting fuel such as
petrol, paraffin, methylated spirits or similar for
lighting a fire. 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 release dioxin
gas that can harm the stove when burnt. These
gasses are also very hazardous for you and the
environment

Combustion complications

Too much air supply to the combustion creates an
uncontrollable flame that very quickly will heat up the
entire stove to extremely high temperatures (valid
when heating with closed or almost closed door).
Never completely fill up the burn chamber with wood,
as this can reduce the lifespan of the Thermotte®
plates significantly ands it can cause fissures 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 fire with a small
amount of wood. If too many logs are put on the hot
ember, the air supply will not be sufficient 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 flames 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 stoves from Nordpeis are intended
for, and only approved for, wood combustion.

Chimney Draught

The chimney is an important factor for getting the
most out of the hearth. Even the best stove will
not work properly if the chimney does not have the
right dimensions or is not in good working order.
Recommended draught is 14-25 Pascal.
Warning: Be careful that the product is not
overheated, as this can cause irreparable
damage, which is not covered by the warranty.
Draught Conditions
The draught is mainly controlled by: gas temperature,
outside temperature, air supply and the height of the
chimney.
The draught increases when:
•
The chimney becomes warmer than the outside air
•
The active length of the chimney increases (over
the hearth)
•
Good air supply to the combustion
It can be difficult to obtain the right draught conditions
in case the chimney is too large in relationship to the
stove, as the chimney does not heat up well enough. If
possible, insert a smaller chimney pipe. Draught that
is too strong can also be controlled with a damper.

Heat Creation and Distribution

There are two different types of heat: radiation and
convection heat. The heat created in the space
between the stove and surround is what is called
convection heat. Cold air is sucked in at floor level
